    Abstract: In a contact-type image sensor according to the present invention, a protrusion is formed in a transparent plate, a recess is formed in a sensor frame, and the transparent plate is engaged with the sensor frame so that the heights of surfaces of the transparent plate and the sensor frame on sides of conveying a manuscript are substantially the same. In conventional techniques, it was necessary to bend a manuscript conveying path because of different heights of a protrusion of the frame and the transparent plate. Further, even though the heights of the sensor frame and the transparent plate are the same, a contact portion therebetween forms an angle, whereby a contact surface is not brought into close contact alone an entire length of an image sensor, and gaps are partially formed in the contact surface. Therefore, at time of cleaning a surface of the transparent plate using a solvent such as alcohol to remove dirt on the transparent plate, the solvent and extraneous matters intrude inside the image sensor from the gaps, a passage of light is obstructed, and therefore light-and-shadow information of an image of the manuscript was not correctly transmitted to sensor.

    Abstract: A size-reduced image reading apparatus for optically reading an image drawn on the document surface. The size reduction is achieved this way. Two light sources are so mounted over the document surface at a specific angle formed with the document surface that they are a certain distance away from each other and bilaterally symmetrical. These light sources are surface light emitters made by forming a light-emitting layer on a transparent substrate. And a fiber lens formed of a plurality of bundles of optical fibers is mounted in the gap between the two surface light emitters. Even if the surface light emitter is brought close to the reading position, a uniform illuminance intensity can be obtained at this reading position. Furthermore, if a fiber lens with a small diameter is used in place of the rod lens, the conjugate length can be shortened.
