Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
A cassette for a facsimile recorder including a scanning electrode for marking a web drawn from the cassette, the cassette comprising: a housing for holding a supply of recording web including a web holding supply compartment and two opposed lips of sheet material extending outwardly from said web holding supply compartment and forming a web exit path from the compartment, the lips being connected to each other at each side of the exit path, and a ridge formed on at least one lip, said ridge being disposed on said lip intermediate the supply compartment and the exit and extending across the web path so as to urge said one lip toward the other lip and press against the web therebetween, whereby said lip is strengthened and back tension is applied to the recording web and the cassette is sealed against the escape of moisture from the web supply compartment.
Claim 2
Dependent Claim
