ABSTRACT:
An image reading apparatus comprises an original table, a white plate located above the original table and having a predetermined light transmissivity and a predetermined light reflectivity, a lamp located above the white plate and used as a first light source for irradiating light to an original, placed on the original table, through the white plate, another lamp located below the original table and used as a second light source for irradiating light to the original, and a photoelectric converter for receiving the light passing through the white plate and the original, or the light reflected from the original, and converting the light into electric signals. Upon the pushing of a passing-light mode key incorporated in a console panel, the first light source is turned on and is moved, together with the photoelectric converter, in a straight line along the original table, in order to read the image formed on an original of the type through which light passes. Alternatively, when a reflected-light mode key is depressed, the second light source is turned on and is moved, together with the photoelectric converter in a straight line along the original table, in order to read the image formed on an original of the type from which light is reflected.
