摘要： An optical scan apparatus includes an optical deflection unit (4), an image formation optical system (3), and curved surface mirrors (7a to 7d). Light fluxes from the image formation optical system (3) come onto the deflection surface (4a) of die optical deflection unit (4) in an oblique direction. Light fluxes from the optical deflection unit (4) come onto the curved surface mirrors (7a to 7d) in an oblique direction. When a boundary is a plane (6) including a normal at the center of the deflection surface (4a) and parallel to the main scan direction, the curved surface mirrors (7a to 7d) are arranged in the same space divided by the boundary and the scan speeds of fluxes scanning the surfaces to be scanned (8a to 8d) are almost identical. Thus, it is possible to obtain identical drive frequencies of the light sources (1a to 1d), thereby simplifying the circuit.

摘要： An image reading device comprising a rotary polygon mirror (6) for scanning a light flux from a light source (1), an imaging optical system (4) for forming on a reflection plane of the mirror (6) a linear image larger than the width in a main scanning direction of the one reflection plane, and a curved-face mirror (7), wherein the light source (1), the imaging optical system (4), the rotary polygon mirror (6) and the curved-face mirror (7) are disposed in different positions in a sub-scanning direction, a light flux from the imaging optical system (4) shines obliquely onto the polygon mirror (6), and a light flux reflected off the mirror (6) beams obliquely onto the curved-face mirror (7). Since one curved-face mirror can beam a light flux reflected from the rotary polygon mirror onto a surface to be scanned and the rotary polygon mirror having a small inscribed radius and many reflection planes can be used, satisfactory optical performance and high-speed feature can be realized.
