ACTUATOR-ASSEMBLING TOOL FOR OPTICAL PICKUP, ACTUATOR-ASSEMBLING METHOD FOR OPTICAL PICKUP, ACTUATOR FOR OPTICAL PICKUP, AND ACTUATOR-ASSEMBLING ACCURACY INSPECTING METHOD FOR OPTICAL PICKUP

摘要

PROBLEM TO BE SOLVED: To suppress reduction of tilt accuracy of a moving part and a supporting part caused by a tool 5a when an actuator for optical pickup having the moving part and the supporting part is assembled.;SOLUTION: The actuator for optical pickup is assembled so that a moving part reference plane being a reference of an assembling position of the moving part in the direction being parallel to an optical axis of an objective lens and a supporting part reference plane being reference of an assembling position of the supporting part are positioned on the same flat plane. When they are assembled, the moving part is mounted on the tool 5a so that the moving part reference plane contacts with an installation plane 51 on the tool 5a, and the supporting part is mounted on the tool 5a so that the supporting part reference plane contacts with the installation plane 51. Since relation of the assembling position of the moving part in the direction being parallel to the optical axis of the objective lens and the assembling position of the supporting part is decided by the installation plane 51, reduction of tilt accuracy of the moving part and the supporting part can be suppressed.;COPYRIGHT: (C)2009,JPO&INPIT
