<p><P>PROBLEM TO BE SOLVED: To provide an optical scanner that can suppress vibration of a support wall. <P>SOLUTION: A casing 100 of an optical scanner 1 includes a support wall 110 that supports a polygon mirror 40, a columnar reflector supporting part 131A that extends from the support wall 110 to support a reflector 73A, a columnar reflector supporting part 131B that extends from the support wall 110 on the opposite side of the reflector supporting part 131A across the polygon mirror 40 when viewed from the facing direction where light source devices 20A, 20B and the polygon mirror 40 face each other, and a reinforcing wall 151 that extends from the support wall 110 between the light source devices 20A, 20B and the polygon mirror 40 to connect the reflector supporting parts 131A and 131B. The reinforcing wall 151 has openings 153 through which laser beams, emitted from the light source devices 20A, 20B to the polygon mirror 40, pass. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
