Abstract: In an imaging system (60) of the type having a photosensor package (510) and at least one optical component (570), e.g., a lens, mounted within an optical assembly housing (200), the photosensor package (510) is mounted to a substrate (540), such as a printed circuit board, which has a shorter length than the photosensor package (510). This shorter length causes the ends of the photosensor package (510) to extend beyond the substrate (540) and, thus, be exposed. The exposed ends (524, 526) of the photosensor package (510), in turn, allow the photosensor package (510) to be directly referenced to reference surfaces (442, 446, 450, 452) formed on the optical assembly housing (200).

Abstract: An integrated image module for a document scanner includes a one piece die cast housing having a datum element and a support element. An imaging sensor array is enclosed in the housing. An array bias element urges the imaging sensor array against the datum element to provide accurate placement of the sensor array relative to the housing. A transport mechanism is attached to the housing so that the position of the transport mechanism accurately corresponds to the position of the imaging sensor array. The lens and the lamp for illumination are also attached to the housing so that the primary components of the imaging portion of the scanner are contained in a single module.

Abstract: An optical scanning unit includes a light source, a lens, a deflector, a lens holder, a support member, a force-generating member, and a force-transmitting member. The light source emits a light beam. The lens passes through the light beam. The deflector rotatably deflects the light beam coming from the lens. The lens holder, provided between the light source and the deflector, holds the lens. The support member has a first face faced to a vertically-downward direction, and extends in a direction from the light source to the deflector. The lens holder is movably supported by the first face of the support member. The force-generating member, provided to a second face of the support member, generates a force. The second face is opposite to the first face. The force-transmitting member transmits the force generated by the force-generating member to the lens holder to move the lens holder along the first face.

The first portion has a plurality of elongated holes therein each for receiving a fastener to mount the mounting bracket to a scan head frame. The second portion includes a cutout section therein for allowing an image sensor of the image sensing unit to receive an image from an optical unit of the scanner. A pivot hole in the first portion is centered about a width of the cutout section. When the mounting bracket is mounted on the scan head frame, the elongated holes in the first portion permit linear adjustment of the mounting bracket relative to the scan head frame and the pivot hole permits angular adjustment of the mounting bracket relative to the scan head frame.

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.
