Claim 1
Independent Claim
134 words
A line scan image scanner comprising: a platen onto which a reflective original is placed; a line scan type image sensor having a line of sensor elements; a support device for supporting the image sensor so that the image sensor is rotatable from a first position in which the line of sensor elements face the platen to a second position which is about 90° apart from the platen; means for moving said support device relative to said platen so as to enable the image sensor to scan originals a line at a time; a film support device for supporting transparent film; a source of light; an optical system for projecting light from the source through the film onto the image sensor when in its second position; and means for moving the film support device.
