PURPOSE:To improve the disk exchanging speed and to attain the assured actuation of an automatic disk changing device by forming many storing grooves of about 1/4 semicircle shapes to a disk storing tray, and inserting push-up grooves of a push-up mechanism in response to said storing grooves. CONSTITUTION:Many storing grooves 102 having the curvature radiuses accordant with disks and about 1/4 semicircle shapes are formed to a tray main body 103. Then parallel guide grooves 114 are provided continuously on the extended lines of grooves 102 with a prescribed pitch. Then push-up grooves 115 of a disk push-up mechanism 106 are put into a bag-shaped cut part between the grooves 102 and 114, respectively. Thus desired disks are pushed up independently of each other. Thus it is possible to load assuredly a desired one of many disks stored in a small capacity. In such a way, the disk exchanging speed is improved and the assured actuation of an automatic disk changing device is attained. |
