ABSTRACT:
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.
