Abstract: Array adjusting apparatus for a raster scanner with scanning arrays (40, 41) supported by displaceable blocks (106, 108). The blocks are supported against a spring bias 132 on members 116, 117, screws 120 permitting the members 116, 117 to be moved to raise and lower arrays 40, 41 and thereby adjust the height of the arrays within the optical system (55-59). A side member (140) permits, through screw 120 min , adjustment of the array position in the optical path along the horizontal. Screw members (152, 154) enable adjustment of the array focus, with pivot means (174) permitting pivoting of the array to bring the array into perpendicular relationship with the optical path.

Abstract: 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 assembly includes a sensor base and plural image sensors. Each image sensor includes plural sensor pixels. The plural sensor pixels and the plural image sensors are arranged in the same direction. Each image sensor is fixed on the sensor base, and each image sensor corresponds to a next one so that all image sensors can be aligned. There is a predetermined gap between two adjacent image sensors. Therefore, each image sensor is not skew and shifted when the image sensor assembly is mounted on the carriage, and the skew problem between each image sensor and the carriage base can be solved by micro-adjusting the position of the sensor base relative to the carriage base.

Abstract: An image sensor sub-assembly for a scanner or other image acquisition device includes an image sensor array that detects light imaged by a scanner optical system and an image sensor module that enables calibration of the position of the image sensor array relative to the optical system. In this way, with the optical system being constructed within tolerances, the module enables alignment of the image sensor array to the optical system by its adjustment. Preferably, the sensor module 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 enables positioning of the sensor array with six degrees of freedom. Further, the electronic circuit board, on which the sensor array 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.

Abstract: In an image reading apparatus having an easy-toad-just 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: There is disclosed an image reading apparatus in which the scanning optical system having a slit is caused to scan in a short-side direction of the slit, and light passed through the slit and reflected from or transmitted through an original is guided to a solid-state image pickup element through an optical image forming element so that the image is formed on the solid-state image pickup element and is read. In the apparatus, opening portions for detecting a shift in relative positional relationship between the slit and the solid-state image pickup element are formed in both end portions of the slit in its longitudinal direction corresponding to a portion other than an effective image region of the solid-state image pickup element.

Abstract: An image reading apparatus for reading an image of an original and converting it into an electrical signal, and particularly for reading the image by primary-scanning and secondary-scanning the image by a one-dimensional image sensor. This apparatus has one or two one-dimensional image sensors and is constructed such that the image reading state (for reading by the image sensors) differs when the image is placed in a vertically facing posture at an illuminating position compared to when the image is placed in a horizontally facing posture at the illuminating position, and can properly read the image and reproduce the same when the image is placed in any of these postures.
