When the pulse light of (e) is irradiated, the light receiving signal of the reflected light (f) by the tile or the like is output from the light receiving unit 8. However, the operation analyzing unit II9 judges that there is no change in the light receiving signal and determines that it is unmanned. The bather and the movement of the bather are analyzed using the signal as an initial value. Next, when the bather goes up to the washing room, it becomes a light receiving signal (g), which is compared with (f) in the motion analysis unit II9, and the bather makes a judgment and according to the bather's movement when he / she is washing his body in the washing room. The light receiving signal is (g) → (h)
There is no problem if the change ± △ v when changing to (i) is larger than the preset reference value, but if the bather falls down and ± 倒 v is lower than the set reference value, the limited time If it exceeds, an alarm signal is output from the alarm output unit 3 and an externally connected automatic alarm is activated, and a sound and light are sent to a family, a nurse, or a nursing center or a fire department via a telephone line.
