Description

本発明は、スイッチ装置の耐衝撃構造、電子機器及び時計に関するものである。 The present invention relates to an impact resistant structure for a switch device, an electronic device, and a timepiece.

従来、時計等の電子機器において、本体ケースに竜頭等の操作部材が引き出し可能に設けられたスイッチ装置を備えたものが知られている。
このようなスイッチ装置では、操作部材の軸部にモジュールと連結された巻真等の軸部材が取り付けられており、ケースから外部に突出した操作部材を引き出して操作部材を回転させることにより、時刻の修正等を行うことができるように構成されている。
しかし、モジュールと連結されている軸部材はかなり細いものであることから、時計等の電子機器に外部から衝撃が加えられた際に、軸部材が曲がったり折れたりしやすいとの問題がある。
特に、時計等の電子機器が竜頭等の操作部材の側から落下する等により衝撃を受けると、操作部材に受けた衝撃が、操作部材とモジュールとを繋いでいる軸部材によってモジュールに伝えられる。この結果、モジュールが破損したり、軸部材とモジュールとが衝突して、軸部材及びモジュールの双方又は一方が破損するおそれもある。 2. Description of the Related Art Conventionally, an electronic device such as a watch is known that includes a switch device in which an operation member such as a crown can be pulled out from a main body case.
In such a switch device, a shaft member such as a winding stem connected to the module is attached to the shaft portion of the operation member, and the operation member is pulled out from the case and rotated to rotate the operation member. It is comprised so that correction | amendment etc. can be performed.
However, since the shaft member connected to the module is quite thin, there is a problem that the shaft member is likely to be bent or broken when an external impact is applied to an electronic device such as a watch.
In particular, when an electronic device such as a watch receives an impact, for example, when it falls from the side of an operation member such as a crown, the impact received by the operation member is transmitted to the module by a shaft member connecting the operation member and the module. As a result, the module may be damaged, or the shaft member and the module may collide, and both or one of the shaft member and the module may be damaged.

このため、竜頭等の操作部材及びこれに連結される巻真等の軸部材を保護するためにプロテクタを設けることが提案されている。
例えば、特許文献１には、竜頭がロックされている際には竜頭の頭部を取り囲むように周囲に配置された保護位置をとり得、竜頭を操作する際には竜頭の頭部を露出させるように退避する退避位置をとり得るように構成された保護枠部を備えたプロテクタを設けることが開示されている。 For this reason, it has been proposed to provide a protector to protect the operation member such as the crown and the shaft member such as the winding stem connected thereto.
For example, in Patent Document 1, when the crown is locked, a protection position arranged around the crown head can be taken, and when the crown is operated, the crown head is exposed. Thus, it is disclosed to provide a protector including a protective frame portion configured to be able to take a retracted position.

しかしながら、竜頭等の操作部材の周囲にプロテクタを設けただけでは外部から衝撃が加えられた際の巻真等の軸部材とモジュールとの衝突を防ぐことはできず、軸部材とモジュールとの衝突による軸部材等の破損を回避することはできない。
また、竜頭等の操作部材の周囲にプロテクタを設けると、ケースが大型化するとともに、時計等の電子機器の外観デザインに著しい制約が生じてしまうという問題もある。 However, simply installing a protector around the operation member such as the crown cannot prevent the shaft member such as the winding stem from colliding with the module when an impact is applied from the outside. It is impossible to avoid damage to the shaft member or the like due to the above.
In addition, when a protector is provided around an operation member such as a crown, there is a problem that the case becomes large and the external design of an electronic device such as a watch is significantly restricted.

本発明は以上のような事情に鑑みてなされたものであり、外観デザインへの影響が少なく、かつ軸部材とモジュールとの衝突による軸部材の損傷等を効果的に防ぐことのできるスイッチ装置の耐衝撃構造、電子機器及び時計を提供することを目的とするものである。 The present invention has been made in view of the above circumstances, and is a switch device that has little influence on the external appearance design and can effectively prevent damage to the shaft member due to collision between the shaft member and the module. An object is to provide an impact resistant structure, an electronic device, and a watch.

図７は、抜け止め部材とその周辺を拡大した要部斜視図である。なお、図７では抜け止め部材８の構成を示すために、筒状部材７及び中枠部材３の図示を省略している。
図６及び図７等に示すように、抜け止め部材８は、本体ケース１とモジュール２との間に配置され、筒状部材７が本体ケース１の貫通孔１０から抜けることを防止するものである。
図４及び図６等に示すように、抜け止め部材８における本体ケース１に対向する側の面には後述する第１の緩衝部材４４が当接しており、抜け止め部材８における中枠部材３及びモジュール２に対向する側の面には中枠部材３の衝撃伝達部３２が当接している。 FIG. 7 is a perspective view of an essential part in which a retaining member and its periphery are enlarged. In FIG. 7, the cylindrical member 7 and the middle frame member 3 are not shown in order to show the configuration of the retaining member 8.
As shown in FIGS. 6 and 7, the retaining member 8 is disposed between the main body case 1 and the module 2, and prevents the tubular member 7 from coming out of the through hole 10 of the main body case 1. is there.
As shown in FIGS. 4 and 6, a first buffer member 44 described later is in contact with the surface of the retaining member 8 facing the main body case 1, and the middle frame member 3 in the retaining member 8. The impact transmitting portion 32 of the middle frame member 3 is in contact with the surface facing the module 2.

本実施形態における抜け止め部材８は、例えば硬質の合成樹脂又は金属材料等で形成された板状の部材である。抜け止め部材８には、一端側に開口を有する係止用切欠き部８１が形成されている。
本実施形態では、抜け止め部材８は筒状部材７の軸方向に直交して時計１００における裏面側から表面側に向かって筒状部材７の係止用細軸部７３に嵌め込まれるようになっており、係止用切欠き部８１は、組み立て時において時計１００の視認側に配置される側に開口している。
抜け止め部材８の係止用切欠き部８１は、筒状部材７の小径筒部７ａにおける係止用細軸部７３の外径よりも大きな幅を有するとともに、開口部近傍に係止用細軸部７３の外径よりも小さな幅に形成されたくびれ部８１ａを有している。
これにより、筒状部材７の係止用細軸部７３が一旦くびれ部８１ａを乗り越えて係止用切欠き部８１の奥まで嵌め込まれると、係止用細軸部７３が抜け止め部材８に係止されて容易に外れない構成となっている。 The retaining member 8 in the present embodiment is a plate-like member formed of, for example, a hard synthetic resin or a metal material. The retaining member 8 is formed with a locking notch 81 having an opening on one end side.
In the present embodiment, the retaining member 8 is fitted into the locking thin shaft portion 73 of the tubular member 7 from the back surface side to the front surface side of the timepiece 100 perpendicular to the axial direction of the tubular member 7. The locking notch 81 is open to the side arranged on the viewing side of the timepiece 100 during assembly.
The locking notch portion 81 of the retaining member 8 has a width larger than the outer diameter of the locking thin shaft portion 73 in the small-diameter cylindrical portion 7a of the cylindrical member 7, and the locking thin portion 81 in the vicinity of the opening. It has a constricted portion 81 a formed with a width smaller than the outer diameter of the shaft portion 73.
As a result, once the locking thin shaft portion 73 of the tubular member 7 gets over the constricted portion 81 a and is fitted to the depth of the locking notch portion 81, the locking thin shaft portion 73 is attached to the retaining member 8. It is configured to be locked and not easily removed.

本実施形態において、筒状部材７は本体ケース１の貫通孔１０内を巻真５の軸線方向に沿って摺動可能となっている。
すなわち、本実施形態では、本体ケース１と抜け止め部材８との間に、弾性変形可能な第１の緩衝部材４４が設けられている。
このため、筒状部材７は、第１の緩衝部材４４が変形する範囲内において移動可能であり、外部から衝撃が加えられた際に、モジュール２が振動したり巻真５の軸方向に移動した場合に、この動きに追従して抜け止め部材８とともに移動する。 In the present embodiment, the cylindrical member 7 is slidable in the through hole 10 of the main body case 1 along the axial direction of the winding stem 5.
That is, in the present embodiment, the first buffer member 44 that is elastically deformable is provided between the main body case 1 and the retaining member 8.
For this reason, the cylindrical member 7 is movable within a range in which the first buffer member 44 is deformed, and the module 2 vibrates or moves in the axial direction of the winding stem 5 when an impact is applied from the outside. In this case, it moves with the retaining member 8 following this movement.

第１の緩衝部材４４は、例えばシリコーンやゴム、ウレタン樹脂等の材料で形成されている。
なお、第１の緩衝部材４４は、弾性変形可能なものであればよく、第１の緩衝部材４４を形成する材料は、上記に例示したものに限定されない。
本実施形態では、時計１００における３時側に対応する位置であって、貫通孔１０に挿通されている筒状部材７の両側に２つの第１の緩衝部材４４が配置されている。
なお、第１の緩衝部材４４が設けられる位置や数、大きさ、厚み、形状等は特に限定されず、時計１００の大きさや形状等に応じて適宜設定される。 The first buffer member 44 is made of a material such as silicone, rubber, or urethane resin.
The first buffer member 44 only needs to be elastically deformable, and the material forming the first buffer member 44 is not limited to those exemplified above.
In the present embodiment, two first buffer members 44 are arranged on both sides of the cylindrical member 7 inserted through the through hole 10 at a position corresponding to the 3 o'clock side of the timepiece 100.
Note that the position, number, size, thickness, shape, and the like of the first buffer member 44 are not particularly limited, and are appropriately set according to the size, shape, and the like of the timepiece 100.

本体ケース１における抜け止め部材８に対向する位置には、第１の緩衝部材４４の変形量を規制する変形規制部１６が設けられている。
本実施形態において変形規制部１６は、本体ケース１の内側に形成された２つの凸部である。
変形規制部１６は、時計１００に外部から衝撃が加えられて第１の緩衝部材４４が押し潰されるように弾性変形した場合に、抜け止め部材８に突き当たることで第１の緩衝部材４４の変形量を規制し、これによって筒状部材７の移動量を規制する。
変形規制部１６が設けられていることにより、例えば、第１の緩衝部材４４として変形量の大きな厚みの厚いものを用いた場合でも、実際には第１の緩衝部材４４はこの変形規制部１６が抜け止め部材８の本体ケース１側の面に突き当たる位置までしか変形しない。
時計１００に外部から強い衝撃が加えられた場合に筒状部材７が大きく移動しすぎるとかえって筒状部材７の内部に挿通されている巻真５や周囲に配置された構成部を損傷するおそれがあるが、変形規制部１６を設けることで筒状部材７の移動量を一定範囲に抑え、筒状部材７が移動しすぎることで生じる弊害を防止することができる。
なお、筒状部材７のモジュール２側（すなわち本体ケース１の内側）への移動は竜頭本体６１が本体ケース１の外側面に突き当てられることで一定範囲に規制されるため、変形規制部１６が設けられていることによって主として規制されるのは、本体ケース１の外側に向かう筒状部材７の移動である。
なお、変形規制部１６は本発明の必須の要素ではない。第１の緩衝部材４４の大きさや硬さ、配置等を工夫することで第１の緩衝部材４４の変形量を一定の範囲内となるように設定することができる場合には変形規制部１６を設けなくてもよい。 A deformation restricting portion 16 that restricts the amount of deformation of the first buffer member 44 is provided at a position facing the retaining member 8 in the main body case 1.
In the present embodiment, the deformation restricting portion 16 is two convex portions formed inside the main body case 1.
When the impact is applied to the timepiece 100 from the outside and the first buffer member 44 is elastically deformed so that the first buffer member 44 is crushed, the deformation restricting portion 16 abuts against the retaining member 8 to deform the first buffer member 44. The amount is regulated, and thereby the amount of movement of the cylindrical member 7 is regulated.
By providing the deformation restricting portion 16, for example, even when a thick material having a large deformation amount is used as the first buffer member 44, the first buffer member 44 actually has the deformation restricting portion 16. Is deformed only to a position where it comes into contact with the surface of the body case 1 side of the retaining member 8.
When a strong impact is applied to the timepiece 100 from the outside, if the tubular member 7 moves too much, the winding stem 5 inserted into the tubular member 7 and the components disposed around it may be damaged. However, by providing the deformation restricting portion 16, it is possible to suppress the movement amount of the cylindrical member 7 within a certain range, and to prevent the adverse effect caused by the excessive movement of the cylindrical member 7.
Note that the movement of the cylindrical member 7 toward the module 2 (that is, the inside of the main body case 1) is restricted to a certain range by the crown main body 61 being abutted against the outer surface of the main body case 1, and therefore, the deformation restricting portion 16 It is the movement of the cylindrical member 7 toward the outer side of the main body case 1 that is mainly regulated by the provision of.
In addition, the deformation | transformation control part 16 is not an essential element of this invention. If the deformation amount of the first buffer member 44 can be set within a certain range by devising the size, hardness, arrangement, etc. of the first buffer member 44, the deformation restricting portion 16 is provided. It does not have to be provided.

また、本体ケース１とモジュール２との間であって、筒状部材７が設けられる位置の本体ケース１における点対称位置及びその近傍位置の少なくともいずれかには、弾性変形可能な第２の緩衝部材４５が配置されている。
第２の緩衝部材４５は、第１の緩衝部材４４と同様に、例えばシリコーンやゴム、ウレタン樹脂等で形成されている。
図８は、時計の９時側の内部を拡大して時計における裏面側から見た要部斜視図である。
本実施形態では、図８に示すように、第１の緩衝部材４４が設けられている時計の３時側の位置の本体ケース１における点対称位置である時計の９時側に対応する位置に第２の緩衝部材４５が配置されている。
図２等に示すように、第１の緩衝部材４４及び第２の緩衝部材４５は、巻真５の軸線方向に沿ってほぼ一直線上に配置されることが好ましい。第１の緩衝部材４４及び第２の緩衝部材４５をこのように配置することにより、時計１００に対して外部から巻真５の軸線方向に向かう衝撃が加えられた際に第１の緩衝部材４４及び第２の緩衝部材４５が互いに適宜弾性変形することで効果的に衝撃を吸収することができる。
なお、第２の緩衝部材４５が設けられる位置や数、大きさ、厚み、形状等は特に限定されず、時計１００の大きさや形状等に応じて適宜設定される。 Further, a second buffer capable of elastic deformation is provided between at least one of the point-symmetrical position and the vicinity thereof in the main body case 1 between the main body case 1 and the module 2 at the position where the cylindrical member 7 is provided. A member 45 is arranged.
Similar to the first buffer member 44, the second buffer member 45 is formed of, for example, silicone, rubber, urethane resin, or the like.
FIG. 8 is an enlarged perspective view of the main part, as viewed from the back side of the timepiece, with the inside of the timepiece 9 o'clock side enlarged.
In the present embodiment, as shown in FIG. 8, the position corresponding to the 9 o'clock side of the timepiece, which is a point-symmetrical position in the main body case 1, at the 3 o'clock side position of the timepiece provided with the first buffer member 44. A second buffer member 45 is disposed.
As shown in FIG. 2 and the like, it is preferable that the first buffer member 44 and the second buffer member 45 are arranged substantially in a straight line along the axial direction of the winding stem 5. By disposing the first buffer member 44 and the second buffer member 45 in this manner, the first buffer member 44 is applied to the timepiece 100 when an impact is applied from the outside toward the axial direction of the winding stem 5. In addition, the second shock absorbing member 45 can be elastically deformed appropriately to absorb the impact effectively.
Note that the position, number, size, thickness, shape, and the like of the second buffer member 45 are not particularly limited, and are appropriately set according to the size, shape, and the like of the timepiece 100.

次に、本実施形態におけるスイッチ装置４の耐衝撃構造及びこれを適用した電子機器としての時計１００の作用について説明する。
本実施形態において、スイッチ装置４を組み立てる際には、竜頭６に連結された巻真５を筒状部材７内に挿通させ、筒状部材７の大径筒部７ｃにパッキン等を介して竜頭６を取り付ける。そして、巻真５及び竜頭６を組み付けた筒状部材７の小径筒部７ａ及び中径筒部７ｂを本体ケース１の外側から内側に向かって挿通させ、本体ケース１の内部に突出した巻真５の一端部（軸本体５１の側）をモジュール２と接続する。
また、時計１００における裏面側から、筒状部材７の係止用細軸部７３を抜け止め部材８に嵌め込むとともに、本体ケース１とモジュール２との間に、時計１００における裏面側から中枠部材３を嵌め込む。
さらに、本体ケース１と抜け止め部材８との間に第１の緩衝部材４４を配置し、筒状部材７が設けられる位置の本体ケース１における点対称位置やその近傍位置に第２の緩衝部材４５を配置する。
これにより、時計１００の外部から衝撃が加えられた際にもその衝撃を効率的に吸収する耐衝撃構造を備えるスイッチ装置４が完成する。
そして、モジュール２等、時計１００の各構成部を内部に収容した本体ケース１の裏面側にパッキン１２ａを介して裏蓋１２を取り付けることで本体ケース１の裏面側の開口を閉塞する。また、本体ケース１の表面側にパッキン１１ａを介して風防ガラス１１を取り付けることで本体ケース１の表面側の開口を閉塞する。これにより、時計１００が完成する。
時計１００に対して外部から衝撃が加えられることでモジュール２が動いた場合には、第１の緩衝部材４４及び第２の緩衝部材４５が弾性変形して衝撃を吸収する。また、巻真５を保持する筒状部材７がモジュール２の動きに追従して移動することで、巻真５やこれと接続されているモジュール２の破損を回避する。
また、第１の緩衝部材４４が押し潰されるように弾性変形すると、本体ケース１と中枠部材３との距離が接近するが、変形規制部１６が抜け止め部材８に突き当てられるとそれ以上は第１の緩衝部材４４が変形せず、筒状部材７が過度に移動することが防止される。 Next, the impact resistant structure of the switch device 4 in this embodiment and the operation of the timepiece 100 as an electronic apparatus to which the shock resistant structure is applied will be described.
In this embodiment, when assembling the switch device 4, the winding stem 5 connected to the crown 6 is inserted into the cylindrical member 7, and the crown is inserted into the large-diameter cylindrical portion 7 c of the cylindrical member 7 via packing or the like. 6 is attached. Then, the small diameter cylindrical portion 7a and the medium diameter cylindrical portion 7b of the cylindrical member 7 assembled with the winding stem 5 and the crown 6 are inserted from the outside to the inside of the main body case 1 so as to protrude into the main body case 1. 5 is connected to the module 2 at one end (the shaft body 51 side).
Further, the locking thin shaft portion 73 of the cylindrical member 7 is fitted into the retaining member 8 from the back surface side of the timepiece 100, and the middle frame from the back surface side of the timepiece 100 is interposed between the main body case 1 and the module 2. The member 3 is fitted.
Further, the first buffer member 44 is disposed between the main body case 1 and the retaining member 8, and the second buffer member is located at a point-symmetrical position in the main body case 1 at a position where the cylindrical member 7 is provided or in the vicinity thereof. 45 is arranged.
As a result, the switch device 4 having an impact-resistant structure that efficiently absorbs an impact even when an impact is applied from the outside of the timepiece 100 is completed.
And the opening of the back surface side of the main body case 1 is obstruct | occluded by attaching the back cover 12 via the packing 12a to the back surface side of the main body case 1 which accommodated each component of the timepiece 100, such as the module 2. FIG. Further, the windshield glass 11 is attached to the front surface side of the main body case 1 via the packing 11 a to close the opening on the front surface side of the main body case 1. Thereby, the timepiece 100 is completed.
When the module 2 is moved by applying an impact to the timepiece 100 from the outside, the first buffer member 44 and the second buffer member 45 are elastically deformed to absorb the impact. Moreover, the cylindrical member 7 holding the winding stem 5 moves following the movement of the module 2, thereby avoiding damage to the winding stem 5 and the module 2 connected thereto.
When the first buffer member 44 is elastically deformed so as to be crushed, the distance between the main body case 1 and the inner frame member 3 approaches, but when the deformation restricting portion 16 is abutted against the retaining member 8, the distance is further increased. The first buffer member 44 is not deformed, and the cylindrical member 7 is prevented from excessively moving.

以上のように、本実施形態によれば、スイッチ装置４は、一端側がモジュール２に回転自在に取り付けられる軸部材である巻真５と、この巻真５の他端側に取り付けられる操作部材である竜頭６と、本体ケース１の貫通孔１０に挿入されるとともに、巻真５が内部に挿通され、当該巻真５を回転自在に保持する筒状部材７と、本体ケース１とモジュール２との間に配置され、筒状部材７が本体ケース１の貫通孔１０から抜けることを防止する抜け止め部材８と、本体ケース１と抜け止め部材８との間に配置され、弾性変形可能な第１の緩衝部材４４と、本体ケース１とモジュール２との間であって、筒状部材７が設けられる位置の本体ケース１における点対称位置及びその近傍位置の少なくともいずれかに配置され、弾性変形可能な第２の緩衝部材４５とを備える耐衝撃構造をとっている。
これにより、衝撃を受けることでモジュール２が動いた場合に、巻真５を保持する筒状部材７がモジュール２の動きに追従して移動することができ、巻真５や筒状部材７が本体ケース１側に固定された状態となっている場合と比較して、巻真５が曲がったり折れたりしにくく、また、巻真５とモジュール２とが衝突するのを防いで、巻真５及びモジュール２の双方又は一方が破損するのを防止することができる。
また、本実施形態では、筒状部材７が設けられる位置の本体ケース１におけるほぼ点対称位置に第２の緩衝部材４５を設けているため、第１の緩衝部材４４及び第２の緩衝部材４５が、巻真５の軸線方向に沿ってほぼ一直線上に配置される。特に、腕時計においては、６時方向及び１２時方向には時計バンド（本実施形態では図示せず）が取り付けられているため、６時方向や１２時方向から衝撃が加わっても時計バンドやその取付部分において衝撃を吸収することができる。これに対し、時計１００に対して巻真５の軸線方向（すなわち、時計における３時方向や９時方向）から衝撃が加えられた場合には、竜頭６や巻真５に、より直接的に衝撃が加わり、巻真５やモジュール２の破損を生じやすい。この点、本実施形態では、第１の緩衝部材４４及び第２の緩衝部材４５を筒状部材７が設けられている時計１００の３時方向とこのほぼ点対称位置である９時方向とに配置することにより、時計１００の３時方向及び９時方向から加えられた衝撃を効果的に吸収して巻真５やモジュール２の破損を防止することができる。
また、本実施形態におけるスイッチ装置４の耐衝撃構造を採用した場合には、本体ケース１の外側にプロテクタ等を設けて衝撃を緩和させる場合と異なり、時計１００が大型化しない。また、外観デザインにも影響を与えないため、デザイン性に優れた時計１００を実現することができる。
また、本体ケース１における抜け止め部材８に対向する位置に、第１の緩衝部材４４の変形量を規制する変形規制部１６が設けられている。このため、第１の緩衝部材４４の変形量、すなわち筒状部材７の移動量を所定の範囲内に抑えることができ、筒状部材７が移動しすぎることによる巻真５やモジュール２等への悪影響を抑えることができる。また、このような変形規制部１６を設けることにより、第１の緩衝部材４４として厚みの厚いものや変形量の大きなものを用いることが可能となり、より高い衝撃吸収効果を期待することができる。
さらに、本実施形態では、モジュール２と第１の緩衝部材４４との間に介在し、第１の緩衝部材４４に対し衝撃を伝達する衝撃伝達部３２を設けている。これにより、外部から加えられた衝撃をピンポイントに集中的に第１の緩衝部材４４に伝えることができ、より高い衝撃吸収効果を期待することができる。 As described above, according to the present embodiment, the switch device 4 includes the winding stem 5 that is a shaft member that is rotatably attached to the module 2 at one end side, and the operation member that is attached to the other end side of the winding stem 5. A crown 6, a cylindrical member 7 that is inserted into the through hole 10 of the main body case 1, and the winding stem 5 is inserted therein, and rotatably holds the winding stem 5, the main body case 1, and the module 2 Between the main body case 1 and the retaining member 8 and elastically deformable. The retaining member 8 prevents the cylindrical member 7 from coming out of the through hole 10 of the main body case 1. 1 is disposed between at least one of the point-symmetrical position in the main body case 1 and the vicinity thereof between the buffer member 44 and the main body case 1 and the module 2 at the position where the cylindrical member 7 is provided. Possible second loose Taking impact structure and a member 45.
Thereby, when the module 2 moves by receiving an impact, the cylindrical member 7 holding the winding stem 5 can move following the movement of the module 2, and the winding stem 5 and the cylindrical member 7 can be moved. Compared to the case where the winding stem 5 is fixed to the main body case 1 side, the winding stem 5 is less likely to be bent or broken, and the winding stem 5 and the module 2 are prevented from colliding with each other. And it is possible to prevent both or one of the modules 2 from being damaged.
In the present embodiment, since the second buffer member 45 is provided at a substantially point-symmetrical position in the main body case 1 at the position where the cylindrical member 7 is provided, the first buffer member 44 and the second buffer member 45 are provided. Are arranged on a substantially straight line along the axial direction of the winding stem 5. In particular, in a wristwatch, a watch band (not shown in the present embodiment) is attached at 6 o'clock and 12 o'clock, so even if an impact is applied from the 6 o'clock or 12 o'clock direction, Shock can be absorbed at the mounting portion. On the other hand, when an impact is applied to the timepiece 100 from the axial direction of the winding stem 5 (that is, 3 o'clock direction or 9 o'clock direction in the timepiece), the crown 6 or winding stem 5 is more directly applied. An impact is applied and the winding stem 5 and the module 2 are easily damaged. In this respect, in the present embodiment, the first buffer member 44 and the second buffer member 45 are arranged in the 3 o'clock direction of the timepiece 100 on which the cylindrical member 7 is provided and the 9 o'clock direction which is a substantially point-symmetrical position. By disposing, the impact applied from the 3 o'clock direction and 9 o'clock direction of the timepiece 100 can be effectively absorbed to prevent the winding stem 5 and the module 2 from being damaged.
In addition, when the impact resistant structure of the switch device 4 in the present embodiment is adopted, the timepiece 100 does not increase in size unlike the case where a protector or the like is provided outside the main body case 1 to reduce the impact. In addition, since the appearance design is not affected, the timepiece 100 having excellent design can be realized.
Further, a deformation restricting portion 16 that restricts the deformation amount of the first buffer member 44 is provided at a position facing the retaining member 8 in the main body case 1. For this reason, the deformation amount of the first buffer member 44, that is, the movement amount of the cylindrical member 7 can be suppressed within a predetermined range, and the winding stem 5 or the module 2 due to the excessive movement of the cylindrical member 7 can be obtained. The adverse effect of can be suppressed. Further, by providing such a deformation restricting portion 16, it is possible to use a thick member or a large deformation member as the first buffer member 44, and a higher impact absorbing effect can be expected.
Further, in the present embodiment, an impact transmission portion 32 that is interposed between the module 2 and the first buffer member 44 and transmits an impact to the first buffer member 44 is provided. Thereby, the impact applied from the outside can be intensively transmitted to the first buffer member 44 in a pinpoint manner, and a higher impact absorbing effect can be expected.

［第２の実施形態］
次に、図９から図１１を参照しつつ、本発明に係るスイッチ装置の耐衝撃構造、電子機器及び時計の第２の実施形態について説明する。なお、本実施形態でもスイッチ装置の耐衝撃構造が適用される電気機器が時計である場合を例とする。また、本実施形態は、モジュール及び筒状部材の構成のみが第１の実施形態と異なるものであるため、以下においては、特に第１の実施形態と異なる点について説明する。 [Second Embodiment]
Next, a second embodiment of the shock-resistant structure of the switch device, the electronic device, and the timepiece according to the present invention will be described with reference to FIGS. In the present embodiment as well, the case where the electrical device to which the impact resistance structure of the switch device is applied is a watch is taken as an example. In addition, since the present embodiment is different from the first embodiment only in the configuration of the module and the cylindrical member, in the following, differences from the first embodiment will be particularly described.

図９は、本実施形態に係る時計の３時側の内部を時計における裏面側から見た要部平面図であり、図１０は、図９におけるX-X線に沿って本実施形態に係る時計を断面にした場合の要部側断面図である。
図９及び図１０に示すように、本実施形態では、筒状部材７における本体ケース１の内部に突出する側の端部がモジュール２に係止されている。これにより、衝撃を受けてモジュール２が動いた場合には、筒状部材７及びこれに保持されている巻真５がモジュール２の動きに追従してモジュール２とともに移動するようになっている。 FIG. 9 is a plan view of the main part of the interior of the timepiece according to the present embodiment viewed from the back side of the timepiece, and FIG. 10 shows the timepiece according to the present embodiment along the line XX in FIG. It is principal part side sectional drawing at the time of making it a cross section.
As shown in FIGS. 9 and 10, in this embodiment, the end of the cylindrical member 7 on the side protruding into the main body case 1 is locked to the module 2. As a result, when the module 2 is moved in response to an impact, the cylindrical member 7 and the winding stem 5 held by the tubular member 7 follow the movement of the module 2 and move together with the module 2.

図１１は、モジュール２における筒状部材７の係止部分を拡大した要部斜視図である。
図１１に示すように、本実施形態において、モジュール２における筒状部材７に対応する位置（本実施形態では、時計における３時側）には、筒状部材７における本体ケース１への挿入側端部を係止する係止部としての係止用フック２２が設けられている。
係止用フック２２は、筒状部材７の側に張り出すとともに端部が下方（図１０等における下方向）に向かってほぼＬ字状に屈曲する下向きの係止用フック２２ａと、筒状部材７の側に張り出すとともに端部が上方（図１０等における上方向）に向かってほぼＬ字状に屈曲する上向きの係止用フック２２ｂとからなる。
筒状部材７における本体ケース１への挿入側端部（すなわち、本体ケース１の内部に突出する側の端部）には、筒状部材７の外周面に沿って係止溝部７４が形成されており、モジュール２の係止用フック２２ａ，２２ｂは、筒状部材７の上下方向（図１０等における上下方向）からこの係止溝部７４を挟み込むように係止する。これにより、筒状部材７はモジュール２に連結され、モジュール２の動きに追従するように構成される。
なお、係止部は、モジュール２が筒状部材７を係止可能なものであればよく、ここで例示した構成に限定されない。 FIG. 11 is an enlarged perspective view of a main part of the module 2 where the locking portion of the tubular member 7 is enlarged.
As shown in FIG. 11, in this embodiment, the cylindrical member 7 is inserted into the main body case 1 at a position corresponding to the cylindrical member 7 in the module 2 (in this embodiment, 3 o'clock side in the timepiece). A locking hook 22 is provided as a locking portion for locking the end.
The locking hook 22 projects downward toward the tubular member 7 and has an end portion bent downwardly (downward in FIG. 10 and the like) and bent downward in a substantially L shape. An upward locking hook 22b that protrudes toward the member 7 and bends in an almost L shape toward the upper side (upward in FIG. 10 and the like).
A locking groove 74 is formed along the outer peripheral surface of the cylindrical member 7 at the end of the cylindrical member 7 on the insertion side to the main body case 1 (that is, the end on the side protruding into the main body case 1). The locking hooks 22a and 22b of the module 2 are locked so as to sandwich the locking groove 74 from the vertical direction of the cylindrical member 7 (vertical direction in FIG. 10 and the like). Thereby, the cylindrical member 7 is connected to the module 2 and is configured to follow the movement of the module 2.
In addition, the latching part should just be a thing in which the module 2 can latch the cylindrical member 7, and is not limited to the structure illustrated here.

なお、その他の構成は、第１の実施形態と同様であることから、同一部材には同一の符号を付して、その説明を省略する。 In addition, since the other structure is the same as that of 1st Embodiment, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted.

次に、本実施形態におけるスイッチ装置４の耐衝撃構造及びこれを適用した電子機器としての時計１００の作用について説明する。
まず、第１の実施形態と同様に、スイッチ装置４を組み立てる際には、竜頭６に連結された巻真５を筒状部材７内に挿通させ、筒状部材７の大径筒部７ｃにパッキン等を介して竜頭６を取り付ける。そして、巻真５及び竜頭６を組み付けた筒状部材７の小径筒部７ａ及び中径筒部７ｂを本体ケース１の外側から内側に向かって挿通させる。さらに、筒状部材７の係止溝部７４にモジュール２の係止用フック２２を係止させ、この状態で本体ケース１の内部に突出した巻真５の一端部（軸本体５１の端部）をモジュール２と接続する。
時計１００に対して外部から衝撃が加えられることでモジュール２が動いた場合には、第１の緩衝部材４４及び第２の緩衝部材４５が弾性変形して衝撃を吸収する。また、モジュール２の一端に係止された筒状部材７及びこれに保持される巻真５がモジュール２の動きに追従して移動することで、巻真５やこれと接続されているモジュール２の破損を回避する。 Next, the impact resistant structure of the switch device 4 in this embodiment and the operation of the timepiece 100 as an electronic apparatus to which the shock resistant structure is applied will be described.
First, similarly to the first embodiment, when assembling the switch device 4, the winding stem 5 connected to the crown 6 is inserted into the cylindrical member 7, and the large-diameter cylindrical portion 7 c of the cylindrical member 7 is inserted. The crown 6 is attached through packing or the like. Then, the small-diameter cylindrical portion 7 a and the medium-diameter cylindrical portion 7 b of the cylindrical member 7 assembled with the winding stem 5 and the crown 6 are inserted from the outside of the main body case 1 toward the inside. Further, the locking hook 22 of the module 2 is locked in the locking groove 74 of the cylindrical member 7, and in this state, one end of the winding stem 5 that protrudes into the main body case 1 (the end of the shaft main body 51). Is connected to module 2.
When the module 2 is moved by applying an impact to the timepiece 100 from the outside, the first buffer member 44 and the second buffer member 45 are elastically deformed to absorb the impact. Further, the tubular member 7 locked to one end of the module 2 and the winding stem 5 held by the cylindrical member 7 follow the movement of the module 2 to move the winding stem 5 and the module 2 connected thereto. To avoid damage.

なお、その他の点については、第１の実施形態と同様であることから、その説明を省略する。 Since other points are the same as those in the first embodiment, description thereof is omitted.

以上のように、本実施形態によれば、第１の実施形態と同様の効果を得られる他、以下の効果を得ることができる。
すなわち、本実施形態では、モジュール２の係止用フック２２ａ，２２ｂが筒状部材７の係止溝部７４に係止されることにより、筒状部材７がモジュール２と直接的に連結される。このため、時計１００に対して外部から衝撃が加えられることでモジュール２が動いた場合には、筒状部材７がより確実にモジュール２の動きに追従し、モジュール２と巻真５との衝突を回避して、モジュール２や巻真５が損傷するのを防止することができる。 As described above, according to the present embodiment, the following effects can be obtained in addition to the same effects as those of the first embodiment.
That is, in this embodiment, the hooks 22 a and 22 b for locking the module 2 are locked to the locking grooves 74 of the cylindrical member 7, so that the cylindrical member 7 is directly connected to the module 2. For this reason, when the module 2 moves due to an external impact applied to the timepiece 100, the cylindrical member 7 more reliably follows the movement of the module 2, and the module 2 and the winding stem 5 collide. Thus, the module 2 and the winding stem 5 can be prevented from being damaged.

［第３の実施形態］
次に、図１２から図１４を参照しつつ、本発明に係るスイッチ装置の耐衝撃構造、電子機器及び時計の第２の実施形態について説明する。なお、本実施形態でもスイッチ装置の耐衝撃構造が適用される電気機器が時計である場合を例とする。また、本実施形態は、筒状部材の抜け落ちを防止する抜け止め部材の構成等が第１の実施形態等と異なるものであるため、以下においては、特に第１の実施形態等と異なる点について説明する。 [Third Embodiment]
Next, a second embodiment of the shock-resistant structure of the switch device, the electronic device, and the timepiece according to the present invention will be described with reference to FIGS. In the present embodiment as well, the case where the electrical device to which the impact resistance structure of the switch device is applied is a watch is taken as an example. In addition, since the present embodiment is different from the first embodiment in the configuration of the retaining member that prevents the tubular member from falling off, in the following, particularly the differences from the first embodiment and the like. explain.

図１２は、本実施形態に係る時計の３時側の内部を時計における裏面側から見た要部斜視図であり、図１３は、本実施形態に係る時計の３時側を断面にした場合の要部側断面図である。また、図１４は、中枠部材３及び筒状部材７を拡大した要部斜視図である。 FIG. 12 is a perspective view of an essential part of the interior of the timepiece according to the present embodiment viewed from the back side of the timepiece, and FIG. 13 is a cross-sectional view of the timepiece according to the present embodiment at 3 o'clock. FIG. FIG. 14 is an enlarged perspective view of the main part of the middle frame member 3 and the cylindrical member 7.

図１２から図１４に示すように、本実施形態において、中枠部材３における筒状部材７に対応する部分には、係止用切欠き部３３ａを有する抜け止め部３３が設けられている。
図１３に示すように、筒状部材７における本体ケース１への挿入側端部には、他の部分よりも径の細い係止用細軸部７５が形成されている。
中枠部材３の抜け止め部３３は、筒状部材７の軸方向に直交して時計１００における裏面側から表面側に向かって筒状部材７の係止用細軸部７５に嵌め込まれるようになっており、係止用切欠き部３３ａは、組み立て時において時計１００の視認側に配置される側に開口している。
抜け止め部３３の係止用切欠き部３３ａは、筒状部材７の小径筒部７ａの外径よりも小さな幅であり、係止用細軸部７５の外径よりも大きな幅を有するように形成されている。
これにより、時計１００における裏面側から表面側に向かって中枠部材３を嵌め込み、筒状部材７の係止用細軸部７５が中枠部材３の係止用切欠き部３３ａに係止されると、軸方向（筒状部材７及びこれに挿通されている巻真５の軸方向）への筒状部材７の移動が規制され、筒状部材７の抜け落ちが防止される。
このように、本実施形態では、筒状部材７の係止用細軸部７５が、中枠部材３の抜け止め部３３に係止されるようになっており、中枠部材３の抜け止め部３３が筒状部材７の抜け落ちを防止する抜け止め部材として機能する。
なお、中枠部材３の抜け止め部３３及び係止用切欠き部３３ａの形状等は、ここに例示したものに限定されない。 As shown in FIGS. 12 to 14, in the present embodiment, a retaining portion 33 having a notch portion 33 a for locking is provided at a portion corresponding to the cylindrical member 7 in the middle frame member 3.
As shown in FIG. 13, a locking thin shaft portion 75 having a diameter smaller than that of the other portion is formed at the end of the cylindrical member 7 on the insertion side to the main body case 1.
The retaining portion 33 of the middle frame member 3 is fitted into the locking thin shaft portion 75 of the tubular member 7 from the back surface side to the front surface side of the timepiece 100 perpendicular to the axial direction of the tubular member 7. The locking notch 33a is open on the side arranged on the viewing side of the timepiece 100 during assembly.
The locking notch 33 a of the retaining portion 33 has a width smaller than the outer diameter of the small-diameter cylindrical portion 7 a of the cylindrical member 7 and has a width larger than the outer diameter of the locking thin shaft portion 75. Is formed.
Thereby, the middle frame member 3 is fitted from the back surface side to the front surface side in the timepiece 100, and the locking thin shaft portion 75 of the cylindrical member 7 is locked to the locking notch portion 33 a of the middle frame member 3. Then, the movement of the cylindrical member 7 in the axial direction (the axial direction of the cylindrical member 7 and the winding stem 5 inserted through the cylindrical member 7) is restricted, and the cylindrical member 7 is prevented from falling off.
As described above, in this embodiment, the locking thin shaft portion 75 of the tubular member 7 is locked to the retaining portion 33 of the middle frame member 3, and the retaining member 33 of the middle frame member 3 is prevented. The portion 33 functions as a retaining member that prevents the tubular member 7 from falling off.
In addition, the shape etc. of the retaining part 33 and the notch part 33a for latching of the middle frame member 3 are not limited to what was illustrated here.

また、図１２に示すように、中枠部材３の抜け止め部３３において、変形規制部１６に対向する位置には、それぞれ突き当て部３４が設けられている。
突き当て部３４は、第１の緩衝部材４４が衝撃によって弾性変形した際に、変形規制部１６に突き当てられて、変形規制部１６とともに第１の緩衝部材４４の変形量を規制する。すなわち、本実施形態の第１の緩衝部材４４は、変形規制部１６が突き当て部３４に突き当てられる位置までしか変形せず、第１の緩衝部材４４が過度に変形することにより筒状部材７が移動しすぎることを防止する。 Further, as shown in FIG. 12, in the retaining portion 33 of the middle frame member 3, abutting portions 34 are respectively provided at positions facing the deformation restricting portion 16.
The abutting portion 34 is abutted against the deformation restricting portion 16 when the first buffer member 44 is elastically deformed by an impact, and restricts the deformation amount of the first buffer member 44 together with the deformation restricting portion 16. That is, the first buffer member 44 of the present embodiment is deformed only to the position where the deformation restricting portion 16 is abutted against the abutting portion 34, and the first buffer member 44 is excessively deformed to form a tubular member. 7 is prevented from moving too much.

なお、その他の構成は、第１の実施形態等と同様であることから、同一部材には同一の符号を付して、その説明を省略する。 In addition, since the other structure is the same as that of 1st Embodiment etc., the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted.

次に、本実施形態におけるスイッチ装置４の耐衝撃構造及びこれを適用した電子機器としての時計１００の作用について説明する。
まず、第１の実施形態等と同様に、スイッチ装置４を組み立てる際には、竜頭６に連結された巻真５を筒状部材７内に挿通させ、筒状部材７の大径筒部７ｃにパッキン等を介して竜頭６を取り付ける。そして、巻真５及び竜頭６を組み付けた筒状部材７の小径筒部７ａ及び中径筒部７ｂを本体ケース１の外側から内側に向かって挿通させ、本体ケース１の内部に突出した巻真５の一端部（軸本体５１の側）をモジュール２と接続する。
また、時計１００における裏面側から、中枠部材３を嵌め込む。このとき、中枠部材３の抜け止め部３３の係止用切欠き部３３ａに、筒状部材７の係止用細軸部７５が嵌め込まれるようにする。これにより、筒状部材７が中枠部材３の抜け止め部３３に係止され、本体ケース１の貫通孔１０からの抜け落ちが防止される。
時計１００に対して外部から衝撃が加えられることでモジュール２が動いた場合には、第１の緩衝部材４４及び第２の緩衝部材４５が弾性変形して衝撃を吸収する。また、巻真５を保持する筒状部材７がモジュール２の動きに追従して移動することで、巻真５やこれと接続されているモジュール２の破損を回避する。
また、第１の緩衝部材４４が押し潰されるように弾性変形すると、本体ケース１と中枠部材３との距離が接近するが、変形規制部１６が突き当て部３４に突き当てられるとそれ以上は第１の緩衝部材４４が変形せず、筒状部材７が過度に移動することが防止される。 Next, the impact resistant structure of the switch device 4 in this embodiment and the operation of the timepiece 100 as an electronic apparatus to which the shock resistant structure is applied will be described.
First, similarly to the first embodiment, when assembling the switch device 4, the winding stem 5 connected to the crown 6 is inserted into the cylindrical member 7, and the large-diameter cylindrical portion 7 c of the cylindrical member 7 is inserted. Attach the crown 6 to the top with a packing or the like. Then, the small diameter cylindrical portion 7a and the medium diameter cylindrical portion 7b of the cylindrical member 7 assembled with the winding stem 5 and the crown 6 are inserted from the outside to the inside of the main body case 1 so as to protrude into the main body case 1. 5 is connected to the module 2 at one end (the shaft body 51 side).
Further, the middle frame member 3 is fitted from the back side of the timepiece 100. At this time, the locking thin shaft portion 75 of the tubular member 7 is fitted into the locking notch 33 a of the retaining portion 33 of the middle frame member 3. Thereby, the cylindrical member 7 is latched by the retaining portion 33 of the middle frame member 3, and the falling off from the through hole 10 of the main body case 1 is prevented.
When the module 2 is moved by applying an impact to the timepiece 100 from the outside, the first buffer member 44 and the second buffer member 45 are elastically deformed to absorb the impact. Moreover, the cylindrical member 7 holding the winding stem 5 moves following the movement of the module 2, thereby avoiding damage to the winding stem 5 and the module 2 connected thereto.
Further, when the first buffer member 44 is elastically deformed so as to be crushed, the distance between the main body case 1 and the middle frame member 3 approaches, but when the deformation restricting portion 16 is abutted against the abutting portion 34, the distance is further increased. The first buffer member 44 is not deformed, and the cylindrical member 7 is prevented from excessively moving.

なお、その他の点については、第１の実施形態等と同様であることから、その説明を省略する。 Since other points are the same as those in the first embodiment, the description thereof will be omitted.

以上のように、本実施形態によれば、第１の実施形態等と同様の効果を得られる他、以下の効果を得ることができる。
すなわち、本実施形態では、中枠部材３に抜け止め部３３を設けて、これを抜け止め部材として機能させている。このため、第１の実施形態等のように、抜け止め部材を別途設ける必要がない。これにより、部品点数が少なくて済み、構成を単純化することができるため、組み立て工数の削減、生産コストの低減を実現することができる。 As described above, according to this embodiment, the same effects as those of the first embodiment can be obtained, and the following effects can be obtained.
That is, in the present embodiment, the middle frame member 3 is provided with the retaining portion 33 and functions as a retaining member. For this reason, it is not necessary to separately provide a retaining member as in the first embodiment. Thereby, since the number of parts can be reduced and the configuration can be simplified, it is possible to reduce the number of assembly steps and the production cost.

なお、以上本発明の実施形態について説明したが、本発明は、かかる実施形態に限定されず、その要旨を逸脱しない範囲で、種々変形が可能であることは言うまでもない。 Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and various modifications can be made without departing from the scope of the present invention.

例えば、上記各実施形態では、時計１００における３時側に第１の緩衝部材４４が配置され、９時側に第２の緩衝部材４５が配置されている場合を例示したが、緩衝部材の設けられる位置は時計１００における３時側及び９時側に限定されない。
例えば、図１５に示すように、本体ケース１とモジュール２との間であって、第１の緩衝部材４４及び第２の緩衝部材４５の配置箇所とは異なる部分に、弾性変形可能な第３の緩衝部材４６が設けられていてもよい。
第３の緩衝部材４６は、第１の緩衝部材４４及び第２の緩衝部材４５と同様に、例えばシリコーンやゴム、ウレタン樹脂等で形成される。
この場合、第３の緩衝部材４６は、第１の緩衝部材４４と第２の緩衝部材４５との間を繋ぐような一繋がりの長尺なものであってもよいし、小さな緩衝部材を複数並べて配置してもよい。
第３の緩衝部材４６を設ける位置や範囲、数、形状等は、図示例に限定されない。
このように、時計１００における３時側と９時側に配置される第１の緩衝部材４４及び第２の緩衝部材４５とは別に、本体ケース１とモジュール２との間を埋めるように第３の緩衝部材４６を配置した場合には、時計１００における３時・９時方向（すなわち、巻真５の軸方向）からの衝撃のみならず、時計１００に対するいかなる方向からの衝撃も緩衝部材（第１の緩衝部材４４、第２の緩衝部材４５及び第３の緩衝部材４６）によって吸収することが可能となる。
そして、衝撃によってモジュール２が様々な方向に移動した場合でも、巻真５を保持する筒状部材７が本体ケース１に固定されず、ある程度モジュール２の動きに追従して移動可能に構成されていることにより、巻真５の折れ等の破損が発生しにくく、また、巻真５とモジュール２とが衝突することによるモジュール等の破損も回避することができる。 For example, in each of the above embodiments, the case where the first buffer member 44 is arranged at 3 o'clock side and the second buffer member 45 is arranged at 9 o'clock side in the timepiece 100 is illustrated. The positions to be placed are not limited to the 3 o'clock side and the 9 o'clock side of the timepiece 100.
For example, as shown in FIG. 15, the third elastically deformable third portion is provided between the main body case 1 and the module 2 and in a portion different from the arrangement location of the first buffer member 44 and the second buffer member 45. The buffer member 46 may be provided.
Similar to the first buffer member 44 and the second buffer member 45, the third buffer member 46 is formed of, for example, silicone, rubber, urethane resin, or the like.
In this case, the third buffer member 46 may be a long one that connects between the first buffer member 44 and the second buffer member 45, or a plurality of small buffer members. They may be arranged side by side.
The position, range, number, shape, and the like of the third buffer member 46 are not limited to the illustrated example.
Thus, apart from the first buffer member 44 and the second buffer member 45 arranged at the 3 o'clock side and the 9 o'clock side in the timepiece 100, the third case so as to fill the space between the main body case 1 and the module 2. When the shock absorbing member 46 is disposed, not only the impact from the 3 o'clock and 9 o'clock directions (that is, the axial direction of the winding stem 5) of the timepiece 100 but also the shock from any direction on the timepiece 100 is 1 buffer member 44, second buffer member 45 and third buffer member 46).
Even when the module 2 moves in various directions due to an impact, the cylindrical member 7 that holds the winding stem 5 is not fixed to the main body case 1 and is configured to move to follow the movement of the module 2 to some extent. As a result, damage such as bending of the winding stem 5 is unlikely to occur, and damage to the module or the like due to collision between the winding stem 5 and the module 2 can be avoided.

また、上記各実施形態では、スイッチ装置４の耐衝撃構造が時計１００に適用された場合を例示したが、スイッチ装置４の耐衝撃構造は時計に適用される場合に限定されない。
