Patent number: 6580065Abstract: A light diverting channel for use in a scanner. The channel is incorporated into the cover of a flat bed scanner and transmits light from the lamps positioned longitudinally along the scanner, up through the side of the channel, and through a central region or sheet of the channel, and then down through objects to be scanned. The light diverting channel thereby more efficiently uses the light generated by the lamps and more evenly disburses the light over and through the object to be scanned.Type: GrantFiled: October 22, 2001Date of Patent: June 17, 2003Assignee: Microtek International, Inc.Inventor: Loi Han
