PROBLEM TO BE SOLVED: To simply detect an operating condition of a disk changer device with an inexpensive configuration. SOLUTION: A crank arm 7 is rotated by drive force of a drive motor 5. The fore-end 71a of the crank arm 7 is connected to a tray 1. When the crank arm 7 rotates, the tray 1 is opened/closed. Three rib sections 74 to 76 are provided on the tracks formed on the bottom surface of a rotating section 70 of the crank arm 7 in a concentric circular manner and three microswitches 94 to 96 are provided on a control substrate 9 so that the three microswitches 94 to 96 are opposing to the three rib sections 74 to 76. The microswitches 94 to 96 abut to the rib sections 74 to 76 by the rotation of the crank arm 7 and the on/off states of the switches are changed. Rotational positions of the crank arm 7 are detected by the combination of the on/off states of the three microswitches 94 to 96. COPYRIGHT: (C)2005,JPO&NCIPI
