PURPOSE:To prevent a vibration generated from a driving system in the course of copying, so that satisfactory copying accuracy can be obtained, by dividing a driving system supporting part for supporting the driving system, and an optical system supporting part for supporting an optical system in order to form a latent image, and interposing a vibration-proof material between both these supporting parts. CONSTITUTION:In a bracket 13, a projecting part 13a is formed, and on the other hand, on a horizontal plate 15, a roughly chevron-shaped fitting bracket 15a is provided, and between an inclined face 13b of this projecting part 13a and an inclined face 15b of the fitting bracket 15a, a vibration-proof material 14 is interposed. Accordingly, the vibration in the vertical direction and the horizontal direction can be effectively absorbed. As for this vibration-proof material 14, for instance, butyl rubber, a high viscous fluid, etc., can be used. In this state, both side plates 11, 12 being a driving system supporting part, and a horizontal plate 4 being an optical system supporting part are connected through the vibration-proof material 14. In such a way, it does not occur that an optical system of an image forming lens 16, etc., is vibrated due to a vibration of a driving system, and copying is executed with satisfactory copying accuracy.
