Abstract: An image reading apparatus of a contact image sensor type includes an area light source. The image reading apparatus is used for reading a light transmitting original placed on an original base by irradiating light thereto from the area light source and receiving transmission light. The original base has an uneven portion on a front surface on the side on which the light transmitting original is placed so that the adhesion of the light transmitting original to the original base is prevented upon placing the light transmitting original on the original base. The uneven portion does not effect optical characteristics for reading the light transmitting original.

Abstract: A height adjustment structure for an image-scanning device. The scanning device has a guiding rod, an optical system and a document panel. The guiding rod and the document panel are fixed relative to each other. The optical system includes a box body and an axial rod bearer that can slide along into the guiding rod. The height adjustment structure includes a first positioning section and a second positioning section. The first positioning section is attached to one side of the box body and the second positioning section is attached to one side the axial rod bearer that faces the first positioning section. The first positioning section and the second positioning section has hooking mechanism, screwing mechanism or teeth-meshing mechanism for fixing the box body relative to the axial rod bearer and hence setting the distance from the box body to the document panel.

Abstract: An image reading apparatus includes a line light source having a light guide plate and red-, green-, and blue-LEDs, for a light transmitting original, and a contact image sensor unit for detecting light from the line light source. The light transmitting original is arranged between the line light source and the contact image sensor unit. The light transmitting original is read by moving the line light source and the contact image sensor unit relative to the light transmitting original. The line light source is moved interlockingly with the contact image sensor unit by the attraction between a magnet provided at both ends of the line light source in the longitudinal direction thereof and a magnet provided at both ends of the contact image sensor unit in the longitudinal direction thereof.

Abstract: The invention is adapted to output readings from the image board within a scanner to an operating panel. This allows the adjustment of the optical axis of the scanner to be made independently while confirming the displayed output values. Thereby, in an apparatus for scanning an original document using CCD line sensors, the adjustment of the reading optical axis of the CCD line sensors can be made without using any special equipment.
