PROBLEM TO BE SOLVED: To provide the constitution for normally performing radiographing operation even if an image data transfer line becomes noncommunicable by failure because of increasing in cases of properly using kinds of connecting cables in such a state of using an optical fiber for transferring image data, and a metal cable for controlling the radiographing timing, and supplying a power source for an interface between a sensor unit and a control part, and because of having defects such as being easily collapsible to bending in a structure, and deteriorating a transmission characteristic due to an increase in a loss while here are many in advantages such as high speed, large capacity, a thin diameter, and lightness in the optical fiber. SOLUTION: A means is arranged for detecting abnormality of a transfer route of image data transferred to the control part from the sensor unit. A means is arranged for automatically switching the image data transfer route when detecting the abnormality. The image data transfer route can be self- diagnosed by using mutually different image data transfer route by an automatic switching means.
