Abstract:
A rotational reciprocation motion apparatus, and a scanner for image display are provided to secure driving condition within an effective rotational angle and increase a restoring force by deforming a rotator shape and arranging a rotational angle. A rotator(412) rotates at both directions within a rotational angle according to a driving signal, and a stator(400) stops the rotation of the rotator by contacting with the rotator at a rotation termination point. The rotational angle is the angle between the rotation start point and the rotation termination point. The stator consists of an elastic body, and an elastic material is attached to an outer wall of the stator. The stator may be a leaf spring or a coil spring, and a rotator includes a receiving unit which receives the stator at its inside. A first inner wall of the receiving unit meets with the first outer wall of the stator at the rotation start point.
Abstract:
A scanning module and an image reading device equipped with the same are provided to realize the scanning module integrated with an image sensor by using the small number of parts and adjust an arrangement state of the image sensor anytime. A frame(501) arranges a light source, a mirror, and a light collecting lens while forming an optical path to scan a document. A base plate(570) is attached with the image sensor(316) receiving the light collected by the light collecting lens. An arrangement member(550) is placed between the light collecting lens and the base plate. An arranger arranges a position and a tilt angle of the image sensor over 5 degrees of freedom by adjusting the position fixing the arrangement member to the frame and the position fixing the base plate to the arrangement member with the first and second adjuster.
Abstract:
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.

A first connection member (25) is provided to the part of one of the reading sensors facing the part of the adjacent one of the reading sensors. The first connection member (25) protrudes toward the adjacent one of the reading sensors. A second connection member (27) is provided to the part of the adjacent one of the reading sensors facing the part of the one of the reading sensors. The second connection member (27) protrudes toward the one of the reading sensors. The first and second connection members are brought into contact with each other by being urged by a spring (29).

Abstract:
An integrating cylinder for use as an illuminator for a film scanner includes a hollow cylinder including an inner surface defining a cavity therein and an outer surface, a diffusing layer of reflective material covering an inner surface of the hollow cylinder, a first end plate for sealing a near end of the hollow cylinder, and a second end plate for sealing a far end of the hollow cylinder opposite the near end. The hollow cylinder defines a slit formed parallel to a longitudinal axis of the hollow cylinder between the inner and outer surfaces at a predetermined line along a circumference of the hollow cylinder. The first end plate defines a hole which is decentered from the longitudinal axis of the hollow cylinder and can be tilted at a predetermined angle to the longitudinal axis of the hollow cylinder towards an area of the inner surface of the hollow cylinder. Additionally, the hole is located at a predetermined angular separation around the circumference of the hollow cylinder from the slit for receiving a light beam directed at the predetermined angle to the longitudinal axis into the cavity. After reflections in the cavity, the light emerges from the slit to form a line of uniform diffuse light.

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).
