PROBLEM TO BE SOLVED: To provide an optical scanner in which an optical member is pressed and held at an appropriate pressure, and positional deviation of the optical member is hard to cause even in the application of shock.SOLUTION: An upper surface and a lower surface of an emission folding mirror 108 are sandwiched between a first pressurizing part 115 of a leaf spring 112 and an abutting rib 111e, and front and rear surfaces of the emission folding mirror 108 are sandwiched between a second pressurizing part 117 of the leaf spring 112 and each of abutting ribs 111d. Thus, the emission folding mirror 108 is retained. Also, only a fixed end part 112c of the leaf spring 112 is fixed to an upper surface 111a of a holding member 111, and a displacing end part 112f of the leaf spring 112 is kept displaceable without being fixed. Therefore, the entire leaf spring 112 is elastically deformed in accordance with displacement of the displacing end part 112f of the leaf spring 112, and the first and the second pressurizing parts 115 and 117 are also displaced. |
