ABSTRACT:
A state detection device is disclosed that is for detecting driving states of plural loads which are connected with each other in parallel and are driven by a driving unit. The state detection device includes a voltage detection unit for detecting voltages applied to the loads; a combined voltage generation unit for generating a combined voltage equivalent to a combination of the detected voltages; and a state detection unit for detecting driving states of the loads based on a magnitude of the combined voltage and magnitudes of the voltages applied to the loads.
