Description

【0001】
【発明の属する技術分野】
本発明は、スイッチの操作方向により、操作方向に設けた導電部材が、これに対向する位置に設けられたスイッチパターンと接触することによって、スイッチパターンを導通することでスイッチングする電子機器の多方向スイッチに関するものである。
【0002】
【従来の技術】
従来の多方向スイッチとしては、実開昭58−159132号公報記載のものが知られている。従来の多方向スイッチを図6および図7に示す。図6は従来例の部分透視図であり、図6は図7の断面図である。
図6と図7に示すように、スイッチ操作方向にスイッチパターン3aないし3dを有する基板3と、前記スイッチパターンに対向する位置にそれぞれに導電部2cを設けたゴム製のスイッチドーム部2dがあり、それぞれのスイッチドーム2dに対応して設けられ、スイッチケースの外部から操作可能な操作部2aによってスイッチが構成されている。前記操作部を前記スイッチ操作方向に操作したとき、操作方向に設けた一つの導電部材が、これに対向する位置に設けられた前記スイッチパターンと接触することによって該スイッチパターンを導通するように構成されている。
【0003】
【発明が解決しようとする課題】
しかし、従来の多方向スイッチにおいては、図6と図7に示すように導電部及び操作部が複数で形成されるため、操作部は導電部と対向の位置に複数必要となるため、4方向であれば十字のような形状になり小型化出来ない。
さらに、操部中央部には、支点部材が設けられているため操作部を垂直方向に操作することができない。
【0004】
そこで、この発明の目的は、従来のスイッチの有する上記課題を解決した、小型多方向スイッチを得ることである。
【0005】
【課題を解決するための手段】
上記課題を解決するために本発明は、スイッチケースと、複数のスイッチ操作方向にスイッチパターンを有する基板と、前記スイッチパターンに対向する位置に二つの導電部材を設けたゴム製のスイッチ可動部と、該スイッチ可動部から立設され、スイッチケースの外部から操作可能な操作部とによって構成されるスイッチであって、前記操作部を前記スイッチ操作方向に操作したとき、操作方向に設けた前記導電部材が、これに対向する位置に設けられた前記スイッチパターンと接触することによって該スイッチパターンを導通するような構成とした。
【0006】
この構成においてスイッチ可動部に円周状凸部を設け、操作部を垂直方向に操作したときは、前記円周状凸部の全面を支点に、また操作部をスイッチ操作方向に操作したときは、前記円周状凸部の操作方向側の凸部を支点にしてスイッチ可動部が揺動するようになるので、操作に都合のよい構造を実現できるように多方向スイッチを構成した。
【0007】
【発明の実施の形態】
以下、図面に示す実施例に基づき本発明を具体的に説明する。
図1は、本発明の第一の実施例による多方向スイッチの外観図である。1はスイッチケースで、2aはスイッチケース1の外部から操作するスイッチ操作部である。
【0008】
操作者はこのスイッチ操作部2aを垂直押しあるいは、操作したい方向へ倒すことでスイッチングをする。
図2は、スイッチ導電部とスイッチパターンの部分透視図、また図3は、図1のA−A′線に沿った断面図である。
図4は、図3のスイッチ操作部2aを垂直方向に押した断面図であり、図5は、図3のスイッチ操作部2aをA方向に倒した断面図である。
【0009】
図2と図3と図4と図5において、本発明の第一の実施例を詳細に説明する。スイッチ操作部2aは、プラスチックで成形された部材で、その下部にはゴム製のスイッチ可動部2bが一体に成形されて設けられている。スイッチ可動部2bは、ドーム形状をしており、周辺のドーム部2dと周辺のスイッチ押部2eとからなる。スイッチ押部2eには、導電ゴムを印刷によって形成した導電部材2cとその中央部にも導電ゴムを印刷によって形成した導電部材2gが設けられている。また導電部材2gの外周には、凸部2fが設けられている。
【0010】
基板3には、複数のスイッチ操作方向に対応する位置にスイッチパターン3aないし3eが形成されている。スイッチケース1には、スイッチ可動部2bに設けたドーム部2dを収納するくぼみ部1aが設けられている。このくぼみ部1aにドーム部2dを収納し、さらに基板3をドーム部2dの下において、これをスイッチケース1に固定することで、スイッチとして組み立てられるようになっている。
【0011】
組み立てた状態では、スイッチ押部2eに設けた円周状凸部2fが基板3に接触し、スイッチ操作部2aは、この凸部2fを支点として作動するようになっている。
次に以上のように構成した多方向スイッチの動作について説明する。
図1、図2、図3、図4に示すように、例えばスイッチ操作部2aを垂直方向に押すように動かすと、スイッチ可動部2cのドーム部2dが変形し、さらに円周状凸部2f全面が、押圧されスイッチ押部2eの導電部材2gがスイッチパターン3eと接触し導通する。
【0012】
一方、外周部に設けた導電部材2cは、導電部材2gよりもスイッチパターン面に遠い位置に形設しているためスイッチパターン3aないし3dには接触しない事で垂直方向のスイッチがONしたことになる。
さらに、図1、図2、図3、図5に示すように、例えばスイッチ操作部2aをA方向に倒すように動かすと、スイッチ可動部2bのドーム部2dが屈曲し、さらにスイッチパターン3b近傍にある円周状凸部2fの直線形状部が変形し、スイッチ押部2eの導電部材2cがA方向にあるスイッチパターン3bと接触し導通する。
【0013】
一方、中央部に設けた導電部材2gは、円周状凸部2fの直線形状部を支点に持ち上げられるためスイッチパターン3eには接触しない事でA方向のスイッチがONしたことになる。
このように、スイッチ操作部を垂直押しあるいは、多方向に倒すことで、操作方向にあるスイッチパターンとスイッチの導電部材が接触し導通する事で多方向にスイッチングすることができるようになっている。
【0014】
【発明の効果】
以上説明したように、本発明によれば、電子機器の多方向スイッチ構造において、多方向にあるスイッチパターンを、一つの導電部と操作部によってスイッチングするように構成した。このため小型の垂直方向および多方向スイッチを実現できるようになった。
【0015】
さらに、スイッチ操作部を垂直押した場合は、円周状凸部全面が支点となり、またスイッチ操作部を多方向に倒した場合は、円周状凸部の倒す方向の直線部が支点となるスイッチ構成により安定したスイッチ操作ができる。

As a conventional multi-directional switch, a switch described in Japanese Utility Model Laid-Open No. 58-159132 is known. A conventional multidirectional switch is shown in FIGS. 6 is a partial perspective view of a conventional example, and FIG. 6 is a cross-sectional view of FIG.
As shown in FIGS. 6 and 7, there is a substrate 3 having switch patterns 3a to 3d in the switch operating direction, and a rubber switch dome portion 2d provided with a conductive portion 2c at a position facing the switch pattern. Each switch dome 2d is provided corresponding to each switch dome, and a switch is configured by an operation portion 2a that can be operated from the outside of the switch case. When the operation unit is operated in the switch operation direction, one conductive member provided in the operation direction is brought into conduction by contacting the switch pattern provided at a position facing the conductive member. Has been.
[0003]
[Problems to be solved by the invention]
However, in the conventional multi-directional switch, as shown in FIGS. 6 and 7, a plurality of conductive portions and operation portions are formed, so a plurality of operation portions are required at positions opposite to the conductive portions. Then, it becomes a cross shape and cannot be downsized.
Furthermore, since the fulcrum member is provided in the center part of the control part, the operation part cannot be operated in the vertical direction.
[0004]
Accordingly, an object of the present invention is to obtain a compact multi-directional switch that solves the above-mentioned problems of conventional switches.
[0005]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a switch case, a substrate having a switch pattern in a plurality of switch operating directions, and a rubber switch movable portion provided with two conductive members at positions facing the switch pattern.

The member is configured to conduct the switch pattern by contacting the switch pattern provided at a position facing the member.
[0006]
In this configuration, when the switch movable part is provided with a circumferential convex part and the operation part is operated in the vertical direction, the entire surface of the circumferential convex part is used as a fulcrum, and the operation part is operated in the switch operation direction. Since the switch movable part swings with the convex part on the operation direction side of the circumferential convex part as a fulcrum, a multidirectional switch is configured so as to realize a structure convenient for operation.
[0007]

On the substrate 3, switch patterns 3a to 3e are formed at positions corresponding to a plurality of switch operation directions. The switch case 1 is provided with a recessed portion 1a for accommodating the dome portion 2d provided in the switch movable portion 2b. The dome portion 2d is housed in the indented portion 1a, and the substrate 3 is fixed to the switch case 1 under the dome portion 2d, so that it can be assembled as a switch.
[0011]
In the assembled state, the circumferential convex portion 2f provided on the switch pressing portion 2e comes into contact with the substrate 3, and the switch operation portion 2a operates with the convex portion 2f as a fulcrum.
Next, the operation of the multidirectional switch configured as described above will be described.
As shown in FIGS. 1, 2, 3, and 4, for example, when the switch operating portion 2a is moved so as to be pushed in the vertical direction, the dome portion 2d of the switch movable portion 2c is deformed, and the circumferential convex portion 2f is further deformed. The entire surface is pressed, and the conductive member 2g of the switch pressing portion 2e comes into contact with the switch pattern 3e to conduct.
[0012]
On the other hand, since the conductive member 2c provided on the outer peripheral portion is formed at a position farther from the switch pattern surface than the conductive member 2g, the switch in the vertical direction is turned on by not contacting the switch patterns 3a to 3d. Become.
Further, as shown in FIGS. 1, 2, 3, and 5, for example, when the switch operating portion 2a is moved so as to be tilted in the A direction, the dome portion 2d of the switch movable portion 2b is bent, and further in the vicinity of the switch pattern 3b. The linearly shaped portion of the circumferential convex portion 2f in the shape is deformed, and the conductive member 2c of the switch pressing portion 2e comes into contact with the switch pattern 3b in the A direction to conduct.
[0013]
On the other hand, since the conductive member 2g provided in the central portion can be lifted with the linear shape portion of the circumferential convex portion 2f as a fulcrum, the switch in the A direction is turned on by not contacting the switch pattern 3e.
As described above, when the switch operation unit is vertically pressed or tilted in multiple directions, the switch pattern in the operation direction and the conductive member of the switch come into contact with each other and are switched to enable switching in multiple directions. .
[0014]
【The invention's effect】
As described above, according to the present invention, in the multi-directional switch structure of the electronic device, the switch pattern in the multi-direction is configured to be switched by one conductive unit and the operation unit. For this reason, small vertical and multidirectional switches can be realized.
[0015]
Furthermore, when the switch operation part is pushed vertically, the entire circumferential convex part becomes a fulcrum, and when the switch operation part is tilted in multiple directions, the linear part in the direction in which the circumferential convex part is tilted becomes a fulcrum. Stable switch operation is possible with the switch configuration.
