Abstract

PURPOSE: To miniaturize a rotary shutter for separate exposure and to use X-rays with high efficiency by driving a shutter plate, arranged in an airtight container, externally by use of electromagnetic force.
CONSTITUTION: Rotary cyclinder 8 provided at one end surface with shutter plate 1 having notch window 3 is sequentially rotated for separate exposure. Permanent magnets 4a and 4b provided on the outer circumference of rotary cylinder 8 have magnetic poles opposing to each other along the circumference and rotary cylinder 8 is supported in vacuum contaniner 2 by steel balls 9 being horizontally rotatable. Cohering to the outer circumference of vacuum container 2, four electromagnets consisting of yoke 5 and coil 6 are arranged at quartered points of the circumference and each yoke 5 is coupled by magnetic-substance ring 7. Then while the polarity of each electromagnet is controlled in accordance with the direction of electric current flowed through coil 6, rotary cylinder 8 is intermittently turned in vaccum container 2 by external driving through magnetic force action between permanent magnets 4a and 4b and those electromagnets.
