Radiographic image capturing apparatus

A radiographic image capturing apparatus comprising:

• a two-dimensional array of radiation detecting elements;
• a connector couplable to an external connector;
• a connector coupling detector to detect coupling or uncoupling between the external connector and the connector of the radiographic image capturing apparatus;
• a power supply detector to detect an available state or an unavailable state of external electric power fed through the external connector;
• and
• a controller to control a turned-on state and a turned-off state of the radiographic image capturing apparatus, wherein
• at a timing when the power supply detector detects a change from the available state to the unavailable state of the external electric power, the controller turns off the radiographic image capturing apparatus in the turned-on state if the connector coupling detector detects the coupling between the external connector and the connector of the radiographic image capturing apparatus, or the controller maintains the turned-on state of the radiographic image capturing apparatus if the connector coupling detector detects the uncoupling between the external connector and the connector of the radiographic image capturing apparatus.
