Abstract: An X-ray radiation device comprises a plurality of X-ray radiation units, each having an X-ray tube for generating an X-ray, a drive circuit for driving the X-ray tube, and a trunk line connected to the drive circuit, and a controller having a control circuit for controlling the X-ray radiation units. The trunk lines of the plurality of X-ray radiation units are connected in series to the control circuit so that the drive circuits of the plurality of X-ray radiation units are connected in parallel to the control circuit. Since the trunk lines of the plurality of X-ray radiation units are connected in series to the control circuit, the X-ray radiation units can be connected to each other and are not required to be connected one by one to the controller. This makes it possible to increase and decrease the number of units without complicating their wiring.

Abstract: In an X-ray radiation source, a lid part is fastened to a main part with screws, so that an X-ray tube is secured to a housing while being pressed against an inner surface of the wall part a by a first circuit board. The X-ray tube can be secured stably within the housing by thus being held between the first circuit board and the wall part. The X-ray radiation source uses the first circuit board incorporated in the housing itself for pressing the X-ray tube. This makes it unnecessary to provide new members for pressing the X-ray tube and can prevent the device structure from becoming complicated.
