The other buttons 5 are connected to a signal determination circuit, and the display tube is connected to a display circuit (not shown), and the operations of both buttons are controlled by a microcomputer (not shown).

Next, the operation will be explained. When playing the disc 58, when the disc is pressed against the door 9 in the state shown in FIG. 2, the door link end 120 turns on the sensor 121. As a result, the plunger 13 is attracted by the control circuit, the drive motor 19 starts rotating at the same time as the door 9 is opened, the drive gear 23 and the dog boo 9108 rotate counterclockwise, and the bell) 11
3. The small pulley 112 rotates the transfer roller 83 in the disk retraction direction. At this time, the rack 27 is the plunger 1
3 and clutch slider 16. The clutch link 30 is disengaged from the drive gear (state in FIG. 7).

Subsequently, the disk 58 is retracted and the sensor 118 is illuminated (then the drive motor 19 stops).

Plunger 13 is turned off. This causes the spring 170
The force closes the door 9. In addition, the rack 27 rotates and lifts the clutch link 30 by the force of the spring 15, and the drive gear 2
3 (state in Figure 8). Next, the control circuit (all of the circuits described above) causes the drive motor 19 to rotate in reverse, causing the drive gear 23 to rotate clockwise.

At this time, even if the drive gear 23 is reversed, the large pulley 111 does not push the convex portion 107 within a certain rotational angle range with its long length 108, so no power is transmitted and the large pulley does not rotate. Therefore, the transfer roller 83 does not rotate. The rack 27 moves forward and moves to a position where it overcomes the rack holder 32 (. After that, the elongated hole 25 pushes the right slide arm 24. From K, the right slide arm 24 starts moving forward, and the kite arm 41 also rotates. As a result, the left slide arm 46 also moves forward at the same time.Subsequently, the bushing cam 104 rises and the positioning lever 103 rises (the state shown in Fig. 9).
.

Since the lifting levers 52 and 54 are lowered, the clamp arm 90 is lowered, and the disc uke 87 is also lowered by the force of the spring 106. Also, since the simultaneous pressing roller 84 is lowered, the disc 58 is lowered, and the front positioning bin 102 and the side wall of the disc uke in the left and right direction, the bin 116 in the rear direction,
117, it is lowered in a substantially positioned state and placed on the turntable 60. At this time, the front end 34 of the right slide arm pushes up the stopper link 37, lowers the door stopper 35, and locks the door 9 so that it cannot be opened. At the same time, the clamper 80 presses down the disk 58.

Lower surface parts 99, 10 of left and right slide arms 24, 46
0.

Since the unit plate 101 is removed from the bins 98, 97, and 96, the unit plate 75 is released from its fixation and becomes IJ-1m.

Subsequently, the bent portion 49 of the left slide arm 46 presses the chuck switch 50 (Fig. 10), so that the drive motor 1
9 stops, the disk installation is completed, and then the control circuit turns the turntable 60. The state in which the pickup 62 becomes operational and starts playing (FIG. 11).

Next, a description will be given of when to stop the performance and take out the disc 58. When the eject button 3 is pressed, the control circuit stops the turntable 60, rotates the drive motor 19, and rotates the drive gear 23 counterclockwise. The rack 27 begins to move rearward, and the left and right slide arms 24 and 46 begin to move rearward. Next, the lower surface parts 99 and 100
, 101 contact the bins 98° 97, 96, and fix the unit plate 75 so that it does not move upward. Furthermore, the raising levers 52 and 54 are connected to the left and right slide arms 24 and 46.
When the clamp arm 90 moves upward, the clamp arm 90 is pushed up.

The clamper leaves the disc 58. At the same time, the door stopper 35 is raised by the force of the spring 380.

Subsequently, as the clamp arm 90 rises, the disc uke 87 comes into contact with the chassis, and the clamper is lifted until it touches the bottom surface of the case 1, so the disc 58 is lifted up from the turntable 60.
The pressure roller and spring 106 press the disk 58 against the transfer roller (as shown in FIG. 12).

Subsequently, the bushing cam 104 is pushed down by the left slide arm 46 and the 0 positioning lever 103 is lowered. Furthermore, the rack 27 moves rearward to a position away from the rack holder 32. This rear bent portion 48 is the up switch 47
Press. The drive motor 19 is stopped by the control circuit, and the plunger 13 is simultaneously turned on. As a result, the door 9 opens and the clutch slider 16 moves rearward against the springs 15 and 17.

The clutch link 30 is rotated, the rack 27 is rotated downward, and the drive gear 23 is disconnected. Subsequently, the drive motor 19 rotates in reverse, the drive gear 23 rotates clockwise,
Dog pulley 111. Bell) 113. The transfer roller 83 rotates the disk 58 in the ejection direction via the small pulley 112,
Eject the disc 58.

When the disk 58 passes the sensor 119, the control circuit stops the drive motor 19. At this time, the plunger 13 is turned off and the door is closed.

Further, in this embodiment, the plunger 13 is turned off at this time, but the plunger 13 remains on, and when the disk moves away from the sensor 11B, the plunger 13 is turned off.
It is obvious that it is easy to configure the door to be closed by turning 3 off, and in this way the door can be prevented from hitting the disc during ejection.

〔Effect of the invention〕

According to the invention. when the disc is lowered. After the disk is prevented from moving forward by the positioning bin before the retention is released. By lowering the disc while releasing its hold, it is possible to securely attach the disc to the turntable even under vibration conditions such as when mounted in a car or when the device is placed at an angle, thereby eliminating malfunctions. There is a similar effect when rising. Also,
Even when the transfer roller is used for raising and lowering, the disk can be positioned with a simple structure, so it is also economically effective.

Next, the operation will be explained. When playing the disc 58, when the disc is pressed against the door 9 in the state shown in FIG. 2, the door link end 120 turns on the sensor 121. As a result, the control circuit causes the plunger 15 to suction the door 9.
At the same time as opening, the drive motor 19 starts rotating, the drive gear 23 and the large pulley 111 rotate counterclockwise, and the bell)
115', the small pulley 112 rotates the 9 feed roller 83 in the disk retraction direction. At this time, the rack 27 is disengaged from the drive gear 25 by the plunger 15, clutch slider 16, and clutch link 50 (state in FIG. 7). Subsequently, the disc 58 is retracted and when the sensor 118 is no longer illuminated, the drive motor 19 is stopped and the plunger 13 is turned off. This causes spring 17
The door 9 is closed by the force of. And the rack 27 is the spring 15
The force causes the clutch link 50 to rotate and rise and engage the drive gear 23 (state in Fig. 8), and then the control circuit (all the circuits described above) causes the drive motor 19 to rotate in the reverse direction and the drive gear 23
rotates clockwise. At this time, even if the drive gear 23 reverses, the large pulley 111 does not rotate because the rotation angle range of the elongated hole 108 does not push the convex portion 107, so no power is transmitted, and the large pulley does not rotate. Therefore, the transfer roller 83 does not rotate once. The rack 27 moves forward to a position where it overcomes the rack stopper 3z. After that, the long hole 25 is the right slide arm 2.
Press 4. As a result, the right slide arm 24 starts moving forward, and the rotating plate 41 also rotates, so that the left slide arm 46 also moves forward at the same time. When pressed, the cam 1o4 rises and the positioning/lever 103 rises (
(Situation shown in Figure 9). As the lifting levers 52 and 54 rotate, the clamp arm 90 is lowered, and the disk receiver 87 is also lowered by the force of the spring 10. At the same time, the crimp row 284 descends, so
58 is lowered, and the front positioning pin 102
The left and right sides are the side walls of the disc receiver 87, and the rear side is the pin I.
It is lowered in a substantially positioned state by L6, 117 and placed on the turntable 59. At this time, the front end 34 of the right slide arm pushes up the stopper link 57, lowers the door stopper 55, and locks the door 9 so that it does not open. At the same time, the clamper 80. Hold down the disc 58 and move the left and right slide arms 24°4
The lower surface parts 99, 100, 101 of 6 are pins 9B, 97
．． Since it is separated from 96, the unit plate is released from its fixation and becomes free. Next, the end 50 of the left slide arm 46 presses the chuck switch 49 (FIG. 10), so the drive motor 19 stops and the disk loading is completed.
After that, the control circuit controls the turntable 60. The pickup 62 becomes operational and starts playing (No. 11: state shown in the figure). Next, we will explain when to stop playing and take out the 5th disc. When the eject button 3 is pressed, the turntable 60 is stopped by the control circuit, the drive motor 19 is rotated, the drive gear 25 is rotated counterclockwise, the music rack 27 starts moving backward, and the left and right slide arms 24, 46 begins to move backwards. Next, the lower surface parts 99, 100, 101
Is it a pin? 8.? 7 and 96 to fix the unit plate 75 so that it does not move upward. Sara. When the lift levers 52 and 54 rotate with the movement of the left and right slide arms 24° 46, the clamp arm 9° is pushed up and the clamper 8o is separated from the disk 58. At the same time, the door stopper 65 is raised by the force of the spring 38. Subsequently, as the clamp arm 9o rises, the disk receiver 87 moves to the clamp 7/(the tip of the holder 82 comes into contact with the chassis 8, the clamper 80 is lifted, the disk 58 is lifted from the turntable 6o, and the pressure roller 84 is pressed against the spring 106. to press the disk 58 against the transfer roller (the state shown in FIG. 12).Then, the bushing cam 104 is pushed down by the left slide arm 46, lowering the positioning lever 103.Furthermore, it moves backward to a position away from the rack holder 32.After this, The end 48 presses the up switch 47. The control circuit stops the drive motor 19 and at the same time the plunger 1
5 is turned on. As a result, the door 9 opens and the clutch slider 16 moves rearward against the springs 15 and 17.
The clutch link 50 is rotated, and the rack 27 is rotated downward and disconnected from the drive gear 23. Subsequently, the drive motor 19 rotates in reverse and drives. The gear 23 rotates clockwise, and the large boom IJ111. Bell) 113. The transfer row 283 rotates through the small pulley 112 in the direction of ejection of the ice sheet, and the disk 58 is ejected. When the disk 58 passes the sensor 119, the control circuit stops the drive motor 19. At this time, the plunger 13 is turned off and the door is closed. In this embodiment, the plunger 13 is turned OFF at this time, but the plunger 13 is kept ON, and when the disk moves away from the sensor 11B, the plunger 13 is turned OFF and the door is closed. It is obvious that the configuration is easy, and in this way the door can be prevented from hitting the disc during ejection. [Effects of the Invention] According to the present invention, the positioning pin prevents the disk from moving in the forward direction before releasing the holding when the disk is lowered, and then the disk is lowered while releasing the holding of the disk. This allows the device to be reliably attached to the turntable even under vibration conditions such as when mounted on a vehicle or when the device is placed on an incline, which has the effect of eliminating malfunctions, and also has the same effect when the device is raised. Further, even when only one transfer roller is used for lifting and lowering, the disk can be positioned with a simple structure, which is highly economical. 4.
