Abstract
Abstract A data terminal system is disclosed comprising a housing having an aperture through which a flexible record sheet may exit, a first cathode ray tube mounted within the housing, and conductive means for transmitting an input signal to the first and second cathode ray tubes. The system further comprises a photoconductive plate having first and second sides, optic means for projecting an optical image displayed by the second cathode ray tube onto the first side of the photoconductive plate, a conductive base plate mounted in spaced juxtaposition with the second side of the photoconductive plate, the conductive base plate and the photoconductive plate defining an image transfer station therebetween, and means for applying a voltage across the second side of the photoconductive plate and the conductive base plate. The system further comprises first feed means for intermittently feeding successive portions of an elongated strip of flexible dielectric-coated paper upon which a latent electrostatic image may be formed into the image transfer station, means for severing the successive portions of the elongated strip of flexible dielectric paper into individual flexible record sheets, toner means for developing the latent electrostatic images after the successive portions of the elongated strip of flexible dielectric-coated paper have been severed into individual record sheets, and second feed means for intermittently feeding the individual flexible record sheets from the image transfer station through the toner means and out through the housing aperture. Inverting means for inverting record sheets moving within the system''s housing in a generally horizontal direction towards the exit aperture are also disclosed. The inverting means comprises a set of parallel rollers disposed in mutual engagement substantially parallel a generally upright housing front member which defines the exit aperture. At least one of the rollers is linked by a transmission drive means with a motor disposed within the system housing. The inverting means further comprises guide means for guiding the flexible record sheets moving in a generally horizontal direction upwardly into engagement with the set of rollers, and baffle means including a generally upright baffel disposed above the set of rollers in spaced juxtaposition with the upright housing front member.
