Description

この発明は、時計、携帯電話機、携帯端末機などの電子機器に用いられるスイッチ装置およびそれを備えた時計に関する。   The present invention relates to a switch device used in electronic equipment such as a timepiece, a mobile phone, and a mobile terminal, and a timepiece including the same.

例えば、腕時計のスイッチ装置においては、特許文献1に記載されているように、腕時計ケースの取付孔に取付パイプを嵌め込み、この取付パイプに釦部材の軸部をスライド可能に挿入し、この取付パイプから外部に突出する釦部材の軸部およびこの軸部の外端部の頭部を防水シートで覆い、この防水シートを腕時計ケースの外面に固定部材によって取り付けることにより、防水性を図った構成のものが知られている。   For example, in a wristwatch switch device, as described in Patent Document 1, a mounting pipe is fitted into a mounting hole of a wristwatch case, and a shaft portion of a button member is slidably inserted into the mounting pipe. The shaft portion of the button member that protrudes from the outside and the head of the outer end portion of the shaft portion are covered with a waterproof sheet, and the waterproof sheet is attached to the outer surface of the watch case with a fixing member, thereby achieving a waterproof structure. Things are known.

特開2009−133859号公報JP 2009-133859 A

この種のスイッチ装置は、防水シートがウレタン樹脂やシリコーン樹脂などの軟質の合成樹脂で形成され、釦部材が押圧操作された際に、その押圧操作に応じて防水シートが弾性変形し、この防水シートの弾性変形に伴って釦部材がスライドすることにより、腕時計ケース内のスイッチ接点をスイッチ動作させるように構成されている。   In this type of switch device, the waterproof sheet is formed of a soft synthetic resin such as urethane resin or silicone resin, and when the button member is pressed, the waterproof sheet is elastically deformed in response to the pressing operation. When the button member slides with the elastic deformation of the seat, the switch contact in the watch case is switched.

しかしながら、このようなスイッチ装置では、防水シートの肉厚が厚いと、防水シートが弾性変形し難く、釦部材を押圧操作する際の押圧荷重が重くなるため、釦部材の操作性が低下するという問題がある。また、防水シートの肉厚が薄いと、防水シートが弾性変形し易くなるが、防水シートが破損し易くなるため、防水性を確保することが難しくなるという問題がある。さらに、防水シートが軟質の合成樹脂であるため、防水シートの肉厚が厚くても、また薄くても、劣化し易いという問題がある。   However, in such a switch device, if the waterproof sheet is thick, the waterproof sheet is not easily elastically deformed, and the pressing load when the button member is pressed increases, so that the operability of the button member is reduced. There's a problem. Further, if the thickness of the waterproof sheet is thin, the waterproof sheet is easily elastically deformed, but the waterproof sheet is liable to be damaged, which makes it difficult to ensure waterproofness. Furthermore, since the waterproof sheet is a soft synthetic resin, there is a problem that the waterproof sheet is easily deteriorated even if the waterproof sheet is thick or thin.

この発明が解決しようとする課題は、防水性を確保し、かつ操作性の向上を図ることができるスイッチ装置およびそれを備えた時計を提供することである。   The problem to be solved by the present invention is to provide a switch device capable of ensuring waterproofness and improving operability, and a timepiece including the same.

この発明は、小径孔部および大径孔部を有する貫通孔が設けられたケースと、このケースの前記大径孔部に配置された筒状のガイド部材と、前記ケースの前記小径孔部内にスライド可能に挿入する軸部および前記ガイド部材内にスライド可能に配置される頭部を有する操作部材と、この操作部材の前記頭部の外周面と前記ガイド部材の内周面との間に設けられた防水部材と、前記ガイド部材の内部と外部とを通気する通気部および前記ガイド部材の外周面と前記ケースの前記大径孔部の内周面との間に配置された通気フィルタを通して、前記ガイド部材内の空気と前記ケースの外部の空気とを通気させる通気路と、を備えていることを特徴とするスイッチ装置である。   The present invention includes a case provided with a through hole having a small diameter hole portion and a large diameter hole portion, a cylindrical guide member disposed in the large diameter hole portion of the case, and the small diameter hole portion of the case. An operating member having a shaft portion slidably inserted and a head slidably disposed in the guide member, and provided between the outer peripheral surface of the head of the operating member and the inner peripheral surface of the guide member Through the waterproof member, the ventilation portion that ventilates the inside and outside of the guide member, and the ventilation filter disposed between the outer peripheral surface of the guide member and the inner peripheral surface of the large-diameter hole portion of the case, A switch device comprising an air passage for ventilating air in the guide member and air outside the case.

この発明によれば、防水部材によってガイド部材の内周面と操作部材の頭部の外周面との間の防水性および気密性を確保することができる共に、通気路の通気部と通気フィルタとによって、ガイド部材内の空気とケースの外部の空気とを通気させることができるので、ガイド部材内の気圧をケースの外部の気圧とほぼ同じに保つことができる。このため、防水部材によって防水性および気密性を確保しても、操作部材の操作性を向上させることができる。   According to the present invention, the waterproof member can ensure waterproofness and airtightness between the inner peripheral surface of the guide member and the outer peripheral surface of the head of the operation member, and the ventilation portion and the ventilation filter of the ventilation path can be secured. Thus, the air inside the guide member and the air outside the case can be ventilated, so that the air pressure inside the guide member can be kept substantially the same as the air pressure outside the case. For this reason, even if waterproofness and airtightness are ensured by the waterproof member, the operability of the operation member can be improved.

The first small diameter hole 12 a is formed on the inner side of the main body case 2. The second small diameter hole portion 12 b is formed on the outer side of the main body case 2. The second small diameter hole portion 12 b is formed so that its inner diameter is larger than the inner diameter of the first small diameter hole portion 12 a and smaller than the inner diameter of the large diameter hole portion 13. The small-diameter hole 12 is formed so that its axial length is approximately half the wall thickness of the main body case 2.

また、貫通孔10の大径孔部13は、図2および図5に示すように、小径孔部12の第2小径孔部12bの内径よりも大きく形成されている。この大径孔部13は、その軸方向の長さが小径孔部12の軸方向の長さとほぼ同じか、それよりも少し短く形成されている。これにより、貫通孔10は、小径孔部12の第2小径孔部12bと大径孔部13との境界部に段差部15が設けられた構成になっている。   Moreover, the large diameter hole part 13 of the through-hole 10 is formed larger than the internal diameter of the 2nd small diameter hole part 12b of the small diameter hole part 12, as shown in FIG.2 and FIG.5. The large-diameter hole 13 is formed so that its axial length is substantially the same as or slightly shorter than the axial length of the small-diameter hole 12. Thereby, the through hole 10 has a configuration in which a step portion 15 is provided at a boundary portion between the second small diameter hole portion 12 b and the large diameter hole portion 13 of the small diameter hole portion 12.

さらに、貫通孔10の外装孔部14は、図2および図5に示すように、その内径が大径孔部13の内径よりも少し小さく形成されている。この外装孔部14の周囲における円周方向の両側部に位置する外装ケース3の外面には、後述する操作部材11の頭部18を保護する保護突起部16が、腕時計ケース1の外部に向けて突出して設けられている。   Further, as shown in FIGS. 2 and 5, the exterior hole portion 14 of the through hole 10 is formed so that its inner diameter is slightly smaller than the inner diameter of the large-diameter hole portion 13.

That is, the plurality of waterproof rings 20 are each provided in an annular shape in the second small diameter hole portion 12 b in the small diameter hole portion 12 of the through hole 10. Thus, the plurality of waterproof rings 20 are slidably pressed against the outer peripheral surface of the shaft portion 17, and in this state, the outer peripheral surface of the shaft portion 17 slides as the shaft portion 17 slides. ing.

また、この軸部17の外端部には、図2〜図4に示すように、頭部18が一体に設けられている。この頭部18は、全体がほぼ円筒状に形成され、貫通孔10の大径孔部13と外装孔部14との両方に跨って配置されるように構成されている。すなわち、この頭部18は、その軸方向の長さが大径孔部13の軸方向の長さと外装孔部14の軸方向の長さとの両方の長さとほぼ同じ長さに形成されている。   Further, as shown in FIGS. 2 to 4, a head portion 18 is integrally provided at the outer end portion of the shaft portion 17. The head portion 18 is formed in a substantially cylindrical shape as a whole, and is configured to be disposed across both the large-diameter hole portion 13 and the exterior hole portion 14 of the through hole 10. That is, the head 18 is formed so that its axial length is substantially the same as both the axial length of the large-diameter hole 13 and the axial length of the exterior hole 14. .

これにより、頭部18は、図2および図5に示すように、軸部17の抜止め部材19が本体ケース2の内周面に当接した際に、大径孔部13内から外装孔部14内に向けて押し出されることにより、頭部18の内端部18aが貫通孔10の段差部15から離れた状態で配置されると共に、頭部18の外端部18bが外装孔部14から腕時計ケース1の外部に向けて押し出されて腕時計ケース1の外部に突出するように構成されている。   As a result, as shown in FIG. 2 and FIG. 5, when the retaining member 19 of the shaft portion 17 comes into contact with the inner peripheral surface of the main body case 2, By being pushed out into the portion 14, the inner end portion 18 a of the head portion 18 is arranged in a state of being separated from the step portion 15 of the through hole 10, and the outer end portion 18 b of the head portion 18 is arranged in the exterior hole portion 14. It is configured to be pushed out from the watch case 1 to protrude outside the watch case 1.

The inner end 18a of the timepiece module 6 presses the switch contact 6a of the timepiece module 6, and the inner end 18a of the head 18 is pushed into the large-diameter hole 13 so as to be close to the stepped portion 15. The outer end 18b of the head 18 is arranged at a position where it is pushed into the exterior hole 14.

この場合、腕時計ケース1の貫通孔10の大径孔部13内には、図2〜図5に示すように、円筒状のガイド部材21が円筒状の通気フィルタ22を介して装着されている。このガイド部材21は、その内径が頭部18の外径よりも少し大きく、かつ外装孔部14の内径よりも少し小さく形成されている。また、このガイド部材21は、その外径が外装孔部14の内径よりも少し大きく、かつ大径孔部13の内径よりも小さく形成されている。さらに、このガイド部材21は、その軸方向の長さが大径孔部13の軸方向の長さとほぼ同じ長さに形成されている。   In this case, a cylindrical guide member 21 is mounted in the large-diameter hole 13 of the through hole 10 of the watch case 1 via a cylindrical ventilation filter 22 as shown in FIGS. . The guide member 21 is formed so that its inner diameter is slightly larger than the outer diameter of the head 18 and slightly smaller than the inner diameter of the exterior hole portion 14. Further, the guide member 21 has an outer diameter that is slightly larger than the inner diameter of the exterior hole portion 14 and smaller than the inner diameter of the large-diameter hole portion 13. Further, the guide member 21 has an axial length that is substantially the same as the axial length of the large-diameter hole 13.

また、このガイド部材21は、図2および図5に示すように、位置規制部によって貫通孔10の大径孔部13内に位置規制されるように構成されている。この位置規制部は、貫通孔10の小径孔部12と大径孔部13との境界部に位置してガイド部材21の内端部が当接する段差部15と、貫通孔10の大径孔部13の外端部に位置してガイド部材21の外端部が当接する腕時計ケース1の外装ケース3と、を備えている。   Further, as shown in FIGS. 2 and 5, the guide member 21 is configured such that the position of the guide member 21 is regulated within the large-diameter hole 13 of the through hole 10 by the position regulating unit. The position restricting portion is located at a boundary portion between the small diameter hole portion 12 and the large diameter hole portion 13 of the through hole 10 and the stepped portion 15 with which the inner end portion of the guide member 21 abuts, and the large diameter hole of the through hole 10. And an outer case 3 of the watch case 1 that is located at the outer end of the portion 13 and abuts against the outer end of the guide member 21.

すなわち、この位置規制部は、図2および図5に示すように、ガイド部材21が大径孔部13内に通気フィルタ22と共に嵌め込まれた際に、ガイド部材21の内端部が貫通孔10の段差部15に当接し、ガイド部材21の外端部が外装ケース3の外装孔部14の内側縁部に当接することにより、ガイド部材21を大径孔部13内に位置規制するように構成されている。   That is, as shown in FIGS. 2 and 5, when the guide member 21 is fitted into the large-diameter hole portion 13 together with the ventilation filter 22, the position restricting portion has the inner end portion of the guide member 21 formed in the through hole 10. So that the outer end of the guide member 21 contacts the inner edge of the exterior hole 14 of the exterior case 3 so that the position of the guide member 21 is regulated within the large-diameter hole 13.

External air is sent between the outer peripheral surface of the guide member 21 and the inner peripheral surface of the outer case 3 through the space between the inner peripheral surface of the outer hole portion 14 and the outer peripheral surface of the head portion 18. Air is configured to be fed into the guide member 21 from a ventilation portion 28 provided at an inner end portion of the guide member 21 through the ventilation filter 22.

次に、このような腕時計におけるスイッチ装置8の作用について説明する。
このスイッチ装置8は、通常の状態で、ガイド部材21内に位置する操作部材11の軸部17の外周に沿って配置されたコイルばね25のばね力によって、頭部18が腕時計ケース1の外部に向けて押し出されている。
Next, the operation of the switch device 8 in such a wristwatch will be described.
In the normal state, the switch device 8 is configured such that the head 18 is outside the watch case 1 by the spring force of the coil spring 25 disposed along the outer periphery of the shaft portion 17 of the operation member 11 located in the guide member 21. It is pushed out towards

この状態では、本体ケース2の内部に突出している操作部材11の軸部17における内端部に設けられた抜止め部材19が、貫通孔10の第1小径孔部12aにおける内端部の周囲に位置する本体ケース2の内周面に当接する。また、この状態では、操作部材11の頭部18の内端部18aが貫通孔10の段差部15から腕時計ケース1の外部側に離れて、頭部18の外端部18bが第2筒部18から腕時計ケース1の外部に突出している。   In this state, the retaining member 19 provided at the inner end portion of the shaft portion 17 of the operation member 11 protruding inside the main body case 2 is around the inner end portion of the first small diameter hole portion 12a of the through hole 10. It abuts on the inner peripheral surface of the main body case 2 located at the position. In this state, the inner end 18a of the head 18 of the operation member 11 is separated from the stepped portion 15 of the through hole 10 to the outside of the watch case 1, and the outer end 18b of the head 18 is the second cylindrical portion. 18 protrudes from the wristwatch case 1 to the outside.

これにより、操作部材11の軸部17の内端部が、時計モジュール6に設けられたスイッチ接点部6aから離れ、このスイッチ接点部6aがオフ状態になっている。この状態で、操作部材11の頭部18をコイルばね25のばね力に抗して押圧操作すると、操作部材11の頭部18がガイド部材21内に押し込まれると共に、軸部17が貫通孔10の小径孔部12内を本体ケース2の内部に向けてスライドする。   As a result, the inner end portion of the shaft portion 17 of the operation member 11 is separated from the switch contact portion 6a provided in the timepiece module 6, and the switch contact portion 6a is in an OFF state. When the head 18 of the operation member 11 is pressed against the spring force of the coil spring 25 in this state, the head 18 of the operation member 11 is pushed into the guide member 21 and the shaft portion 17 is inserted into the through hole 10. The small-diameter hole 12 is slid toward the inside of the main body case 2.

このときには、軸部17の外周面が貫通孔10の第2小径孔部12b内に設けられた複数の防水リング20に圧接した状態で摺動する。同様に、頭部18の外周面に設けられた防水部材24がガイド部材21の内周面に圧接した状態で摺動する。このため、防水部材24によって頭部18の外周面とガイド部材21の内周面との間からガイド部材21内に、腕時計ケース1の外部の水や泥などの異物が浸入することがなく、ガイド部材21内の防水性および気密性が図られる。   At this time, the outer peripheral surface of the shaft portion 17 slides in a state of being pressed against the plurality of waterproof rings 20 provided in the second small diameter hole portion 12 b of the through hole 10. Similarly, the waterproof member 24 provided on the outer peripheral surface of the head 18 slides in a state of being pressed against the inner peripheral surface of the guide member 21. Therefore, foreign matter such as water and mud outside the watch case 1 does not enter the guide member 21 from between the outer peripheral surface of the head 18 and the inner peripheral surface of the guide member 21 by the waterproof member 24. Waterproofness and airtightness in the guide member 21 are achieved.

また、このときには、貫通孔10内におけるガイド部材21と操作部材11の頭部18と小径孔部12内の複数の防水リング20とで囲われた領域であるガイド部材21内の空気が、本体ケース2の内部に向けてスライドする頭部18のスライドに応じて、徐々に圧縮されて、空気圧が高くなる。この圧縮された空気は、通気路27を通して腕時計ケース1の外部に排出される。   At this time, the air in the guide member 21, which is a region surrounded by the guide member 21 in the through hole 10, the head 18 of the operation member 11, and the plurality of waterproof rings 20 in the small-diameter hole 12, As the head 18 slides toward the inside of the case 2, the head 18 is gradually compressed to increase the air pressure. The compressed air is discharged to the outside of the watch case 1 through the air passage 27.

すなわち、圧縮された空気は、ガイド部材21の内端部に設けられた複数の通気溝である通気部28からガイド部材21の外周面と大径孔部13の内周面との間に配置された通気フィルタ22に送り込まれる。この送り込まれた空気は、通気フィルタ22を通してガイド部材21の外端部と外装ケース3の内面との間から外装孔部14内に送り込まれる。   That is, the compressed air is disposed between the outer peripheral surface of the guide member 21 and the inner peripheral surface of the large-diameter hole portion 13 from the ventilation portion 28 which is a plurality of ventilation grooves provided at the inner end portion of the guide member 21. Sent to the vent filter 22. The sent air is sent into the exterior hole portion 14 from between the outer end portion of the guide member 21 and the inner surface of the exterior case 3 through the ventilation filter 22.

この外装孔部14内に送り込まれた空気は、外装孔部14の内周面と頭部18の外周面との間から腕時計ケース1の外部に排出される。このため、貫通孔10内におけるガイド部材21と操作部材11の頭部18と小径孔部12内の複数の防水リング20とで囲われた領域であるガイド部材21内の空気圧は、頭部18がスライド動作しても、腕時計ケース1の外部の気圧とほぼ同じに保たれる。   The air sent into the exterior hole 14 is discharged to the outside of the watch case 1 from between the inner peripheral surface of the exterior hole 14 and the outer peripheral surface of the head 18. For this reason, the air pressure in the guide member 21, which is an area surrounded by the guide member 21 in the through hole 10, the head 18 of the operation member 11, and the plurality of waterproof rings 20 in the small diameter hole 12, Even if the slide operation, the atmospheric pressure outside the watch case 1 is kept substantially the same.

これにより、操作部材11の頭部18を押圧操作した際に、貫通孔10内におけるガイド部材21と操作部材11の頭部18と小径孔部12内の複数の防水リング20とで囲われた領域であるガイド部材21内の空気が圧縮されても、操作部材11を円滑にかつ良好にスライドさせることができる。このときには、操作部材11のスライドに伴って軸部17の内端部が本体ケース2内に押し込まれ、この軸部17の内端部によって時計モジュール6のスイッチ接点部6aが押されてオン動作する。   Thereby, when the head 18 of the operation member 11 is pressed, the guide member 21 in the through hole 10, the head 18 of the operation member 11, and the plurality of waterproof rings 20 in the small diameter hole 12 are surrounded. Even if the air in the guide member 21 that is the region is compressed, the operation member 11 can be smoothly and satisfactorily slid. At this time, the inner end portion of the shaft portion 17 is pushed into the main body case 2 as the operating member 11 slides, and the switch contact portion 6a of the timepiece module 6 is pushed by the inner end portion of the shaft portion 17 to turn on. To do.

一方、スイッチ接点部6aが押されてオン動作した後は、ガイド部材21内に位置する操作部材11の軸部17の外周に沿って配置されたコイルばね25のばね力によって、頭部18が腕時計ケース1の外部に向けて押し出される。このときには、操作部材11の軸部17が、貫通孔10の小径孔部12内を腕時計ケース1の外部に向けてスライドする。このときにも、軸部17の外周面が小径孔部12の第2小径孔部12bに設けられた複数の防水リング20に圧接した状態で摺動する。   On the other hand, after the switch contact portion 6 a is pressed and turned on, the head 18 is moved by the spring force of the coil spring 25 arranged along the outer periphery of the shaft portion 17 of the operation member 11 located in the guide member 21. Pushed toward the outside of the watch case 1. At this time, the shaft portion 17 of the operation member 11 slides inside the small diameter hole portion 12 of the through hole 10 toward the outside of the watch case 1. Also at this time, the outer peripheral surface of the shaft portion 17 slides in a state of being pressed against the plurality of waterproof rings 20 provided in the second small diameter hole portion 12b of the small diameter hole portion 12.

また、このときにも、操作部材11の頭部18の外周面に設けられた防水部材24がガイド部材21の内周面に圧接した状態で摺動する。このため、防水部材24によって頭部18の外周面とガイド部材21の内周面との間からガイド部材21内に、腕時計ケース1の外部の水や泥などの異物が浸入することがなく、ガイド部材21内の防水性および気密性が図られる。   Also at this time, the waterproof member 24 provided on the outer peripheral surface of the head 18 of the operation member 11 slides in a state of being pressed against the inner peripheral surface of the guide member 21. Therefore, foreign matter such as water and mud outside the watch case 1 does not enter the guide member 21 from between the outer peripheral surface of the head 18 and the inner peripheral surface of the guide member 21 by the waterproof member 24. Waterproofness and airtightness in the guide member 21 are achieved.

このときには、貫通孔10内におけるガイド部材21と操作部材11の頭部18と小径孔部12内の複数の防水リング20とで囲われた領域であるガイド部材21内の空気が、腕時計ケース1の外部に向けてスライドする頭部18のスライドに応じて、徐々に膨張して、空気圧が下がる。このように空気圧が徐々に下がる際には、腕時計ケース1の外部の空気が通気路27を通してガイド部材21内に送り込まれる。   At this time, the air in the guide member 21, which is a region surrounded by the guide member 21 in the through hole 10, the head 18 of the operation member 11, and the plurality of waterproof rings 20 in the small diameter hole portion 12, is watch case 1. As the head 18 slides toward the outside, the air gradually expands and the air pressure decreases. Thus, when the air pressure gradually decreases, the air outside the watch case 1 is sent into the guide member 21 through the air passage 27.

すなわち、腕時計ケース1の外部の空気は、外装孔部14の内周面と頭部18の外周面との間からガイド部材21の外端部と外装ケース3の内面との間に取り込まれ、この取り込まれた空気は、通気フィルタ22に送り込まれる。この通気フィルタ22に送り込まれた空気は、通気フィルタ22を通してガイド部材21の内端部に設けられた複数の通気溝である通気部28からガイド部材21内に送り込まれる。   That is, the air outside the watch case 1 is taken in between the outer end of the guide member 21 and the inner surface of the outer case 3 from between the inner peripheral surface of the outer hole 14 and the outer peripheral surface of the head 18. This taken-in air is sent to the ventilation filter 22. The air sent into the ventilation filter 22 is sent into the guide member 21 through the ventilation filter 22 from the ventilation portion 28 which is a plurality of ventilation grooves provided at the inner end portion of the guide member 21.

これにより、貫通孔10内におけるガイド部材21と操作部材11の頭部18と小径孔部12内の複数の防水リング20とで囲われた領域であるガイド部材21内の空気圧は、腕時計ケース1の外部の空気が頭部18がスライド動作に伴ってガイド部材21内に取り込まれることにより、頭部18がスライド動作しても、腕時計ケース1の外部の気圧とほぼ同じに保たれる。   As a result, the air pressure in the guide member 21, which is an area surrounded by the guide member 21 in the through hole 10, the head 18 of the operation member 11, and the plurality of waterproof rings 20 in the small-diameter hole portion 12, is When the head 18 is taken into the guide member 21 as the head 18 slides, the air pressure outside the wristwatch case 1 is kept substantially the same even when the head 18 slides.

このため、コイルばね25のばね力によって操作部材11が元の位置に戻る際には、貫通孔10内におけるガイド部材21と操作部材11の頭部18と小径孔部12内の複数の防水リング20とで囲われた領域であるガイド部材21内の空気が膨張して空気圧が下っても、操作部材11を円滑にかつ良好にスライドさせることができる。このときには、操作部材11のスライドに伴って軸部17の内端部が時計モジュール6のスイッチ接点部6aから離れ、スイッチ接点部6aがオフ状態になる。   For this reason, when the operating member 11 returns to the original position by the spring force of the coil spring 25, the guide member 21 in the through hole 10, the head 18 of the operating member 11, and the plurality of waterproof rings in the small diameter hole portion 12. The operating member 11 can be smoothly and satisfactorily slid even when the air in the guide member 21, which is an area surrounded by the reference numeral 20, expands and the air pressure decreases. At this time, as the operating member 11 slides, the inner end portion of the shaft portion 17 moves away from the switch contact portion 6a of the timepiece module 6, and the switch contact portion 6a is turned off.

このように、この腕時計のスイッチ装置8によれば、小径孔部12と大径孔部13とを有する貫通孔10が設けられた腕時計ケース1と、大径孔部13に配置された筒状のガイド部材21と、小径孔部12内にスライド可能に挿入する軸部17およびガイド部材21内にスライド可能に配置される頭部18を有する操作部材11と、頭部18の外周面とガイド部材21の内周面との間に設けられた防水部材24と、ガイド部材21の通気部28およびガイド部材21と大径孔部13との間の通気フィルタ22を通して、ガイド部材21内の空気と腕時計ケース1の外部の空気とを通気させる通気路27と、を備えているので、防水性を確保し、かつ操作性の向上を図ることができる。   Thus, according to this wristwatch switch device 8, the wristwatch case 1 provided with the through hole 10 having the small diameter hole portion 12 and the large diameter hole portion 13, and the cylindrical shape disposed in the large diameter hole portion 13. The guide member 21, the shaft portion 17 slidably inserted into the small-diameter hole portion 12, the operation member 11 having the head 18 slidably disposed in the guide member 21, the outer peripheral surface of the head 18 and the guide The air in the guide member 21 passes through the waterproof member 24 provided between the inner peripheral surface of the member 21, the ventilation portion 28 of the guide member 21 and the ventilation filter 22 between the guide member 21 and the large-diameter hole portion 13. And the air passage 27 for allowing the air outside the watch case 1 to ventilate, it is possible to ensure waterproofness and improve operability.

すなわち、この腕時計のスイッチ装置8では、防水部材24によってガイド部材21の内周面と操作部材11の頭部18の外周面との間の防水性および気密性を確保することができる共に、通気部28と通気フィルタ22とで構成された通気路27によって、ガイド部材21内の空気と腕時計ケース1の外部の空気とを通気させることができるので、ガイド部材21内の空気圧を腕時計ケース1の外部の気圧とほぼ同じに保つことができる。このため、防水部材24によって防水性および気密性を確保しても、操作部材11の操作性を向上させることができる。   That is, in the wristwatch switch device 8, the waterproof member 24 can ensure waterproofness and airtightness between the inner peripheral surface of the guide member 21 and the outer peripheral surface of the head portion 18 of the operation member 11, and also allows ventilation. The air passage 27 formed by the portion 28 and the ventilation filter 22 can ventilate the air in the guide member 21 and the air outside the watch case 1, so that the air pressure in the guide member 21 is changed to the air pressure in the watch case 1. It can be kept almost the same as the external atmospheric pressure. For this reason, even if waterproofness and airtightness are ensured by the waterproof member 24, the operability of the operation member 11 can be improved.

また、このスイッチ装置8では、ガイド部材21内に仮に水などの液体が浸入しても、その浸入した水などの液体を通気フィルタ22の毛細管現象によって腕時計ケース1の外部に排出することができる。このため、ガイド部材21内に水などの液体が溜まることがないので、防錆効果があるほか、操作部材11の操作性を、より一層、確保することができ、これにより操作部材11を良好にかつ円滑に操作させることができる。   Further, in this switch device 8, even if a liquid such as water enters the guide member 21, the liquid such as water that has entered can be discharged to the outside of the watch case 1 by the capillary phenomenon of the ventilation filter 22. . For this reason, since liquids, such as water, do not accumulate in the guide member 21, in addition to having a rust prevention effect, the operability of the operation member 11 can be further ensured, thereby making the operation member 11 better. And can be operated smoothly.

この場合、通気部28は、操作部材11の頭部18がガイド部材21内に押し込まれた際に、頭部18の内端部18aよりも腕時計ケース1の内部側に位置するガイド部材21の箇所、つまりガイド部材21の内端部に設けられていることにより、操作部材11の頭部18がガイド部材21内をスライドしても、頭部18によって通気部28が塞がれることがない。このため、操作部材11の頭部18のスライド動作に応じて、ガイド部材21内の空気と腕時計ケース1の外部の空気とを確実にかつ良好に通気することができる。   In this case, when the head 18 of the operation member 11 is pushed into the guide member 21, the ventilation portion 28 is provided on the guide member 21 located on the inner side of the wristwatch case 1 with respect to the inner end 18 a of the head 18. By being provided at the location, that is, the inner end portion of the guide member 21, even if the head portion 18 of the operation member 11 slides inside the guide member 21, the ventilation portion 28 is not blocked by the head portion 18. . For this reason, the air in the guide member 21 and the air outside the watch case 1 can be surely and satisfactorily ventilated according to the sliding movement of the head 18 of the operation member 11.

また、このスイッチ装置8では、防水部材24が操作部材11の頭部18の外周に設けられ、この状態で貫通孔10の大径孔部13内に配置されたガイド部材21の内周面に圧接した状態で摺動することにより、操作部材11のスライド動作に応じて防水部材24がガイド部材21の内周面に沿って移動しても、ガイド部材21の内周面と操作部材11の頭部18の外周面との間の防水性および気密性を確保することができる。   Further, in the switch device 8, the waterproof member 24 is provided on the outer periphery of the head 18 of the operation member 11, and in this state, on the inner peripheral surface of the guide member 21 disposed in the large-diameter hole portion 13 of the through hole 10.

The ventilation filter 36 has an inner diameter that is substantially the same as the outer diameter of the guide member 36, and an outer diameter that is substantially the same as the inner diameter of the large-diameter hole 13.

また、この通気フィルタ36は、図6〜図9に示すように、その軸方向の長さがガイド部材36の軸方向の長さ、または大径孔部13の軸方向の長さよりも少し短い長さ、つまりフランジ部40の軸方向の長さ(厚み)だけ短い長さで形成されている。これにより、通気フィルタ36は、ガイド部材35の外周面に装着され、この状態でガイド部材35と共に大径孔部13内に挿入されることにより、ガイド部材35と大径孔部13との間の隙間に嵌め込まれて配置されるように構成されている。   Further, as shown in FIGS. 6 to 9, the ventilation filter 36 has a length in the axial direction slightly shorter than the length in the axial direction of the guide member 36 or the length in the axial direction of the large-diameter hole portion 13. The length, i.e., the length (thickness) of the flange portion 40 in the axial direction is short. As a result, the ventilation filter 36 is mounted on the outer peripheral surface of the guide member 35, and is inserted into the large-diameter hole 13 together with the guide member 35 in this state, so that the gap between the guide member 35 and the large-diameter hole 13 is reached. It is comprised so that it may be fitted and arrange | positioned in the clearance gap.

この場合、ガイド部材35のフランジ部40には、図6〜図10に示すように、通気フィルタ36の外端部の一部を外部に露呈させるための複数の切欠き部40aが設けられている。これにより、通気路27は、通気フィルタ36の外端部がガイド部材35のフランジ部40で塞がれていても、ガイド部材35の通気部28、通気フィルタ36、およびフランジ部40の複数の切欠き部40aを通して、ガイド部材35内の空気と腕時計ケース1の外部の空気とを通気させるように構成されている。   In this case, as shown in FIGS. 6 to 10, the flange portion 40 of the guide member 35 is provided with a plurality of notches 40 a for exposing a part of the outer end portion of the ventilation filter 36 to the outside.

Thereby, even if the outer end portion of the ventilation filter 36 is closed by the flange portion 40 of the guide member 35, the ventilation path 27 has a plurality of ventilation portions 28, ventilation filters 36, and flange portions 40 of the guide member 35. The air in the guide member 35 and the air outside the watch case 1 are ventilated through the notch 40a.

すなわち、この通気路27は、図6に示すように、操作部材11の頭部37が本体ケース2内に向けて押し込まれる際に、ガイド部材35内の空気が、ガイド部材35の内端部に設けられた通気部28を通して通気フィルタ36に送り込まれ、この送り込まれた空気が、通気フィルタ36を通り、ガイド部材351のフランジ部40に設けられた複数の切欠き部40aからガイド部材35の外端部と外装ケース3の内周面との間に送り込まれ、この送り込まれた空気が外装孔部14内を経て外装孔部14の内周面と頭部37の外周面との間から腕時計ケース1の外部に排出されるように構成されている。   That is, as shown in FIG. 6, when the head 37 of the operation member 11 is pushed into the main body case 2, the air passage 27 causes the air in the guide member 35 to flow into the inner end portion of the guide member 35. The air is sent to the ventilation filter 36 through the ventilation portion 28 provided in the air passage. The air thus supplied passes through the ventilation filter 36 and passes through the ventilation filter 36 to form the guide member 35 from the plurality of notches 40a provided in the flange portion 40 of the guide member 351. The air is sent between the outer end portion and the inner peripheral surface of the outer case 3, and the sent air passes through the outer hole portion 14 from between the inner peripheral surface of the outer hole portion 14 and the outer peripheral surface of the head portion 37. The watch case 1 is configured to be discharged to the outside.

また、この通気路27は、図6に示すように、操作部材11の頭部37がコイルばね25のばね力によって本体ケース2の外部に向けて押し出される際に、腕時計ケース1の外部の空気が、外装孔部14の内周面と頭部37の外周面との間を通して外装孔部14内に送り込まれ、この送り込まれた空気がガイド部材35の外端部と外装ケース3の内周面との間を経てフランジ部40の複数の切欠き部40aから通気フィルタ36に送り込まれ、この通気フィルタ36を通してガイド部材35の内端部に設けられた通気部28からガイド部材35内に送り込まれるように構成されている。   Further, as shown in FIG. 6, the air passage 27 is formed so that the air outside the watch case 1 when the head 37 of the operation member 11 is pushed out of the main body case 2 by the spring force of the coil spring 25. Is sent into the exterior hole portion 14 through the space between the inner peripheral surface of the exterior hole portion 14 and the outer peripheral surface of the head portion 37, and the fed air is sent to the outer end portion of the guide member 35 and the inner periphery of the exterior case 3. It is fed into the ventilation filter 36 from the plurality of notches 40a of the flange portion 40 through the space between the surfaces, and is fed into the guide member 35 from the ventilation portion 28 provided at the inner end of the guide member 35 through the ventilation filter 36. It is configured to be.

また、このガイド部材35は、第1実施形態と同様、その軸方向の位置が位置規制部によって位置規制されている。すなわち、この位置規制部も、ガイド部材21の内端部が当接する貫通孔10の段差部15と、ガイド部材35のフランジ部40の外端面が当接する外装孔部14の周囲に位置する外装ケース3の内面と、で構成されている。   Further, as in the first embodiment, the position of the guide member 35 in the axial direction is restricted by the position restricting portion. That is, this position restricting portion is also an exterior located around the stepped portion 15 of the through hole 10 with which the inner end portion of the guide member 21 abuts and the exterior hole portion 14 with which the outer end surface of the flange portion 40 of the guide member 35 abuts. And an inner surface of the case 3.

これにより、この位置規制部も、図6および図9に示すように、ガイド部材35の外端部に設けられたフランジ部40が貫通孔10の大径孔部13内に嵌め込まれて、ガイド部材35の内端部が貫通孔10の段差部15に当接し、フランジ部40の外端面が外装孔部14の周囲に位置する外装ケース3の内面に当接することにより、軸方向に移動しないように構成されている。   Thereby, as shown in FIGS. 6 and 9, the position restricting portion is also fitted with the flange portion 40 provided at the outer end portion of the guide member 35 in the large-diameter hole portion 13 of the through hole 10. The inner end portion of the member 35 abuts on the stepped portion 15 of the through hole 10, and the outer end surface of the flange portion 40 abuts on the inner surface of the exterior case 3 positioned around the exterior hole portion 14, so that it does not move in the axial direction. It is configured as follows.

このような腕時計のスイッチ装置34によれば、第1実施形態と同様、防水部材38によってガイド部材35の内周面と操作部材11の頭部37の外周面との間の防水性および気密性を確保することができる共に、通気部28と通気フィルタ36とフランジ部40の複数の切欠き部40aとで構成された通気路27によって、ガイド部材35内の空気と腕時計ケース1の外部の空気とを通気させることができるので、ガイド部材35内の空気圧を腕時計ケース1の外部の気圧とほぼ同じに保つことができる。このため、防水部材38によって防水性および気密性を確保しても、操作部材11の操作性を向上させることができる。   According to such a wristwatch switch device 34, as in the first embodiment, the waterproof member 38 is waterproof and airtight between the inner peripheral surface of the guide member 35 and the outer peripheral surface of the head 37 of the operation member 11 by the waterproof member 38. The air in the guide member 35 and the air outside the watch case 1 can be secured by the air passage 27 formed by the air vent 28, the air filter 36, and the plurality of notches 40a of the flange 40. Therefore, the air pressure in the guide member 35 can be kept substantially the same as the air pressure outside the watch case 1. For this reason, even if waterproofness and airtightness are ensured by the waterproof member 38, the operability of the operation member 11 can be improved.

また、このスイッチ装置34においても、第1実施形態と同様、ガイド部材35内に仮に水などの液体が浸入しても、その浸入した水などの液体を通気フィルタ36の毛細管現象によって腕時計ケース1の外部に排出することができる。このため、ガイド部材35内に水などの液体が溜まることがないので、防錆効果があるほか、操作部材11の操作性を、より一層、確保することができ、これにより操作部材11を良好にかつ円滑に操作させることができる。   Also in the switch device 34, as in the first embodiment, even if a liquid such as water enters the guide member 35, the watch case 1 is caused by the capillary action of the ventilation filter 36 even if the liquid such as water enters the guide member 35. Can be discharged outside. For this reason, since liquids, such as water, do not accumulate in the guide member 35, in addition to having a rust prevention effect, the operability of the operation member 11 can be further ensured. And can be operated smoothly.

この場合、通気部28は、操作部材11の頭部37がガイド部材35内に押し込まれた際に、頭部37の内端部よりも腕時計ケース1の内部側に位置するガイド部材35の箇所、つまりガイド部材35の内端部に設けられていることにより、第1実施形態と同様、操作部材11の頭部37がガイド部材35内をスライドしても、頭部37によって通気部28が塞がれることがない。このため、操作部材11の頭部37のスライド動作に応じて、ガイド部材35内の空気と腕時計ケース1の外部の空気とを確実にかつ良好に通気することができる。   In this case, when the head 37 of the operation member 11 is pushed into the guide member 35, the ventilation portion 28 is located at a position of the guide member 35 located on the inner side of the wristwatch case 1 with respect to the inner end of the head 37. That is, by providing the inner end portion of the guide member 35, even if the head portion 37 of the operation member 11 slides inside the guide member 35, the vent portion 28 is formed by the head portion 37 as in the first embodiment. It will not be blocked. Therefore, the air in the guide member 35 and the air outside the wristwatch case 1 can be reliably and satisfactorily ventilated according to the sliding operation of the head 37 of the operation member 11.

また、このスイッチ装置34では、防水部材38がガイド部材35の内周面に設けられ、かつ操作部材11の頭部37の外周面に圧接した状態で、頭部37の外周面が摺動することにより、第1実施形態と同様、操作部材11のスライド動作に応じて頭部37の外周面が防水部材38に対して移動しても、ガイド部材35の内周面と操作部材11の頭部37の外周面との間の防水性および気密性を確保することができる。   In the switch device 34, the outer peripheral surface of the head 37 slides in a state where the waterproof member 38 is provided on the inner peripheral surface of the guide member 35 and is pressed against the outer peripheral surface of the head 37 of the operation member 11. Thus, as in the first embodiment, even if the outer peripheral surface of the head 37 moves relative to the waterproof member 38 in accordance with the sliding motion of the operation member 11, the inner peripheral surface of the guide member 35 and the head of the operation member 11 Waterproofness and airtightness between the outer peripheral surface of the portion 37 can be ensured.

さらに、このスイッチ装置34では、ガイド部材35の外端部に貫通孔10の大径孔部13に嵌合するフランジ部40が設けられていることにより、ガイド部材35を大径孔部13内に配置した際に、フランジ部40の外周面を大径孔部13の内周面に接触または圧接させた状態で配置することができる。これにより、ガイド部材35の外周面と大径孔部13の内周面との間に円筒状の隙間を形成することができるので、この隙間に通気フィルタ36を確実にかつ良好に配置することができる。   Further, in the switch device 34, the guide member 35 is provided in the large-diameter hole portion 13 by providing the flange portion 40 that fits in the large-diameter hole portion 13 of the through hole 10 at the outer end portion of the guide member 35. When it arrange | positions, it can arrange | position in the state which made the outer peripheral surface of the flange part 40 contact or press-contact the inner peripheral surface of the large diameter hole part 13. FIG. Thereby, since a cylindrical gap can be formed between the outer peripheral surface of the guide member 35 and the inner peripheral surface of the large-diameter hole portion 13, the ventilation filter 36 is reliably and satisfactorily arranged in this gap. Can do.
