To provide a 'disk device' that does not waste a power during waiting for disk insertion and thus can save power consumption. The disk device includes: a casing equipped with an insertion port to which a disk is inserted; a conveying mechanism for conveying a disk, which is provided inside the insertion port; a switching type detecting switch that is switched to a detection state in accordance with a movement force of a disk inserted from the insertion port in an insertion direction; and an optical detecting member that is switched to a detection state when a disk inserted from the insertion port blocks an optical path, wherein when the detecting switch is switched to a detection state, power supply to the optical detecting member is started.

Disk device

A shutter member is provided so as to be capable of moving in association with a roller bracket. The shutter member rotates by a predetermined range in association with the rotation of the roller bracket, and then a projection of the shutter member is pressed in a Y1 direction by a shutter pressing portion provided on the right side slider. Accordingly, the shutter member is rotated clockwise, and an opening and closing panel portion of the shutter member closes an insertion port from the inside thereof. Therefore, the insertion port is closed reliably by the shutter member, so that insertion of another disc from the insertion port into the interior of the apparatus while the disc is rotating is prevented.

The positioning member includes an abutment abutting against the outer periphery of the disc and a regulatory portion extending farther toward the slot than the abutment and is supported on either one component of the drive chassis and the clamper-supporting member, and the regulatory portion abuts against the other component.

Disc-positioning mechanism for car-mounted disc player

A car-mounted disc player with an elastically supported drive unit including a turntable and a pickup; a clamper-supporting member rotatably supporting a clamper; a clamp mechanism for activating the clamper-supporting member to move toward or away from the drive unit so as to clamp or unclamp a disc between the turntable and the clamper; a lock mechanism for bringing the drive unit in a locked state or an unlocked state with respect to the chassis; and a change-over mechanism for activating the clamp and lock mechanisms. During change-over operations of the change-over mechanism for activating the clamp and lock mechanisms, the change-over mechanism can be halted at a half-locked position where the drive unit is brought in the locked state while the disc is kept in a clamped state by the turntable and the clamper.

Car-mounted disc player

A disc device in which a clamping member for supporting a clamper is pushed against a supporting portion by a holding elastic member. At the side opposite the supporting portion, a clamping elastic member is provided between a drive chassis and the clamping member. The distance from a supporting fulcrum to a portion upon which the elastic force of the clamping elastic member acts is greater than the distance from the supporting fulcrum to a portion upon which a clamping force acts, so that the elastic force of the clamping elastic member for setting the clamping force can be small. Therefore, a large localized force does not act upon the clamping member from the clamping elastic member. In a conventional vehicle-mounted disc device, a spring having a large elastic force is used to exert a clamping force to clamp a disc by a clamper. Therefore, a large localized force acts on a clamping member for supporting the clamper. In addition, a large force is required to lift the clamping member. The present invention solves these problems.

Disc device

A head feeding mechanism which includes a screw shaft adapted to rotate in the normal and reverse directions using a motor as a drive source, a nut member engaged with the screw shaft, and a spring member connected to a head and adapted to elastically press the nut member against the screw shaft and which causes the head to reciprocate in the thrust direction of the screw shaft through the intermediation of the nut member through rotation of the screw shaft. The nut member has a substantially cylindrical female screw engaged with a male screw of the screw shaft, and the nut member is elastically biased in both the radial direction and the thrust direction of the screw shaft by the spring member. In this construction, if the elastic biasing force in the radial direction of the spring member holding the nut member in pressing contact with the screw shaft is set small, the female screw of the nut member does not move over the male screw of the screw shaft, so that a small torque suffices for the motor rotating the screw shaft, which is effective in achieving a reduction in the size of the motor and the entire head feeding mechanism including the motor. Further, the thrust play of the nut member due to backlash is removed, making it possible to prevent a malfunction attributable to external vibration, such as a dropout.
