項記載の移動光学系駆動装置。[Claims for Utility Model Registration] 1. A deflection mirror that deflects a laser beam emitted from a fixed optical system fixed to a housing on the main body side by 90 degrees, and a laser beam deflected by this deflection mirror that is incident on a recording medium. A guide mechanism, a moving coil fixed to the actuator base, a permanent magnet attached to a support along the moving direction of the actuator base, and the moving A moving optical system drive for an optical head that moves and travels along the radial direction of the recording medium by a linear motor mechanism consisting of a yoke shaft inserted into a coil and attached to a support along the permanent magnet. In the device, the guide mechanism includes a yoke roller rotatably attached to the actuator base so as to roll on the yoke shaft, and a V provided on the housing along the moving direction of the actuator base.
A moving optical system drive device comprising a V-shaped roller rotatably attached to an actuator base so as to rotate while being engaged and guided by a groove. 2. Utility model registration claim 1, wherein the V-shaped groove is constituted by a gap formed between a pair of guide shafts having a substantially round cross section and fixed together.
The moving optical system drive device described in 2.
