Claims (1)

[Claims for Utility Model Registration] A disk arranging member that is rotatably provided and has a plurality of disk arranging portions, in which disks serving as recording media are individually arranged, and this disk arranging member. a disk placement member driving means for rotating the disk placement member; a disk placement portion identification portion formed on the disk placement member for identifying each disk placement portion; and a disk placement portion identification portion for detecting the disk placement portion identification portion. a disk placement part detection means; a braking means operation identification part formed corresponding to each disk placement part;
Based on the braking means operation detecting means for detecting the braking means operation identification part, the braking means for braking the rotating disk arrangement member, the output of the disk arrangement part detection means, and the output of the braking means operation detection means,
When the selected disk placement portion is detected, the driving force applied to the disk placement member from the disk placement member driving means is released, and the disk placement portion is placed at a predetermined stop position. and a control means for controlling the operation of the braking means, wherein a plurality of the above-mentioned braking means operation identification parts are formed,
The control means applies a braking force to the disc arrangement member a plurality of times according to the number of each braking means operation identification section based on the output of the braking means operation detection means that detects each braking means operation identification section, and selects one of the brake means operation identification sections. 1. A disc playback device, characterized in that the disc playback device is configured to control a braking means so that the disc placement section is placed at a predetermined stop position.
