Abstract

PURPOSE:To attain miniaturization and to suppress the increase in the oscillation current and the rise in the oscillation start voltage by constituting an arm being a major component of a couple of vibrations by the connection of flat rod whose length ratio is decided in a specific range and having two kinds of different widths. CONSTITUTION:The segmentation azimuth of a crystal wafer is formed by turning a major plane including the Y axis orthogonal to both the Z and X axes around the X axis by + or -10 deg. or around the Y axis by + or -10 deg.. The vibrator consists of a mount 10, a base 17, arms 15, 16, arm weights 11, 12 and base weights 13, 14. The arm is a flat rod having a width W0 and the arm weights 11, 12 whose length is L1 and whose increment in width is respectively W1, W2 are bonded to the tip. The total length of the arm is L0. Moreover, the size L1/L0 is decided to be 0.3-0.7 and the size of the W1, W2 is made different. Through the constitution above, the design of the shape in the bending and torsional vibrator is facilitated and the separation of undesired vibration is easy and the base turning displace is reduced in the torsional vibration and the exciting electrode split at the side face is formed in the vibration to reduce the series resonance resistor.
