Radiographic image capturing apparatus and radiographic image capturing system

A radiographic image capturing apparatus comprising:

• a radiation source device including a radiation source for outputting radiation;
• and
• a detector device including a radiation detector for detecting radiation that is transmitted through a subject when the subject is irradiated with radiation by the radiation source, and converting the detected radiation into a radiographic image;
• at least one of the radiation source device and the detector device having an electric power supply limiting unit for limiting supply of electric power;
• the electric power supply limiting unit comprising:
• an activator/deactivator for determining activation or deactivation of supply of electric power between the radiation source device and the detector device, based on a present position of a corresponding one of the radiation source device and the detector device, or based on a distance between the radiation source device and the detector device;
• and
• an electric power supply activator for enabling supply of electric power between the radiation source device and the detector device, if the activator/deactivator determines activation of supply of electric power between the radiation source device and the detector device.
