[0001]

BACKGROUND OF THE INVENTION The present invention relates to an outdoor unit having an outdoor unit fixedly installed outside a house and at least one terminal capable of freely performing two-way wireless communication with the outdoor unit. Improvement of a wireless intercom device for enabling free communication between a visitor on the terminal side and a visitor on the terminal side,
Even if the visitor is out of the office and it is difficult to have a conversation, it is possible to make a call (communication) with the visitor, thereby ensuring security and eliminating inconvenience relating to the absence of the visitor.

[0002]

2. Description of the Related Art Conventionally, an outdoor unit is fixedly installed at a gate or the like located outside a house, and a terminal capable of making a call with the outdoor unit is installed inside the house, so that a person who is inside the house can be installed. An intercom device that allows a caller and a visitor to talk without directly meeting each other has been widely used. 2. Description of the Related Art Conventionally known general intercom devices enable communication by connecting the outdoor unit and a terminal with a cable. In addition, a device using a telephone installed in a house as the terminal device is also known and used.

[0003] However, in the case of the intercom apparatus in which the outdoor unit and the terminal are connected by a cable as described above, the work of wiring the cable is troublesome and has a poor appearance. Especially for those who live in rental housing,
Because of the obligation to restore the current situation after departure, it was not possible to easily install the intercom device using the above-mentioned cable.

In order to solve such inconveniences, a technology for making a communication between the outdoor unit and the terminal unit by wireless communication possible has been considered and widely used. In the case of such a so-called wireless type interphone device, the above-described inconvenience is solved because the cable wiring work described above is not necessary, and the interphone device has gained popularity.

[0005] In Japan, damage from so-called empty nests and the like has always been in the past, and it is necessary to ensure sufficient security in each house. In particular, in recent years, crimes called so-called picking and so-called stalking have increased sharply, and the importance of the security has been called out. A person who attempts a crime such as a burglar, picking, or stalking as described above checks whether there is a visitor in the house or is away with the intercom device. Therefore, since the above-mentioned intercom device informs the absence of the visitor, the countermeasure is urgently required.

[0006] In order to respond to the above request, for example, Japanese Patent Application Laid-Open No. 6-244787 discloses that when a visitor is away, a signal from the outdoor unit is sent to a portable telephone held by the visitor. A technology has been disclosed in which a call can be made between the outdoor unit and a mobile phone so that the user is not notified of absence. If such a technique is used, the visitor will not be aware of the absence, so that sufficient security can be achieved.

Further, Japanese Patent Application Laid-Open No. H11-298886 discloses a technique in which an image of a visitor can be displayed by the portable telephone. According to the technology described in this publication, since the image of the visitor can be confirmed, security can be further secured.

86, for example, when the visitor is in a state in which he or she is hesitant to emit a voice (for example, when a baby is sleeping and taking a walk, etc.). , When the surrounding silence should be maintained), it was meaningless. A first problem to be solved by the present invention is a case in which a visitor who is out is hesitant to speak, or a case where the visitor is a hearing impaired person. However, there is a need for security.

Furthermore, the technology described in each of the above publications enables a telephone call using a mobile telephone network, that is, it is exactly the same as a telephone call using a mobile telephone.
In this case, it is inevitable that the call cost increases. A second problem to be solved by the present invention is to make it possible to reduce the communication cost.

[0010] In addition, if the delivery is performed while the visitor is out, various inconveniences occur when the visitor goes out, for example, the deliverer must visit the house again. A third problem to be solved by the present invention is to reduce the inconvenience caused by the absence of a visitor.
