Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a galvano drive device capable of detecting wear of motor bearing at an early stage.

SOLUTION: A drive control means 5 includes: wear detection means 15 that has a determination mode for outputting a determination drive signal dpc to detect wear degree of bearing of an output shaft 3 of a drive motor 2 on the basis of the rotating state of a galvanometer mirror on the basis of the determination drive signal; and switching means 11, 14 each of which disables the operation of feedback control units 7 and 8 during determination mode and supplies a rotation state signal rt only to the wear detection means 15.
