式が検討されている。In recent years, the development of crystal oscillation wristwatches has been remarkable, and currently the mainstream used in crystal oscillation wristwatches is the tuning fork-shaped crystal oscillator, which is more compact and easier to support. As wristwatches become more precise, methods for improving and compensating for changes in oscillation frequency, particularly with respect to temperature changes in crystal resonators, are being studied.
この一つの解決策として零温度係数の異なる二個の水晶
振動子ユニットを使用し温度補償を行なう試みがなされ
実用化の方向にすすんでいる。As one solution to this problem, attempts have been made to perform temperature compensation using two crystal resonator units with different zero temperature coefficients, and progress is being made toward practical use.
しかし、二個の水晶振動子ユニットを使用する場合には
コスト・スペースともに倍となってしまう。However, if two crystal oscillator units are used, both the cost and space will double.
本発明はかかる欠点を除去するためになさ′れたもので

With the goal.

電極パターン１１ｂ、１１ｃは電気的な関係はなく、水
晶振動子を組立後容器のベースに取付はリード線が穴を
貫通することにより複合振動子の機能を発揮する。The electrode patterns 11b and 11c have no electrical relationship, and when the crystal oscillator is assembled and attached to the base of the container, the lead wire passes through the hole, thereby exhibiting the function of a composite oscillator.

As a result, automatic assembly becomes easy and an inexpensive composite vibrator unit can be provided.
また、同一容器に二個の音叉形水晶振動子を封入するた
め小形化に有利である。Furthermore, since two tuning fork crystal oscillators are enclosed in the same container, it is advantageous for miniaturization.
