ABSTRACT:
A pull-down resistor is connected to a power source line between power source connectors and a detector circuit in an apparatus in which a power source is connected via the power source connectors to the detector circuit, which includes a temperature-sensitive resistor and which outputs a voltage signal to a control unit via signal connectors. The pull-down resistor increases current flow to the power source connectors thus to suppress oxide formation thereon. A pull-up resistor or a pull-down resistor is connected to a signal line between the signal connectors and a filter circuit in the control unit, in order to increase an electric current that flows into the signal connector terminals thereby to prevent the formation of an oxide film on the signal connector terminals.
