摘要:
An image sensor module A1 includes a case 300, a photoelectric converter 400 positioned within the case 300, and first and second optical units 100, 200 for forming an image of a subject on the light-receiving surface of the photoelectric converter 400. Imaging of the subject using the first optical unit 100, or imaging of the subject using the second optical unit 200, can be selected. It is possible to conduct a plurality of types of imaging each having a different view angle, while restricting increases in size and cost.

An image sensor module (S) includes a substrate (4) having a projecting portion (41) projecting sideways from a frame (3). The projecting portion (41) has an end (4b) provided with a plurality of terminals (81) electrically connected to an image sensor chip (5). The image sensor module (X) can be easily connected to another apparatus by inserting the end (4b) of the projecting portion (41) into a socket type connector.

A lens unit (U15) includes a housing (45), an upper and a lower lens arrays (A1′, A2′), and a first and a second prisms (4A, 4B). Each of the lens arrays includes a plurality of lenses, a light-shielding member (4), and a plurality of positioning projections, all of which are integral with each other. Downwardly traveling light which enters the housing (45) through a first slit (45c) formed at an upper portion of the housing (45) is directed upward by the first prism (4A) to pass through the two lens arrays (A1′, A2′). The light is then directed downward by the second prism (4B) to exit the housing through a second slit (45d) formed at a lower portion of the housing (45).
摘要:
An image reading apparatus is provided for reading out images printed on a document. The apparatus includes a casing elongated in the primary scanning direction and a transparent cover supported by the casing. In image-reading operation, the cover is held in sliding contact with a document at an image reading line. The apparatus further includes an insulating substrate attached to the casing, light sources for illuminating the image reading line, light sensors for receiving reflected light coming from the image reading line and a luminosity adjuster supported by the casing for equalizing luminosity along the image reading line.
摘要:
A lens array includes a plurality of lenses, a holder portion for fixing the lenses, and an acrylic transparent layer for covering the lens surfaces of the respective lenses. The holder portion and the lenses are made of the same transparent resin to be formed as a one-piece element. The lens array also includes a dark-colored light shielding layer for preventing the unwanted passage of light. The transparent layer is formed on the light shielding layer for preventing the latter from peeling off.

An image sensor unit for reading documents includes a casing elongated in the primary scanning direction, a light source, at least a pair of mirrors held in facing relation for alternately reflecting light, a lens unit for focusing light reflected on the document, and a sensor for receiving the light focused by the lens unit. For reducing the vertical dimension of the image sensor unit, the paired mirrors are spaced from each other in the secondary scanning direction within the casing.
摘要:
An image reading/writing head (1) includes an integrated circuit for reading (10) provided with a plurality of light receiving elements for reading an image on a document (D) by receiving, via optical lenses (12), light reflected by the document placed on an image reading surface provided in a surface of a casing (2); a plurality of heating elements (9) disposed in a surface different from the reading surface in the casing (2) for forming an image on recording paper by heat; and an integrated circuit for writing (11) for controlling these heating elements (9). The integrated circuit for reading (10), the heating elements (9) and the integrated circuit for writing (11) are provided in a main surface of a substrate (7) held by the casing (2), and light reflecting member (13) is provided for making the light after passing the optical lenses (12) enter the light receiving elements.
摘要:
A nozzle arrangement structure in an ink jet print head. A plurality of pressure chambers are arranged in circular form, and a plurality of nozzles receive an ink supply from the corresponding pressure chambers and are arranged in an zig zag arrangement to obtain a small interval between the dots. Two straight lines concerning the zig zag arrangement are inclined against a printing direction and a direction perpendicular to the printing direction. When an ink discharge from the nozzles is controlled, preprocessing of serial data is carried out by hardware.
摘要:
A wall-mounting image processing apparatus (A) includes a machine housing (90) mounted on a substantially vertical wall surface (H), and an image reading/writing head (X) disposed in the machine housing. The image reading/writing head (X) includes a substrate (4) having one surface (4A) on which a plurality of light receiving elements (4a) are arranged in a row. Part of said one surface (4A) forms an excess surface (49) projecting laterally from a head case (1), and the printing elements (4b) are arranged on the excess surface (49).
摘要:
A linear light source (A) including an insulating substrate (1), a plurality of light emitting elements (3) arranged in columns on the substrate (1), a wiring pattern (2) connected with the light emitting elements (3) and co formed on the substrate (1) so as to divide the light emitting elements (3) into a plurality of groups (B1 to Bn), and first and second terminal units (23a, 23b) in continuity with the wiring pattern (2). The plurality of light emitting elements (3) define a plurality of clearances (P1 to P2−1) between adjacent light emitting elements, the clearances (P P1 to P2−1) being adjusted so as to have different lengths.
