Patent ID: 8346115

Claim:
A power supply circuit identification device for identifying a type of a power supply circuit that supplies electrical power to an electrical load, the power supply circuit having an input terminal to which a control signal for controlling the electrical power supplied to the electrical load is input and an output terminal from which a detection signal is output, wherein the detection signal indicates whether the electrical power corresponding to the control signal input from the input terminal is supplied to the electrical load, at least one of the input terminal and the output terminal being plurally provided and having a type-dependent correlation between the input and output terminals, the power supply circuit identification device configured to function as: a control section configured to input the control signal to the power supply circuit via the input terminal; a reading section configured to read the detection signal from the output terminal; and an identification section configured to identify the type of the power supply circuit based on a reading result from the reading section, wherein the control signal input from the control section to the power supply circuit via the input terminal is an activation level signal configured to start power supply from the power supply circuit to the electrical load.
