Abstract: An electronic cassette comprises a main battery which is detachably attached to a battery loading unit, and a sub-battery which supplies electricity to a bias power circuit and so on in substitution for the main battery. A power source selector changes the power source to the sub-battery from the main battery when it is judged that a replacement operation of the main battery is started.

Therefore, a start-up time TR2 is largely shortened from a start-up time TR1.
