Abstract

PURPOSE:To obtain an inexpensive device with simple constitution by reading stored data showing the light and shade of each picture element synchronizing with the repetitive scanning of a recording head and by forming bots with the drive output that corresponds to the weight of a bit. CONSTITUTION:Respective (n)-bit data showing the light and shade of each picture element are selectively stored by one it each at a time synchronizing with (n) times repetitive scanning of recording head H, and they are read out to form a dot with the drive output that corresponds to the weight of the bit. For example, the composite video signal of the television screen is inputted to input terminal V, divided into eight by A-D converting circuit CV according to the level, and converted into three-bit data. This data is stored in 1024-bit memory circuits M1- M8, and recording head H on the discharge destruction system having eight pin electrodes W is driven via gate circuit G and driving circuit DR by reading the contents of those memory circuits to form eight couples of recording pictures each by performing scan three times.
