Abstract
The document conveying device (2) for use in a scanner (1) or the like comprises a conveyor belt (3) arranged to convey a document (4) between an outer surface (5) of the conveyor belt and a flat surface (6). The conveyor belt (3) has an inner surface (9) supported by a first and a second roller (10, 11). Each of the first and second rollers (10, 11) is supported at three or more positions along its length in order to at least partially counteract forces from the conveyor belt (3) tending to deflect said roller.
