ABSTRACT:
An image reading apparatus comprises an original table, a lamp located above the original table and used as a first light source for irradiating light to an original placed on the original table, 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 original or the light reflected therefrom, 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 the original which is 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 the original which is of the type from which light is reflected.
