/F is connected to the sliding door input mentioned above, and the Q output is connected to another p-type F/F1.
8F7) is connected to the D input and one input of the NOR gate 2°, and the Q output of the D type F/F 17 is connected to one input of the NOR gate 19. The Q output of the D-type F/F 18 is connected to the other input of the NOIt gate 19, and the Q output is connected to the NOR gate.
20. The output of the NOR gate 19 is connected to the input of a delay circuit 22 consisting of two imparks, two resistors, and a capacitor, and its output is connected to the D input of the D-type F/F 31 and the output of the delay circuit 23. It is connected. The output of the NOR gate 20 is connected to the input of a delay circuit 21 having the same configuration as the delay circuit 22, and its output is connected to the input of the delay circuit 23, the D input of the D-type F/F 43, and the output of the delay circuit 24. , the Q output of the D-type flip-flop 31 is connected to the input of the delay circuit 24 and the resistor 41 connected to the base of the L transistor 44 in the coil switching means 6, and the Q output of the D-type F/F 42 is connected to the oscillation control means. The transistor 44 is connected to a resistor 40 connected to the base of a transistor 45 within θ, the collector of the transistor 44 is connected to one end of a relay coil 43, and the emitter is grounded.
