It is well known that a disc-shaped disc (optical disc) such as D) records a large amount of information signals such as voice information, image information, and character information by converting them into a plurality of minute pit rows. Then, the user mounts the disc on the disc playing device, and the optical pickup picks up the reproducing surface (or recording surface).
By reproducing (or recording), information signals such as voice information, image information, and character information can be quickly reproduced (or recorded) from a desired position, which is very pleasing to the user.

In the above-mentioned disc playing device, a disc storing magazine containing a plurality of discs is inserted into a magazine placing portion in the automatic disc playing device, and a desired disc is selectively selected up to the disc playing portion. FIG. 25 shows a conventional disc storage magazine and a disc automatic playing device which are constructed so as to be pulled out and automatically played.

In FIG. 25, a conventional disk storage magazine 200 (hereinafter referred to as magazine 200) has a box-shaped appearance. Further, in the magazine 200, the tray 201 is detachable by being guided by the left and right guide grooves 200b, 200b from the opening 200a, and the tray 201 on which the disc 202 is mounted is predetermined for each set. Are stacked with a space between. This magazine 200 is inserted from the insertion opening 210a of the automatic disk playing device 210 in the direction of the arrow, and the magazine placing section 21 is inserted.
Place at 0b. Then, the tray 20 on which the desired disk 202 is placed by the tray pull-out means (not shown).

The set of trays 201 pulled out above 11 is lowered in the direction of the turntable by a tray vertical movement means (not shown), and only the disc 202 is turned on the turntable 211.
The disc 201 is placed on the disc, the tray 201 is retracted below the turntable, and the disc 202 is played by the optical pickup 212.

[0005]

By the way, in the conventional magazine 200, after placing the magazine 200 on the magazine placing portion 210b in the automatic disc playing device 210, the tray 201 on which the desired disc 202 is placed is played. The optical pickup 2 is selectively pulled out to the portion 210c and only the disc 202 is placed on the turntable 211.
Although the disc 202 can be automatically played by 12, the magazine placing portion 210b for placing the magazine 200 and the disc playing portion 210c for playing the disc 202 are set at different adjacent positions in the device 210.

That is, the disc playing portion 210c is installed at a position where the tray 201 is completely pulled out from the magazine 200, and requires an area substantially equal to the area occupied by the magazine placing portion 210b. Therefore,
Even if the external dimensions of the magazine 200 are set to be large enough to accommodate the disc 202, the area occupied by the device 210 must be at least twice the area occupied by the magazine 200. There is a problem that it is difficult to reduce the size of the adopted automatic disk playing device 210. Further, since the magazine 200 is formed in a box and is guided by the guide grooves 200b and 200b so as to be easily pulled out of the internal tray 201 and stacked at a predetermined interval, the height of the magazine 200 is reduced. It is getting higher and the portability is decreasing. Further, since the turntable 211 and the optical pickup 212 are fixedly installed on the disc playing portion 210c in the automatic disc playing device 210, there is a problem that the tray 201 must be pulled out from the magazine 200.

Therefore, there is a demand for a disc storage magazine which can be set to have a small occupied area on the device 210 side and has a structure with good portability, and an automatic disc playing device to which the disc storage magazine can be applied.
