The present invention discloses a mobile X-ray machine device, which comprises an X-ray source module, a body portion, a base, a control module and a transmission arm module. The base has a lifting unit. The transmission arm module is disposed on the base, connected between the X light source module and the base, and includes a first arm and a second arm, wherein one end of the first arm is connected to the lifting unit of the base The other end of the first arm is pivotally connected to one end of the second arm to form a first rotating shaft, and the other end of the second arm is connected to the X light source module, wherein the control module is electrically connected to the transmission arm module, The lifting unit controls the height of the transmission arm module, and controls the second arm to rotate with the first rotating shaft as an axis, so that the X light source module is displaced to a specific position.本創作係揭露一種移動式X光機裝置，其結構包括X光源模組、本體部、基座、控制模組以及傳動臂模組。基座具有一昇降單元。傳動臂模組設置於基座上，連接於X光源模組與基座之間，且包括一第一支臂以及一第二支臂，其中第一支臂的一端連接至基座之昇降單元，第一支臂的另一端與第二支臂的一端樞接形成一第一轉軸，第二支臂的另一端連接至X光源模組，其中控制模組電連接至傳動臂模組，以昇降單元控制傳動臂模組之高度，且控制第二支臂以第一轉軸為軸心轉動，俾使X光源模組位移至一特定位置。
