PROBLEM TO BE SOLVED: To prevent the increase of a noise level caused due to the overlapping of higher harmonic wave noises caused by each block signal to transmit the control signal and image signal. SOLUTION: The image signal is obtained by detecting X-ray transmitted through examinee by X-ray detector at the rotating part 1. The control signal controls the circuit operation of the rotating part 1. The frequency of the clock signal to transmit the image signal from the rotating part 1 to the fixed part 2 through the transmitting path 3, and the frequency of the clock signal to transmit the control signal from the fixed part 2 to the rotating part 1 through the transmitting path 4, are set to different frequency. The increase of noise level caused by overlapping of high harmonics originating from each clock signal at the same frequency, is simply prevented by this procedure.
