    • A mechanism for adjusting the position of a pickup used in a disc player. The mechanism includes a slider which is driven along a path in the radial direction of a turntable. The slider has a projection which serves as the origin of angular movement. An adjustment plate is mounted on the slider and has the pickup mounted thereon. The adjustment plate is movable in a direction perpendicular to the radial direction of the turntable. A plurality of tension springs are provided between the slider and the adjustment plate to bias the plate against one of a plurality of side walls of the slider. The tension springs further bias a lower surface of the adjustment plate against the projection. In this manner, the optical axis of an objective lens of the pickup passes through the origin of angular movement. A tracking adjustment device is mounted on the slider for angularly moving the adjustment plate to adjust the inclination of the pickup in a tracking direction. A tangential adjustment device is mounted on the slider for angularly moving the adjustment plate to adjust the inclination of the pickup in a tangential direction. Further, a centering adjustment device is provided on the one side wall for moving the adjustment plate to adjust the centering of the pickup.
    • 一种用于调节在盘播放器中使用的拾取器的位置的机构。 该机构包括沿着转台的径向的路径驱动的滑块。 滑块具有作为角运动原点的突出部。 调节板安装在滑块上并安装有拾取器。 调节板可以在与转盘的径向垂直的方向上移动。 在滑块和调节板之间设置有多个拉伸弹簧,以将板抵靠滑块的多个侧壁中的一个侧壁。 拉伸弹簧进一步使调整板的下表面偏压突起。 以这种方式,拾取器的物镜的光轴穿过角运动的原点。 跟踪调节装置安装在滑块上,用于角度地移动调节板以调节拾取器在跟踪方向上的倾斜度。 切向调节装置安装在滑块上,用于角度地移动调节板,以便在切向方向上调整拾取器的倾斜度。 此外,在一个侧壁上设置定心调节装置,用于移动调节板以调节拾取器的定心。

    • A slider controller for a disk player including a slider which supports an optical pickup and which is driven by a linear motor. The linear motor for moving the slider is supported on an auxiliary chassis. The auxiliary chassis is swingably mounted with respect to a main chassis of the disk player so that the optical axis of an information reading light beam emitted from the pickup can be adjusted to keep the axis perpendicular with respect to the surface of the disk. The slider controller further includes a pushing cam, a locking plate and a drive member. Upon operation of the drive member, the pushing cam is moved by the drive member to push a contact surface of the locking plate such that a locking portion of the locking plate is engaged with the slider during a stoppage mode of the disk player. Therefore, the slider is locked by the locking plate despite the adjustment of the inclination of the slider.
    • 一种用于盘播放器的滑块控制器,其包括支撑光学拾取器并由线性电动机驱动的滑块。 用于移动滑块的直线电机支撑在辅助机箱上。 辅助底盘相对于盘播放器的主机架可摆动地安装,使得可以调节从拾取器发射的信息读取光束的光轴,以使轴线相对于盘的表面保持垂直。 滑块控制器还包括推动凸轮,锁定板和驱动构件。 在驱动部件运行时,推动凸轮由驱动部件移动,以推动锁定板的接触表面,使得锁定板的锁定部分在磁盘播放器的停止模式期间与滑块接合。 因此,尽管调节滑块的倾斜度,滑块被锁定板锁定。
