Abstract: 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 (375 a,b) which convert rotational force of the drive shaft into force by which the pressing member is moved, and first and second flanges (379 a,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.

Abstract: The present invention relates to a photographing device including a power transmission unit. The power transmission unit includes a frame unit which is connected to the second drive body, an adaptor unit which is connected to the frame unit and is selectively connected to the first drive body or the support body by external power, an actuating unit which operates the adaptor unit, and a power unit which transmits power to the actuating unit. According to the power transmission unit of the X-ray mammography device, since biopsy photography and tomography can be performed using only one power transmission unit, the weight and size of the rotating arm may be reduced, and the vibration and noise produced thereby may be reduced. Thanks to the simple operation mechanism of the power transmission unit, power loss may be reduced, and the durability of each component may be improved.

Abstract: The present invention relates to an X-ray imaging apparatus comprising an X-ray source unit generating an X-ray, an X-ray detecting sensor unit having a sensor panel equipped with multiple sensors detecting the X-ray which is generated from the X-ray source unit and passed through an object, and a panel-moving means mounted on the X-ray detecting sensor unit and moving the sensor panel. Thus, employing and butting multiple small X-ray sensors instead of expensive large sensors advantageously reduces the manufacturing cost for the X-ray imaging apparatus, and enables the imaging of the same wide area as with the use of the large sensors.
