Abstract

PURPOSE:To reduce the size, the weight and the cost of a disk device by ejecting a disk-shaped recording medium by using effectively a disk driving motor. CONSTITUTION:In case of the ejection in an arrow a' direction, an auto-eject device 16 drives the disk driving motor 7 according to an eject instruct signal so as to rotate in the reverse direction of a positive rotation at the time of the recording and the reproducing of the disk 1, and drives a gear 17 at the lower part of a disk table 5, i.e., an eject driving body so as to rotate reversely in the arrow b' direction, and establishes an eject mode. At that time, a friction clutch 45 with a clutch plate 44 to be rotated and energized according to the positive or the reverse rotation of the gear 17 is provided at the lower surface of the gear 17. The clutch plate 44, rotated and energized in the arrow b' direction by the reverse rotation drive of the gear 17 in the arrow b' direction, pushes and presses one end 19a of a lever 19, i.e., a trigger member in the arrow b' direction, and the other end 19b pushes and presses the arm 22a of an eject mechanism 21. Thus, the disk device can be made small, light and low-cost.
