An electronic cassette has a detection panel (light detection substrate) in which pixels for accumulating electric charges corresponding to radiation are arranged. The electronic cassette includes two gate control circuits that control an operation of a gate drive circuit, a power supply circuit that supplies power to the gate control circuits, a first wiring line, and a second wiring line. The first wiring line connects the power supply circuit and each of two gate control circuits to each other, and supplies each of two gate control circuits with the power supplied from the power supply circuit. The second wiring line connects two gate control circuits to each other. The power supplied from the power supply circuit to one of two gate control circuits is diverted to the other, through the second wiring line.

A radiographic capturing apparatus includes the following. A wireless communication circuit or a wireless communication device establishes wireless communication with an external unit. A power supply circuit feeds electrical power to the wireless communication circuit or the wireless communication device and is switchable between a low-load mode and a high-load mode.

An electronic cassette is provided with a sensor panel, a housing, operation buttons, a head-bottom setting section, lamps and a memory. The sensor panel has a quadrangle imaging area, and detects an X-ray image of a patient. The housing houses the sensor panel. The operation buttons are disposed on the housing. When either one of the operation buttons is pushed down, the head-bottom setting section sets either one of adjoining two sides of the imaging area to be the head of the radiographic image in the display orientation. The display section is disposed on the housing, and displays which side is set by the head-bottom setting section to be the head of the radiographic image. The memory stores head-bottom setting information and the radiographic image in association with each other.
