ABSTRACT:
An optical scanning apparatus for scanning a manuscript, and for optically reading information recorded on the manuscript, having: a plurality of semiconductor lasers for emitting laser lights, whose wavelengths are different from each other; a plurality of collimator lenses each corresponding to respective one of the semiconductor lasers, and for converting the laser lights emitted from the corresponding semiconductor lasers into parallel laser lights respectively; a polygon mirror for deflecting each of the parallel laser lights in a main scanning direction in order to scan the manuscript; and an image forming lens for converging each of the deflected laser lights on the manuscript, wherein collimator setting distances between the collimator lenses and the corresponding semiconductor lasers are different from each other in accordance with differences between the wavelengths of the laser lights.
