摘要： An optical disk device capable of securing a rigidity of a tray that holds an optical disk is provided. When an optical disk is put into trays stacked in a main body, a holding portion provided to the tray holds the optical disk. In this case, since the holding portion holds the optical disk from the label face side of the optical disk, a recording face located on the opposite side to the label face can be opened without provision of a notch in the tray. Accordingly, a rigidity of the tray can be secured.

摘要： There is provided an optical disk device that is capable of obtaining a required optical disk holding force uniformly and sufficiently. When information held and recorded on an optical disk is reproduced, a recording face of the optical disk is loaded on a loading portion of a clamping mechanism, then a projection portion is passed through a hollow portion of the optical disk to the label face side, and then the optical disk is held by chuck claws protruded from the projection portion. At this time, the chuck claws are turned around a supporting shaft provided along a tangential direction of the projection portion respectively to clamp the optical disk, but base end portions of the chuck claws are pushed by pushing portions provided to pushing members to have an elasticity and are turned. Therefore, even when a particular chuck claw gets caught, the pushing portions that are pushing the caught chuck claws are elastically deformed to allow the pushing members to move, so that remaining pushing portions push the base end portions of remaining chuck claws.

摘要： A disc changer apparatus includes a casing. A plurality of trays are contained in the casing for carrying discs respectively. The trays are held and arranged in a stack. A region between a designated one of the trays and a tray immediately above the designated tray is expanded. A disc on the designated tray is pushed. A region between the designated tray and the disc on the designated tray is expanded after the disc on the designated tray is pushed. A drive mechanism moves a turntable into the expanded region between the designated tray and the disc on the designated tray to place the turntable below the pushed disc. The drive mechanism includes a shaft, a base plate supported within the casing via the shaft, a damper, and a chassis connected to the base plate via the damper and carrying the turntable.
