    摘要: A distance-measuring optical apparatus for measuring a distance to an object as a target comprises an imaging optical system; an image sensor; a driving section for moving at least the imaging optical system substantially perpendicular to an optical axis; an image sensor control section for outputting a periodical timing signal for designating a timing at which the image sensor takes an object image; and a driving control section for controlling the driving section to reciprocate the imaging optical system. The timing signal is periodically output when the imaging optical system is located near two positions away from each other in a direction substantially perpendicular to the optical axis. The distance-measuring optical apparatus further comprises an image processing operation section for finding, through an operation, a distance from the imaging optical system to the object using the image signal when the imaging optical system is at each of the two positions.

    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.
