Abstract
An optical scanning apparatus includes a polygonal mirror configured to deflect a light beam emitted from a light source such that the laser beam scans a member to be scanned, a drive motor configured to rotate the polygonal mirror, aboard on which the polygonal mirror and the drive motor are mounted, an installation portion where the board is installed, a rubber member provided between the board and the installation portion, and an adjustment unit configured to position on the board with respect to the installation portion and to adjust inclination of the board with respect to the installation portion by deforming the rubber member.
Claims7
An optical scanning apparatus comprising:
- a polygonal mirror configured to deflect a light beam emitted from a light source such that the light beam scans a member to be scanned;
- a drive motor configured to rotate the polygonal mirror;
- a board on which the polygonal mirror and the drive motor are mounted;
- a first installation portion and a second installation portion where the board is installed and a fixing portion where the board is fixed rigidly, wherein the first installation portion and the second installation portion are arranged on sides opposite to each other across a first virtual plane connecting an optical axis of the lens and a rotation shaft of the polygonal mirror, and the first installation portion and the second installation portion are arranged on a side opposite to the fixing portion with respect to a second virtual plane intersecting the first virtual plane;
- a first rubber member provided between the board and the first installation portion, wherein the first rubber member makes contact with the board and the first installation portion;
- a second rubber member provided between the board and the second installation portion, wherein the second rubber member makes contact with the board and the second installation portion;
- and
- a first screw configured to position the board with respect to the first installation portion and to deform the first rubber member, wherein the first adjustment unit adjusts inclination of the board with respect to the first installation portion by deforming the first rubber member;
- and
- a second screw configured to position the board with respect to the second installation portion and to deform the second rubber member, wherein the second adjustment unit adjusts inclination of the board with respect to the second installation portion by deforming the second rubber member.
