Total Claims: 10
Claim 1
Independent Claim
50 words
- A hand-held scanner for sensing non-coded images on a substrate, characterized in that it comprises!. a group of light sensitive elements for sensing the light patterns of said images as the scanner is moved across said substrate, and means for sensing the translational velocity and rotation of said scanner.
Claim 2
Dependent Claim
50 words
- A hand-held scanner for sensing non-coded images on a substrate, characterized in that it comprises!. a group of light sensitive elements for sensing the light patterns of said images as the scanner is moved across said substrate, and means for sensing the translational velocity and rotation of said scanner.
Claim 3
Dependent Claim
65 words
- The scanner of claim 1 characterized in that said velocity sensing means comprises an X-Y coordinate reference grid, means for sensing the rectilinear components of movement of a first position on said scanner with respect to the X lines in said grid, and means for sensing the rectilinear component of movement of a second position with respect to the Y lines in said grid.
Claim 4
Dependent Claim
38 words
- The scanner of claim 2 characterized in that it further includes means for sensing the rectilinear component of movement of a third position on said scanner with respect to one set of said lines of said grid.
Claim 5
Dependent Claim
39 words
- The scanner of claim 3 characterized in that it further includes means for sensing the rectilinear component of movement of a fourth position on said scanner with respect to the other set of said lines of said grid.
Claim 6
Dependent Claim
21 words
- The scanner of claim 4 characterized in that at least said first and second positions are adjacent to each other.
Claim 7
Dependent Claim
144 words
- The scanner of anyone of claims 2 to 5 characterized in that said reference grid is superimposed over at least part of said image and the X lines in said grid are of a first color and the Y lines in said grid are of a second color, said means for sensing the movement of said first position with respect to said X lines comprises first photoconductive means fixed to said scanner at said first position, and a first monochromatic band pass filter passing only light of said first color to said first photoconductive means, and said means for sensing the movement of said second position with respect to said Y lines comprises second photoconductive means fixed to said scanner at said second position, and a second monochromatic band pass filter passing only light of said second color to said second photoconductive means.
Claim 8
Dependent Claim
43 words
- The scanner of claim 6 characterized in that said light sensitive elements for sensing said non-coded images comprise a group of photoconductive elements and band stop filters preventing the passage of said first and second colors to said group of photoconductive elements.
Claim 9
Dependent Claim
61 words
- The scanner of claim 7 characterized in that it further includes means for sensing the movement of a third position on said scanner with respect to said X lines comprising third photoconductive means fixed to said scanner at said third position, and a third monochromatic band pass filter passing only light of said first color to said third photoconductive means.
Claim 10
Dependent Claim
61 words
- The scanner of claim 8 characterized in that it further includes means for sensing the movement of a fourth position on said scanner with respect to said Y lines comparing fourth photoconductive means fixed to said scanner at said fourth position, and a fourth monochromatic band pass filter passing only light of said second color to said fourth photoconductive means.
