PROBLEM TO BE SOLVED: To provide fluoroscopic photographing apparatus capable of continuing X-ray irradiation in the accurate timing in a stable state in the X-ray irradiation and X-ray irradiation stopping even when performing X-ray photographing while performing reciprocating operation of plural times. SOLUTION: A control means 63a sets an X-ray irradiation starting angleθ1 and an X-ray irradiation finish angleθ2 to an X-ray irradiation starting angle setting part 63b and an X-ray irradiation finish angle setting part 63c by receiving information on the X-ray irradiation starting angleθ1, the X-ray irradiation finish angleθ2 and a reciprocating frequency of a support arm for continuously performing radiography when the radiographing is indicated from an operation part 61. Next, angle output from a position sensor 27a is monitored, and after confirming that the angle output becomes the X-ray irradiation starting angleθ1, a temporary permission signal is outputted to a temporary permission signal generating part 63d, and after counting a frequency becoming the X-ray irradiation starting angleθ1 on the angle output from the position sensor 27a on the basis of a frequency of reciprocating motion indicated from the operation part 61, output of the temporary permission signal is released.
