Abstract: An improved raster scanner, and electrostatographic printing machines which use such scanners, in which facet tracking is achieved by incorporating a semiconductor laser having an electronically tunable wavelength and a wavelength dispersive element which directs the laser beam onto the facets of a rotating polygon. The wavelength dispersive element is positioned, and the wavelength output from the laser is adjusted, such that as the polygon rotates the laser beam produces a spot on a facet which tracks the facet.

Abstract: A method for automatically aligning a charge coupled device of a scanner by using a software contained in the scanner instead of physically aligning the charge coupled device is disclosed. The scanner comprises a charge coupled device (CCD) having an array of optic sensors for converting a reflected line image into an analog signal array, an analog-to-digital (A/D) converter for converting the analog signal array into an image data array, and a test region having a positioning mark in it. The method comprises the following steps of: (1) generating an image data array which comprises the image of the test region in it by using the CCD and the A/D converter; (2) identifying the positioning mark from the image data array; and (3) setting an effective scanning range which defines the start and stop positions of valid image data within the image data array according to the identified positioning mark.

Abstract: A scanner having an image sensor unit having a CCD linear array for electro-optically scanning an image of an original in a main scanning direction to convert the image into image data signals is used to scan, through a table sheet having a transparent document area and a pattern area which includes a stripe pattern inclined with respect to the main scanning direction, an original placed under the document area to read data of the original, and the scanner is moved relative to the original in a subscanning direction perpendicular to the main scanning direction. A pattern signal obtained by scanning the pattern area then is analyzed to detect an amount of relative movement of the scanner in the subscanning direction from the movement of the stripe pattern in the main scanning direction. Accordingly, the reading resolution in the subscanning direction which varies depending upon a high or low degree of the speed of relative movement of the scanner in the subscanning direction can be maintained suitably by adjustment of the speed of movement, or the reading speed can be raised for a predetermined resolution.

Abstract: As a beam is deflected to transversely scan sheets as they are conveyed past the deflected beam for transferring image intelligence between a document image form on the sheet and a video signal form for processing by a video processing circuit, the beam is deflected in the direction of the travel of the conveyed sheets at a velocity relative to the velocity of travel of the sheets to produce complementary motion so that the entire sheet is scanned by the beam during a single frame video signal. The operations of the video processing circuit, sheet transport mechanism and beam deflection signal generator are time synchronized with the vertical synchronizing signal associated with the video signal such that each sheet is positioned at the location at which the first upstream line of the raster of scanned lines is produced when the deflections of the beam and transduction of the video intelligence signal is commenced.

Abstract: PROBLEM TO BE SOLVED: To precisely correct a sub scanning direction positional shift of an image without incurring high costs.
SOLUTION: A light source unit can simultaneously scan two scanning lines (line 1 and line 2), and includes a semiconductor laser which includes nine light emitting units (A, B, C, D, E, F, G, H and I) including a light emitting unit C as the default light source used for scanning with line 1 and a light emitting unit G as the default light source used for scanning with line 2. In scanning, one or two light emitting units are selected from nine light emitting units for the scanning light source for every line according to the amount of the sub scanning direction positional shift, and driven and controlled. Thus, the sub scanning direction positional shift is precisely corrected without incurring high costs.

Abstract: It is intended to provide an image forming apparatus and image forming method capable of obtaining a comparatively high-quality image output even under a correction mode that gives preference to processing time required for correction, and capable of suppressing interruption of image formation to the utmost under operational condition such that internal temperature changes continuously. There are saved last five detections of positional shift quantity under first correction mode that gives preference to correction accuracy for each temperature band. Under second correction mode that gives preference to processing time required for correction, there is calculated a difference of a value actually obtained through measurement and an average value of data history belonging to a target temperature band (#7 through #9). Furthermore, the difference is multiplied by a reliability coefficient of main scanning direction and that of sub scanning direction, respectively, to determine correction quantity (#10, #11). Thereby, excessive change of correction quantity is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of properly correcting a main scanning scale factor without degrading a required printing quality. SOLUTION: In a main scanning scale factor correcting process, for each of one or more correction points (at l-th, m-th, and n-th pixels) on each of lines along which scanning is carried out on a photosensitive drum 11 by laser light, the final bit data of pixel-division-modulated pixel data of a pixel immediately preceding each correction point is added as the leading bit data of the pixel-division-modulated pixel data of a pixel located at the correction point. The same processing as above is sequentially performed on pixel data of pixels located subsequently to the correction point to sequentially shift the pixel-division-modulated pixel data of pixels to pixel data of the respective following pixels by bit, to thereby generate pixel data of a new pixel to be added on each of lines. The generated pixel data of the new pixel is outputted in synchronism with an image clock of a fixed frequency. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: An image reading device includes reading means, which reads an original into image data by scanning the original in the main scanning direction at an image reading width while the original is being fed in a sub scanning direction; and setting means, which sets the image reading width to a maximum reading width of the reading means when reading settings information including a user instruction for setting the image reading width to the maximum reading width is input.
