Patent ID: 8305674

Claim:
A method of manufacturing an oscillator device having a plurality of oscillators supported relative to a fixed member by a plurality of torsion springs for oscillation around a torsion axis and arranged to be driven at respective resonance frequencies, said method comprising: a first step for determining assumed values of respective inertia moment weights of the oscillators; a second step for measuring the resonance frequencies; a third step for calculating respective spring constants of the torsion springs, from the assumed values of the inertia moment weights and the measured resonance frequencies obtained at said first and second steps; a fourth step for calculating an adjustment amount for the inertia moment weights corresponding to the plurality of oscillators or for the spring constants corresponding to the plurality of torsion springs, based on the spring constants calculated at said third step and target resonance frequencies determined with respect to the resonance frequencies of the plurality of oscillators, so as to adjust the resonance frequencies to the target resonance frequencies; and a fifth step for adjusting the resonance frequencies of the plurality of oscillators to the target resonance frequencies based on the calculated adjustment amount.
