Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
183 words
A recorder for use with a chemically treated paper web comprising: a. a main body; b. a closed planar ridge portion on said main body bounding an area thereon; c. a paper storage compartment located within the area bounded by the ridge portion of said main body; d. a paper web stored in said compartment; 3. a recording apparatus located within the area bounded by the ridge portion of said main body adjacent to said paper storage compartment; f. a cover overlying said paper storage compartment and said recording apparatus and adapted to be fastened to said main body; g. sealing means in the form of a closed planar figure conforming in shape to that of the ridge portion of said main body, said sealing means being resilient and being adapted to yieldably conform to the shape of the ridge portion of said main body to effectively seal the area bounded thereby and to permit the exit therethrough of said paper web; and h. driven rolls mounted externally of said sealing means and adapted to pull said paper web through said sealing means.
Claim 2
Dependent Claim
183 words
A recorder for use with a chemically treated paper web comprising: a. a main body; b. a closed planar ridge portion on said main body bounding an area thereon; c. a paper storage compartment located within the area bounded by the ridge portion of said main body; d. a paper web stored in said compartment; 3. a recording apparatus located within the area bounded by the ridge portion of said main body adjacent to said paper storage compartment; f. a cover overlying said paper storage compartment and said recording apparatus and adapted to be fastened to said main body; g. sealing means in the form of a closed planar figure conforming in shape to that of the ridge portion of said main body, said sealing means being resilient and being adapted to yieldably conform to the shape of the ridge portion of said main body to effectively seal the area bounded thereby and to permit the exit therethrough of said paper web; and h. driven rolls mounted externally of said sealing means and adapted to pull said paper web through said sealing means.
Claim 3
Dependent Claim
28 words
A recorder as recited in claim 1, wherein a window is provided in the cover adjacent the driven rolls and outside the area bounded by the ridge portion.
Claim 4
Dependent Claim
127 words
a recording apparatus located within the area bounded by the ridge portion of said main body adjacent to said paper storage compartment; f. a cover overlying said paper storage compartment and said recording apparatus and adapted to be fastened to said main body; g. sealing means in the form of a closed planar figure conforming in shape to that of the ridge portion of said main body, said sealing means being resilient and being adapted to yieldably conform to the shape of the ridge portion of said main body to effectively seal the area bounded thereby and to permit the exit therethrough of said paper web; and h. driven rolls mounted externally of said sealing means and adapted to pull said paper web through said sealing means.
Claim 5
Dependent Claim
127 words
a recording apparatus located within the area bounded by the ridge portion of said main body adjacent to said paper storage compartment; f. a cover overlying said paper storage compartment and said recording apparatus and adapted to be fastened to said main body; g. sealing means in the form of a closed planar figure conforming in shape to that of the ridge portion of said main body, said sealing means being resilient and being adapted to yieldably conform to the shape of the ridge portion of said main body to effectively seal the area bounded thereby and to permit the exit therethrough of said paper web; and h. driven rolls mounted externally of said sealing means and adapted to pull said paper web through said sealing means.
