    Abstract: An image scanning unit for correcting a variation in magnification caused by an inclination of optical visual-line between a manuscript and a photoelectric conversion element when a full-speed scan reciprocating bed and a half-speed scan reciprocating bed are scanned in the sub-scan direction. The image scanning unit has: an optical system that leads light reflected on the manuscript to the photoelectric conversion element; a marking that is disposed on the optical visual-line of the full-speed scan reciprocating bed; a light source that supplies light to the marking; and a control circuit for accumulating marking information that is input through the optical system to the photoelectric conversion element and detecting an inclination of optical visual-line by comparing the accumulated marking information and regular marking information at regular optical visual-line, and for canceling the variation in magnification in the sub-scan direction caused by the detected inclination of optical visual-line.

    Abstract: In an image forming apparatus in which an exposure is conducted by scanning of a laser beam, the apparatus includes a photoreceptor for forming a latent image thereon; an exposure device having a rotary polygonal mirror for exposing the photoreceptor, wherein the laser beam is deflected and scanned onto the photoreceptor by rotating the rotary polygonal mirror; a controller for controlling a linear speed of the photoreceptor; and a braking device for decreasing forcibly a speed of rotation of the polygonal mirror. When the controller decreases the linear speed of the photoreceptor according to an image formation mode, the braking device decreases the speed of rotation of the polygonal mirror.

    Abstract: A mounting bracket for an image sensing unit of a scanner according to one example embodiment includes a first portion and a second portion extending from the first portion. The first portion has a plurality of elongated holes therein each for receiving a fastener to mount the mounting bracket to a scan head frame. The second portion includes a cutout section therein for allowing an image sensor of the image sensing unit to receive an image from an optical unit of the scanner. A pivot hole in the first portion is centered about a width of the cutout section. When the mounting bracket is mounted on the scan head frame, the elongated holes in the first portion permit linear adjustment of the mounting bracket relative to the scan head frame and the pivot hole permits angular adjustment of the mounting bracket relative to the scan head frame.

    Abstract: A method for adjusting a scanning module includes the steps of: providing a first fixing force to mount an adjustment assembly, to which an image sensor is attached, onto a base of the scanning module and loosely fixing the adjustment assembly to the base with a first fixing force; adjusting a relative position between the adjustment assembly and the base of the scanning module, and testing a first adjustment result until the first adjustment result is accepted; securing the adjustment assembly to the base of the scanning module with a second fixing force; and removing the first fixing force. The first and second fixing forces come from different sources.

    Abstract: An electronic device includes a carriage on which an image sensor is mounted, a motor that drives the carriage, and servo-control-containing printed matter provided in one or more detection areas of the image sensor or one or more independently provided optical sensors. The servo control information is used for speed control and initial position detection of the carriage. A servo controller performs the servo control on the motor via a motor driver based on the read servo control information. The printed matter is provided on a rear or underside surface of a support structure in areas irradiated by a light source for the image sensor. Printed matter for speed control may be provided in one area and printed matter for initial position detection in another. Servo control information on the printed matter may be read using a dummy pixel region of the image sensor.
