ABSTRACT:
Scanning errors and document feed errors are prevented by pressing originals, including thin originals and thick originals of greatly different thicknesses, to the scanning surface (1a) of an image sensor (1) with pressure appropriate for the respective original. A pressure-generating mechanism (50) is used to press the original against the scanning surface (1a) by selecting different elastic bodies with different spring forces to produce a different elastic force in accordance with the thickness of the original document.
