Radiographic imaging system, radiographic imaging apparatus, battery charger, and method of inspecting waterproof performance

A radiographic imaging apparatus including a casing that houses a radiation detecting element that detects radiation with which a subject is irradiated and a battery, the casing being provided with a vent hole that circulates internal and external air, and the radiographic imaging apparatus comprising:

• an air pressure measurer that measures an internal air pressure of the casing;
• a hardware processor that inspects, after the internal air pressure of the casing changes due to operation of pressure, waterproof performance of the radiographic imaging apparatus based on a changing aspect of the internal air pressure due to termination of the operation of the pressure, and
• a flow rate regulator that reduces a flow rate of the air through the vent hole in a case where the battery is charged.

A battery charger provided in a radiographic imaging apparatus including a casing that houses a radiation detecting element that detects radiation with which a subject is irradiated and a battery, the casing being provided with a vent hole that circulates internal and external air, the battery charger charging the battery, and the battery charger comprising:

• a holder that holds the casing of the radiographic imaging apparatus;
• and
• a flow rate regulator that reduces a flow rate of the air through the vent hole in a state where the casing is held.
