A terminal resistor apparatus includes an input-side switch, an input-side terminal resistor, an output-side switch, and an output-side terminal resistor. When a plurality of the terminal resistor apparatus are connected, the input-side switch of the first terminal resistor apparatus will be conducted so that the input-side terminal resistor will be connected, but the output-side switch will not be conducted so that the output-side terminal resistor will not be connected. The input-side switch of the last terminal resistor apparatus will not be conducted so that the input-side terminal resistor will not be connected, but the output-side switch will be conducted so that the output-side terminal resistor will be connected. The input-side switches of the other terminal resistor apparatus will not be conducted so that the input-side terminal resistors will not be connected, and the output-side switches will not be conducted so that the output-side terminal resistors will not be connected.
