Claims

[Scope of Claim for Utility Model Registration] A heating device having a signal generator that generates a heating start signal for a getter disposed in a cathode ray tube, a flash time measurement timer that measures the time from the start of heating of this device until the getter flashes, and this It is characterized by comprising a flash time judgment timer that compares the measured value of the measurement timer with a predetermined setting value and an optical sensor that detects flash light including a flash start time recorder, and measures and controls the getter flash start time. Getta flash control device.
