    Abstract: An optical adjustment arrangement for a scanning system comprises a main part having defined thereon a triangle with a center point and first and second base points. An optical part is positioned onto the main part so that the center point is aligned with the optical axis of the optical part. The right and left sides of the optical part are adjusted separately and independently by first and second adjustment devices. The position of the adjustment devices coincides with the base points of the triangle. When one of the first and second adjustment devices is moved in a direction perpendicular to the plane defining the triangle, the main part with the optical part is rotated around the line connecting the other of the first and second base points with the center point. Stabilizing parts acting as flexible hinges are preferably provided around the main part.

    Abstract: A copier comprises an original table for placing thereon an original sheet, a sub-scanning unit including an image reading sensor for reading an image on the original sheet and for scanning the original sheet on the original table, a printing unit which prints the image read by the image reading sensor on a printing sheet, and a control unit which controls the operation of the sub-scanning unit by selectively using a position profile control and a speed profile control. The operation start position and operation starting timing control of the sub-scanning unit using the position profile control permits high-speed continuous repetitive copying and high-accuracy enlargement, reduction, and transfer copying.

    Abstract: A document scan apparatus in which the position of a document support table relative to an optical system is detected during the relative movement between the document support platen and the optical system. A reference position marker is mounted on the document support table which directly reflects a light from a document illumination light source into an optical sensor array or a CCD sensor array through a mirror and a lens for causing the CCD sensor array to operate in a saturated range to generate a higher output signal level than an expected highest signal level of the CCD sensor array in the document scan operation; and by setting a threshold level of a comparator circuit to a high level which is exceeded by the higher output signal level of the CCD sensor array. The reference position marker is positioned within the field of view of the CCD sensor array for sensing the image of the document, so that the CCD sensor array sensing the document image also senses the reference position marker.

    Abstract: A flatbed scanner includes a transparent window and an optical ruler close to the transparent window along a scanning direction. The optical ruler has at least one oblique line arranged thereon. The flatbed scanner includes a scanner head having a scanning width larger than the width of the transparent window for capturing an image of the optical ruler while the scanner head is being progressively moved by a step motor. The flatbed scanner further includes a processing unit for calculating a jag width of a captured oblique line in the captured image and a controlling unit for controlling the step motor to adjust the speed of movement of the scanner head according to the jag width of the captured oblique line.

    Abstract: An image reader includes an original transport device to transport an original, and an image reading device including multiple image sensor arrays having image reading areas staggered relative to the transport direction of the original in such a manner that the multiple image sensor arrays are offset at least partially, in the main scanning direction of the original with a predetermined gap therebetween in the transport direction. There is at least one original transport speed detector to detect the transport speed of the original transported by the original transport device, a storing device to store a reference delay time period which is between when the image sensor arrays on the upstream side read a predetermined position relative to the transport direction and when the image sensor arrays on the downstream side read the predetermined position. Further, there is a misalignment amount calculator, and an image synthesizer to synthesize an image read by the image sensor arrays.
