X-ray photography machine with selectively coupled flanges for pressing member movement

摘要

Disclosed herein is an X-ray photography machine (300). The X-ray photography machine includes a transfer apparatus (370) which moves a pressing member (360) which presses a target. The transfer apparatus includes a drive source (371), a drive shaft (374) which is rotated by the drive force of the drive source, first and second pulleys (375a,b) which convert rotational force of the drive shaft into force by which the pressing member is moved, and first and second flanges (379a,b) which make the first pulley depend on the rotational force of the drive shaft. In the present invention, because only a single drive shaft is used to move the pressing member, problems such as the occurrence of noise can be minimized.
