PURPOSE:To simplify wiring by common use and to multiply the programmes to be prosecuted by selectively operating the programme assigning switch and comparing the level signal which is output by the switch operation with different reference levels. CONSTITUTION:A plurality of switches 2 to 5 and 6 to 8 of a programme assigner 1 are selectively operated for prosecuting a desired programme. For example, if a switch 2 for assigning the entirely automatic operation programme is switched on, the resistance Ro between the other end of a switch 5 and the negative electrode of the control power source is impressed with more than a quater of the control voltage. On the other hand, as the circuit which is impressed with a reference voltage lower than the quarter of the control voltage among comparison circuits C1-4 is only the circuit C4, only the circuit C4 provides outputs and thereby only the output terminal X3 becomes of a logical level 1. According to such a constitution, most part of wiring can be used commonly and thus the wiring and assembling is much facilitated. |
