OPTICAL DISK UNIT

PROBLEM TO BE SOLVED: To provide an optical disk unit which has a little variation of a stopping position of a disk tray and no lateral shake of the disk tray when stopping the disk tray for ejecting and starting of insertion without incurring cost up. SOLUTION: In the optical disk unit, when the disk tray 2 is ejected before the stopping position, a switch lever 4 is pushed by a slant portion of a switch rib 50 formed on the disk tray to activate a tray out switch 3 for stopping voltage supply to a driving motor. The slant portion of the switch rib 50 is formed as a concave curved slant portion 50a to reduce variation of the stopping position of the disk tray. Moreover, lateral shake of the disk tray is prevented by shortening the length of the switch rib 50 and shifting the disk tray 2 a bit to the ejecting direction Y. COPYRIGHT: (C)2009,JPO&INPIT
