Claims

[Scope of utility model registration request]

A detection switch installed on the seat plate of a shutter curtain that opens and closes along a guide rail to detect obstacles; a transmitter that receives a detection signal from the switch and outputs an infrared signal; and a transmitter that outputs an infrared signal through a light receiving window. In the electric shutter, the electric shutter is equipped with a receiver configured to receive signals from The control device is configured to output an infrared signal corresponding to the binary code, and the control device is configured to respond only when the binary code of the signal received via the receiver matches the preset binary code, An electric shutter device characterized in that the receiver is formed by applying a mesh-like conductive shield to the light receiving window.
