PURPOSE:To simplify a clamper moving mechanism, by operating the clamper moving mechanism in accordance with a moving mechanism which moves a disc in the direction orthogonal to a disc engaging face of a rotary base. CONSTITUTION:When a cartridge 3 is pressed in, the back face of the cartridge 3 presses a rise part 25a of a slide material 25, and the slide material 25 is moved right against a spring 45, and finally, a roller 24 drops onto a substrate 46 from the slide material 25. That is, since a rotary material 14 is always deviated clockwise by a spring 15, the rotary material 14 is turned with a shaft 10 as the fulcrum when the downward position restriction due to the slide material 25 is released. Then, a cartridge holding material 18 is displaced together with the cartridge 3 in the direction orthognoal to the disc engaging face of a disc rotary base 36. The cartridge 3 is placed on a cartridge receiving base 55, and a positioning pin 50 is inserted to a hole 5 of the cartridge 3. |
