Abstract:
A image reading apparatus includes a plurality of point light sources, arranged in a straight line state, configured to output light for lighting a document situated on a contact glass from a lower side of the contact glass, a light leading member, positioned in front in a light outputting direction of the light output from the point light sources, configured to lead the light output from the point light sources so as to irradiate along a main scanning direction toward the document situated on the contact glass, and a photoelectric conversion element configured to receive reflection light from the document. The light leading member includes positioning means configured to make a gap between each of the point light sources arranged in a line state and the light leading member constant and make an arrangement direction of the point light sources be positioned along a longitudinal direction of the light leading member.
Abstract:
The present invention is directed to a hand-held scanning device (10) in which the scanning device housing window (150) is attached directly to the optical assembly (40). In this manner, alignment between the window (150) and the optical assembly (40) may be maintained even when the housing (20) is being subjected to stress. The window (150) is also designed to float with respect to at least a portion of the housing (20), thus allowing the housing (20) to flex without causing movement of the window (150) relative to the optical assembly (40). A tortuous path seal arrangement (360) may be provided between the window (150) and the housing (20). The tortuous path seal (360) allows the housing (20) to move relatively to the window (150), and yet inhibits the entry of dust and other contaminants into the interior(21) of the housing (20) through the space provided between the window (150) and the housing (20).
Abstract:
An improved lens focusing and referencing arrangement for an imaging system (60) of the type which may include a photosensor array (152). The imaging system housing (100) may include reference surfaces (324, 326, 354, 356) configured such that they contact the lens (210) only near the ends thereof in order to minimize the effect of any irregularities in the reference surfaces (324, 326, 354, 356).
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:
Film gate for a virtual contact scanner includes a base having a precision site adapted to receive a solid-state scanner assembly so as to position the sensor photosites at a precise spacing from the film image plane. A separate circuit board carrying control circuits for the scanner assembly is clamped over the scanner with contact terminals aligned with mating input/output terminals of the scanner assembly. Preferably the scanner terminals are aligned with open slots in the substrate and electrical contact is made between the scanner and circuit board terminals by means of compressible electrically conductive pads. Clamping force is concentrated over the region of electrical contact between the circuit board and scanner terminals to assure good electrical contact.
Abstract:
A mirror support device arranged in both ends of a stick-like mirror for holding the mirror including an inner side plate, comprising a mirror insertion opening formed in the inner side plate, the mirror insertion opening for inserting an end of a mirror; an outer side plate connected to the inner side plate, comprising: a mirror stopper plate for regulating positions of a right and a left end face of the mirror inserted into the mirror insertion opening; and a clip hole, the mirror stopper plate and the clip hole being formed in the outer side plate; and a clip for fixing the mirror, the clip being inserted into the clip hole from a same direction as inserting direction of the mirror.
Abstract:
PROBLEM TO BE SOLVED: To provide an adhering structure for an optical component and an image sensor module that read description contents of a document as less-distorted image data. SOLUTION: The adhering structure is provided for an optical component wherein a long and narrow lens unit 3 is adhered to a case 1 by an adhesive. The structure includes: one or more abutting parts 6B where the case 1 and the lens unit 3 are abutted on each other in a sub scanning direction (y); and one or more adhering parts 7B, in a portion other than the abutting parts 6B, where the case 1 and the lens unit 3 are adhered via the adhesive.
