PROBLEM TO BE SOLVED: To provide a voltage system for driving a light or radiation detector, capable of accurately reading out electric charge information, even if the size of a power part is increased. SOLUTION: Cables 15, 25 for electrically connecting a power part and a radiation detector 30 are employed to separate each function of the power part and the detector 30. Even if the size of the power part is increased, the power part can be mounted in a desired position, by adjusting the length of the cables 15, 25. A sensing part 20 is provided to control voltage to a predetermined level in the event that the cables 15, 25 suffer from noise inclusion/generation or voltage drop. By providing the cable 15 between the power part 10 and the sensing part 20 for electrically connecting them, and the cable 25 between the sensing part 20 and the detector 30 for electrically connecting them, the sensing part 20 can supply voltage controlled at a predetermined level, and electric charge information can be read out accurately. Accordingly, even if the size of the power part is increased, the electric charge information can be accurately read out. COPYRIGHT: (C)2005,JPO&NCIPI
