特徴とするシヤツターの安全装置。 A seat plate switch is installed to detect obstacles on the seat plate of the shutter curtain, which moves up and down guided by guide rails set up in the building opening, and the opening/closing drive mechanism is stopped when the seat plate switch detects the obstacle. In the safety device for a shutter, a reflective plate is installed horizontally on one side of the seat plate facing the guide rail, and a light emitter/receiver is provided at the upper end of the guide rail. A liquid crystal plate is disposed facing the optical signal transmission path formed between the plate and the light emitter/receiver, and the liquid crystal plate is configured to be switched to a shielding state in conjunction with obstacle detection by the seat plate switch.
