A radiation imaging apparatus that captures radiographic images includes a radioactive ray generating unit configured to irradiate a subject with a plurality of radioactive rays generated by a plurality of electron sources. The ability to use a 90 degree elbow style cable connector allows the EEV footprint to be minimized which provides an advantage when the electric expansion valve is installed in the tight confines of a package system. The rotatable reflector support system comprises an elongated reflector having first and second longitudinal ends. Furthermore, the adjustment circuit outputs the number of voice packets that have dropped out, the number of substitute packets that have been inserted, and the number of voice packets that have accumulated inside the circuit, as quality information in each monitoring period. At the trailing end face directed away from the setting direction of the bolt, the bolt has at least one peripheral recess with a depth providing a setting control and that can be economically manufactured. The force is preferably either perpendicular to the optical axis, or generally perpendicular wherein the zonular plexus is deflected inwardly approximately along an axis bisecting the angle described by the anterior zonular fibers when viewed in a horizontal plane.
