Claims

[Scope of utility model registration request]

A shutter safety stop device in which a photoelectric sensing mechanism that optically detects the presence or absence of an obstacle at a lower position of the shutter seat plate is coupled to a lowering control mechanism that controls the lowering operation of the shutter opener. A photoelectric sensor installed on the case side that emits and receives light, and a reflector that forms multiple optical paths below the seat plate to receive the light beam emitted from the photoelectric sensor by the photoelectric sensor. A safety stop device for a shutter, comprising: a device for stopping the lowering operation of the shutter in conjunction with blocking a portion of the plurality of optical paths;
