摘要： A control unit inputs a control signal depending on whether reading at a high resolution is selected or reading at a low resolution is selected in an image reading unit. A first delay circuit and a second delay circuit output image data that is captured by a first CCD line sensor and a second CCD line sensor to an adder after retaining the image data for a time in accordance with the input control signal. The adder generates color image data by adding the image data that is captured by the first CCD line sensor to the image data that is captured by the second CCD line sensor.

摘要： Reference images on the respective surfaces of a reference document transported on a transportation path are read out by a first image reading section and a second image reading section, respectively. As a result a first reference readout image and a second reference readout image are acquired. in accordance with the difference between the changes in the sub-scanning direction in the first reference readout image and the changes in the sub-scanning direction in the second reference readout image, the reading cycle of the first image reading section X1 and the reading cycle of the second image reading section X2 are set. This makes it possible to equalize the magnifications of the respective images on the front and back sides of the document, even if the speeds of the document at the times of passing through readout positions for the front and back sides change over time, on account of the wear of a transportation roller.

摘要： A set pattern image with no displacement is recorded onto recording paper. In this set pattern image, the centers of auxiliary patterns are displaced in an auxiliary scan direction off a referential straight line passing through the centers of primary patterns. The image forming apparatus causes the set pattern image to be read, measures the displacements of the auxiliary patterns in the auxiliary scan direction off the referential straight line, and compensates for the displacements, such as by adjusting writing timings in the auxiliary scan direction so that the displacements become zero.

摘要： The image forming apparatus includes: an image data input section for reading a document as image data; a target value memory section for storing a target value of an input/output characteristic value when a reference document is read; a comparator for comparing the image data of the reference document and the target value so as to create a new input/output characteristic value; a fixed value memory section for storing a difference in input/output characteristic values as a fixed value between an original document and a copy document; and an adder for adding the fixed value to the image data of the reference document so as to output a resultant value to the comparator. By the provision of the fixed value memory section and the adder, the image forming apparatus can set a plurality of input/output characteristic values by reading the reference document once, thus reducing time for the procedure of setting the respective input/output characteristic values.

摘要： In order to prevent a situation that due to inherent variations in capability of a motor for a fan for blowing and sucking air, a motor for driving the suction transportation belt and the like, an external atmospheric pressure, and attaching of duct, the blowing force and the suction force upon the sheets become unstable, so that during suction attraction to the suction transportation belt, the sheets are not sucked parallel to the transportation direction but are sucked displaced, and therefore, a paper feeding error (jamming) results. An air blast nozzle for floating up the topmost sheet is disposed on the side to a sheet feeding cassette, and a suction transportation belt for suction attracting the topmost sheet is disposed above the sheet feeding cassette. A sheet pressing member is disposed above the sheet feeding cassette and a sheet rear end restricting plate. When the sheets have a small size which is smaller than a predetermined size, the sheet pressing member presses the topmost sheet at a rear end of the sheet from above and confines the sheet within a restricted area which is defined by the sheet rear end restricting plate and a sheet width restricting guide until the floated sheet is suction attracted to the suction transportation belt.
