Abstract
Abstract A pattern shaped and sized to fit adjacent the inner cylindrical surface of a transparent scanner drum, of a drum-type image scanning system is oriented to display at least one line parallel to the axis of rotation of the drum. The pattern preferably has other lines oriented to other predetermined directions. The pattern is held in place inside the drum by a coaxial lighted cylindrical pattern holder rotatable with the drum. The user aligns the original with reference to the lighted pattern for affixation as desired on the drum surface for scanning of the original image therefrom.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
113 words
Apparatus for precisely locating an image-bearing original for selectively oriented affixation to the exterior surface of a hollow, cylindrical, transparent walled drum, controllably rotatable about a predetermined axis of rotation of a drum-type image scanning system, comprising: a predetermined pattern on a thin transparent sheet of a size and shape not larger than the inside surface of said hollow cylindrical drum; and pattern supporting means for supporting said pattern within said hollow cylindrical drum, such that said pattern is supported adjacent said inside surface of said drum in a predetermined juxtaposition with said axis of rotation and rotatable with said drum for viewing of said pattern through said transparent wall of said drum.
Claim 2
Dependent Claim
113 words
Apparatus for precisely locating an image-bearing original for selectively oriented affixation to the exterior surface of a hollow, cylindrical, transparent walled drum, controllably rotatable about a predetermined axis of rotation of a drum-type image scanning system, comprising: a predetermined pattern on a thin transparent sheet of a size and shape not larger than the inside surface of said hollow cylindrical drum; and pattern supporting means for supporting said pattern within said hollow cylindrical drum, such that said pattern is supported adjacent said inside surface of said drum in a predetermined juxtaposition with said axis of rotation and rotatable with said drum for viewing of said pattern through said transparent wall of said drum.
Claim 3
Dependent Claim
42 words
Apparatus for precisely locating an image-bearing original according to claim 1, wherein: said pattern comprises at least a first line alignable parallel to said axis of rotation and at least a second line aligned at a predetermined angle to said first line.
Claim 4
Dependent Claim
23 words
Apparatus for precisely locating an image-bearing original according to claim 1, further comprising: illumination means for illuminating said pattern to facilitate said viewing.
Claim 5
Dependent Claim
44 words
Apparatus for precisely locating an image-bearing original, according to claim 1, wherein: said pattern supporting means is a cylinder whose outer radius is smaller than the inside radius of said drum by an amount at least as large as the thickness of said pattern.
Claim 6
Dependent Claim
33 words
Apparatus for precisely locating an image-bearing original, according to claim 1, wherein: said pattern supporting means is provided with a pattern-aligning reference for precise location of said pattern with respect to said axis.
Claim 7
Dependent Claim
30 words
Apparatus for precisely locating an image-bearing original, according to claim 5, wherein: said pattern supporting means is provided with pattern holding means for holding said pattern in said precise location.
Claim 8
Dependent Claim
63 words
Apparatus for precisely locating an image-bearing original, according to claim 4, further comprising: illumination means for providing illumination from within said pattern supporting means; and wherein said pattern supporting means has light transmitting walls so that said illumination is transmitted through said walls and through said pattern so as to facilitate viewing of pattern details from the outside of said transparent walled drum.
Claim 9
Independent Claim
121 words
A method for precisely locating an image-bearing original for selectively oriented affixation to the exterior surface of a hollow, cylindrical, transparent walled drum controllably rotatable about a predetermined axis of rotation of a drum-type image scanning system, comprising the steps of: marking a predetermined pattern on a thin transparent sheet of a size and shape not larger than the inside surface of said hollow cylindrical drum, said pattern containing at least one straight line; supporting said pattern within said drum in predetermined juxtaposition with said axis of rotation for viewing of at least said line through said transparent wall of said drum; orienting said original in predetermined juxtaposition with said viewed pattern; and affixing said oriented original securely to said drum.
Claim 10
Independent Claim
121 words
A method for precisely locating an image-bearing original for selectively oriented affixation to the exterior surface of a hollow, cylindrical, transparent walled drum controllably rotatable about a predetermined axis of rotation of a drum-type image scanning system, comprising the steps of: marking a predetermined pattern on a thin transparent sheet of a size and shape not larger than the inside surface of said hollow cylindrical drum, said pattern containing at least one straight line; supporting said pattern within said drum in predetermined juxtaposition with said axis of rotation for viewing of at least said line through said transparent wall of said drum; orienting said original in predetermined juxtaposition with said viewed pattern; and affixing said oriented original securely to said drum.
Claim 11
Dependent Claim
29 words
A method for precisely locating an original according to claim 8, further comprising the step of: illuminating said pattern for convenient observation of said pattern while orienting said original.
Claim 12
Dependent Claim
28 words
A method for precisely locating an original according to claim 8, wherein: said predetermined juxtaposition of said pattern places said line therein parallel to said axis of rotation.
