Abstract: The present invention improves the grade of an output image formed by composition of plural images in a simple and low-cost constitution. Cylindrical mirrors corresponding to the respective colors (K, Y, M, C) are respectively provided with a scanning line inclination and bend correcting mechanism. Further, the side registration, the lead registration and the scaling factor are corrected by controlling the modulation timing of a laser beam corresponding to each color. The color aberration caused by the change in the ambient environment is corrected by detecting a variation in the positional relationship between the respective beams by a main scanning position detecting sensor and a sub-scanning position detecting sensor provided by each color to be reflected in the control for the modulation timing.

Abstract: A light scanning device deflects a plurality of light beams by a deflecting means performs divided scanning on a single scanning line on a photoconductor with the plurality of deflected light beams. When the scanning line is scanned, a detecting means detects a light beam passing through a predetermined position in front of a position where the light beam first strikes an image forming range on the photoconductor. An oscillating means oscillates a specified number of clocks in a time interval from when the light beam is detected by the detecting means until it is detected thereby again. An adjusting means makes adjustments so as to irradiate a plurality of light beams based on clocks oscillated by the oscillating means. In a time interval after the light beam is detected by the detecting means until it is detected thereby again, a plurality of light beams are irradiated based on the specified number of clocks. Therefore, even if unevenness occurs in the deflecting speed of the deflecting means, dots can be formed at the same intervals in scanning a plurality of scanning lines. Thus, it is possible to prevent discontinuous joints occurring in each of the images formed with a plurality of light beams.

Abstract: A line sensor apparatus is adapted to read a character or pattern image on a document. In this apparatus, an illumination device for illuminating the document, a optical lens for focusing the light beam reflected by the document, a CCD line reading sensor for photoelectrically converting the light beam focused by the optical lens into an electric signal, and a holding member for holding the CCD line sensor and the optical lens are assembled as one body in such a manner as to constitute a carriage device. A uniformly radiated heat-radiating plate is in contact with the entire botttom surface of a support for the CCD line sensor, so that the heat generated by the CCD line sensor is radiated from the heat-radiating plate. Further, the CCD line sensor is kept in tight contact with the holding member, so that the heat generated by the CCD line sensor is also radiated from the holding member.
