Description

【0001】
【発明の属する技術分野】
本発明は、パチンコ機の玉整列レール装置における払出玉の不足を検出する装置に関するものである。
【0002】
【従来の技術】
パチンコ機の玉タンクの下方には、玉整列レール装置と玉払出装置が配置されており、玉タンクから複数段二列で供給された玉の流れを、玉整列レール装置により一段一列に整列させて玉払出装置に供給している。ただし玉払出装置が二連式の場合には、当然に玉整列レール装置は二列に玉を整列させて玉払出装置に供給するため、本明細書においては単数列とは玉払出装置の一つの入口に対して玉を一列に供給する状態を意味するものである。
上記の玉整列レール装置は玉タンクから導入した複数段二列の玉の流れを、複数段一列に整列させる上流側整列部と、複数段一列の玉の流れを一段一列の玉列に整列させる下流側整列部とにより構成されるが、玉払出装置により要求された数の玉を安定して払出すために、玉整列レール装置には常に所定量の玉が切れることなく貯留されていることが必要である。
【0003】
しかしながら、玉タンクの供給口に玉がブリッジを形成する等の何らかのトラブルにより玉整列レール装置への玉の供給が停止すると、玉不足を招いて払出しが不可能になるので、早めに玉不足を検出する必要がある。この玉不足を検出するため、従来は玉整列レール装置の下方にセンサーを取り付けていたが、玉整列レール装置の下方のスペースには入賞状態を表示したりする役物等に関連する装置が数多く配置されるので、このスペースは少しでも大きく広げた状態に確保することが必要である。しかしながら、従来は玉不足を検出するセンサーが大きく複雑な構造のものであって、玉整列レール装置の下方のスペースを侵略してスペースを狭いものにしていた。またセンサーの部品点数が多く組み立てに時間を要しコストアップの要因となっていた。
【0004】
【発明が解決しようとする課題】
本発明は上記した従来の問題点を解決し、玉整列レール装置の下方のスペースを大きく確保するとともに、部品点数を減らして簡単に取り付けることのできるパチンコ機の払出し玉不足検出装置を提供するためになされたものである。
【0005】
【課題を解決するための手段】
上記の課題を解決するためになされた本発明の払出玉不足検出装置は、玉タンクから導入して主流玉列と副流玉列の複数段二列とした玉の流れを、上流側整列部において副流玉列が主流玉列より高くなるように底面を主流玉列側に向けて低く傾斜させて複数段一列に整列させ、下流側整列部において一段一列に整列させる玉整列レール装置に設けられるパチンコ機の払出玉不足検出装置において、
前記副流玉列の底面に細幅の長穴を設け、一端が軸支され他端が上向きに付勢された玉検出レバーを副流玉列の底面裏側に配置して、その上端を前記長穴から突出させて副流玉列によって押し下げ可能なものとするとともに、玉検出レバーの押し下げにより光ビームが遮断されて玉の存在を検出し、玉検出レバーの上昇により光ビームが透過して玉不足を検出する光電スイッチを、副流玉列の底面裏側に配置して、これらの玉検出レバーおよび光電スイッチを装置カバーで覆ったうえに
玉検出レバーには、前記長穴から侵入する塵埃を受け止めるための樋状部を設け、この樋状部の下方の前記装置カバーには、侵入した塵埃を排出するための塵埃排出穴を設けたことを特徴とするものである。
【0006】
上記した発明において、樋状部を、光電スイッチの投光側と受光側の上方を覆う長さとして、一端に向けて低く傾斜されたものとしたうえに、その低位側端部下方の装置カバーに塵埃排出穴を設けることができる。また、玉整列レール装置の上流側整列部に中央隔壁を配置して、上流側整列部を中央隔壁を介して左右対称に二連式の構造とすることができる。
【0007】
本発明のパチンコ機の払出玉不足検出装置は、上流側整列部において主流玉列より高い位置に形成された副流玉列の裏側に取付けることにより取付け位置を従来より上方にして、玉整列レール装置の下方のスペースを大きく確保するとともに、部品点数を減らして簡単な構造で玉不足を検出することができる。
【0008】
【発明の実施の形態】
以下に図面を参照しつつ本発明の好ましい実施形態を示す。
図1は本発明の払出玉不足検出装置を備えたパチンコ機の裏面を示す正面図であり、1は玉タンク、2はその下方に配置された玉整列レール装置、3は玉整列レール装置の下方に付設された本発明の払出玉不足検出装置、4は玉減速誘導通路、5は玉払出装置である。この例では玉払出装置5は賞玉と貸玉とをそれぞれ払出すことができるように二連式となっている。玉タンク1は端部の玉供給孔から玉を複数段二列の状態で下方の玉整列レール装置2に導入する。
【0009】
この例では玉タンク1はセット板6に片持構造で支持されており、使用状態においては図示していない受け枠にクランプ機構7、7により固定できるようになっている。また、玉整列レール装置2は図面上の左端を玉タンク1から垂下する保持機構8により保持され、図面上の右端を玉減速誘導通路4に差し込むことによって支持されており、この玉整列レール装置は上流側整列部9と下流側整列部17とにより構成されている。
【0010】
図2〜図3は本発明の払出玉不足検出装置3を備えた玉整列レール装置2の上流側整列部9の平面図と垂直断面図であり、図4は図2のA−A断面図である。上流側整列部9は二連式の玉払出装置5に対応させて中央隔壁10を介して左右対称に形成され、払出玉不足検出装置3も左右にそれぞれ二連式に設けられているが、以下にその片側のみについて説明する。
【0011】
上流側整列部9は、玉の入側においては主流玉列と副流玉列の二列の玉列を収容可能な幅員に形成されており外側に副流玉列の案内側壁11が形成されている。15は最下段の主流玉列を一線上に保持する溝状の案内手段で、主流玉列の底面16は、図3に示すように下流へ向けて低く傾斜しているが、副流玉列の底面12は下流側において主流玉列より高くなるように傾斜させるとともに、図4に示すように副流玉列が主流玉列より高くなるように主流玉列側に向けて低く傾斜させてある。このため、副流玉列の底面12上の玉は下流側に移動するにつれて自然に主流側に流入し一列になるが、複数段のままであり、次の下流側整列部17において一段一列にされて玉減速誘導通路4に流入する。
【0012】
玉タンク1の玉供給孔に近い側の副流玉列の底面12には主流玉列の流下する方向に平行に、すなわち案内手段15に平行に細幅の長穴14が設けられ玉検出レバー25の上端が副流玉列の底面12より突出できるものとしてある。
【0013】
本発明の払出玉不足検出装置3は、図3〜図4に示すように副流玉列の底面の裏側に一端が支軸21により支持され、他端がばね22の反発力により跳ね上がり上端が長穴14から突出することが可能で、下向きに突き出た光遮断片24を有する玉検出レバー25と、玉検出レバー25の下方に配置されその位置を検出する検出装置26とにより構成される。ここで検出装置26は投光側と受光側とからなる光電スイッチであり、該光電スイッチはコネクター付きのスナップフィットタイプのもので玉整列レール装置2と一体に成形された検出装置係止片29に差し込み式で取付けられている。
【0014】
上流側整列部9の長穴14上に玉が存在する時は検出レバー25の上端が玉により押し下げられ、検出装置26の投光側と受光側との間の間隙に光遮断片24が降下して光ビームを遮ることにより、玉の存在が確認される。ここで、光遮断片24は検出レバー25に対し直角に設けられているが、光遮断片24の設置角度は検出装置26の取付け方向によって決まるものであり、投光側と受光側との間の間隙が玉検出レバーと平行である時は光遮断片24は検出レバー25に対し平行に設けることができる。
【0015】
何らかの理由により玉タンク1からの玉の供給が停止されて長穴14上において玉が不足した時は、図5〜図6に示すようにばね22の反発力により玉検出レバー25が跳ね上がって、玉検出レバー25の上端が長穴14から突出するとともに、光遮断片24が検出装置26の投光側と受光側との間の隙間より退却して光ビームを透過することによって、払出玉不足を検出することができる。
【0016】
検出レバー25の光遮断片24の上部には、図3および図7に示すように検出装置26の投光側と受光側を完全に覆う長さで、且つ底面がばね22側に向けて低く傾斜された集塵用樋状部28が設けられ、その傾斜終端部の装置カバー27の下面には塵埃排出穴31が設けられて、検出装置26の投光側と受光側の間の隙間にゴミが入らぬようにするとともに、侵入した塵埃を排出できるような構造としてある。
【0017】
払出玉不足検出装置3の取付けを簡単にし部品点数を削減するために、図8〜図9に示すように玉検出レバー25を取り付ける支軸21および装置カバー27を取り付ける装置カバー係止片30は、前記した検出装置係止片29とともに玉整列レール装置2と一体に成形されている。
【0018】
本発明のパチンコ機の払出玉不足検出装置は、上流側整列部において主流玉列より高い位置に形成された副流玉列の裏側に取付けることにより取付け位置を従来より上方にして、玉整列レール装置の下方のスペースを大きく確保するとともに、部品点数を減らして簡単な構造で玉不足を検出することができる。
【0019】
【発明の効果】
以上に説明したように、本発明の払出玉不足検出装置は、底面位置が主流玉列より高い副流玉列の下側に付設したことにより玉整列レール装置の下方のスペースを広く取ることができる。検出装置として簡単で小さく取付けの容易なスナップタイプの光電スイッチを用いたことによりプリント基板を必要とせず装置の組み立てが簡単にできる。さらに取付け部品を玉整列レール装置と一体に成形したことにより部品点数を削減しコストの低減を図ることができる等の利点がある。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing the back side of a pachinko machine equipped with a payout ball shortage detecting device of the present invention, wherein 1 is a ball tank, 2 is a ball alignment rail device arranged below the ball tank, and 3 is a ball alignment rail device. A payout ball shortage detecting device according to the present invention attached below, 4 is a ball deceleration guide passage, and 5 is a ball payout device. In this example, the ball dispensing device 5 is of a double type so that a prize ball and a lending ball can each be dispensed. The ball tank 1 introduces balls from the ball supply holes at the end into the lower ball alignment rail device 2 in a state of multiple rows and two rows.
[0009]
In this example, the ball tank 1 is supported by a set plate 6 in a cantilever structure, and can be fixed to a receiving frame (not shown) by clamp mechanisms 7 and 7 in use. The ball alignment rail device 2 is supported by a holding mechanism 8 that hangs down from the ball tank 1 at the left end in the drawing, and is supported by inserting the right end in the drawing into the ball deceleration guide passage 4. Is composed of an upstream alignment portion 9 and a downstream alignment portion 17.
[0010]
2 to 3 are a plan view and a vertical sectional view of the upstream side alignment portion 9 of the ball alignment rail device 2 provided with the payout ball shortage detecting device 3 of the present invention, and FIG. 4 is a sectional view taken along the line AA in FIG. It is. The upstream side alignment portion 9 is formed symmetrically via the central partition 10 in correspondence with the double ball delivery device 5, and the payout ball shortage detection device 3 is also provided in a duplex manner on each side. Only one side will be described below.
[0011]
The upstream side alignment portion 9 is formed in a width that can accommodate two rows of mainstream and secondary flow ball rows on the ball entry side, and a guide side wall 11 of the secondary flow ball row is formed on the outside. ing. Reference numeral 15 denotes a groove-shaped guide means for holding the lowermost mainstream ball row in a single line, and the bottom surface 16 of the mainstream ball row is inclined downward toward the downstream as shown in FIG. The bottom surface 12 is inclined so as to be higher than the mainstream ball row on the downstream side, and is inclined lower toward the mainstream ball row side so that the secondary flow ball row is higher than the mainstream ball row as shown in FIG. . For this reason, the balls on the bottom surface 12 of the secondary flow ball row naturally flow into the main flow side as they move to the downstream side and become one row. And flows into the ball deceleration guide passage 4.
[0012]
The bottom surface 12 of the secondary flow ball row on the side close to the ball supply hole of the ball tank 1 is provided with a narrow long hole 14 parallel to the flow direction of the main flow ball row, that is, parallel to the guide means 15, and a ball detection lever. It is assumed that the upper end of 25 can protrude from the bottom surface 12 of the side flow ball row.
[0013]
As shown in FIGS. 3 to 4, the payout ball shortage detecting device 3 of the present invention has one end supported by a support shaft 21 on the back side of the bottom surface of the secondary flow ball array, and the other end springs up due to the repulsive force of the spring 22. The ball detection lever 25 can project from the elongated hole 14 and has a light blocking piece 24 protruding downward, and a detection device 26 that is disposed below the ball detection lever 25 and detects its position. Here, the detection device 26 is a photoelectric switch composed of a light projecting side and a light receiving side. The photoelectric switch is a snap-fit type with a connector and is a detection device locking piece 29 formed integrally with the ball alignment rail device 2. Installed in a plug-in.

The upper end of the detection lever 25 is found pressed down by the ball when the ball on the elongated hole 14 of the upstream-side alignment unit 9 is present, the light blocking arm 24 into the gap between the light projection side of the detection device 26 and the light receiving side The presence of the ball is confirmed by descending and blocking the light beam. Here, although the light blocking piece 24 is provided at a right angle to the detection lever 25, the installation angle of the light blocking piece 24 is determined by the mounting direction of the detection device 26, and is between the light projecting side and the light receiving side. When the gap is parallel to the ball detection lever, the light shielding piece 24 can be provided parallel to the detection lever 25.
[0015]
When the supply of balls from the ball tank 1 is stopped for some reason and there is a shortage of balls on the long hole 14, the ball detection lever 25 jumps up due to the repulsive force of the spring 22, as shown in FIGS. The upper end of the ball detection lever 25 protrudes from the long hole 14, and the light blocking piece 24 retreats from the gap between the light projecting side and the light receiving side of the detecting device 26 and transmits the light beam, so that the payout ball is insufficient. Can be detected.
