Abstract

"Smart" enclosure units which not only isolate electronic printers from the surrounding atmosphere but prevent explosion hazardous conditions from arising when retrieving output from the printers are described. The units comprise a first pressurizable chamber for housing an electronic printer which transforms received input electronic signals into printout copy which emerges from the printer; and a second pressurizable chamber contiguous with the first chamber for receiving, through a portal located between the chambers, printout copy from the printer as the printout copy emerges from the printer. The second chamber has a door enabling an operator to periodically remove printout copy from the second chamber. A closure for the portal when open permits printout copy to pass from the printer into the second chamber. When closed, this closure seals off the first chamber from the second chamber. A pressurized atmosphere of innocuous gas is maintained in the first and second chambers when the door is in closed position and the closure is open, and a pressurized atmosphere of innocuous gas is maintained in the first chamber when the closure is in closed position. Control means permits ope…
