PROBLEM TO BE SOLVED: To absorb backlashing of a tray at an ejection position without deteriorating tray slidability and without increasing a tray driving load. SOLUTION: A shaft member (41) extending along in loading and ejection direction is provided at one side of the tray (40), and a bearing (21) provided in a drive body (20) supports the shaft member (40) in a freely slidable way and holds the tray (40) in a freely loadable and ejectable way. A cam (43) projecting outward laterally is provided at the back of the other edge of the tray (40). Rollers (23) whose perimeter surfaces project outward at an ejection position of the tray (40) in front of the drive body (20), facing the cam (43) are arranged so as to make an interval between the shaft member (41) and the perimeter surfaces of the rollers (23) narrower than an interval between the shaft member (41) of the tray (40) and the projecting cam (43) to the extent of causing elastic deformation in the tray (40). The perimeter surfaces of the rollers (23) press the projecting cam (43) to thereby absorb backlashing of the tray (40) at the ejection position. COPYRIGHT: (C)2007,JPO&INPIT
