Abstract

A disc player comprising a lift chassis 5 liftably supported on a main chassis 1 and having a signal reproduction unit 31 mounted thereon, and a drive slide 9 supported by the main chassis 1 and movable in a direction intersecting the direction of movement of the lift chassis 5. The drive slide 9 has a straight cam portion in engagement with a cam follower on the lift chassis 5 for reciprocatingly driving the lift chassis 5. An intermittent feed mechanism is provided between the drive slide 9 and a motor 23 for reciprocatingly moving the drive slide. The feed mechanism comprises a drive portion for receiving a torque directly from the motor, and a driven portion to be intermittently driven by the drive portion while the drive portion is in continuous rotation. The power given to the driven portion is delivered to the drive slide to thereby move the slide stepwise. The drive portion has an engaging portion which, while the drive slide is at rest, engages with the driven portion to lock the drive slide, whereby the reproduction unit can be held properly in position.
