    Abstract: In an image reading apparatus having an easy-to-adjust optical system, a unit is composed of a first sub-unit including an image forming lens and a second sub-unit including a solid-state image pickup element. The first sub-unit and the second sub-unit are mutually adjusted in position in X-axis, Y-axis and Z-axis while the two sub-units are also adjustable around X-axis and Z-axis. After the first sub-unit and the second sub-unit are adjusted using a tool, the unit is then assembled into the apparatus. The unit is rotated around an optical axis of the image forming lens for adjustment of perpendicularity. The unit is also rotated around a line direction of the solid-state image pickup element for adjustment of scanning synchronization (the reading position in a sub-scan direction).

    Abstract: An apparatus (100) for assembling components of a color optical scanner subassembly which includes a first filter member (80), a second filter member (70) and a photosensor unit (52). The apparatus includes an imaging means (50, etc.) for impinging an imaging light beam from a line object onto the first and second filter assemblies (80, 70) for producing spatially separated color component images (53, 55, 57) of the line object on the photosensor unit (52). The apparatus (100) also includes a physical adjustment assembly (114, 116, 120, 122, 126, 128, 132, 134, 150, 156, etc.) for holding and selectively adjusting the relative position of the first filter member (80), the second filter member (70) and the photosensor unit (52) in response to data signals generated by the photosensor unit. This positioning accurately locates the filter members relative to the photosensor unit for optimizing performance of the color optical scanner.

    Abstract: An original reading unit is provided that is superior in the performance of the adjustment of line sensors.
    According to the present invention, between a unit base and a transparent original support plate, multiple sensor assemblies are arranged, to form a zigzag pattern, as a first array for reading an original and a second array for reading the original following the first array. Each of the sensor assemblies includes a sensor holder, a line sensor and a focus setup unit. Each of the sensor holders, which serve as fulcrums, are rotatable at a single pivot (a rotation center), along the wall of a unit base that is parallel to the original support plate. When the sensor holders are rotated and positioned at predetermined locations, they are fixed to the wall. The line sensors 51 are held, relative to the sensor holders, in the main scanning direction and in the sub-scanning direction, and are moved in an approaching or separating direction in which the line sensors approach or are separated from the wall and the original support plate. The focus setup units, each of which includes coil springs and spacers, move the line sensors 51 in the approaching or separating direction, and position the line sensors 51 at locations whereat focuses are adjusted.

    Abstract: An image sensor sub-assembly for a scanner or other image acquisition device includes an image sensor array (134) that detects light imaged by a scanner optical system and an image sensor module (130) that enables calibration of the position of the image sensor array (134) relative to the optical system. In this way, with the optical system being constructed within tolerances, the module (130) enables alignment of the image sensor array (134) to the optical system by its adjustment. Preferably, the sensor module (130) is calibrated to defined standards, making the optical system's calibration independent of the specific module and the module's calibration independent of the specific optical system used in a given scanner. Preferably, the module (130) enables positioning of the sensor array (134) with six degrees of freedom. Further, the electronic circuit board, on which the sensor array (134) is integrated, is separate from the board, on which the analog to digital converters are located. This has the advantage of enabling replacement of the analog to digital converters, a primary source of improper operation in the scanner's electronic components, without requiring the replacement of the optical sensor array, and thus re-alignment.
