Abstract

PURPOSE: To prevent disturbance in the case when mounting and demounting printing wiring circuit, by providing the printing wiring circuits with a disturbance preventive signal generating function.
CONSTITUTION: Printing wiring circuits 4W6, to which a 1st control function, a 2nd control function and a supervising control function are housed, are inserted into a printing wiring circuit housing panel of a controller 1. If a 1st control wiring circuit is contraction backed and the printing wiring circuit 4 is removed, the signal is sent to a supervising controller 3 by a disturbance preventive signal 7, and the supervising controller 3 logically separates the 1st control function. The disturbance preventive signal 7 is prepared by contact pieces 12, 13, and the printing wiring circuits are automatically prepared by the mounting and demounting of the circuits, thus positively preventing disturbance as compared to the case when operators prepare the signal from the operating panel 6.
