Embodiment Construction

[0030] figure 1 An end view of a first embodiment of a scanner 1 incorporating a document feed device 2 according to the invention is shown. The document transport device 2 comprises a conveyor belt 3 arranged for transporting documents 4 between an outer surface 5 of the conveyor belt and a flat surface 6 of a glass plate 7, by means of the CIS (Contact Image Sensor ) image scanning devices 14, 15 in the form of documents can be read through the glass plate 7. The scanner is of the type in which the transport device 2 is adapted to advance the document 4 during scanning.

[0031] By using the same conveyor belt 3 both for the transport of the document 4 and for pressing the document against the glass plate 7 some advantages are obtained. First, a very compact scanner can be provided. Second, if the pressure applied to the document against the glass plate increases, the friction between the conveyor belt 3 and the document 4 also increases and, as a result, the conveying fo...

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.

Description

technical field [0001] The present invention relates to a document conveying device used in a scanner or the like, wherein a conveying belt is arranged to convey a document between an outer surface of the conveying belt and a flat surface, and wherein the conveying belt has a The inner surface. Background technique [0002] US 6,113,091 discloses an automatic document feeder for use with an image forming device such as a flatbed scanner to feed a document on a glass plate through which the image forming device can read the document. A rotating conveyor belt presses the document against the glass plate, thereby transporting the document along the plate. A plurality of squeeze rollers squeeze the conveyor belt and thereby press the document against the glass plate. In order to keep the tension of the belt constant, the tension roller presses against the outer surface of the belt. Since the document is positioned stationary on the glass plate, an image document is formed by ...
