<p>PROBLEM TO BE SOLVED: To provide an optical scanner that is able to support an optical element accurately.SOLUTION: An optical scanner 1 according to the invention comprises in a lower frame 110: a support wall 115; a first wall (first holding wall 140) abutting on an fθlens 6; a second wall (first left external wall 111A) extending from the first wall; and a third wall (reinforcement wall 150) extending from a position on the first wall, which position is different from that of the second wall. The optical scanner 1 comprises a plate spring 130 one end of which abuts on the fθlens and the other end of which is supported by a scanner frame 100, and which presses the fθlens 6 toward the first wall. The second wall extends in a direction intersecting the first wall. The third wall extends opposite the fθlens 6 in the direction in which the fθlens 6 and the first wall face each other. The first wall abuts on the fθlens 6 at least between the connected position of the second wall and the connected position of the third wall.</p> |
