Abstract
PURPOSE: To obtain a record picture featuring a high gradation without lowering the resolution very much by memorizing the output of the line memory into the secondary picture signal memory with every line and then applying the picture signal voltage while giving the sequential switching to the contents of the signal memory to the plural elements of the multi-electrode.
CONSTITUTION: The output sent from line memory 22 is processed at process circuit 17 with every line to produce the secondary picture signals which are memorized in secondary picture signals memories 18a∼18d. To record the secondary picture element of the 1st line, memory 18a is selected via memory switching circuit 19. The contents of memory 18a is supplied to the scanning circuit, where the picture signal voltage is applied along with the sequential switching given to the contents of memory 18a to each element of multi-electrode 14 through signal distribution circuit 16. Then the recording paper is run toward arrow marking 21 and by the amount equivalent to the width of one secondary picture element to be then memorized in memory 18b. Thus the electrostatic picture of a high gradation is formed on the recording paper in accordace with the picture signals. Then the recording density is controlled every secondary picture element, thus obtaining a record picture featuring a high gradation without lowering the resolution very much.
