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: The invention provides an image reading apparatus structured such that two or more line image sensors are arranged in a main scanning direction, in which it is possible to securely restrict a position shift of an image reading area caused by a line image sensor, thereby performing an image reading operation at a high quality. In the image reading apparatus in which the line image sensors are arranged, a marker is formed as an image in an overlapping portion of the line image sensors, the marker is read by the line image sensors themselves so as to inspect a relative position between the line image sensors and the marker with reference to a magnitude of an output thereof corresponding to a judging standard, and the positions of the line image sensors are shifted on the basis of the result, thereby preventing a position shift in a sub scanning direction from being generated.

Abstract: An apparatus for assembling components of a color optical scanner subassembly which includes a first filter member, a second filter member and a photosensor unit. The apparatus includes an imaging means for impinging an imaging light beam from a line object onto the first and second filter assemblies for producing spatially separated color component images of the line object on the photosensor unit. The apparatus also includes a physical adjustment assembly for holding and selectively adjusting the relative position of the first filter member, the second filter member and the photosensor unit 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 has first and second arrays of sensor assemblies extending in a main scanning direction for performing readings of an original document. Each of the sensor assemblies includes a sensor holder that undergoes pivotal movement about a single rotation center as a fulcrum along a wall of a unit base to bring the sensor holder to a predetermined position whereat the sensor holder can be fixed to the units base wall. A line sensor is mounted relative to the sensor holder so as not to be shifted in the main scanning direction or in a sub-scanning direction, and to undergo movement in an approaching or a separating direction so as to be brought into contact with or separated from, respectively, the unit base wall and an original support plate attached to the unit base. A focus setup unit moves the line sensor in the approaching or separating direction and positions the line sensor at a location whereat focus can be adjusted.
