A holder 103' is mounted on which a positioning lever 106 having a positioning lever 102, which is arranged slightly apart from the outer diameter of the disk so as to prevent the disc from shifting in the forward direction, is pivotally supported so as to be movable up and down. Also, positioning lever 1
05 is placed below the bushing cam 104 which is pivotally supported by the chassis 18, and the cam surface 105 of the bushing cam 104 is fitted into the pin of the left slide arm 46 to restrict its rotation. Further, the disk receiver 87 is always urged toward the unit plate 75 by two springs 106IC. It also has an elongated hole 108 so as to be rotatable within a certain angular range with respect to the convex portion 107 of the drive gear. A belt 113 is placed between small pulleys 112 that rotate the roller 86 by friction transmission.

Further, the transfer roller 83 and the pressure roller 84 are made of rubber or the like, and rotation is transmitted between the cores 114 and 115 by friction to prevent scratches when the disk is fixed.

In addition, the unit plate 75 is equipped with bins 116 and 117 at a position concentrically above the center of the turntable 59 and slightly larger than the outer diameter of the disk, and also mounted on the chassis 8 at a similar distance just below the outer diameter. A photoelectronic sensor 118 that detects the presence or absence of light is provided.A sensor 119 that detects when the disk is inserted approximately half way through the door 9 is also provided. A sensor 121 is provided to detect the position of , and is connected to a signal judgment circuit (not shown) made up of a microcomputer along with the aforementioned sensor 118 , TJP switch 47 , and chuck switch 49 . The motor 19, the pickup 62, and the plunger 16 are connected to a drive circuit (not shown), the eject button 3, the play button 4, and the other buttons 5 are connected to a signal determination circuit, and the display tube is connected to a display circuit (not shown). The operations of all of them are controlled by a microcomputer (not shown).

Let me briefly explain the operation. When playing the disc 58, press the door 9 with the disc in the state shown in FIG. 6 to turn on the door link end 120 or the sensor 121. As a result, the plunger 15 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 26 and the large pulley 111 rotate counterclockwise, and the bell) 11
3. The small pulley 112 rotates the transfer roller 85 in the disk retraction direction. At this time, the rack 27
6, the clutch slider 16, and the clutch link 30 are disengaged from the drive gear 2'5 (state in FIG. 8). When the disk 58 is pulled in and the sensor 118 no longer emits light, the drive motor 19 is turned off. It stops, and the plunger 13 becomes OFF'F. As a result, the door 9 is closed by the force of the spring 17. Further, the clutch link 30 of the rack 27 rotates and rises due to the force of the spring 15, and engages with the drive gear 25 (state in FIG. 9). Next, the control circuit (all of the circuits described above) causes the drive motor 19 to rotate in reverse, causing the drive gear 26 to rotate clockwise. Note that even if the drive gear 23 reverses the rotation of the extra thick pulley 111, the rotation angle range of the elongated hole 108 is within the convex portion 1.
Since 07 is not pressed, power is not transmitted and the large boob does not rotate. Therefore, the transfer roller 85 does not rotate. The rack 27 moves forward and moves over the rack stopper 32 to a position. After that, the elongated hole 25 pushes the right slide arm 24. 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. Next, Butushukam 10
4 is raised and positioned, and the 5 bar 103 is raised (state shown in FIG. 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 106. At the same time, since the pressure roller 84 descends,
The disk 58 is lowered, and the front side positioning bin 102 and the side wall C of the disk receiver 87 in the left and right direction are aligned with the bin 11 in the rear direction.
6, 117, it is lowered in a substantially positioned state and placed on the turntable 59. Further, the front end portion 54 of this unique slide arm pushes up the strave link 37, lowers the door stopper 65, and locks the door 9 so that it cannot be opened.

At the same time, the clamper 80 presses down the discs 5-8,
Lower surfaces 99, 100 of left and right slide arms 24, 46,
Since the unit plate 101 is separated from the bins 98, 97, and 96, the unit plate 75 is released from its fixation and becomes free. Next, the end 50 of the left slide arm 46 presses the chuck switch 49 (Fig. 11), so the drive motor 19 stops, disk loading is completed, and then the control circuit puts the turntable 60° pickup 62 into operation. Start playing (state shown in Figure 11).

Next, a description will be given of when to stop the performance and take out the disc 5B. 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 26 is rotated counterclockwise, the rack 27 begins to move backward, and the left and right seven ride arms 24 .46 start moving backwards. Lower surface parts 99, 100, 10
1 contacts the bins 98, 97, and 96, and fixes 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 2.
When rotating with the movement of 4 and 46, the clamp arm 9
0 is pushed up and the clamper 80 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 90 rises, the disk receiver 87 brings the tip of the clamper holder 82 into contact with the chassis 8, and the clamper 80 is held.

The disk 58 is lifted up from the turntable 60, and the pressure roller 84 presses the disk 58 against the transfer roller by the spring 106 (the state shown in FIG. 13).

Subsequently, the bushing cam 104 is pushed down by the left slide arm 46, and the positioning lever 103 is lowered. Furthermore, the rack 27 moves rearward to a position away from the rack holder 32. This rear end portion 48 presses the up switch 47. The drive motor 19 is stopped by the control circuit, and at the same time, the plunger 16 is turned on. This opens the door 9, moves the clutch slider 16 backward against the springs 15 and 17, moves the clutch link 3o seven times, rotates the rack 27 downward, and disconnects it from the drive gear 23. Subsequently, the drive motor 19 rotates in the reverse direction, and the drive gear 25 rotates clockwise, resulting in a wide rotation. The transfer roller 86 rotates in the disk ejecting direction via the small pulley 112, and 58 disks are 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.

Further, in this embodiment, the plunger 13 is turned OFF at this time, but the plunger 15 is left ON, and when the disk moves away from the sensor 118, the plunger 13 is turned OFF.
It is obvious that it is easy to configure the door to be closed by turning off the disc 3, and in this way the door can be prevented from hitting the disc during ejection.

〔Effect of the invention〕

According to the present invention, since the pressure roller is provided on the side of the vibration isolation section, a constant distance is maintained between the disk and the pressure roller even if the vibration isolation section vibrates in any direction, thereby preventing damage to the Dinuk. There is a possible effect.

The pressure roller can be moved up and down simply by moving the clamp arm up and down, and when a disk is inserted, it can be reliably positioned relative to the insertion hole, making the mechanism simple and economically effective.
