Abstract: The invention provides an image reading apparatus that scans an image from an original document including: a light source that irradiates a light to the original document; a photoelectric conversion element; a driving mechanism that relatively moves either one of the photoelectric conversion element or the original document in a predetermined direction with respect to the other; a detection sensor that detects a vector amount of movement of either one of the photoelectric conversion element or the original document in the predetermined direction with respect to the other so as to output a detection signal for each vector amount of movement that corresponds to a minimum unit of a reading area of the image; and a control unit that executes one cycle of operations each time when the detection signal is outputted from the detection sensor.

Abstract: An original scanning apparatus is described that scans an original placed on an original placing plane line by line by moving a scanning unit including a plurality of light-receiving elements that are arranged in a prescribed direction in a direction perpendicular to the prescribed direction. The original scanning apparatus includes: a pattern unit that is provided in a vicinity of a side of the rectangular original placing plane extending along a moving direction of the scanning unit; a control unit configured to calculate drive information in the moving direction per line-scanning cycle of the scanning unit based on a result of scanning the pattern unit; and a driving circuit configured to feed back the calculated drive information so as to control the scanning unit to thereby drive the scanning unit in the moving direction.
