Technical Examples
  1. The electronic apparatus comprises a display portion and a quartz crystal oscillator at least, and said electronic apparatus comprises at least two quartz crystal oscillators. Also, each of two quartz crystal oscillators of the at least two oscillators comprises a quartz crystal oscillating circuit having an amplification circuit and a feedback circuit. The feedback circuit is constructed by a flexural mode, quartz crystal tuning fork resonator or a width-extensional mode quartz crystal resonator or a thickness shear mode quartz crystal resonator and for example, the quartz crystal tuning fork resonator comprising tuning fork tines and tuning fork base that are formed integrally, is shown with novel shape and electrode construction. Also, the quartz crystal tuning fork resonator, capable of vibrating in a fundamental mode and having a high frequency stability can be provided with a small series resistance and a high quality factor, even when the tuning fork resonator is miniaturized. This is accomplished by grooves, groove dimensions and electrode construction on the tuning fork tines and/or tuning fork base of the quartz crystal tuning fork resonator. In addition, from a relationship of an amplification rate and a feedback rate, the quartz crystal oscillator having an output signal of a frequency of the fundamental mode vibration for the quartz crystal tuning fork resonator can be provided with the high frequency stability.
