<p>PROBLEM TO BE SOLVED: To enable a carrying accessor inside the device to surely deliver and receive a cartridge without making it overturn or drop. SOLUTION: A stopper 12 fitted to a tray main body 11 is turned along a cam surface part 23, and a restraining projection part 12a, which is energized to stop the cartridge when a cartridge tray 8 is in an outside access position is projected out of a set surface of the tray 8 to prevent a further interior set-in of the cartridge at the time of mounting the cartridge by the operator, and when the tray 8 is pushed into the inside access position, the projection part 12a is moved into its nonprojecting position. A lid 14 is turned along a cam surface part 24, and is in its opening position when the tray is in the outside access position, and is then moved into its closing position when the tray is pushed in. Holding members 17 are interlocked to a cam surface part 25, a cam-follower roller 19 and a link mechanism 18, and when the tray is pushed in, the cartridge is restrained on both sides by their restraining pawls 17a.</p> |
