PURPOSE:To minimize the size of the device, by constituting the device so that the guide part member of disc cartridge may lower at the specified position after it moves forwards to the disc cartridge insertion direction, and so that the plate part member equipped with disc clamp part may freely moves up and down. CONSTITUTION:When a disc cartridge 15 is inserted to a guide part member 17, it touches with a stopper 41 and the motion is stopped. When the disc cartridge 15 is still pressed towards the insertion direction, the guide part member 17 begins to move leftward resisting a spring device 40, and the plate part member 16 gradually moves down along the ring outline of cam surfaces 32, 33 and guided by vertical long holes 30, 31 of chassis side. Further when the disc cartridge is still pressed, the plate part member moves downward until the lowest points of cam surfaces 32, 33, and at this position roller pins 38, 38 reach the corner part of cone hole 39, 39, and then the guide part member 17 becomes mono-block with plate part member, and rapidly sinks down completing the loading. |
