Abstract

PURPOSE:To obtain a correct control of the intensity for a tube, by feeding a charging voltage of the charging circuit, charged to a voltage corresponding to a voltage of the tube for a preset exposure condition, to the X-ray tube through tetrodes and controlling the tetrode with a signal of an image amplifying tube. CONSTITUTION:When an exposure condition is determined, a setter tube voltage control circuit 44 compares a voltage of a bleeder resistance 43 with a reference value to control a voltage of a charging circuit 33 in such a manner as to obtain the preset value, permitting the generation of a high voltage from a high voltage generator 31. This high voltage output is rectified by a rectifier circuit 32, stored in the charging circuit and applied to tetrodes 34a, 34b. A correction signal generator circuit 39, to which a photographing signal from a cinecamera is input, detects a quantity of light detected at each time of photographing if more or less as compared with a prescribed value and feeds a control quantity of the correction to a grid control circuit 40. Then correction outputs from this circuit are fed to grid voltage regulating circuits 41a, 41b and used as a signal for controlling the tetrode.
