Abstract
Abstract A drier comprises a heater disposed behind a guide plate for drying, a heat reflecting plate for reflecting the heat from the heater toward the guide plate and means for transporting sensitive paper in sliding contact with the guide plate after the paper has been passed through the developing station. The transport means serves to absorb moisture evaporating from the sensitive paper while the paper is moved at a high speed so as to dry the paper rapidly and thoroughly.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
In a drier to be used in a copier of the wet type for drying sensitive paper while the sensitive paper is passed through a path in the drying station after it has been developed in the developing station, a structure comprising an outwardly curved guide plate for drying, having an outer surface and an inner surface, a heater disposed behind and proximate to said guide plate inner surface and adapted to impart conductive heat and intense radiant heat to said guide plate, a reflecting plate disposed behind and spaced rearwardly from said heater and being shaped and surfaced to reflect substantially all the radiant heat incident thereon from said heater toward said guide plate inner surface, and means for transporting the sensitive paper along said outer surface of said guide plate in sliding contact therewith, said transport means including an endless belt having heat resisting and hygroscopic properties for transporting the sensitive paper along the surface of said guide plate in sliding contact therewith and means for driving said endless belt.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
66 words
The drier as set forth in claim 1 wherein said guide plate for drying is curved outwardly with a suitable radius of curvature for effectively receiving the heat produced by said heater directly from said heater and as reflected by said reflecting plate and said transport means is adapted to transport the sensitive paper along the curved surface of said guide plate in sliding contact therewith.
Claim 4
Dependent Claim
21 words
The drier as set forth in claim 2 wherein said guide plate for drying is formed with indentations in its surface.
