Abstract

PURPOSE: To obtain a prescribed thickness constantly at a beam center even when the position of stoppage of the reference plate is slipped by fitting the reference plate to an arm so as for the direction of processing of the reference plane thereof to accord with the direction of action thereof.
CONSTITUTION: The base end part of the arm 6 is fitted to a rotary solenoid 5 and further the reference plate 7 having a prescribed thickness is fitted to the tip of the arm 6 so as for the direction of processing of the reference plane of the reference plate to accord with the direction of action, i.e. the direction of rotation thereof. Since the reference plate is fitted to the arm 6 so as for the direction of processing wherein the variation of thickness of the reference plane 7a is little to accord with the direction action in this way, the prescribed thickness can be obtained constantly even when the position of stoppage of the reference plate is slipped by exciting the rotary solenoid 5 to rotate the arm 6 and thereby positioning the reference plate 7 at the beam center 9 of radioactive rays 8.
