Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
107 words
A cleaning apparatus for cleaning an erasable paper having a surface which has been treated with a releasing agent and on which a pattern of a heat-soluble ink has been printed, comprising: an adhesion roller having an outer surface made of a heat-soluble resin which has been placed in a tacky state by heating; and a platen for pressing said erasable paper onto the outer surface of said adhesion roller; said adhesion roller rotating to transport said erasable paper inserted between the outer surface of said adhesion roller and said platen while peeling off the pattern of the heat-soluble ink from the surface of said erasable paper.
Claim 2
Dependent Claim
107 words
A cleaning apparatus for cleaning an erasable paper having a surface which has been treated with a releasing agent and on which a pattern of a heat-soluble ink has been printed, comprising: an adhesion roller having an outer surface made of a heat-soluble resin which has been placed in a tacky state by heating; and a platen for pressing said erasable paper onto the outer surface of said adhesion roller; said adhesion roller rotating to transport said erasable paper inserted between the outer surface of said adhesion roller and said platen while peeling off the pattern of the heat-soluble ink from the surface of said erasable paper.
Claim 3
Dependent Claim
25 words
A cleaning apparatus according to claim 1, wherein the heat-soluble resin of the outer surface of said adhesion roller is a toner used in electrophotography.
Claim 4
Dependent Claim
114 words
A printer comprising: a cleaning unit for cleaning an erasable paper having a surface which has been treated with a releasing agent and on which a pattern of a heat-soluble ink has been printed; and a printing unit for effecting printing on the erasable paper passed through said cleaning unit by an electrophotographic method; wherein said cleaning unit comprises: an adhesion member having a surface made of a heat-soluble resin which has been placed in a tacky state by heating; and a means for pressing said erasable paper onto the surface of said adhesion member whereby said adhesion member peels off the pattern of the heat-soluble ink from the surface of said erasable paper.
Claim 5
Dependent Claim
114 words
A printer comprising: a cleaning unit for cleaning an erasable paper having a surface which has been treated with a releasing agent and on which a pattern of a heat-soluble ink has been printed; and a printing unit for effecting printing on the erasable paper passed through said cleaning unit by an electrophotographic method; wherein said cleaning unit comprises: an adhesion member having a surface made of a heat-soluble resin which has been placed in a tacky state by heating; and a means for pressing said erasable paper onto the surface of said adhesion member whereby said adhesion member peels off the pattern of the heat-soluble ink from the surface of said erasable paper.
Claim 6
Dependent Claim
134 words
A printer comprising: a cleaning unit for cleaning an erasable paper having a surface which has been treated with a releasing agent and on which a pattern of a heat-soluble ink has been printed; and a printing unit for effecting printing on the erasable paper passed through said cleaning unit by an electrophotographic method; wherein said cleaning unit comprises: an adhesion roller having an outer surface made of a heat-soluble resin which has been placed in a tacky state by heating; and a platen for pressing said erasable paper onto the outer surface of said adhesion roller; said adhesion roller rotating to transport said erasable paper inserted between the outer surface of said adhesion roller and said platen while peeling off the pattern of the heat-soluble ink from the surface of said erasable paper.
Claim 7
Dependent Claim
134 words
A printer comprising: a cleaning unit for cleaning an erasable paper having a surface which has been treated with a releasing agent and on which a pattern of a heat-soluble ink has been printed; and a printing unit for effecting printing on the erasable paper passed through said cleaning unit by an electrophotographic method; wherein said cleaning unit comprises: an adhesion roller having an outer surface made of a heat-soluble resin which has been placed in a tacky state by heating; and a platen for pressing said erasable paper onto the outer surface of said adhesion roller; said adhesion roller rotating to transport said erasable paper inserted between the outer surface of said adhesion roller and said platen while peeling off the pattern of the heat-soluble ink from the surface of said erasable paper.
