Gyroscope and input apparatus using the gyroscope that detects displacement of leg of tuning fork by means of capacitance change when angular velocity is entered

摘要

The invention provides a gyroscope that brings about the miniaturization of a device, improvement of detection sensitivity, and reduction of driving voltage. A gyroscope of the present invention is provided with a tuning fork formed of conductive material having a plurality of legs and a support, a top glass substrate and a bottom glass substrate for holding the tuning fork in-between, a plurality of driving electrodes for driving the plurality of legs in capacitance coupling with the legs, and a plurality of detecting electrodes, each detecting electrode is disposed so as to face to the end face of each leg in the extending direction correspondingly to each leg.
