发明名称 RESONATOR, UNIT HAVING RESONATOR, OSCILLATOR HAVING UNIT AND ELECTRONIC APPARATUS HAVING OSCILLATOR
摘要 An electronic apparatus comprises a display portion and at least one oscillating circuit comprising an amplifier, at least one resistor, a plurality of capacitors, and a unit having a case and a resonator. The resonator is vibratable in a flexural mode and has first and second vibrational arms, and at least one groove is formed in at least one of opposite main surfaces of each of the first and second vibrational arms, and at least one mounting arm protrudes from the base portion and extends in a common direction with at least one of the first and second vibrational arms. An output signal of the at least one oscillating circuit comprising the resonator is a clock signal for use in operation of the electronic apparatus to display time information at the display portion.
