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: In an electronic image printing apparatus of the type in which a light sensitive image recording layer (53) is exposed by a light beam (60,60',60''), an apparatus (57,92,154) is provided for determining and controlling the position of the light beam (60,60',60'') which comprises one or two alternating pluralities of diffraction grating patterns (4,6,8;18,20,22) disposed in a corresponding relationship with at least a portion of the light sensitive image recording layer (53) to produce a diffraction grid (52) which when irradiated by the light beam (60,60',60'') provides a diffracted beam which is representative of the position of the light beam on the diffraction grid (52). The position of the diffracted beam is detected to provide the requisite signal for controlling the position of the light beam (60,60',60'').

Abstract: In an image reading apparatus, a retreat control device moves a conveyance target through a conveyance mechanism, when a stop operation is performed by a stop control device, in an opposite direction to an image reading direction to a position further from a restart reference position set by a position setting unit. A reading control device again moves the conveyance target, which has been moved by the retreat control device, at a constant speed in the image reading direction under a predetermined condition; inputs a line start signal to a reading unit when an offset time set by a time setting unit has elapsed from a time point when the conveyance target reaches the restart reference position; and periodically inputs a line start signal to thereby cause the reading unit to perform a reading operation from a point; where the reading unit is located when the offset time has elapsed.

Abstract: A longitudinally displacable roll apparatus supporting a web (16) of record material is designed to maintain the roll (18) in proper alignment with associated processing equipment as the web is paid from, or wound onto, the roll. The apparatus comprises a pair of frame members supporting the roll. The roll is rotated by a drive shaft (195) having an interengageable coupler on the drive shaft and one end of the roll, to permit the roll to be rotatably driven by the roll drive shaft while not being directly secured thereto. The other end of the roll is engaged by means for displacing it longitudinally in accordance with signals derived from the actual path of the web so as to keep the web accurately on its intended path. The longitudinal and rotational drive system are able to operate independently of each other.

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: An image-reading device includes a platen glass for supporting a document, an end glass adjacent to the platen glass, a sheet member that connects bottom surfaces of the platen glass and the end glass, a feeder for feeding a document to the image-reading device, a carriage that includes a sliding member, a rod lens array mounted on the carriage, and a photoelectric transfer device for reading an image of the original document formed by the rod lens array. The carriage is biased against the platen glass and the end glass through the sliding member and moves relative to them. A controller drives the carriage at different speeds, one less than half the other, so that the carriage is moving slowly when the sliding member contacts the sheet member, thereby avoiding problems of wear of the sliding member and loss of synchronism of the motor that drives the carriage.
