    Abstract: 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.

    Abstract: A sensor unit and LEDs are arranged on a sensor board. A light guide is placed above the resultant structure with be parallel to the sensor. The two end portions of the light guide are bent downward at right angles, and the bent end portions serve as incident portions on which light beams from the LEDs are incident. Light entering the light guide emerges from an exit portion to be irradiated on an original. The light reflected by the original is read by the sensor. The direction in which the reflected light is incident on the sensor is parallel with the direction in which the light from each LED is incident on the incident portion. With this structure, in the image sensor, electrical connection between the LEDs, the sensor unit, and an external system is facilitated.

    Abstract: A sheet with a thickness .DELTA.x is attached on a surface of a plate glass in an image reading area, against which a subject-sheet is pressed, so that an air layer of thickness .DELTA.x can be formed between the surface of the plate glass and a surface of the subject-sheet at the opposite side. The thickness .DELTA.x is determined to reduce the effects of an optical interference of the illumination light from a light emitting diode. The sheet has an uneven surface in order to decrease an area where the sheet is in contact with the subject-sheet, thus reducing the adhesion between the sheet and the subject-sheet. A member with a low coefficient of friction is used as the sheet.
