Abstract: An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

Abstract: An image reader adopting an off-axial optical system, an adjustable imaging mirror and a CCD fixed to a highly rigid structure. Since the relative position between reflecting and imaging mirrors can be set highly accurately, adjusting only the CCD-mounting position allows a required specification of the read image to be met. The imaging mirror can easily be adjusted without distorting the reflecting surface. The reflecting and imaging mirrors, and the CCD-mounting-position adjuster are positioned directly to reflecting-mirror supporting sections, imaging-mirror supporting sections, and CCD supporting sections, which are integrated with a carriage casing, and fixed to them. The CCD is fixed to the carriage casing with the CCD-mounting-position adjuster. An imaging mirror close to a diaphragm and adjacent to the image is supported by a mirror adjusting plate, which can be displaced to adjust the position of the imaging mirror.

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).
