【考案の詳細な説明】
本考案は携帯用電子時計内部に収容され保持される水晶
振動子の保持手段に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a holding means for a crystal resonator housed and held inside a portable electronic watch.
一般に水晶振動子は、外部からの振動、衝撃に吋して弱
いという欠点を有している。In general, crystal resonators have the disadvantage of being susceptible to external vibrations and shocks.
そこで、例えば腕時計に水晶振動子を組込む場合、その
保持方法に関しては充分考慮する必要がある。Therefore, when incorporating a crystal resonator into a wristwatch, for example, it is necessary to give sufficient consideration to the method of holding the resonator.
ところが、従来の水晶振動子を用いた腕時計においては
、基板に直接固定するか、或は水晶振動子を保持するた
めの特別な取付部品を介して保持する方法が採られてい
る。However, in wristwatches using conventional crystal oscillators, the crystal oscillator is either directly fixed to a substrate or held through a special attachment part for holding the quartz crystal oscillator.
前者の場合には、どうしても外部からの影響を受は易す
く信頼性の高い振動周波数を得ることが困難であり、又
後者の場合は信頼性の面では高くなるものの、特別な取
付部品を必要とする。In the former case, it is easy to be influenced by external influences and it is difficult to obtain a reliable vibration frequency, and in the latter case, although the reliability is high, special mounting parts are required. shall be.
本考案は上記欠点に鑑み、水晶振動子の固定を容易かつ
確実にし、しかも高信頼性の振動周波数を得るようにし
た保持装置を提供することを目的とする。SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a holding device that allows a crystal resonator to be fixed easily and reliably, and that also provides a highly reliable vibration frequency.
以下本考案の実施例を図面と共に詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.

口に蓋をするための受板である。Figure 1 is a cross-sectional view showing the movement of an electronic wristwatch. In the figure, 1 is a housing that constitutes the outer shape of the movement, 2 is a board to which electronic components are connected and wired, and 3 is a display device consisting of a liquid crystal display or other display means. , 4 is a receiving plate for covering the upper opening of the housing 1 after the substrate 2 and display device 3 are assembled into the housing 1.
一方、ハウジング１には水晶振動子５を収納するための
収容部６を設けている。On the other hand, the housing 1 is provided with an accommodating portion 6 for accommodating the crystal resonator 5.
この収容部にはハウジング１と一体的に形成された弾性
を有する突片７を設けている。This accommodation portion is provided with an elastic protrusion 7 formed integrally with the housing 1.
この突片７は丁度片持ち支持の役目を果す構造となって
おり、水晶振動子５の収容部６への挿入前は第２図ａの
様になっている。This protruding piece 7 has a structure that just serves as a cantilever support, and the crystal resonator 5 is as shown in FIG. 2a before being inserted into the accommodating portion 6.
上述した収容部６に水晶振動子５を挿入すると突片７と
接触し、さらにその上部より受板４を押し込むと、突片
Ｉと水晶振動子５の接触点に集中荷重が加わり、突片１
は片持ちの原理によってたわむ。When the crystal resonator 5 is inserted into the above-mentioned housing part 6, it comes into contact with the protruding piece 7, and when the receiving plate 4 is further pushed in from above, a concentrated load is applied to the contact point between the protruding piece I and the crystal resonator 5, and the protruding piece 1
deflects according to the cantilever principle.
この時、弾性により突片１は元に戻ろうとするが、ムー
ブメントの受板４によって水晶振動子５の上端部が押え
られるため、水晶振動子５は動くことができず、確実に
固定される。At this time, the protruding piece 1 tries to return to its original position due to its elasticity, but the upper end of the crystal oscillator 5 is held down by the movement's receiving plate 4, so the crystal oscillator 5 cannot move and is securely fixed. .
このように片持ちのたわみを利用すると、水晶振動子５
の外型のバラツキも吸収され、確実に固定されるので信
頼性の高い振動周波数を得ることができる。By using the cantilever deflection in this way, the crystal unit 5
Variations in the outer shape are also absorbed, and it is securely fixed, making it possible to obtain a highly reliable vibration frequency.
しかも伺ら特別な取付部品を用いる必要がないので組立
も大変容易である。Moreover, it is very easy to assemble since there is no need to use special mounting parts.
上述のことから、本考案による方法を用いることで、従
来のものに比し、高精度、高信頼性の腕時計を得ること
ができる。From the above, by using the method according to the present invention, it is possible to obtain a wristwatch with higher precision and higher reliability than the conventional one.
