Abstract:
1. An optical disk device comprising: a main chassis; a disk tray movable in a direction protruding from said main chassis and in the opposite direction so as to carry said optical disk in or out of said main chassis; a turntable that rotates said optical disk carried-in by said disk tray; a traverse chassis that supports said turntable, said traverse chassis being supported by said main chassis so that said traverse chassis is swingable between a holding position in which said turntable is able to hold said optical disk and a retracting position retracting from said holding position; an optical pickup that performs recording or reproducing of a signal on said optical disk rotated by said turntable; a common motor that generates a driving force for feeding said optical pickup, for swinging said traverse chassis, and for moving said disk tray; a first gear that rotates by a driving force of said motor; a second gear that rotates by transmission of rotation from said first gear; a rack portion integrally formed with said optical pickup, said rack portion engaging said first gear to move, an engagement between said rack portion and said first gear being released when said rack portion reaches a predetermined engagement-releasing area; a slide rack relatively movable with respect to said rack portion, said slide rack engaging said first gear to move; a slider member having an engaging portion capable of engaging said second gear and a cam portion that causes said traverse chassis to swing between said holding position and said retracting position; and a trigger member that moves in conjunction with said slide rack in a state where said engagement between said rack portion and said first gear is released, so as to move said slider member to a position in which said slider member engages said second gear, wherein said first gear and said second gear have the same number of teeth, and the rotation is transmitted from said first gear to said second gear so that the ratio of the number of rotations of said first gear to the number of rotations of said second gear is 1:1.
