【０００６】
【作用】
請求項１に記載のパチンコ機における球切れ検出装置によれば、裏側に貯留されているパチンコ球が漸減する状況のもとで、球タンク内の貯留球が無くなって球レールの上流端部内の貯留球が減少すると、まず、第１球切れ作動片が、球受部で受ける球圧（球重量）から解放されて２個の球切れ検出スイッチにおける上向きの付勢力により上傾変化されて球切れ状態とされるとともに、これに追従して係動片が引上げられて２個の球切れ検出スイッチの触動片をともに解放する。これにより各球切れ検出スイッチは、個々の触動片が付勢力により上傾復帰されることにより「球切れ検出状態」として検出信号を発生する。そしてこの各検出信号が、スイッチ基板とコネクタそして中継基板を介して、賞品球切れ表示ランプに対する点灯用信号、遊技場の管理装置に対する球切れ信号として出力されることに伴い、表示ランプが点灯表示され、また管理装置の制御による球補給作動が適時開始されて供給された新たなパチンコ球が球タンク内に投入（補充）される。
次いで、前記球レールの上流端部内の球無し（球切れ）に続いて球レールの上流部内の貯留球が減少（一般的には、球補給作動の一時的な遅れに起因する球タンクへの球投入不足と賞品球払い出しとによる減少）すると、前記第１球切れ作動片の下流部に位置する第２球切れ作動片が、球受部で受ける球圧（球重量）から解放されて上向きの付勢力により上傾変化されて球切れ状態とされる。これに追従して伝動機構が球切れ状態に連動されることにより、球送り機構におけるシャッタが球受口に対する閉鎖状態（球通し不能状態）に拘束保持される。これにより、遊技用パチンコ球の球発射起点への送込み（球送り）が停止されて打球発射が暫時不能停止される。
【０００７】
前述したような球切れ状態検出をなす請求項１の装置において、前記第１球切れ作動片に関連付けられたスイッチ検出部に何らかの不具合が発生した場合には、前枠部の裏側での作業体勢において、前記球レール内のパチンコ球の有無に拘わらず前記係動片を押上げて２個の球切れ検出スイッチの触動片を解放したもとで、裏枠の基板収納部に支持されているスイッチ基板を引抜くように取外す。
【０００８】
請求項２に記載のパチンコ機の球切れ検出装置によれば、球タンク内の貯留球が無くなって球レールの上端部内の貯留球が減少すると、球切れ作動片が、球受部で受ける球圧（球重量）から解放されて２個の球切れ検出スイッチにおける上向き付勢力により上傾変化されて球切れ状態に変動されるとともに、これに追従して係動片が引上げられて２個の球切れ検出スイッチの触動片をともに解放する。これにより、各球切れ検出スイッチは、個々の触動片が付勢力により上傾復帰されることにより「球切れ検出状態」として検出信号を発生する。そして、この各検出信号が、スイッチ基板とコネクタそして中継基板を介して、賞品球切れ表示ランプに対する点灯用信号、遊技場の管理装置に対する球切れ信号として出力されることに伴い、表示ランプが点灯表示されて球切れ状態が報知され、また管理装置の制御による球補給作動が適時開始されて供給された新たなパチンコ球が球タンク内に投入（補充）される。
【０００９】
前述したような球切れ状態を検出する請求項２の装置において、前記球切れ作動片に関連付けられたスイッチ検出部側に何らかの不具合が発生した場合には、前枠部の裏側での作業体勢において、前記球レール内のパチンコ球の有無に拘わらず前記係動片を押上げて２個の球切れ検出スイッチの触動片を解放し、このもとで、裏枠の基板収納部に支持されているスイッチ基板を引抜くよう取外す。
【００１０】
【発明の効果】
請求項１に記載のパチンコ機の球切れ検出装置によれば、球タンク下方の球レール内の貯留パチンコ球が減少した場合には、第１球切れ作動片が球圧から解放されて球切れ状態に変位されることに従い、係動片が上動して２個の球切れ検出スイッチの触動片をともに解放する。これにより各球切れ検出スイッチは、「球切れ検出状態」として検出信号を発生し、この各検出信号が、スイッチ基板およびコネクタを介して賞品球切れ表示ランプの点灯用信号、遊技場の管理装置の球切れ信号として入力される。これに伴い、表示ランプが点灯表示されて「球切れ状態」を報知することができ、また管理装置の制御による球補給作動が適時開始されて球タンクに新たなパチンコ球を補給することができる。
また、これより少し時間経過した後に前記球レールの上流部内の貯留パチンコ球が減少した場合には、前記第１球切れ作動片の下流部に位置する第２球切れ作動片が球圧から解放されて球切れ状態に変位される。これに追従して伝動機構が球切れ状態に連動されることにより、球送り機構におけるシャッタが、球受口に対する球通し不能な閉鎖状態に拘束保持される。これにより遊技用パチンコ球の球発射起点への送込み（球送り）を停止させて打球発射を暫時不能停止することができる。
【００１１】
さらに、請求項１に記載のパチンコ機の球切れ検出装置では、前記第１球切れ作動片に関連付けられたスイッチ検出部に何らかの不具合が発生した場合には、前枠部の裏側での作業体勢において、係動片を押上げて２個の球切れ検出スイッチの触動片を解放したもとで、裏枠の基板収納部に支持されているスイッチ基板を引抜くだけの単純な作業で球切れ検出スイッチを簡単に取外し、交換・修理することができる。
【００１２】
請求項２に記載のパチンコ機の球切れ検出装置によれば、球タンク下方の球レール内の貯留パチンコ球が減少した場合には、球切れ作動片が球圧から解放されて球切れ状態に変位されることに従い、係動片が上動して２個の球切れ検出スイッチの触動片をともに解放する。これにより各球切れ検出スイッチは、「球切れ検出状態」として検出信号を発生し、この各検出信号が、スイッチ基板およびコネクタを介して賞品球切れ表示ランプの点灯用信号、遊技場の管理装置の球切れ信号として出力されることに伴い、表示ランプが点灯表示されて「球切れ状態」を報知することができ、また管理装置の制御による球補給作動が適時開始されて球タンクに新たなパチンコ球を補給することができる。
また、請求項２に記載のパチンコ機の球切れ検出装置では、前記球切れ作動片に関連付けられたスイッチ検出部に何らかの不具合が発生した場合には、前枠部の裏側での作業体勢において、係動片を押上げて２個の球切れ検出スイッチの触動片を解放したもとで、裏枠の基板収納部に支持されているスイッチ基板を引抜くだけの単純な作業で球切れ検出スイッチを簡単に取外し、交換・修理することができる。

【００２９】
球レール１８には賞品球払い出しユニット１９側に向かって先下り状に傾斜した底板１８ａと、この底板１８ａの後端縁に連接されて垂立された縦壁板１８ｂとが形成され、底板１８ａの基端部付近には球タンク１７の球出口１７ｅの直下に配設されて補給用のパチンコ球群が集合する球補給部２５が開設され、縦壁板１８ｂの基端部付近の前面には金属薄板若しくは金属箔板によって形成されてアース用のリード線が接続された静電気防止用の帯電防止板４２が重ね合わされて固定されている。
【００３０】
帯電防止板４２には球レール１８内の基端部付近を後方から透視するための透視窓４２ａが開設されている。
【００３１】
球レール１８の球補給部２５側には、図４，５に示すように該球レール１８の上端外に挿着された支軸２２によって片持ち状態で上下方向への揺動可能に支持されて球レール１８の上端内に延出した球受部の内端下部に挿通孔２０aが貫設された第１球切れ作動片２０と、この第１球切れ作動片２０の内方（図示右方の下流側）で球レール１８に突設された支軸２３によって片持ち状態で上下方向への揺動可能に支持され、第１球切れ作動片２０の球受部の長さより延長された長さを有する球受部２１aが形成された第２球切れ作動片２１とが、球補給部２５の開口底面を閉塞した状態で互いに逆向き位置に隣合って直列状に配置されている。両球切れ作動片２０，２１は第１球切れ作動片２０上のパチンコ球がその自重で第２球切れ作動片２１の球受部２１ａ上へ転落するように配列されている。第１球切れ作動片２０はその球受面の面積が４cm2未満となるように形成され、第２球切れ作動片２１はその球受面の面積が１２cm2未満となるように形成されている。

第２の中継部材３６には帯板状に基片３６ａと、この基片３６ａの基端部に連接されて軸部３９が嵌挿された円筒状の軸挿部３６ｂと、基片３６ａの先端部に連接されて第３の中継部材４０の後端部が掛止された掛止部３６ｃと、軸挿部３６ｂの内方位置で基片３６ａに連接されて連繋片３３の、前連繋部３３ｂが脱出可能で連動可能に係合された係合部３６ｄとが形成されている。
【００５４】
第２の中継部材３６の係合部３６ｄには裏枠１６が第１の中継部材３１とともに前回動端へ回動したときに連繋片３３の前連繋部３３ｂが挿通される丸孔状の挿通孔３７が形成されるとともに、係合部３６ｄには、挿通孔３７の後側に挿通孔３７を包用するように隣設されて断面積が後方から前方へ漸減するすりばち面状の凹曲面形状を有し、連繋片３３の前連繋部３３ｂが挿通孔３７に挿通される直前に連繋片３３の先端部を連繋片３３の上下方向の全移動範囲にわたって滑動させて挿通孔３７側へ案内する案内面３８が形成されている。
【００５５】
案内面３８の前端縁は丸孔状で挿通孔３７の後側孔縁に連接され、案内面３８の後端縁は連繋片３３の上下方向の移動距離より拡大された長径部を有する縦長の楕円形状に形成され、案内面３８の上部には上方へ移動した連繋片３３を案内する上案内部３８ａが形成され、案内面３８の下部には下方へ移動した連繋片３３を案内する下案内部３８ｂが形成されている。

【００５７】
両球切れ作動片２０，２１上のパチンコ球が限度以下に減少して第１球切れ作動片２０が上方へ揺動し、続いて、第２球切れ作動片２１の球受部２１ａが上方へ揺動すると、第１の中継部材３１の連繋杆３２が上動して連繋片３３が上方へ変位し、第２の中継部材３６が上方へ揺動して第３の中継部材４０が引上げられ、シャッタ１４の受動部１４ａが第３の中継部材４０によって押上げられることにより、図２のようにシャッタ１４が実線で示される通常の球送り可能位置から想像線で示される球送り不能位置に回動変化してその球止め部１４bで球受口１０を遮断し、球発射起点５へのパチンコ球の供給を不能とする。
【００５８】
続いて、上記した構成を有する実施例の作用と効果を説明する。
本例では補給用のパチンコ球が集合する球補給部２５にはそれぞれパチンコ球の受止めおよび誘導が可能で受止めたパチンコ球の個数が限度以下に減少したときに個々に作動する第１球切れ作動片２０と第２球切れ作動片２１とを設置し、第１球切れ作動片２０をこの第１球切れ作動片２０の動きによって球切れ信号を出力する１対の球切れ検出スイッチ２８に連繋し、第２球切れ作動片２１をこの第２球切れ作動片２０の動きによって作動する第１の中継部材３１に連繋し、両球切れ作動片２０，２１を、第１球切れ作動片２０上のパチンコ球の個数が限度以下に減少して第１球切れ作動片２０が作動した後で、第２球切れ作動片２１上のパチンコ球の個数が限度以下に減少して第２球切れ作動片２１が作動するように配列してある。
【００５９】
このため、球補給部２５での球切れ発生状況を両球切れ作動片２０，２１によって重複して感知して複数の他部材に伝達することができるので、球切れに対処する処理態様を多様化することができる。
【００６０】
また、球補給部２５での球切れを検出する部材を、球切れ検出スイッチ２８に連繋された第１球切れ作動片２０と、伝動機構に連繋された第２球切れ作動片２１とに分割して両球切れ作動片２０，２１の動きを球切れ検出スイッチ２８および第１の中継部材３１に対して個別に伝えることができるので、検出スイッチおよび伝動機構をそれぞれ適正な態様で相互干渉を無くして的確に作動させることができ、球切れ検出機構の誤動作や検出ミスを防止することができる。
【００６１】
さらに、球切れを両球切れ作動片２０，２１によって時間的にずらせて検出することができるので、球切れ状態のレベルに合わせてパチンコ機の機能を段階的に切替えて球切れに２段階で対処することができる。
【００６２】
また、球切れ時に第１球切れ作動片２０の動きによって２つの球切れ検出スイッチ２８を同時に作動させることができ、両球切れ検出スイッチ２８の触動片２８ａの動作タイミングがずれるおそれがないので、球切れ検出制御回路を簡略化してそのコストを節減することができるとともに、２つの異なった場所へ同時に球切れ信号を出力することができる。
【００６３】
さらに、球送り機構８の機能を停止する以前に球切れ検出スイッチ２８が球切れ信号を出力するので、パチンコ機の機能が停止する以前に警告表示等の球切れに対する予防処置を行うことが可能となり、また、球送り機構８の機能を停止する以前に遊技場の管理装置に球切れ信号を出力することができるので、球切れが発生した場合の処置を予め準備することができる。
【００６４】
また、球切れ検出スイッチ２８が出力する球切れ信号を当該パチンコ機の制御回路に送ると、球切れ信号を、賞品球を払い出す賞品球払い出しモータの電源や、打球用の発射モータの電源等を断つための制御手段として活用することができる。
【００６５】
さらに、両球切れ作動片２０，２１の球受け面を横方向に隣接して配列してあるので、両球切れ作動片２０，２１が作動するタイミングを一定範囲内で接近させてそのタイミングのずれを短縮することができる。
【００６６】
また、第２球切れ作動片２１を、パチンコ球の流れに関して第１球切れ作動片２０の下流に配置して流下するパチンコ球を待機する位置に設置し、第２球切れ作動片２１の動きが第１球切れ作動片２０上から第２球切れ作動片２１上へ転動するパチンコ球の流れを妨げることが無いので、両球切れ作動片２０，２１の作動領域での球詰りを防ぐことができる。
【００６７】
さらに、２つの球切れ検出スイッチ２８が球切れ表示ランプや管理装置に同種の信号を並行的に出力し、一方の球切れ検出スイッチ２８に断線や異常が発生しても、球切れ検出信号の取り出しが中断するおそれがないので、球切れ検出を補償して球切れ検出信号の発信ミスを無くすことができる。
【００６８】
また、第１球切れ作動片２０の球受面が球補給部２５で占めるスペースを４cm²未満とし、第２球切れ作動片２１の球受面が球補給部２５で占めるスペースを１２cm²未満としてあるので、両球切れ作動片２０，２１がパチンコ球の貯留や流れに及ぼす影響を可及的に軽減することができる。
【００６９】
さらに、第２球切れ作動片２１の球受部２１ａの上面に球分離整列用の凸条２７ｄを形成してあるので、球タンク１７内から流下するパチンコ球群を前後方向に分離させて整列状態にして球レール１８へ誘導することができる。
【００７０】
また、両球切れ作動片２０，２１がパチンコ球の流れの方向に沿って配列され、球補給部２５での単一箇所における局部的な球切れ検出が行われないので、球補給部２５の全領域でのパチンコ球の貯留状態や球切れ状態を平均的に偏りなく検出することができる。
【００７１】
さらに、単一の部材の動きを球切れ検出スイッチ２８と伝動機構とに同時に伝える構成ではないので、伝動機構の動きが球切れ検出スイッチ２８に逆戻り状に作用して球切れ検出スイッチ２８が誤動作したり、再作動する不具合を無くすことができる。
【００７２】
また、両球切れ動片２０，２１の動きが時間的にずれるので、球切れに際して予備的な処置と、応急的な処置とを時間的に異らせて別個に行うことができる。

According to the ball breakage detecting device in the pachinko machine according to claim 1, in the situation where the pachinko balls stored on the back side gradually decrease, the stored balls in the ball tank disappear and the ball ends in the upstream end of the ball rail. When the number of stored balls decreases, first, the first ball breaker operating piece is released from the ball pressure (ball weight) received by the ball receiver and is tilted upward by the upward biasing force in the two ball breaker detection switches. In addition to being in a cut state, the engaging piece is pulled up following this to release the two touching pieces of the ball break detecting switch. As a result, each ball break detection switch generates a detection signal as a “ball break detection state” when the individual touching piece is returned to the upper position by the biasing force. Each of the detection signals is output as a lighting signal for a prize ball out display lamp and a ball out signal for a game management device via a switch board, a connector and a relay board. In addition, the ball replenishing operation under the control of the management device is started in a timely manner, and a new pachinko ball that has been supplied is introduced (supplemented) into the ball tank.
Then, following the absence of a ball (out of the ball) in the upstream end portion of the ball rail, the number of stored balls in the upstream portion of the ball rail decreases (generally, the ball tank is caused by a temporary delay in the ball supply operation). 2) The second ball-cutting piece located downstream of the first ball-cutting piece is released from the ball pressure (ball weight) received by the ball-receiving part and moves upward. The ball is cut upward by the urging force of. Following this, the transmission mechanism is interlocked with the ball-out state, whereby the shutter in the ball-feeding mechanism is constrained and held in a closed state (a state in which the ball cannot pass) with respect to the ball receiving port. Thereby, the feeding (ball feeding) of the game pachinko ball to the ball launch starting point is stopped, and the hitting of the hit ball is stopped for a while.

According to the ball breakage detecting device for a pachinko machine according to claim 2, when the stored ball in the ball tank disappears and the stored ball in the upper end of the ball rail decreases, the ball breakage operation piece receives the ball received by the ball receiving portion. The pressure is released from the pressure (ball weight) and the upward biasing force of the two ball breakage detection switches is changed upward to change the ball into a ball breakage state. Release the touching piece of the ball break detection switch together. As a result, each ball break detection switch generates a detection signal as a “ball break detection state” when the individual touching piece is returned to the upper position by the biasing force. Then, each of the detection signals is output as a lighting signal for a prize ball out display lamp and a ball out signal for a game management device via a switch board, a connector, and a relay board. The ball breakage state is displayed to notify the ball, and the ball replenishment operation under the control of the management device is started in a timely manner, and a new pachinko ball supplied is introduced (replenished) into the ball tank.

[0058]
Subsequently, the operation and effect of the embodiment having the above-described configuration will be described.
In this example, the ball supply unit 25 in which replenishment pachinko balls gather can receive and guide the pachinko balls, respectively, and the first ball that operates individually when the number of received pachinko balls decreases below the limit. A pair of ball breakage detection switches 28 are provided which are provided with a piece breakage operation piece 20 and a second ball breakage operation piece 21, and which outputs a ball breakage signal by the movement of the first ball breakage operation piece 20. Are connected to the first relay member 31 that is actuated by the movement of the second ball-cutting operation piece 20, and the two ball-cutting operation pieces 20, 21 are connected to the first ball-cutting operation. After the number of pachinko spheres on the piece 20 is reduced below the limit and the first ball break working piece 20 is activated, the number of pachinko balls on the second piece 20 is reduced below the limit and the second The ball break working pieces 21 are arranged so as to be actuated.
[0059]
For this reason, since the ball breakage occurrence state in the ball replenishment unit 25 can be detected by both the ball break working pieces 20 and 21 and transmitted to a plurality of other members, a variety of processing modes for dealing with the ball breakage are various. Can be
[0060]
Further, the member for detecting the ball breakage in the ball supply unit 25 is divided into a first ball break working piece 20 linked to the ball break detecting switch 28 and a second ball break working piece 21 linked to the transmission mechanism. Since the movements of both the ball break operating pieces 20 and 21 can be individually transmitted to the ball break detection switch 28 and the first relay member 31, the detection switch and the transmission mechanism can each interfere with each other in an appropriate manner. It is possible to operate without any loss, and it is possible to prevent malfunction or detection error of the ball breakage detection mechanism.
[0061]
Furthermore, since the ball breakage can be detected by shifting both the ball breakage operation pieces 20 and 21 in time, the function of the pachinko machine is switched step by step in accordance with the level of the ball breakage state in two steps. Can be dealt with.
[0062]
In addition, since the two ball break detection switches 28 can be operated simultaneously by the movement of the first ball break operation piece 20 at the time of the ball break, there is no possibility that the operation timing of the touching piece 28a of the both ball break detection switches 28 is shifted. The ball break detection control circuit can be simplified to reduce the cost, and the ball break signal can be output simultaneously to two different locations.
[0063]
Furthermore, since the ball break detection switch 28 outputs a ball break signal before stopping the function of the ball feeding mechanism 8, it is possible to take preventive measures against the ball break such as a warning display before the pachinko machine function stops. In addition, since a ball break signal can be output to the game hall management device before the function of the ball feeding mechanism 8 is stopped, it is possible to prepare in advance a treatment when a ball break occurs.
[0064]
Further, when the ball break signal output from the ball break detection switch 28 is sent to the control circuit of the pachinko machine, the ball break signal is sent to the power supply of the prize ball payout motor for delivering the prize ball, the power supply of the launch motor for hitting the ball, etc. It can be utilized as a control means for cutting off.
[0065]
Further, since the ball receiving surfaces of both the ball break working pieces 20 and 21 are arranged adjacent to each other in the lateral direction, the timing at which both ball break working pieces 20 and 21 are actuated is brought close within a certain range and The shift can be shortened.
[0066]
Further, the second ball-cutting operation piece 21 is installed at a position waiting for the pachinko ball flowing down by being arranged downstream of the first ball-cutting operation piece 20 with respect to the flow of the pachinko ball. Does not hinder the flow of the pachinko sphere rolling from the first ball-cutting piece 20 to the second ball-cutting piece 21, thus preventing ball clogging in the operating region of both the ball-cutting pieces 20, 21. be able to.
[0067]
Further, the two ball break detection switches 28 output the same kind of signal to the ball break display lamp and the management device in parallel, and even if one of the ball break detection switches 28 is disconnected or malfunctioned, Since there is no possibility that the take-out will be interrupted, it is possible to compensate for the detection of a broken ball and eliminate a mistake in transmitting a broken ball detection signal.
[0068]
Further, the space occupied by the ball receiving surface of the first ball break working piece 20 by the ball supply unit 25 is 4 cm.²The space occupied by the ball receiving surface of the second ball-cutting piece 21 by the ball supply unit 25 is 12 cm.²Therefore, it is possible to reduce as much as possible the influence of the two-ball piece operating pieces 20 and 21 on the accumulation and flow of pachinko balls.
[0069]
Furthermore, since the protrusion 27d for ball separation / alignment is formed on the upper surface of the ball receiving portion 21a of the second ball break working piece 21, the pachinko ball group flowing down from the ball tank 17 is separated in the front-rear direction and aligned. The state can be guided to the ball rail 18.
[0070]
In addition, since both the ball break working pieces 20 and 21 are arranged along the flow direction of the pachinko sphere, and the local ball break detection is not performed at a single location in the ball refill unit 25, It is possible to detect, on an average, a pachinko ball storage state and a ball-out state in all regions.
[0071]
Further, since the movement of a single member is not transmitted to the ball breakage detection switch 28 and the transmission mechanism at the same time, the movement of the transmission mechanism acts on the ball breakage detection switch 28 in a reverse direction so that the ball breakage detection switch 28 malfunctions. And the trouble of re-operation can be eliminated.
[0072]
In addition, since the movements of both the ball piece moving pieces 20 and 21 are shifted in time, it is possible to perform the preliminary treatment and the emergency treatment separately at different times in the event of a ball break.
