Abstract

PURPOSE: To make it possible to exactly control a printing copy area, by dividing a printing copy signal having high frequency by the external circuit, stepping it down to frequency which can be counted by a microcomputer, and controlling a printing area on the recording paper by the microcomputer.
CONSTITUTION: A printing copy signal having high frequency is divided by the external TTL circuit, it is stepped down to frequency which can be counted by a microcomputer, and an area which is not printed, and a recording area are controlled by the microcomputer 16. Namely, when the printing copy signal is input to the CK terminal of the shift register 10, a signal which has divided the printing copy signal, for instance, to 1/4 is obtained by the output side of the AND gate circuit 15 so that it can be counted by the computer 16. Thus, an priting copy area can be controlled exactly by controlling a printing area on the recording paper.
