Abstract
PURPOSE:To improve the gain of the frequency to raise the Q value by reducing the displacement of the mount part and leakage of oscillation by supporting a combined tuning fork type quartz oscillator by two leads. CONSTITUTION:A combined tuning fork quartz oscillator 10 is supported a proper distance apart from a plug 13 by leads 11. Since frequencies of bending oscillation and torsional oscillation are changed by changing the distance and the length of leads, an optimum value is selected as a parameter in respect to the length S. Then, a region where coupling between leads 11 and the resonator 10 is weak is obtained. At this time, since oscillation of the plug 13 can be reduced in the relation between the plug 13 and leads 11, the fluctuation of the frequency is reduced even if the equivalent mass of the plug 13 is changed. Leads 11 are folded to hang the oscillator 10, and otherwise, they are linear a proper distance apart from the plug 13.
