Abstract:
1. A disk device comprising: a device body; a slide tray taken in and out from the device body; a rotary tray mounted on the slide tray, the rotary tray having a plurality of disk setting sections arranged in the circumferential direction thereof; a chucking mechanism attached to the slide tray for chucking a disk set in the disk setting section at a disk scanning position, a motive gear attached to the slide tray; a gear mechanism including an engaging pin provided on the motive gear side and a Geneva gear arranged on the rotary tray and provided with a groove section to be engaged with and disengaged from this engaging pin, the gear mechanism converting continuous rotation of the motive gear into intermittent rotation of the rotary tray; a cam member having a guide pin; an endless cam groove provided in the motive gear for guiding the guide pin to reciprocate the cam member so that the chucking mechanism is changed over between a state of chucking on and a state of chucking off; a rack for taking in and out the slide tray, the rack arranged in the device body and extending in a direction of taking in and out the slide tray; a guide groove arranged in parallel with the rack; a motor; a central gear composed of a spur gear rotated by the motor, the central gear arranged on the slide tray at a position between the motive gear and the rack; a connecting member pivotally connected with a support shaft of the central gear so that the connecting member is relatively rotated; an idler gear composed of a spur gear always engaged with the central gear so that the idler gear can be selectively engaged with the motive gear or the rack when a direction of rotation of the central gear is changed over; and an engaging body for maintaining a state of engagement of the idler gear with the rack when the engaging body slides in the guide groove during taking in and out the slide tray, wherein an intermittent rotation of the rotary tray, an operation of taking in and out the slide tray and chucking on and off of the chucking mechanism during the rotary tray is stopped are conducted by power generated by the motor.
