Optical scanning system |
摘要 |
An optical scanning system has an image reading scanning system for emitting a first scanning beam of light to read an image of an object, an image forming scanning system for emitting a second scanning beam of light to form an image on a light receiving surface, and a light receiving element. Each of the first and second scanning beams is incident on the light receiving element when each of the first and second scanning beams is located at an end portion of a scanning area, and the first scanning beam and the second scanning beam have different optical characteristics. The optical scanning system also has a circuit for generating a horizontal synchronous signal for the image reading optical system and the image forming optical system, respectively, in accordance with light received by the light receiving element.
