Abstract

A collimator comprises a pair of first plate members having X-ray absorbability and a pair of second plate members having X-ray absorbability. The pair of first plate members are movable in a direction parallel to surfaces thereof, and have respective end faces opposed to each other with an X-ray passing aperture being defined by a spacing between the opposed end faces of the first plate members. The pair of second plate members are capable of being folded in a zigzag fashion through hinges, and in order to intercept other X-rays than the X-ray passing through the aperture, each of the second plate members is connected at one end thereof to each end of the first plate members on the side opposite to the opposed end faces of the first plate members and is connected at the other end thereof to each of fixing portions.
