IPC: B41J2/44
Filed: 1984-08-09
Abstract: PURPOSE:To reduce nonlinear error of scanning lines through simple constitution by allowing plural light beams emitted by respective light sources to form spots on the reflecting surface of a pyramidal mirror, reflecting them in the same direction, and putting their optical axes close to one another. CONSTITUTION:Plural light beams B1-B4 emitted by mutually independent light sources 11-14 are reflected in the same directon by using a reflecting mirror having concave reflecting mirrors like a pyramidal mirror 9 to put optical axes of the respective light beams close to intervals of beam spots projected on a photosensitive drum 8, thereby allowing the light beams to strike a polygon mirror 6. Further, the light beams B1-B4 form spots on the reflecting surface of the pyramidal mirror 9 to obtain plural spot light sources which are close at the position of the pyramidal mirror 9, and the plural light beams are image-formed on the photosensitive drum 8 through one image forming lens 10. Thus, nonlinear errors of scanning lines are reduced through the simple constitution.
