摘要： PURPOSE:To fix a floppy disk medium onto a spindle without any eccentricity by providing a cone which press contacts a collet from above the medium loading surface of the spindle as well in order to press the collet against the spindle while pinching the floppy disk medium against. CONSTITUTION:The cone 3 presses against the collet 2 at the part A of the collect 2 and the part B of the cone above the medium loading surface. Consequently, when a guide shaft 7 is lowered, contact points which are separated by a spring 4 in the beginning contact each other by further lowering the guide shaft 7 after the medium 1 and collet 2 contact each other. When the shaft 7 is further lowered in this state, the collet 2 is pressed by the cone 3 and pressed to spread outward. Finally, the collet 2 contacts the internal wall of the spindle 8 and the shaft 7 is further lowered in this state to flex a medium pressure spring 5, thereby securing normal medium pressure.

摘要： PURPOSE:To enable accurate discrimination by arranging a reflection type sensor to detect a specified surface of a cartridge and a control section to judge the surface detected by an output of the reflection type sensor. CONSTITUTION:When an optical disc cartridge is held with a cartridge holding mechanism 110, a reflection type sensor 11 recognizes that a surface B is detected, for example, when a cut of a shutter opener, formed on the surface B of the optical disc cartridge is detected. As compared with a sensor using a mechanical bar, the reflection type sensor can detect a cut part accurately thereby improving detection accuracy. But both of the two reflection type sensors are not ready for detection or already ready for detection, a library control section 10 directs a swivel motor control part 14 and a theta control part 15 sequentially to control the driving of a motor 112 for horizontal rotation, a rising/lowering motor 111 and a motor 12 by a fixed value separately thereby accomplishing a correction of the surfaces A and B accurately.
