Patent ID: 8429680

Claim:
A disk device comprising: a disk conveyance mechanism which conveys a disk to a replayable position; a disk installment mechanism which installs the disk conveyed to the replayable position onto a turntable so as to bring the disk into a replayable clamping state; a drive source which generates drive force driving the disk conveyance mechanism and the disk installment mechanism; and a transmission route switching mechanism which switches a transmission route of the drive force so that the drive force generated by the drive source is transmitted to the disk conveyance mechanism or the disk installment mechanism, wherein the disk installment mechanism has: a drive gear rotated by transmitting the drive force generated by the drive source; a slide cam member having a rack to be meshed with the drive gear, the slide cam member being moved by rotating the drive gear in a state that the drive gear and the rack are meshed with each other; and a buffer portion which is able to relatively move the rack at least starting to mesh with the drive gear in an opposite direction with respect to a moving direction of the slide cam member moved by conveyance of the disk, when the disk is conveyed to the replayable position by the disk conveyance mechanism and the slide cam member moves so that the drive gear and the rack are meshed with each other.
