Integrated Chassis For Automatic Document Feeder In A Scanning Unit

View page
US Patent:
6433897, Aug 13, 2002
Filed:
Nov 10, 2000
Appl. No.:
09/710295
Inventors:
Darren W. Wilcox - San Diego CA
Alpha N. Doan - San Diego CA
Dennis Sonnenburg - San Diego CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
H04N 104
US Classification:
358498, 358496, 358400, 271 41, 271 1011, 271121
Abstract:
In a scanning unit such as a facsimile machine, an automatic document feeder transports individual sheets from a stack of documents along a document path over a scanning window to an output tray. An upper guide member includes an integrated chassis which provides most of the functional features required for picking individual sheets from a stack of documents in an input tray and transporting the sheet past a scanning window. The various components incorporated in the integrated chassis include a document separation mechanism, pre-scanning pinch rollers, post-scanning pinch rollers, a spring-loaded limiter with minimal paper path obstruction, a hinging mechanism to facilitate manual access to the document path, a latching mechanism, referencing datums, and ESD grounding including ESD brushes adjacent the document path and an ESD shield for a circuit board housed in the upper guide member. In the preferred form, the integrated chassis is formed from an enlarged sheet metal plate which attaches to the underside of a manual control/display panel with the circuit board sandwiched therebetween.

Dust Tolerant Windowless Scanner

View page
US Patent:
6657751, Dec 2, 2003
Filed:
Mar 7, 2000
Appl. No.:
09/521192
Inventors:
Craig A. Maurer - San Diego CA
Scott F. Williams - San Diego CA
Jon Lee Zimmerman - Escondido CA
Jack Schmidt - Carlsbad CA
Alpha Doan - San Diego CA
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
H04N 104
US Classification:
358474, 358471, 358473, 358497, 358498, 358462, 358464
Abstract:
A dust tolerant scanner without a transparent plate to support objects scanned by its media scan assembly. Other dust or debris collecting surfaces in the optical path of the scanner are positioned as far away as possible from an object focal plane of the media scan assembly. The media scan assembly includes upper and lower document feeder portions which define a media path adjacent to a reference surface of the upper portion. The lower document feeder portion includes a media conformance member which positions pieces of media against the reference surface as the pieces of media are advanced along the media path. The media conformance member includes ramp portions and an aperture which provides an optical path between the object focal plane and a sensor focal plane within the scanner.

Ink Jet Printer Having Staggered Nozzle Array For Color Printing

View page
US Patent:
20020001013, Jan 3, 2002
Filed:
Apr 21, 1998
Appl. No.:
09/063613
Inventors:
BRENT W. RICHTSMEIER - SAN DIEGO CA, US
ALPHA DOAN - SAN DIEGO CA, US
MARK S. HICKMAN - VANCOUVER WA, US
Assignee:
Hewlett-Packard Company
International Classification:
B41J002/21
US Classification:
347/043000
Abstract:
A color ink jet printer including a print carriage movable along a carriage scan axis and a plurality of color producing ink jet printheads supported by the print carriage and offset relative to each other so that their nozzle arrays are non-overlapping along the media scan axis, such that the nozzle arrays of the ink jet printheads traverse non-overlapping regions as the carriage is scanned along the carriage scan axis.

Scanning Unit With Independent Spring-Loaded Document Control Components Mounted On An Integrated Chassis

View page
US Patent:
55471790, Aug 20, 1996
Filed:
Oct 17, 1994
Appl. No.:
8/324821
Inventors:
Darren W. Wilcox - San Diego CA
Alpha N. Doan - San Diego CA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
B65H 500
US Classification:
271 32
Abstract:
In a scanning unit such as a facsimile machine, an automatic document feeder transports individual sheets from a stack of documents along a document path over a scanning window to an output tray. An upper guide member includes an integrated rigid chassis for positioning document control components adjacent the scanning window. The document control components included a central pre-scanning pinch roller, a full width hold-down limiter, and a central post-scanning pinch roller which are each mounted with their own separate biasing springs on the integrated chassis. Two elongated wire springs respectively engage both ends of the hold-down limiter, while two sets of cantilever leaf springs provide strong and weak spring biasing, respectively, to the pre-scanning and post-scanning pinch rollers.

Retractable Pin Sheet Feed Mechanism

View page
US Patent:
48654787, Sep 12, 1989
Filed:
Jul 23, 1987
Appl. No.:
7/077576
Inventors:
Lawrence W. Chan - San Diego CA
Alpha N. Doan - San Diego CA
Curt N. Torgerson - San Diego CA
Paul J. Wield - San Diego CA
Assignee:
Hewlett Packard Company - Palo Alto CA
International Classification:
B41J 1128
US Classification:
4006163
Abstract:
A retractable pin sprocket drive for feeding paper employs free floating, radially moving, cam actuated sprocket pins in axially spaced sprocket hubs forming sprocket wheels. The pins are slidably fitted in equally angularly spaced radial slots in each sprocket hub. The sprocket wheels are each journalled in a sprocket wheel housing and the sprocket pins are moved radially only by a stationary cam track in each sprocket housing as the sprocket wheels rotate. Insertion of paper having perforated edges is facilitated by means providing for the precise axial spacing of the sprocket wheels and angular positioning of the sprocket wheels and pins in relation to the perforations or holes along the edges of the paper, together with transparent sprocket wheel housings and openings therethrough permitting viewing of the sprocket pins and the holes in the paper as they come together, to permit precise sprocket pin insertion into the holes in the paper.

Inventors:
Brent W. Richtsmeier - San Diego CA
Alpha N. Doan - San Diego CA
Mark S. Hickman - Vancouver WA
Assignee:
Hewlett-Packard Company - Palo Alto CA
International Classification:
B41J 2145
US Classification:
347 40
Abstract:
A color ink jet printer including a print carriage movable along a carriage scan axis, a plurality of non-black color printing ink jet printheads supported by the print carriage and offset relative to each other so that their nozzle arrays are non-overlapping along the media scan axis, and a black printing ink jet printhead having a nozzle array that overlaps along the media axis with one of the nozzle arrays of the non-black color printing ink jet printheads, whereby as the carriage is scanned along the carriage scan axis the nozzle arrays of the non-black color printing ink jet printheads traverse non-overlapping print regions and the nozzle array of the black printing printhead traverses a print region that overlaps one of the non-overlapping print regions traversed by the nozzle arrays of the non-black color printing ink jet printheads.
