Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a disk device equipped with the disk insertion detecting mechanism of an optical detection system, capable of detecting the disk of a high light transmittance without complicating a structure. SOLUTION: When a disk 20 is inserted, and it reaches the position of a conveyor roller 6, the conveyor roller 6 is pressed downward by the disk 20, and a guide rail unit 1 is rotated around a rotary shaft 7 in an arrow direction. Thus, as the axis of a light from an emission element 2 is shifted, and a light from the emission element 2 is blocked by a slit plate 10, that is detected by a light receiving element 3, and the rotation of a loading motor is started. The conveyor roller 6 is rotated by the rotation of the loading motor, and the disk 20 is moved into the device. COPYRIGHT: (C)2005,JPO&NCIPI
