Abstract
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.
Claims28
A car-mounted disc player comprising:
- a drive unit elastically supported on a chassis having an elastic member between the drive unit and the chassis, the drive unit including a turntable and a pickup;
- a clamper-supporting member rotatably supporting a clamper;
- a clamp mechanism operable to activate the clamper-supporting member to bring a disc in a clamped state or an unclamped state between the turntable and the clamper;
- a lock mechanism operable to place the drive unit in a locked state or an unlocked state with respect to the chassis;
- and
- a change-over mechanism operable to activate the clamp mechanism and the lock mechanism,
- wherein the change-over mechanism may 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.
A car-mounted disc player comprising:
- a drive unit elastically supported on a chassis having an elastic member between the drive unit and the chassis, the drive unit including a turntable and a pickup;
- a clamper-supporting member rotatably supporting a clamper;
- a clamp mechanism operable to activate the clamper-supporting member to bring a disc in a clamped state or an unclamped state between the turntable and the clamper;
- a lock mechanism operable to place the drive unit in a locked state or an unlocked state with respect to the chassis;
- and
- at least one slide member movably supported on the chassis and operable to activate the clamp mechanism and the lock mechanism,
- wherein during a movement of the slide member for activating the clamp mechanism and the lock mechanism, the slide member may stop at a half-locked position.
A car-mounted disc player comprising:
- a drive unit elastically supported on a chassis having an elastic member between the drive unit and the chassis, the drive unit including a turntable and a pickup;
- a clamper-supporting member rotatably supporting a clamper;
- a clamp mechanism operable to activate the clamper-supporting member to place a disc in a clamped state or an unclamped state between the turntable and the clamper;
- a lock mechanism operable to place the drive unit in a locked state or an unlocked state with respect to the chassis;
- at least one slide member, movably supported on the chassis, operable to activate the clamp mechanism and the lock mechanism in accordance with its back-and-forth movement;
- and
- position-detecting means operable to detect when the slide member reaches to a half-locked position,
- wherein the position detecting means may stop slide member at the half-locked position.
