EDGE EMISSION TYPE EL PRINTER

摘要

PURPOSE:To realize conservation of power of a common driver circuit driving edge emission type EL elements connected to a line head by a high voltage pulse. CONSTITUTION:A plurality of common drivers 291-29i are connected to a line head 20 through switching means 301-30i and a circuit change-over means driving these members 291-29i, 301-30i in a time sharing manner is provided to stop other common drivers during the operation of one common driver 29.
