摘要： An optical unit may include an image pick-up device, a lens unit and a holding member. The image pick-up device may convert a reflected light reflected from an original document to an electric signal, after the light is irradiated on the original document from a light source. The lens unit may image the reflected light on the image pick-up device. The holding member may hold the image pick-up device and lenses. The direction of a fluctuation of a focal length of the lens unit caused by heat and a direction of the fluctuation of a distance between the image pick-up device and the lens unit caused by heat may agree with each other.

摘要： 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).

摘要： 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.

摘要： An original reading unit is provided that is superior in the performance of the adjustment of line sensors. 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.

摘要： 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.

摘要： In a lens focusing and holding arrangement for an imaging system (60) including a photosensor array (510), the lens (570) is in contact with a reference surface or surfaces (274, 276) formed within the imaging system housing (200) and is translatable along the surface (274, 276) in directions toward and away from the photosensor array (510) in order to adjust the focus of the imaging system (60). A lens retention clip (600) is provided to secure the lens (570) within the imaging system housing (200) and to cause translational movement of the lens (570) along the imaging system reference surface (274, 276). When focusing the imaging system (60), the lens retention clip (600) is in a first operating condition in which the lens retention clip (600) applies a relatively small force tending to hold the lens (570) in contact with the housing reference surface (274, 276). After the desired focus has been set, the lens retention clip (600) is placed in a second operating condition in which the lens retention clip (600) applies a relatively high force tending to hold the lens (570) in contact with the housing reference surface (274, 276), thus locking the lens (570) in place.
