Inventors: Oliver, Thomas C.; Rohn, David C.; Miksch, Eugene A.;
Assignee: Hewlett-Packard Company (Palo Alto, CA)
Primary Examiner: Allen; Stephone B.
Assistant Examiner:
Attorney, Agent or Firm:
A portable scanner may comprise a first image detector and a second image detector placed in spaced apart relation to the first image detector. A plurality of position detectors is located between the first image detector and the second image detector for detecting a position of the portable scanner. A portable scanner may also comprise an image detector having a first side and a second side opposite said first side. A first plurality of position detectors is located adjacent the first side of the image detector. A second plurality of position detectors is located adjacent the second side of the image detector. |

DETAILED DESCRIPTION What is claimed is: 1.
A portable scanner, comprising: a first image detector; a second image detector placed in spaced apart relation to said first image detector; and a plurality of position detectors located between said first image detector and said second image detector for detecting a position of said portable scanner.
2.
The portable scanner of claim 1, wherein said first image detector and said second image detector comprise linear arrays of photodetectors.
3.
The portable scanner of claim 1, wherein said first image detector comprises a first contact image sensor and said second image detector comprises a second contact image sensor.
4.
The portable scanner of claim 3, wherein said first contact image sensor comprises a first linear array of photodetectors, and said second contact image sensor comprises a second linear array of photodetectors, and wherein said first contact image sensor is parallel to said second contact image sensor.
5.
The portable scanner of claim 1, wherein said plurality of position detectors comprise two optical position detectors, and wherein said two optical position detectors form a line which is parallel to said first image detector and said second image detector.
6.
The portable scanner of claim 1, wherein said plurality of position detectors comprise optical imaging position detectors.
7.
The portable scanner of claim 6, wherein said optical imaging position detectors comprise two dimensional arrays of photodetectors.
8.
The portable scanner of claim 1, wherein said plurality of position detectors comprise mechanical position detectors.
9.
The portable scanner of claim 1, wherein said plurality of position detectors comprises two position detectors.
10.
The portable scanner of claim 1, wherein said first and second image detectors comprise charge coupled devices.
11.
The portable scanner of claim 1, wherein said first and second image detectors comprise CMOS devices.
12.
The portable scanner of claim 1, further comprising a printed circuit board, wherein said first and second image detectors and said plurality of position detectors are mounted on and electrically connected to said printed circuit board
