PROBLEM TO BE SOLVED: To constitute fixing means for an optical system in one body and hold it in a housing in which a scanner device is stored by forming a fixing means which presses a 1st lens and a fixing means which presses a mirror in one body. SOLUTION: The fixing means 20 for the 1st lens 13 presses both the ends of the 1st lens 13 with bent tip parts by bending a sheet metal member with spring elasticity in, for example, a recessed shape and bending the lower ends of both end plane parts into the recessed shape by obtuse angles close to 90 deg.. Further, the center upper part of the recessed sheet metal is bent at three places in, for example, a channel shape to form pressing means for the mirror 14 on both the sides and a fall stopping means for the mirror 14 at the center part, so that the optical system components can be fixed. Further, the recessed shape sheet metal center part is bent to the outside of the recessed shape to provide a housing holding means, so that the 1st lens 13, mirror 14, and fixing device 20 themselves can be held in the housing 10. |
