Patent ID: 7000472

Claim:
A vibrator supporting mechanism for supporting a gyro-vibrator spatially apart from a substrate along a first and/or second direction with the gyro-vibrator comprising a drive section to which a Coriolis force is applied upon an angular rotation of the gyro-vibrator with the drive section vibrating in a first direction, a detection section vibrating in a second direction perpendicular to said first direction in response to said Coriolis force and said gyro-vibrator rotating about an axis in a third direction perpendicular to said first and second directions and a support section for supporting said drive section and said detection section relative to the substrate, wherein: the drive section comprises a first and a second drive arm disposed parallel to each other; the detection section comprises a detection arm disposed between and parallel to the first and the second drive arm sections; and having an arm supporting section with opposite ends in which one end is connected to the first drive arm section, the opposite end connected to the second drive arm section, and with the arm supporting section connected at an intermediate location to the detection arm; and wherein the vibrator supporting mechanism comprises a first elastic mechanism for supporting the arm supporting section along either said first or second directions and having a characteristic resonance frequency of vibration along the first direction that is lower than the characteristic resonance frequency of vibration along the third direction.
