Title: MOVING-TYPE RADIATION DEVICE
Abstract:
The present invention provides a highly safe moving-type radiation device. In conventional configurations that use tension springs, if a spring is severed, the fragments will separate permanently. Thus, the present invention uses compression springs 8a, 8b instead. In the spring structure of the present invention, even if a spring is severed and a shaft goes to make a large-scale movement, the fragments of the spring, which will catch on each other and be immobilized, will interfere and prevent the movement. What has been devised for the present invention is an intermediary spring seat that links a plurality of compression springs 8a, 8b. Because of the intermediary spring seat, the compression springs 8a, 8b will not buckle even if the compression springs 8a, 8b are linked in series.
