Patent ID: 7246520

Claim:
A transducer, comprising: a rod-shaped oscillating reed extending along a first direction, which corresponds to a center axis of rotation of the transducer, to generate a first oscillation to generate a Coriolis force corresponding to the rotation, the oscillating reed including a pair of rod-shaped oscillating reeds extending along the first direction, in parallel to each other; a beam extending in a second direction in parallel with a virtual plane including the oscillating reed and perpendicular to the first direction and being connected to the oscillating reed; a first detecting unit provided on the beam to detect deformation of the beam due to a second oscillation of the oscillating reed caused by the Coriolis force, the first detecting unit being provided between the pair of oscillating reeds; a second detecting unit provided on the beam to detect the deformation of the beam, the first detecting unit and the second detecting unit cooperating to perform detection to eliminate a disturbance for the rotation of the transducer in a third direction perpendicular to the virtual plane; a base member to support the beam; a first connecting device to connect one end of the beam and the base member; a second connecting device to connect the other end of the beam and the base member; and a third connecting device to connect a substantially center portion of the beam and the base member, said first connecting device, said second connecting device, said base member, and said beam defining a closed space.
