摘要： PURPOSE:To improve the number of contained pieces of a disk in small capacity, and to display the number of disk containing groove positions by forming in one body many tray leaves as a laminated layer, and providing continuously a guide piece which has a separable thin-walled part and is used for displaying a disk containing groove position, on each tray leaf. CONSTITUTION:A tray lead body 202C which has been formed in one body is structure by laminating that which has been divided and formed in advance at every disk containing groove unit. In this case, each tray leaf 202A forms a disk containing groove between partition walls 208 of each adjacent tray leaf 202A at the time of lamination. Also, in order to prevent the backlash of a disk contained in the disk containing groove, an elastic projecting piece 202D is formed on each partition wall 208A. Moreover, in each tray leaf 202A, in order to facilitate the case when the number of disk containing groove positions of the time of laminating the leaves in one body is displayed, for instance, at every ten pieces, a guide piece 202E having a thin wall part which can be separated easily by an external force is formed on the upper end of the rear part of each partition wall 208A.
