Abstract
A structure 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 using an elastic force of a spring connected to an upper cover of a light scanning device and an inside wall at the opening of the shutter increases the size of the structure of the shutter and the structure of the light scanning device due to the position of the spring. Therefore, 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 portion 218e provided at the recess 218b. The recess 218b is provided at a side opposite to the light source units with a polygon mirror 203 being interposed therebetween.
