Abstract
PURPOSE: To enable the control with high safety, by checking the coincidence of the output between the full adder circuit and that of constant generation circuit and outputting the coincidence signal if in agreement to perform the sequence control for the sewing machine control system.
CONSTITUTION: When a power supply is applied, the oscillation circuit 3 is oscillated, and the logical sum 2 between the address signal 1 and the counter output is taken, the output is input to the static memory circuit 5, the output of the circuit 5 is fed to the full adder circuit 7, and the output of the circuit 5 is integrated and fed to the coincidence check circuit 9. Further, at the circuit 9, the coincidence check for the output of the full adder and the output of the constant generation circuit 10 is made. If in agreement, the coincidence signal 12 is output and the control system of sewing machine enters the sequence control. If in disagreement, the disagreement signal 13 is output to inhibit the entering of sequence control. Thus, the control with high safety can be made.
