PURPOSE:To discriminate a trouble etc. of a photosensor circuit, by connecting an electric power source with the one side of two terminals to connect the photosensor circuit and connecting resistance for dividing voltage and a voltage detector to the other terminal. CONSTITUTION:The titled inspecting apparatus is provided with two terminals 15, 16 to connect a photosensor circuit and a power source is connected one terminal 15 and the 2nd terminal 16 connects an A/D converter 6. In the case to discriminate a trouble of the photosensor circuit and disconnection by using such inspecting apparatus of the photosensor circuit, it is discriminated that disconnection is occurred when the converter 6 indicates 0V and the photosensor circuit 10 is faulted when the converter 6 indicates 1-1.8V. Accordingly, the discrimination of the trouble etc. of the circuit 10 is made possible by processing in this manner. |
