摘要： In an optical scanning apparatus, an aperture is provided between a semiconductor laser in a light source unit and an oscillating mirror, and between a cylindrical lens and the oscillating mirror. When a light beam from the semiconductor laser comes into an reflection surface of the oscillating mirror, the optical scanning apparatus is configured to limit a beam width of the light beam to a width appropriate to the reflection surface, and then to ensure an irradiation position of the light beam in a main-scanning direction to come into the reflection surface of the oscillating mirror, by causing the light beam to pass through an opening of the aperture.

摘要： An image reading apparatus includes a reference pattern having slanting lines, which is provided outside a reading range and read by image sensors arranged at separate positions in a sub-scanning direction. A reference-position determining unit detects one of the slanting lines in the reference pattern based on image data output from one of the image sensors so that a position of the image data when one of the slanting lines is detected is determined as a reference position. First and second delay units have line memories which store image data read out from an original image having lines, the delay units delaying outputting of the image data from the line memories line by line. First and second determining units determine image data having color values at imaginary points. An error measurement unit selects one of the imaginary points whose image data has a minimum difference between the color values of the image data. First and second line correcting units output image data having the color values at a corrected position of each picture element by using an interpolation function, the interpolation function having a set of correction factors determined based on a distance between the selected imaginary point and the reference position.
