<p>PROBLEM TO BE SOLVED: To provide a device with improved operability capable of surely holding a disk at the time of the disk loading of vertical placement. SOLUTION: Disk holding bodies 4 are provided on almost symmetrical positions across the center of the mounting recessed part 2 of a disk tray 1 and made turnable by the pivotal supporting of a bearing 5 and a holding part 4a is projected to the mounting recessed part 2 of the disk tray 1 by an energizing means 7. At the time of setting the disk D to the mounting recessed part 2, it is pushed and widened by the action of a slope S1 and the disk D is passed through. When the disk D is set to the mounting recessed part 2, the holding part 4a is turned to the state of being projected to the mounting recessed part 2 and the disk D is held by the slope S2 . When a height from the bottom surface 2a of the mounting recessed part 2 to the slope S2 is in the relation of (h+t)/2>=x, the floating of the disk D is controlled and it is prevented from moving over a side wall 2b. When it is in the relation of t>=x, the disk D is pressed to the bottom surface 2a.</p> |
