Abstract

PURPOSE:To achieve the automation of warm-up by providing a warm-up circuit capable of enabling voltage during an initial period to rise continuously and making a control signal, the rising rate of which is decreasing during the initial and last period of warming up. CONSTITUTION:By switching a warm-up switch 21 to A position, charging a capacitor 30 and adjusting a resistor 14, a tube is set up at the maximum voltage. By switching the switch 21 to B position, an output corresponding to the minimum tube voltage is output from a comparator 12 and decreases to a voltage of the capacitor 30 by discharging. Referring to discharging curves (a) and (b), a transistor 31 gets rid of a saturation state and an output of the comparator commenses to rise gradually at time T1. At T2, a transistor 31 becomes to be in off-state and yields the output corresponding to the maximum tube voltage. After keeping this voltage for a while, the output of the comparator inverts and the warm-up is achieved.
