PROBLEM TO BE SOLVED: To provide an X-ray radiographing apparatus which works for both CT imaging and general still-image photographing and acquires images which are effective for diagnoses without impairing operability for setting a height of an X-ray imaging part and safety. SOLUTION: An operator adjusts a position of the X-ray imaging part by operating a foot switch (S1). A control part determines whether subject supporting members such as a chair and a backrest are located at a CT imaging position by signals from a supporting member position sensor (S2). The control part permits lifting and lowering movements in accordance with the operation by the operator when the signals from an imaging part position sensor are within a range of CT imaging in a CT imaging status (S3-S6). The operator stops lifting and lowering at a desired position. When the X-ray imaging part reaches the limit position of the CT imaging range by the lifting and lowering, the X-ray imaging part is controlled to stop at the position and not to lift or lower any more (S4-S8), and the X-ray imaging part is located within the CT imaging range all the time during the CT imaging. In addition, when the subject supporting members are in the general still-image photographing status, the control part controls to enable lifting and lowering of the X-ray imaging part in accordance with the operation by the operator regardless of the result of the signal from the imaging part position sensor (S9-S10).
