機構。 A driving screw is provided at one end of the fulcrum of the support arm, and a balance weight is provided at the other end, and an imaging device is connected to the driving screw via a nut, and by rotating the driving screw forward and backward, the imaging device is directed toward the subject. In the proximity/retraction movement drive device for an X-ray fluoroscopic imaging table, the apparatus is configured to move the imaging device toward and away from the patient and to detect the compressive force generated when the imaging device comes into contact with a subject by the displacement of the supporting arm. An approach/retreat drive mechanism for an X-ray fluoroscopic imaging table, characterized in that a movable weight movable in a direction intersecting a support arm is provided.
