An X-ray generation device is provided with an X-ray generation tube having a cathode including an electron emission unit that emits electrons in a first direction and an anode including a target that generates X-rays by colliding with the electrons emitted from the electron emission unit, a voltage supply unit, a storage container, and an insulating member. The voltage supply unit supplies a voltage to the X-ray generation tube via a conductive wire, and the storage container has a first portion forming a first space for storing the voltage supply unit, a second portion forming a second space for storing the X-ray generation tube, and a connecting portion connecting the first portion and the second portion to the X-ray generation tube. And a connecting portion that connects the first portion and the second portion to each other so as to form an internal space in which the first space and the second space communicate with each other, the connecting portion having a protruding portion that is tapered toward the internal space, and that has a width in a first direction that is perpendicular to the first direction that is smaller than that in a second direction that is perpendicular to the first direction that is smaller than that in the first space. The insulating member is disposed in the internal space so as to surround at least a portion of at least one of the conductive wire and the cathode. The insulating member is disposed so as to block at least the shortest path between the conductive wire and the protruding portion, and is disposed so as to have a structure in which at least two members are bonded by means of an adhesive material. A linear path between the adhesive material and the conductive line and a linear path between the adhesive material and the cathode are blocked.
Description
technical field [0001] The present invention relates to an X-ray generator and an X-ray imaging device. Background technique [0002] The closer the distance between the X-ray generating portion formed on the target (Japanese: ターゲット) and the subject is, the more likely the magnification of the X-ray transmission image will increase. Then, there is known an X-ray generator in which a protruding portion protruding elongatedly from the main body of the storage container is provided in order to obtain sufficient magnification even when the subject is located on the far side. , an X-ray generator is installed at the end of the protruding part. Such an X-ray generator is described in Patent Document 1. [0003] Patent Document 1 describes an X-ray generator including an X-ray generator tube and a storage container for storing the X-ray generator tube. The X-ray generating tube includes: an anode; a cathode having an electron emission source; and an insulating tube forming a vac...
