Claims

[Scope of Claim for Utility Model Registration] 1. A leaf spring-type mounting plate for z-axis adjustment that is attached in a cantilevered manner to an opto base so as to be elastically displaceable in the z-axis direction that coincides with the optical axis incident on the optical sensor;
A z-axis direction adjusting means for adjusting the displacement of a leaf spring type mounting plate for axis adjustment in the z-axis direction, and an xy adjustment mounting plate to which an optical sensor is attached and attached to the leaf spring type mounting plate for z-axis adjustment. , the xy adjustment mounting plates are provided at one location each in two orthogonal directions passing through the center of the optical sensor;
The optical sensor is attached to the leaf spring type mounting plate for z-axis adjustment by a mounting screw that becomes a rotation center axis when adjusting the optical sensor in the What is claimed is: 1. An optical sensor mounting structure for an optical head, characterized by comprising a means for mounting an optical sensor. 2. The z-axis direction adjustment means has a groove that is formed on opposite sides of the two orthogonal directions of the mounting screws of the xy-adjustment mounting plate and engages a shaft portion of an eccentric pin for x-y adjustment. 2. The optical head according to claim 1, wherein the leaf spring type mounting plate for adjusting the z-axis direction is provided with a pin hole into which a tip end pin portion of the eccentric pin for x-y adjustment is inserted. Sensor mounting structure. 3. The z-axis direction adjustment means is characterized in that a z-axis adjustment screw in the z-axis direction that engages with the free end of the leaf spring type mounting plate for z-axis direction adjustment is screwed into the opto base. An optical sensor mounting structure for an optical head according to claim 1 or 2.
