RADIATION PHOTOGRAPHING APPARATUS

摘要

PROBLEM TO BE SOLVED: To make it possible to quickly change over first and second radiation detectors.SOLUTION: An electronic cassette comprises a first radiation detector 40 and second radiation detector 41. The first radiation detector 40 is configured by: a light emitting unit 33 for generating light by receiving radiation; and a first light detection unit 32 for detecting the light generated by the light emitting unit. The second radiation detector 41 comprises: the light emitting unit 33; and a second light detecting unit 34 which is arranged on the side opposite to the radiation incident side of the light emitting unit 33 and detects the light generated by the light emitting unit 33. A cassette control unit drives the first radiation detector 40 to execute still image photographing, and drives the second radiation detector 41 to execute moving image photographing. The second light detecting unit 34 has a visual field range narrower than that of the first light detecting unit 32, and is moved so as to follow movement of a radiation source.
