Disclosed herein is an X-ray image apparatus having an improved rotating unit for preventing a blind spot in which an X-ray-generating unit is not rotated from being generated. The X-ray image apparatus includes an X-ray-generating unit configured to generate X-rays and radiate the X-rays, an X-ray-detecting unit configured to detect the X-rays radiated from the X-ray-generating unit, and a rotating unit configured to rotate the X-ray-generating unit. Here, the rotating unit includes a rotating frame coupled to one side of the X-ray-generating unit； a protrusion configured to protrude from one side of the rotating unit； and a stopper being in contact with the protrusion to halt a rotation of the rotating frame and being provided such that the stopper can be moved in a preset zone. Since the stopper securing the rotating frame of the rotating unit can be moved in the preset zone, it is possible to prevent a blind spot caused by a restriction of the rotation of the rotating frame from being generated.
