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:
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 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.

An image sensor is provided for reading images on an image carrying paper irradiated by light emitted from a light source. The image sensor includes a plurality of image sensor chips for receiving reflected light from the image carrying paper for output of image signals in accordance with the luminous energy of the reflected light. The image sensor also includes a light detector for receiving light directly from the light source for output of a detection signal in accordance with the luminous energy of the directly received light.
摘要:
The image processing apparatus (B) includes an integrated image-reading/writing head (A), platen rollers (P1, P2) for a document and a recording paper, and data processor (7) performing data processing necessary for copying an image on the document. The integrated image-reading/writing head (A), a plurality of light receiving elements (20) and a plurality of printing elements (8) are mounted on the same surface of a substrate (4). If the document (D) and the recording paper (K) are fed in the same direction, when the image on the document is copied, the pixel data outputted for the printing are arranged in the order of first to n-th. If the document (D) and the recording paper (K) are fed in opposite directions to each other, the pixel data outputted for the printing are arranged in the order of n-th to first.
