ABSTRACT:
In an image sensor including a light emitting element for emitting a light beam to be incident on a document, a light receiving element for receiving the light beam reflected by the document, and a lens array for directing the reflected light beam from the document to the light receiving element, there is located a mirror between the lens array and the light receiving element for changing the direction of the light beam passing through the lens array. The light emitting element and the light receiving element are located on the same substrate. With this arrangement, a compact and inexpensive image sensor can be achieved. This compact image sensor causes an increased amount of light to be incident on the document.
