Connecting means is configured to connect the

Next, the operation of the embodiment will be explained using FIGS. 4a to 5f and 5a to 5c.

First, in the disk storage state, that is, the storage state of the disk mounting table 9 in the set main body, as shown in FIG.
The mounting table 9 and the pull-out auxiliary body 13 are in a layered state as shown in FIG. It is located behind the position.

When the mounting table 9 is pulled out to attach or detach the disk 11, the motor 16 drives the gears 17 and 1.
8 rotates counterclockwise, as shown in Figure b.
First, the mounting table 9 is moved forward via the upper rack 12 meshed with the upper gear 17. At this time, the lower gear 18 also rotates together with the upper gear 17, but since the lower rack 15 is located behind the meshing position with the lower gear 18, the two do not mesh.
The auxiliary body 13 remains stationary.

Next, the movement of the mounting table 9 progresses and the upper rack 1
2 reaches the position where it separates from the upper gear 17, from then on, the mounting table 9 is not directly moved forward by the upper gear 17, but as shown in FIG. The convex part 19a of the cam body 19, which is rotating together with the cam body 18, sequentially contacts one end 21a of the lock lever 21 led out from the square hole 20 of the mounting table 9 from its smooth surface, and gradually rotates the lock lever 21 clockwise. Operate rotation.

Therefore, when the lever 21 is rotated, one end of the lever 21 becomes 21a as shown in FIG.
comes into contact with the front edge of the square hole 20, and the other end 21
b leads out from the square hole 20 and is located on the front side of the front edge of the connecting piece 25 in the auxiliary body 13.

Further, when the lever 21 is rotated by the convex portion 19a of the cam body 19, the mounting table 9 further moves forward via the one end 21a of the lever 21 and the front edge of the square hole 20, and the projection 26 of the mounting table 9 moves forward. touches the rear edge of the connecting piece 25 to move the auxiliary body 13 forward, and as shown in FIG.
The lower rack 15 of the auxiliary body 13 comes to mesh with the lower gear 18 immediately before it is separated from one end 21a of the auxiliary body 13.

Then, due to the subsequent rotation of both gears 17 and 18, the auxiliary body 13 moves forward via the lower rack 15 meshing with the lower gear 18, and at this time, as shown in FIG. Since the front edge presses the front edge of the square hole 20 via the lever 21, the mounting table 9 also moves forward in accordance with the forward movement of the auxiliary body 13, and the mounting table 9 is pulled out. When the withdrawal of this auxiliary body 13 is completed,
A position detection switch or the like detects that the mounting table 9 or the auxiliary body 13 has reached its drawing completion position, and this signal causes the motor 16 to stop.

In this way, the disk mounting table 9 having a short depth can be pulled out to the front of the set main body without changing the pull-out distance from the conventional one. At this time, the rear part of the mounting table 9 is supported by the auxiliary body 13, and this auxiliary body 1
3 is supported by a support stand 10 within the set main body, sufficient hanging space for the mounting table 9 having a small depth dimension is ensured, and the disk 11 can be stably attached and detached.

Next, a case will be described in which the disk 11 is attached to and removed from the table 9 that has been pulled out and the table 9 is stored.

In this case, the motor 16 drives both gears 17,
18 rotates clockwise, firstly, the drawer auxiliary body 13 moves rearward via the lower rack 15 meshing with the lower gear 18, and at this time, as shown in FIG. Since the rear edge of the connecting piece 25 presses the protrusion 26 rearward, the mounting table 9 also moves rearward together with the auxiliary body 13. During this operation, the other end 21b of the lock lever 21 comes off the connecting piece 25, sinks into the square hole 20 under the bias of the spring 23, and comes into contact with the stopper 24.

As this operation progresses and the lower rack 15 separates from the lower gear 18, as shown in FIG.
The convex portion 19a of the cam body 19, which is rotating clockwise together with the gears 17 and 18, comes into contact with one end of the lock lever 21, and the rotation of the cam body 19 causes the mounting table 9 to be moved via the lever 21 and the stopper 24. Moving further rearward, the upper rack 12 of the mounting table 9 comes to mesh with the upper gear 17, as shown in FIG.

Therefore, by the subsequent rotation of the upper gear 17, the mounting table 9 is moved rearward via the upper rack 12, and the mounting table 9 is housed in the set body.

In addition, in the above embodiment, the disk mounting tables 9 and 1
The drawer auxiliary bodies 13 of the stages are sent out in order and placed on the mounting table 9.
However, it is also possible to provide two or several stages of drawer auxiliary bodies 13 and to draw out the mounting table 9 by sequentially drawing out each stage.

[Effect of idea]

As described above, according to the disk pull-out device of this invention, the disk mounting base is movably supported by the pull-out auxiliary body that is movable parallel to the pull-out direction, and the pull-out auxiliary body is assisted immediately after the feeding by the feeding means of the disk mounting base is completed. The disc mounting table is connected to the disk mounting table, and the drawing auxiliary body is sent out by the feeding means, and the disc mounting table is pulled out to a position where the disk can be attached and removed, so that the disk mounting table has a hanging space unlike the conventional one. Even without it, the pull-out auxiliary body can support the mounting table when it is pulled out and support against the force applied when attaching and detaching the disk.
The dimensions of the disk mounting base in the pull-out direction can be reduced, and since the pull-out auxiliary body is provided parallel to the disk mounting base and can normally be kept in a stacked state, the device can be expanded without changing the pull-out distance of the disk mounting base. The overall dimension in the pull-out direction can be reduced, and a disk player equipped with this type of disk pull-out device can be made smaller.
