Galvanomirror mounting apparatus

摘要

A supporting surface is formed on a portion of a base member of a galvanomirror in a direction parallel to the reflection surface of a mirror. A galvanomirror container section opened in a direction parallel to the reflection surface is formed in a carriage and a bearing seat surface is formed inside the galvanomirror container section. The center axes of the supporting surface and of the bearing seat surface are aligned to the direction parallel to the reflection surface. Only by inserting the galvanomirror into the galvanomirror container section from the direction parallel to the reflection surface, the supporting surface abuts on the bearing seat surface 29. As a result, a mounting apparatus for mounting the galvanomirror 20 into the carriage 2 while adjusting the inclination of the reflection surface can be made small and the structure thereof can be simplified.
