Heated air blower for reducing humidity absorption in paper

摘要

A sheet repository having multiple trays and including a fan supported in a housing for receiving ambient air from outside the housing, a heating device within the housing for raising the temperature of the air conveyed by the fan, and a duct system at the outlet of the heating device for channeling the heated air. The duct system includes outlets for directing heated air onto the selected trays, and a humidity sensor provides suitable signals to shut off the heating device in order that the sheets in the trays are maintained at a uniform reduced moisture content.
