PURPOSE:To perform the positioning of a disk, by securing a shift of a disk storing part between the position of the opening side and the position of the performance side, preventing the shift of the disk when the coincidence is obtained between the center of the disk and the center of a disk driving mechanism and shifting only the disk storing part. CONSTITUTION:A storing part 3 storing a disk D is shifted by a motor 19 between the opening side position and the performance side position. The part 3 goes horizontally at first and then moves down obliquely by means of a pin 14 interlocking a guide groove 15 provided on the side wall of a case 1 and a pin 16 interlocking a guide groove (not shown in the diagram) at the opposite side to the pin 14. When the part 3 reaches the performance position, the disk D touches a large diameter part of a positioning pin 25 and stops its shift. Thus only the part 3 moves down furthermore. The disk D is held between a driving disk 21 and a holding disk 22 and set in the performance state. In such way, the accurate positioning is possible for the disk. |
