Title:
RADIATION THICKNESS MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2023043296
Kind Code:
A
Abstract:
To provide a radiation thickness measuring device capable of reducing heat generation of a rotary solenoid.SOLUTION: A radiation thickness measuring device in one embodiment comprises a radiation generation part, an arm, a rotary solenoid, and an electro magnet. The arm can be attracted by magnetic force at least partially, and is rotatable around a rotary shaft. The rotary solenoid is excited for rotating the arm from a first position being one of a closed position where the arm is arranged on a path of a radiation emitted from the radiation generation part and an open position where the arm is separated from the path of the radiation, to a second position being the other of the open position and the closed position, around the rotary shaft. The electro magnet is excited for attracting the arm positioned at the second position by the magnetic force, and holds the arm at the second position.SELECTED DRAWING: Figure 2
