Abstract
A facsimile recorder for marking electro-sensitive paper including a housing with a base and a cover and a platform disposed within the housing for receiving a cassette which contains a web of paper stored as a roll. A scanning electrode is disposed within the housing in front of the platform and a linear electrode is operatively disposed relative to the scanning electrode. The linear electrode is arranged substantially normal to the path of the paper and parallel to the axis of the paper roll. The cassette is held parallel to the linear electrode by means of a plate which extends from the cover and engages the face of the cassette. Through this arrangement, the paper is withdrawn from the cassette precisely normal to the linear electrode and high quality graphic images are produced on the paper without jamming or misalignment.

A graphic electric recorder for marking an electrosensitive recording paper, said recorder comprising:
- a housing including a base and a cover and a rear wall disposed on the base;
- a platform disposed within said housing for receiving a cassette containing a roll of recording paper;
- scanning electrode means disposed within said housing and in front of said platform;
- linear electrode means disposed in operative relationship with said scanning electrode, said linear electrode means being arranged substantially normal to the path of paper being withdrawn from a cassette and substantially parallel to the rear wall;
- feed roll means disposed in front of the electrodes, said feed roll means being disposed substantially parallel to the roll of recording paper and adapted to withdraw said paper from a cassette;
- means on the housing for engaging a cassette to align the roll of recording paper substantially parallel to the linear electrode and for holding said linear electrode.
A graphic electric recorder for marking an electrosensitive recording paper, said recorder comprising:
- a housing including a base and a cover;
- a platform disposed within said housing for receiving a cassette containing a roll of recording paper;
- scanning electrode means disposed within said housing and in front of said platform;
- feed roll means disposed in said housing, said feed roll means being disposed substantially parallel to the roll of recording paper and arranged to withdraw said paper from a cassette;
- scanning electrode means disposed within said housing and between said cassette and a feed roll means;
- linear electrode means disposed in operative relationship with said scanning electrode, said linear electrode means being arranged substantially normal to the path of paper being withdrawn from a cassette and substantially parallel to the roll of paper, alignment means on the cover of the housing for engaging the cassette to align the roll of recording paper substantially parallel to the linear electrode, said linear electrode being carried on said alignment means whereby when said cover is closed, said alignment means will engage the cassette and force it into place on said platform and simultaneously dispose said linear electrode into the parallel relationship with said paper supply roll.
