Description

硬貨処理装置Coin processing equipment
　本開示は、搬送面上で硬貨を搬送する搬送機構を備えた硬貨処理装置に関し、特に変形硬貨を排除する機構を備えた硬貨処理装置に関する。 The present disclosure relates to a coin processing device provided with a transport mechanism for transporting coins on a transport surface, and more particularly to a coin processing device provided with a mechanism for removing deformed coins.
　従来、硬貨入出金機や遊技機等に内蔵される硬貨処理装置において、変形した硬貨を排除するための技術が開示されている（例えば、特許文献１～２参照）。 Conventionally, a technique for removing a deformed coin in a coin processing apparatus built in a coin depositing / dispensing machine, a game machine, or the like has been disclosed (for example, see Patent Documents 1 and 2).
　特許文献１に記載の硬貨処理装置は、所定の厚さを有するメダルの中から厚み方向に変形した変形メダルを搬送通路外に排除するものである。この硬貨処理装置は、搬送通路上に通路開閉部材を備えており、通路開閉部材の内面に設けられた段差に変形メダルが当接すると、通路開閉部材の係合が解除されて開放され、変形メダルが排除される。 硬 The coin processing device described in Patent Literature 1 removes a deformed medal deformed in the thickness direction from a medal having a predetermined thickness to the outside of the transport path. This coin processing device is provided with a passage opening / closing member on the transport passage, and when the deformed medal comes into contact with a step provided on the inner surface of the passage opening / closing member, the engagement of the passage opening / closing member is released and released, and Medals are eliminated.
　特許文献２に記載の硬貨処理装置は、レーザ光を用いて変形コインの厚み変化を測定する厚み変化測定装置を備えており、厚み変化測定装置をコインが通過したとき、透光量が安定しなければ変形コインと判定する。そして、変形コインと判定された場合、排斥装置を駆動させて搬送路から排除口に切換え、変形コインを排除口に移動させて排除する。 The coin processing device described in Patent Literature 2 includes a thickness change measurement device that measures a change in thickness of a deformed coin using a laser beam. When a coin passes through the thickness change measurement device, the transmitted light amount becomes stable. If not, it is determined as a deformed coin. If it is determined that the coin is a deformed coin, the rejection device is driven to switch from the transport path to the elimination slot, and the deformed coin is moved to the elimination slot to be eliminated.

　特許文献１に記載の硬貨処理装置は、一定の厚さのメダルを対象としており、厚さや直径の異なる複数種類の硬貨には適用できない。また、変形メダルが段差に当接して通路開閉部材の係合を解除する構成であるため、変形メダルの搬送力により通路開閉部材の係合を解除するのに時間を要し、高速で連続搬送される硬貨から変形硬貨を排除するには確実性が乏しく、処理効率が悪い。 硬 The coin processing device described in Patent Document 1 is intended for medals of a certain thickness, and cannot be applied to a plurality of types of coins having different thicknesses and diameters. In addition, since the deformed medals come into contact with the steps to disengage the passage opening / closing members, it takes time to disengage the passage opening / closing members due to the conveying force of the deformed medals, and the continuous conveyance at high speed is required. There is little certainty in removing deformed coins from coins to be used, and processing efficiency is poor.
　特許文献２に記載の硬貨処理装置は、光学的手段を用いてコインの厚みの変化を検出し変形コインと判定した後に、排斥装置を駆動させて変形コインを排除している。このため、変形硬貨を判定する機構と変形硬貨を排除する機構とを別々に設ける必要があり、装置の大型化を招くと共に装置コストが嵩んでしまう。 The coin processing device described in Patent Document 2 detects a change in the thickness of the coin using optical means, determines that the coin is a deformed coin, and then drives the rejection device to remove the deformed coin. For this reason, it is necessary to separately provide a mechanism for determining a deformed coin and a mechanism for removing the deformed coin, which results in an increase in the size of the device and an increase in the device cost.
　そこで、簡便な構成で、複数種類の硬貨の中から変形硬貨を効率よく排除できる硬貨処理装置が望まれている。 Therefore, there is a demand for a coin processing device that can efficiently remove deformed coins from a plurality of types of coins with a simple configuration.
　本開示の一態様における硬貨処理装置の特徴構成は、搬送面上で硬貨を搬送する搬送機構と、前記搬送機構により搬送される硬貨の周縁部に当接して硬貨の搬送を案内する段差部と、搬送中の硬貨を前記段差部に向けて押付ける押付面を有する押付部と、を備え、前記段差部における硬貨の前記周縁部に当接する部位は、処理対象となる硬貨の最小の厚さよりも小さい高さであり、前記押付面は、硬貨の厚み方向に対して前記搬送面とは反対側である硬貨の周縁部上側に接触する傾斜部を有しており、前記搬送機構により搬送されている硬貨は、前記押付部により前記段差部に押付けられた状態で回転する点にある。 The characteristic configuration of the coin processing device according to an aspect of the present disclosure includes a transport mechanism that transports coins on a transport surface, and a step portion that guides the transport of coins by contacting the periphery of the coin transported by the transport mechanism. A pressing portion having a pressing surface for pressing the coin being conveyed toward the stepped portion, a portion of the stepped portion that abuts on the periphery of the coin is smaller than a minimum thickness of the coin to be processed. Is also small height, the pressing surface has an inclined portion that comes into contact with the upper side of the peripheral edge of the coin, which is opposite to the conveying surface with respect to the thickness direction of the coin, and is conveyed by the conveying mechanism. The coin is rotating while being pressed against the step by the pressing portion.
　本構成では、硬貨は押付部により段差部に向けて押付けられた状態で搬送されるので、硬貨は押付部と段差部との間に挟まれた状態で搬送される。その結果、押付部の押付力によって発生する硬貨の周縁部と段差部との間の搬送方向に沿う摩擦力により、搬送中の硬貨が回転する。このとき、本構成における押付部の押付面は、硬貨の周縁部上側に接触する傾斜部を有しているので、押付部から硬貨に作用する荷重の一部が、傾斜部により搬送面に向かう方向の分力と段差部へ向かう方向の分力とに変換される。 In this configuration, the coin is transported in a state where the coin is pressed toward the step portion by the pressing portion, and therefore, the coin is transported while being sandwiched between the pressing portion and the step portion. As a result, the coin being transported is rotated by the frictional force generated by the pressing force of the pressing portion between the peripheral portion of the coin and the stepped portion in the transport direction. At this time, since the pressing surface of the pressing portion in the present configuration has an inclined portion that comes into contact with the upper side of the peripheral edge of the coin, a part of the load acting on the coin from the pressing portion is directed to the transport surface by the inclined portion. This is converted into a component force in the direction and a component force in the direction toward the step.
　この搬送面に向かう方向の分力は搬送中の硬貨を搬送面に押付ける力となるため、硬貨と搬送面との間で摩擦力が発生し、硬貨に搬送機構の搬送力が適正に伝達された状態で硬貨が回転しながら搬送される。この回転しながら搬送されている途中にある硬貨が変形硬貨である場合、押付部により段差部に向けて押付けられている最中に、正常な硬貨に対して厚さ方向に変形して搬送面から離間した部位の周縁部上側に傾斜部が接触することがある。そして、硬貨が回転している最中に、上記搬送面に向かう方向の分力が、段差部と硬貨の周縁部との間で発生する硬貨を搬送面に押付ける方向の摩擦力を上回ったとき、変形硬貨の搬送面から離間した部位が搬送面に接近し、変形硬貨の段差部側の部位が浮き上がる。その結果、上記段差部に向かう方向の分力により、本構成のように処理対象となる硬貨の最小厚さよりも小さい高さである段差部を変形硬貨が乗り越え、変形硬貨を排除することが可能となる。一方、回転しながら搬送されている途中にある変形硬貨のうち搬送面に接触している部位の周縁部上側に傾斜部が接触し、変形硬貨の搬送面から離間した部位が段差部側にあるときには、上記段差部に向かう方向の分力により段差部を変形硬貨が乗り越え、変形硬貨が排除される。何れにしても、回転しながら搬送されている途中にある変形硬貨の搬送面から離間した部位が段差部側となり、該離間した部位と段差部とが当接していないときに、変形硬貨を排除することができる。 Since the component force in the direction toward the transport surface is a force pressing the coin being transported against the transport surface, a frictional force is generated between the coin and the transport surface, and the transport force of the transport mechanism is appropriately transmitted to the coin. The coins are conveyed while rotating in the state where the coins are rotated. If the coin being conveyed while being rotated is a deformed coin, the coin is deformed in the thickness direction with respect to a normal coin while being pressed toward the step by the pressing portion, and is conveyed. There is a case where the inclined portion comes in contact with the upper side of the peripheral portion of the portion separated from the upper portion. During the rotation of the coin, the component force in the direction toward the transport surface exceeded the frictional force in the direction pressing the coin generated between the step portion and the peripheral portion of the coin against the transport surface. At this time, a portion separated from the transport surface of the deformed coin approaches the transport surface, and a portion on the step portion side of the deformed coin rises. As a result, due to the component force in the direction toward the step, the deformed coin can climb over the step having a height smaller than the minimum thickness of the coin to be processed as in the present configuration, and the deformed coin can be eliminated. It becomes. On the other hand, among the deformed coins that are being conveyed while being rotated, the inclined portion contacts the upper side of the peripheral edge of the portion that is in contact with the transport surface, and the portion that is separated from the transport surface of the deformed coin is on the step side. At times, the deformed coin rides over the step due to the component force in the direction toward the step, and the deformed coin is removed. In any case, the part separated from the conveying surface of the deformed coin that is being conveyed while rotating is the step side, and the deformed coin is removed when the separated part does not abut on the step part. can do.
　このように、本構成では、押付部と段差部との間に硬貨を挟みながら、押付部の押圧面に設けた傾斜部を硬貨の周縁部上側に当接させる機構であるため、押圧面における傾斜部の範囲を所定の範囲に設定するだけで、厚さや直径の異なる複数種類の硬貨に対応すると共に、変形硬貨の排除基準を容易に変更することができる。しかも、変形硬貨を排除する機構のみで変形硬貨を自動的に排除することが可能であるため、変形硬貨を光学的手段で判定する機構を別途設ける必要がなく、効率的である。 As described above, in this configuration, while the coin is sandwiched between the pressing portion and the step portion, the inclined portion provided on the pressing surface of the pressing portion is brought into contact with the upper peripheral portion of the coin, so that the pressing surface has By simply setting the range of the inclined portion to a predetermined range, it is possible to cope with a plurality of types of coins having different thicknesses and diameters and easily change the criterion for removing deformed coins. In addition, since the deformed coin can be automatically removed only by the mechanism for removing the deformed coin, there is no need to separately provide a mechanism for determining the deformed coin by optical means, which is efficient.
　よって、押付部に傾斜部を設けるといった簡便な構成でありながら、複数種類の硬貨の中から変形硬貨を効率よく排除できる硬貨処理装置を提供できた。 Accordingly, a coin processing device capable of efficiently removing deformed coins from a plurality of types of coins can be provided while having a simple configuration in which an inclined portion is provided in the pressing portion.
　他の特徴構成は、前記搬送機構は、前記搬送面が回転円盤の表面で構成されており、前記段差部は、前記回転円盤の中央部において、前記搬送面に対して前記押付部側に突出した部位である点にある。 Another characteristic configuration is that, in the transport mechanism, the transport surface is formed of a surface of a rotating disk, and the step portion projects toward the pressing portion with respect to the transport surface at a central portion of the rotating disk. It is a point that has been done.
　本構成のように、回転円盤に段差部を設ければ、搬送機構と段差部とを回転円盤で兼用することとなるため、部品点数を節約して小型化を図りつつ装置コストを低減することができる。 If a rotating disk is provided with a stepped portion as in this configuration, the transport mechanism and the stepped portion can be shared by the rotating disk, so that the number of parts can be saved, the size can be reduced, and the device cost can be reduced. Can be.
　他の特徴構成は、前記回転円盤は、水平方向に対して傾斜した姿勢で回転し、前記搬送面は、硬貨に摩擦力を作用させる摩擦部位を有している点にある。 Another characteristic configuration is that the rotating disk rotates in a posture inclined with respect to the horizontal direction, and the transport surface has a friction portion for applying a frictional force to coins.
　本構成のように、回転円盤を傾斜させて搬送面に摩擦部位を設ければ、回転円盤が水平方向に対して傾斜した姿勢で下から上に向かって硬貨を搬送することが可能となり、回転円盤を水平に載置する場合に比べて、装置の水平方向の断面寸法を小さくすることができる。しかも、回転円盤が傾斜していることから、段差部から排除された硬貨が重力方向に自然落下するため、排除硬貨を回収ボックスに誘導する機構を別途設ける必要がなく効率的である。 If the rotating disk is tilted to provide frictional parts on the transport surface as in this configuration, it becomes possible to transport coins from the bottom to the top in a posture where the rotating disk is inclined with respect to the horizontal direction. The horizontal cross-sectional dimension of the device can be reduced as compared with the case where the disk is placed horizontally. In addition, since the rotating disc is inclined, the coin removed from the step falls naturally in the direction of gravity, so that there is no need to separately provide a mechanism for guiding the removed coin to the collection box, which is efficient.
　他の特徴構成は、前記搬送機構は、本体部と当該本体部から突出し硬貨を押動する突出部とを有する無端状回転体を備えており、前記段差部は、直線状に形成されている点にある。 Another characteristic configuration is that the transport mechanism includes an endless rotating body having a main body and a protruding portion that protrudes from the main body and pushes a coin, and the step portion is formed in a linear shape. On the point.
　本構成のように、搬送機構を無端状回転体で構成して段差部を直線状に形成しても変形硬貨が排除可能となるため、設計自由度が高まる。 し て も As in the present configuration, even if the transport mechanism is formed of an endless rotating body and the stepped portion is formed in a straight line, deformed coins can be eliminated, thereby increasing the degree of freedom in design.
　他の特徴構成は、前記押付部は、前記突出部に形成されている点にある。 特 徴 Another characteristic configuration is that the pressing portion is formed on the protruding portion.
　本構成のように押付部が突出部に形成されていれば、別途押付部の機構を設ける必要がないため、部品点数を節約して小型化を図りつつ装置コストを低減することができる。 (4) If the pressing portion is formed on the protruding portion as in this configuration, it is not necessary to provide a separate mechanism for the pressing portion. Therefore, it is possible to reduce the number of components, reduce the size, and reduce the apparatus cost.

　ベース部材３１は、板状の部材であって、硬貨繰出装置３０の各構成要素が取り付けられる基台である。回転円盤３２は、地面と平行な方向である水平方向に対して傾斜した姿勢で回転する円盤であって、硬貨を回転円盤３２の下部領域から上部領域へ搬送する。すなわち、回転円盤３２は、上面に接触した硬貨を入金搬送部２０へ向けて搬送する。 The base member 31 is a plate-like member, and is a base to which each component of the coin feeding device 30 is attached. The rotating disk 32 is a disk that rotates in a posture inclined with respect to a horizontal direction parallel to the ground, and conveys coins from a lower region of the rotating disk 32 to an upper region. That is, the rotating disk 32 conveys the coins that have come into contact with the upper surface toward the deposit conveyance unit 20.
　カバー部材３５は、回転円盤３２の下部領域を覆う部材であって、回転円盤３２との間に硬貨貯留空間３６を形成している（図２，図４～図６参照）。硬貨貯留空間３６は、硬貨受入口１４から送られた硬貨を貯留する空間であって、回転円盤３２とカバー部材３５との間に形成される空間である。 The cover member 35 is a member that covers the lower region of the rotating disk 32, and forms a coin storage space 36 with the rotating disk 32 (see FIGS. 2, 4 to 6). The coin storage space 36 is a space for storing coins sent from the coin receiving port 14 and is a space formed between the rotating disk 32 and the cover member 35.
　外周ベルト３７は、回転円盤３２の下部領域の硬貨と接触して、回転円盤３２による硬貨の搬送を補助する。案内部材３８の内面３８ａは、回転円盤３２上の硬貨と接触して入金搬送部２０へと案内する。レバー部材３９は、回転円盤３２による硬貨の搬送方向の下流側に配置され、搬送中の硬貨を後述する段差部３２ｄに向けて押付けて移動させる。 (4) The outer peripheral belt 37 comes into contact with coins in a lower region of the rotating disk 32 and assists the transport of coins by the rotating disk 32. The inner surface 38 a of the guide member 38 comes into contact with the coins on the rotating disk 32 and guides the coin to the deposit transfer section 20. The lever member 39 is disposed downstream of the rotating disk 32 in the direction in which coins are conveyed, and pushes and moves the coin being conveyed toward a step portion 32d described later.
　回転円盤３２は、摩擦部位３２ｃおよび段差部３２ｄを有している。回転円盤３２は、摩擦部位３２ｃの表面（搬送面の一例）がベース部材３１の上面と平行となるように配置されている。回転円盤３２の回転軸３２ａは、ベース部材３１と垂直に配置されており、モータ等（不図示）の駆動力により回転軸３２ａを中心に回転する。 The rotating disk 32 has a friction portion 32c and a step 32d. The rotating disk 32 is arranged such that the surface of the friction portion 32 c (an example of a transfer surface) is parallel to the upper surface of the base member 31. The rotating shaft 32a of the rotating disk 32 is arranged perpendicular to the base member 31, and rotates about the rotating shaft 32a by a driving force of a motor or the like (not shown).
　回転円盤３２の傾斜角度（地面に対する角度）に関し、傾斜角度が大きいほど、異物が回転円盤３２の上部領域に到達し難くなり異物の排除能力が向上するが、硬貨の搬送も困難になる。回転円盤３２の傾斜角度は３５°以上が好ましく、３５°以上４０°以下が好適である。 Regarding the inclination angle of the rotating disk 32 (the angle with respect to the ground), the larger the inclination angle, the more difficult it is for foreign matter to reach the upper region of the rotating disk 32, and the more the foreign matter elimination ability is improved. The inclination angle of the rotating disk 32 is preferably 35 ° or more, and more preferably 35 ° or more and 40 ° or less.
　摩擦部位３２ｃは、回転円盤３２の表面に形成された円環状の部位である。摩擦部位３２ｃの幅は、硬貨入金機１０の処理対象となる複数種類の硬貨の最大直径よりも大きい。摩擦部位３２ｃは、硬貨に摩擦力を作用させる部位であって、具体的には、回転円盤３２の表面にゴムや樹脂等が貼り付けられて形成されている。 The friction portion 32c is an annular portion formed on the surface of the rotating disk 32. The width of the friction portion 32c is larger than the maximum diameter of a plurality of types of coins to be processed by the coin depositing machine 10. The friction portion 32c is a portion for applying a frictional force to a coin, and is specifically formed by attaching rubber, resin, or the like to the surface of the rotating disk 32.
　段差部３２ｄは、回転円盤３２の中央部において、摩擦部位３２ｃの径方向内側に形成され、摩擦部位３２ｃの表面に対して上側（搬送面に対してレバー部材３９が位置する側）に突出した部位である。この段差部３２ｄは、円盤状の薄板部材を、その中心軸が回転円盤３２の回転軸３２ａと一致するように回転円盤３２の上面に取り付けられて固定されている。段差部３２ｄの外周面３２ｅと、回転円盤３２の外周３２ｂとは、いずれも回転円盤３２の回転軸３２ａを中心とする円形状であり、回転円盤３２の回転に伴って段差部３２ｄが一体的に回転する。 The step portion 32d is formed radially inward of the friction portion 32c at the center of the rotating disk 32 and protrudes upward with respect to the surface of the friction portion 32c (on the side where the lever member 39 is located with respect to the transport surface). Part. The step portion 32d is attached and fixed to the upper surface of the rotating disk 32 such that a disk-shaped thin plate member has its central axis coincident with the rotating shaft 32a of the rotating disk 32. The outer peripheral surface 32e of the step portion 32d and the outer periphery 32b of the rotating disk 32 are both circular with the rotation axis 32a of the rotating disk 32 as the center. The step portion 32d is integrated with the rotation of the rotating disk 32. To rotate.
　段差部３２ｄの外周近傍に傾斜部位３２ｆが形成されており（図４参照）、段差部３２ｄ上面の外周側はテーパ状となっている。段差部３２ｄの外周面３２ｅの上端と摩擦部位３２ｃの表面との距離（段差部３２ｄにおける硬貨の周縁部に当接する部位の高さ）は、処理対象となる複数種類の硬貨の最小の厚さより小さい。そうすると、複数種類の硬貨のうち厚さが最小の硬貨が２枚、回転円盤３２の上で重なって搬送され、段差部３２ｄに接触した場合には、下側の硬貨すなわち回転円盤３２の上面（摩擦部位３２ｃの表面）に接触している硬貨のみが段差部３２ｄの外周面３２ｅに当接し、他方の硬貨（硬貨の上に重なっている硬貨）は、段差部３２ｄの外周面３２ｅに接触しない。これにより、重送硬貨Ｃ３の捌きを適切に行うことが可能となる（図７参照）。 (4) An inclined portion 32f is formed near the outer periphery of the step portion 32d (see FIG. 4), and the outer peripheral side of the upper surface of the step portion 32d is tapered. The distance between the upper end of the outer peripheral surface 32e of the step portion 32d and the surface of the friction portion 32c (the height of the portion of the step portion 32d that contacts the peripheral edge of the coin) is smaller than the minimum thickness of a plurality of types of coins to be processed. small. Then, two coins having the smallest thickness among the plurality of types of coins are conveyed while being superimposed on the rotating disk 32 and come into contact with the stepped portion 32d, and the lower coin, that is, the upper surface of the rotating disk 32 ( Only coins that are in contact with the frictional portion 32c) come into contact with the outer peripheral surface 32e of the step 32d, and the other coin (coin superimposed on the coin) does not contact the outer peripheral surface 32e of the step 32d. . This makes it possible to appropriately handle the multi-feed coin C3 (see FIG. 7).
　図３～図６に示すように、カバー部材３５は、開閉部位３５ａ、軸部材３５ｂおよび押圧部材３５ｃを有して構成され、付勢機構３５ｄを介してベース部材３１に取り付けられている。付勢機構３５ｄの支柱はベース部材３１に設けられ、バネを介して支柱に取り付けられた板状部材が、カバー部材３５を回転円盤３２に向けて付勢している。 As shown in FIGS. 3 to 6, the cover member 35 includes an opening / closing portion 35a, a shaft member 35b, and a pressing member 35c, and is attached to the base member 31 via an urging mechanism 35d. The column of the urging mechanism 35d is provided on the base member 31, and a plate-like member attached to the column via a spring urges the cover member 35 toward the rotating disk 32.
　押圧部材３５ｃは板状の部材であって、回転円盤３２およびカバー部材３５の外周の円弧に沿う形状に形成されている。押圧部材３５ｃは、その外周の円弧がカバー部材３５の外周に沿う姿勢で、且つ、回転円盤３２の摩擦部位３２ｃに対向する位置にて、カバー部材３５の回転円盤３２に対向する面に取り付けられている。 The pressing member 35c is a plate-like member, and is formed in a shape along an arc on the outer circumference of the rotating disk 32 and the cover member 35. The pressing member 35c is attached to the surface of the cover member 35 facing the rotating disk 32 at a position where the arc of the outer circumference is along the outer circumference of the cover member 35 and at a position facing the friction portion 32c of the rotating disk 32. ing.
　このようにカバー部材３５は付勢機構３５ｄにより回転円盤３２に向けて付勢されている。図４に示すように押圧部材３５ｃと回転円盤３２の摩擦部位３２ｃとの間に硬貨が入り込むと、押圧部材３５ｃが硬貨を回転円盤３２の摩擦部位３２ｃの表面に押し付けることになる。その結果、硬貨と摩擦部位３２ｃの表面との間の摩擦力が増加して、回転円盤３２による硬貨の搬送が確実に行われることになる。これにより、硬貨貯留空間３６に少数の硬貨が存在する場合であっても、硬貨の繰り出しが確実に行われて、硬貨繰出装置３０に繰り出されない硬貨が残留する事態を抑制することができる。また、硬貨と摩擦部位３２ｃの表面との間の摩擦力が増加するから、回転円盤３２の回転速度を増加させることが可能となる。 Thus, the cover member 35 is urged toward the rotating disk 32 by the urging mechanism 35d. As shown in FIG. 4, when a coin enters between the pressing member 35 c and the friction portion 32 c of the rotating disk 32, the pressing member 35 c presses the coin against the surface of the friction portion 32 c of the rotating disk 32. As a result, the frictional force between the coin and the surface of the friction portion 32c increases, and the transport of the coin by the rotating disk 32 is ensured. Thus, even when a small number of coins are present in the coin storage space 36, coins are reliably fed out, and a situation in which coins that are not fed out to the coin feeding device 30 remain can be suppressed. Further, since the frictional force between the coin and the surface of the frictional portion 32c increases, the rotation speed of the rotating disk 32 can be increased.
　開閉部位３５ａは、カバー部材３５に形成された部位であって、開閉することにより、硬貨貯留空間３６の内部の異物Ｅ（例えば、クリップ、カギや変形硬貨など）を硬貨貯留空間３６の外部に排出することができる（図５～図６参照）。本実施形態の開閉部位３５ａは、軸部材３５ｂを介してカバー部材３５に取り付けられており、不図示のソレノイド等により駆動されて軸部材３５ｂの回りに回動し、開閉の動作を行う。開閉部位３５ａの開閉による硬貨貯留空間３６からの異物Ｅの排出は、硬貨貯留空間３６の内部に正常硬貨（変形していない硬貨）が貯留されていない際に行われる。例えば、硬貨貯留空間３６の内部の正常硬貨の有無を検知する不図示のセンサを硬貨繰出装置３０に設け、制御部８０が当該センサの出力に基づいて開閉部位３５ａの開閉を制御する。例えば制御部８０は、センサが正常硬貨を検知していない際に、開閉部位３５ａを開操作する（図６参照）。これにより硬貨貯留空間３６の内部に異物があった場合には、当該異物は排出される。 The opening / closing portion 35 a is a portion formed on the cover member 35, and by opening and closing, the foreign matter E (for example, a clip, a key, a deformed coin, or the like) inside the coin storage space 36 is moved outside the coin storage space 36. It can be discharged (see FIGS. 5 and 6). The opening / closing portion 35a according to the present embodiment is attached to the cover member 35 via a shaft member 35b, and is rotated around the shaft member 35b by being driven by a solenoid (not shown) or the like to perform opening / closing operations. Discharge of the foreign matter E from the coin storage space 36 by opening and closing the opening / closing portion 35a is performed when normal coins (undeformed coins) are not stored in the coin storage space 36. For example, a sensor (not shown) for detecting the presence or absence of a normal coin inside the coin storage space 36 is provided in the coin feeding device 30, and the control unit 80 controls the opening and closing of the opening and closing portion 35a based on the output of the sensor. For example, when the sensor does not detect a normal coin, the controller 80 opens the opening / closing portion 35a (see FIG. 6). Thus, if there is a foreign substance inside the coin storage space 36, the foreign substance is discharged.
　図３～図４に示すように、外周ベルト３７は、回転円盤３２の下部領域の硬貨と接触して、回転円盤３２による硬貨の搬送を補助する。外周ベルト３７は、その搬送面が回転円盤３２の外周３２ｂに対向する姿勢にて、回転円盤３２の下部領域において回転円盤３２に隣接して配置されている。 3) As shown in FIGS. 3 and 4, the outer peripheral belt 37 contacts the coins in the lower region of the rotating disk 32 and assists the transport of the coins by the rotating disk 32. The outer peripheral belt 37 is disposed adjacent to the rotating disk 32 in a lower region of the rotating disk 32 in a posture in which a transport surface thereof faces the outer periphery 32 b of the rotating disk 32.
　この外周ベルト３７は平ベルトであって、３つの外周プーリー３７ａの周囲に巻き回されている。３つの外周プーリー３７ａは自由に回転可能である。外周ベルト３７は、回転円盤３２の近傍では、ベース部材３１の周壁３１ａと回転円盤３２との間に、回転円盤３２の外周３２ｂに接触する状態で配置されている。回転円盤３２が回転すると、外周ベルト３７は、回転円盤３２と接触した状態のまま、回転円盤３２と共に移動する。 外 周 The outer peripheral belt 37 is a flat belt and is wound around three outer peripheral pulleys 37a. The three outer pulleys 37a are freely rotatable. The outer peripheral belt 37 is disposed between the peripheral wall 31a of the base member 31 and the rotating disk 32 in the vicinity of the rotating disk 32 so as to be in contact with the outer periphery 32b of the rotating disk 32. When the rotating disk 32 rotates, the outer peripheral belt 37 moves together with the rotating disk 32 while being in contact with the rotating disk 32.
　摩擦部位３２ｃ上の硬貨は、その周縁部が外周ベルト３７と接触した状態で、回転円盤３２によって搬送される。このとき外周ベルト３７は回転円盤３２と同期して走行し、硬貨と共に回転円盤３２の上部領域へと移動する。よって、硬貨は回転円盤３２の摩擦部位３２ｃと外周ベルト３７との両方から力を受けて、回転円盤３２の上部領域へ搬送される。 硬 The coin on the friction portion 32c is conveyed by the rotating disk 32 in a state where the peripheral edge thereof is in contact with the outer peripheral belt 37. At this time, the outer peripheral belt 37 runs in synchronization with the rotating disk 32 and moves to the upper region of the rotating disk 32 together with coins. Accordingly, the coin receives a force from both the friction portion 32 c of the rotating disk 32 and the outer peripheral belt 37 and is conveyed to an upper region of the rotating disk 32.
　図３に示すように、レバー部材３９は、摩擦部位３２ｃの上の硬貨と接触して、硬貨を段差部３２ｄに向けて押付けて移動させる。このレバー部材３９は、弧状に湾曲した部材であって、軸３９ａの回りに回転可能な状態で、一方の端部がベース部材３１に取り付けられている。そして、レバー部材３９の他方の端部が、回転円盤３２の摩擦部位３２ｃ上に位置する状態で配置されている。レバー部材３９にはバネ３９ｂが接続されており、レバー部材３９が摩擦部位３２ｃ上の硬貨に当接して回転円盤３２の径方向外側へ向けて変位すると、バネ３９ｂがレバー部材３９を回転円盤３２の径方向内側へ向けて付勢する。 (3) As shown in FIG. 3, the lever member 39 comes into contact with the coin on the friction portion 32c and presses and moves the coin toward the step portion 32d. The lever member 39 is a member curved in an arc shape, and has one end attached to the base member 31 so as to be rotatable around a shaft 39a. The other end of the lever member 39 is arranged so as to be located on the friction portion 32c of the rotating disk 32. A spring 39b is connected to the lever member 39, and when the lever member 39 contacts the coin on the friction portion 32c and is displaced radially outward of the rotating disk 32, the spring 39b causes the lever member 39 to rotate the rotating disk 32. Urges radially inward.
　回転円盤３２により搬送される硬貨は、遠心力によって、図７に示す硬貨のように回転円盤３２の外周寄りに位置して搬送される。そのような硬貨がレバー部材３９に接触すると、レバー部材３９によって回転円盤３２の内側へ向けて移動され、硬貨の周縁部が回転円盤３２の段差部３２ｄに当接する。 (7) The coin conveyed by the rotating disk 32 is conveyed near the outer periphery of the rotating disk 32 due to the centrifugal force, like the coin shown in FIG. When such a coin comes into contact with the lever member 39, the coin is moved toward the inside of the rotating disk 32 by the lever member 39, and the periphery of the coin comes into contact with the step portion 32d of the rotating disk 32.
　図７に示す並送硬貨Ｃ１は隣接する硬貨に引っ掛かって搬送されているが、この位置を越えると重力の作用で下方に落下して、硬貨貯留空間３６に戻される可能性が高い。正常硬貨Ｃ２はレバー部材３９と接触し、レバー部材３９によって段差部３２ｄに向けて移動している。このとき、レバー部材３９は、正常硬貨Ｃ２に押されて上方に変位している。重送硬貨Ｃ３は、レバー部材３９と接触して段差部３２ｄに向けて移動するが、正常硬貨Ｃ２と重なっていることから段差部３２ｄに引っ掛からず、重力の作用により下方に落下して、硬貨貯留空間３６に戻される。このようにして硬貨繰出装置３０のレバー部材３９および段差部３２ｄによって重送硬貨の捌きが行われると共に、回転円盤３２の径方向に並んだ硬貨も一列状態にすることができ、入金搬送部２０への一層一列状態での硬貨の繰り出しが実現される。 並 The parallel coin C1 shown in FIG. 7 is conveyed by being hooked on an adjacent coin. However, when the coin C1 exceeds this position, it is highly likely that the coin will fall downward by the action of gravity and be returned to the coin storage space 36. The normal coin C2 comes into contact with the lever member 39 and is moved toward the step portion 32d by the lever member 39. At this time, the lever member 39 is displaced upward by being pushed by the normal coin C2. The double-fed coin C3 comes into contact with the lever member 39 and moves toward the stepped portion 32d. However, since the coin C3 overlaps with the normal coin C2, the coin C3 does not get caught on the stepped portion 32d and falls downward by the action of gravity, and is dropped. It is returned to the storage space 36. In this manner, the multi-feed coins are separated by the lever member 39 and the step portion 32d of the coin feeding device 30, and the coins arranged in the radial direction of the rotating disk 32 can be arranged in a line. Coins are fed out in a single row.
　さらに、本実施形態では、図８に示すように、レバー部材３９の側面には、搬送中の硬貨を段差部３２ｄに向けて押付ける押付面３９ｃが形成されている。この押付面３９ｃは、搬送面となる摩擦部位３２ｃの表面から離間するに連れて段差部３２ｄに近付く方向に傾斜する傾斜部３９ｃ１を有している。この傾斜部３９ｃ１は、摩擦部位３２ｃの表面に対する垂線に対して所定の傾斜角θ（例えば、３０度）を有した同一平面上に形成されている。これにより、傾斜部３９ｃ１は、正常硬貨Ｃ２の厚み方向に対して摩擦部位３２ｃの表面（搬送面）とは反対側である正常硬貨Ｃ２の周縁部上側に接触している。 Further, in the present embodiment, as shown in FIG. 8, on the side surface of the lever member 39, a pressing surface 39c for pressing the coin being conveyed toward the step portion 32d is formed. The pressing surface 39c has an inclined portion 39c1 that is inclined in a direction approaching the step portion 32d as the distance from the surface of the friction portion 32c serving as the transport surface increases. The inclined portion 39c1 is formed on the same plane having a predetermined inclined angle θ (for example, 30 degrees) with respect to a perpendicular to the surface of the friction portion 32c. Thus, the inclined portion 39c1 is in contact with the upper side of the peripheral edge of the normal coin C2, which is on the opposite side to the surface (transport surface) of the friction portion 32c in the thickness direction of the normal coin C2.
　バネ３９ｂの付勢力により、レバー部材３９が回転円盤３２の上面と平行な方向に発生するレバー荷重Ｆのうち硬貨に作用する分力（以下、単に「レバー荷重Ｆの分力」とも称する）は、段差部３２ｄに向かう段差部押付力Ｆ１（＝Ｆｃｏｓ２θ）と、正常硬貨Ｃ２を摩擦部位３２ｃの表面に押付ける搬送面押付力Ｆ２（＝Ｆｓｉｎθｃｏｓθ）とを含んでいる。段差部押付力Ｆ１は、正常硬貨Ｃ２を段差部３２ｄの外周面３２ｅと正常硬貨Ｃ２の周縁部とが摺接する摩擦力を発生させ、これにより、時計回りに回転している回転円盤３２に対して、反時計回りに正常硬貨Ｃ２が回転しながら搬送される（図７参照）。このとき、レバー荷重Ｆの一部が、搬送面である摩擦部位３２ｃの表面に向かう方向の搬送面押付力Ｆ２へと変換されているので、正常硬貨Ｃ２が摩擦部位３２ｃの表面に押付けられて摩擦力が発生し、回転円盤３２の搬送力が摩擦部位３２ｃを介して正常硬貨Ｃ２に確実に伝達される。その結果、正常硬貨Ｃ２が回転する際に摩擦部位３２ｃの表面を滑ることなく、搬送不良となることを防止できる。 Of the lever load F generated by the lever member 39 in a direction parallel to the upper surface of the rotating disk 32 due to the urging force of the spring 39b, the component force acting on the coin (hereinafter, also simply referred to as the "component force of the lever load F") is And a step pressing force F1 (= Fcos 2 θ) toward the step 32d, and a transport surface pressing force F2 (= Fsin θcos θ) that presses the normal coin C2 against the surface of the friction portion 32c. The step pressing force F1 generates a frictional force in which the normal coin C2 slides between the outer peripheral surface 32e of the step 32d and the peripheral edge of the normal coin C2, thereby causing the rotating disk 32 rotating clockwise. Thus, the normal coin C2 is conveyed while rotating counterclockwise (see FIG. 7). At this time, since a part of the lever load F has been converted into the transfer surface pressing force F2 in the direction toward the surface of the friction portion 32c which is the transfer surface, the normal coin C2 is pressed against the surface of the friction portion 32c. A friction force is generated, and the conveyance force of the rotating disk 32 is reliably transmitted to the normal coin C2 via the friction portion 32c. As a result, when the normal coin C2 rotates, slippage on the surface of the frictional portion 32c can be prevented, and a transportation failure can be prevented.
　続いて、図９～図１０を用いて、正常硬貨に対して厚み方向に変形した変形硬貨Ｃ４を排除する機構について説明する。図９に示すように、回転しながら搬送されている途中にある変形硬貨Ｃ４がレバー部材３９に接触したとき、中央を境にしてレバー部材３９の側が摩擦部位３２ｃの表面から離間するように折れ曲がり、この折れ曲がった部位の周縁部上側が傾斜部３９ｃ１に接触しているとする。上述したように、レバー荷重Ｆの分力は、段差部押付力Ｆ１と搬送面押付力Ｆ２とを含んでいるので、段差部押付力Ｆ１により変形硬貨Ｃ４が段差部３２ｄの外周面３２ｅに押付けられ、搬送面押付力Ｆ２により変形硬貨Ｃ４の折れ曲がった部位を摩擦部位３２ｃの表面に押付ける力が作用する。そして、変形硬貨Ｃ４のレバー部材３９の側が摩擦部位３２ｃの表面から離間しているので、段差部３２ｄの外周面３２ｅに押し付けられている側では、変形硬貨Ｃ４が摩擦部位３２ｃの表面から離間しようとする力が作用し、その力と逆方向の摩擦力Ｆｍが発生している。そして、変形硬貨Ｃ４が回転するにつれて、搬送面押付力Ｆ２は変化しないが、段差部３２ｄの外周面３２ｅに押し付けられている側が摩擦部位３２ｃの表面から離間し始めると、変形硬貨Ｃ４を摩擦部位３２ｃの表面に押付ける方向の摩擦力Ｆｍは減少する。搬送面押付力Ｆ２が、段差部３２ｄの外周面３２ｅと変形硬貨Ｃ４の周縁部との間で発生する摩擦力のうち、変形硬貨Ｃ４を摩擦部位３２ｃの表面に押付ける方向の摩擦力Ｆｍを上回ったとき、搬送中の変形硬貨Ｃ４の段差部３２ｄ側の部位が更に浮き上がり、最終的に搬送中の変形硬貨Ｃ４の周縁部と段差部３２ｄの外周面３２ｅとの当接が解除される（図１０参照）。このとき、段差部押付力Ｆ１により、変形硬貨Ｃ４が段差部３２ｄの傾斜部位３２ｆを乗り越え、径方向内側に押し出される。また、段差部３２ｄに傾斜部位３２ｆを設けているため、変形硬貨Ｃ４の段差部３２ｄに対する乗り越えが円滑となる。そして、変形硬貨Ｃ４は、重力の作用により下方に落下して、硬貨貯留空間３６に戻される。 Next, a mechanism for removing a deformed coin C4 deformed in the thickness direction from a normal coin will be described with reference to FIGS. As shown in FIG. 9, when the deformed coin C4 that is being conveyed while rotating contacts the lever member 39, the deformed coin C4 is bent such that the side of the lever member 39 is separated from the surface of the friction portion 32c from the center. It is assumed that the upper edge of the bent portion is in contact with the inclined portion 39c1. As described above, since the component force of the lever load F includes the step pressing force F1 and the transfer surface pressing force F2, the deformed coin C4 is pressed against the outer peripheral surface 32e of the step 32d by the step pressing force F1. Then, a force for pressing the bent portion of the deformed coin C4 against the surface of the friction portion 32c is applied by the transfer surface pressing force F2. Since the side of the lever member 39 of the deformed coin C4 is separated from the surface of the frictional portion 32c, the side of the deformed coin C4 that is pressed against the outer peripheral surface 32e of the step portion 32d will separate from the surface of the frictional portion 32c. Is applied, and a frictional force Fm in a direction opposite to the force is generated. Then, as the deformed coin C4 rotates, the conveying surface pressing force F2 does not change, but when the side of the step portion 32d pressed against the outer peripheral surface 32e begins to separate from the surface of the friction portion 32c, the deformed coin C4 is moved to the friction portion. The frictional force Fm in the direction of pressing against the surface of 32c decreases. The transfer surface pressing force F2 is the frictional force Fm in the direction of pressing the deformed coin C4 against the surface of the friction portion 32c among the frictional force generated between the outer peripheral surface 32e of the step 32d and the peripheral edge of the deformed coin C4. When it exceeds, the portion on the side of the step portion 32d of the deformed coin C4 being conveyed further rises, and finally, the contact between the peripheral edge portion of the deformed coin C4 being conveyed and the outer peripheral surface 32e of the step portion 32d is released ( (See FIG. 10). At this time, the deformed coin C4 gets over the inclined portion 32f of the step portion 32d and is pushed radially inward by the step pressing force F1. In addition, since the inclined portion 32f is provided in the step portion 32d, the deformed coin C4 can pass over the step portion 32d smoothly. Then, the deformed coin C4 falls downward by the action of gravity and returns to the coin storage space 36.
　一方、図１０に示すように、回転しながら搬送されている途中にある変形硬貨Ｃ４のうち摩擦部位３２ｃの表面に接触している部位の周縁部上側に傾斜部３９ｃ１が接触し、変形硬貨Ｃ４の折れ曲がった部位が段差部３２ｄ側にあるとする。この場合、変形硬貨Ｃ４が回転しなくても変形硬貨Ｃ４の周縁部と段差部３２ｄの外周面３２ｅとが当接していないので、段差部押付力Ｆ１により、変形硬貨Ｃ４が段差部３２ｄの傾斜部位３２ｆを乗り越え、径方向内側に押し出される。何れにしても、回転しながら搬送されている途中にある変形硬貨Ｃ４のうち、摩擦部位３２ｃの表面から離間した部位が段差部３２ｄ側となり、変形硬貨Ｃ４の周縁部と段差部３２ｄの外周面３２ｅとの当接が解除されたとき、変形硬貨Ｃ４を排除することができる。なお、変形硬貨Ｃ４に対して変形方向が逆方向に変形している（山部が上側になっている）変形硬貨については、山部に該当する硬貨周縁が段差部３２ｄの外周面３２ｅより高い位置にあるため、硬貨が回転しながら搬送されるだけで変形硬貨Ｃ４の周縁部（山部）と段差部３２ｄの外周面３２ｅとの当接が解除されて変形硬貨Ｃ４を排除することができる。また、仮に変形硬貨Ｃ４の変形量が小さい場合であっても、上述のようにレバー部材３９の傾斜部３９ｃ１の作用により変形硬貨Ｃ４の段差部３２ｄ側の部位が更に浮き上がり、変形硬貨Ｃ４の周縁部と段差部３２ｄの外周面３２ｅとの当接が解除されることにより、変形硬貨Ｃ４を確実に排除することができる。 On the other hand, as shown in FIG. 10, the inclined portion 39c1 comes into contact with the upper side of the peripheral portion of the portion of the deformed coin C4 that is being conveyed while rotating and is in contact with the surface of the friction portion 32c, and the deformed coin C4 Is located on the side of the step portion 32d. In this case, even if the deformed coin C4 does not rotate, the peripheral edge of the deformed coin C4 does not contact the outer peripheral surface 32e of the stepped portion 32d, so that the deformed coin C4 is inclined by the stepped portion pressing force F1. It gets over the part 32f and is pushed radially inward. In any case, among the deformed coins C4 that are being conveyed while being rotated, the portion separated from the surface of the frictional portion 32c is the step portion 32d side, and the peripheral edge portion of the deformed coin C4 and the outer peripheral surface of the step portion 32d. When the contact with 32e is released, the deformed coin C4 can be eliminated. Note that, with respect to the deformed coin whose deformation direction is deformed in the opposite direction to the deformed coin C4 (the peak is on the upper side), the periphery of the coin corresponding to the peak is higher than the outer peripheral surface 32e of the step portion 32d. Since the coin is located at the position, the contact between the peripheral edge (mountain) of the deformed coin C4 and the outer peripheral surface 32e of the stepped portion 32d is released only by being conveyed while rotating, and the deformed coin C4 can be removed. . Even if the amount of deformation of the deformed coin C4 is small, the portion of the deformed coin C4 on the side of the step portion 32d further rises due to the action of the inclined portion 39c1 of the lever member 39 as described above, and the periphery of the deformed coin C4 The deformed coin C4 can be reliably removed by releasing the contact between the portion and the outer peripheral surface 32e of the step portion 32d.
　このように、レバー部材３９と段差部３２ｄとの間に硬貨を挟みながら、レバー部材３９の押付面３９ｃに設けた傾斜部３９ｃ１を硬貨の周縁部上側に当接させる機構であるため、押付面３９ｃにおける傾斜部３９ｃ１の範囲、傾斜角度、バネ３９ｂの弾性力を所定の範囲に設定するだけで、厚さや直径の異なる複数種類の硬貨に対応すると共に、変形硬貨の排除基準を容易に変更することができる。例えば、変形度合いの小さい変形硬貨も排除したい場合には、傾斜部３９ｃ１の傾斜角度を大きくするといった具合に変形硬貨の排除基準を変更することができる。しかも、変形硬貨を排除する機構のみで変形硬貨を自動的に排除することが可能であるため、変形硬貨を光学的手段で判定する機構を別途設ける必要がなく、効率的である。 As described above, since the coin is sandwiched between the lever member 39 and the step portion 32d, the inclined portion 39c1 provided on the pressing surface 39c of the lever member 39 is brought into contact with the upper side of the periphery of the coin. By simply setting the range of the inclined portion 39c1 in 39c, the angle of inclination, and the elastic force of the spring 39b to predetermined ranges, it is possible to cope with a plurality of types of coins having different thicknesses and diameters and easily change the exclusion criteria for deformed coins. be able to. For example, when it is desired to also remove a deformed coin having a small degree of deformation, the exclusion criterion of the deformed coin can be changed, for example, by increasing the inclination angle of the inclined portion 39c1. In addition, since the deformed coin can be automatically removed only by the mechanism for removing the deformed coin, there is no need to separately provide a mechanism for determining the deformed coin by optical means, which is efficient.

In the first embodiment, the transport mechanism is configured by the rotating disk 32, the transport surface is configured by the surface of the rotating disk 32 (the surface of the friction portion 32 c), and the step 32 d is formed in the center of the rotating disk 32 by a disk-shaped thin plate. It was composed of members. Instead of this, in the present embodiment, as shown in FIGS. 11 to 13, the transport mechanism is configured by an endless belt 5 (an example of an endless rotating body), and the step portion 6 is configured to be linear in the transport direction D. are doing. Further, the transport surface is constituted by a horizontal transport surface 7 that is horizontal to the ground, and a reject mechanism 8 that transports the deformed coins that have climbed over the step 6 to the reject hole 82 is provided. As in the first embodiment, the lever member 39 (an example of a pressing portion) presses the coin being transported toward the step portion 6.
　無端ベルト５は、不図示のプーリーに巻回される本体部５１と、本体部５１から突出し硬貨を押動する複数のピン状部材５２（突出部の一例）とを有している。複数のピン状部材５２は、夫々が無端ベルト５の周方向に沿って等間隔となるように本体部５１に固定されている。夫々のピン状部材５２の下端（端部）は、処理対象となる複数種類の硬貨の最小の厚さより小さい距離で水平搬送面７から離間している。夫々のピン状部材５２は、硬貨の周縁部に接触して搬送方向Ｄに沿って水平搬送面７上の硬貨を１枚ずつ搬送する。 The endless belt 5 has a main body 51 wound around a pulley (not shown), and a plurality of pin-shaped members 52 (an example of a protruding portion) that protrude from the main body 51 and push coins. The plurality of pin-shaped members 52 are fixed to the main body 51 so as to be spaced at equal intervals along the circumferential direction of the endless belt 5. The lower ends (ends) of the respective pin-shaped members 52 are separated from the horizontal transport surface 7 by a distance smaller than the minimum thickness of a plurality of types of coins to be processed. Each of the pin-shaped members 52 comes into contact with the periphery of the coin and conveys the coins on the horizontal conveying surface 7 one by one along the conveying direction D.
　段差部６は、水平搬送面７から垂直に立設しており、搬送方向Ｄに沿って直線状に形成されている。段差部６の端面６１の上端と水平搬送面７との距離（段差部６の高さ）は、処理対象となる複数種類の硬貨の最小の厚さより小さい。リジェクト機構８は、段差部６の端面６１を跨ぐように段差部６の上面６２に対向配置される円柱状のローラ部材８１と、ローラ部材８１により移送された硬貨を排出するリジェクト穴８２とを有している。ローラ部材８１は、モータ等（不図示）の駆動力により回転しながら、ローラ部材８１の下端と段差部６の上面６２との間に硬貨を挟んでリジェクト穴８２に移送するように可撓性のある部材（例えばゴム）で形成されている。ローラ部材８１は、搬送方向Ｄに沿って等間隔に複数設けても良いし、搬送方向Ｄに沿うレバー部材３９の配置領域に亘って段差部６の上面６２と対向する単一部材で構成しても良い。 The step portion 6 stands upright from the horizontal transport surface 7 and is formed linearly along the transport direction D. The distance between the upper end of the end face 61 of the step portion 6 and the horizontal transport surface 7 (the height of the step portion 6) is smaller than the minimum thickness of a plurality of types of coins to be processed. The reject mechanism 8 includes a columnar roller member 81 disposed opposite the upper surface 62 of the step portion 6 so as to straddle the end surface 61 of the step portion 6, and a reject hole 82 for discharging coins transferred by the roller member 81. Have. The roller member 81 is rotated by a driving force of a motor or the like (not shown) and is flexible so that a coin is sandwiched between the lower end of the roller member 81 and the upper surface 62 of the step portion 6 and transferred to the reject hole 82. It is formed of a member (for example, rubber) having the following. A plurality of roller members 81 may be provided at equal intervals along the transport direction D, or may be configured as a single member facing the upper surface 62 of the step portion 6 over the arrangement region of the lever member 39 along the transport direction D. May be.
　上述したように、レバー部材３９の側面には、搬送中の硬貨を段差部６に向けて押付ける押付面３９ｃが形成されている。この押付面３９ｃは、搬送面となる摩擦部位３２ｃの表面から離間するに連れて段差部６に近付く方向に傾斜する傾斜部３９ｃ１を有している。この傾斜部３９ｃ１は、摩擦部位３２ｃの表面に対する垂線に対して所定の傾斜角θ（例えば、３０度）を有した同一平面上に形成されている。これにより、傾斜部３９ｃ１は、硬貨の厚み方向に対して水平搬送面７とは反対側である硬貨の周縁部上側に接触している。 As described above, on the side surface of the lever member 39, the pressing surface 39c for pressing the coin being conveyed toward the step portion 6 is formed. The pressing surface 39c has an inclined portion 39c1 that is inclined in a direction approaching the step portion 6 as the distance from the surface of the friction portion 32c serving as the conveying surface increases. The inclined portion 39c1 is formed on the same plane having a predetermined inclined angle θ (for example, 30 degrees) with respect to a perpendicular to the surface of the friction portion 32c. Thus, the inclined portion 39c1 is in contact with the upper side of the periphery of the coin, which is opposite to the horizontal transport surface 7 with respect to the coin thickness direction.
　レバー部材３９から変形硬貨Ｃ４に作用するレバー荷重Ｆの分力は、段差部６に向かう段差部押付力Ｆ１（＝Ｆｃｏｓ２θ）と、変形硬貨Ｃ４を水平搬送面７に押付ける搬送面押付力Ｆ２（＝Ｆｓｉｎθｃｏｓθ）とを含んでいる。段差部押付力Ｆ１は、変形硬貨Ｃ４を段差部６の端面６１と変形硬貨Ｃ４の周縁部とが摺接する摩擦力となり、静止状態の段差部６に対して、無端ベルト５のピン状部材５２の搬送力により変形硬貨Ｃ４が回転しながら搬送される（図１１参照）。そして、搬送面押付力Ｆ２が、段差部６の端面６１と変形硬貨Ｃ４の周縁部との間で発生する摩擦力のうち、変形硬貨Ｃ４を水平搬送面７に押付ける方向の摩擦力Ｆｍを上回ったとき、搬送中の変形硬貨Ｃ４の段差部６側の部位が浮き上がり、搬送中の変形硬貨Ｃ４の周縁部と段差部６の端面６１との当接が解除される（図１２参照）。 The component force of the lever load F acting on the deformed coin C4 from the lever member 39 includes a step pressing force F1 (= Fcos2θ) toward the step 6, and a transfer surface pressing force F2 pressing the deformed coin C4 against the horizontal transfer surface 7. (= F sin θ cos θ). The stepped portion pressing force F1 is a frictional force in which the end face 61 of the stepped portion 6 and the peripheral edge of the deformed coin C4 slide and contact the deformed coin C4, and the pin-shaped member 52 of the endless belt 5 with respect to the stepped portion 6 in a stationary state. The deformed coin C4 is conveyed while rotating due to the conveying force (see FIG. 11). The transfer surface pressing force F2 is the frictional force Fm in the direction of pressing the deformed coin C4 against the horizontal transfer surface 7 among the frictional force generated between the end surface 61 of the step portion 6 and the peripheral edge of the deformed coin C4. When it exceeds, the portion on the side of the stepped portion 6 of the deformed coin C4 being transported rises, and the contact between the peripheral edge portion of the deformed coin C4 being transported and the end face 61 of the stepped portion 6 is released (see FIG. 12).
　このとき、段差部６の高さ（段差部６における硬貨の周縁部に当接する部位の高さ）は、処理対象となる複数種類の硬貨の最小の厚さより小さいので、変形硬貨Ｃ４が段差部６を乗り越え、段差部押付力Ｆ１により押し出される（図１３参照）。押し出された変形硬貨Ｃ４は、ローラ部材８１の下端と段差部６の上面６２との間に挟まれてリジェクト穴８２に移送され、排出される。作用効果については上述した実施形態と同様であるので、説明を省略する。 At this time, the height of the stepped portion 6 (the height of the portion of the stepped portion 6 that contacts the periphery of the coin) is smaller than the minimum thickness of the plurality of types of coins to be processed. 6 and is pushed out by the step pressing force F1 (see FIG. 13). The extruded deformed coin C4 is transported to the reject hole 82 between the lower end of the roller member 81 and the upper surface 62 of the step portion 6, and is discharged. The operation and effect are the same as those of the above-described embodiment, and thus the description will be omitted.
（第３実施形態）
　第２実施形態では、無端ベルト５のピン状部材５２により硬貨を搬送方向Ｄに搬送すると共に、レバー部材３９により段差部６に搬送中の硬貨を押付けるように構成した。これに代えて本実施形態では、図１４に示すように、レバー部材３９の機能を無端ベルト５０（無端状回転体の一例）に兼用している。 (Third embodiment)
In the second embodiment, the coin is transported in the transport direction D by the pin-shaped member 52 of the endless belt 5, and the coin being transported is pressed against the step 6 by the lever member 39. Instead, in the present embodiment, as shown in FIG. 14, the function of the lever member 39 is shared by the endless belt 50 (an example of an endless rotating body).
　無端ベルト５０は、本体部５０ａと、本体部５０ａから突出して硬貨を押動する複数の板状部材５０ｂ（突出部の一例）とを有している。本体部５０ａは、不図示のプーリーに巻回される巻回部５０ａ１と、巻回部５０ａ１よりも大きい幅で巻回部５０ａ１と一体化され、板状部材５０ｂを固定する固定部５０ａ２とを有している。板状部材５０ｂは、水平搬送面７および搬送方向Ｄと垂直な平面に対して、側面視において搬送方向Ｄとは反対方向に第１所定角度θ１（例えば、３０度）傾いており、且つ平面視において搬送方向Ｄと同一方向に第２所定角度θ２（例えば、３０度）傾いている。 The endless belt 50 has a main body 50a and a plurality of plate members 50b (an example of a protruding portion) that protrude from the main body 50a and push coins. The main body 50a includes a winding part 50a1 wound around a pulley (not shown) and a fixing part 50a2 integrated with the winding part 50a1 with a width larger than the winding part 50a1 and fixing the plate-shaped member 50b. Have. The plate-shaped member 50b is inclined by a first predetermined angle θ1 (for example, 30 degrees) in a direction opposite to the transport direction D in a side view with respect to the horizontal transport surface 7 and a plane perpendicular to the transport direction D, and is flat. It is inclined by a second predetermined angle θ2 (for example, 30 degrees) in the same direction as the transport direction D when viewed.
　板状部材５０ｂから硬貨Ｃに作用する荷重Ｆの分力は、段差部６に向かう段差部押付力Ｆ１と、硬貨Ｃを水平搬送面７に押付ける搬送面押付力Ｆ２と、硬貨Ｃを搬送方向Ｄに沿って搬送する搬送力Ｆ３と、を含んでいる。つまり、硬貨Ｃに搬送力Ｆ３を付与する板状部材５０ｂは、搬送中の硬貨Ｃを段差部６に向けて押付ける押付部として構成されると共に、板状部材５０ｂの押付面は、硬貨Ｃの厚み方向に対して水平搬送面７とは反対側である硬貨Ｃの周縁部上側に接触する傾斜部５０ｂ１を有している。これにより、段差部押付力Ｆ１が硬貨Ｃを段差部６に対して押付ける摩擦力となるため、板状部材５０ｂの搬送力Ｆ３により硬貨Ｃが回転しながら搬送される。このとき、搬送面押付力Ｆ２により硬貨Ｃが水平搬送面７に押付けられているため、硬貨Ｃが変形硬貨である場合は、上述した実施形態と同様に段差部６を変形硬貨が乗り越え、排除される。 The component force of the load F acting on the coin C from the plate-shaped member 50b includes a step pressing force F1 toward the step 6, a transfer surface pressing force F2 pressing the coin C against the horizontal transfer surface 7, and a transfer of the coin C. And a transport force F3 for transporting along the direction D. That is, the plate-shaped member 50b that applies the transport force F3 to the coin C is configured as a pressing portion that presses the coin C being transported toward the step portion 6, and the pressing surface of the plate-shaped member 50b is the coin C. The coin C has an inclined portion 50b1 that is in contact with the upper side of the peripheral edge of the coin C, which is opposite to the horizontal transport surface 7 with respect to the thickness direction of the coin C. As a result, the step portion pressing force F1 becomes a frictional force for pressing the coin C against the step portion 6, so that the coin C is conveyed while rotating by the conveying force F3 of the plate member 50b. At this time, since the coin C is pressed against the horizontal transfer surface 7 by the transfer surface pressing force F2, when the coin C is a deformed coin, the deformed coin rides over the stepped portion 6 and is removed as in the above-described embodiment. Is done.
　本実施形態のように搬送中の硬貨Ｃを段差部６に向けて押付ける押付部が板状部材５０ｂに形成されていれば、上述したレバー部材３９の機構を設ける必要がないため、部品点数を節約して小型化を図りつつ装置コストを低減することができる。その他の作用効果については上述した実施形態と同様であるので、説明を省略する。 If the pressing portion for pressing the coin C being conveyed toward the step portion 6 is formed on the plate-like member 50b as in the present embodiment, it is not necessary to provide the mechanism of the lever member 39 described above. And the cost of the apparatus can be reduced while reducing the size. Other functions and effects are the same as those of the above-described embodiment, and thus description thereof will be omitted.
（他の実施形態）
（１）第１実施形態や第２実施形態にかかる押付面３９ｃの傾斜部３９ｃ１は、複数の傾斜角を持って構成しても良い。例えば、傾斜部３９ｃ１の所定の傾斜角θとして、上端から中間までの範囲を３０度で構成し、中間から下端までの範囲を２０度で構成しても良い。この場合、変形硬貨が搬送面に近付いたとき、傾斜角の小さい傾斜部３９ｃ１に当接することとなり、段差部押付力Ｆ１が増大するので、変形硬貨の押出力を高めることができる。しかも、変形度合いの大きい変形硬貨は、搬送面から離間した部位が傾斜部３９ｃ１の上端付近に当接することとなり、搬送面押付力Ｆ２が増大するので、該離間した部位が搬送面に近接移動し易くなり、変形硬貨を速やかに排除することができる。同様に、第３実施形態にかかる板状部材５０ｂの傾斜部５０ｂ１の第１所定角度θ１を複数の角度で構成しても良い。 (Other embodiments)

For example, as the predetermined inclination angle θ of the inclined portion 39c1, the range from the upper end to the middle may be configured as 30 degrees, and the range from the middle to the lower end may be configured as 20 degrees. In this case, when the deformed coin approaches the transport surface, the deformed coin comes into contact with the inclined portion 39c1 having a small inclination angle, and the step portion pressing force F1 increases, so that the pushing force of the deformed coin can be increased. Moreover, in the deformed coin having a large degree of deformation, the portion separated from the transport surface comes into contact with the vicinity of the upper end of the inclined portion 39c1, and the transport surface pressing force F2 increases, so that the separated portion moves closer to the transport surface. This makes it easy to remove deformed coins quickly. Similarly, the first predetermined angle θ1 of the inclined portion 50b1 of the plate-like member 50b according to the third embodiment may be constituted by a plurality of angles.
（２）第１実施形態や第２実施形態にかかる押付面３９ｃの傾斜部３９ｃ１は、押付面３９ｃの一部に形成しても良い。例えば、傾斜部３９ｃ１の所定の傾斜角θとして、上端から最小硬貨の厚さ以下までの範囲を３０度で構成し、最小硬貨の厚さ以下から下端までの範囲を搬送面と垂直な平面で構成しても良い。この場合でも、硬貨が搬送面に押付けられるまで、硬貨に搬送面押付力Ｆ２を作用させることができる。 (2) The inclined portion 39c1 of the pressing surface 39c according to the first embodiment or the second embodiment may be formed on a part of the pressing surface 39c. For example, as the predetermined inclination angle θ of the inclined portion 39c1, the range from the upper end to the thickness of the minimum coin is equal to or less than 30 degrees, and the range from the thickness of the minimum coin to the lower end is defined by a plane perpendicular to the transport surface. You may comprise. Even in this case, the transfer surface pressing force F2 can be applied to the coin until the coin is pressed against the transfer surface.
（３）変形硬貨を排除する機構は、硬貨繰出装置３０に設けずに、入金搬送部２０のうち識別部２２よりも上流側に設けても良いし、単に変形硬貨を排除する装置として単独で構成しても良い。 (3) The mechanism for removing deformed coins may be provided on the upstream side of the discriminating section 22 of the deposit transport section 20 without being provided in the coin feeding device 30, or may be used alone as a device for simply removing deformed coins. You may comprise.
（４）第１実施形態では、回転円盤３２を、上下方向に対して傾斜した姿勢にて配置された。これに代えて、回転円盤３２の盤面を地面と平行である水平面に配置することも可能である。この場合、第２実施形態のようなリジェクト機構８を設けることが好ましい。
（５）第２実施形態や第３実施形態において、水平搬送面７を傾斜させても良い。この場合、リジェクト機構８を省略することができる。
（６）第２実施形態や第３実施形態における段差部６において、第１実施形態にかかる段差部３２ｄのように傾斜部位３２ｆを設けても良い。 (4) In the first embodiment, the rotating disk 32 is arranged in a posture inclined with respect to the vertical direction. Alternatively, the surface of the rotating disk 32 can be arranged on a horizontal plane parallel to the ground. In this case, it is preferable to provide a reject mechanism 8 as in the second embodiment.
(5) In the second and third embodiments, the horizontal transport surface 7 may be inclined. In this case, the reject mechanism 8 can be omitted.
(6) In the step portion 6 in the second embodiment or the third embodiment, an inclined portion 32f may be provided like the step portion 32d according to the first embodiment.
（７）硬貨処理装置は、上述した硬貨入金機１０の他、様々な装置として適用可能である。例えば、ＡＴＭ、つり銭機などの硬貨を処理する装置や、遊技機等に用いられるメダルを処理する装置（メダル計数機等）に適用可能である。 (7) The coin processing device is applicable as various devices other than the coin depositing machine 10 described above. For example, the present invention is applicable to an apparatus for processing coins such as ATMs and change machines, and an apparatus for processing medals (medal counters and the like) used in gaming machines and the like.
