PROBLEM TO BE SOLVED: To reduce standby electric power of an electric shutter device for building.SOLUTION: An operation signal input device 9 which receives operation signals from a transmitter 10 and a push-button switch 23 and outputs the operation signals to an opening/closing machine 5 is provided with a power source circuit 14 for the opening/closing machine which receives and outputs electric signal from a battery 15 to the opening/closing machine 5, and power source control means 17 of controlling opening and closing of the power source circuit 14 for the opening/closing machine. The power source circuit 14 for the opening/closing machine is closed only for a set time after the operation signals are input to the operation signal input device 9 so as to supply electric power to the opening/closing machine 5, and opened at other times so as to supply no electric power to the opening/closing machine 5. A reception part provided in the operation signal input device 9 is configured to performing intermittent reception in which a receiving operation and a pause are repeated while the power source circuit 14 for the opening/closing machine is open. |
