PURPOSE:To hold an optical path correctly by fitting a subframe to which mirrors, a lens, etc., forming an optical system is fitted to the fitting part of a main machine body through an elastic body, and absorbing strain due the temperature variation and flatness of the main machine body. CONSTITUTION:The 1st and the 2nd mirrors 30 and 31, and lens 32 which form the optical system 25, and an image sensor 33 are fitted to the subframe 29. The subframe 29 is formed of a material having superior heat resistance and rigidity, projection parts 35 as fitting parts are formed at four right and left positions sideway, and those projection parts 35 are fitted to square holes 37 of both-side frames 36 and 36 of the main machine body 20 through an elastic body respectively. Consequently, the strain caused by unevenness of temperature variation of the main machine body 20 and a defect in the flatness of an installation place is absorbed to maintain the optical system on a set optical path correctly, obtaining the fitting device suitable for facsimile, etc. |
