支持機構。An objective lens facing the recording medium, a light emitting member that emits a detection beam to the objective lens, and a light receiving system member located on the optical axis that passes through the objective lens are held on a slider that moves along the recording medium. In the optical pickup mounted with a holder, the light-receiving system member has a light-receiving element and a cylindrical lens, and the light-receiving element is held movably with respect to the holder in a direction perpendicular to the optical axis. The cull lens is a support mechanism for the light receiving system of an optical pickup, which is held in a holder so that it can move forward and backward in the optical axis direction.
