摘要:
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.

A liquid crystal display device includes a first and a second substrates (1, 2) disposed in parallel to each other, a liquid crystal layer (3) disposed between the two substrates (1, 2) and filled with liquid crystal, and a reflective electrode (13) having a reflective surface (13a) on which light rays coming from the outside through the first substrate (1) and the liquid crystal layer (3) are reflected towards the first substrate (1). The reflective surface (13a) of the reflective electrode (13) is undulated. The reflective surface (13a) of the reflective electrode (13) is provided with an alignment film (14B) for twisting liquid crystal molecules contained in the liquid crystal layer (3). The height of the undulation on the reflective surface (13a) of the reflective electrode (13) is smaller than at least the thickness of the alignment film (14B) at a concave portion of the undulated reflective surface (13a).

An integrated image-reading/writing head A comprises an oblong rectangular substrate (4) having a first longitudinal edge portion (4c), a second longitudinal edge portion (4d) and a surface (4a) mounted with an array of light receiving elements (2) and an array of drive IC's (80). The surface (4a) of the substrate (4) is fitted with an oblong case (1) enclosing therein the light receiving elements (2) and the drive IC's (80). The first longitudinal edge portion (4c) of the substrate (4) is extended out of the case by a predetermined width. The surface (4a) of the substrate (4) is further mounted with a light source (3) enclosed within the case (1). A plurality of heating elements (8) are mounted on a region of the surface (4a) of the substrate (4) extended out of the case (1).
摘要:
The present invention relates to a print head (3) including an illuminator (5) for emitting light in a line extending in a primary scanning direction, a liquid crystal shutter (6) for selecting whether or not light traveling from the illuminator (5) is allowed to pass, and a light emitting portion (323) for emitting light traveling from the liquid crystal shutter (6) toward a photosensitive recording medium (22). The liquid crystal shutter (6) includes a plurality of individual shutter portions aligned in the primary scanning direction, for example. Preferably, each of the shutter portions is capable of individually selecting whether or not the light traveling from the illuminator (5) is allowed to pass.
摘要:
A lens array unit (U1) comprises a first and a second lens arrays (1, 2). The first and the second lens arrays (1, 2) include respectively a plurality of lenses (11, 21), each serving as a convex lens, for formation of a non-inverted, non-magnified image. In each of the lens arrays, the lenses (11, 21) and supports (10, 20) which hold the lenses are formed integrally of a translucent resin. Therefore, manufacture of the lens array is easy.
摘要:
An image reading apparatus is provided which includes a cold-cathode tube for irradiating a linearly extending image reading section, and a plurality of light receiving elements for receiving light reflected at the image reading section. The cold-cathode tube is provided with a first end portion, a second end portion, and an intermediate portion arranged between the first end portion and the second end portion. At least one of the first and the second end portions extends in a direction differing from another direction in which the intermediate portion extends. The image reading apparatus is also provided with a suitable number of shield members for preventing relatively weak image signals supplied by the light reading elements from being adversely influenced by electrical noises.

An image scanner is provided which includes a housing, a document supporting panel fixed to the housing, a movable carriage arranged under the document supporting panel, a light source supported by the carriage for illuminating a document placed on the document supporting panel. The image scanner also includes first reflecting means supported by the carriage and second reflecting means mounted on the housing. Further, the image scanner includes third reflecting means mounted on the housing, a focusing lens supported by the carriage and a line sensor supported by the carriage.
摘要:
An image reading apparatus is provided which includes a cold-cathode tube as a light source for illuminating a document sheet, an inverter for providing the light source with driving power. A connection cable is used for electrically connecting the light source to the inverter. The image reading apparatus also includes three kinds of rows of light receiving elements arranged in the primary scanning direction for detecting the light reflected on the document sheet. A lens array is provided for focusing the reflected light at the respective rows of light receiving elements. The light receiving elements are mounted on a printed circuit board. The light source, the inverter, the lens array and the printed circuit board are supported by a single case of the image reading apparatus.
