Abstract
Abstract In a cassette for a facsimile recorder with a moving electrode which scans across a recording web and marks the web with graphic signals electrically applied between the moving electrode and a cooperating linear electrode, the cassette has a tubular housing and a lip extending from the housing. The linear electrode is polygonally cylindrical in cross section and is attached to the underside of the cassette lip.
