Abstract

PURPOSE:To eliminate any member interfering with the view field of an operator when the X-ray diagnostic device concerned is moved toward a patient to be inspected and reduce the weight of an elevating/sinking mechanism of an X-ray tube supporting part by equipping the spring balance function which exerts weight balancing for an X-ray source holding part. CONSTITUTION:Weight of an X-ray tube holding part 23 applied to an expanding/contracting pillar 22 is conducted to a cone pulley 28 via a rack 26 and pinion 27 installed to a component member 22b and balanced with the resilient force of a spring 29 in connection with a wire W wound into the pulley 28. Change in the weights of the pillar 22 and X-ray tube holding part 23 in the position where the pillar makes expansion/contraction can be compensated. The operator sinks the X-ray tube holding part 23 to a level which does not obstruct his own view field at least, and in this condition, this X-ray diagnostic device concerned is moved toward the patient. There is no fear that any obstacle remains within the view field of the operator, so that traveling between the patient and the device accommodation place can be done smoothly.
