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.

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:
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 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.

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.
