X-RAY PHOTOGRAPHY MACHINE

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.

主权项

1. An X-ray photography machine, comprising:
a generator emitting an X-ray onto a target; a detector sensing the X-ray that has penetrated the target; a pressing member disposed between the generator and the detector; and a transfer apparatus moving the pressing member towards or away from the detector, wherein the transfer apparatus includes a drive source for providing a rotational force;
a drive shaft rotated by the rotational force;a first flange fitted on the drive shaft;a second flange provided around the drive shaft with a space defined therebetween, the second flange being selectively coupled to the first flange; anda switch belt connected to the second flange, with the pressing member fastened to the switch belt.
