RADIOGRAPHY APPARATUS, COLLISION DETECTOR, AND BUFFER

摘要

PROBLEM TO BE SOLVED: To realize a radiography apparatus equipped with a collision detector of a simple structure, a collision detector of a simple structure, and a buffer for the collision detector. SOLUTION: The buffer (210) is a hollow body with a fluid enclosed inside. A side of the buffer on which an object (204) to be mounted abuts is formed into a recessed part fitting the shape of a corner part of the object to be mounted, and the other side is formed into a protruded part conforming to the shape of the corner part of the object to be mounted. The hollow body forms a ring conforming to the edge of the object to be mounted. The ring is an annulus. An internal pressure of the buffer is detected by a detecting means, which is notified whether a collision with an obstruction occurs. COPYRIGHT: (C)2005,JPO&NCIPI
