Abstract

<P>PROBLEM TO BE SOLVED: To prevent the swallowing, clogging and erroneous exclusion of tokens by making the tokens to pass through pass through and surely excluding the tokens to be excluded no matter in which state a token path is switched to a token fetch side and a token exclusion side without being affected by the speed of the tokens and the switching timing of an operation when inputting a start switch or the like. <P>SOLUTION: This fed token sorting device is provided with a temporary withdrawal means for temporarily withdrawing an exclusion guide member from the token path so as not to suddenly increase the passing resistance of the medal when the exclusion guide member erroneously touches the token to pass through and gives the passing resistance in the case of sorting the token by fetching or excluding the token fed to a game machine. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

この発明は、例えばスロットマシンなどの遊技機に使用されるようなメダルを選別する投入メダル選別装置に関し、さらに詳しくはメダル選別部でのメダルの詰りを確実に防止する投入メダル選別装置及び遊技機に関する。   The present invention relates to an inserted medal sorting device that sorts medals used in a gaming machine such as a slot machine, and more specifically, an inserted medal sorting device and a gaming machine that reliably prevent clogging of medals at a medal sorting unit. About.

通常、スロットマシンに内蔵される投入メダル選別装置(メダルセレクタ)は、先行出願の特許文献1にも開示されているように、制御部の判定によってメダルの受入可否を管理しており、該制御部がメダルの受入れを許可している場合は、投入口より投入されたメダルを外形等により正規のメダルと、偽メダルとに選別している。   Usually, the inserted medal sorting device (medal selector) built in the slot machine manages whether or not to accept medals based on the determination of the control unit as disclosed in Patent Document 1 of the prior application. When the department permits the acceptance of medals, the medals inserted from the insertion slot are sorted into regular medals and fake medals according to the outer shape and the like.

このとき、正規のメダルは検知センサにより、その通過枚数を計数し、スロットマシン内に取込まれる。これに対し、偽メダルは枚数を計数することなく、メダル通路より排除される。   At this time, the regular medals are counted by the detection sensor and taken into the slot machine. On the other hand, false medals are excluded from the medal passage without counting the number of sheets.

一方、制御部がメダルの受入れを拒否している場合は、メダル通路を変更すると共に、メダル通路に流下してきたメダルを流下規制する規制レバーを突出させることで、スロットマシン内へのメダルの取込みを防止している。   On the other hand, when the control unit refuses to accept medals, the medal passage is changed, and the control lever that restricts the flow of medals flowing down to the medal passage is protruded, so that the medal can be taken into the slot machine. Is preventing.

ここで、メダルの受入れを拒否する条件としては、クレジットの最大貯留枚数を超えている場合と、ゲームを開始させるスタートスイッチの押下により、ゲームが既に開始された場合である。   Here, the conditions for refusing acceptance of medals are when the maximum number of stored credits is exceeded and when the game is already started by pressing the start switch for starting the game.

一般に、スロットマシンなどの遊技機の制御において、スタートスイッチの操作は、検知センサが遊技に必要とするメダル枚数の通過を計数した時点で有効となる。そして、ゲームが開始されると不正行為を防ぐなどのために前記検知センサは無効化される。さらに、検知センサがメダルを検知している場合(例えば図19(B)の領域A参照)においても、スタートスイッチの操作は無効化される。また、不正防止のため、図15に示すように、上流側と下流側の2つの検知センサS11,S12の光軸の配置間隔Lsを適正なメダルの直径φDよりも小さくなるように配置している。   In general, in the control of a gaming machine such as a slot machine, the operation of the start switch is effective when the detection sensor counts the number of medals required for the game. Then, when the game is started, the detection sensor is invalidated to prevent fraud. Further, even when the detection sensor detects a medal (see, for example, the area A in FIG. 19B), the operation of the start switch is invalidated. In order to prevent fraud, as shown in FIG. 15, the arrangement interval Ls of the optical axes of the two detection sensors S11 and S12 on the upstream side and the downstream side is arranged to be smaller than the diameter φD of the appropriate medal. Yes.

このような構成により、メダルの検知状態を表す図16のタイムチャートに示すように、両検知センサS11,S12の出力時間、位相差(検知時間T1〜T4及び、その加減算により求められる時間)を検出し、メダルの進行方向を検出すると共に、真偽判定、通過メダルの計数を実施する方法が一般の遊技機において用いられている。   With such a configuration, as shown in the time chart of FIG. 16 showing the detection state of medals, the output times and phase differences (detection times T1 to T4 and times obtained by addition and subtraction) of both detection sensors S11 and S12 are calculated. A general game machine uses a method of detecting and detecting the direction of movement of medals, and determining authenticity and counting passing medals.

従って、スタートスイッチの制御が前記のような遊技機では、メダルの枚数を計数せずに筐体内に取込んでしまう「飲込み」を防止するためには検知センサS11の直前に位置するメダルを排除する必要がある。このため、規制レバーの構成は、該規制レバーの突出までのタイムラグや、メダルの流下速度等を鑑みて、突出位置等を構成している。   Therefore, in a gaming machine in which the start switch is controlled as described above, in order to prevent “swallowing” that is taken into the housing without counting the number of medals, a medal located immediately before the detection sensor S11 is used. Need to be eliminated. For this reason, the configuration of the regulating lever constitutes a protruding position or the like in consideration of a time lag until the protruding of the regulating lever, a flow rate of medals, and the like.

しかし、メダルの投入と、スタートスイッチの押下とのタイミングは、遊技者によって任意に操作可能である。従って、規制レバーがメダル通路に突出した時に、そのメダルの位置、連続して流下するメダルの間隔、メダルの流下速度等は様々となる。   However, the timing at which the medal is inserted and the start switch is pressed can be arbitrarily operated by the player. Therefore, when the control lever protrudes into the medal passage, the position of the medal, the interval between medals that continuously flow down, the flow down speed of medals, and the like vary.

そのため、「飲込み」のみを考慮して規制レバーを構成すると、メダルの突出が早過ぎることによる「誤排除」や「詰り」を増加させてしまう。つまり、図17(A)及び図17(B)に示すように、規制レバー171を突出させるタイミングが、排除すべきメダルM1に対して遅い場合は、メダルが誤通過する「飲込み」が生じ、さらに規制レバー171がメダルM1に接触することにより、メダルM1が規制レバー171に押され、押板のメダルガイド部分172に挟まれて、図17(C)に示すように、「メダル詰り」を発生させることになる。   For this reason, if the restriction lever is configured in consideration of only “swallowing”, the “false exclusion” and “clogging” due to the excessive protrusion of the medal are increased. That is, as shown in FIGS. 17A and 17B, when the timing of projecting the regulating lever 171 is slower than the medal M1 to be excluded, “swallowing” in which the medal passes incorrectly occurs. Further, when the regulating lever 171 contacts the medal M1, the medal M1 is pushed by the regulating lever 171 and is sandwiched between the medal guide portions 172 of the push plate, and as shown in FIG. Will be generated.

さらに、制御部の指令に対し、実際に規制レバーが突出するまでには、機械的なタイムラグがあるため、より「飲込み」が発生しやすくなる。反対に、図18(A)に示すように、規制レバー171の突出が、通過すべきメダルM2に対して、早過ぎる場合では、図18(B)に示すように、通過すべきメダルM2に規制レバー171が接触し、通過すべきメダルM2を排除する「誤排除」や、図18(C)に示すように、規制レバー171の先端部と押板のメダルガイド部分172との間でメダル181がロックされる「メダル詰り」を発生させてしまう。   Furthermore, since there is a mechanical time lag before the control lever actually protrudes in response to a command from the control unit, “swallowing” is more likely to occur. On the other hand, as shown in FIG. 18A, when the protrusion of the regulating lever 171 is too early for the medal M2 to pass, the medal M2 to pass is shown in FIG. 18B. The “wrong exclusion” in which the restriction lever 171 contacts and eliminates the medal M2 to be passed, or as shown in FIG. 18C, the medal between the tip of the restriction lever 171 and the medal guide portion 172 of the push plate. The “medal clogging” in which 181 is locked is generated.

また、「飲込み」が発生した場合は、本来、返却すべきメダルが計数されずに筐体内に取込まれてしまうため、遊技者に不利益を及ぼし、「誤排除」が発生した場合には、再度、投入口にメダルを投入しなければならないため、遊技者の手間が掛かると共に遊技者の趣向も低下する。また、「メダル詰り」が発生した場合には、遊技機がエラーを報知するため、係員の手間が掛かる。   Also, if “swallowing” occurs, the medals that should be returned will be taken into the housing without being counted, which will be disadvantageous to the player and if “false exclusion” occurs. Since it is necessary to insert a medal into the slot again, it takes time and effort for the player, and the player's preference also decreases. In addition, when a “medal clogging” occurs, the gaming machine notifies an error, which takes time for an attendant.

ここで、前記「飲込み」の例をあげると、ゲーム開始に必要な規定枚数のメダル、例えば3枚のメダルを投入し、図19(A)に示すように、さらに連続して、もう1枚余分な4枚目のメダルM4を投入して素早くスタートスイッチを押下した場合に飲込みを発生させやすくなる。   Here, as an example of the “swallowing”, a predetermined number of medals necessary for the start of the game, for example, three medals are inserted, and as shown in FIG. If an extra fourth medal M4 is inserted and the start switch is pressed quickly, swallowing is likely to occur.

この場合は、3枚目のメダルM3を計数した時点で、スタートスイッチの操作が有効になるため、検知センサS11,S12を通過するよりも素早くスタートスイッチが押下されると、そのタイミングやメダルの流下速度等によっては、排除すべき4枚目のメダルM4に対し、「飲込み」や「メダル詰り」が発生してしまう。   In this case, since the operation of the start switch becomes effective when the third medal M3 is counted, if the start switch is pressed more quickly than passing through the detection sensors S11 and S12, the timing and medal Depending on the flow speed and the like, “swallowing” and “medal clogging” occur for the fourth medal M4 to be eliminated.

次に、前記「誤排除」の例をあげると、遊技機のクレジット数が、その最大貯留枚数(例えば50枚)より、1枚少ない状態(クレジット49枚)で、図19(B)に示すように、49枚目のメダルM49に続き、さらに50枚目のメダルM50、51枚目のメダルM51と過剰にメダルが投入された場合に誤排除を発生させやすくなる。   Next, as an example of the “false exclusion”, FIG. 19B shows that the number of credits of the gaming machine is one less (49 credits) than the maximum storage number (for example, 50). As described above, when the medal M49 is excessively inserted after the 49th medal M49 and the 50th medal M50 and the 51st medal M51, it is easy to cause erroneous exclusion.

この場合は、検知センサS11,S12が50枚目のメダルM50を検知した時(例えば、機械的なタイムラグ等を考慮して、上流側の検知センサS11の立下りをトリガに設定)に、通路を切り替え、規制レバー171を突出させる。そのため、メダルの流下速度や投入されたメダルの間隔等によっては、最後に通過させる50枚目のメダルM50に対し、「誤排除」や「メダル詰り」が発生してしまう。   In this case, when the detection sensors S11 and S12 detect the 50th medal M50 (for example, the fall of the upstream detection sensor S11 is set as a trigger in consideration of a mechanical time lag or the like), the path And the regulating lever 171 is protruded. For this reason, depending on the flow rate of medals, the interval between inserted medals, and the like, “false removal” and “medal clogging” occur for the 50th medal M50 to be finally passed.

このような問題の解決手段として、従来から特許文献2に開示されているように、遊技機の制御部において、スタートスイッチの操作を遅延させることで問題を解決する対策案が知られている。   As a means for solving such a problem, as disclosed in Patent Document 2, conventionally, there has been known a countermeasure for solving the problem by delaying the operation of the start switch in the control unit of the gaming machine.

しかしながら、このような対策案では遊技者の操作に違和感を与え、遊技者の趣向を低下させてしまう問題がある。   However, such a countermeasure has a problem that the player's operation is uncomfortable and the player's preference is lowered.

特開2002−172203号JP 2002-172203 A 特許第3224150号Patent No. 3224150

そこで、この発明は前記問題点を解決するため、メダルの速度やスタートスイッチを入力したときの操作等の切替えタイミングの影響を受けず、いかなる状態でメダル通路をメダル取込み側とメダル排除側に切り替えても、通過すべきメダルを通過させ、排除すべきメダルを確実に排除させる投入メダル選別装置及び遊技機を提供することを目的とする。   Therefore, in order to solve the above problems, the present invention switches the medal path between the medal intake side and the medal exclusion side in any state without being influenced by the switching timing of the operation when the medal speed or start switch is input. However, it is an object of the present invention to provide a throw-in medal selection device and a gaming machine that allow a medal to pass through and surely exclude a medal to be eliminated.

この発明は、立姿で対向する基板と開閉板との対向面間に、メダルを自重により縦方向から横方向へと転動させて通過させるL形状のメダル通路と、前記メダル通路の途中には、該メダル通路と対向する部位の開閉板側に開口してメダル類を排除させる排除口と、前記排除口と対向する前記メダル通路の位置には、前記基板の外壁面側より延出させて、該メダル通路のメダル取込み位置とメダル排除位置とに可動変位させ、ここに導かれたメダルをメダル取込み位置側とメダル排除位置側とに振分ける可動ガイド板と、前記可動ガイド板をメダル排除位置側に付勢させる付勢手段と、前記付勢手段の付勢力に抗して前記可動ガイド板をメダル取込み位置側に可動変位させる駆動手段と、前記駆動手段の駆動に連動して基板の外壁面側より前記排除口と対向するメダル通路の部位から没入させる排除ガイド部材と、前記メダル通路を通過するメダルの通過を検知する検知手段とを設けた投入メダル選別装置であって、前記メダル通路を挟んで対向する一方に配設された前記排除ガイド部材と他方に配設されたメダルガイド部との間を流下するメダルに、前記排除ガイド部材が接触することに基づいて該メダルの流下抵抗が高まったとき、前記可動ガイド板のガイド動作を保持したまま、前記排除ガイド部材を前記メダル通路に突出した位置から一時的に退避させる一時退避手段を備えたことを特徴とする。   According to the present invention, an L-shaped medal passage that allows a medal to roll from the vertical direction to the horizontal direction by its own weight between the opposing surfaces of the substrate and the opening and closing plate that are opposed to each other in a standing position, And an exclusion port that opens to the opening / closing plate side of the portion facing the medal passage and excludes medals, and the medal passage facing the exclusion port is extended from the outer wall surface side of the substrate. The movable guide plate is movably displaced between the medal intake position and the medal removal position of the medal passage, and the medal guided here is divided into the medal intake position side and the medal removal position side, and the movable guide plate is excluded from the medal. An urging means for urging the position side, a driving means for movably displacing the movable guide plate to the medal taking-in position side against the urging force of the urging means, and a substrate in conjunction with the driving of the driving means. From the outer wall side An inserted medal sorting device provided with an exclusion guide member for immersing from a medal passage portion facing the mouth opening and a detecting means for detecting passage of medals passing through the medal passage, facing each other across the medal passage When the flow resistance of the medal is increased based on the contact of the exclusion guide member with the medal flowing between the exclusion guide member disposed on one side and the medal guide portion disposed on the other side. And a temporary retracting means for temporarily retracting the exclusion guide member from a position protruding into the medal path while maintaining the guide operation of the movable guide plate.

この発明によると、排除ガイド部材を動作させることによってメダル通路に導かれたメダルを、取込み側と排除側とに1枚ずつ選別することができる。このうち、排除ガイド部材の排除タイミングのずれによって該排除ガイド部材が通過すべきメダルに接触しても、該排除ガイド部材を一時退避させる一時退避手段によってメダルを通過させることができるため、メダルの通過は妨げられなくなり、メダルの詰りを未然に回避することができる。   According to the present invention, the medals guided to the medal path by operating the exclusion guide member can be sorted one by one on the take-in side and on the exclude side. Among these, even if the exclusion guide member comes into contact with the medal to be passed due to the displacement of the exclusion guide member, the medal can be passed by the temporary retracting means for temporarily retracting the exclusion guide member. The passage is not hindered, and the clogging of medals can be avoided in advance.

例えば、投入されたメダルを順に受付けて設定された最大クレジット枚数(最大貯留枚数)になるまで計数しながら取込んでいるとき、その計数値が最大クレジット枚数に達して、受付完了する最終メダル(最大貯留枚数目)を通過させるときに、該最終メダルに対して排除ガイド部材の排除タイミングが早過ぎて、該排除ガイド部材がその最終メダルに誤接触(当接)した場合でも、該排除ガイド部材を通路面より没する方向に逃がすことで、メダルの詰りや誤排除を防止することができる。従って、メダルの飲込みを防止するバネ圧の高い応答性を有するメダルの排除ガイド機能を構成しても、メダルと接触する排除ガイド部材を一時的に退避動作させることによって、メダルの詰りや誤排除を確実に防止できる。   For example, when the inserted medals are sequentially received and taken in until the maximum number of credits set (maximum stored number) is taken in, the final medal that has been accepted (the count value reaches the maximum number of credits) Even when the exclusion guide member is removed too early with respect to the final medal when passing the maximum stored number), the exclusion guide is in contact (contact) with the final medal. By letting the member escape in the direction of sinking from the passage surface, it is possible to prevent clogging of medals and erroneous exclusion. Therefore, even if a medal exclusion guide function having a high spring pressure response to prevent the medal from being swallowed is configured, the medal clogging or error may be caused by temporarily retracting the exclusion guide member in contact with the medal. Exclusion can be reliably prevented.

この発明の別の構成の一時退避手段では、先端に前記排除ガイド部材を有し、基端に前記可動ガイド板に回動自由に枢着される枢着部と該枢着部での回動を規制して前記排除ガイド部材の突出量を制限する突出量制限部とを有する排除ガイドレバーと、前記排除ガイドレバーの枢着部を回動支点に該排除ガイドレバーの排除ガイド部材を、前記メダル通路より退避許容させて前記排除口側に付勢支持する付勢バネとを備えて構成することができる。   According to another aspect of the present invention, the temporary retracting means has the exclusion guide member at the distal end, and a pivoting portion pivotally mounted on the movable guide plate at the proximal end, and pivoting at the pivoting portion. The exclusion guide lever having a projection amount limiting portion that restricts the projection amount of the exclusion guide member by restricting the projection guide member, and the exclusion guide member of the exclusion guide lever using the pivoting portion of the exclusion guide lever as a pivot point, An urging spring that is allowed to retract from the medal passage and is urged and supported on the exclusion port side can be provided.

この発明によると、排除ガイドレバーの基端に有する枢着部を回動支点に該排除ガイドレバーの先端に有する排除ガイド部材を、付勢バネによってメダル通路より退避許容させて前記排除口側に付勢支持している。このため、メダル通路を通過すべきメダルが降下してきたときに、該メダルに排除ガイド部材の排除タイミングがずれて誤接触してしまった場合、メダル通路内で該メダルの流下抵抗が高まり、メダル詰りが生じようとしても、そのときは一時退避手段によって該排除ガイド部材が一時的に退避するため、メダルはメダル通路内で押圧されずに済み、メダル詰りが未然に解消される。   According to the present invention, the exclusion guide member having the pivotally mounted portion at the base end of the exclusion guide lever as a rotation fulcrum is retracted from the medal passage by the urging spring and moved toward the exclusion port. Supports energization. For this reason, when a medal that should pass through the medal passage is lowered, if the removal timing of the exclusion guide member is shifted to the medal and miscontacts, the flow resistance of the medal increases in the medal passage, and the medal Even if clogging is about to occur, the exclusion guide member is temporarily retracted by the temporary retracting means at that time, so that the medal is not pressed in the medal passage, and the medal clogging is eliminated.

この場合、付勢バネの付勢力は排除ガイド部材の先端が立姿で転動してきたメダルの一端面に接触してしまったときに、該メダルの通過を妨げない微弱の付勢圧に設定している。つまり、排除ガイド部材がメダル通路より容易に退避して、メダルの通過を優先させる付勢圧に設定する。一方、メダル通路より排除させるべきメダルが降下してきたときは排除ガイド部材をメダル通路に突出させて、ここに転動してきたメダルの外周縁部が排除ガイド部材に接触して通過規制され、メダルは排除口側に排除される。又、可動ガイド板を付勢支持する付勢手段の付勢圧を弱く設定してしまうと、可動ガイド板の動きが遅くなり、可動ガイド板の応答性が低下して安定した排除性能が得られなくなるので正規の付勢圧を維持させる。   In this case, the urging force of the urging spring is set to a weak urging pressure that does not obstruct the passage of the medal when the tip of the exclusion guide member comes into contact with one end surface of the medal that has rolled in the standing position. ing. That is, the evacuation guide member is easily retracted from the medal passage, and is set to an urging pressure that gives priority to the medal passage. On the other hand, when the medals to be excluded from the medal passage are lowered, the exclusion guide member is protruded into the medal passage, and the outer peripheral edge of the medal that has rolled here comes into contact with the exclusion guide member so that the passage is restricted. Is excluded at the exit side. Also, if the biasing pressure of the biasing means that biases and supports the movable guide plate is set weak, the movement of the movable guide plate slows down, and the response of the movable guide plate is lowered, resulting in stable exclusion performance. Since it cannot be used, the normal bias pressure is maintained.

この発明の別の構成の一時退避手段では、先端に前記排除ガイド部材を有し、基端に前記駆動手段との連結部材に回動自由に枢着される枢着部と該枢着部での回動を規制して前記排除ガイド部材の突出量を制限する突出量制限部とを有する排除ガイドレバーと、前記排除ガイドレバーの枢着部を回動支点に該排除ガイドレバーの排除ガイド部材を、前記メダル通路より退避許容させて前記排除口側に付勢支持する付勢バネとから構成することができる。   According to another aspect of the present invention, the temporary retracting means has the exclusion guide member at the distal end, and a pivoting portion pivotally mounted on the connecting member to the driving means at the proximal end, and the pivoting portion. An exclusion guide lever having a protrusion amount limiting portion for restricting the protrusion amount of the exclusion guide member by restricting the rotation of the exclusion guide member, and an exclusion guide member of the exclusion guide lever with the pivoting portion of the exclusion guide lever as a pivotal fulcrum Can be constituted by an urging spring that is allowed to retract from the medal passage and urged to the evacuation port side.

この発明によると、排除ガイドレバーの基端に形成される枢着部を、駆動手段の連結部材に連結しても一時退避手段を構成することができる。この場合は、可動ガイド板に枢着部を設けるのではなく、駆動手段の連結部材に設けるものであり、このように構成しても排除ガイド部材を付勢バネによってメダル通路より退避許容させることができるため、同様にメダル通路内でのメダル詰りを解消させることができる。   According to the present invention, the temporary retracting means can be configured even if the pivoting portion formed at the base end of the exclusion guide lever is connected to the connecting member of the driving means. In this case, the movable guide plate is not provided with the pivotally attached portion but is provided on the connecting member of the driving means, and even if configured in this way, the exclusion guide member is allowed to retract from the medal passage by the biasing spring. Therefore, the clogging of medals in the medal passage can be eliminated.

この発明の別の構成では、排除ガイド部材の先端部を半球面状に設けることができる。この場合は、排除ガイド部材の先端部がメダルの端面に接触したときに点接触対応してメダルに滑らかに接触対応し、メダルへの引っ掛かりのおそれもなく排除ガイド部材の滑らかな動きを促進できる。   In another structure of this invention, the front-end | tip part of an exclusion guide member can be provided in hemispherical shape. In this case, when the tip of the exclusion guide member comes into contact with the end face of the medal, the medal can be smoothly contacted with the medal and the smooth movement of the exclusion guide member can be promoted without fear of being caught on the medal. .

このように構成された投入メダル選別装置を備えた遊技機を用いれば、排除ガイド部材の選別作用によって、メダル取込み時のメダルの飲込みを防止でき、又、一時退避手段によって、メダル排除時の詰りや誤排除を解消できる信頼性の高い遊技機として運用することができる。   By using the gaming machine equipped with the inserted medal sorting device configured as described above, the sorting action of the exclusion guide member can prevent the swallowing of medals at the time of taking in medals. It can be operated as a highly reliable gaming machine that can eliminate clogging and error exclusion.

この発明によると、遊技機に投入されたメダルを取込み、又は排除してメダルを選別する場合に、いかなる状態でメダル通路をメダル取込み側とメダル排除側に切り替えても、通過すべきメダルを通過させ、排除すべきメダルを確実に排除させて、メダルの飲込み、詰り及び誤排除を防止する信頼性の高いメダルの選別処理ができる。   According to the present invention, when a medal inserted into a gaming machine is taken in or removed and a medal is selected, the medal to be passed is passed regardless of the state where the medal passage is switched between the medal taking side and the medal removing side. Therefore, the medal to be eliminated can be surely eliminated, and the medal sorting process with high reliability can be performed to prevent the swallowing, clogging and erroneous exclusion of the medal.

この発明の一実施例を以下図面に基づいて説明する。
図面は遊技機の一例として遊技ホールに設置されるスロットマシンを示し、図1において、このスロットマシン11は接客面としての前面上部にパネル12とリール部13を有し、前面中央の幅方向に3個の並列するストップボタン14を有し、その左側にスタートレバー15と掛け数設定ボタン16を有し、右側に清算ボタン17とメダルMを1枚ずつ投入するための投入口18を有し、これらの前面下部に下皿19を有している。
An embodiment of the present invention will be described below with reference to the drawings.
The drawing shows a slot machine installed in a game hall as an example of a gaming machine. In FIG. 1, this slot machine 11 has a panel 12 and a reel part 13 at the front upper part as a customer service surface, and in the width direction of the front center. It has three stop buttons 14 arranged in parallel, a start lever 15 and a multiplier setting button 16 on the left side, and a clearing button 17 and a slot 18 for inserting medals M one by one on the right side. The lower plate 19 is provided at the lower part of the front surface.

そして、遊技者がスロットマシン11を遊技利用するときに、前記投入口18にメダルMが1枚ずつ投入される。投入されたメダルMは内部で選別され、有効と選別された正規のメダルMは内部に取込まれ、無効と選別された不適合の大きさのメダル類はメダル返却通路(図2参照)26を介して下皿19へと返却させる選別機能を有している。又、遊技者が遊技を中止するために清算ボタン17を押下操作した場合もメダルMは下皿19へと返却される。   Then, when the player uses the slot machine 11 for games, medals M are inserted into the insertion slot 18 one by one. The inserted medals M are selected inside, the regular medals M selected as valid are taken into the inside, and medals of a nonconforming size selected as invalid are passed through the medal return passage 26 (see FIG. 2). And a sorting function for returning to the lower plate 19. The medal M is also returned to the lower plate 19 when the player depresses the clearing button 17 to stop the game.

図2はスロットマシン11の前面扉11aを片開き式に開口した扉の内部構造を示し、この開口されたスロットマシン本体11b側には、リール部13の外周面の絵柄の位置を回転・停止させて遊技利用を行う。例えば、3列のリール部13を上部に設置し、下部中央にメダルの取込み及び払い出し用のメダル払出装置21を設置し、その左側に電源装置22を設置し、右側にオーバフロータンク23を設置している。   FIG. 2 shows the internal structure of the door in which the front door 11a of the slot machine 11 is opened in a single-opening manner. The position of the pattern on the outer peripheral surface of the reel unit 13 is rotated and stopped on the side of the opened slot machine main body 11b. Let the game use. For example, three rows of reel portions 13 are installed at the top, a medal payout device 21 for taking in and out medals is installed at the bottom center, a power supply device 22 is installed on the left side, and an overflow tank 23 is installed on the right side. ing.

一方、前面扉11a側には、内面上部より下部にかけてリールカバー24と、メダルの適否を選別する投入メダル選別装置(メダルセレクタ)25と、メダル返却通路26と、返却口27とをこの順に有している。   On the other hand, on the front door 11a side, there are a reel cover 24, an inserted medal sorting device (medal selector) 25 for selecting the suitability of medals, a medal return passage 26, and a return port 27 in this order from the upper part to the lower part of the inner surface. is doing.

上述のメダルセレクタ25は、図3及び図4に示すように、平面視コの字状の基板28と、開閉板29とを備え、開閉板29側の支軸30を基板28側の軸受部31に軸支すると共に、バネ32により開閉板29を常時基板28側に付勢し、これら基板28と開閉板29との両者によりメダル通路33を形成している。   3 and 4, the medal selector 25 includes a U-shaped substrate 28 in plan view and an opening / closing plate 29, and the support shaft 30 on the opening / closing plate 29 side serves as a bearing portion on the substrate 28 side. The opening / closing plate 29 is always urged toward the substrate 28 by the spring 32 while being pivotally supported by the spring 31, and the medal passage 33 is formed by both the substrate 28 and the opening / closing plate 29.

このメダル通路33は前述の投入口18に接続対応する入口34と下方の出口35とを有するL字状に形成され、入口34から下方に延びる縦辺部L1と、斜め下方に延びて出口35に至る横辺部L2と、これら両辺部L1,L2を湾曲状に連通接続する湾曲部L3とを備えている。   The medal passage 33 is formed in an L shape having an inlet 34 corresponding to the insertion port 18 and a lower outlet 35, and has a vertical side L1 extending downward from the inlet 34 and an outlet 35 extending obliquely downward. And a curved portion L3 that connects the side portions L1 and L2 in a curved shape.

又、図5に示すように基板28の裏側に有する支軸36を支点として揺動可能な可動ガイド板37を設け、この可動ガイド板37のガイド部38を基板28の開口部39から図3、図4に示すようにメダル通路33の上部に隣設し、このガイド部38でメダルMの上端側を搬送方向にガイドするように構成している。   Further, as shown in FIG. 5, there is provided a movable guide plate 37 that can be swung with a support shaft 36 provided on the back side of the substrate 28 as a fulcrum. As shown in FIG. 4, it is arranged adjacent to the upper part of the medal passage 33, and the guide portion 38 is configured to guide the upper end side of the medal M in the transport direction.

さらに、上述の可動ガイド板37には図5に示すように基板28の裏側に位置する排除部材としての排除ガイドレバー40を下方に垂設しており、この排除ガイドレバー40の下端に設けた後述するブロッカ部50を、メダル通路33の下流側に開口した開口部33aから該メダル通路33に向けて出没可能に構成している。   Further, as shown in FIG. 5, an exclusion guide lever 40 as an exclusion member located on the back side of the substrate 28 is suspended downward from the movable guide plate 37 and provided at the lower end of the exclusion guide lever 40. A blocker portion 50 to be described later is configured to be able to appear and retract toward the medal passage 33 from an opening portion 33a opened on the downstream side of the medal passage 33.

又、上述の基板28の裏側にはソレノイド41と、該ソレノイド41により駆動される可動板42を設け、この可動板42の遊端42aを可動ガイド板37の上端37aに対向させている。そして、ソレノイド41の非励磁時(OFF)には後述するバネ(図6参照)52により可動ガイド板37を、メダル排除方向に付勢して、可動ガイド板37のガイド部38はメダルMの上端側の搬送ガイドを解除すると共に、排除ガイドレバー40の下端のブロッカ部50をメダル通路33の開口部33aからメダル通路33側へ突出させて、受入れを中止させている。   A solenoid 41 and a movable plate 42 driven by the solenoid 41 are provided on the back side of the substrate 28 described above, and the free end 42 a of the movable plate 42 is opposed to the upper end 37 a of the movable guide plate 37. When the solenoid 41 is not energized (OFF), the movable guide plate 37 is biased in the medal removal direction by a spring (see FIG. 6) 52 described later, so that the guide portion 38 of the movable guide plate 37 has the medal M. The transfer guide on the upper end side is released, and the blocker portion 50 at the lower end of the exclusion guide lever 40 is protruded from the opening 33a of the medal passage 33 toward the medal passage 33 to stop the acceptance.

ソレノイド41の励磁時(ON)には、可動板42の遊端42aで可動ガイド板37の上端37aを吸引し、可動ガイド板37をバネ52の付勢力に抗して、可動ガイド板37のガイド部38でメダルMの上端側を搬送ガイドすると共に、排除ガイドレバー40の下端のブロッカ部50をメダル通路33の開口部33aから裏面側に後退させ、有効と選別された正規のメダルはメダル払出装置21へ搬送し、無効と選別された不適合の大きさのメダル類は開閉板29の排除口29aから排除して、外部の返却口27に返却するように構成している。   When the solenoid 41 is energized (ON), the free end 42 a of the movable plate 42 attracts the upper end 37 a of the movable guide plate 37, and the movable guide plate 37 is resisted against the biasing force of the spring 52. The guide part 38 conveys and guides the upper end side of the medal M, and the blocker part 50 at the lower end of the exclusion guide lever 40 is moved backward from the opening part 33a of the medal passage 33 so that a valid medal selected as valid is a medal. The non-conforming medals that are transported to the payout device 21 and selected as invalid are excluded from the exclusion port 29a of the opening / closing plate 29 and returned to the external return port 27.

前記メダル通路33の横辺部L2は、該横辺部L2の上下に対設される可動ガイド板37と通路の下面を形成する案内プレート33bとの上下に平行する平行間隔により直径の小さなメダルを通路外に排除する外形選別を実施し、正規の大きさのメダルのみを通過させて計数するように構成している。   The lateral side L2 of the medal passage 33 is a medal having a small diameter due to the parallel spacing between the movable guide plate 37 provided above and below the lateral side L2 and the guide plate 33b that forms the lower surface of the passage. Is selected so that only medals of a normal size are allowed to pass through and counted.

従って、出口35からは遊技機専用に設けられた一定の大きさの円板形状を有する適正な大きさのメダルMのみが受入れられる。この出口35の直前部においてメダル通路33を形成する基板28の通路壁には、メダル通路33の横辺部L2を通過するメダルMを検知して計数する第1センサS1と第2センサS2とを、この通路方向に順に取付けている。   Accordingly, from the exit 35, only medals M of a proper size having a disc shape of a certain size provided exclusively for gaming machines are accepted. A first sensor S1 and a second sensor S2 that detect and count the medal M passing through the lateral side portion L2 of the medal passage 33 are formed on the passage wall of the substrate 28 forming the medal passage 33 immediately before the outlet 35. Are sequentially attached in the direction of this passage.

これらのセンサS1,S2は投受光してメダルMの通過を検知する光学式検知センサで構成することができ、メダルMがメダル通路33に沿って下流側に移動し、このメダルMが両センサS1,S2の光軸をこの順に遮ることで、メダルMの通過を検出する。具体的には、メダルの進行方向を検出すると共に、センサ出力時間、位相差、出力順位などを検出し、メダルの真偽判定・通過メダル枚数の計数を実施するため、適正なメダルの直径より小さくなる間隔に2つのセンサS1,S2を配置している。図3において、Kはセンサ保護カバーを示す。   These sensors S1 and S2 can be constituted by optical detection sensors that project and receive light and detect the passage of the medal M, and the medal M moves downstream along the medal path 33. By blocking the optical axes of S1 and S2 in this order, the passage of the medal M is detected. Specifically, in addition to detecting the direction of movement of medals, the sensor output time, phase difference, output order, etc. are detected, and the authenticity of medals is determined and the number of passing medals is counted. Two sensors S1 and S2 are arranged at a smaller interval. In FIG. 3, K indicates a sensor protective cover.

ところで、排除ガイドレバー40にはメダル通路33に突出させた位置から一時的に退避させる一時退避機構43を備えている。この一時退避機構43は、図6に示すように、排除ガイドレバー40を構成する上レバー部44と、その下部の下レバー部45とに分割することで、下レバー部45を一時退避可能に構成するものである。   By the way, the exclusion guide lever 40 is provided with a temporary retraction mechanism 43 that temporarily retreats from the position projected in the medal passage 33. As shown in FIG. 6, the temporary retracting mechanism 43 is divided into an upper lever portion 44 that constitutes the exclusion guide lever 40 and a lower lever portion 45 below the upper lever portion 44, so that the lower lever portion 45 can be temporarily retracted. It constitutes.

前記上レバー部44は可動ガイド板37より一体に折り曲げて垂設し、該上レバー部44が可動ガイド板37の支軸36を回動支点に回動する。このため、可動ガイド板37と一体化して回動し、この上レバー部44の下端に下レバー部45を同回動方向に枢着している。この枢着部は両レバー部44,45を枢支軸46によって枢支し、この枢支軸46上に巻回したコイル状のバネ47によって、下レバー部45の下端をメダル通路33側に突出させる方向に付勢している。   The upper lever portion 44 is bent from the movable guide plate 37 so as to be vertically suspended, and the upper lever portion 44 rotates about the support shaft 36 of the movable guide plate 37 as a rotation fulcrum. For this reason, it rotates integrally with the movable guide plate 37, and the lower lever part 45 is pivotally attached to the lower end of the upper lever part 44 in the same rotational direction. The pivoting portion pivots both lever portions 44 and 45 with a pivot shaft 46, and the lower end of the lower lever portion 45 is moved toward the medal passage 33 by a coiled spring 47 wound around the pivot shaft 46. It is energized in the protruding direction.

該下レバー部45は上部に突出量制限片48を設け、該突出量制限片48が上レバー部44の反付勢方向に対応する係合凹部49に係合して、該下レバー部45の下端に設けられるメダルをブロックして排除するためのブロッカ部50の突出量を制限している。   The lower lever portion 45 is provided with a protruding amount limiting piece 48 at the upper portion, and the protruding amount limiting piece 48 engages with an engaging recess 49 corresponding to the counter-biasing direction of the upper lever portion 44, and the lower lever portion 45. The amount of protrusion of the blocker portion 50 for blocking and removing medals provided at the lower end of the block is limited.

前記ブロッカ部50は下レバー部45の下端に、メダル通路33と直交する向きに形成され、このブロッカ部50をメダル通路33に対して出没させるものである。   The blocker portion 50 is formed at the lower end of the lower lever portion 45 in a direction orthogonal to the medal passage 33, and the blocker portion 50 is projected and retracted with respect to the medal passage 33.

このブロッカ部50の先端部は半球面状に設け、この半球面状に設けることにより、ブロッカ部50がメダルMの端面に接触したときに点接触対応してメダルMとの間で接触抵抗が小さくなり、ブロッカ部50及びメダルMとの相互が滑らかな動きになる。   The tip of the blocker part 50 is provided in a hemispherical shape, so that when the blocker part 50 comes into contact with the end face of the medal M, contact resistance between the blocker part 50 and the medal M is achieved. It becomes small and a mutual movement with the blocker part 50 and the medal M becomes smooth.

前記可動ガイド板37は、基板28のメダル通路33の裏面に設けられた軸受51に支軸36で懸架され、軸受51を中心に回動可能に軸支されている。さらに、支軸36上に巻回されたコイル状のバネ52により、該可動ガイド板37を常時メダル通路33より退避する方向に付勢している。又、このバネ52の付勢力により排除ガイドレバー40を構成する上レバー部44と下レバー部45とを常時メダル通路33より退避する方向に付勢している。このため、ソレノイド41が非励磁時ではバネ52によって下レバー部45と一体のブロッカ部50はメダル通路33に突出してメダルMの通過を阻止している。   The movable guide plate 37 is suspended by a support shaft 36 on a bearing 51 provided on the back surface of the medal passage 33 of the substrate 28, and is rotatably supported around the bearing 51. Further, the movable guide plate 37 is constantly urged in the direction of retreating from the medal passage 33 by a coiled spring 52 wound on the support shaft 36. The urging force of the spring 52 urges the upper lever portion 44 and the lower lever portion 45 constituting the exclusion guide lever 40 in a direction in which they are always retracted from the medal passage 33. For this reason, when the solenoid 41 is not energized, the blocker portion 50 integrated with the lower lever portion 45 protrudes into the medal passage 33 by the spring 52 and prevents the medal M from passing therethrough.

さらに、バネ52の荷重はブロッカ部50の突出までの機械的なタイムラグを小さくするため、ソレノイド41が吸引可能な範囲で極力高く設定する。
つまり、可動ガイド板37を付勢支持するバネ52の付勢圧を弱く設定してしまうと、可動ガイド板37の動きが遅くなり、可動ガイド板37の応答性が低下して安定した排除性能が得られなくなるので高い付勢圧に設定する。
Furthermore, the load of the spring 52 is set as high as possible within the range that the solenoid 41 can suck in order to reduce the mechanical time lag until the blocker 50 protrudes.
That is, if the biasing pressure of the spring 52 that biases and supports the movable guide plate 37 is set weak, the movement of the movable guide plate 37 is slowed down, and the responsiveness of the movable guide plate 37 is lowered, thereby eliminating the stable performance. Since it becomes impossible to obtain, a high bias pressure is set.

このように、可動ガイド板37を付勢するバネ52の荷重を高くし、ブロッカ部50を素早く突出させ、且つブロッカ部50の突出位置をメダル通路33の出口35側に構成することで、メダルの飲込みを防止する構成としている。   In this way, by increasing the load of the spring 52 that biases the movable guide plate 37, the blocker part 50 is quickly protruded, and the protruding position of the blocker part 50 is configured on the outlet 35 side of the medal path 33. It is configured to prevent swallowing.

一方、バネ47の荷重は、メダルの流下速度、質量や摩擦抵抗などにより、ブロッカ部50がメダルに接触しても、メダル詰りにならない荷重に設定する。つまり、バネ47の付勢力は、通過すべきメダルMに対し、ブロッカ部50の先端が誤タイミングによって、立姿で転動してきたメダルMの一端面に仮に誤接触してしまったときに、ブロッカ部50がメダル通路33より容易に退避して、メダルMの通過を妨げない微弱の付勢圧にしている。   On the other hand, the load of the spring 47 is set to a load that does not clog the medal even when the blocker unit 50 comes into contact with the medal due to the flow speed, mass, frictional resistance, etc. of the medal. That is, the urging force of the spring 47 is such that when the tip of the blocker 50 is in contact with one end surface of the medal M that has been rolling in a standing position due to an erroneous timing, the blocker 50 The portion 50 is easily retracted from the medal passage 33 to make a weak biasing pressure that does not prevent the medal M from passing.

このように、ブロッカ部50が通過すべきメダルに誤接触した場合には、ブロッカ部50を通路面より没する方向に逃がすことで、詰りや誤排除を防止する構成としている。   In this way, when the blocker unit 50 makes an erroneous contact with a medal to pass, the blocker unit 50 is allowed to escape from the passage surface, thereby preventing clogging and erroneous exclusion.

そして、スロットマシン11がメダルMを受付けるメダル受付状態では、図示しない制御部がソレノイド41への供給電源をONにして励磁状態を保つ。このソレノイド41の励磁状態では、励磁力に基づいて可動する可動板42の可動力を受けた可動ガイド板37がメダル通路33を確保する正規の位置で待機し、ブロッカ部50は可動ガイド板37の動きに連動し、バネ52の付勢力に抗してメダル通路33から没入した状態を維持する。   In the medal acceptance state in which the slot machine 11 accepts the medal M, a control unit (not shown) turns on the power supply to the solenoid 41 to keep the excitation state. In the excited state of the solenoid 41, the movable guide plate 37 that receives the movable force of the movable plate 42 that moves based on the exciting force waits at a proper position that secures the medal passage 33, and the blocker unit 50 moves to the movable guide plate 37. In conjunction with this movement, the state of being immersed from the medal passage 33 against the urging force of the spring 52 is maintained.

これに対し、スロットマシン11がメダルMを受付けないメダル非受付状態では、図示しない制御部がソレノイド41への供給電源をOFFにして非励磁状態にする。このソレノイド41の非励磁状態では、可動ガイド板37はメダル通路33を開放する位置に可動し、ブロッカ部50は可動板42を介した可動ガイド板37の動作により回動されてメダル通路33に突出し、図7に示すように、ここに転動してきたメダルMの外周縁部がブロッカ部50に接触して通過規制され、メダルMは排除口29a側に排除される。   On the other hand, in the medal non-accepting state where the slot machine 11 does not accept the medal M, the control unit (not shown) turns off the power supply to the solenoid 41 and puts it in the non-excited state. In the non-excited state of the solenoid 41, the movable guide plate 37 is moved to a position where the medal passage 33 is opened, and the blocker unit 50 is rotated by the operation of the movable guide plate 37 via the movable plate 42 to enter the medal passage 33. As shown in FIG. 7, the outer peripheral edge of the medal M that rolls here comes into contact with the blocker 50 and is restricted from passing, and the medal M is excluded to the exclusion port 29 a side.

さらに、メダル通路33を通過すべきメダルMが降下してきたときに、該メダルMにブロッカ部50の排除タイミングがずれて該ブロッカ部50が誤接触した場合においても、枢支軸46を回動支点にバネ47によってブロッカ部50をメダル通路33より一時退避させる一時退避機構43が働いて該ブロッカ部50をメダル通路33より一時的に退避させる。   Further, when the medal M that should pass through the medal passage 33 is lowered, the pivot shaft 46 is rotated even when the blocker 50 is erroneously brought into contact with the medal M because the removal timing of the blocker 50 is shifted. A temporary retracting mechanism 43 that temporarily retracts the blocker unit 50 from the medal passage 33 by the spring 47 acts on the fulcrum to temporarily retract the blocker unit 50 from the medal passage 33.

従って、メダル通路33を構成する基板28と、メダル通路33に沿う開閉板29のメダルガイド部29bとのメダル厚さ方向の通路間で、メダルMがブロッカ部50によってメダルガイド部29bに押し付けられて挟持され、メダル通路33内で該メダルMの流下抵抗が高まることに基づいてメダル詰りが生じようとしても、該ブロッカ部50が一時退避してメダル詰りを未然に解消するものである。このため、メダルMはメダル通路33内で押圧されずに済み、メダルMの通過は妨げられなくなり、メダルの通過を許容する。   Accordingly, the medal M is pressed against the medal guide portion 29b by the blocker portion 50 between the passage in the medal thickness direction between the board 28 constituting the medal passage 33 and the medal guide portion 29b of the opening / closing plate 29 along the medal passage 33. Even if the clogging of the medal M is caused in the medal passage 33 due to an increase in the flow resistance of the medal M, the blocker unit 50 is temporarily retracted to eliminate the clogging of the medal. For this reason, the medal M does not need to be pressed in the medal passage 33, the passage of the medal M is not hindered, and the passage of the medal is permitted.

前記ブロッカ部50の回動方向は、メダルMの通過方向に直交させるのが好ましいが、これに限らず、斜め方向など任意の方向から突出させてもよい。又、ブロッカ部50を可動させる動作は、枢支軸46を回動支点とする回転運動に限らず、直線運動にしてもよい。   The rotation direction of the blocker unit 50 is preferably orthogonal to the passing direction of the medal M, but is not limited thereto, and may be protruded from an arbitrary direction such as an oblique direction. In addition, the operation of moving the blocker unit 50 is not limited to the rotational motion with the pivot shaft 46 as the rotational fulcrum, but may be a linear motion.

前記ブロッカ部50の配設位置は、メダルの流下速度やバネ52の荷重(ブロッカ部50の突出までの機械的なタイムラグ)等から上流側の第1センサS1の光軸の直前のメダルMを排除可能な位置に配設する。さらに、開閉板29のセンサ付近のメダルガイド部29bの形状は、出口35側の第2センサS2の光軸がメダルを検知した時に、そのメダルが排除されないように排除口29aを次第に狭めるガイド形状に設ける。   The arrangement position of the blocker unit 50 is determined based on the medal M immediately before the optical axis of the first sensor S1 on the upstream side from the flow speed of the medal and the load of the spring 52 (mechanical time lag until the blocker unit 50 protrudes). It arrange | positions in the position which can be excluded. Furthermore, the shape of the medal guide portion 29b in the vicinity of the sensor of the opening / closing plate 29 is a guide shape that gradually narrows the exclusion port 29a so that the medal is not excluded when the optical axis of the second sensor S2 on the exit 35 side detects the medal. Provided.

又、ブロッカ部50の位置を第1センサS1より上流側となる直前のメダルMを直ちに排除できるように配設したため、スタートレバー15を素早く操作した場合等でもメダルの飲込みやメダル詰りは発生しない。   In addition, since the position of the blocker unit 50 is arranged so that the medal M immediately before the upstream side of the first sensor S1 can be immediately removed, even if the start lever 15 is operated quickly, medals are swallowed or medals are clogged. do not do.

前記メダルガイド部29bは第2センサS2の光軸がメダルMを検知した時のメダルを取込みガイドするため、最大貯留枚数目の通路切り替え時のトリガは、第2センサS2の検知時が望ましい。さらに、ブロッカ部50の突出位置、バネ52の荷重の設定等から高応答性の飲込みに強い構成にすることができる。   Since the medal guide part 29b takes in and guides the medal when the optical axis of the second sensor S2 detects the medal M, the trigger at the time of switching the passage of the maximum stored number is preferably at the time of detection by the second sensor S2. Furthermore, it can be set as the structure strong against swallowing of high responsiveness from the protrusion position of the blocker part 50, the setting of the load of the spring 52, etc.

このように構成された投入メダル選別装置25の処理動作を次に説明する。
今、スロットマシン11の制御部がメダルMの受付けを許可している場合はソレノイド41に電源を供給して励磁状態を維持させる。このとき、可動ガイド板37はソレノイド41の励磁作用を受け、正面側から見たメダル通路33を表す図8をA−A断面して示す図9の厚さ方向のメダル通路33に示すように、バネ52の付勢力に抗して可動ガイド板37を正規のメダル通路33の形成位置に維持させている。
Next, the processing operation of the inserted medal sorting device 25 configured as described above will be described.
If the control unit of the slot machine 11 now accepts the medal M, power is supplied to the solenoid 41 to maintain the excited state. At this time, the movable guide plate 37 is subjected to the exciting action of the solenoid 41, as shown in the medal path 33 in the thickness direction of FIG. The movable guide plate 37 is maintained at the position where the regular medal passage 33 is formed against the urging force of the spring 52.

そして、遊技者により投入口18に投入されたメダルMは、内方の投入メダル選別装置25へと搬送され、この投入メダル選別装置25を流下する立姿のメダルMは、その上下方向に対応する可動ガイド板37と案内プレート33bとの通路間隔の大きさによりメダルの径方向をガイドし、メダルMの外形寸法に応じて適切なメダルか否かを選別し、選別されたメダルMはセンサS1,S2により検知されて通過枚数が計数される。ここで、メダルの受入れ不能な小さいメダルは、コイン返却通路26を流下させて遊技者に返却される。   Then, the medal M inserted into the insertion slot 18 by the player is conveyed to the inner insertion medal sorting device 25, and the standing medal M flowing down the insertion medal sorting device 25 corresponds to the vertical direction. The radial direction of the medal is guided by the size of the passage distance between the movable guide plate 37 and the guide plate 33b, and it is selected whether or not it is an appropriate medal according to the outer dimension of the medal M. The selected medal M is the sensor S1. , S2 and the number of passing sheets is counted. Here, small medals that cannot accept medals flow down the coin return passage 26 and are returned to the player.

一方、スロットマシン11の制御部がメダルMの受付けを拒否している場合は、ソレノイド41に電源を供給せず、非励磁状態にする。このため、可動ガイド板37はソレノイド41の励磁作用を受けず、正面側から見たメダル通路33を表す図10をA−A断面して示す図11の厚さ方向のメダル通路33に示すように、バネ52の付勢力に抗して可動ガイド板37をメダル通路33の排除方向に移動させてメダル通路33を開放した状態にする。又、このとき、排除ガイドレバー40を構成する上レバー部44と下レバー部45も排除方向に回動する。そして、下レバー部45の下端のブロッカ部50がメダル通路33に突出して、ここに導かれたメダルMを確実に排除口29aより排除動作させる。   On the other hand, when the control unit of the slot machine 11 refuses to accept the medal M, the solenoid 41 is not supplied with power and is in a non-excited state. For this reason, the movable guide plate 37 is not subjected to the excitation action of the solenoid 41, and is shown in the medal path 33 in the thickness direction of FIG. In addition, the movable guide plate 37 is moved in the direction of removal of the medal passage 33 against the urging force of the spring 52 so that the medal passage 33 is opened. At this time, the upper lever portion 44 and the lower lever portion 45 constituting the exclusion guide lever 40 also rotate in the exclusion direction. Then, the blocker portion 50 at the lower end of the lower lever portion 45 projects into the medal passage 33, and the medal M guided here is surely removed from the exclusion port 29a.

このように、メダル通路33を開放する向きに可動ガイド板37を回動させることで、メダル通路33をメダル通過方向から排除方向に切替える。又、このとき、メダル通路33にメダルMの通過を防止させるブロッカ部50を突出させることで、筐体内へのメダルMの取込みを防止する。   In this way, by rotating the movable guide plate 37 in the direction to open the medal passage 33, the medal passage 33 is switched from the medal passage direction to the exclusion direction. At this time, the blocker 50 that prevents the medal M from passing through the medal passage 33 protrudes to prevent the medal M from being taken into the housing.

ところで、メダル通路33を通過すべき通路から排除すべき通路に切替えるときに、可動ガイド板37と一体の排除ガイドレバー40を動作させる。ところが、該排除ガイドレバー40の排除タイミングがずれて、該排除ガイドレバー40と一体のブロッカ部50がメダルMに誤接触してしまった場合、メダル通路33内で該メダルMの流下抵抗が高まり、メダル詰りが生じようとすることがある。   By the way, when switching from the passage that should pass through the medal passage 33 to the passage that should be excluded, the exclusion guide lever 40 integrated with the movable guide plate 37 is operated. However, when the exclusion timing of the exclusion guide lever 40 is shifted and the blocker portion 50 integrated with the exclusion guide lever 40 erroneously contacts the medal M, the flow resistance of the medal M increases in the medal passage 33. , Medal clogging may occur.

この場合は、正面側から見たメダル通路33を表す図12をA−A断面して示す図13の厚さ方向のメダル通路33に示すように、枢支軸46を回動支点にバネ47によってブロッカ部50をメダル通路33より一時退避させる一時退避作用が働く。この一時退避作用によって、該ブロッカ部50はメダル通路33より一時的に退避するため、メダルMはメダル通路33内で押圧されずに済み、メダルMの通過は妨げられなくなり、メダル詰りが未然に解消されて取込まれる。   In this case, as shown in the medal path 33 in the thickness direction of FIG. 13 showing the medal path 33 viewed from the front side in FIG. As a result, a temporary retracting action for temporarily retracting the blocker unit 50 from the medal passage 33 is performed. Due to this temporary retracting action, the blocker portion 50 is temporarily retracted from the medal passage 33, so that the medal M is not pressed in the medal passage 33, the passage of the medal M is not hindered, and the medal jam is obstructed. It is canceled and taken in.

例えば、投入されたメダルMを順に受付けて設定されたクレジット枚数(最大貯留枚数目)になるまで計数しながら取込んでいるとき、その計数値が最大貯留枚数に達して、受付完了する最大貯留枚数目のメダルを通過させるときに、該最大貯留枚数目のメダルに対してブロッカ部50の排除タイミングが早過ぎて、該ブロッカ部50がその最大貯留枚数目のメダルに誤接触した場合でも、該ブロッカ部50を通路面より没する方向に逃がすことで、メダルMの詰りや誤排除を防止することができる。   For example, when the inserted medals M are sequentially received and taken in while counting until the set number of credits (the maximum number of stored sheets) is reached, the counted value reaches the maximum stored number and the maximum storage is completed. Even when the blocker 50 is removed too early with respect to the maximum stored number of medals when passing the number of medals, the blocker unit 50 erroneously contacts the maximum stored number of medals. By allowing the blocker part 50 to escape from the passage surface, the medal M can be prevented from being jammed or mistakenly excluded.

図14は一時退避機構の別の実施例を示し、上述の実施例とは一時退避機構のみが異なり、他は同一の構成であるため、この異なる一時退避機構151の部分についてのみ説明する。   FIG. 14 shows another embodiment of the temporary evacuation mechanism. Since only the temporary evacuation mechanism is different from the above-described embodiment and the other configuration is the same, only the portion of the different temporary evacuation mechanism 151 will be described.

この一時退避機構151は基板152の背面側に取付けられたソレノイド153の励磁・非励磁に伴う吸引・開放動作によって可動する可動板154の下端に、上述の実施例の下レバー部45に相当するL形状の排除ガイドレバー155を枢着し、前記可動板154の回動力を該排除ガイドレバー155が直接受けて上述の実施例の可動ガイド板37を経由せずに該排除ガイドレバー155を通路側より一時退避可能に構成したものである。   This temporary retraction mechanism 151 corresponds to the lower lever portion 45 of the above-described embodiment at the lower end of the movable plate 154 that is movable by the suction / release operation associated with the excitation / non-excitation of the solenoid 153 attached to the back side of the substrate 152. An L-shaped exclusion guide lever 155 is pivotally mounted, and the rotational force of the movable plate 154 is directly received by the exclusion guide lever 155 and passes through the exclusion guide lever 155 without passing through the movable guide plate 37 of the above-described embodiment. It can be temporarily saved from the side.

前記可動板154は基板152の背面側上部に突出する支持片156に回動自由に支持され、バネ157によって該可動板154の下部をメダル通路158側より退避する方向に付勢支持している。又、可動板154をソレノイド153によって回動可能に可動板154の中央部をソレノイド153に近接させて対設している。   The movable plate 154 is rotatably supported by a support piece 156 projecting from the back side upper portion of the substrate 152, and a lower portion of the movable plate 154 is urged and supported by a spring 157 in a direction of retreating from the medal path 158 side. . In addition, the movable plate 154 is opposed to the solenoid 153 so that the central portion of the movable plate 154 can be rotated by the solenoid 153.

そして、この可動板154の下端に、該可動板154と同回動方向に設定してL形状の排除ガイドレバー155の垂直片側を枢着する。この枢着部は可動板154と排除ガイドレバー155を枢支軸159によって枢支し、この枢支軸159上に巻回したコイル状のバネ160によって、該排除ガイドレバー155のL形状の水平片側の端部をブロッカ部161として、メダル通路158の開口部158aより突出させる方向に付勢している。   Then, the vertical one side of the L-shaped exclusion guide lever 155 is pivotally attached to the lower end of the movable plate 154 in the same rotational direction as the movable plate 154. The pivoting portion pivotally supports a movable plate 154 and an exclusion guide lever 155 with a pivot shaft 159, and an L-shaped horizontal of the exclusion guide lever 155 is provided by a coiled spring 160 wound around the pivot shaft 159. One side end portion is used as a blocker portion 161 and is biased in a direction of projecting from the opening portion 158a of the medal passage 158.

前記バネ160は一端を可動板154に係止させ、他端を排除ガイドレバー155に係止させてブロッカ部161の突出量を制限しており、通常はブロッカ部161がメダル通路158の開口部158aより突出した位置に待機されている。   One end of the spring 160 is locked to the movable plate 154 and the other end is locked to the exclusion guide lever 155 to limit the amount of protrusion of the blocker portion 161. Normally, the blocker portion 161 is the opening portion of the medal passage 158. It waits in the position which protruded from 158a.

この場合も、バネ160の荷重は、メダルの流下速度、質量や摩擦抵抗などにより、ブロッカ部161がメダルに誤接触しても、メダル詰りにならない荷重に設定する。さらに、ブロッカ部161の先端部についても、上述の実施例と同様に半球面状に設けて、メダルMの端面に接触したときに点接触対応するように構成している。   Also in this case, the load of the spring 160 is set to a load that does not cause clogging even if the blocker portion 161 makes a mistake in contact with the medal due to the flow speed, mass, frictional resistance, etc. of the medal. Further, the tip portion of the blocker portion 161 is also provided in a hemispherical shape in the same manner as in the above-described embodiment, and is configured to correspond to point contact when contacting the end surface of the medal M.

そして、メダル受付状態ではソレノイド153を励磁状態にし、これに基づいてブロッカ部161は、バネ157の付勢力に抗してメダル通路158から没入した状態を維持し、メダルMの通過を許容している。   Then, in the medal acceptance state, the solenoid 153 is energized, and based on this, the blocker portion 161 maintains the state of being immersed from the medal passage 158 against the urging force of the spring 157 and allows the medal M to pass. Yes.

これに対し、メダル非受付状態ではソレノイド153を非励磁状態にし、これに基づいてブロッカ部161は可動板154の動作によりメダル通路158に突出し、ここに転動してきたメダルMの通過を規制して、メダルMを前記実施例と同様の排除口側に排除する。   On the other hand, when the medal is not accepted, the solenoid 153 is de-energized, and based on this, the blocker portion 161 protrudes into the medal path 158 by the operation of the movable plate 154 and restricts the passage of the medal M rolling here. Thus, the medal M is excluded on the same side as the above-described embodiment.

さらに、メダル通路158を通過すべきメダルMが降下してきたときに、ブロッカ部161の排除タイミングがずれて該ブロッカ部161がメダルMに誤接触した場合においても、枢支軸159を回動支点にバネ160によってブロッカ部161をメダル通路158より一時退避させる一時退避作用が働いて該ブロッカ部161はメダル通路158より一時的に退避する。このため、メダルMはメダル通路158内で押圧されずに済み、メダルMの通過は妨げられなくなり、メダル詰りが未然に解消される。   Further, when the medal M to be passed through the medal passage 158 descends, the pivot shaft 159 can be pivoted even when the blocker portion 161 is out of contact with the medal M due to the removal timing of the blocker portion 161 being shifted. The spring 160 temporarily retracts the blocker portion 161 from the medal passage 158 by the spring 160, and the blocker portion 161 is temporarily retracted from the medal passage 158. For this reason, the medal M does not need to be pressed in the medal passage 158, the passage of the medal M is not hindered, and the medal clogging is eliminated.

上述のように、メダルの飲込みを防止するバネ圧の高い応答性の排除ガイド機能を構成しても、メダル詰りや誤排除を誘起する押圧作用が生じようとするときは、ブロッカ部がメダルに押されてメダル通路に突出した状態から没する方向に一時退避し、該ブロッカ部を一時退避可能に設けることで、メダルの飲込み、詰り及び誤排除を防止することができる。   As described above, even if the responsive exclusion guide function with high spring pressure to prevent the swallowing of medals is configured, if a pressing action that induces clogging of medals or erroneous exclusion is about to occur, the blocker part is By temporarily retracting from the state of being pushed into the medal passage and sunk in the direction of sinking, and providing the blocker part so as to be able to be temporarily retracted, it is possible to prevent medals from being swallowed, clogged, and erroneously excluded.
