Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a portable telephone terminal.

[0002]

2. Description of the Related Art Portable telephone terminals have been widely used. 2. Description of the Related Art A mobile phone terminal can be carried around in a user's jacket pocket or bag, and can easily receive and make a call by wireless communication when going out. Therefore, excellent portability and operability are required.

In many mobile phone terminals, the functions of the telephone are mounted on one housing, and operation keys such as a speaker (receiver), a display, and a dial key are mounted on the same surface (front surface) of the same housing. , A microphone (transmitter) and the like are arranged, so that they can be easily carried and operated.

[0004] Among mobile telephone terminals, a so-called flap type foldable mobile telephone terminal is also provided. This flap type mobile phone terminal is composed of, for example, a first portion having a speaker and a display, and a second portion having an operation key portion and a microphone, and does not make a call. Sometimes
The first portion can be folded so that the surface on which the speaker or display is provided and the second portion on which the operation keys or microphones are provided face each other.

[0005] In the case of such a flap type mobile phone terminal, it can be folded, so that the portability is good. Further, when the mobile phone terminal is folded, the operation key portion is located inside, so that the foreign matter is removed. For example, the operation key is not accidentally pressed by the user.

[0006] In the case of a portable telephone terminal, a whip antenna that can be pulled out is built in to enable good telephone calls indoors and outdoors. When a call is made, the built-in whip antenna is pulled out from the mobile phone terminal so that signals can be transmitted and received between the base station and the base station, so that a good call can be made.

[0007] In addition, the display of the portable telephone terminal includes:
Information such as a display indicating a communication state between the base station and the terminal, a remaining battery level display, a date, a current time, and an input telephone number at the time of calling is displayed. By the display of this display,
The user can check the status of his or her own device, the date, the date and time, and the telephone number of the other party to call.

[0008]

By the way, as described above, in the case of a portable telephone terminal, it is necessary to pull out an antenna when receiving a telephone call and when making a telephone call in order to make a good call. However, when using the mobile phone terminal, the antenna must be pulled out one by one, and the antenna must be turned off when the call is completed, which is troublesome.

Further, when the antenna is pulled out, the antenna may hit the hair or the hat and may be in the way. Also,
The antenna of the mobile phone terminal is a relatively thin rod-shaped antenna, and is highly likely to bend or break when being taken in and out.

In addition, the same surface (front surface) of the same housing described above.
In the case of a mobile phone terminal in which a speaker (receiver), a display, operation keys such as dial keys, a microphone (transmitter) and the like are arranged, the operation keys are always exposed. For this reason, for example, when the mobile phone terminal is carried around in a bag, a foreign object or the like may touch the operation key and cause the mobile phone terminal to malfunction.

For this reason, a cover is provided at a portion where the operation keys are arranged, or a so-called key lock function is provided so that when the key lock switch is turned on, even if the operation keys are pressed, the operation keys are not accepted. It is also possible.

However, when the user forgets to close the cover or does not turn on the key lock switch, the user can press the operation key to operate the mobile phone terminal.
It is not possible to reliably prevent a malfunction due to an unintended pressing of an operation key by a user.

In consideration of this point, the above-mentioned so-called flap-type mobile phone, when folded,
Since the operation key cannot be pressed, erroneous operation due to the user's unintended pressing of the operation key can be prevented.

However, there are cases where conventional mobile phone terminals, including flap-type mobile phone terminals, cannot sufficiently cope with new demands as described below.

For example, recently, a telephone number of a calling party is provided to a called telephone terminal, and this is displayed on a display of the called telephone terminal before the called user goes off-hook. Providing a so-called call ID service that can perform such services is becoming a reality.

[0016] A service is also considered in which a relatively long message data or graphics data of about 160 characters is transmitted from a caller and displayed on a display of a mobile telephone terminal of a called party. In this case,
As in the case of the above-described call ID service, it is desirable that the called mobile phone terminal can display as much of the transmitted message data on the display as possible, regardless of whether or not the off-hook operation has been performed.

As described above, the type and amount of information to be displayed on the display of the portable telephone terminal before going off-hook is increasing. For this reason, there is an increasing demand for making the display of the mobile phone terminal as large as possible.

However, in the case of the above-mentioned flap type portable telephone terminal, when the telephone number of the caller is notified by the call ID service or when message data is received, the portable telephone terminal is opened from the folded state. You can't see what you see on the display unless you put it in the upright position. Therefore, it may not be possible to immediately see the telephone number of the caller by the call ID service or the transmitted message data.

Further, since a portable telephone terminal is required to be excellent in portability and operability, the display cannot be easily enlarged. That is, in the case of the above-described mobile phone terminal in which the speaker, the display, the operation keys, and the microphone are located on the same surface of the same housing,
In order to increase the size of the display, it is necessary to increase the size of the entire mobile phone terminal or to reduce the size of a portion other than the display, such as a speaker, an operation key unit, and a microphone.

However, when the whole is enlarged, a problem arises in terms of portability, such as difficulty in entering a jacket pocket or a bag. In addition, when a portion other than the display, such as a speaker, an operation key unit, and a microphone, is reduced, problems arise in terms of operability and functionality, such as difficulty in pressing operation keys and difficulty in hearing the voice of the other party.

In view of the above, it is an object of the present invention to eliminate the above problems and to provide a more convenient mobile phone terminal.

[0022]

In order to solve the above-mentioned problems, according to the present invention, there is provided a portable telephone terminal comprising:
A display unit, a main unit including a speaker, and at least a dial operation key, and an operation panel unit provided with a microphone, wherein the operation panel unit includes:
By sliding with respect to the main body, storage in the main body and withdrawal from the main body can be performed.When the operation panel is housed in the main body, the operation panel is A mobile phone terminal which is inoperable by being concealed by a housing of the main body.

A portable telephone terminal according to a second aspect of the present invention is the portable telephone terminal according to the first aspect, wherein the display means of the main body section is such that the operation panel section slides. Thus, it is provided on the surface of the main body that is not concealed.

According to a third aspect of the present invention, there is provided a mobile phone terminal according to the first aspect, wherein the operation panel section includes a first antenna. And

According to the portable telephone terminal according to the first aspect of the present invention, the operation panel section having the microphone and the dial operation keys slides with respect to the main body section having the speaker and the display means, thereby performing this operation. The panel unit can be stored in the main unit and pulled out from the main unit. Then, when the operation panel section is stored in the main body section, the operation panel section is concealed by the housing of the main body section so that it cannot be operated.

Thus, when the operation panel portion is housed in the main body portion, it is possible to prevent a malfunction due to an unintended pressing of the operation key by the user, such as a foreign object touching the operation panel portion.

Further, since the microphone and the dial operation keys are provided on an operation panel different from the main body having the speaker and the display means, they are displayed on the main body without being affected by the arrangement space of the microphones and the dial operation keys. Display means having a large area can be provided.

According to the portable telephone terminal according to the second aspect of the present invention, the display means provided on the main body includes:
The operation panel unit is provided on a surface of the main body unit which does not become obstructed by being slid by the operation panel unit.

Thus, the display means of the main body can be instantaneously viewed at any time, regardless of whether or not the operation panel is housed in the main body.

According to the third aspect of the present invention, the antenna is built in the operation panel unit. When the operation panel unit is housed in the main unit, the antenna is located in the main unit as in the case of the conventional mobile phone terminal, and transmits and receives signals to and from the base station such as standby reception. Will be able to.

When receiving an incoming call or making a call from the user, the operation panel is pulled out of the main body, so that the antenna built in the operation panel is also pulled out of the main body at the same time. It is.

Thus, when the operation panel section is pulled out of the main body, signals can be transmitted and received more favorably than when the antenna is inside the main body. Also,
Since the antenna is built in the operation panel unit, the antenna is not damaged.

Next, the operation of the portable telephone terminal according to the first embodiment will be described. As described above, this mobile phone terminal is capable of transmitting and receiving voice signals and transmitting and receiving character data and graphic data.

[Transmission and Reception of Voice Signal] First, the operation of transmitting and receiving a voice signal using the function of the portable telephone terminal as a telephone will be described.

The antenna 1 receives a signal from the base station on the telephone station side and transmits a signal from the portable telephone terminal. As described above, the mobile phone terminal according to the present embodiment is configured such that the operation panel unit 30 can be stored in the main body unit 10 during standby reception. Therefore, at the time of standby reception, FIG.
As shown in B, the antenna 1 is located in the main body 10.

The signal from the base station received by the antenna 1 is supplied to the receiving circuit 22 through the antenna duplexer 21. Here, the antenna duplexer 21 prevents the signal transmitted from the mobile phone terminal from interfering with the received signal.

The receiving circuit 22 includes a frequency synthesizer 24
, And performs standby reception for detecting whether or not the selected signal includes a signal for notifying an incoming call to the terminal itself.

According to the control of the control circuit 6, the frequency synthesizer 24 instructs the receiving circuit 22 on the frequency of the signal to be received, as described above, and sends the transmitted signal to the transmitting circuit 23 to be described later. It indicates the frequency of the signal transmitted from the terminal.

When the receiving circuit 22 detects a signal for notifying its own device of an incoming call, it notifies the control circuit 6 that there is an incoming call. The control circuit 6 receives a notification from the receiving circuit 22 that there is an incoming call to the mobile phone terminal, and drives a calling bell or a vibrator provided in the mobile phone terminal to emit a ringing sound (not shown), The user is informed that there is an incoming call by vibrating the own device.

When the user performs an off-hook operation, the telephone line is connected, and the voice signal transmitted from the call destination is supplied to the modem circuit 3 via the receiving circuit 22.

In the portable telephone terminal of this embodiment, the operation panel unit 30 housed in the main body 10 can be pulled off from the main body 10 so as to be able to go off-hook. When the call is finished, the operation panel unit 30 can be put on-hook by being stored in the main body unit 10.

Further, as described above, the operation panel section 30 is pulled out of the main body section 10 to make a call, and when the call is completed, the operation panel section 30 is provided in the main body section 10 without being housed in the main body section 10. The on-hook can also be performed by pressing the end key 15 provided.

When the operation panel section 30 is pulled out of the main body 10 and the operation panel section 30 is pulled out of the main body section 10, the end key 15 is pressed to go on-hook. By pressing the transmission key 11, the mobile phone terminal of this embodiment can be off-hook.

A magnetic sensor 40 provided on the main body 10 and a magnet 33 provided on the operation panel 30 are provided.
Whether the operation panel unit 30 is housed in the main body 10 or the main body 10
It is detected whether it has been pulled out of the device.

Therefore, there is an incoming call to the portable telephone terminal, and the operation panel unit 3 stored in the main unit 10
0 has been pulled out of the main body 10 by the magnetic sensor 4.
When 0 is detected, the control circuit 6 determines that the operation is an off-hook operation.

Further, when there is an incoming call to the portable telephone terminal, and the operation panel unit 30 is pulled out from the main unit 10 and is on-hook, the main unit 10
When the control circuit 6 detects that the transmission key 11 provided on the control unit 11 is pressed, the control circuit 6 determines that the operation is an operation of off-hook.

The modulation / demodulation circuit 3 demodulates the voice signal transmitted from the call destination,
To supply. The baseband processing circuit 4 is a modulation / demodulation circuit 3
The original baseband signal is extracted from the audio signal supplied from, and supplied to the codec circuit 5.

The codec circuit 5 performs D / A conversion on the supplied baseband signal, and then supplies it to a speaker (receiver) 7. As a result, the sound transmitted from the call destination is emitted from the speaker 7.

Further, codec circuit 5 also performs A / D conversion processing of an audio signal transmitted from the portable telephone terminal of this embodiment. That is, the sound picked up by the microphone (transmitter) 31 provided on the operation panel unit 30 drawn out of the main body unit 10 is supplied to the codec circuit 5, where it is A / D converted and converted to baseband. A signal is formed. This baseband signal is supplied to the baseband processing circuit 4.

The baseband processing circuit 4 performs processing such as error correction and channel coding on the baseband signal from the codec circuit 5 and supplies the processed signal to the modulation / demodulation circuit 3.

The modulation / demodulation circuit 3 includes a baseband processing circuit 4
Modulates the signal supplied from to form a signal for transmission,
This is supplied to the transmission circuit 23.

The transmission circuit 23 performs processing such as amplifying the signal for transmission to a predetermined level, and performs processing such as adjusting the frequency of the signal for transmission in accordance with an instruction from the frequency synthesizer 24. . Then, the transmission circuit 23
The transmission signal adjusted in is supplied to the antenna 1 via the antenna sharing device 21 and transmitted from the mobile phone terminal.

The control circuit 6 of the portable telephone terminal according to the present embodiment is composed of a microcomputer having a CPU, a ROM, a RAM, and the like, and controls each part of the portable telephone terminal.

As described above, the mobile phone terminal of this embodiment slides the operation panel section 30 with respect to the main body section 10 so that the operation panel section 30 is moved to the main body section 10 as shown in FIG. 1B. The operation panel section 30 can be pulled out of the main body section 10 as shown in FIG. 1A.

When the operation panel section 30 is housed in the main body section 10, the operation panel section 30 is covered by the main body section 10 so that the operation keys such as the dial operation keys cannot be touched. Is done. As a result, a foreign object does not press the operation key,
Malfunction can be prevented.

Further, a so-called key lock button switch or the like is provided to prevent the operation key from being accepted even when the operation key is depressed, so that erroneous operation of the operation key at the time of standby reception or the like is prevented. Without pressing the key lock button switch, the operation panel 3
When the “0” is stored in the main body unit 10, the operation on the operation panel unit 30 cannot be reliably performed.

Further, since the antenna 1 is built in the operation panel section 30, it is not necessary to pull out the antenna 1 from the main body section 10 alone. The antenna 1 is also pulled out of the main body 10 by being pulled out from the main body 10.

Therefore, the antenna 1 can be safely and quickly pulled out of the main body 10 without bending or breaking the antenna 1. When the operation panel section 30 is pulled out of the main body section 10, the antenna 1 can transmit and receive signals better than when the antenna 1 is located in the main body section 10.

Further, in the portable telephone terminal of this embodiment, the microphone 31 and the dial operation key group 32 are provided not on the main body 10 but on the operation panel portion which can be stored in the main body 10. For this reason, the display 8 provided in the main body 10 is not affected by the arrangement space of the microphone 31 and the dial operation key group 32 and the like,
A relatively large display area can be obtained.

As a result, more information can be displayed on the display 8 than before. The display 8 is connected to the operation panel section 30 regardless of whether the operation panel section 30 is slid and stored in the main body section 10 or pulled out of the main body section 10.
It does not disappear because it is covered with. That is, since the display 8 is always exposed, the information displayed on the display 8 can be immediately viewed.

As described above, the portable telephone terminal according to this embodiment has a large display area of the display 8 and can display a large amount of information, and can immediately view the information displayed on the display 8 at any time. So you can
This is very effective when character data described below is received and displayed.

[Transmission / Reception of Character Data, etc.]
An operation of transmitting and receiving character data and the like in the mobile phone terminal of this embodiment will be described.

As in the case of the above-described audio signal receiving process, the receiving circuit 22 selects a signal of the frequency designated by the frequency synthesizer 24 and adds character data or graphic data to its own device. Standby reception is performed to detect whether or not a signal indicating that data is transmitted is included.

When the receiving circuit 22 detects a signal indicating that character data or graphics data is transmitted to its own device, it notifies the control circuit 6 of the signal. The control circuit 6 drives the calling bell or vibrator included in the mobile phone terminal, emits a ringing tone, vibrates the own device, and transmits character data and graphics data to the own device. To the user.

In this case, the ring tone and vibration of the portable telephone terminal are different between the case where character data and the like are transmitted and the case where a call is received as described above.

When the character data and the graphics data are transmitted to the own device in this manner, there is no need to perform a two-way communication as in the case of the transmission and reception of the voice signal described above. Without waiting for an off-hook operation, character data automatically transmitted is received, and information based on the received data is displayed on the display 8.

Therefore, a signal such as character data transmitted from the calling party is transmitted via the receiving circuit 22 to
The signal is supplied to the modulation / demodulation circuit 3, where it is demodulated and supplied to the baseband processing circuit 4. Baseband processing circuit 4
Extracts the transmitted data such as character data from the signal supplied from the modulation / demodulation circuit 3 and supplies it to the control circuit 6.

The control circuit 6 is a microcomputer as described above. And, in the ROM of the control circuit 6,
A program executed by the CPU of the control circuit 6 of the mobile phone terminal, data necessary for various processes, or
Character font data and the like are recorded. The control circuit 6 includes, in addition to the ROM and the RAM used as a work area, a VRAM (video RAM) in which information to be displayed on the display 8 is formed, a display controller for controlling the display 8, and the like. Things.

The control circuit 6 forms character information and graphics information to be displayed on the display 8 based on the data supplied from the baseband processing circuit 4, and displays them on the display 8.

The display 8 of the portable telephone terminal of this embodiment has a large display area and can display a lot of information, as shown in FIG.
Further, the display 8 has an operation panel section 30 that is the main body section 1.
In both the state where the mobile phone is stored in the main unit 10 and the state where the mobile phone is pulled out from the main body 10, the mobile phone is located at the outermost side.

Therefore, the user can immediately see a lot of information displayed on the display 8 simply by taking out the mobile phone terminal of this embodiment from, for example, a jacket pocket or a bag.

Further, since the display 8 is larger than the conventional one and more information is displayed, for example, it is less likely that one sentence cannot be displayed at a time, so that the contents of the displayed information can be quickly recognized. Can be.

Of course, when a large amount of transmitted character data or the like cannot be displayed on the display 8 at one time, the whole screen can be viewed by displaying the next screen and the previous screen. .

Also, the mobile phone terminal of this embodiment
As will be described later, information received and displayed on the display 8 can be stored in the memory 61 of the control circuit 6. Then, for example, by operating the jog dial 14, the information stored in the memory 61 can be read out when necessary and viewed any number of times.

Further, the portable telephone terminal can create and transmit message data in its own device. That is, in the case of the mobile phone terminal of this embodiment, alphabetic characters (alphabet characters) and katakana characters are assigned to the dial operation keys such as 0 to 9, *, and #. The conversion key 12 provided on the main body 10 is a conversion key for English / Kana / Kanji / numeric characters. By operating the dial operation key group 32 and the conversion key 12, message data can be input to the mobile phone terminal.

The input message data is supplied to the control circuit 6. The control circuit 6 displays the input message data on the display 8 to receive a fixed input indicating that the modification input and the input of the message data have been completed. This is stored in, for example, the memory 61 and transmitted to the destination according to the instruction from the user.

In this case, the message data created in the memory 61 is read by the control circuit 6 and supplied to the baseband processing circuit 4.

The baseband processing circuit 4 performs, for example, processing such as error correction and channel coding as described above, and supplies this to the modulation / demodulation circuit 3. The modulation / demodulation circuit 3 modulates the signal supplied from the baseband processing circuit 4 to form a signal for transmission, and transmits the signal to the transmission circuit 23.
To supply.

The transmission circuit 23 performs processing such as amplifying the level of the signal for transmission and setting the frequency of the signal for transmission in accordance with an instruction from the frequency synthesizer 24. Then, the transmission signal adjusted by the transmission circuit 23 is supplied to the antenna 1 via the transmission / reception shared circuit 2 and transmitted from the mobile phone terminal.

Thus, in this portable telephone terminal,
Even when creating message data to be sent,
Since the display 8 has a large display area, much of the input message data can be displayed, and input processing and correction processing can be performed easily.

Since the display area of the display 8 is large as described above, the portable telephone terminal of this embodiment can use the display 8 as a vertically long display or as a horizontally long display. Can be.

FIG. 4 shows a case where the display 8 is used as a vertically long display. In this case, the display 8 is used in a state where the long sides are the vertical sides, and the display area can be widely used in the vertical direction of the display 8.

FIG. 5 shows a case where the display 8 is used as a horizontally long display. In this case, the display 8 is used in a state where the long sides are horizontal sides, and the display area can be widely used in the horizontal direction of the display 8.

As described above, the mobile phone terminal of this embodiment allows the user to set and change whether the display 8 is used vertically or horizontally in accordance with the information to be displayed. I have.

For example, as shown in FIG. 5, a personal computer is connected to the portable telephone terminal of this embodiment via a connection cord 60, and a personal computer 10 is connected.
To write the telephone number and the name corresponding to the telephone number from the address book created on the display 0 into the memory of the mobile phone terminal of this embodiment, the display 8
Can be used horizontally to display the telephone number and name supplied to the mobile phone terminal side by side.

As described above, when the display 8 is used as a horizontally long display, the information to be displayed can be more easily viewed than when the display 8 is used vertically, and the display 8 is used as a horizontally long display device. Can be used.

[Processing at the time of incoming call of portable telephone terminal] Next, as described above, the portable telephone terminal of this embodiment is capable of transmitting and receiving voice signals and transmitting and receiving data such as character data. Will be described with reference to the flowchart of FIG.

Also, the mobile phone terminal of this embodiment
A so-called answering machine mode can be set in consideration of a case where a call is received and there is a case where it is not possible to answer the call immediately.

When the answering mode is set, if an off-hook operation (response operation) is not performed even if a predetermined number of calls are made,
The mobile phone terminal according to the present embodiment automatically responds and transmits a prepared message for requesting to leave a message to the call destination because the current call cannot be answered.

When the absence mode is not set, the user of the portable telephone terminal goes off-hook or
The call is repeated until the caller goes on-hook. Also, when a call is made to this mobile phone terminal and the user performs an off-hook operation,
The mobile phone terminal is in a call mode, and a line is connected to enable a call.

In the following description, it is assumed that the absence mode described above has been set.

FIG. 6 is a flow chart for explaining a process at the time of receiving a call of the portable telephone terminal of this embodiment.
When the receiving circuit 22 detects an incoming call to the own device, it is determined whether or not the incoming call indicates that digital data such as character data is transmitted (step 101).
