Abstract: PURPOSE:To shorten a preliminary overheating time by detecting a difference between an actual value and a target value of a filament temperature suitable for obtaining a desired tube current, and performing over-drive at a frequency according to a magnitude of a difference signal during a preliminary heating period of the filament temperature. CONSTITUTION:When a detection voltage Vd is lower than a set value of an undervoltage setter 21 at the time of pre-heating start, a comparator 22 determines an undervoltage to output an undervoltage signal S1 of an H level. A set signal S2 of a flip-flop 25 is output at a time t1 on the basis of an AND condition between the signal S1 and a signal S6 of an H level applied from an on-delay timer 28 to an AND gate 24. When the flip-flop 25 is latched by the signal S2 and a signal S3 of an H level is output to the output side thereof, a (b) contact of an analog switch 29 is closed and an over-drive signal is added from a signal source 30 to the input side of a current regulator 13.
