PROBLEM TO BE SOLVED: To realize a low noise environment and to obtain a good quality image by disposing rubber vibration isolators near an area where a drive part and a structure are in contact with each other and between the structure and a support plate. SOLUTION: After a rubber vibration isolator 29 is attached to a plate 21a, a screw 33 is screwed into fasten a screw part 33c into the boss 32 of a frame 31, thereby fixing a collar so that the rubber vibration isolator 29 is compressed to a proper degree. Additionally, a rubber vibration isolator 34 is disposed also for a boss 35 situated in a position different from the position of the boss 32 of the plate 21a. The cross-section of the rubber vibration isolator 29 is approximately square, and it is positioned by being pressed and inserted so as to match its perimeter. By disposing the rubber vibration isolator 34 near a beating 27 and firmly retaining the positions of the drive part 20 and frame 31 in relation to each other in such a manner, the positional relations between the parts are not impaired, vibration of the frame is effectively restricted to achieve low noise, and degradation of image quality can therefore be prevented.
