Abstract
In an X-ray apparatus, an X-ray film is placed in an closed space formed by front and rear sensitizer screen supports and a closing member fixed to one of the sensitizer screen supports so that a part of the X-ray film projects outside the closed space. The closed space is evacuated so that the sensitizer screens are brought into close contact with opposite sides of the X-ray film under vacuum. The front and rear sensitizer screen supports are movable between the X-raying position and a retracted position shifted from the X-raying position and are movable relative to each other in the retracted position between a closing position where the supports form the closed space together with the closing member and an open position where the supports form therebetween a wedge-shaped space flaring upward to permit insertion and removal of the X-ray film into and from the space. A transfer rollers hold the part of the X-ray film projected outside the closed space and insert and remove the X-ray film into and from the wedge-shaped space from above when the sensitizer screen supports are in the open position. Evacuation of the closed space is started as soon as the sensitizer screen supports are moved to the closing position in the retracted position.
