PROBLEM TO BE SOLVED: To control the current value to be supplied to each driven element by increasing or reducing it and to simplify the constitution or control of a microprocessor, etc., by making every switching means, corresponding one-on-one to every driven element into a current synthesizing circuit, i.e., a connection body, where N pieces of unit switching parts having almost equal current capacitance are connected in parallel to each other. SOLUTION: A data shift register part 14 consists of (m) pieces of D flip-flops 14-1 to 14-m. The binary serial data which are fetched via a data terminal 14b, every time a single pulse of a 1st clock signal is added to a 1st clock terminal 14a, are shifted, and the area equivalent to one printed line are converted into a parallel form from 9 serial form. A latch circuit array part 15 consists of latching circuits(LAT) 15-1 to 15-m of flip-flops and primarily holds the contents of each digit of the part 14 by the latch synchronizing signal that is inputted to a latch terminal 15a. Then the correction data shift register parts 16 are shifted one by one. |
