Summary:PURPOSE:To prevent the erroneous detection of resonance immediately after a power source is inputted by outputting the information on the occurrence of resonance when the temperature of a rubidium resonance means amounts to a prescribed temperature. CONSTITUTION:The temperature of a rubidium resonance means 113 is controlled by a temperature control means 115, and the resonance of the rubidium is caused by transitional frequencies synthesized by a frequency synthesizing means 121 from the output of a crystal oscillator 111. When the temperature of the rubidium resonance means 113 amounts to the prescribed temperature, a connecting means 119 produces the output of the rubidium resonance means 113 to a frequency control means 120 and a resonance detecting means 117. Based on the output, the resonance detecting means 117 detects the generation of the resonance, and the frequency control means 120 controls the crystal oscillator 111. Thus, when the temperature of the rubidium resonance means 113 attains to the prescribed temperature, the information concerning the resonance is outputted, and the erroneous detection of the resonance immediately after the power source input can be prevented.
