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: A mount for an optical device, such as a linear CCD array, is disclosed. The array is mounted on a base which is supported on a frame for adjustment relative thereto. The base is slidably movable on the frame for adjustment of the array in in-track and cross-track directions. The base is movable toward and away from the frame to provide a focus adjustment of the array. In order to provide a mount which can be easily and precisely adjusted to position the array along five degrees of freedom, adjustment screws are positioned such that the position of the array can be changed along one degree of freedom without changing the position of the array along any of the other degrees of freedom.

Abstract: An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

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.
