Thereafter, the pin 70 a provided on the transfer arm 70 comes into contact with the torsion spring 79. When the transfer arm 70 further rotates counterclockwise, the push arm 76 starts rotating counterclockwise as described above. Accordingly, the roller provided at the tip of the push arm 76 comes into contact with the disk 10 and starts pushing it.

Then, as shown in FIG. 11, when the motor 28 further rotates, the transfer arm 70 rotates counterclockwise, and when the gripper 74 moves away from the disk 10, it is pressed by the rotating push arm 76. As a result, the disk 10 comes to a position where it can be placed on the turntable 17 of the playback device 13. At this time, the intermittent teeth 38 of the cam 34 and the intermittent gear 6
6 is disengaged, and the clockwise side surface of the large tooth 68 a on the clockwise side of the intermittent tooth portion 68 comes into contact with the first arc portion 40. Thereafter, even if the motor 28 further rotates and the cam 34 rotates clockwise, the transfer arm 70
Is maintained at the position shown in FIG. Further, even after the motor 28 is stopped, the clockwise side surface of the clockwise large tooth 68a is in contact with the first arc portion 40,
Since the intermittent gear 66 is regulated so as not to rotate clockwise, the transfer arm 70 is maintained at the illustrated position so that the grip portion 74 does not hit the disk 10.

Now, as described above, the motor 28 is driven to move the disk 10 from the magazine 11 to the turntable 1.
The gear 46 is rotated clockwise via the worm wheel and gear under the cam 34 and the gear 44 during the transfer to the position where the gear 7 can be mounted.

The cam 48 provided integrally with the gear 46 also rotates clockwise, and when the disk 10 reaches a position where it can be mounted on the turntable 17 as shown in FIG. It comes to the position shown in (a) of the horizontal part 49c below 49 (FIG. 4). After this, the rotation of the motor 28 is continued, the cam 48 continues to rotate, and the cam follower 50 rises along the inclined portion 49c and comes to the position shown in (c) of the upper horizontal portion 49a.

As a result of the rise of the cam follower 50, as described above, the entire playback device 13 rises while being kept horizontal by the parallel crank mechanism 33, the turntable 17 of the playback device 13 receives the disk 10, and the turntable 17 further rises. And the disk clamper 35 above it
The disk 10 is clamped between the disk and the turntable 17 (the imaginary line in FIG. 3). Thus, the loading of the disk 10 ends, and the motor 28 stops.

When the disk 10 is unloaded,
The motor 28 rotates in the reverse direction from the state shown in FIG. 11, and the reproducing device 13 descends. Thereafter, while the transfer arm 70 is rotating clockwise, the gripper 74 grips the disk 10 and moves along the guide groove 82. Also, the transfer arm 70 rotates clockwise, and the pin 70a is turned into a torsion spring 70b.
When the user moves away from the position, the counterclockwise force on the push arm 76 disappears, and the push arm 76 is pulled by the spring 77 and rotates clockwise to return to the position shown in FIG.

When the grip 74 reaches the position shown in FIG.
Only the slider 114 is moved backward by the transfer arm 70, the rotation lever 86 is opened, and the disk 10 is released from the grip 74 (FIG. 7).

Thereafter, the push arm 14 rotates clockwise, and the released disk 10 is pushed into the predetermined slot 12 of the magazine 11 by the restoring force of the leaf spring 24, as shown in FIG. Return to the initial standby state. Thus, the unloading of the disk 10 ends.

The case where the loading apparatus according to the present invention is applied to a compact disk reproducing apparatus has been described above. However, the present invention is not limited to this, and can be applied to other disk-shaped recording medium reproducing apparatuses and recording apparatuses. It is possible to apply.

[0076]
