Abstract
Abstract A disposable cassette fits in a facsimile recorder with a moving electrode which yieldingly opposes a blade electrode and traverses the blade as electrical signals mark an electrolytic recording web. A supply roll of the moist electrolytic recording paper confined in the cartridge is drawn at very low speed along a passage between the moving and blade electrode. A resilient member in the cassette displaces the paper from contact with the blade electrode except where the moving electrode opposes the blade electrode.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
An electric graphic recording cassette detachably fitting a recorder having a scanning electrode cooperating with a linear electrode in a recording zone, the cassette comprising: a housing including a moist recording web supply compartment and guide means forming an exit path for the web through the recording zone, the housing having an opening at the recording zone admitting the scanning electrode thereto, and the guide means including means urging the web toward the opening and into the recording zone, and a resilient member extending along the recording zone and having a free flexing end closely adjacent the zone and biased yieldingly to displace the web out of the recording zone away from the linear electrode, the scanning electrode resiliently urging the web into contact with the linear electrode against the yielding displacement of the resilient member only at the effective recording spot where the scanning electrode opposes the linear electrode.
Claim 2
Dependent Claim
150 words
An electric graphic recording cassette detachably fitting a recorder having a scanning electrode cooperating with a linear electrode in a recording zone, the cassette comprising: a housing including a moist recording web supply compartment and guide means forming an exit path for the web through the recording zone, the housing having an opening at the recording zone admitting the scanning electrode thereto, and the guide means including means urging the web toward the opening and into the recording zone, and a resilient member extending along the recording zone and having a free flexing end closely adjacent the zone and biased yieldingly to displace the web out of the recording zone away from the linear electrode, the scanning electrode resiliently urging the web into contact with the linear electrode against the yielding displacement of the resilient member only at the effective recording spot where the scanning electrode opposes the linear electrode.
Claim 3
Dependent Claim
43 words
A cassette according to claim 1 wherein the housing contains a supply of moist electrolytic recording web in the compartment and path, the resilient member being biased to displace the web toward the scanning electrode opening out of contact with the linear electrode.
Claim 4
Dependent Claim
35 words
A cassette according to claim 1 including an elongate aperture admitting the linear electrode into the housing and elastomeric means on opposed edges of the aperture cooperating with the linear electrode to seal the opening.
Claim 5
Dependent Claim
153 words
An electric graphic recorder for marking a recording web comprising: a base, means on the base for holding a supply of recording web, feed means for drawing the web through the recording zone, means for guiding the web on a path through the zone, the guide means including means urging the web toward the opening and into the recording zone, a linear electrode and a scanning electrode on opposite sides of the web at the recording zone cooperating to mark the web, and a resilient member extending along the recording zone and having a free flexing and closely adjacent the zone and biased yieldingly to displace the web out of the recording zone away from the linear electrode, the scanning electrode resiliently urging the web into contact with the linear electrode against the yielding displacement of the resilient member only at the effective recording spot where the scanning electrode opposes the linear electrode.
Claim 6
Dependent Claim
