<p>PROBLEM TO BE SOLVED: To miniaturize a device and to make the device light weight and to reduce the cost of the device by providing a clutch unit selectively transmitting the power of the driving motor provided in a housing to a tray driving unit and an optical pickup transferring unit. SOLUTION: A pinion 51 and a first gear 60 are revolved by the operation of a driving motor 50 and a disk tray 20 is inserted in a housing 1 being in the direction of the arrow A1 with a first rack part 211. As a result, a sliding member 100 is moved in a projected direction from the housing 1 through respective engagements between a second rack part 212 and a gear part 91 and the gear part 91 and a first clutching part 101 by this movement. A gear member 90 is revolved in the direction of the arrow R1 in the cource of this movement to more move the disk tray 20 and the engagement between the first rack 211 and the first gear 60 is released to stop the disk tray 20 and an inserting movement is completed. Even after the completion of the inserting movement, the operation of the driving motor is continued and, thus, an optical pickup 30 slid.</p> |
