Abstract
A recorder segment electrode assembly is pivotably mounted to an access cover of an electrographic recorder in such a manner that the segment electrode assembly is in a first protected and inoperative position when the cover is open. When the cover is closed, the segment electrode assembly is caused to pivot to a second extended and operative position in contact with recording paper.

An electrographic segment electrode mounting assembly supportable in a cover for a base of an electrographic printer to dispose electrographic electrodes in a first protected and inoperative position when the printer cover is open and in a second operative position when the printer cover is closed with respect to the base of the printer, comprising:
- a segment electrode assembly;
- support means pivotable about a fixed axis for mounting the segment electrode assembly to an electrographic printer cover movable between an open position and a closed position;
- frame means for encompassing the segment electrode assembly in a first protected and inoperative position when the cover is open;
- biasing means cooperatively mounted between the segment electrode assembly and the electrographic printer cover to maintain the segment electrode assembly in the first protected and inoperative position when the cover is open;
- and
- actuating means for moving the segment electrode assembly from the first protected and inoperative position to the second operative position when the cover is closed.
An electrographic segment electrode mounting assembly supportable in a cover for a base of an electrographic printer to dispose electrographic electrodes in a first protected and inoperative position when the printer cover is open and in a second operative position when the printer cover is closed with respect to the base of the printer, comprising:
- a segment electrode assembly including a plurality of elongated extensions;
- support means for mounting the segment electrode assembly to an electrographic printer cover movable between an open position and a closed position;
- a structure of walls affixed to the cover and surrounding the periphery defined by the segment electrode elongated extensions for encompassing the segment electrode assembly in a first protected and inoperative position when the printer cover is open;
- and
- actuating means for contacting and moving the segment electrode assembly from the first protected and inoperative position to the second operative position when the cover is closed.
