PURPOSE:To assemble an electronic copying machine without any adjustment and to secure driving stability by composing a slider of a rigid frame and supporting the slider at three points. CONSTITUTION:Sliders 70 and 75 of the 1st and the 2nd optical systems of a scanning optical driving mechanism are composed of rigid frames, and support members 45a-45c, and 55a-55c provided on both reverse surfaces of sliders 70 and 75 face each other on sliding members 14a and 14b with smooth surfaces which are supported by the frames 12a and 12b on both sides, and stuck onto rail parts 13a and 13b formed by bending upper parts of the frames 12a and 12b inwardly. Namely, the sliders 70 and 75 are supported at three-point by support members 45a and 45b, and 55a and 55b placed on one rail part 13a, and support members 45c and 55c placed on the other rail part 13b, and mounted slidably on the rail parts 13a and 13b with members 14a and 14b between. The members 14a and 14b are made of stainless steel materials and the members 45a-45c, and 55a-55c are made of ''Teflon'' resin with a small coefficient of friction. |
