PROBLEM TO BE SOLVED: To provide radiographic equipment for doctor's round visits which permits noise of the equipment to be restrained by rotating the anode of an X-ray tube at low speeds by operating it in a silence mode when the silentness of the equipment is required. SOLUTION: The radiographic equipment for doctor's round visits includes a traveling cart 1, the X-ray tube supporting portion attached to the traveling cart, an anode rotating X-ray tube 3 supported by the X-ray tube supporting portion, an anode driving control portion 8 supplying a voltage to the anode rotating mechanism of the X-ray tube and controlling the rotation of the anode, a high-voltage generator 9 mounted on the traveling cart and applying a high voltage to the X-ray tube, and an X-ray detector provided on the traveling cart and detecting an X-ray transmission image from a subject. The anode driving control portion can change the rotating speed of the anode 4 of the X-ray tube during X-ray irradiation, and operates the anode of the X-ray tube in the silence mode in which it rotates at low speeds when it is judged that a silent operation is required on the basis of preset radiographic conditions or when a silent action command is input.
