Abstract

PURPOSE:To reduce an external size and to contrive the miniaturization and the reduction in weight of a supporting structure by arranging a disk in a housing position and a disk in reproducing position so as to overlap. CONSTITUTION:Plural sets of trays 14 are arranged in many steps up and down in a tray case 5 and the trays can slides to the front side or the right side of the tray case 5 by a specified guiding body. In this state, a disk 9 moves reciprocally between a waiting position in the tray case 5 and the position of a chuck board 33 by a specified loading mechanism. In this time, the tray 14 taken out on the chuck board position is supported so as to overlap with the tray 14 in the waiting position partly in a plane view. Consequently, the external size of a cabinet 1 is smaller than the width of two disks.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention records, for example, music or video by converting it into a digital signal, records the recorded disc on a turntable, and records information on both sides or one side of the disc. The present invention relates to a disc player that reproduces information. Therefore, the disc player referred to in this specification includes a disc device dedicated to recording.

[0002]

2. Description of the Related Art Conventionally, there has been a technique of providing a plurality of trays on which discs are placed and selectively reproducing the discs in each tray.

[0003]

SUMMARY OF THE INVENTION In the prior art, the width of at least two discs is required to secure the tray standby position for accommodating each disc and the position for reproducing the discs. There was a problem that it could not be easily reduced.

[0004]

SUMMARY OF THE INVENTION However, according to the present invention, in a disc player in which a plurality of trays on which discs are placed are stacked and supported in multiple stages, the trays taken out at the reproduction position are partially overlapped with the trays at the standby position. It is characterized in that it is configured to support.Since the disc at the storage position and the disc at the reproduction position are arranged so as to overlap each other, it is possible to easily reduce the outer width dimension required for storing and reproducing a plurality of discs. In addition, it is possible to easily reduce the size and weight of the disc support structure.
