Abstract: PURPOSE:To accurately and surely inform the vacant position of each parking lot at present by detecting a parking state and the fault of a device without being affected by external environment by modulated light on the bottom part of a vehicle and reflected light from a reflection part. CONSTITUTION:When the vehicle is parked, intensity of light can be increased since both the reflected light 6-1, 6-2 from a light source 4 are made incident, and both output OUT1, 2 are set at H. Meanwhile, when no vehicle is parked, no reflected light 6-1 is made incident on a light receiving part 7, and only the reflected light 6-2 with the surface reflection of transparent glass 3 is made incident. An incident signal Wo is adjusted in advance so that it can exist in a level less than a reference signal (a) and over a reference signal (b) by adjusting the values of the signals Wo, (a), and (b). Therefore, the output OUT1 goes to L, and the output OUT2 to H when no vechicle is parked. Furthermore, when the fault occurs in the light source 4, the reflected light 6-1, 6-2 disappear, and the light reception signal Wo goes less than the signals (a), (b), and both outputs OUT1, 2 go to L.
