特開2006−228545公報
2. Description of the Related Art In a switch structure of an electronic device, a switch structure in which a tactile switch provided on an inner surface of a metal flat plate is operated by providing a slit in a metal flat plate and pressing a portion surrounded by the slit is known. . (Patent Document 1)
JP 2006-228545 A

前述のスリットはプレス加工、エッチング加工、レーザー加工によって形成されることが多く、スリットのエッジ部分は非常に鋭利な状態となっている。したがって、このようなスイッチ機構を採用すると、使用者はその端面が鋭利な部分を押圧することになってしまう。また、押圧される部分は片持ち支持となるので、その端面がなにかに引っかかった場合には、押圧される部分がめくれあがって塑性変形しまうという問題があった。   The slits described above are often formed by pressing, etching, or laser processing, and the edge portion of the slit is in a very sharp state. Therefore, when such a switch mechanism is employed, the user presses a portion having a sharp end surface. In addition, since the pressed portion is cantilevered, there is a problem that when the end surface is caught in something, the pressed portion is turned up and plastically deformed.

本発明は、このようなスイッチ構造を有する電子機器において、安全かつ押圧される部分がめくれあがるという変形を起しにくい電子機器を提供することを目的としている。   An object of the present invention is to provide an electronic device having such a switch structure that is unlikely to be deformed such that a safe and pressed portion is turned up.

本発明の電子機器は、スイッチを有する電子機器であって、押圧部を囲むようにスリットが形成される第1の外装部材と、前記第1の外装部材が貼られる第2の外装部材と、前記スイッチと当接するピン部が形成され、前記第1の外装部材の前記押圧部に貼られる押し子部材と、前記押し子部材を前記第2の外装部材に対して弾性的に支持する弾性部材とを有し、前記弾性部材に前記第1の外装部材の前記スリットから突出するリブ部を形成するとともに、前記押圧部の前記リブ部に対向する端面よりも前記押し子部材の前記リブ部に対向する端面が前記リブに向けて突出するように、前記押し子部材を前記押圧部に貼ることを特徴とする。   The electronic device of the present invention is an electronic device having a switch, a first exterior member in which a slit is formed so as to surround the pressing portion, a second exterior member to which the first exterior member is attached, A pin member that contacts the switch is formed, and a pusher member that is attached to the pressing portion of the first exterior member, and an elastic member that elastically supports the pusher member with respect to the second exterior member A rib portion protruding from the slit of the first exterior member is formed on the elastic member, and the rib portion of the pusher member is positioned closer to the rib portion of the pressing portion than the end surface of the pressing portion facing the rib portion. The pusher member is affixed to the pressing portion such that opposing end surfaces protrude toward the rib.

本発明によれば、安全でありながら押圧部がめくれあがる変形の少ない電子機器を提供することができる。   According to the present invention, it is possible to provide an electronic device that is safe and has little deformation in which the pressing portion is turned up.

図1〜7に基づいて本発明の実施形態であるデジタルカメラのスイッチ構造について説明する。なお、本発明はデジタルカメラに限定されるものではなく、スイッチを備えた電子機器全般に適用可能である。   A switch structure of a digital camera according to an embodiment of the present invention will be described with reference to FIGS. Note that the present invention is not limited to a digital camera, and can be applied to any electronic device having a switch.

図1は本発明の実施形態であるデジタルカメラ10の外観を説明する図である。デジタルカメラ10の背面を外装カバー13(第2の外装部材)が覆う構成になっている。外装カバー13の表面に金属製の化粧板11(第1の外装部材)が貼着される。   FIG. 1 is a view for explaining the appearance of a digital camera 10 according to an embodiment of the present invention. An exterior cover 13 (second exterior member) covers the back surface of the digital camera 10. A metal decorative plate 11 (first exterior member) is attached to the surface of the exterior cover 13.

図2はデジタルカメラ10の要部分解斜視図である。化粧板11は両面テープ14にて外装カバー13に貼られている。図2中の符号11bは化粧板11に形成されたスリットであって、スリット11bにて囲まれる符号11aの領域が押圧部として機能する。押圧部11aは両面テープ14(貼着部材)にて硬質樹脂で形成された押し子部材15に貼られている。弾性部材16によって押し子部材15は外装カバー13に対してに弾性的に支持されている。すなわち、弾性部材16を介して外装カバー13に取り付けられる押し子部材15に押圧部11aが貼られている。そして、デジタルカメラ10の内部にはスイッチ12が配置され、押し子部材15のピン部15bがスイッチ12に当接するように、押し子部材15は外装カバー13に対して位置が決められている。このような構成によって、化粧板11の押圧部11aを外装カバー13に対して押し込むことで、スイッチ12をオンすることができる。   FIG. 2 is an exploded perspective view of the main part of the digital camera 10. The decorative plate 11 is attached to the exterior cover 13 with a double-sided tape 14. Reference numeral 11b in FIG. 2 is a slit formed in the decorative board 11, and a region of reference numeral 11a surrounded by the slit 11b functions as a pressing portion. The pressing part 11a is affixed to a pusher member 15 formed of a hard resin with a double-sided tape 14 (adhering member). The pusher member 15 is elastically supported by the outer cover 13 by the elastic member 16. That is, the pressing portion 11 a is attached to the pusher member 15 that is attached to the exterior cover 13 via the elastic member 16. A switch 12 is disposed inside the digital camera 10, and the position of the pusher member 15 with respect to the exterior cover 13 is determined so that the pin portion 15 b of the pusher member 15 contacts the switch 12. With such a configuration, the switch 12 can be turned on by pressing the pressing portion 11 a of the decorative plate 11 into the exterior cover 13.

図3はデジタルカメラ10のスイッチ構造の拡大図であって、図4は図3のA−A断面図である。図3に示すように、弾性部材16には化粧板11のスリット11bに遊嵌するリブ部16aが形成されている。図4に示すように、リブ部16aは化粧板11の表面から寸法αだけ突出している。したがって、リブ部16aは押圧部11aの端面に向かい合う位置で化粧板11の表面よりも突出しているので、デジタルカメラ10の使用者が押圧部11aの端面に触れるというリスクを少なくすることができる。   3 is an enlarged view of the switch structure of the digital camera 10, and FIG. 4 is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 3, the elastic member 16 is formed with a rib portion 16 a that loosely fits into the slit 11 b of the decorative plate 11. As shown in FIG. 4, the rib portion 16 a protrudes from the surface of the decorative plate 11 by a dimension α. Therefore, since the rib part 16a protrudes rather than the surface of the decorative board 11 in the position facing the end surface of the press part 11a, the risk that the user of the digital camera 10 touches the end surface of the press part 11a can be reduced.

また、図3および4に示すように、押し子部材15の端面15aが押圧部11aの端面よりも寸法βだけリブ部16aに対向する方向に突出するように、押し子部材15は押圧部11aに貼られている。このように構成することで、押圧部11aを押した場合にも、外部から力を加えられてリブ部16aが変形した場合にも、押圧部11aの端面とリブ部16aとが接触することがない。仮にこの寸法βが0に設定されると、押圧部11aを押したときに押圧部11aの端面がリブ部16aに引っかかって押圧感が低下したり、押圧部11aが押されたまま復帰しなくなるという問題がある。これに対して、押し子部材15は表面が滑らかな硬質樹脂で形成されているので、リブ部16aに接触したとしても引っかかることがない。   Further, as shown in FIGS. 3 and 4, the pusher member 15 has a pressing portion 11a so that the end face 15a of the pusher member 15 protrudes in a direction opposite to the rib portion 16a by a dimension β from the end face of the pressing portion 11a. It is affixed to. By configuring in this way, even when the pressing portion 11a is pressed, or when the rib portion 16a is deformed by applying a force from the outside, the end surface of the pressing portion 11a and the rib portion 16a may come into contact with each other. Absent. If the dimension β is set to 0, when the pressing portion 11a is pressed, the end surface of the pressing portion 11a is caught by the rib portion 16a, and the pressing feeling is lowered, or the pressing portion 11a remains pressed and does not return. There is a problem. On the other hand, since the pusher member 15 is formed of a hard resin with a smooth surface, it does not get caught even if it contacts the rib portion 16a.

さらに、弾性部材16は図4に示しように外周部16bが化粧板11に密着しているので、リブ部16aと押し子部材15の端面との隙間から水滴や異物が侵入したとしても、デジタルカメラ10の内部に影響を与える可能性を低くすることができる。   Furthermore, as shown in FIG. 4, the elastic member 16 has an outer peripheral portion 16 b that is in close contact with the decorative plate 11, so that even if water droplets or foreign matter enters from the gap between the rib portion 16 a and the end surface of the pusher member 15, The possibility of affecting the inside of the camera 10 can be reduced.

図5は図3のB−B断面図である。図5に示すように、導光部材17が押し子部材15に接着され、デジタルカメラ10の内部に配置される発光素子20からの光を押圧部11aの表面に導くように構成されている。導光部材17の位置に対応する弾性部材16には穴16cが形成され、発光素子20からの光を遮ることがない。   5 is a cross-sectional view taken along line BB in FIG. As shown in FIG. 5, the light guide member 17 is bonded to the pusher member 15 and is configured to guide light from the light emitting element 20 disposed inside the digital camera 10 to the surface of the pressing portion 11 a. A hole 16 c is formed in the elastic member 16 corresponding to the position of the light guide member 17, and does not block light from the light emitting element 20.

図6は化粧板11を裏面、すなわち両面テープ14が貼られる面から見た図である。符号11cは化粧板11の厚みを部分的に薄くする溝部である。溝部11c、11d、11eを形成することで、化粧板11の板厚が厚くした場合にも押圧部11aを撓みやすくすることができる。一般的にこのような化粧板の板厚を厚くすると押圧部を撓ませるためには大きな力を要するので、操作性が悪くなってしまう。一方、化粧板の板厚を薄くすると簡単に塑性変形を起してしまう。特に爪を立てて押圧部を押されることによって生じる爪傷などが問題になる。   FIG. 6 is a view of the decorative board 11 as seen from the back surface, that is, the surface to which the double-sided tape 14 is applied. Reference numeral 11 c is a groove part that partially reduces the thickness of the decorative plate 11. By forming the groove portions 11c, 11d, and 11e, the pressing portion 11a can be easily bent even when the thickness of the decorative plate 11 is increased. In general, when the thickness of such a decorative plate is increased, a large force is required to bend the pressing portion, resulting in poor operability. On the other hand, if the thickness of the decorative plate is reduced, plastic deformation is easily caused. In particular, there is a problem such as nail scratches caused by raising the nail and pressing the pressing portion.

本実施形態では、溝部11c〜11eの厚みは0.15mmに設定され、化粧板11の厚み0.2mmに対して0.05mmだけ薄くなっている。溝部11cの加工はエッチング処理により加工されている。エッチング処理による加工とすることで、化粧板11の外観面に傷・打痕等の影響が少なく、寸法のばらつきも少ないというメリットがある。   In the present embodiment, the thickness of the grooves 11c to 11e is set to 0.15 mm, and is thinner by 0.05 mm than the thickness of the decorative plate 11 is 0.2 mm. The groove 11c is processed by an etching process. By processing by the etching process, there is an advantage that the appearance of the decorative plate 11 is less affected by scratches and dents and has less dimensional variation.

また、本実施形態では溝部11cの溝幅よりも溝部11dの溝幅が大きい。また、溝部11dの近傍に溝部11eが並んで設けられている。これは化粧板11の外縁部からの距離によって押圧部11aの撓みやすさが異なるからである。それぞれに同一の溝部を設けた場合、化粧板11の外縁部からの距離が短い図6における左側の押圧部11aは、化粧板11の外縁部からの距離が長い図6における右側の押圧部11aよりも撓みやすくなる。   In the present embodiment, the groove width of the groove portion 11d is larger than the groove width of the groove portion 11c. Moreover, the groove part 11e is provided in the vicinity of the groove part 11d. This is because the ease of bending of the pressing portion 11a varies depending on the distance from the outer edge portion of the decorative plate 11. When the same groove portion is provided in each, the left pressing portion 11a in FIG. 6 with a short distance from the outer edge portion of the decorative plate 11 is the right pressing portion 11a in FIG. It becomes easier to bend than.

したがって、押圧部11aの場所によって必要な押圧力などの操作感が変わってしまう。本実施形態では、化粧板11の外縁部からの距離が長い押圧部11aに対応する溝部は、化粧板11の外縁部からの距離が短い押圧部11aに対応する溝部よりも溝の幅や数を増やすことで、同一の操作感を実現している。本実施形態では溝部11c〜11eの深さは均一であるが、押圧部11aの化粧板11の外縁部からの距離が長いほど溝部の深さを深くしても同様の効果を奏することができる。   Therefore, the operational feeling such as the necessary pressing force varies depending on the location of the pressing portion 11a. In the present embodiment, the groove portion corresponding to the pressing portion 11a having a long distance from the outer edge portion of the decorative plate 11 has a groove width and number that are larger than the groove portion corresponding to the pressing portion 11a having a short distance from the outer edge portion of the decorative plate 11. The same feeling of operation is realized by increasing. In this embodiment, although the depth of the groove parts 11c-11e is uniform, even if it makes the depth of a groove part deep, so that the distance from the outer edge part of the decorative board 11 of the press part 11a is long, there can exist the same effect. .

図7は化粧板11に両面テープ14を貼った状態を示している。図7から明らかなように、溝部11cには両面テープ14が貼られ、溝部11d、11eには両面テープ14が貼られていない。したがって、両面テープ14の厚み分だけ押圧部11aの押圧方向の撓み代が確保でき、操作力の差を更に低減させることが可能となる。このように、本実施形態では両面テープ14を貼るか、貼らないかによっても、押圧部11aの操作感を調整している。   FIG. 7 shows a state in which the double-sided tape 14 is pasted on the decorative board 11. As is clear from FIG. 7, the double-sided tape 14 is stuck to the groove 11c, and the double-sided tape 14 is not stuck to the grooves 11d and 11e. Therefore, the bending allowance in the pressing direction of the pressing portion 11a can be secured by the thickness of the double-sided tape 14, and the difference in operating force can be further reduced. Thus, in this embodiment, the operational feeling of the pressing part 11a is adjusted depending on whether the double-sided tape 14 is applied or not.
