DISCLOSURE OF THE INVENTION The present invention relates to means for a disc changer for achieving the above-mentioned object, and relates to a flat plate tray in which cabinets are accommodated in parallel and disks are placed, and the trays are arranged in parallel. A disc player provided on the end side in the thickness direction of the accommodated tray, and a movement which is provided on one side of the tray and is pulled out from the accommodation position and placed and moved toward the disc player Means, and an opening / closing means that is provided in a cabinet on the side of the tray opposite to the moving means, and is capable of pulling out the tray from the cabinet.

[0007]

According to the disc changer of the present invention, since the opening / closing means for pulling out the tray is provided in the cabinet on the side opposite to the moving means, the tray can be pulled out easily by opening the opening / closing means. The disks mounted on the tray can be easily replaced.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 are views showing an embodiment of a disc changer according to the present invention, for example, a so-called karaoke disc changer using a disc such as a video disc or a compact disc.

This disc changer has a compact disc player 2 accommodated in the uppermost stage and a video disc player 3 accommodated in the lowermost stage in a cabinet 1, and the compact disc player 2 and the video disc player 3 are accommodated.
, And flat plate-shaped trays 4 on which a compact disc or a video disc is placed are accommodated in parallel.
It is mounted so that it can slide in the front-back direction.

A door 5 which is an opening / closing means shown in FIG. 2 is attached to the cabinet 1 on the front side of the tray 4 so as to be openable and closable. By opening the door 5, the tray 4 is attached to one side of the tray 4. The video disc or the compact disc that is pulled out to the front side and placed on the front side without being affected by the elevator 7 of the moving means that is also the tray selecting means installed on the rear side is replaced. You can

In the tray 4 selecting means, four upper and lower guide rails 6 are erected on the rear surface side of the tray 4 at four positions in the front, rear, left and right. The guide rails 6 keep the elevator 7 horizontal. It is mounted so that it can move up and down.

As shown in FIG. 3, on the lower surface side of the elevator 7, two gears 8 that mesh with the racks 6a provided on each of the guide rails 6 are provided on two shafts 9, respectively. Worm gears 10 fixed to each of the shafts 9 are two worms 1 fixed to one shaft 11.
2 and the upper and lower sides thereof mesh with each other, so that the shafts 9 rotate in directions opposite to each other, as shown in FIG.

A worm gear 13 is fixed to the shaft 11. The worm gear 13 meshes with a worm 15 fixed to a motor 14, and when the motor 14 rotates, all the gears 8 move at the same speed and move to the front side. It rotates in the opposite direction to the rear side, and this rotation causes the elevator 7 to move in the vertical direction while maintaining the level.

As shown in FIG. 4, a screw shaft 19 rotated by a worm gear 18 meshing with the worm 17 of the motor 16 is rotatably supported on the upper surface of the elevator 7. The tip is hooked 20a
5, 6 of the pull-in lever 20 which has become
The nut 20b shown in is screwed.

The tray 4 is provided with the pull-in lever 2
An engaging groove 4a that engages with the hooking portion 20a of 0 is formed. When the elevator 7 moves up and down, the hooking portion 20a comes into engagement with the engaging groove 4a from above and below, and the selected tray 4 When the position at which the hooking portion 20a is engaged with the engaging groove 4a is reached, the elevator 7 is stopped at that position by stopping the motor 14.

When this stop is performed, the motor 16 starts to rotate, and the screw shaft 19 is rotated, so that the pull-in lever 2
0 is moved to the lower right side of FIG.
The tray 4 of the engaging groove 4a in the engaged state is moved accordingly and is accommodated in the rail grooves 21 provided on both the left and right sides of the elevator 7.

When this accommodation is completed, the rotation of the motor 16 is stopped, and then the motor 14 starts to rotate again, so that the elevator 7 is moved upward if the disc mounted on the tray 4 is a compact disc. In the case of a video disc, the disc 14 is rotated so as to be moved downward, and when the movement to a predetermined position is completed, the motor 14 is also stopped, and the disc on the tray 4 is stored in the compact disc player 2 by a conventionally known means. Alternatively, it is transferred to the video disc player 3.

Thus, the required disc is selected, the compact disc player 2 or the video disc player 3 plays the selected disc, and when the performance is finished, the next disc is selected. Then, the disc is returned from the player to the tray 4 by the operation opposite to the transfer.

Then, when the motor 14 rotates in the opposite direction to the original position where the tray 4 placed on the elevator 7 is pulled out, the rotation of the motor 14 is stopped and the elevator 7 is stopped. Is stopped, the motor 16 rotates in the opposite direction to the above, the tray 4 is pushed by the pull-in lever 20, and the tray 4 is returned to the original position.

After the completion of this returning operation, the disc to be reproduced next is selected and the compact disc player 2 and the video disc player 3 are operated in the same manner as the above selection.
The disc changer selects a required disc and reproduces it as described above.

Therefore, it is easy to replace the disk accommodated in the disk changer, it takes a long time to replace the disk, and the customer is not required to wait.

[0022]

As described above, according to the present invention, the opening / closing means capable of pulling out the tray is provided in the cabinet on the side opposite to the moving means for pulling out the tray and transferring the disk mounted on the tray to the player. Therefore, when the opening / closing means is opened, the tray can be pulled out without being disturbed by the moving means, and the disc mounted on the tray can be replaced very easily.
