Description

本発明は、金属球検出装置、金属球検出装置を用いたパチンコ遊技機及びパチンコ遊技機用の金属球検出モジュールに関する。 The present invention relates to a metal ball detection device, a pachinko game machine using the metal ball detection device, and a metal ball detection module for a pachinko game machine.

検出体の接触又は近接を検出する技術として、電磁誘導方式を用いた近接スイッチ（センサー）が知られている。電磁誘導方式を用いた誘導型の近接スイッチは、例えばセンサー部をなす検出コイルと、検出コイルに高周波磁界を生じさせる発振回路と、発振が減衰又は停止したかどうか発振状態を検出する発振状態検出回路と、検出体の接触又は近接を通知するための出力信号を発生する出力回路とを備えている。
そして検出コイルより生じる高周波磁界中に、金属等の導電性を有する検出体が接近することにより、検出体中に電磁誘導現象による誘導電流が流れ、検出体内で熱損失を発生させる。この熱損失は検出コイルを通じて、近接スイッチが備える発振回路より引き出されたものであるため、熱損失が発生すると、発振回路は発振状態を維持することができず、発振が減衰するか又は停止することになる。そして近接スイッチは、発振状態検出回路及び出力回路を介して、出力信号を直ちに発生するように構成されている。 A proximity switch (sensor) using an electromagnetic induction method is known as a technique for detecting contact or proximity of a detector. The induction type proximity switch using the electromagnetic induction method is, for example, a detection coil forming a sensor unit, an oscillation circuit that generates a high-frequency magnetic field in the detection coil, and an oscillation state detection that detects whether the oscillation is attenuated or stopped. It includes a circuit and an output circuit that generates an output signal for notifying the contact or proximity of the detector.
Then, when a detector having conductivity such as metal approaches the high-frequency magnetic field generated by the detection coil, an induced current due to an electromagnetic induction phenomenon flows in the detector, causing heat loss in the detector. Since this heat loss is drawn from the oscillation circuit of the proximity switch through the detection coil, when heat loss occurs, the oscillation circuit cannot maintain the oscillation state, and the oscillation is attenuated or stopped. It will be. The proximity switch is configured to immediately generate an output signal via the oscillation state detection circuit and the output circuit.

こうした電磁誘導方式の近接スイッチの一例として、パチンコ遊技機において金属球が接触又は通過したことを、金属球が通過できる程度の大きさの孔を中央に有するループコイルをセンサー部として備えた近接センサーにより検出する技術が提案されている（特許文献１参照。）。 As an example of such an electromagnetic induction type proximity switch, a proximity sensor provided as a sensor unit with a loop coil having a hole in the center large enough to allow the metal ball to pass through in a pachinko gaming machine. A technique for detecting by means of is proposed (see Patent Document 1).

しかし特許文献１の方法では、金属球がループコイル中央の孔を通過する構造であるため、ループコイルの外形を少なくとも直径１１ｍｍ程度の金属球のサイズより小さくすることは不可能である。通常は、直径１２ｍｍ程度以上の孔が形成される必要があるため、センサー部としてのループコイルの、金属球のサイズ以下への小型化は非常に難しい。すなわちセンサー部の寸法が検出体である金属球の寸法に大きく依存するため、十分に小型化できないという問題が生じていた。 However, in the method of Patent Document 1, since the metal ball passes through the hole in the center of the loop coil, it is impossible to make the outer shape of the loop coil smaller than the size of the metal ball having a diameter of at least about 11 mm. Normally, since it is necessary to form a hole having a diameter of about 12 mm or more, it is very difficult to reduce the size of the loop coil as a sensor portion to the size of a metal ball or less. That is, since the size of the sensor portion greatly depends on the size of the metal sphere which is the detector, there is a problem that the size cannot be sufficiently reduced.

本発明の実施の形態に係る金属球検出装置は、図１に示すように、移動する金属球８ｂ〜８ｆ，８ｈの移動経路の近傍に設けられた導電性を有する検出プレート１と、一端が検出プレート１に接続された接続配線３と、接続配線３の他端に接続され検出プレート１に対する金属球８ｂ〜８ｆ，８ｈの接触又は近接を自己容量型タッチセンサー駆動（セルフキャパシタンス）方式で検出する検出回路４と、を備える。
また本発明の実施の形態に係る金属球検出装置は、検出回路４に接続された検出信号出力回路５と、この検出信号出力回路５に接続された外部出力端子６と、を備える。検出回路４、検出信号出力回路５及び外部出力端子６は、図示を省略する駆動回路等と共に基板７上に搭載されている。尚、基板７上のそれぞれの回路はいずれも、図示を省略する電源に接続されている。 As shown in FIG. 1, the metal ball detection device according to the embodiment of the present invention has a conductive detection plate 1 provided in the vicinity of the movement path of the moving metal balls 8b to 8f, 8h, and one end thereof. The connection wiring 3 connected to the detection plate 1 and the contact or proximity of the metal balls 8b to 8f, 8h to the detection plate 1 connected to the other end of the connection wiring 3 are detected by a self-capacitance type touch sensor drive (self-capacitance) method. The detection circuit 4 is provided.
Further, the metal ball detection device according to the embodiment of the present invention includes a detection signal output circuit 5 connected to the detection circuit 4 and an external output terminal 6 connected to the detection signal output circuit 5. The detection circuit 4, the detection signal output circuit 5, and the external output terminal 6 are mounted on the substrate 7 together with a drive circuit and the like (not shown). Each circuit on the substrate 7 is connected to a power supply (not shown).

センサー部（１，２）は、図２に示すように、検出プレート１と、この検出プレート１の周囲を覆うように設けられたシート状の保護フィルム２とで構成されている。
検出プレート１はシート状であり、いずれも導電性の素材で構成され、シートの主面を正面から見て略長方形状の主領域を有する。この主領域の長方形の１組の短辺のうち図２中の下側に位置する短辺側には、主領域から主領域の外側に突出するように設けられた略正方形状の凸部が形成され、この凸部が接続配線３との電気的な接続部をなしている。 As shown in FIG. 2, the sensor units (1 and 2) are composed of a detection plate 1 and a sheet-shaped protective film 2 provided so as to cover the periphery of the detection plate 1.
The detection plate 1 has a sheet shape, is made of a conductive material, and has a main region having a substantially rectangular shape when the main surface of the sheet is viewed from the front. On the short side of the set of rectangular short sides of the main region, which is located on the lower side in FIG. 2, a substantially square convex portion provided so as to project from the main region to the outside of the main region is provided. It is formed, and this convex portion forms an electrical connection portion with the connection wiring 3.

主領域と凸部は一体的に形成されている。金属球８ｂ〜８ｆ，８ｈとの主たる接触表面をなす主領域とは別に、接続部としての凸部が設けられていることにより、一定の所望の検出領域を確実に担保した検出プレート１を構成できると共に、検出プレート１と接続配線３との連結作業を効率的に行うことができる。但し凸部は必須の構成ではなく、図４に示すように、主領域のみで検出プレート１を構成すると共に、主領域の一辺に接続配線３を直接連結させて、本発明の実施の形態に係る金属球検出装置を構成することも可能である。 The main region and the convex portion are integrally formed. A detection plate 1 that reliably secures a certain desired detection region is configured by providing a convex portion as a connecting portion in addition to the main region forming the main contact surface with the metal balls 8b to 8f and 8h. At the same time, the connection work between the detection plate 1 and the connection wiring 3 can be efficiently performed. However, the convex portion is not an indispensable configuration, and as shown in FIG. 4, the detection plate 1 is configured only in the main region, and the connection wiring 3 is directly connected to one side of the main region to form the embodiment of the present invention. It is also possible to configure such a metal ball detection device.

また検出プレート１の主領域の形状は長方形に限定されず、正方形等の他の形状に適宜変更可能である。接続部をなす凸部の形状も正方形状に限定されず他の形状に適宜変更されてよい。検出プレート１は、保護フィルム２との密着性及び成形性を高めるために、例えば粘着テープ等で構成できる。 Further, the shape of the main region of the detection plate 1 is not limited to a rectangle, and can be appropriately changed to another shape such as a square. The shape of the convex portion forming the connecting portion is not limited to the square shape, and may be appropriately changed to another shape. The detection plate 1 can be made of, for example, an adhesive tape or the like in order to improve the adhesion and moldability with the protective film 2.

ここで、検出プレート１の検出領域の面積が、例えば１００ｍｍ^２以内といった一定値に限定されるような条件である場合、検出プレート１の主領域の形状は、正方形よりも長方形である方が好ましい。検出プレート１を長方形状に構成することにより、検出プレート１の接続配線３の付け根と反対側に位置する先端の、接続配線３との付け根からの距離を長くして、検出プレート１面内における電流の分布を変化させることが可能になる。これにより、検出プレート１の先端側の領域における検出感度を、他の領域の感度に比べて高くするように制御することができ、この高感度の検出領域を用いて、金属球８ｂ〜８ｆ，８ｈをより高精度で検出することができる。 Here, when the area of the detection region of the detection plate 1 is limited to a constant value such as within 100 mm ² , the shape of the main region of the detection plate 1 is preferably rectangular rather than square. .. By forming the detection plate 1 in a rectangular shape, the distance from the base of the connection wiring 3 at the tip opposite to the base of the connection wiring 3 of the detection plate 1 can be increased, and the distance from the base of the connection wiring 3 can be increased in the detection plate 1 surface. It is possible to change the distribution of current. Thereby, the detection sensitivity in the region on the tip side of the detection plate 1 can be controlled to be higher than the sensitivity in the other regions, and the metal balls 8b to 8f, using this highly sensitive detection region, 8h can be detected with higher accuracy.

また検出プレート１の主領域の形状が長方形である場合、厚みｔを考慮しない条件で、縦横比（長辺の長さＬ／短辺の長さＷ）が２以上になるように検出プレート１を構成すると、先端側の領域の検出感度を高める効果を明確に得られる。 When the shape of the main region of the detection plate 1 is rectangular, the detection plate 1 has an aspect ratio (long side length L / short side length W) of 2 or more under the condition that the thickness t is not taken into consideration. The effect of increasing the detection sensitivity of the region on the tip side can be clearly obtained.

保護フィルム２は表側シート２１及び裏側シート２２からなり、表側シート２１及び裏側シート２２はいずれもプラスチック等の絶縁性を有する樹脂素材で構成されている。図２に例示した表側シート２１及び裏側シート２２は、互いに同形状及び同寸法であって、一体性が高められている。 The protective film 2 is composed of a front side sheet 21 and a back side sheet 22, and both the front side sheet 21 and the back side sheet 22 are made of a resin material having an insulating property such as plastic. The front side sheet 21 and the back side sheet 22 illustrated in FIG. 2 have the same shape and the same size as each other, and the integrity is enhanced.

保護フィルム２をなす２枚のシート２１、２２が検出プレート１を厚み方向から挟んで、保護フィルム２の中央の領域で表側シート２１、検出プレート１及び裏側シート２２の３層が、互いに密着するように接合され、センサー部（１，２）が構成されている。また接続配線３のセンサー部（１，２）の付け根側の端部も部分的に、表側シート２１及び裏側シート２２に挟まれてセンサー部（１，２）に固定されている。保護フィルム２はセンサー部（１，２）の表面を汚れ等から保護すると共に、静電気ノイズを低減する。 The two sheets 21 and 22 forming the protective film 2 sandwich the detection plate 1 from the thickness direction, and the three layers of the front side sheet 21, the detection plate 1 and the back side sheet 22 are in close contact with each other in the central region of the protective film 2. The sensor portions (1, 2) are configured as such. Further, the end portions of the connection wiring 3 on the root side of the sensor portions (1, 2) are also partially sandwiched between the front side sheet 21 and the back side sheet 22 and fixed to the sensor portions (1, 2). The protective film 2 protects the surfaces of the sensor portions (1, 2) from dirt and the like, and reduces electrostatic noise.

尚、図２中では、検出プレート１及び保護フィルム２の厚みが、説明の便宜のため、強調して厚く描かれているが、実際にはそれぞれの厚みは例えば０．１ｍｍオーダであり、非常に薄い。そのため検出プレート１が挟まれていても、表側シート２１及び裏側シート２２の間に生じる隙間は殆ど無視できる程度に、検出プレート１及び保護フィルム２は一体化されている。 In FIG. 2, the thicknesses of the detection plate 1 and the protective film 2 are emphasized and drawn thick for convenience of explanation, but in reality, the thicknesses of each are, for example, 0.1 mm, which is extremely high. Thin. Therefore, even if the detection plate 1 is sandwiched, the detection plate 1 and the protective film 2 are integrated so that the gap generated between the front side sheet 21 and the back side sheet 22 can be almost ignored.

また保護フィルム２の上には、図示を省略するがポリエチレンテレフタラート（ＰＥＴ）等の絶縁性を有する樹脂素材で構成されたシートを、厚み追加層として積層して接着させ、保護フィルム２の見かけ上の厚みを増大させて、保護フィルム２単体の厚さのみではセンサー部（１，２）の強度やコシが足りない場合や、静電気対策が不十分である場合に対応することができる。また厚み追加層を積層することにより、検出プレート１と金属球８ｂ〜８ｆ，８ｈとの間隔を拡げることが可能になる。 Further, on the protective film 2, a sheet made of an insulating resin material such as polyethylene terephthalate (PET), which is not shown, is laminated and adhered as a thickness additional layer to obtain the appearance of the protective film 2. By increasing the thickness of the upper part, it is possible to cope with the case where the strength and stiffness of the sensor portions (1, 2) are insufficient or the countermeasure against static electricity is insufficient only by the thickness of the protective film 2 alone. Further, by laminating the thickness additional layer, it is possible to widen the distance between the detection plate 1 and the metal balls 8b to 8f and 8h.

また図１に示すように、本発明の実施の形態に係る金属球検出装置には、検出プレート１及び保護フィルム２からなるセンサー部（１，２）を支持する支持台１３が設けられている。支持台１３は、１枚の板状部材を略Ｌ字状をなすように折り曲げて形成され、Ｌ字の長辺をなす側の領域の、Ｌ字の短辺が延びる方向と反対側の主面上の一定の高さ位置に、センサー部（１，２）が支持台１３の主面と面接合して、検出プレート１の検出領域側の面を金属球８ｂ〜８ｆ，８ｈ側に対向させて取り付けられている。 Further, as shown in FIG. 1, the metal ball detection device according to the embodiment of the present invention is provided with a support base 13 for supporting the sensor portions (1, 2) composed of the detection plate 1 and the protective film 2. .. The support base 13 is formed by bending one plate-shaped member so as to form a substantially L-shape, and is a main region on the side forming the long side of the L-shape, which is opposite to the direction in which the short side of the L-shape extends. At a certain height position on the surface, the sensor portions (1, 2) are surface-bonded to the main surface of the support base 13, and the surface of the detection plate 1 on the detection region side faces the metal balls 8b to 8f, 8h. It is attached by letting.

接続配線３はシールド線等で構成できる。接続配線３を用いることにより、センサー部（１，２）と検出回路４とを所望の距離で互いに離間させて配置できる。また本発明の実施の形態に係る金属球検出装置のようにセルフキャパシタンス方式の検出装置の場合、センサー部（１，２）自体の持つ容量が小さいほど感度が良くなる。一方、センサー部（１，２）と検出回路４とを接続配線３で中継して接続した場合、接続配線３の持つ容量もセンサー部（１，２）の容量に付加され、検出装置全体の容量を押し上げる。すなわち検出感度は、センサー部（１，２）自体の容量の大きさだけでなく、接続配線３の容量から影響を受ける。 The connection wiring 3 can be configured by a shielded wire or the like. By using the connection wire 3 can be arranged by spaced apart from each other a sensor part (1, 2) and detection circuit 4 at a desired distance. Further, in the case of a self-capacitance type detection device such as the metal ball detection device according to the embodiment of the present invention, the smaller the capacitance of the sensor units (1, 2) itself, the better the sensitivity. On the other hand, when the sensor unit (1, 2) and the detection circuit 4 are relayed and connected by the connection wiring 3, the capacity of the connection wiring 3 is also added to the capacity of the sensor unit (1, 2), and the entire detection device is connected. Push up capacity. That is, the detection sensitivity is affected not only by the magnitude of the capacitance of the sensor units (1, 2) itself, but also by the capacitance of the connection wiring 3.

そのため、高い容量を持つ接続配線３を使用すると、検出感度が低下することになる。通常、接続配線３の容量はその長さに比例して高くなることから、本発明の実施の形態に係る金属球検出装置の場合、検出装置全体で見た場合の検出感度を考慮して、接続配線３の長さを、配置上で必要な最小限の長さに設定し、感度低下を可能な限り抑制している。 Therefore, if the connection wiring 3 having a high capacity is used, the detection sensitivity will be lowered. Normally, the capacity of the connection wiring 3 increases in proportion to its length. Therefore, in the case of the metal ball detection device according to the embodiment of the present invention, the detection sensitivity when viewed from the entire detection device is taken into consideration. The length of the connection wiring 3 is set to the minimum length necessary for arrangement, and the decrease in sensitivity is suppressed as much as possible.

検出回路４は、センサー部（１，２）に金属球８ｂ〜８ｆ，８ｈが接触又は近接した場合、センサー部（１，２）から入力される信号の変化を検出し、検出信号出力回路５に、検出信号を生成するための指令を出力する。
検出信号出力回路５は、検出回路４からの指令が入力されると検出信号を生成し、生成した検出信号を外部出力端子６に出力する。
外部出力端子６は、検出信号出力回路５から検出信号が入力されると、入力された検出信号を、２ビットのデジタル信号（０１信号）に変換して、外部、例えばパチンコ遊技機において金属球８ｂ〜８ｆ，８ｈの移動及び役物の動作を制御する不図示の制御装置等に対して出力する。 The detection circuit 4 detects a change in the signal input from the sensor units (1, 2) when the metal balls 8b to 8f, 8h come into contact with or are close to the sensor units (1, 2), and the detection signal output circuit 5 Outputs a command to generate a detection signal.
The detection signal output circuit 5 generates a detection signal when a command from the detection circuit 4 is input, and outputs the generated detection signal to the external output terminal 6.
When the detection signal is input from the detection signal output circuit 5, the external output terminal 6 converts the input detection signal into a 2-bit digital signal (01 signal) and converts the input detection signal into a metal ball externally, for example, in a pachinko game machine. It is output to a control device (not shown) that controls the movement of 8b to 8f and 8h and the operation of the accessory.

回転装置（９，１０，１１，１２ａ〜１２ｈ）は、図１に示すように、略円柱状の回転軸９と、この回転軸９が中心を貫通して回転軸９に同心で取り付けられた円盤１０と、円盤１０を回転自在に支持する懸架台１１と、を備え、円盤１０の盤面上に設けられた吸着部１２ａ〜１２ｈを介して金属球８ｂ〜８ｆ，８ｈを支持し、盤面に平行な面内で回転させる。 As shown in FIG. 1, the rotating device (9, 10, 11, 12a to 12h) has a substantially cylindrical rotating shaft 9 and the rotating shaft 9 concentrically attached to the rotating shaft 9 through the center. A disk 10 and a suspension 11 for rotatably supporting the disk 10 are provided, and metal balls 8b to 8f and 8h are supported on the disk surface via suction portions 12a to 12h provided on the disk surface of the disk 10. Rotate in parallel planes.

回転軸９、円盤１０及び懸架台１１は、いずれも絶縁性を有する素材で構成されている。回転軸９は不図示の回転駆動装置に接続される。懸架台１１は、平板状の底板１１ａと、底板１１ａの一方の主面上に、この主面に対して垂直に延びるように設けられた２枚の柱板１１ｂ，１１ｃと、を備える。 The rotating shaft 9, the disk 10, and the suspension stand 11 are all made of an insulating material. The rotary shaft 9 is connected to a rotary drive device (not shown). The suspension base 11 includes a flat bottom plate 11a and two pillar plates 11b and 11c provided on one main surface of the bottom plate 11a so as to extend perpendicular to the main surface.

柱板１１ｂ，１１ｃは、それぞれの主面が互いに平行になるように間隔を空けて設けられている。柱板１１ｂ，１１ｃの底板１１ａと反対側の端部には、回転軸９が回転自在に差し込まれて支持される支持孔が、同軸上にそれぞれ設けられている。柱板１１ｂ，１１ｃの支持孔によって、回転軸９の両端が回転自在に支持されることにより円盤１０が懸架台１１上で回転軸９の回転に伴って回転する。 The pillar plates 11b and 11c are provided at intervals so that their main surfaces are parallel to each other. Support holes for rotatably inserting and supporting the rotating shaft 9 are provided coaxially at the ends of the pillar plates 11b and 11c on the opposite side of the bottom plate 11a. Both ends of the rotating shaft 9 are rotatably supported by the support holes of the column plates 11b and 11c, so that the disk 10 rotates on the suspension stand 11 as the rotating shaft 9 rotates.

吸着部１２ａ〜１２ｈは、磁石等の磁性を有する部材で構成され、磁力により金属球８ｂ〜８ｆ，８ｈを吸着して保持する。図１中には８個の略円板状の吸着部１２ａ〜１２ｈが、円盤１０の盤面上の周縁近傍に略等間隔で設置された状態が例示されているが、吸着部１２ａ〜１２ｈの個数や形状は、適宜変更されてよい。 The attracting portions 12a to 12h are composed of magnetic members such as magnets, and attract and hold the metal balls 8b to 8f and 8h by magnetic force. FIG. 1 illustrates a state in which eight substantially disk-shaped suction portions 12a to 12h are installed at substantially equal intervals near the peripheral edge of the disk surface of the disk 10, but the suction portions 12a to 12h The number and shape may be changed as appropriate.

＜パチンコ遊技機＞
本発明の実施の形態に係る金属球検出装置は、図３に示すように、例えばパチンコ遊技機のケースの内部に設けて適用できる。図３に例示したパチンコ遊技機の場合、ケースの内部では、円盤１０は主面がパチンコ遊技機の前に座る遊戯者の視線の方向に略直交するように配置された状態で、正面から見て時計回り（右回り）で回転するように設けられている。そして円盤１０が回転する際、円盤１０の周縁近傍に設けられた吸着部１２ａ〜１２ｈが、ケースの内部で最下段の位置を転がって移動する金属球８ａ〜８ｈに対して、金属球８ａ〜８ｈと略同じ高さを通過するように構成されている。 <Pachinko game machine>
As shown in FIG. 3, the metal ball detection device according to the embodiment of the present invention can be applied by being provided inside, for example, the case of a pachinko gaming machine. In the case of the pachinko gaming machine illustrated in FIG. 3, inside the case, the disk 10 is viewed from the front with the main surface arranged so as to be substantially orthogonal to the direction of the line of sight of the player sitting in front of the pachinko gaming machine. It is provided to rotate clockwise (clockwise). Then, when the disk 10 rotates, the suction portions 12a to 12h provided near the peripheral edge of the disk 10 roll the metal balls 8a to 8h at the lowest position inside the case, and the metal balls 8a to 8a to 8h. It is configured to pass approximately the same height as 8h.

そのため、複数の吸着部１２ａ〜１２ｈのうちいずれかが最下段の位置を通過する際に、金属球８ａ〜８ｈが吸着部１２ａ〜１２ｈの吸着可能範囲内に存在していれば、金属球８ａ〜８ｈは吸着部１２ａ〜１２ｈ上に保持され、円盤１０の回転に伴って左上、右上、右下及び左下の順に円運動するように搬送される。この搬送には重力に抗して上方へ移動する経路も含まれている。
また、円盤１０が金属球８ａ〜８ｈを保持した状態で所定の回数回転する間に、例えばケースの内部で上方からクレーンが降下して、吸着部１２ａ〜１２ｈに保持されている金属球８ａ〜８ｈを挟んで吊り上げたりするような、別の役物演出との併用も可能である。 Therefore, when any one of the plurality of suction portions 12a to 12h passes through the lowest position, if the metal balls 8a to 8h are within the suction range of the suction portions 12a to 12h, the metal balls 8a ~ 8h is held on the suction portions 12a to 12h, and is conveyed so as to make a circular motion in the order of upper left, upper right, lower right, and lower left as the disk 10 rotates. This transport also includes a path that moves upward against gravity.
Further, while the disk 10 rotates a predetermined number of times while holding the metal balls 8a to 8h, for example, the crane descends from above inside the case, and the metal balls 8a to held by the suction portions 12a to 12h. It can also be used in combination with another character effect, such as lifting with 8h in between.

このとき盤面上で、移動する金属球の位置を検出するために、中央の孔を通過させることで位置を検出するループコイル状のセンサー部を用いるとすると、孔の軸方向が金属球の移動方向に沿うように、ループコイルを円盤１０上で、盤面に殆ど接触した状態で設けざるを得なくなる。そのためループコイルが金属球８ａ〜８ｈの吸着部１２ａ〜１２ｈとの吸着状態を断ち切ってしまい、役物が成り立たなくなる。 At this time, if a loop coil-shaped sensor unit that detects the position by passing through the central hole is used to detect the position of the moving metal ball on the board surface, the axial direction of the hole is the movement of the metal ball. The loop coil must be provided on the disk 10 so as to be in contact with the surface of the disk so as to follow the direction. Therefore the loop coils will be Tsu sever the adsorption state of the adsorption unit 12a~12h of metal balls 8a to 8h, the character object is not satisfied.

一方、図３に示したパチンコ遊技機の場合、本発明の実施の形態に係る金属球検出装置のセンサー部（１，２）は、長方形の長辺が円盤１０の主面と平行に、かつ、センサー部（１，２）の主面が円盤１０の半径方向と直交する状態で、盤面に非接触で配置可能である。またセンサー部（１，２）は薄いシート状に小型化されているので、センサー部（１，２）を円盤１０の可動範囲すなわち面内に設置しても、役物の動作に対してセンシング動作が及ぼす影響を極力抑えることができる。 On the other hand, in the case of the pachinko gaming machine shown in FIG. 3, the sensor portions (1, 2) of the metal ball detection device according to the embodiment of the present invention have a rectangular long side parallel to the main surface of the disk 10. , The main surface of the sensor portions (1, 2) can be arranged in a non-contact manner with the disk surface in a state of being orthogonal to the radial direction of the disk 10. Further, since the sensor units (1, 2) are miniaturized into a thin sheet, even if the sensor units (1, 2) are installed in the movable range of the disk 10, that is, in the plane, they sense the movement of the accessory. The influence of movement can be suppressed as much as possible.

またパチンコ遊技機のケースの内部領域は、遊戯者側に張り出す奥行き方向の長さｄが、通常、長くても数ｃｍ程度の比較的狭い空間である。この空間内にループコイルを配置すると、様々な方向に移動する複数の金属球の移動が大きく妨げられてしまう。しかし本発明の実施の形態に係る金属球検出装置のセンサー部（１，２）は、厚みｔが例えば０．２ｍｍ〜０．３ｍｍ程度で構成できる薄いシート状であり、かつ、奥行き方向に沿った幅Ｗも例えば５ｍｍ程度で構成できるため、狭いケースの内部に配置しても、金属球の移動や役物の動作への干渉を大きく抑制できる。また配置の自由度も高い。 Further, the internal area of the case of the pachinko game machine is a relatively narrow space in which the length d in the depth direction overhanging the player side is usually about several cm at the longest. If the loop coil is arranged in this space, the movement of a plurality of metal balls moving in various directions is greatly hindered. However, the sensor portions (1, 2) of the metal ball detection device according to the embodiment of the present invention have a thin sheet shape having a thickness t of, for example, about 0.2 mm to 0.3 mm, and are in the depth direction. Since the width W can be configured to be, for example, about 5 mm, even if it is arranged inside a narrow case, it is possible to greatly suppress the movement of the metal ball and the interference with the movement of the accessory. There is also a high degree of freedom in placement.

尚、図３中では、センサー部（１，２）は、金属球８ａ〜８ｈと、金属球８ａ〜８ｈの外側の領域で接触する位置に配置されているが、これに限定されない。例えば接続配線３は円盤１０の回転軸の内部を通すようにした上で、センサー部（１，２）を金属球８ａ〜８ｈと、金属球８ａ〜８ｈの内側の領域で接触する位置に配置するように構成する変形例も、本発明の主旨を逸脱するものではない。 In FIG. 3, the sensor portions (1, 2) are arranged at positions where they come into contact with the metal balls 8a to 8h in the outer region of the metal balls 8a to 8h, but the present invention is not limited to this. For example, the connection wiring 3 is passed through the inside of the rotating shaft of the disk 10, and the sensor portions (1 and 2) are arranged at positions where they come into contact with the metal balls 8a to 8h in the inner region of the metal balls 8a to 8h. The modified example configured to do so does not deviate from the gist of the present invention.

また本発明の実施の形態に係る金属球検出装置の場合、検出プレート１ａを銅テープ等の、また保護フィルム２ａをラミネートフィルム等の、それぞれ一定の柔軟性を有する素材を用いてセンサー部（１ａ，２ａ）を作成すると共に、図４（ａ）及び図４（ｂ）に示すように、センサー部（１ａ，２ａ）の付け根の領域を中心に部分的に支持台１３に接合させ、その他の大部分を占める非接合部分によってセンサー部（１ａ，２ａ）が柔軟性を有するように構成することができる。 Further, in the case of the metal ball detection device according to the embodiment of the present invention, the sensor unit (1a) uses a material having a certain degree of flexibility, such as a copper tape for the detection plate 1a and a laminated film for the protective film 2a. , 2a) are created, and as shown in FIGS. 4 (a) and 4 (b), the area at the base of the sensor unit (1a, 2a) is partially joined to the support base 13 and other parts. The sensor portion (1a, 2a) can be configured to have flexibility by the non-joint portion which occupies the majority.

図４に示したセンサー部（１ａ，２ａ）によれば、センサー部（１ａ，２ａ）全体が、金属球８ａ〜８ｈに接触による衝撃を、衝撃の向きに逆らわず受け流すように、金属球８ａ〜８ｈから離れるように撓んで、衝撃を緩和する。すなわち「衝撃緩和構造」がセンサー部（１ａ，２ａ）の構造によって実現されている。またセンサー部（１ａ，２ａ）全体が可撓性を有するので、金属球８ａ〜８ｈの通過後は、センサー部（１ａ，２ａ）が撓む前の形状に自動的に復元して金属球８ａ〜８ｈの通過前の検出状態に戻る。 According to the sensor units (1a, 2a) shown in FIG. 4, the metal sphere 8a is such that the entire sensor unit (1a, 2a) receives the impact due to contact with the metal spheres 8a to 8h without going against the direction of the impact. Bend away from ~ 8h to cushion the impact. That is, the "impact mitigation structure" is realized by the structure of the sensor unit (1a, 2a). Further, since the entire sensor portion (1a, 2a) has flexibility, after passing through the metal spheres 8a to 8h, the sensor portion (1a, 2a) is automatically restored to the shape before bending, and the metal sphere 8a It returns to the detection state before passing for ~ 8h.

次に、実施例の基本構造の一部の要件を変更させて、本発明の実施の形態に係る金属球検出装置の特性を確認する実験１〜４を行った。
（実験１）
実施例の基本構造において、検出プレート１ａの面積を変化させてセンサー感度（検出感度）を測定した実験１の結果を図５に示す。検出プレート１ａには、図４（ａ）に示したように、検出ポイントＰ１が１箇所設けられ、検出プレート１ａの主領域と回転移動する金属球８ａ〜８ｈとが最も近接する場所に、検出ポイントＰ１の中心が位置するようにセンサー部（１ａ，２ａ）を配置した。尚、図５中の感度の値は、検出ポイントＰ１で連続して測定された範囲における単位時間当りの感度の平均値で表している。 Next, experiments 1 to 4 were carried out to confirm the characteristics of the metal ball detection device according to the embodiment of the present invention by changing some requirements of the basic structure of the embodiment.
(Experiment 1)
FIG. 5 shows the result of Experiment 1 in which the sensor sensitivity (detection sensitivity) was measured by changing the area of the detection plate 1a in the basic structure of the embodiment. As shown in FIG. 4A, the detection plate 1a is provided with one detection point P1 and detects the main region of the detection plate 1a and the rotating metal balls 8a to 8h at the closest positions. The sensor units (1a, 2a) were arranged so that the center of the point P1 was located. The sensitivity value in FIG. 5 is represented by the average value of the sensitivities per unit time in the range continuously measured at the detection point P1.

図５に示すように、検出プレート１ａの厚みｔが約０．１５ｍｍ以下であると共に、面積が１００ｍｍ^２以下である場合、検出感度は目標感度を上回り、良好な結果を得た。図６中には、実施例２の場合における検出プレート１ａ上の約２６０μｍ〜約５４０μｍの位置の検出ポイントＰ１で得られた感度の測定結果が示されている。 As shown in FIG. 5, when the thickness t of the detection plate 1a is about 0.15 mm or less and the area is 100 mm ² or less, the detection sensitivity exceeds the target sensitivity and good results are obtained. FIG. 6 shows the measurement result of the sensitivity obtained at the detection point P1 at the position of about 260 μm to about 540 μm on the detection plate 1a in the case of Example 2.

また検出プレート１ａの厚みを変化させて同様の実験を繰り返し行った。その結果、厚みｔが約０．１５ｍｍ以下である場合には、いずれも面積が１００ｍｍ^２以下であると良好な結果を得られることが分かった。 Further, the same experiment was repeated by changing the thickness of the detection plate 1a. As a result, it was found that when the thickness t is about 0.15 mm or less, good results can be obtained when the area is 100 mm ² or less.

（実験２）
次に、実施例の基本構造において、接続配線３の長さすなわち容量を変化させて検出感度を測定した場合の結果を、図７に示す。
図７中の「実施例４」のプロットが示すように、接続配線３の長さが約２０ｃｍ（容量約１４０ｐＦ）の場合、検出感度が１９４であった。また「実施例５」のプロットが示すように、接続配線３の長さが約３０ｃｍ（容量約２１０ｐＦ）の場合、検出感度が１８９であった。また「比較例３」のプロットが示すように、接続配線３の長さが約４０ｃｍ（容量約２８０ｐＦ）の場合、検出感度が２７であった。また「比較例４」のプロットが示すように、接続配線３の長さが約５０ｃｍ（容量約３５０ｐＦ）の場合、検出感度が０であった。 (Experiment 2)
Next, in the basic structure of the embodiment, the result when the detection sensitivity is measured by changing the length, that is, the capacitance of the connection wiring 3 is shown in FIG.
As shown in the plot of "Example 4" in FIG. 7, when the length of the connection wiring 3 was about 20 cm (capacity: about 140 pF), the detection sensitivity was 194. Further, as shown in the plot of "Example 5", when the length of the connection wiring 3 was about 30 cm (capacity: about 210 pF), the detection sensitivity was 189. Further, as shown in the plot of "Comparative Example 3", when the length of the connecting wiring 3 was about 40 cm (capacity: about 280 pF), the detection sensitivity was 27. Further, as shown in the plot of "Comparative Example 4", when the length of the connecting wiring 3 was about 50 cm (capacity: about 350 pF), the detection sensitivity was 0.

また図７の結果を用いて指数関数近似を行ってフィッティングし、接続配線３の長さの値に対応する検出感度の値を算出した結果を図８に示す。図７及び図８の結果より、接続配線３の長さ以外、本実施例の基本構造を用いた条件においては、接続配線３の長さが約３９ｃｍ以下になると、急激な感度低下が生じることが分かった。これにより、容量ベースでは、接続配線３が約２６０ｐＦ以下の容量であれば、十分な検出感度を得られることが分かった。 Further, FIG. 8 shows the result of calculating the value of the detection sensitivity corresponding to the value of the length of the connecting wiring 3 by performing the exponential function approximation using the result of FIG. 7 and fitting. From the results of FIGS. 7 and 8, under the conditions using the basic structure of this embodiment other than the length of the connecting wiring 3, when the length of the connecting wiring 3 is about 39 cm or less, a sharp decrease in sensitivity occurs. I understood. From this, it was found that, on a capacitance basis, sufficient detection sensitivity can be obtained if the connection wiring 3 has a capacitance of about 260 pF or less.

（実験３）
次に、実施例の基本構造において、厚み追加層としてＰＥＴシート（コニカ製、約０．１ｍｍ厚）を保護フィルム２ａの上に積層して検出感度を測定した場合の結果を、図９に示す。図９に示すように、検出プレート１ａと金属球８ａ〜８ｈの間の絶縁距離が約０．２ｍｍ以下である場合に良好な結果を得られることが分かった。 (Experiment 3)
Next, in the basic structure of the example, a result when a PET sheet (manufactured by Konica, about 0.1 mm thick) is laminated on the protective film 2a as a thickness additional layer and the detection sensitivity is measured is shown in FIG. .. As shown in FIG. 9, it was found that good results can be obtained when the insulation distance between the detection plate 1a and the metal balls 8a to 8h is about 0.2 mm or less.

（実験４）
次に、実施例の基本構造における検出プレート１ａの形状を変更して、図１０（ａ）に示すような、２箇所の検出ポイントＰ１，Ｐ２を有する長方形状のセンサー部（１ｂ,２ｂ）を備える金属球検出装置を「実施例７」として用意した。また図１０（ｂ）に示すような、３箇所の検出ポイントＰ１,Ｐ２,Ｐ３を有する長方形状のセンサー部（１ｃ,２ｃ）を備える金属球検出装置を「実施例８」として用意した。 (Experiment 4)
Next, the shape of the detection plate 1a in the basic structure of the embodiment is changed to provide rectangular sensor portions (1b, 2b) having two detection points P1 and P2 as shown in FIG. 10A. The metal ball detection device provided was prepared as "Example 7". Further, as shown in FIG. 10B, a metal ball detection device including a rectangular sensor unit (1c, 2c) having three detection points P1, P2, P3 was prepared as “Example 8”.

実施例７の検出プレート１ｂは、短辺が約５ｍｍ、長辺が約２０ｍｍであり、表面積が約１００ｍｍ^２である。また実施例８の検出プレート１ｃは、短辺が約５ｍｍ、長辺が約４０ｍｍであり、表面積が約２００ｍｍ^２である。
尚、実験４では、実施例７及び実施例８のそれぞれのセンサー部が有する複数の検出ポイントのそれぞれと金属球８ａ〜８ｈとの最近接距離がいずれも等しくなるように、センサー部を金属球８ａ〜８ｈの回転移動の軌跡に応じて撓ませた状態で配置した。 The detection plate 1b of Example 7 has a short side of about 5 mm, a long side of about 20 mm, and a surface area of about 100 mm ² . The detection plate 1c of Example 8 has a short side of about 5 mm, a long side of about 40 mm, and a surface area of about 200 mm ² .
In Experiment 4, the sensor unit was made of a metal ball so that the closest distance between each of the plurality of detection points of each of the sensor units of Example 7 and Example 8 and the metal balls 8a to 8h was equal. It was arranged in a bent state according to the locus of rotational movement of 8a to 8h.

実施例７及び実施例８の検出感度の測定結果を、上記した実施例２の測定結果と共に図１１中に示す。実施例２、実施例７及び実施例８は、いずれも検出プレートの幅Ｗが５ｍｍである点で共通する。尚、実験４では目標感度を６０に設定した。図１１中に示した感度の値のうち斜線を付した値は、目標感度６０を超えた良好な結果であることを示す。 The measurement results of the detection sensitivities of Examples 7 and 8 are shown in FIG. 11 together with the measurement results of Example 2 described above. Example 2, Example 7, and Example 8 are all common in that the width W of the detection plate is 5 mm. In Experiment 4, the target sensitivity was set to 60. Among the sensitivity values shown in FIG. 11, the shaded values indicate that the target sensitivity 60 is exceeded and the result is good.

また図１２中には、実施例７の場合における、検出プレート１ｂ上の約２６０μｍ〜約５４０μｍの位置の検出ポイントＰ１と、約６９０μｍ〜約９１０μｍの位置の検出ポイントＰ２とで得られた検出感度の測定結果が示されている。また図１３中には、実施例８の場合における、検出プレート１ｃ上の約３１０μｍ〜約５２０μｍの位置の検出ポイントＰ１と、約６６０μｍ〜約８８０μｍの位置の検出ポイントＰ２と、約１０８０μｍ〜約１２８０μｍの位置の検出ポイントＰ３とで得られた検出感度の測定結果が示されている。 Further, in FIG. 12, the detection sensitivities obtained at the detection point P1 at the position of about 260 μm to about 540 μm and the detection point P2 at the position of about 690 μm to about 910 μm on the detection plate 1b in the case of Example 7 are shown.

Further, in FIG. 13, in the case of Example 8, the detection point P1 at a position of about 310 μm to about 520 μm on the detection plate 1c, the detection point P2 at a position of about 660 μm to about 880 μm, and about 1080 μm to about 1280 μm are shown. The measurement result of the detection sensitivity obtained at the detection point P3 at the position of is shown.

また図１４中に、図１１で得られた測定結果を用いて、実施例２、実施例７及び実施例８のそれぞれの検出ポイント毎の感度を上下方向にプロットして並べて示す。図１４に示すように、検出プレートの幅Ｗを５ｍｍで固定して長さＬを変化させると、検出プレートの先端の検出ポイントが、同じ検出プレートの中での検出感度が最も高くなることが分かった。また検出プレートの先端以外の検出ポイントの、先端の検出ポイントに対する感度の低下幅は、検出プレートの根元側に位置する程大きくなった。 Further, in FIG. 14, using the measurement results obtained in FIG. 11, the sensitivities of each detection point of Example 2, Example 7, and Example 8 are plotted vertically and shown side by side. As shown in FIG. 14, when the width W of the detection plate is fixed at 5 mm and the length L is changed, the detection point at the tip of the detection plate has the highest detection sensitivity in the same detection plate. Do you get it. Further, the decrease in sensitivity of the detection points other than the tip of the detection plate to the detection point at the tip became larger as it was located closer to the root side of the detection plate.

また検出プレートの面積が大きくなるほど、検出ポイント間の感度の低下幅が大きくなり、面内のバラつきが大きくなると共に、最も高感度である先端の検出ポイントの感度も低下することが分かった。 It was also found that as the area of the detection plate increases, the range of decrease in sensitivity between detection points increases, the variation in the plane increases, and the sensitivity of the detection point at the tip, which is the most sensitive, also decreases.

Then, if the fixing portion 20a3 is fixed to the support base 13 side and the sensor portion (1, 2) is rotatably connected via the pedestal portion 20a1, the metal balls 8a to 8h collide with the sensor portion (1,2). Even so, the sensor units (1, 2) can rotate to alleviate the impact. At that time, for example, if a certain amount of urging force is applied to the fixed portion 20a3 in advance so that the fixed portion 20a3 is restored to the position before the collision, the sensor portion (1) is passed after the metal balls 8a to 8h pass. , 2) are automatically restored to their original positions.

Further, after passing through the metal balls 8a to 8h, the sensor portions (1, 2) are automatically restored to their original positions by the restoring force of the elastic portions 20b1.

（第３変形例）
また図１７に示した第３変形例に係る金属球検出装置の場合の衝撃緩和構造においては、内部に接続配線３が配置される空隙を有し、一端がセンサー部（１，２）の下部に取り付けられる支持棒２０ｃ３と、この支持棒２０ｃ３の他端に上面が取り付けられると共に下面が滑らかに湾曲した周面を有する略扇形柱状のコマ部２０ｃ２と、このコマ部２０ｃ２を、内面がコマ部２０ｃ２の周面と接触してコマ部２０ｃ２を滑らかに摺動させて収納する内部空間を有する土台２０ｃ１と、を備える。 (Third modification example)
Further, in the impact mitigation structure in the case of the metal ball detection device according to the third modification shown in FIG. 17, there is a gap in which the connection wiring 3 is arranged, and one end is the lower portion of the sensor portions (1, 2). A support rod 20c3 attached to the support rod 20c3, a substantially fan-shaped columnar frame portion 20c2 having a peripheral surface having an upper surface attached to the other end of the support rod 20c3 and a smoothly curved lower surface, and the frame portion 20c2 having an inner surface of the frame portion It is provided with a base 20c1 having an internal space for smoothly sliding and storing the top portion 20c2 in contact with the peripheral surface of the 20c2.

土台２０ｃ１のコマ部２０ｃ２を収納する内部空間は、土台２０ｃ１の上面に開口する孔をなして形成され、開口部３０は、支持棒２０ｃ３の径と略同じ幅で、センサー部（１，２）の主面と直交する方向に延びるように形成されている。すなわち支持棒２０ｃ３は、開口部３０の延びる方向には変位可能であるが、センサー部（１，２）の主面に沿った方向への変位は制限されている。 The internal space for accommodating the top portion 20c2 of the base 20c1 is formed by forming a hole to open on the upper surface of the base 20c1, and the opening 30 has a width substantially the same as the diameter of the support rod 20c3 and the sensor portions (1, 2). It is formed so as to extend in a direction orthogonal to the main surface of the. That is, the support rod 20c3 can be displaced in the extending direction of the opening 30, but the displacement of the sensor portions (1, 2) in the direction along the main surface is limited.

The top portion 20c2 is housed in the base 20c1 so that most of the region of the support rod 20c3 except the vicinity of the connection portion with the top portion 20c2 is exposed to the outside of the opening 30.

また図１８に示すように、土台２０ｃ１、コマ部２０ｃ２及び支持棒２０ｃ３には、接続配線３を収納する空隙が一連に形成されている。また支持棒２０ｃ３、コマ部２０ｃ２及びセンサー部（１，２）からなる一体的な構造体は、下側のコマ部２０ｃ２側に重心が位置するように構成されている。
そのためセンサー部（１，２）が金属球８ａ〜８ｈと衝突した際に、センサー部（１，２）の上端は、コマ部２０ｃ２を中心とした振子状に回動して、金属球８ａ〜８ｈから負荷される衝撃を緩和することができる。また金属球８ａ〜８ｈの通過後、センサー部（１，２）は振子状の動作により、自動的に元の位置に復元する。 Further, as shown in FIG. 18, a series of gaps for accommodating the connection wiring 3 are formed in the base 20c1, the top portion 20c2, and the support rod 20c3. Further, the integrated structure including the support rod 20c3, the top portion 20c2 and the sensor portion (1, 2) is configured so that the center of gravity is located on the lower top portion 20c2 side.
Therefore, when the sensor portions (1, 2) collide with the metal balls 8a to 8h, the upper ends of the sensor portions (1, 2) rotate in a pendulum shape centered on the top portion 20c2, and the metal balls 8a to 8a to The impact applied from 8h can be alleviated. Further, after passing through the metal balls 8a to 8h, the sensor units (1, 2) are automatically restored to their original positions by a pendulum-like operation.

They were arranged along the traveling direction of 8a to 8h, that is, so that the line (radius) connecting the contact point with the metal balls 8a to 8h and the center of the disk 10 and the surface were orthogonal to each other. However, when the impact mitigation structure is used, even if the main surface of the sensor unit (1a, 2a) is arranged so as to intersect the traveling direction of the metal balls 8a to 8h at the time of contact with the metal balls 8a to 8h, there is a problem caused by the impact.
