ABSTRACT:
An image reading apparatus for reading indicia on the front and back surfaces of a document using two image sensors includes a document detection sensor to detect the document, a first image sensor for reading an image on one surface of the document, a second image sensor for reading an image on the other surface of the document, and a controller. The controller starts to read the image data from the first and second image sensors when prescribed amounts of time have passed after the document detection sensor detects the leading edge of the document, and stops the reading of the image data from the image sensors. The structure provides a lightweight and compact apparatus while reducing image noise caused by the mutual interferences of the light sources in reading the image data.
