Is very enjoyable, and there is no need to provide a separate disk playing place in the device 20 as in the prior art, and the occupied area on the device 20 side can be set small, contributing to the miniaturization of the device 20. Therefore, the disk automatic performance device 20 can be applied to, for example, a vehicle.

[0116]

According to the disk storage magazine according to the present invention described in detail above, the tray on which the disk is mounted is densely stacked on the tray mounting table, and the slidable magazine slide plate has a plurality of trays and tray mounting. Since the frame is integrally formed so as to be portable while partially surrounding the outer periphery of the mounting table, the height of the disk storage magazine can be made ultra-thin, and the carrying performance is improved, thereby improving the user's performance. For example, when the automatic disk playing device is applied to a vehicle, the carrying of the disk storage magazine becomes convenient. Further, when the magazine slide plate in the disk storage magazine reaches the first and second positions, the disk storage magazine can be set in a portable state, and the disk can be attached or detached at the first position of the magazine slide plate. Since the disc is restricted and the disc can be attached and detached at the second position of the magazine slide plate, the user can safely operate the disc. Further, when the magazine slide plate reaches the third position, a desired tray can be selected and separated at that position. Therefore, this disk storage magazine is applied to an automatic disk playing device. In this case, for example, it is possible to face a component for playing the disc between the separated trays, so that the disc can be played at the place where the disc storage magazine is mounted, so that a separate place for playing the disc is provided. This eliminates the necessity, so that the occupied area on the device side can be set small, which is advantageous in that it can contribute to downsizing of the device.
