Patent number: 7428084Abstract: A scanner has a transport system for transporting a document along a transport path for scanning by at least a first camera. A first removable image guide is disposed between the first camera and a first side of the document. The first removable image guide has a first manifold with a first patter of holes for applying a first level of air pressure or vacuum to the document. Replacement of the first removable image guide with an upgrade removable image guide provides an alternate manifold with an alternate pattern of holes that provide a second level of air pressure or vacuum to the document, different from the first level.Type: GrantFiled: January 23, 2004Date of Patent: September 23, 2008Assignee: Eastman Kodak CompanyInventors: Carl J. Tesavis, Scott P. Haude

Patent number: 6219511Abstract: An image reading apparatus has a reader to read document images and has a stationary image reading position. A transporter transports a document at constant speed onto the image reading position. The transporter includes a guide member and a transport member. The guide member guides document transport and is provided adjacent to the upstream side of the document reading position in the direction of document transport by the transporter. The transport member transports a document with gripping between the guide member and itself. The transport member is provided above the guide member.Type: GrantFiled: December 26, 1997Date of Patent: April 17, 2001Assignee: Minolta Co., Ltd.Inventor: Osamu Okada

Patent number: 6041198Abstract: The focused light incident from the light source on the document to be scanned has two different lengths of light path. The shorter light path is incident on the document near the light source. The longer light path is incident on the document away from the light source with a larger light spot and scans the document at a higher speed to yield a lower resolution. The high resolution light ray reflected from the document and the low resolution light ray reflected from the document pass through a set of transmitting lenses tilted at different angles to irradiate two different sets of charge coupled device sensors.Type: GrantFiled: June 24, 1998Date of Patent: March 21, 2000Assignee: Avision Inc.Inventor: Philip L.

Patent number: 6023598Abstract: An automatic document feeder for a copier has the position for reading the image of an original fed by the automatic document feeder disposed near the rear edge of the original table of the copier. In this automatic document feeder, essential parts such as a pickup roller, etc., for feeding originals to the reading position of the original table are arranged concentratedly on the rear side of the copier. Therefore, the center of gravity of the automatic document feeder resides near the rear side of the copier. This automatic document feeder is hinged at the rear side of the copier so as to cover the top surface of the original table in an openable and closable manner. Accordingly, the automatic document feeder is opened and closed with respect to the top of the copier, at a pivot which resides on the rear side near the center of gravity thereof.Type: GrantFiled: January 13, 1999Date of Patent: February 8, 2000Assignee: Sharp Kabushiki KaishaInventor: Michiaki Nishimura

Patent number: 5978614Abstract: An image scanner arrangement having a scanner, a document feeder scanning portion and a flat scanning bed. A single white plate is provided between the document feeder scanning portion and flat bed. Before scanning, the scanner scans the white plate to provide image data for testing. If this image data contains white pixels not less than 90%, a controller determines that a lamp of a light source of the scanner illuminates appropriately. After confirming that the light source is in a good condition, the scanning starts. The single white plate is utilized regardless of scanning being performed with the document feeder scanning portion or the flat scanning bed.Type: GrantFiled: March 24, 1998Date of Patent: November 2, 1999Assignee: Murata Kikai Kabushiki KaishaInventor: Shigeki Takeuchi
