<p><P>PROBLEM TO BE SOLVED: To provide a grid attachment and removal mechanism in a radiation image information recording apparatus which reduces the burden on a worker by facilitating a replacement work of a grid and avoids damage on the grid or a device for loading the grid due to the falling of the grid during the grid attachment and removal. <P>SOLUTION: A constant load spring member 50 is placed in a grid accommodating part 42. The member 50 has a shaft 52 rotatably supported by a bearing in an upper part of the grid accommodating part 42. Drums 54 are firmly fixed to both ends of the shaft 52, and plate-shaped members 56 made of a stainless steel strip for springs or the like are wound around the drums 54. The plate-shaped member 56 is fixed to the drum 54 at one end, and is wound around the drum 54 tightly at a certain curvature. <P>COPYRIGHT: (C)2004,JPO</p> |
