PURPOSE:To print a mark, number, etc. with a simple constitution and without increasing the transmission time, by printing the serial numbers in the scanning direction of a transmitting original and controlling the distance between digits by counting the input pulses of a pulse motor. CONSTITUTION:The step field pulses which are fed to a pulse motor (not shwon in the diagram) for feed of original are counted at a counting part (not shown in the diagram). Then a pulse is generated to turn a print 1. When the count value of the step field pulses reaches prescribed level, the voltage is produced to magnetize an electromagnet 2. Thus a transmitting original 5 and a print plate 3 are pressed to the print 1 to perform the printing. In this case, the printing direction is set the transmitting direction (secondary scanning direction). Then the input pulses of a pulse motor which feeds the original 5 are counted. Thus the distance between digits is automatically measured. |
