X-ray photographing apparatus

The present invention relates to X-ray imaging apparatus. X-ray imaging apparatus according to the invention is an X-ray generator for irradiating a subject to be imaged; A detector for detecting the X-rays transmitted through the subject to be imaged; Pressure pad between the generator and the detector; And a moving device to move far away or close to the pressure pad from said detector; And including, the mobile apparatus, the drive shaft rotated by the motor and the rotation of the motor; The switch 1 is being rotated by the rotation of the pulley and the first pulley belt coupling said pressure pad; Clutch for selectively interlocking the rotation of the first pulley and the drive shaft by the on (on) / off (off) of the power; The to and interlocking the movement of the drive of the mobile device when on (on) of said power and said pressure pad and release the movement of the drive of the mobile device during the off (off) of the power and the pressure pad interlocking included. According to the present invention can minimize the pain or discomfort in the patient by releasing the pressure on the breast in such emergency power failure.
