Problems solved by technology

[0011] However, the above-mentioned joints and protrusions are provided for the purpose of positioning the tray and the turntable. However, since the driving mechanism is a running part, it can be said that it is not necessarily at the set position. The objects are between each other, so there is a problem that it is difficult to obtain positioning accuracy

Abstract

In a disk apparatus, a movable-base position sensing switch (169) is provided such that the sensing switch is turned from ON state into OFF state at a time a turntable (20) of a movable base (13) is separated from a clamper (16) during movement of the movable base (13) to an unclamped position. A motor (91) is controlled (190,191,S12-S20) so that a driving force of the motor is used. The motor is actuated in a first direction to move the movable base to the unclamped position for a first period from the time the position sensing switch is turned into OFF state. The motor is actuated in a reverse direction for a second period from an end of the first period. The driving of the motor is stopped for a third period from an end of the second period. The motor is actuated in the first direction from an end of the third period such that the tray is moved to the disk-change position.

Description

technical field [0001] The present invention relates to a disk device, and more particularly, to a disk device having a tray-type disk loading mechanism. Background technique [0002] Generally, the disk loading operation in a disk device (such as a CD-ROM device) is roughly divided into (1) the operation of pulling the tray loaded with the disk into the disk device body and (2) the operation of pulling the tray into the disk device body. The operation for the disk to be held on the turntable (specifically, the operation for clamping between the turntable and the clamp member) is performed. These operations are performed by a motor. However, in response to recent demands for miniaturization of disk drives, various configurations in which the operations (1) and (2) are performed by a single motor have been proposed. As an example of such a disk device, there is a device disclosed in Japanese Patent Application Laid-Open No. 7-282512. [0003] In the disk device disclosed in...
