Abstract
Abstract An electrode assembly is formed of two opposed groups of concentric selectively addressable electrodes positioned opposite a record medium. The electrode assembly is first positioned relative to the medium to produce thereon an incomplete image from an electrode of one group. Thereafter the electrode assembly is moved to a second position relative to the medium to produce the remaining portion of the selected image creating one closed image.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
195 words
Apparatus for forming a closed image on a record medium, said record medium being of the type that is responsive to stimulating elements of predetermined form for forming images thereon corresponding to the form of said elements, comprising in combination: a support means; means comprising a first group and a second group, each group comprising a plurality of selectable stimulating elements nested one within another, an element of the first group forming together with a corresponding element of the second group a closed image of predetermined form; said first group of elements being disposed on a portion of said support means and said second group of elements being disposed on another portion of said support means separated from said first portion; means for positioning said support means for positioning said first group of elements in working relationship relative to said medium and thereafter positioning said second group of elements in working relationship relative to said medium to effect the formation of an image on said medium corresponding to selected ones of said elements; and means for stimulating at least one of said corresponding elements of said first and second group while in said working relationship.
Claim 2
Dependent Claim
195 words
Apparatus for forming a closed image on a record medium, said record medium being of the type that is responsive to stimulating elements of predetermined form for forming images thereon corresponding to the form of said elements, comprising in combination: a support means; means comprising a first group and a second group, each group comprising a plurality of selectable stimulating elements nested one within another, an element of the first group forming together with a corresponding element of the second group a closed image of predetermined form; said first group of elements being disposed on a portion of said support means and said second group of elements being disposed on another portion of said support means separated from said first portion; means for positioning said support means for positioning said first group of elements in working relationship relative to said medium and thereafter positioning said second group of elements in working relationship relative to said medium to effect the formation of an image on said medium corresponding to selected ones of said elements; and means for stimulating at least one of said corresponding elements of said first and second group while in said working relationship.
Claim 3
Dependent Claim
29 words
The combination as set forth in claim 1, wherein said record medium is responsive to heat for producing an image and wherein said stimulating elements are heated when selected.
Claim 4
Dependent Claim
29 words
The combination as set forth in claim 1, wherein said record medium is responsive to light for producing an image and wherein said stimulating elements produce light when selected.
Claim 5
Dependent Claim
31 words
The combination as set forth in claim 1, wherein said medium is responsive to an electrostatic charge for creating an image and wherein said stimulating elements produce a charge when stimulated.
Claim 6
Dependent Claim
42 words
The combination as set forth in claim 1, wherein the plurality of selectable stimulating elements in each of said two groups are in the form of concentric semicircles on a common plane on said support means and open away from one another.
Claim 7
Dependent Claim
24 words
The combination as set forth in claim 5, wherein said positioning means includes means for linearly moving said support means relative to said medium.
Claim 8
Dependent Claim
24 words
The combination as set forh in claim 5, wherein said positioning means includes means for pivotally moving said support means relative to said medium.
Claim 9
Dependent Claim
60 words
The combination as set forth in claim 1, wherein said support means comprises a third group of stimulating elements which are positioned into said working relationship with said medium when the latter of said first and second groups is positioned in said working relationship, and wherein said stimulating means also includes means for selectively stimulating elements in said third group.
Claim 10
Dependent Claim
21 words
The combination as set forth in claim 1, wherein said stimulating elements are in the form of concentric arcuate shaped elements.
Claim 11
Dependent Claim
41 words
The combination as set forth in claim 1, wherein the stimulating elements in each of said groups are divided into at least two sub-groups and wherein said stimulating means further includes means for selecting all desired elements in each sub-group serially.
