To automate positioning operation of an X-ray tube so as to reduce the inspection time. Anatomical program selection means selects a surgery method/imaging object portion so that an imaging condition stored as an anatomical program in advance is called out and set in an X-ray generation device. Here, when an operation switch is pressed, control means moves drive means built in X-ray irradiation means parallel movement holding means and X-ray irradiation means rotation holding means so as to obtain the positional relationship between an X-ray tube and an FPD stored in correspondence with the anatomical program (such as SID and incident angle). The position of the FPD should be matched with the examinee. However, since the positional relationship between the X-ray tube and the FPD is almost constant in accordance with the surgery method/imaging object portion, it is possible to reduce the time required for positioning the X-ray tube by using this configuration.
