In a configuration in which a shutter is moved in a first direction by a motor, an opening is provided in the shutter, and the shutter is moved in a second direction by employing the elastic force of a spring connected between an inner wall of the opening in the shutter and an upper cover of a light scanning device, the size of the shutter and the light scanning device is increased because of the position of the spring. So, a recess (218b) is provided in an opposing surface (218g) of a cover (218) opposing a shutter (300), and a spring (310) for sliding the shutter (300) is connected to a connection part (218e) provided to the recess (218b). The recess (218b) is provided on the opposite side from a light source unit across a polygon mirror (203). |
