PROBLEM TO BE SOLVED: To provide a radiography system which removes the defects of conventional technology, can confirm the angle information on both tilt angles from one operation position, and can lessen the burden of an operator. SOLUTION: The X-ray head 4; 16; 76, the more than one head angle sensor 58, 60; 78, 80, and the display means 64; 94 are provided in the system. Each of the head angle sensor 58, 60; 78, 80 provides an output signal to show a measured angle. The display means 64; 94 shows an image of the angle information on each of the head angle sensor 58, 60; 78, 80 in response to this output signal and is arranged in a single visible station.
