PURPOSE:To perform a fine pattern checking. CONSTITUTION:When a decoder 8 judges pattern data from a pattern data storage memory 3 as a rectangular or trapezoidal shape, it sends a signal to an R or S terminal of a flip-flop 9. When the flip-flop 9 subsequently receives the signal at the same terminal, it does not change its output, and when the flip-flop 9 receives a signal at different terminal immediately before, it changes its output. When the output of the flip-flop 9 is changed, a pulse generator 10 generates a pulse, and when it is not changed, the generator 10 generates a signal of a low state ('0'). A first counter 11 counts pulses generated from the generator 10. A second counter 14 counts up when the generator 10 generates a '0' signal. A calculator 15 adds the counted values of the first and second counters, and further adds '1' thereto. |
