PROBLEM TO BE SOLVED: To provide a safety lamp for power failure which is high in facility by emitting the light to the periphery of an apparatus main body by lighting a safety light source by a power failure sensor housed in the apparatus main body at power failure time. SOLUTION: When power failure by an accident or the like is caused in a condition where a safety lamp part 26 is installed in an apparatus main body 22, a power failure detecting device 40 detects power failure, and electrically connects a battery 29 and a safety light source 27 with each other in the power failure detecting device 40, and lights the safety light source 27. When the safety lamp part 26 is separated from the apparatus main body 22 in this condition, a connector 29 separates from a connector 30, and a switch 32 is closed, and an open circuit of the battery 29 and the safety light source 27 is constituted in the safety lamp part 26, and the safety light source 27 is continuously lighted, and the safety light source 27 can be optionally flashed by a manual switch 31. Even if a switch 32 is opened, when it is installed in the apparatus main body 22, it is reset in a closed condition by a projection 34. The safety light source 27 is exposed onto the apparatus main body 22 through a light diffusive-light transmissive cover, and since the light is emitted to the periphery of the main body 22, the safety lamp part 26 can be confirmed from everywhere in a room. |
