ヤツター用の停止装置。 a counter-type detection switch that increments a count in conjunction with the opening/closing operation of the shutter curtain by driving an electric switch, and outputs a detection signal when the count reaches a preset count value;
A rotary detection switch that outputs a detection signal when a rotating body that rotates in conjunction with the opening/closing operation passes a preset position, and both detection switches are connected, and a detection signal from only one of the detection switches is connected. The architecture is characterized in that it is configured by providing a stop judgment means for outputting a stop signal to the switch when it is determined that the input of the detection signals from both detection switches is received simultaneously, while ignoring the input of the detection switch. Stop device for electric shutters.
