Abstract: The present invention relates to an apparatus having a light source for a transparent sheet of a scanner that includes a lamp, a reflective plate, a spreading plate and a protective plate. The light rays emitted by the lamp are used to scan a transparent sheet, the reflective plate in the arc shape reflects the light rays onto the scanning platform and there is an aperture on the predetermined position of the reflective plate to decrease the illumination for distributing uniformly the light rays. Besides, the spreading plate has a plurality of perforations to advance the light rays distributed uniformly. The protective plate made of the material pervious to light protects the components of this invention. As those described above, there are many advantages for the present invention, such as the structure is simple, the cost is low, and is much practical and can highly improve the performance of a scanner for a transparent sheet.

Abstract: A photographic scanner has a light source for illuminating a photographic original to be scanned and a sensor for detecting light which has passed through the original. The sensor has a single row of sensing cells, and the original is scanned by moving the sensor and the original relative to one another in a direction perpendicular to the row. An objective serves to focus light from the original on the sensing cells. Between the objective and the sensor is a protective glass sheet which overlies the sensor. A mask is interposed between the protective sheet and the sensor and has a slit in register with the row of sensing cells. The mask reduces the amount of scattered light reaching the sensing cells.

Abstract: An image reading system for optically reading an original includes a convergent type light-emitting diode array as a light source, a white level reference and an image sensor disposed opposite to the white level reference. The light emitted from the LED array has a light intensity distribution which reduces in level in a transverse direction from an irradiation axis. The LED array is preferably so disposed with its irradiation axis passing a mid-point between the white level reference and an intersection point between an original surface travelling line and a straight line extending between the white level reference and the image sensor.
