Description

drive

State of the art

The invention is based on a drive according to the preamble of the main claim.

Drives for storage disks with a loading device for transporting a storage disk into the drive, the loading device comprising a carrier for receiving the storage disk, are already known. The carrier is designed, for example, as a drawer that moves out of the drive for loading the storage disk.

Advantages of the invention

The drive according to the invention with the features of the main claim has the advantage that the means only protrude from the drive in an extended position. In this way, means designed as a drawer-shaped carrier can be used to load the

Storage disk does not have to be removed from the drive. Rather, the storage plate can be inserted directly into the drive, as in a roller feed, without the storage plate, as is customary in the case of roller feeding, becoming dirty or damaged. By the Direct insertion for the user eliminates further operations for loading the storage disk, such as pressing a button, so that the drive according to the invention can be used particularly advantageously in automobiles in which the user controlling the vehicle is to be distracted as little as possible from the traffic.

The loading device of the drive according to the invention is also less susceptible to inserted small parts. With comparatively little design effort, the wear of the loading device of the drive according to the invention and of the storage disks transported with this loading device is considerably reduced.

Advantageous further developments and improvements of the drive specified in the main claim are possible through the measures listed in the subclaims.

It is particularly advantageous that the means in the region of the opening comprise two elastically supported centering elements, the spacing of which is less than the diameter of a first storage plate, an insertion of the first storage plate via the insertion opening and the opening pushing the centering elements apart on the means, and that the means on a side facing away from the opening comprise at least one holding element for blocking an inserted first storage disk. In this way, the storage disk is securely gripped by means of the centering elements and placed on the means in a defined position. Thus, the storage plate can be inserted exactly into the

Play position are spent. This prevents charging errors. It is particularly advantageous that the means comprise an edge which forms an arcuate boundary between each of the two centering elements and the at least one holding element. In this way, so-called shape compact disks can be formed

Storage disks are held centrally by the means and brought into a defined play position with the means. By definition, at least three points of the contour of these shape compact disks lie on a circle that corresponds to the outer edge of conventional compact disks, so that the shape compact disks are positioned at least over these three points by means of the circular connections on the center.

It is also particularly advantageous that the means comprise a recess which forms a receptacle for storing a second storage disk with a smaller diameter than the first storage disk. In this way, storage disks with a smaller diameter than those provided for conventional compact disks can also be held centrally by the means and in this way brought into a defined play position by the means.

Due to the deepening, such smaller storage disks can also be positively positioned on the means.

It is also advantageous that the extension of the means in the direction of insertion is approximately two thirds of the diameter of the first storage disk. In this way, the user does not have to completely insert the first storage disk into the drive, but is already completely grasped by the means when the first storage disk still protrudes from the drive with a third of its diameter. It is also advantageous that the drive in about a half of the extent of the means in

The direction of insertion, starting from the loading position of the means, is arranged away from the insertion opening and comes into engagement with the means. In this way, the means can be moved both into the play position and into the eject position with the least possible design effort.

It is particularly advantageous that the charging device comprises at least one sensor that detects a storage disk inserted on the means. In this way, the storage disk can be automatically drawn into the play position by means of the means, which does not require any further user activity and is therefore particularly convenient for the user.

A particularly simple implementation of such a sensor, utilizing the existing drive, consists in that a first sensor is designed as a pressure sensor and that the first sensor is connected to the drive and detects a force in the insertion direction on the means and thus on the drive is exercised.

It is also particularly advantageous that the charging device comprises a charging switch and that when the charging switch is actuated, the charging device brings the means from the loading position into an extension position in which the means protrude from the insertion opening. In this way, storage disks with a smaller diameter than usual can be placed on the media and transported through the media into the playback position. Another advantage is that the means in the extended position protrude approximately half from the insertion opening. In this way, a particularly wide extension of the storage disk from the drive is possible, which enables the user to conveniently remove the storage disk.

It is also advantageous that the loading device moves the means from the eject position to the loading position when the at least one sensor detects the removal of a storage disk previously placed on the means. In this way, the means can be automatically returned to the drive, which does not require any further user action and is therefore particularly convenient for the user to operate.

This advantage also arises if the

Loading device the funds after a predetermined

Brings time from the eject position to the play position.

Another advantage is that when the loading switch is actuated, the loading device brings the means from the extended position to the playback position. In this way, storage disks with a smaller diameter than usual can be transferred from the medium into the

Play position are transported, even if they can not be detected by the at least one sensor as placed on the means, especially if they were placed on the means in the eject position, without exerting any pressure in the direction of insertion on the drive or the storage disk due to their small size could be recognized by an optical sensor in the drive or on the media. drawing

Description of the embodiment

In FIG. 1, 1 denotes a drive for storage disks 5, 10, 135. The drive 1 can be, for example, a compact disc player, a compact disc changer, a mini disc player, a DVD player (digital versatile disk), a CD-ROM drive or act like that. The drive 1 comprises a loading device 15 for transporting a storage disk 5, 10, 135 into the drive 1 or out of the drive 1. The loading device 15 in turn comprises, for example, means 20 designed as carriers for receiving the storage disk 5, 10, 135. In the following it should be assumed as an example that the drive 1 is a compact disc player. According to FIG. 1, the loading device 15 comprises a first guide rail 70 and a second guide rail 75 which, for example, as a linear guide in the insertion direction 65 in the

Drive 1 run and in which the carrier 20 is guided. Of course, only a single guide rail or more than two guide rails can be provided in the drive 1 for this purpose. The carrier 20 is transported in the guide rails 70, 75 by means of a drive 80, which can be designed, for example, as a linear drive. A linear drive is, for example, a spindle drive, a belt drive, a toothed rack drive, toothed belt or the like.

Figure 1 shows the carrier 20 in a loading position. It is provided that the carrier 20 does not essentially protrude from an insertion opening 25 of the drive 1 in the loading position, but ideally rests completely within the drive 1. As shown in FIG. 1, a front edge 100 of the carrier 20 can terminate with a front edge 105 of the drive 1 which has the insertion opening 25. In the direction of the insertion opening 25, the carrier 20 comprises an opening 1000 for inserting the storage plate 5, 10, 135.

The carrier 20 described here by way of example is designed in the form of a drawer. However, it can also comprise simple and less material-consuming only a left and a right bracket or hook, between which the storage plate 5, 10, 135 is clamped. The brackets or hooks are driven synchronously by means of the linear drive, for example, or displaced individually or together in another manner known to the person skilled in the art. The brackets or hooks also form an opening in the direction of the insertion opening 25 for inserting the storage plate 5, 10, 135.

According to FIG. 1, two centering elements 30, 35 can additionally be arranged on the front edge 100 in the region of the opening 1000 of the carrier 20 and can be accessed via the insertion opening 25 and the opening 1000. The distance between the two centering elements 30, 35 is less than the diameter of a first storage disk 5, which in this example is intended to form a conventional compact disc. The centering elements 30, 35 are elastically supported on the carrier 20. According to FIG. 1, a first holding element 40 and a second holding element 45 are arranged on a rear edge 110 of the carrier 20 opposite the front edge 100 of the carrier 20. It can also be provided to arrange only a single holding element or more than two holding elements on the rear edge 110 of the carrier 20.

If the first storage plate 5 is now inserted into the drive 1 via the insertion opening 25 and the carrier 20 is in the loading position according to FIG. 1, the first storage plate 5 first presses the centering elements 30, 35 apart and in this way reaches a defined one Position on the carrier 20. The insertion process is ended when the first storage plate 5 strikes the first holding element 40 and / or the second holding element 45.

The centering elements 30, 35 and the holding elements 40, 45 ensure that the first storage plate 5 comes to rest in a defined position on the carrier 20 and can therefore also be brought into a defined play position to avoid centering errors to avoid the clamping or when positioning the first storage disk 5.

The positioning of the first storage plate 5 on the carrier 20 can additionally be improved by arranging a first circular-shaped boundary 50 on the carrier 20 between the first centering element 30 and the first holding element 40. Correspondingly, a second circular-arc-shaped boundary 55 can be arranged on the carrier 20 between the second centering element 35 and the second holding element 45. The radius of the arcuate boundaries 50, 55 corresponds approximately to the radius of the first storage plate 5.

The circular-shaped boundaries 50, 55 are particularly advantageous if, instead of the first storage disk 5, a so-called shape compact disc 135 shown in FIG. 6 is to be inserted into the drive 1 via the insertion opening 25. Such a compact shape disc 135 has the property that by definition at least three points of its contour lie on a circle whose radius corresponds to the radius of the first storage disk 5. Thus, if the centering elements 30, 35 are not detected or pressed apart when such a shape compact disc 135 is inserted, the shape compact disc 135 can generally be attached to the shape of the shape of the shape compact disc 135 by abutting at least some of the defined points Circular arc-shaped boundaries 50, 55 are placed in a defined position on the carrier 20 and brought into a defined playing position by the latter.

According to FIG. 1, it can be provided that the extension of the carrier 20 in the insertion direction 65 is less than the diameter of the first storage plate 5. The extension of the carrier 20 in the insertion direction 65 can be for example, be about two thirds of the diameter of the first storage disk 5, as indicated in FIG. 1. This means that after the first storage plate 5 has been inserted into the carrier 20 up to the stop on the holding elements 40, 45, the first storage plate 5 still protrudes from the insertion opening 25 by approximately one third of its diameter, so that the user does not excessively remove the first storage plate 5 must slide far into the drive 1 so that the first storage disk 5 can be brought into the play position. This is for the

User particularly comfortable, especially when the drive 1 is to be used in a motor vehicle and the user should be distracted as little as possible from the traffic. The distance between the centering elements 30, 35 from the holding elements 40, 45 can be chosen so that after the first storage plate 5 has been fully inserted into the carrier 20, i. H. after the first storage plate 5 stops on the holding elements 40, 45, the centering elements 30, 35 return to their starting position.

It can now also be provided, as indicated in FIG. 1, that the drive 80 at a distance of approximately half the extent of the carrier 20 in the insertion direction 65, starting from the loading position of the carrier 20, from the

Insert opening 25 is arranged in the drive 1 and comes into engagement with the carrier 20. The carrier 20 can thus always remain in direct engagement with the drive 80, both when it is in the play position in the drive 1 and when it is in the extended position from the

Drive 1 is moved out. This can be seen in Figure 2 for the play position and in Figure 3 for the eject position. According to FIG. 1, it can now be provided that the charging device 15 comprises at least one sensor 85, 90, which detects whether a storage disk has been inserted on the carrier 20. In this case, a first sensor 85 can be provided, which is designed as a pressure sensor and with which

Drive 80 is connected in such a way that it detects when a force is exerted in the insertion direction 65 on the carrier 20 and thus on the drive 80. This is interpreted to mean that a storage disk has been inserted into the carrier 20 via the insertion opening 25.

A normal switch is also conceivable as a pressure sensor. Such a switch is activated in the extended position by the extended carrier 20. If you push the carrier 20 a little bit into the drive 1, the switch is released and the pressure is recognized.

Additionally or alternatively, a second sensor 90 can be provided, which is designed, for example, as an optical sensor and also detects whether one

Storage plate was inserted into the carrier 20 via the insertion opening 25. The optical sensor 90 can include a light source 115 and a photodiode 120. The light source 115 and the photodiode 120 are arranged on the carrier 20 such that the light emitted by the light source 115 is received by the photodiode 120 when the storage plate is not inserted in the carrier 20 and that the light beam is emitted by the photodiode 120 when the storage plate is inserted in the carrier 20 Light source 115 to the photodiode 120 is interrupted, so that the presence of the storage plate in the carrier 20 is detected in this way.

Furthermore, it can optionally be provided that the charging device 15 comprises a charging switch 95, the charging device 15 being activated after the charging switch 95 has been actuated Brings carrier 20 from the loading position into the extension position, in which the carrier 20 protrudes from the insertion opening 25. The charging switch 95 thus controls the drive 80.

In FIG. 2, the same reference symbols denote the same elements as in FIG. 1. In FIG. 2, the carrier 20 with the first storage disc 5 completely inserted into the carrier 20 is in the playback position, in which the first storage disc 5 is from a reading head (not shown in FIG. 2) can be read out by a reading device. The carrier 20 is moved from the loading position into the play position by means of the drive 80 along the guide rails 70, 75. If, as in the described example according to FIG. 1, the extent of the carrier 20 in the insertion direction 65 is approximately two thirds of the diameter of the first storage plate 5, then the first storage plate 5 lies completely in the drive 1 when it stops on the holding elements 40, 45 was inserted into the carrier 20 and moved by the carrier 20 into the drive 1 by a distance which corresponds to approximately one third of the diameter of the first storage disk 5. If the drive 80 is then positioned in the drive 1, as described for FIG. 1, then in the play position according to FIG. 2 it just engages in the carrier 20 in the region of the front edge 100 of the carrier 20, so that the carrier 20 is transported back is ensured by the drive 80 from the play position to the loading position or to the extension position.

In FIG. 3, the same reference symbols again designate the same elements as in the previously described figures. According to FIG. 3, the carrier 20 with the completely inserted first storage plate 5 is in the extended position and protrudes from the insertion opening 25 and thus from the Drive 1 out. If the first storage plate 5 is inserted into the carrier 20 as far as it will go on the holding elements 40, 45 and the extent of the carrier 20 in the insertion direction 65 is approximately two thirds of the diameter of the first storage plate 5, the first protrudes

Storage disk 5 with approximately two thirds of its diameter out of the drive 1 or out of the insertion opening 25 when the carrier 20 has been moved approximately half out of the drive 1 beyond the insertion opening 25 along the guide rails 70, 75 by means of the drive 80. In this way, the user can conveniently remove the first storage disk 5 from the drive 1. If the drive 80 is positioned in the drive 1, as described in relation to FIG. 1, then it just engages in the area of the rear edge 110 of the support 20 in the support 20 when the support 20 is in the described extended position in accordance with FIG thus ensures that the carrier 20 is transported back into the drive 1.

The carrier 20 is shown in more detail in FIG. It comprises a recess 125 in the receiving area for the storage disks 5, 10, 135. When the carrier 20, as in FIG. 2, has been brought into the play position, there is a turntable in the region of the recess 125. When the carrier 20 is used to play the inserted storage plate 5, 10, 135 is lowered, the inserted storage plate 5, 10, 135 comes into engagement with the turntable, not shown in Figure 4 and can be set in rotation by this, in order to read out by the also not shown in the figures Allow drive 1 reader. Alternatively, the turntable can also be raised in order to capture the storage disk 5, 10, 135 and set it in rotation. According to FIG. 4, it can optionally be provided to provide a recess 60 with a circular arc-shaped circumference concentrically with a support surface 130 for the first storage plate 5, which is defined by the centering elements 30, 35, the holding elements 40, 45 and optionally the circular-arc-shaped boundaries 50, 55 Diameter is smaller than the diameter of the first storage plate 5 and which serves to hold a second storage plate 10 with a smaller diameter than the first storage plate 5, as shown in FIG. 5, in the same reference numerals designating the same elements as in FIG. 4. Also in FIG 4 denote the same reference numerals as the same elements in the other figures.

The functioning of the drive 1 according to the invention is now explained in more detail in a state transition diagram according to FIG. In a first state 155 of the drive 1, the carrier 20 is in the loading position according to FIG. 1. The first state 155, that is to say the loading position of the carrier 20, can be left when a first condition 140 is fulfilled. The first condition 140 is fulfilled if at least one of the following cases occurs:

1. The first sensor 85 detects the insertion of a storage plate 5, 10, 135 into the carrier 20 via the insertion opening 25.

2. The second sensor 90 detects the insertion of a storage plate 5, 10, 135 into the carrier 20 via the insertion opening 25.

3. The charging switch 95 is actuated.

If the carrier 20 is in the loading position, then storage disks with the diameter of the first storage disk 5 are usually inserted into the slot 25 Carrier 20 inserted, ie storage disks with a conventional diameter, for. B. conventional compact discs.

If the first condition 140 is met, it is checked whether the fourth condition 170 is met. The fourth condition 170 is fulfilled if a storage disk 5, 10, 135 has been inserted in the loading position of the carrier 20. The fourth condition 170 is met in the first two cases of detection by the first sensor 85 or the second sensor 90. However, if neither the first sensor 85 nor the second sensor 90 detects a storage disk in the carrier 20 when the charging switch 95 is actuated, the fourth condition 170 is not met. If the fourth condition 170 is fulfilled, a state transition takes place to a second state 160, in which the carrier 20 is in the play position. This state transition is thus characterized in that the carrier 20 is transported from the loading position into the playback position according to FIG. 2. If the fourth condition 170 is not met, a state transition to a third takes place

State 165 takes place, in which the carrier 20 is in the extended position according to FIG. 3, so that during this state transition, the carrier 20 is transported from the loading position to the extended position. In the second state 160, the inserted storage disk 5, 10, 135 is played back. H. the data stored on it are read out by a reading device of the drive 1 and fed to a reproduction. The second state 160 is exited when the second condition 145 is fulfilled. The second condition 145 is fulfilled if at least one of the following two cases occurs:

4. The charging switch 95 is actuated.

5. A readout error when playing the disk is caused by a logic Evaluation of the read data, which is not shown in the figures, was found.

If the second condition 145 is fulfilled, a state transition from the second state 160 to the third state 165 takes place, i. H. the carrier 20 is transported from the play position to the eject position according to FIG. 3. The third state 165, i.e. H. the extension position of the carrier 20 is exited when a third condition 150 is fulfilled. The third condition 150 is met if at least one of the following four cases occurs:

6. The charging switch 95 is actuated. 7. The first sensor 85 detects the insertion of one

Storage plate 5, 10, 135 in the carrier 20th

8. The second sensor 90 detects the insertion of a storage disk 5, 10, 135 into the carrier 20.

9. A predetermined time expires after the third state 165 is reached.

If the third condition 150 is fulfilled, it is checked whether a sixth condition 175 is fulfilled. The sixth condition 175 is fulfilled if a storage disk 5, 10, 135 has been inserted in the third state 165, for example if the 7th or 8th case occurs and one of the two sensors 85, 90 has inserted a storage disk 5, 10, 135 has detected. If the sixth condition 175 is met, a state transition takes place into the second state 160 and the carrier 20 is replaced by the

Ejected position in the play position for playing the inserted disk 5, 10, 135 transported. If, in the 6th or 9th case, neither of the two sensors 85, 90 detects a storage disk 5, 10, 135 in the carrier 20, the sixth condition 175 is not fulfilled and it occurs State transition from the third state 165 to the first state 155 takes place, the carrier 20 being transported from the extended position to the loading position.

In the third state 165, that is when the carrier 20 is in the

Extending position is present, a storage plate 5, 10, 135 inserted in the carrier 20 can be removed from the carrier 20 or a storage plate 5, 10, 135 can be inserted in the carrier 20. For loading a conventional storage disk with the diameter of the first storage disk 5, the first state 155 of the drive 1, that is to say the loading position of the carrier 20, is provided according to the invention, so that loading of such a storage disk in the third state 165 is possible but not necessary. That is, to load the first storage disk 5, the carrier 20 does not have to be brought into the eject position beforehand. Rather, the ejection position of the carrier 20 serves primarily for the convenient removal of the first storage disk 5 from the carrier 20. For the second storage disk 10 and the so-called shape compact disks, which in FIG

However, it is advisable to provide the extension position of the carrier 20, that is to say the third state 165 for loading such storage disks, since otherwise a defined central insertion of such a storage disc in the loading position of the carrier 20 is not guaranteed. The ejection positions of the carrier 20 and thus the third state 165 also serve to remove the second storage plate 10 or the shape compact disc 135 from the carrier 20.

If in the third state 165 the user has removed an inserted storage disk 5, 10, 135, this removal is detected in that neither the first sensor 85 nor the second sensor 90 has an inserted storage disk detect, ie neither pressure is exerted on the pressure sensor 85, nor is the light beam from the optical sensor 90 interrupted. In this way, the sensors 85, 90 detect the removal of the storage disk 5, 10, 135 by no longer detecting an inserted storage disk. As described, this leads to the transition to the first state 155. If at least one of the two sensors 85, 90 detects an inserted storage disk 5 when the charging switch 95 is actuated or when the predetermined time in accordance with the sixth or the ninth case in the third state 165 , 10, 135 by exerting pressure on the drive 80 and thus on the pressure sensor 85 or by interrupting the light beam from the optical sensor 90, as described, a state transition from the third state 165 to the second state 160 takes place. However, if an inserted storage disk 5, 10, 135 is not detected by either of the two sensors 85, 90 when the 6th case or the 9th case occurs, a state transition from the third state 165 to the first state 155 takes place, as described. Thus, when a storage disc 5, 10, 135 is inserted in the third state 165, the carrier 20 is brought into the play position either immediately after detection of the inserted storage disc 5, 10, 135 by at least one of the two sensors 85, 90, but at the latest when the charging switch is actuated 95 or after the specified time has elapsed, provided that an inserted storage disk 5, 10, 135 is then detected by at least one of the two sensors.

The optical sensor 90 is advantageously arranged in the area of the front edge 105 of the drive 1 in the drive 1. This ensures the detection of storage disks 5, 10, 135 inserted into the carrier 20 both in the loading position and in the extending position, and, as can be seen in FIG. 2, also in the play position of the carrier 20. In particular, the insertion of Storage disks with With a smaller diameter, such as the second storage disk 10 or shape compact disks or generally shape storage disks 135 both in the loading position and in the extending position of the carrier 20, it is advantageous to also set the optical sensor 90 at approximately the same distance to arrange each of the two centering elements 30, 35.

To implement the state transitions according to FIG. 6 and to check the conditions of that shown there

State transition diagram includes the drive 1 a controller, which is not shown in the figures and to which the sensors 85, 90, the drive 80 and the charging switch 95 are connected.

According to the invention, it can be provided that the carrier 20 only protrudes from the drive 1 in the extended position.

Instead of being a carrier, the means 20 can also be designed as a roller feed, which remains in the loading position essentially, preferably completely, in the drive 1 and only protrudes from the drive 1 in the extended position in order to extend the storage plate 5, 10, 135 as far as possible Release drive 1 and thus increase the ease of use for the user.
