Abstract

PURPOSE: To simplify the circuit constitution and to reduce the number of elements used, by constituting the control circuit of data terminal unit with a plurality of 1 chip microcomputers μC and performing giving and reception of information between μC's.
CONSTITUTION: The control circuit 10 of data terminal unit is constituted with four one chip μC1WμC4. The μC1 is connected to the line 12 via the connection circuit 11 and the operation section 14 via the connection circuit 13. The μC2 is connected to the keyboard 16 via the connection circuit 15, μC3 is connected to the printer 18 via the drive circuit 17, and μC4 is connected to the paper tape reader 20 via the drive circuit 19 and to the paper tape punch 21 via the drive circuit 21. The giving and reception of information between μC's is made serial signal. Thus, the program for each one chip μC mainly handles the corresponding unit, the processing ability can be scattered, the program architecture is simple and easy for production, the circuit constitution is simplified and the number of elements used is decreased.
