It relates to sensors.

従来、この種のリードスイッチ方式の剛体球検出用センサには、特許文献１で開示されたものがある。この例は、図１５に分解斜視図で示すように、蓋部のケース体２ａと底部のケース体２ｂの一端に遊技球１の通過を検出するための検出孔３を設け、この検出孔３の壁部５にリードスイッチ８を配置し、リードスイッチ８側から見て、検出孔３を挟んで左右に対向する検出孔壁内に、長手方向に同磁力に着磁したそれぞれ長さが異なる２本の磁石９ａ，９ｂをリードスイッチ８に対して異磁極で同磁力の磁界が到達するように配置し、且つ、検出孔３を挟んでリードスイッチ８と対向する位置に有する前記２本の磁石９ａ，９ｂの両端間に密着させた金属板（ヨーク）１０を配置することにより、リードスイッチ８の接点片は吸引し合って接点を閉じ、リードスイッチ８の両端に接続された電子回路の出力側に有する負荷回路の出力レベルがＨレベルとなり、検出孔３内を遊技球１が通過すると、遊技球１によってリードスイッチ８に到達している磁界が遮られ、リードスイッチ８が接点を開くことにより、負荷回路の出力レベルがＬレベルとなって遊技球を検出する構造の遊技球検出器が開示されている。なお、４は電子回路などの収設部、５は検出孔３と収設部４を仕切る収設部壁、１１は電子回路基板、１７はコネクタ、１８はプラス電源接続端子、１９は負荷接続端子である（以下、図１５に示す遊技球検出器を従来例１と呼ぶ）。   Conventionally, this type of reed switch type rigid sphere detection sensor is disclosed in Patent Document 1. In this example, as shown in an exploded perspective view in FIG. 15, a detection hole 3 for detecting the passage of the game ball 1 is provided at one end of the case body 2 a at the lid and the case body 2 b at the bottom. The reed switch 8 is disposed on the wall portion 5 of the lead switch 8 and the lengths of the reed switch 8 magnetized with the same magnetic force in the longitudinal direction are different in the detection hole wall opposed to the left and right across the detection hole 3 when viewed from the reed switch 8 side. The two magnets 9a and 9b are arranged so that the magnetic field of the same magnetic force with different magnetic poles can reach the reed switch 8, and the two magnets 9a and 9b are opposed to the reed switch 8 with the detection hole 3 interposed therebetween. By arranging a metal plate (yoke) 10 in close contact between both ends of the magnets 9a and 9b, the contact pieces of the reed switch 8 attract each other and close the contacts, and the electronic circuit connected to both ends of the reed switch 8 The output level of the load circuit on the output side is When the game ball 1 passes through the detection hole 3, the magnetic field reaching the reed switch 8 is blocked by the game ball 1, and the reed switch 8 opens the contact, so that the output level of the load circuit is L level. Thus, a game ball detector having a structure for detecting a game ball is disclosed. In addition, 4 is an accommodating part for an electronic circuit, 5 is an accommodating part wall for partitioning the detection hole 3 and the accommodating part 4, 11 is an electronic circuit board, 17 is a connector, 18 is a positive power connection terminal, 19 is a load connection (Hereinafter, the game ball detector shown in FIG. 15 is referred to as Conventional Example 1).

In this case, the length of the magnet to be combined is changed individually. Since it is necessary, there is a problem that the lead time for obtaining the magnet becomes longer, the cost of parts becomes higher, and the degree of freedom in design becomes smaller.

First, when there is no game ball 23 in the through hole 27 of FIG. 3A, two magnetic fields of different magnetic poles from the magnets 33a and 33b reach both ends of the reed switch 31, and the contact of the reed switch 31 is the magnet 33a. , 33b, so that they are attracted to each other and the contacts are closed (turned on).

次に、図３（ｂ）の貫通孔２７内を遊技球２３が通過している場合の検出動作は、遊技球２３によって磁気回路は、磁石３３ａ、遊技球２３、磁石３３ｂ、磁性金属体３５からなる閉磁路を構成するため、リードスイッチ３１に到達している磁界は著しく減少してリードスイッチ３１は接点を開く（ＯＦＦする）。   Next, the detection operation when the game ball 23 passes through the through hole 27 of FIG. 3B is the magnetic circuit by the game ball 23, the magnet 33 a, the game ball 23, the magnet 33 b, and the magnetic metal body 35. Therefore, the magnetic field reaching the reed switch 31 is significantly reduced and the reed switch 31 opens (turns off) the contact.

ここで本発明の実施の形態１に戻り説明を続ける。図２（ａ）、図２（ｂ）の剛体球検出用センサ２１，４３では、ケース体２５に遊技球２３の通過を検出するための貫通孔２７を設け、この貫通孔２７の周辺部を形成する壁部２９にリードスイッチ３１を配置し、リードスイッチ３１に対して直角方向で、貫通孔２７を挟んで左右に、互いに対向する貫通孔壁内に、長手方向に同一磁界で着磁した同一形状かつ磁化方向長さが同じ２本の磁石３３ａ，３３ｂをリードスイッチ３１の両端に向けて配置し、磁束を引き出し、リードスイッチ３１の一方の端と磁石間の距離Ｌ１に対し、他方の端と磁石間の距離Ｌ２が異なるように配置する。図２では、２つの磁性金属体３５，４５の形状を異ならせることで、磁極端（Ｎ極またはＳ極）とリードスイッチ外部端子の距離を変化させることが出来る様子を示した。   Here, the description will be continued returning to the first embodiment of the present invention. In the rigid ball detection sensors 21 and 43 shown in FIGS. 2A and 2B, a through hole 27 for detecting the passage of the game ball 23 is provided in the case body 25, and a peripheral portion of the through hole 27 is provided. The reed switch 31 is disposed on the wall 29 to be formed, and is magnetized with the same magnetic field in the longitudinal direction in the through hole walls facing each other in the direction perpendicular to the reed switch 31 with the through hole 27 interposed therebetween. Two magnets 33a and 33b having the same shape and the same magnetization direction length are arranged toward both ends of the reed switch 31, the magnetic flux is drawn, and the distance L1 between one end of the reed switch 31 and the magnet is opposite to the other. It arrange | positions so that the distance L2 between an end and a magnet may differ. FIG. 2 shows that the distance between the magnetic pole tip (N pole or S pole) and the reed switch external terminal can be changed by making the shapes of the two magnetic metal bodies 35 and 45 different.

これにより、リードスイッチの両端に到達する磁界の各々の差は、各々の距離の２乗に反比例し、極めて大きな差となるために、遊技球が通過しない場合、各々の接点は異磁極に磁化され吸引（ＯＮ）しているものの、バランスが悪く、各々の接点が同一磁力で吸引している場合に比べ、吸引を解きやすい状態となり、貫通孔内を遊技球が通過すると、遊技球に磁束が吸引され、リードスイッチに到達する磁界が減少するため、ＯＦＦ状態になる構造となっている。   As a result, each difference in the magnetic field reaching both ends of the reed switch is inversely proportional to the square of each distance and is extremely large. Therefore, when the game ball does not pass, each contact is magnetized to a different magnetic pole. Although it is attracted (ON), the balance is poor, and it becomes easier to release the suction than when each contact is attracted with the same magnetic force, and when the game ball passes through the through hole, the magnetic flux is applied to the game ball. Is attracted and the magnetic field reaching the reed switch is reduced, so that it is in an OFF state.

一般に、磁性金属体（例えば軟鉄）は磁石に比べ加工が容易であり、その精度も高い。従って、本実施の形態１の剛体球検出用センサ２１，４３の検出精度が向上し、適合するリードスイッチの感動値範囲も広がり、安定した量産性を確保することが出来る。   In general, a magnetic metal body (for example, soft iron) is easier to process than a magnet and has high accuracy. Therefore, the detection accuracy of the hard sphere detection sensors 21 and 43 according to the first embodiment is improved, the moving value range of the suitable reed switch is expanded, and stable mass productivity can be secured.

図４、図５は本発明の請求項３、請求項４に係る、実施の形態２の剛体球検出用センサを示し、図４（ａ）、図４（ｂ）、図５（ａ）、図５（ｂ）は、磁石と磁性金属体のそれぞれの組み合わせによる剛体球検出用センサの平面図である。   4 and 5 show the hard sphere detection sensor of the second embodiment according to claims 3 and 4 of the present invention, and FIG. 4 (a), FIG. 4 (b), FIG. 5 (a), FIG. 5B is a plan view of a hard sphere detection sensor using a combination of a magnet and a magnetic metal body.

図４、図５を参照して、本実施の形態２は、実施の形態１と略同じ構成を含むので、実施の形態１と同構成の部分は、実施の形態１と同じ参照番号を付して、その説明を省略し、構成の異なる部分についてのみ説明する。   Referring to FIGS. 4 and 5, the second embodiment includes substantially the same configuration as that of the first embodiment. Therefore, the same reference numerals as those of the first embodiment are assigned to the same components as those of the first embodiment. Thus, the description thereof will be omitted, and only different parts will be described.

図４、図５のように、本実施の形態２の剛体球検出用センサ５１，５５，５９，６３は、長手方向に着磁された１本の磁石３３をリードスイッチ３１に対して直角方向に配置し、この磁石３３のリードスイッチ３１とは逆側の端面に磁性金属体５３，５７，６１，６５（ヨーク）を密着させ配置し、且つ、磁性金属体５３，５７，６１，６５は、リードスイッチ３１と対向する位置から磁石３３と対向する位置まで貫通孔２７を囲んで配置されるようになっている。   As shown in FIGS. 4 and 5, the rigid sphere detection sensors 51, 55, 59, and 63 according to the second embodiment are configured such that one magnet 33 magnetized in the longitudinal direction is perpendicular to the reed switch 31.

従って、本実施の形態２の剛体球検出用センサ５１，５５，５９，６３は、磁石が１本であるため部品コストが安くなり、磁性金属体の寸法を変えることで、図４（ａ）を例として説明すると、リードスイッチ３１の両端の一方の端と磁石３３との距離Ｌ３に比べ、他方の端と磁性金属体５３の下端部との距離Ｌ４が異なるように配置することは容易であり、本発明の実施の形態１の剛体球検出用センサと同等の検出精度を確保することが出来る。また、磁性金属体５３のリードスイッチ３１に対向する端面の磁束密度は、磁石３３のリードスイッチ３１に対向する端面（Ｎ極）の磁束密度よりもやや小さくなっているということもある。   Therefore, the hard sphere detection sensors 51, 55, 59, and 63 of the second embodiment have a single magnet, so that the cost of parts is reduced, and the size of the magnetic metal body is changed, so that FIG. As an example, it is easy to arrange so that the distance L4 between the other end and the lower end of the magnetic metal body 53 is different from the distance L3 between one end of the reed switch 31 and the magnet 33. Yes, it is possible to ensure detection accuracy equivalent to that of the hard sphere detection sensor according to the first embodiment of the present invention. In addition, the magnetic flux density of the end surface of the magnetic metal body 53 facing the reed switch 31 may be slightly smaller than the magnetic flux density of the end surface (N pole) of the magnet 33 facing the reed switch 31.

In addition to the magnetic metal body 69 (yoke), magnetic metal bodies 71a and 71b, which are in close contact with the external terminals at both ends of the reed switch 31, are attached to the end surfaces of the two magnets 33a and 33b on the reed switch 31 side.

The detection accuracy equivalent to that of the hard sphere detection sensor according to the first embodiment can be ensured.

図１１は本発明の請求項１２に係る実施の形態８の剛体球検出用センサを示し、図１１（ａ）は平面図、図１１（ｂ）は他の平面図である。   11A and 11B show a rigid sphere detection sensor according to an eighth embodiment of the present invention. FIG. 11A is a plan view and FIG. 11B is another plan view.

図１１を参照して、本実施の形態８は、実施の形態１と略同じ構成を含むので、実施の形態１と同構成の部分は、実施の形態１と同じ参照番号を付して、その説明を省略し、構成の異なる部分についてのみ説明する。   Referring to FIG. 11, the eighth embodiment includes substantially the same configuration as that of the first embodiment. Therefore, the same reference numerals as those in the first embodiment are assigned to the same components as those in the first embodiment. A description thereof will be omitted, and only different parts will be described.

図１１（ａ）を参照して、本実施の形態８の剛体球検出用センサ９７では、円周方向に着磁され、半分ずつ互いに逆方向に磁化されたリング磁石９９が配置されるようになっている。また、リードスイッチ３１は貫通孔２７と同心の円周に接するように配置されている。   Referring to FIG. 11 (a), in rigid sphere detection sensor 97 of the eighth embodiment, ring magnets 99 that are magnetized in the circumferential direction and magnetized in half in opposite directions are arranged.

A ring magnet 99 magnetized in a concentric circumferential direction and magnetized in half in opposite directions is disposed.

このように、本実施の形態８の剛体球検出用センサ９７，１０１は、磁性金属体を配置せずにリング磁石だけであるため部品コストが安くなり、また、実施の形態１の剛体球検出用センサと同等の検出精度を確保することが出来る。   As described above, since the hard sphere detection sensors 97 and 101 of the eighth embodiment are only the ring magnet without arranging the magnetic metal body, the component cost is reduced, and the hard sphere detection of the first embodiment is also performed. Detection accuracy equivalent to that of the sensor for use can be ensured.

図１２は本発明の請求項１３に係る実施の形態９の剛体球検出用センサを示す平面図である。   FIG. 12 is a plan view showing a rigid sphere detection sensor according to a ninth embodiment of the present invention.

図１２を参照して、本実施の形態９は、実施の形態１と略同じ構成を含むので、実施の形態１と同構成の部分は、実施の形態１と同じ参照番号を付して、その説明を省略し、構成の異なる部分についてのみ説明する。   Referring to FIG. 12, the ninth embodiment includes substantially the same configuration as that of the first embodiment. Therefore, the same reference numerals as those in the first embodiment are assigned to the same components as those in the first embodiment. A description thereof will be omitted, and only different parts will be described.

図１２のように、本実施の形態９の剛体球検出用センサ１０３は、磁石３３ａ，３３ｂと磁性金属体１０５両端との間に磁性金属体１０５とは磁気特性の異なる磁性体１０７ａ，１０７ｂを密着させて配置されるようになっている。   As shown in FIG. 12, in the hard sphere detection sensor 103 according to the ninth embodiment, magnetic bodies 107a and 107b having different magnetic characteristics from the magnetic metal body 105 are provided between the magnets 33a and 33b and both ends of the magnetic metal body 105. It is arranged in close contact.

このように、本実施の形態９の剛体球検出用センサ１０３は、磁石と磁性金属体との間に配置した磁性体１０７ａ，１０７ｂの寸法を変えることで、リードスイッチ３１の両端の一方と磁石３３ａの端（Ｎ極）との距離を、リードスイッチ３１の両端の他方と磁石３３ｂの端（Ｓ極）との距離に対して、ほぼ自由に設定できるので、本実施の形態１の剛体球検出用センサと同等の検出精度を確保することが出来る。その磁性体３３ａ，３３ｂについては、金属には限らず、軟磁性フェライトなどの一般のものを用いることが出来る。   As described above, the hard sphere detection sensor 103 according to the ninth embodiment changes the size of the magnetic bodies 107a and 107b arranged between the magnet and the magnetic metal body, thereby changing one end of the reed switch 31 and the magnet. Since the distance from the end (N pole) of 33a can be set almost freely with respect to the distance between the other end of both ends of reed switch 31 and the end (S pole) of magnet 33b, the rigid sphere of the first embodiment Detection accuracy equivalent to that of the detection sensor can be ensured. The magnetic bodies 33a and 33b are not limited to metals, and general materials such as soft magnetic ferrite can be used.

図１３は本発明の請求項１４、請求項１５に係る、実施の形態１０の剛体球検出用センサを示す平面図である。   13 is a plan view showing a hard sphere detection sensor according to a tenth embodiment of the present invention.

図１３を参照して、本実施の形態１０は、実施の形態１と略同じ構成を含むので、実施の形態１と同構成の部分は、実施の形態１と同じ参照番号を付して、その説明を省略し、構成の異なる部分についてのみ説明する。   Referring to FIG. 13, the tenth embodiment includes substantially the same configuration as the first embodiment. Therefore, the same reference numerals as those in the first embodiment are assigned to the same components as those in the first embodiment. A description thereof will be omitted, and only different parts will be described.

図１３のように、本実施の形態１０の剛体球検出用センサ１０９は、リードスイッチ３１の外部端子１１５ａ，１１５ｂをヨーク（磁束誘導体）として電気的接続部より引き出し、駆動用の磁石１１３ａ，１１３ｂの側に外部端子１１５ａ，１１５ｂを向け、実装されるようになっている。   As shown in FIG. 13, the hard sphere detection sensor 109 according to the tenth embodiment uses the external terminals 115a and 115b of the reed switch 31 as yokes (magnetic flux derivatives), which are drawn out from the electrical connection portion, and drive magnets 113a and 113b. The external terminals 115a and 115b are directed to the side of the connector and mounted.

また、図１３の剛体球検出用センサ１０９では、リードスイッチ３１の外部端子１１５ａ，１１５ｂを駆動用の磁石１１３ａ，１１３ｂの側に向け引き出し、リードスイッチ３１の一方の端と磁石間の距離Ｌ７に比べ、他方の端と磁石間の距離Ｌ８が異なるように配置する。   In the rigid ball detection sensor 109 of FIG. 13, the external terminals 115a and 115b of the reed switch 31 are pulled out toward the drive magnets 113a and 113b, and the distance L7 between one end of the reed switch 31 and the magnet is set. In comparison, the distance L8 between the other end and the magnet is different.

これにより、リードスイッチの両端に到達する磁界の差は、各々の距離の２乗に反比例し、極めて大きな差となるために、遊技球が通過しない場合、各々の接点は異磁極に磁化され吸引（ＯＮ）しているものの、バランスが悪く、各々の接点が同一磁力で吸引している場合に比べ、吸引を解きやすい状態となり、貫通孔内を遊技球が通過すると、遊技球に磁束が吸引され、リードスイッチに到達する磁界が減少するため、ＯＦＦ状態になる構造となっている。   As a result, the difference in the magnetic field reaching both ends of the reed switch is inversely proportional to the square of each distance and is extremely large. Therefore, when the game ball does not pass, each contact is magnetized by a different magnetic pole and attracted. (ON) Although the balance is poor and each contact is attracted by the same magnetic force, it becomes easier to release the suction, and when the game ball passes through the through hole, the magnetic flux is attracted to the game ball. Since the magnetic field reaching the reed switch is reduced, the structure is turned off.

従って、本実施の形態１０の剛体球検出用センサ３５の検出精度が向上し、適合するリードスイッチの感動値範囲も広がり、安定した量産性を確保することが出来る。   Therefore, the detection accuracy of the hard sphere detection sensor 35 of the tenth embodiment is improved, the moving value range of the suitable reed switch is expanded, and stable mass productivity can be ensured.

図１４を参照して、本実施の形態１１は、実施の形態１と略同じ構成を含むので、実施の形態１と同構成の部分は、実施の形態１と同じ参照番号を付して、その説明を省略し、構成の異なる部分についてのみ説明する。   Referring to FIG. 14, the eleventh embodiment includes substantially the same configuration as that of the first embodiment. Therefore, the same reference numerals as those in the first embodiment are assigned to the same components as those in the first embodiment. A description thereof will be omitted, and only different parts will be described.

図１４を参照して、本実施の形態１１の剛体球検出用センサ１１７は、磁気感応スイッチがホールＩＣ１１９とスイッチング回路１２１、またはＭＲ素子１１９とスイッチング回路１２１からなっている。これにより、貫通孔内２７を遊技球が通過しない場合は、磁石３３ａ，３３ｂから磁界がホールＩＣまたはＭＲ素子１１９に到達し、ＯＮ状態となる。また、貫通孔２７内を遊技球が通過した場合の検出動作は、遊技球によって磁気回路は、磁石３３ａ、遊技球、磁石３３ｂ、磁性金属体３５からなる閉磁路を構成するため、ホールＩＣまたはＭＲ素子１１９に到達する磁界は著しく減少してＯＦＦ状態となる。   Referring to FIG. 14, in hard ball detection sensor 117 according to the eleventh embodiment, the magnetically sensitive switch includes Hall IC 119 and switching circuit 121 or MR element 119 and switching circuit 121. Thereby, when the game ball does not pass through the through hole 27, the magnetic field reaches the Hall IC or the MR element 119 from the magnets 33a and 33b, and is turned on. Further, the detection operation when the game ball passes through the through hole 27 is performed by using the Hall IC or the magnetic circuit because the magnetic circuit forms a closed magnetic circuit composed of the magnet 33a, the game ball, the magnet 33b, and the magnetic metal body 35. The magnetic field reaching the MR element 119 is remarkably reduced and is turned off.

従って、本実施の形態１１の剛体球検出用センサ１１７のように、磁気感応スイッチとしてホールＩＣ、ＭＲ素子（Magnetic Resistor）等を用いた場合にも、他の実施の形態と同様の効果が得られることは勿論である。   Therefore, even when a Hall IC, MR element (Magnetic Resistor), or the like is used as a magnetically sensitive switch like the hard sphere detection sensor 117 of the eleventh embodiment, the same effects as those of the other embodiments can be obtained. Of course.

However, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. It is included in this invention. For example, in the first embodiment, the ON / OFF relationship between the operating state and the non-operating state of the magnetically sensitive switch may be reversed. The magnetic metal body may be a combination of a plurality of magnetic metal bodies, or may be replaced with a general soft magnetic body such as ferrite. Furthermore, the magnet may be a magnet in which a plurality of magnets magnetized in the longitudinal direction are connected in the longitudinal direction, and the magnet may have any shape such as a rectangular parallelepiped or a round bar. Further, the relationship between the polarities of the magnets (N pole, S pole) may be reversed.
