図１は、本発明にかかる接触センサの一実施態様を示す図である。１－Ａにおいて、接触センサ１００は、接触による押圧を受けてｏｎ／ｏｆｆ動作するスイッチ１１０を有する回路基板１２０と、スイッチ１１０を押す側には、接触による押圧を受ける押圧受体１３０を有し、押圧受体１３０は、押圧により凹むカバー１３１と、その内側にあって、接触の衝撃を緩和するゲル等の緩和材１３２と、更に、その内側にあって押圧を仲介しスイッチ１１０に伝達する為に、スイッチ１１０に近接した堅い平底面をもった介在体１３３を有し、介在体１３３の平面とは反対側は、凸状面を有し、その形状に倣い、緩和材１３２とカバー１３１の形状が形成されることで、スイッチ１１０を押す等、動作させる方向だけでなく、これとは角度のある斜めの方向、或いは直角な角度の横方向からの押圧にも検出性を向上させたものである。
尚、介在体１３３の凸状面側は、堅さにこだわらないが、堅い平底面を傾斜させるために押圧の伝達を有効にするための堅さは必要である。従って、堅い平底面を含めて介在体１３３は堅い方が好都合である。 FIG. 1 is a diagram showing one embodiment of a contact sensor according to the present invention. In 1-A, the contact sensor 100 has a circuit board 120 having a switch 110 that is turned on/off by receiving pressure due to contact, and a pressure receiver 130 that receives pressure due to contact on the side that presses the switch 110. The pressure receiving body 130 includes a cover 131 which is recessed by pressure, a cushioning material 132 such as gel inside the cover 131 for cushioning the impact of contact, and a cushioning material 132 inside the cover 131 for transmitting the pressure to the switch 110 via an intermediary of the pressure. For this reason, it has an interposer 133 with a rigid flat bottom surface close to the switch 110, and the opposite side of the interposer 133 has a convex surface. By forming the shape of , not only the direction in which the switch 110 is operated, such as pressing the switch 110, but also the oblique direction with an angle, or the lateral direction with an angle at right angles can be detected. It is.
The convex surface side of the intervening body 133 does not need to be rigid, but it needs to be rigid enough to effectively transmit pressure in order to incline the hard flat bottom surface. Therefore, it is advantageous for the interposer 133 to be rigid, including a rigid flat bottom surface.

１－Ｂには、接触センサ１００を棒状基体１４０の先端に取付けた状態であり、棒状基体１４０には、発光表示灯その他の電気回路を搭載したり、衝撃緩衝用のバネ等や、横曲がりをさせる部材を取付けることも可能である。 1-B shows a state in which the contact sensor 100 is attached to the tip of a rod-shaped substrate 140, and the rod-shaped substrate 140 is equipped with a light-emitting indicator lamp and other electric circuits, a shock absorbing spring and the like, and a side bending sensor. It is also possible to attach a member that causes the

１－Ｃには、スイッチ基体１１１に対してスイッチノブ１１２を押圧することで動作するスイッチを示すが、通常のプッシュスイッチが使える他、強い押圧に対して衝突破壊のないように押圧によりスイッチの電極が離間する構造か、又は、スイッチの電極が相互にスライドし、電極の側面で接触する構造のものを使用することが望ましい。前者では、押圧がない時は接触しているが、押圧があると離れるだけで押圧による衝撃は起こらない。後者では、二つの接触導体の接触面が押圧による動きの向きと平行なので、押圧による衝撃は起こらない。尚、スイッチ１１０は、どの方向からの押圧にも対応する等方向性スイッチ(第一）であることが好ましい。そのためには、例えば、スイッチの２つの接触端子が同径且つ同心円の円盤状で近接して平行に離間していて、押圧によって一方の接触端子が傾いた場合には、どの方向からでも、他方の接触端子に接触するようなスイッチを使うことが出来る。又は、通常の等方向性でないスイッチを縦横、又は斜め、又は円周状に複数個配置し、そのどれがスイッチオンになっても動作する回路にすることで、等方向性スイッチ（第一）と同じ作用をさせることができる。即ち、斜め方向又は横方向の押圧で介在体１３３が斜めになり、介在体１３３の堅い平底面が斜めになりスイッチ１１０側にせり出すことで、複数個の内、いずれか１つはスイッチＯＮに押し込まれるからである。 1-C shows a switch that operates by pressing the switch knob 112 against the switch base 111. In addition to using a normal push switch, the switch can be operated by pressing so as not to crash and break against strong pressing. It is desirable to use a design in which the electrodes are spaced apart or in which the electrodes of the switch slide over each other and contact at the sides of the electrodes. In the former case, they are in contact with each other when there is no pressure, but when pressure is applied, they simply separate and no pressure impact occurs. In the latter, no pressure impact occurs since the contact surfaces of the two contact conductors are parallel to the direction of the pressure movement. The switch 110 is preferably an isotropic switch (first) that can be pressed from any direction. For this purpose, for example, when two contact terminals of a switch are disc-shaped with the same diameter and concentric circles and are spaced closely parallel to each other, and one contact terminal is tilted by pressing, the other contact terminal can be moved from any direction. It is possible to use a switch that touches the contact terminals of Alternatively, by arranging a plurality of ordinary non-isotropic switches vertically, horizontally, diagonally, or in a circular shape, and making a circuit that operates even if any of them is switched on, the isotropic switch (first) can have the same effect as That is, the intervening body 133 is obliquely pressed by pressing in an oblique direction or a lateral direction, and the hard flat bottom surface of the intervening body 133 becomes oblique and protrudes toward the switch 110, so that one of the plurality of intervening bodies is turned on. because it will push you in.

尚、１－Ｄー１から１－Ｄ－４を用いて、縦から斜め更には横方向の応力に対応して、スイッチ１１０を押し込む等動作させることが可能なことを詳述する。請求項では、縦方向を、スイッチ１１０を押す等動作させる方向と同じ方向（堅い平底面に直角）、横方向を、スイッチ１１０を押す等動作させる方向と直角な方向（堅い平底面に平行）と表現している。
１－Ｄ－１では、押圧（図の上から下の矢印）が、スイッチを押す等動作させる方向に平行（上記の介在体１３３の堅い平底面に直角）の場合であり、当然、押圧で介在体１３３の堅い平底面が動きスイッチ１１０を動作させる。
１－Ｄ－２では、押圧（図の斜め矢印）が、斜め方向であって、押圧の示す線の延長に介在体１３３の堅い平底面の中心がなくずれがある場合であり、押圧受体１３０は、回路基板１２０側との組み立て結合により、結合部周辺は傾く程度以上には動かない状態であるので、堅い平底面の中心を回転軸として押圧の示す線との距離の長さを回転片（例えば、自転車のペダルの付いた回転中心から伸びたアームに相当）にした回転トルクが押圧によりかかり、回転動作により、押圧受体１３０が、従って、堅い平底面が傾き、下にせり出した方が、スイッチ１１０を動作させる。
１－Ｄー３では、押圧（図の斜め矢印）が、斜め方向であって、押圧の示す線の延長に介在体１３３の堅い平底面の中心がある場合であり、１－Ｄ－２の様な回転トルクはないが、堅い平底面に直角方向の押圧の分力で介在体１３３の堅い平底面が動き、スイッチ１１０を動作させる。
１－Ｄ－４では、押圧（図の横の矢印）が、横（介在体１３３の堅い平底面に平行）方向であって、１－Ｄ－２と同様に、堅い平底面の中心を回転片として堅い平底面と押圧の示す線との距離の長さを回転片にした回転トルクが押圧によりかかり、回転動作により、押圧受体１３０が、従って、堅い平底面が傾き、下にせり出した方が、スイッチ１１０を動作させる。 In addition, using 1-D-1 to 1-D-4, it will be described in detail that the switch 110 can be operated, such as by pushing, in response to vertical, oblique, and horizontal stress. In the claims, the vertical direction is the same direction as the direction of operation such as pressing the switch 110 (perpendicular to the rigid flat bottom surface), and the horizontal direction is the direction perpendicular to the direction of operation such as pressing the switch 110 (parallel to the rigid flat bottom surface). is expressed.
In 1-D-1, the pressing (the arrow from the top to the bottom of the figure) is parallel to the direction of operation such as pressing a switch (perpendicular to the hard flat bottom surface of the above interposed body 133). The rigid flat bottom surface of interposer 133 actuates motion switch 110 .
In 1-D-2, the pressure (diagonal arrow in the figure) is in an oblique direction, and the extension of the line indicated by the pressure does not have the center of the rigid flat bottom surface of the interposed body 133 and there is a deviation, and the pressure receiver 130 is assembled and connected to the circuit board 120 side, so that the periphery of the connecting portion does not move beyond the degree of tilting, so the center of the rigid flat bottom surface is rotated as the rotation axis by the length of the distance from the line indicated by the pressure. A rotating torque applied to a piece (e.g., an arm extending from the center of rotation of a bicycle pedal) is applied by pressing, and the rotating action causes the pressing receiver 130, and thus the rigid flat bottom surface, to tilt and protrude downward. the other causes switch 110 to operate.
In 1-D-3, the pressing (diagonal arrow in the figure) is in an oblique direction, and the extension of the line indicated by the pressing is the center of the rigid flat bottom surface of the interposer 133, and 1-D-2. Although there is no such rotational torque, the hard flat bottom surface of the interposer 133 moves due to the pressing force in the direction perpendicular to the hard flat bottom surface, and the switch 110 is operated.
In 1-D-4, the pressure (horizontal arrow in the figure) is in the lateral direction (parallel to the rigid flat bottom surface of the interposer 133) and rotates around the center of the rigid flat bottom surface as in 1-D-2. Rotational torque is applied by pressing, with the length of the distance between the hard flat bottom surface and the line indicating the pressing force as a piece of rotation, and the rotation motion causes the pressure receiver 130, and therefore the hard flat bottom surface, to tilt and protrude downward. the other causes switch 110 to operate.

１－Ｄー１から１－Ｄ－４のいずれの場合、従って、縦、斜め、横いずれの方向からの応力にも対応してスイッチ１１０が動作可能である。介在体１３３の堅い平底面がスイッチ１１０方向に動く又は介在体１３３の堅い平底面が傾くことによる下へのせり出しによって、スイッチ１１０の動作がなされる。
尚、押圧受体１３０は、回路基板１２０側との組み立て結合により、結合部周辺は傾く程度以上には、動かない状態であることは、どの場合でも同じである。
尚、更に、介在体１３３は、頂点を通り縦に切った断面が、半円形、又は、頂点を長軸側の頂点とする半楕円形、の半球状であることが押圧の応力の伝達に好ましい。しかしながら、半円形や半楕円形にこだわらず、円柱状にすることでも応力の伝達に支障がなく出来る。円柱状の場合には、円柱の長さは、円柱の断面の直径以上であることが好ましい。半円形、半楕円形、円柱状などその組み合わせも可能である。 In any of the cases 1-D-1 to 1-D-4, the switch 110 can operate in response to stress from any of vertical, oblique and horizontal directions. The switch 110 is actuated by the downward protrusion of the rigid flat bottom surface of the interposer 133 either by moving toward the switch 110 or by tilting the rigid flat bottom surface of the interposer 133 .
In any case, the pressure receiving body 130 is in a state where it does not move more than the extent that the periphery of the connecting portion is tilted due to assembly and connection with the circuit board 120 side.
Furthermore, the cross section cut vertically through the apex of the interposer 133 is semi-circular or semi-elliptical with the apex being the apex on the long axis side. preferable. However, the semi-circular or semi-elliptical shape can be used without hindrance to the transmission of the stress by using a columnar shape. In the case of a cylindrical shape, the length of the cylinder is preferably equal to or greater than the diameter of the cross section of the cylinder. Semi-circular, semi-elliptical, cylindrical, and combinations thereof are also possible.

図２は、本発明にかかる接触センサの他の実施態様を示す図であり、幅（横）方向の検出性を向上するためのものである。図１との違いを挙げると、介在体１３３が２つの部分でできていて、一方は、堅い平底面を持った平底面基体１３３Ａ、他方は、凸状面を持った凸状面基体１３３Ｂであり、凸状面基体１３３Ｂの凸状面とは反対側の部分と、平底面基体１３３Ａの平底面とは反対側の部分とが回転嵌め合い構造をしており、凸状面基体１３３Ｂの横方向の移動により、平底面基体１３３Ａが回転して傾き、スイッチ１１０を押す構成にしたもので、幅（横）方向の検出性を向上することが出来る。２－Ｂには、２－Ａの斜視図を示し、回転嵌め合い構造が、球形の凹凸状形状の場合であり、２－Ｃには、回転嵌め合い構造が、円錐の凹凸状形状の場合である。 FIG. 2 is a diagram showing another embodiment of the contact sensor according to the present invention, which is intended to improve detectability in the width (horizontal) direction. The difference from FIG. 1 is that the interposer 133 is made of two parts, one is a flat bottom substrate 133A with a rigid flat bottom and the other is a convex surface substrate 133B with a convex surface.

In FIG. 4, as a further complement to the configuration of FIGS. 1-3, an isotropic switch 410 can be added for operation in response to lateral pressure from either direction.

The isotropic switch 410 can determine pressing by, for example, a change in capacitance between electrodes. The isotropic switch 410 is located at the connection point between the contact sensor 100 and the rod-shaped substrate 140, or any place on the rod-shaped substrate 140 side from the connection point, as indicated by Δ in 4-A, 4-B, and 4-C.

棒状基体１４０は、その軸の周りに回転する回転結合部５１０と棒状基体１４０が前記棒状基体が２分した接続部で回転傾斜する傾斜結合部５２０とを有することで、横からの押圧が来ると、押圧による力を逃がす向きに、即ち、棒状基体１４０が傾斜を可能とする方向に先ず回転結合部５１０で回転し、該接続部を介して棒状基体１４０が傾斜をし、傾斜を検出する傾斜センサ５３０（図示せず）を動作させることで、幅（横）方向の検出性を向上させ、接触センサ１００の動作を補助するものである。回転結合部５１０と傾斜結合部５２０により、横方向のどの方向からの押圧にも対応して、等方向性の動作となる。 FIG. 5 is a diagram showing another embodiment of the contact sensor according to the present invention, which is another example for improving detectability in the width (horizontal) direction.
The rod-shaped base 140 has a rotary coupling portion 510 that rotates around its axis and an inclined coupling portion 520 that rotates and inclines at the joint where the rod-shaped substrate 140 is divided into two parts, so that lateral pressure is applied. Then, the rod-shaped substrate 140 first rotates in the direction in which the pressing force is released, that is, in the direction in which the rod-shaped substrate 140 can be tilted. By operating the tilt sensor 530 (not shown), the detectability in the width (horizontal) direction is improved and the operation of the contact sensor 100 is assisted. The rotary joint 510 and the angled joint 520 provide isotropic motion in response to pressure from any lateral direction.

尚、接触センサに押圧が除かれた場合は、スイッチ１１０を押していない状態に押圧受体１３０、緩和材１３２，カバー１３１の位置が復帰することは当然であり、緩和材１３２，カバー１３１の復元弾性により復帰してもよいし、図示はないが、押圧受体１３０と回路基板１２０間に復元のためのバネ等を付設してもよいことは当然である。 When the pressure is removed from the contact sensor, the positions of the pressure receiver 130, the cushioning member 132 and the cover 131 naturally return to the state in which the switch 110 is not pressed, and the cushioning member 132 and the cover 131 are restored. It may be restored by elasticity, and although not shown, it is a matter of course that a spring or the like may be provided between the pressure receiver 130 and the circuit board 120 for restoration.

尚、等方向性スイッチについては、等方向性スイッチ（第一）と等方向性スイッチ（第二）を区別した表現とした。 The isotropic switch is expressed by distinguishing between the isotropic switch (first) and the isotropic switch (second).

以上のように本発明にかかる接触センサでは、スイッチを押す方向と、その横方向、或いは斜め方向からの押圧に対応し、更に、スイッチへの破壊的過度衝撃を緩和するので、産業上利用して極めて好都合である。 As described above, the contact sensor according to the present invention can be applied to industrial applications because it can respond to the direction in which the switch is pressed, the lateral direction, or the diagonal direction, and furthermore, it can mitigate the destructive excessive impact on the switch. is very convenient.
