The present invention relates to an X-ray imaging apparatus. In the X-ray imaging apparatus according to the present invention, the moving device that moves the compression member that compresses the object to be imaged includes the driving source, the driving shaft that rotates by the driving force of the driving source, and the rotational force of the driving shaft as the moving force of the pressing member. The first and second pulleys to be transmitted and the switching belt, and first and second flanges for binding the first pulley to the rotational force of the drive shaft are included. According to the present invention, since the compression member is moved by one drive shaft, there is an effect that problems such as abnormal noise are minimized.本発明は、Ｘ線撮影装置に関する。本発明に係るＸ線撮影装置において、撮影対象を圧迫する圧迫部材を移動させる移動装置は、駆動源、駆動源の駆動力により回転する駆動軸、駆動軸の回転力を圧迫部材の移動力として伝達する第１、第２プーリと切替ベルト、第１プーリを駆動軸の回転力に束縛させる第１及び第２フランジを含む。本発明によれば、１つの駆動軸で圧迫部材を移動させるため、異常騒音などの問題を最小化させるとの効果がある。
