    • 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.
    • 一种光盘播放器,包括可提升地支撑在主机架1上并具有安装在其上的信号再现单元31的升降机架5和由主机架1支撑并可沿与提升机架的运动方向相交的方向移动的驱动滑动件9 驱动滑块9具有与升降机架5上的凸轮从动件接合的直的凸轮部分,用于往复驱动提升机架5.间歇进给机构设置在驱动滑动件9和马达23之间,用于使驱动器往复移动 滑动。 进给机构包括用于从马达直接接收扭矩的驱动部分和驱动部分连续旋转时由驱动部分间歇驱动的被驱动部分。 给驱动部分的动力传递到驱动滑块,从而逐步移动滑块。 驱动部分具有接合部分,当驱动滑块处于静止状态时,该啮合部分与被驱动部分接合以锁定驱动滑块,由此可以将再现单元保持在适当位置。

    • A disc player comprising a disc loading mechanism (2) for moving a tray (5) for placing a disc thereon from a disc discharge position to an intermediate position above a turntable (10) and then to a loading completed position below the intermediate position, a clamp mechanism (7) for pressing the disc into contact with the turntable (10), and signal recording-reproduction means for reproducing signals from the disc on the turntable (10) or recording signals on the disc. The clamp mechanism (7) comprises a clamp lever (71) movable toward and away from the turntable (10) with the movement of the tray (5) to thereby clamp the disc and release the disc from the clamp.
    • 一种光盘播放器,包括用于移动用于将盘放置在其上的盘从盘排出位置到盘台(10)上方的中间位置然后到中间位置下方的装载完成位置的盘(5)的盘装载机构(2) 用于按压盘与转盘(10)接触的夹紧机构(7),以及信号记录再现装置,用于从转盘(10)上的盘再现信号或在盘上记录信号。 夹紧机构(7)包括夹板(71),随着托架(5)的运动,可以朝向和远离转盘(10)移动的夹紧杆(71),从而夹紧盘并将盘从夹具中释放出来。
