Abstract
Provided is a mobile X-ray apparatus that is capable of safely charging multiple mobile X-ray apparatuses. A power supply deviceincludes a plugan electrical outleta batterya control unita current detectorand a power supply circuitThe power supply circuitincludes a power limiting circuitan external output circuitand a charging circuitThe power limiting circuitlimits power together with the control unitIn the power supply circuiti) if an external output circuitside is current-limited, charging is preferentially performed, and ii) if the charging circuitside is current-limited, power is output preferentially to external equipment. In the power supply circuitthe current of one current path is limited, and a large amount of current is allowed to flow preferentially in the other current path.
