    Abstract: A lens unit (U15) includes a housing (45), an upper and a lower lens arrays (A1null, A2null), 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 (A1null, A2null). 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).

    Abstract: A sensor unit and LEDs are arranged on a sensor board. A light guide is placed above the resultant structure to be parallel with 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: An image sensor has a frame including a reading window formed therein at the top of the frame. The reading window is closed by a glass covering which is adhered to the frame through an adhesive. First and second grooves are provided in the frame to extend along the reading window. After the adhesive has been charged into the first groove, the glass covering is placed and pressed against the frame top so that the glass covering will be adhered to the frame top through the adhesive. At this time, any excess adhesive may be received and held by the second groove.

    Abstract: [PROBLEMS] A light guide and a line illuminator incorporating it in which the deterioration of a read out image can be suppressed even when the document surface is floating by spreading the intensity distribution of light in the longitudinal direction at a position (document position) of an article being illuminated. [MEANS FOR SOLVING PROBLEMS] In a light guide (10) arranged such that a light entering from the end face exits from an exit face provided along the longitudinal direction while reflecting off the inner surface, a side face shape orthogonal to the longitudinal direction has a curved surface (1) of first elliptic arc, a curved surface (2) of second elliptic arc, a first exit face (3), a second exit face (4), and a light scattering part (5) formed at an elliptic focal position (or in the vicinity thereof) on the major axis plane of each ellipse. Condensing position of a light reflected off the first curved surface is different from the condensing position of a light reflected off the second curved surface.
