<p>A disc device is provided with a tray (2), a slide member (22), a rib arm (3) and an arm shifting cam mechanism (4), i.e., a rib arm shifting means. Before a shutter (62) closes, the arm shifting cam mechanism (4) shifts the rib arm (3) to a retracting position where the rib arm is not in contact with the shutter (62) by a sliding member (22), and when the shutter (62) is open, the arm shifting cam mechanism brings the rib arm (3) into contact with the tray side of a cartridge rib (61b) by a slide member (22) and shifts the cartridge rib (61b) to a pressing position where the cartridge rib is pressed from the tray side.</p> |
