　本開示は、回転部材に噛み合った状態で搬送対象物を搬送面に押圧しながら周方向に沿って搬送する搬送無端ベルトおよび搬送無端ベルトを備えた硬貨処理装置に関する。 The present disclosure relates to a coin processing device including a conveyance endless belt and a conveyance endless belt that convey a conveyance target along a circumferential direction while pressing an object to be conveyed against a conveyance surface in a state of being engaged with a rotating member.
　硬貨入金機やＡＴＭ等に内蔵される硬貨処理装置は、プーリー（回転部材）に噛み合った状態で硬貨（搬送対象物）を搬送面に押圧しながら周方向に沿って搬送する搬送無端ベルトを備えている。 A coin processing device incorporated in a coin depositing machine or an ATM has a conveying endless belt which conveys a coin (conveying object) along a circumferential direction while pressing a coin (conveying object) in a state of being engaged with a pulley (rotating member) ing.

　ところで、硬貨は複数種類のものが存在し、特に外国の硬貨においては、少なくとも厚さが２倍以上異なる複数種類の硬貨が存在している。 By the way, there are a plurality of types of coins, and in particular, in foreign coins, there are a plurality of types of coins different in thickness by at least twice.
　特許文献１に記載の丸ベルトにおいては、厚さが最も大きい硬貨が押圧された状態のとき、全体的にベルトが撓んで該硬貨の周辺には大きな空間が作り出される。このとき、隣り合う厚さが最も小さい硬貨が存在すると、大きな空間が形成されることにより丸ベルトで硬貨を押圧することができず、硬貨を搬送することができないおそれがある。 In the round belt described in Patent Document 1, when the coin with the largest thickness is pressed, the belt generally bends to create a large space around the coin. At this time, if adjacent coins having the smallest thickness are present, a large space is formed, so that the coin can not be pressed by the round belt, and there is a possibility that the coin can not be transported.
　特許文献２に記載のピン付きベルトにおいては、硬貨を押圧して搬送する形態ではなく、硬貨を係止板で係止して搬送する形態であるため、硬貨の搬送姿勢が安定しない。その結果、硬貨の識別や振分け選別が正確に行えないという問題があった。 In the belt with pin described in Patent Document 2, the coin transport posture is not stable because the coin is not transported by pressing it but transported by being locked by the locking plate. As a result, there has been a problem that coin identification and sorting can not be accurately performed.
　そこで、厚さの異なる搬送対象物であっても確実に搬送できる搬送無端ベルトおよび該搬送無端ベルトを有する硬貨処理装置が望まれている。 Therefore, a transport endless belt capable of reliably transporting even objects to be transported having different thicknesses and a coin processing device having the transport endless belt are desired.
　本開示の一態様における搬送無端ベルトの特徴構成は、回転部材に噛み合った状態で搬送対象物を搬送面に押圧しながら搬送方向となる周方向に沿って搬送する搬送無端ベルトであって、前記回転部材に支持される本体部と、前記本体部から幅方向に延出した弾性変形部と、を備え、前記弾性変形部は、前記本体部よりも弾性率が小さく構成されており、前記弾性変形部の端部と前記搬送対象物とが接触したとき、前記端部が前記幅方向および前記周方向と垂直な方向である径方向に変形して、前記搬送対象物が前記端部により押圧保持される点にある。 A characterizing feature of the transport endless belt according to one aspect of the present disclosure is a transport endless belt that transports a transport target along a circumferential direction which is a transport direction while pressing a transport object against a transport surface in a state of meshing with a rotating member, A main body supported by a rotating member, and an elastic deformation portion extending in the width direction from the main body, the elastic deformation portion having a smaller elastic modulus than the main body, the elastic When the end of the deformation portion contacts the object to be conveyed, the end deforms in the radial direction which is the direction perpendicular to the width direction and the circumferential direction, and the object to be conveyed is pressed by the end It is in the point to be held.
　本構成では、搬送無端ベルトを本体部と本体部から幅方向に延出した弾性変形部とで形成し、この弾性変形部は本体部よりも弾性率（変形のしにくさを表す物性値）が小さく構成されている。つまり、弾性変形部は、本体部よりも径方向に弾性変形し易く構成されている。これにより、本体部は回転部材に支持された状態で変形し難く、搬送無端ベルトが搬送対象物に接触したときには弾性変形部が径方向に変形して、弾性変形部の端部で搬送対象物を押圧保持する。 In this configuration, the transport endless belt is formed of the main body portion and an elastic deformation portion extending in the width direction from the main body portion, and the elastic deformation portion has an elastic modulus (a physical property value indicating difficulty in deformation) than the main body portion. Is made smaller. That is, the elastically deformable portion is configured to be more easily elastically deformed in the radial direction than the main body portion. Thereby, the main body portion is hardly deformed in a state supported by the rotating member, and when the transport endless belt contacts the transport target, the elastic deformation portion is deformed in the radial direction, and the transport target object at the end of the elastic deformation portion Press and hold.
　その結果、弾性変形部の端部の押圧保持によって搬送対象物の搬送姿勢が安定するので、搬送対象物の検査（硬貨の場合の識別）や振分け選別といった所定の処理を正確に行うことができる。しかも、弾性率の小さい弾性変形部の端部を径方向に変形させることにより該端部で搬送対象物を保持するので、全体的にベルトが撓むことなく、該端部に保持された搬送対象物と隣接する部位には、弾性変形部の変形により生じる空間を最小限とすることが可能となる。よって、隣り合う搬送対象物の厚さが異なる場合であっても、搬送対象物を弾性変形部の端部によって確実に保持することができる。 As a result, since the conveyance posture of the object to be conveyed is stabilized by pressing and holding the end of the elastic deformation portion, predetermined processing such as inspection of the object to be conveyed (identification in the case of coins) and sorting and sorting can be accurately performed. . In addition, since the object to be conveyed is held at the end by deforming the end of the elastic deformation portion having a small elastic modulus in the radial direction, the conveyance is held at the end without the belt being bent as a whole. In the portion adjacent to the object, it is possible to minimize the space generated by the deformation of the elastic deformation portion. Therefore, even when the thicknesses of the adjacent objects to be transferred are different, the objects to be transferred can be reliably held by the end portions of the elastically deformable portions.
　このように、厚さの異なる搬送対象物であっても確実に搬送できる搬送無端ベルトを提供できた。 Thus, it was possible to provide a transport endless belt capable of reliably transporting even a transport target having different thickness.
　他の特徴構成は、前記本体部と前記弾性変形部とは同一材料で構成されており、前記弾性変形部の前記径方向の厚さが前記本体部の前記径方向の厚さよりも小さく形成されている点にある。 Another characteristic configuration is that the main body portion and the elastic deformation portion are made of the same material, and the radial thickness of the elastic deformation portion is formed smaller than the radial thickness of the main body portion The point is.
　本構成のように、本体部および弾性変形部における径方向の厚さを異ならせるだけで、弾性変形部における弾性率を本体部における弾性率よりも小さく構成することが可能となるので、製造効率を高めることができる。 As in the present configuration, it is possible to configure the elastic modulus in the elastically deformable portion to be smaller than the elastic modulus in the main body simply by making the thickness in the radial direction different between the main body and the elastically deformable portion. Can be enhanced.
　他の特徴構成は、前記本体部には、前記周方向に伸縮しない芯体が埋設されている点にある。 Another characteristic configuration is that a core not embedded in the circumferential direction is embedded in the main body.
　本構成のように本体部に周方向に伸縮しない芯体を埋設すれば、弾性変形部の捻れに連動して本体部が捻れるといったことが無い。その結果、搬送対象物を押圧する弾性変形部の変形により生じる空間が、本体部の捻れによって拡大されるといった不都合を防止できる。 By embedding a core that does not expand and contract in the circumferential direction in the main body as in this configuration, the main body does not twist in conjunction with the twisting of the elastically deformable portion. As a result, it is possible to prevent such a disadvantage that the space generated by the deformation of the elastically deformable portion pressing the object to be conveyed is enlarged by the twisting of the main body portion.
　他の特徴構成は、前記弾性変形部は、前記周方向に沿って互いに離間した複数の棒状部位を有しており、複数の前記棒状部位は、前記周方向に伸縮可能な伸縮体により互いに結合されている点にある。 Another characteristic configuration is that the elastically deformable portion has a plurality of rod-like portions separated from each other along the circumferential direction, and the plurality of rod-like portions are coupled to each other by the stretchable body that is stretchable in the circumferential direction. It is in the point being done.
　本構成では、弾性変形部が複数の棒状部位を有しているので、仮に搬送対象物が周方向に滑り移動したとしても、棒状部位のエッジによって該移動を阻止することができる。しかも、本構成では、これら棒状部位を周方向に伸縮可能な伸縮体により互いに結合しているので、弾性変形部が捻れ変形した場合でも、伸縮体が捻れ変形に追従する。つまり、互いに離間した棒状部位が捻れ変形に追従する伸縮体によって結合されているので、棒状部位の根元部位が捻れ変形することによって亀裂が発生するといった不都合を防止することができる。 In this configuration, since the elastically deformable portion has a plurality of rod-like portions, even if the object to be conveyed slides in the circumferential direction, the movement of the object can be blocked by the edges of the rod-like portions. Moreover, in the present configuration, since the bar-like portions are connected to each other by the stretchable body that can stretch in the circumferential direction, the stretchable body follows the twisting deformation even when the elastically deformable portion is twisted and deformed. That is, since the bar-like portions separated from each other are connected by the stretchable body that follows the torsional deformation, it is possible to prevent the problem that the crack is generated due to the torsional deformation of the root portion of the bar-like portion.
　他の特徴構成は、前記搬送対象物は、少なくとも厚さの異なる複数種類の硬貨である点にある。 Another feature is that the object to be transported is at least a plurality of types of coins having different thicknesses.
　本構成のように搬送対象物を厚さの異なる複数種類の硬貨の場合には、搬送無端ベルトを厚さが大きく異なる複数種類の硬貨にも対応させることができる。よって、本構成の搬送無端ベルトを厚さが２倍以上異なる外国硬貨の処理にも使用することができ、硬貨処理装置のグローバル化も可能となる。 In the case of a plurality of types of coins having different thicknesses as in this configuration, the transport endless belt can be made to correspond to a plurality of types of coins having significantly different thicknesses. Therefore, the transport endless belt of this configuration can be used for processing foreign coins different in thickness by a factor of 2 or more, and the coin processing device can be globalized.
　本開示の一態様における硬貨処理装置の特徴構成は、回転する硬貨搬送円盤と、前記搬送無端ベルトと、を備え、前記硬貨搬送円盤は、上面に接触した硬貨を前記搬送無端ベルトに向けて搬送し、前記弾性変形部の前記端部は、前記硬貨搬送円盤の前記上面にある前記硬貨に接触して前記径方向に弾性変形した状態で前記硬貨を押圧保持し、前記硬貨を前記硬貨搬送円盤の外部へ搬送する点にある。 A characteristic configuration of the coin processing device according to one aspect of the present disclosure includes a rotating coin transport disk and the transport endless belt, and the coin transport disk transports a coin in contact with the upper surface toward the transport endless belt. And the end portion of the elastically deforming portion presses and holds the coin in a state of being elastically deformed in the radial direction by being in contact with the coin on the upper surface of the coin transfer disc, and the coin is transferred to the coin transfer disc Transport to the outside of the
　本構成では、硬貨搬送円盤によって硬貨が搬送無端ベルトまで搬送され、弾性変形部の端部に接触した硬貨は搬送無端ベルトの端部に押圧保持されながら硬貨搬送円盤の外部に移動する。このとき、上述したように弾性率の小さい弾性変形部の端部を径方向に変形させることにより該端部で搬送対象物を保持するので、全体的にベルトが撓むことなく、該端部に保持された搬送対象物と隣接する部位には、弾性変形部の変形により生じる空間を最小限とすることが可能となる。よって、硬貨搬送円盤から複数の硬貨が連なって移動してきた場合でも、これらの硬貨を硬貨搬送円盤の外部へと円滑に搬送することができる。 In this configuration, the coin is transported to the transport endless belt by the coin transport disk, and the coin in contact with the end of the elastic deformation portion moves to the outside of the coin transport disk while being pressed and held by the end of the transport endless belt. At this time, as described above, the end portion of the elastic deformation portion having a small elastic modulus is deformed in the radial direction to hold the object to be conveyed by the end portion. It is possible to minimize the space generated by the deformation of the elastically deformable portion in the portion adjacent to the object to be transported held by the. Therefore, even when a plurality of coins move in a row from the coin transport disk, these coins can be smoothly transported to the outside of the coin transport disk.
　本開示の一態様における硬貨処理装置の特徴構成は、硬貨を搬送する搬送通路と、前記搬送無端ベルトと、前記搬送無端ベルトを前記搬送通路に沿って配置するベルト駆動機構と、を備え、前記ベルト駆動機構は、前記弾性変形部の前記端部を前記搬送通路の搬送面に対して前記幅方向に所定間隔を空けて配置し、前記弾性変形部の弾性復元作用により、前記搬送通路の一方側に形成された基準面に硬貨を寄せつつ搬送する点にある。 A characteristic configuration of a coin processing device according to one aspect of the present disclosure includes a conveyance passage for conveying a coin, the conveyance endless belt, and a belt drive mechanism for arranging the conveyance endless belt along the conveyance passage. The belt drive mechanism arranges the end portion of the elastically deformable portion at a predetermined interval in the width direction with respect to the transport surface of the transport passage, and one of the transport passages is resiliently restored by the elastically deformable portion. The point is that the coin is transported while being brought close to the reference surface formed on the side.
　本構成では、弾性変形部の端部と搬送通路の搬送面との間に形成された所定間隔に硬貨が進入し、搬送無端ベルトの端部によって該硬貨が押圧保持される。このとき、径方向に弾性変形する弾性変形部の弾性復元作用により、搬送通路の一方側に形成された基準面に硬貨を寄せつつ搬送するので、硬貨を基準面に確実に寄せた状態で搬送することができる。 In this configuration, the coin enters at a predetermined interval formed between the end of the elastic deformation portion and the conveyance surface of the conveyance passage, and the coin is pressed and held by the end of the conveyance endless belt. At this time, since the coins are conveyed while being brought close to the reference surface formed on one side of the conveyance passage by the elastic restoring action of the elastically deformable portion elastically deformed in the radial direction, the conveyance is carried in a state where the coins are surely brought close to the reference surface can do.

　ベルト３３は、ゴム等の弾性部材で構成されており、後述する第１プーリー３４ａ（回転部材の一例）および第２プーリー３４ｅ（回転部材の一例）に噛み合った状態で硬貨を搬送面（後述する硬貨搬送円盤３２の摩擦搬送部位３２ｃの上面、後述する入金搬送部２０の搬送路側面２１ｃ）に押圧しながら搬送方向に沿って搬送する。ベルト駆動機構３４は、ベルト３３を搬送通路（後述する摩擦搬送部位３２ｃ、後述する入金搬送部２０の搬送路２１ａ）に沿って配置して移動させる。 The belt 33 is made of an elastic member such as rubber, and the coin transport surface (described later) in a state of being engaged with a first pulley 34a (an example of a rotating member) and a second pulley 34e (an example of a rotating member) While pressing on the upper surface of the friction transfer portion 32 c of the coin transfer disk 32 and the transfer path side surface 21 c of the deposit transfer unit 20 described later, the transfer is performed along the transfer direction. The belt drive mechanism 34 arranges and moves the belt 33 along a conveyance passage (a friction conveyance portion 32 c described later, a conveyance passage 21 a of the deposit conveyance unit 20 described later).
　カバー部材３５は、硬貨搬送円盤３２の下部領域を覆う樹脂製の部材であって、硬貨搬送円盤３２との間に硬貨貯留空間３６を形成する。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、硬貨搬送円盤３２とカバー部材３５との間に形成される空間である（図２，図７～図９参照）。 The cover member 35 is a member made of resin that covers the lower region of the coin transport disk 32, and forms a coin storage space 36 with the coin transport disk 32.

　このような硬貨繰出装置３０の構成の詳細について図３～図１１を用いて説明する。 The details of the configuration of such a coin feeding device 30 will be described with reference to FIGS. 3 to 11.
（硬貨搬送円盤）
　硬貨搬送円盤３２は上述の通り、上下方向に対して傾斜した姿勢にて、回転軸３２ａを回転軸として回転する円盤であって、硬貨貯留空間３６に貯留された硬貨を硬貨搬送円盤３２の下部領域から上部領域へ、すなわちベルト３３へ向けて搬送する。硬貨搬送円盤３２は、図３、図６等に示すように、摩擦搬送部位３２ｃおよび段差部位３２ｄを有して構成される。硬貨搬送円盤３２は、摩擦搬送部位３２ｃの上面（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る。このとき回転軸３２ａは、ベース部材３１と垂直である。 (Coin transport disc)
As described above, the coin transport disk 32 is a disk that rotates around the rotary shaft 32 a as a rotational shaft in a posture inclined with respect to the vertical direction, and the coin stored in the coin storage space 36 is a lower portion of the coin transport disk 32 Conveying from the area to the upper area, ie towards the belt 33. As shown in FIG. 3, FIG. 6, etc., the coin transport disk 32 is configured to have a friction transport portion 32 c and a step portion 32 d. The coin transport disk 32 is disposed such that the upper surface (an example of the transport surface) of the friction transfer portion 32 c is parallel to the upper surface of the base member 31. At this time, the rotation shaft 32 a is perpendicular to the base member 31.
　硬貨搬送円盤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、異物が硬貨搬送円盤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。硬貨搬送円盤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。 With regard to the inclination angle (angle with respect to the ground) of the coin transport disk 32, the larger the inclination angle, the harder it is for foreign matter to reach the upper region of the coin transport disk 32 and the foreign substance removal capability improves, but coin transport also becomes difficult. . 35 degrees or more are preferable and, as for the inclination angle of the coin conveyance disc 32, 35 degrees or more and 40 degrees or less are suitable.
　摩擦搬送部位３２ｃは、硬貨搬送円盤３２の上面に形成された環状の部位である。摩擦搬送部位３２ｃの幅は、硬貨入金機１０の搬送対象物となる複数種類の硬貨の最大直径よりも大きい。摩擦搬送部位３２ｃは、硬貨との摩擦が大きくなるよう形成された部位であって、具体的には、硬貨搬送円盤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。摩擦搬送部位３２ｃは、当該摩擦搬送部位３２ｃに接触した硬貨を、当該硬貨との摩擦力により硬貨搬送円盤３２の上部領域に搬送する。 The friction transfer portion 32 c is an annular portion formed on the top surface of the coin transfer disk 32. The width of the friction transfer portion 32 c is larger than the maximum diameter of the plurality of types of coins to be transferred by the coin depositing machine 10. The friction transfer portion 32c is a portion formed to increase friction with the coin, and specifically, rubber, resin, or the like is attached to the surface of the coin transfer disk 32. The friction conveyance part 32c conveys the coin in contact with the friction conveyance part 32c to the upper region of the coin conveyance disc 32 by the friction with the coin.
　段差部位３２ｄは、硬貨搬送円盤３２の上面において、摩擦搬送部位３２ｃの径方向内側に形成され、摩擦搬送部位３２ｃに対して上側に突出した部位である。本実施形態の段差部位３２ｄは、円盤状の薄板部材を、その中心軸を硬貨搬送円盤３２の回転軸３２ａと一致させた状態で硬貨搬送円盤３２の上面に取り付けて形成されている。段差部位３２ｄの外周面３２ｅ（基準面の一例）と、硬貨搬送円盤３２の外周３２ｂとは、いずれも硬貨搬送円盤３２の回転軸３２ａを中心とする円形状である。 The stepped portion 32d is a portion that is formed on the upper surface of the coin conveyance disk 32 radially inward of the friction conveyance portion 32c and protrudes upward with respect to the friction conveyance portion 32c. The stepped portion 32 d of the present embodiment is formed by attaching a disk-like thin plate member to the upper surface of the coin transport disk 32 in a state where the central axis thereof coincides with the rotation shaft 32 a of the coin transport disk 32. The outer peripheral surface 32e (an example of the reference surface) of the stepped portion 32d and the outer periphery 32b of the coin transport disk 32 are both circular around the rotation shaft 32a of the coin transport disk 32.
　段差部位３２ｄの上面は、摩擦搬送部位３２ｃの上面よりも上側に位置している。本実施形態では、段差部位３２ｄの外周近傍に傾斜部位３２ｆが形成されており（図６～図７参照）、段差部位３２ｄの周囲はテーパ状となっている。段差部位３２ｄの外周面３２ｅの上端と、摩擦搬送部位３２ｃの上面との距離は、搬送対象物であ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、硬貨搬送円盤３２の上で重なって搬送され、段差部位３２ｄに接触した場合には、下側の硬貨すなわち硬貨搬送円盤３２（摩擦搬送部位３２ｃの上面）に接触している硬貨のみが段差部位３２ｄに当接し、他方の硬貨（硬貨の上に重なっている硬貨）は、段差部位３２ｄに接触し得ない。これにより、重送硬貨の捌きを適切に行うことが可能となる。 The upper surface of the stepped portion 32d is located above the upper surface of the friction transfer portion 32c. In the present embodiment, the inclined portion 32f is formed in the vicinity of the outer periphery of the stepped portion 32d (see FIGS. 6 to 7), and the periphery of the stepped portion 32d is tapered. The distance between the upper end of the outer peripheral surface 32e of the stepped portion 32d and the upper surface of the friction transfer portion 32c is smaller than the minimum thickness of the plurality of types of coins to be transferred. Then, two coins having the smallest thickness among a plurality of types of coins are overlapped and transported on the coin transport disk 32, and when they come in contact with the step portion 32d, the lower coin, that is, the coin transport disk 32 ( Only the coin in contact with the upper surface of the friction transfer portion 32c abuts on the step portion 32d, and the other coin (coin overlapping on the coin) can not contact the step portion 32d. Thereby, it is possible to appropriately perform the double feeding of coins.
（入金搬送部）
　入金搬送部２０は、左右方向に沿って延びる上部搬送部分２０ａと、上部搬送部分２０ａから送られた硬貨を搬送し、この際に硬貨の搬送方向を逆方向に変える折り返し搬送部分２０ｂと、上部搬送部分２０ａの下方に設けられると共に左右方向に沿って延び、折り返し搬送部分２０ｂから送られた硬貨を搬送する下部搬送部分２０ｃとを有している。そして、硬貨搬送円盤３２から繰り出された硬貨は上部搬送部分２０ａ、折り返し搬送部分２０ｂ、下部搬送部分２０ｃの順に搬送されるようになっている。また、上部搬送部分２０ａおよび下部搬送部分２０ｃには、識別部２２による硬貨の識別結果に基づいて硬貨の選別を行う選別部２４（２４ａ～２４ｈ）がそれぞれ複数設けられている（図１および図３参照）。 (Payment Transfer Unit)
The deposit transport unit 20 transports the upper transport portion 20a extending along the left-right direction, the folded transport portion 20b that transports the coin sent from the upper transport portion 20a, and reverses the coin transport direction at this time, and the top The lower conveying portion 20c is provided below the conveying portion 20a and extends in the left-right direction, and conveys the coin sent from the folded conveying portion 20b. And the coin drawn out from the coin conveyance disk 32 is conveyed in order of the upper conveyance part 20a, the return conveyance part 20b, and the lower conveyance part 20c. In addition, a plurality of sorting units 24 (24a to 24h) for sorting coins based on the identification results of the coins by the identification unit 22 are respectively provided in the upper transport portion 20a and the lower transport portion 20c (FIG. 1 and FIG. 3).
　上部搬送部分２０ａは、左右方向に沿って延びる搬送路２１ａ（搬送通路の一例）と、この搬送路２１ａに沿って設けられたベルト３３とから構成されており、搬送路２１ａに沿ってベルト３３により硬貨が１枚ずつ搬送されるようになっている。より詳細には、搬送路２１ａは搬送路側面２１ｃ（搬送面の一例）および搬送路底面２１ｄ（基準面の一例）から構成されており、搬送路側面２１ｃは上下方向に対して所定の角度で傾斜した傾斜面となっている。そして、図３に示すように、搬送路２１ａにおいて、硬貨は自重により搬送路底面２１ｄに接触するよう、ベルト３３により搬送路側面２１ｃに沿って図３における右方向に搬送されるようになっている。また、硬貨は、後述するベルト３３の弾性変形部３３ｂの弾性復元作用により硬貨が搬送路側面２１ｃおよび搬送路底面２１ｄの両方に押圧された状態で搬送される（図６参照）。 The upper conveyance portion 20a is constituted by a conveyance path 21a (an example of a conveyance path) extending along the left-right direction and a belt 33 provided along the conveyance path 21a, and the belt 33 along the conveyance path 21a. Coins are transported one by one. More specifically, the transport path 21a is composed of a transport path side surface 21c (an example of a transport surface) and a transport path bottom surface 21d (an example of a reference surface), and the transport path side surface 21c is at a predetermined angle with respect to the vertical direction. It is an inclined slope. Then, as shown in FIG. 3, in the transport path 21a, the coin is transported by the belt 33 in the right direction in FIG. 3 along the transport path side surface 21c so as to contact the transport path bottom surface 21d by its own weight. There is. The coin is transported in a state where the coin is pressed against both the transport path side surface 21c and the transport path bottom surface 21d by the elastic restoring action of the elastic deformation portion 33b of the belt 33 described later (see FIG. 6).
　ベルト３３は、摩擦搬送部位３２ｃの上面又は搬送路側面２１ｃと当該ベルト３３の弾性変形部３３ｂの端部３３ｂ１との間で硬貨を押圧保持しながら当該硬貨を搬送するようになっている。また、上部搬送部分２０ａには複数（具体的には５つ）の選別部２４（２４ａ～２４ｅ）が設けられている。また、図３に示すように、上部搬送部分２０ａにおける各選別部２４の上流側には識別部２２が設けられており、この識別部２２は、硬貨繰出装置３０から繰り出された硬貨の金種や真偽等の識別を行うようになっている。 The belt 33 transports the coin while pressing and holding the coin between the upper surface or the transport path side surface 21c of the friction transport portion 32c and the end 33b1 of the elastic deformation portion 33b of the belt 33. Further, a plurality of (specifically, five) sorting units 24 (24a to 24e) are provided in the upper transport portion 20a. Further, as shown in FIG. 3, an identification unit 22 is provided on the upstream side of each sorting unit 24 in the upper conveyance portion 20 a, and this identification unit 22 is a denomination of coins drawn out from the coin feeding device 30. It is designed to identify the truth or falsehood.
　上部搬送部分２０ａに設けられた各選別部２４は、識別部２２による硬貨の識別結果に基づいて、この上部搬送部分２０ａにより搬送される硬貨を選別してリジェクト部４７やオーバーフローボックス４９、又は一時保留部４０に送るようになっている（図１～図２参照）。具体的には、上部搬送部分２０ａに設けられた合計５つの選別部２４のうち、硬貨の搬送方向における最も上流側にある選別部２４ａは、リジェクト硬貨（真正でない硬貨）の選別を行うリジェクト選別部として機能するようになっており、この選別部２４ａによりリジェクト硬貨が選別されてリジェクト部４７に送られるようになっている。また、上部搬送部分２０ａに設けられた合計５つの選別部２４のうち、硬貨の搬送方向において上流側から３番目に配置された選別部２４ｃは、一時保留部４０の下流に位置する収納繰出装置（不図示）が既に満杯であるようなオーバーフロー硬貨の選別を行うオーバーフロー選別部として機能するようになっており、この選別部２４ｃによりオーバーフロー硬貨が選別されてオーバーフローボックス４９に送られるようになっている。 Each sorting unit 24 provided in the upper transport portion 20a sorts the coins transported by the upper transport portion 20a based on the identification result of the coin by the identification unit 22 and rejects the reject portion 47, the overflow box 49, or the temporary It is sent to the holding unit 40 (see FIGS. 1 and 2). Specifically, among the total of five sorting units 24 provided in the upper transport portion 20a, the sorting unit 24a located on the most upstream side in the coin transport direction is a reject sorting in which reject coins (coincidence coins) are sorted The reject coin is sorted by the sorting unit 24 a and sent to the reject unit 47. Further, among the total of five sorting units 24 provided in the upper conveyance portion 20a, the sorting unit 24c disposed third from the upstream side in the coin conveyance direction is a storage and feeding device positioned downstream of the temporary storage unit 40. (Not shown) functions as an overflow sorting unit for sorting overflow coins that are already full, and the sorting unit 24 c sorts the overflow coins and sends them to the overflow box 49. There is.
　また、上部搬送部分２０ａに設けられた合計５つの選別部２４のうち、上述した選別部２４ａ、２４ｃ以外の選別部２４ｂ、２４ｄ、２４ｅは、金種別に硬貨を選別する金種別選別部として機能するようになっている。より具体的には、例えば本実施形態の硬貨入金機１０においてユーロ（ＥＵＲＯ）硬貨の処理が行われるときに、硬貨の搬送方向において上流側から２番目に配置された選別部２４ｂは、識別部２２により１セント硬貨であると識別された硬貨を選別し、硬貨の搬送方向において上流側から４番目に配置された選別部２４ｄは、識別部２２により５セント硬貨であると識別された硬貨を選別し、硬貨の搬送方向において上流側から５番目に配置された選別部２４ｅは、識別部２２により１０セント硬貨であると識別された硬貨を選別するようになっている。 Further, among the total of five sorting units 24 provided in the upper conveyance portion 20a, the sorting units 24b, 24d and 24e other than the above-described sorting units 24a and 24c function as denomination sorting units that sort coins according to denominations. It is supposed to More specifically, for example, when processing of a Euro (EURO) coin is performed in the coin depositing machine 10 of the present embodiment, the sorting unit 24b secondly arranged from the upstream side in the coin conveyance direction is an identification unit The sorting unit 24d, which sorts out the coins identified as being 1 cent coins by 22 and is arranged fourth from the upstream side in the coin transport direction, selects the coins identified as being 5 cent coins by the identification unit 22. The sorting unit 24e that is sorted and arranged fifth from the upstream side in the coin transport direction is configured to sort coins identified as being 10-cent coins by the identification unit 22.
　各選別部２４の構成の詳細について図３を用いて説明する。図３に示すように、上部搬送部分２０ａにおける搬送路２１ａの搬送路側面２１ｃには、各選別部２４にそれぞれ対応して開口２５が設けられている。各開口２５にはシュート２６（図１および図２参照）が接続されている。ベルト３３により搬送路２１ａに沿って搬送される硬貨が開口２５に入ったときに、この硬貨は対応するシュート２６に送られて、最終的にはシュート２６を介して自重によりリジェクト部４７やオーバーフローボックス４９、又は一時保留部４０に硬貨が送られるようになる。 The details of the configuration of each sorting unit 24 will be described with reference to FIG. As shown in FIG. 3, an opening 25 is provided corresponding to each sorting unit 24 on the side surface 21 c of the transport path 21 a in the upper transport portion 20 a. A chute 26 (see FIGS. 1 and 2) is connected to each opening 25. When a coin transported along the transport path 21a by the belt 33 enters the opening 25, the coin is sent to the corresponding chute 26 and finally, due to its own weight via the chute 26, the reject portion 47 or the overflow The coin is sent to the box 49 or the temporary storage unit 40.
　また、各開口２５の下方には分岐部材２７がそれぞれ設けられている。各分岐部材２７は、通常時には搬送路２１ａにおける搬送路底面２１ｄの下方に位置しており、硬貨の選別を行う際には搬送路底面２１ｄの上方に進出するようになっている。より詳細には、分岐部材２７が搬送路２１ａの搬送路底面２１ｄの下方に位置しており、分岐部材２７の最も高い位置がこの搬送路底面２１ｄと同じ高さに位置しているときには、搬送路２１ａで搬送される硬貨は分岐部材２７により搬送路底面２１ｄから上方に押し上げられることはない。このため、搬送路２１ａで搬送される硬貨は開口２５に入ることはない。一方、分岐部材２７が搬送路２１ａの搬送路底面２１ｄから上方に進出したときは、搬送路２１ａで搬送される硬貨は分岐部材２７により搬送路底面２１ｄから図３における上方に持ち上げられ、この硬貨は開口２５に入ることとなる。このように、搬送される硬貨が搬送路底面２１ｄに沿って搬送されているときに該硬貨が開口２５に入ることなく通過する。一方、分岐部材２７によって硬貨が搬送路底面２１ｄから離れたときには該硬貨が開口２５に入り選別されるため、搬送路底面２１ｄが選別のための基準面を形成することとなる。このとき、弾性変形部３３ｂの弾性復元作用により硬貨をその基準面に寄せつつ搬送することができる。さらに、弾性変形部３３ｂの弾性復元作用は、硬貨が分岐部材２７により選別されたときに該硬貨を開口２５に落とし込むという作用も備えている。 Further, branch members 27 are provided below the openings 25 respectively. Each branch member 27 is normally located below the bottom surface 21d of the transport path in the transport path 21a, and is configured to advance above the bottom surface 21d of the transport path when sorting coins. More specifically, when the branch member 27 is located below the bottom 21d of the transport path 21a and the highest position of the branch member 27 is at the same height as the bottom 21d of the transport path, the transport is performed. The coin transported in the path 21a is not pushed upward from the bottom surface 21d of the transport path by the branch member 27. For this reason, the coin conveyed by the conveyance path 21 a does not enter the opening 25. On the other hand, when the branch member 27 advances upward from the bottom surface 21d of the transport path 21a, the coin transported by the transport path 21a is lifted by the branch member 27 upward from the bottom surface 21d of the transport path in FIG. Will enter the opening 25. As described above, when the conveyed coin is conveyed along the bottom surface 21 d of the conveyance path, the coin passes without entering the opening 25. On the other hand, when the coin is separated from the bottom surface 21d of the transport path by the branch member 27, the coin enters the opening 25 and is sorted, so that the bottom surface 21d of the transport path forms a reference surface for sorting. At this time, the coin can be conveyed while being brought close to the reference surface by the elastic restoring action of the elastic deformation portion 33b. Furthermore, the elastic restoring action of the elastic deformation portion 33 b also has an action of dropping the coin into the opening 25 when the coin is sorted by the branch member 27.
　このように、各選別部２４は開口２５、分岐部材２７等から構成されており、分岐部材２７が搬送路底面２１ｄから上方に進出するか否かを制御部８０により制御することにより、各選別部２４は硬貨の選別を行うようになっている。 As described above, each sorting unit 24 includes the opening 25 and the branching member 27 and the like, and the control unit 80 controls whether or not the branching member 27 advances upward from the bottom surface 21 d of the conveyance path. The unit 24 is adapted to sort coins.
　上部搬送部分２０ａにおいて各選別部２４により選別されなかった硬貨は折り返し搬送部分２０ｂに送られるようになる。ここで、折り返し搬送部分２０ｂは、図１および図３に示すように、硬貨入金機１０を側方から見て円弧形状となっている。そして、折り返し搬送部分２０ｂにおいて、硬貨は自重による落下によって上部搬送部分２０ａから下部搬送部分２０ｃに搬送されるようになっている。 Coins not sorted by the sorting units 24 in the upper transport portion 20a are sent to the folded transport portion 20b. Here, as shown in FIG. 1 and FIG. 3, the folded conveying portion 20 b has an arc shape when the coin depositing machine 10 is viewed from the side. And in the return conveyance part 20b, a coin is conveyed by the fall by dead weight from the upper conveyance part 20a to the lower conveyance part 20c.
　下部搬送部分２０ｃは、折り返し搬送部分２０ｂから硬貨が送られる第１搬送部分２０ｄと、硬貨の搬送方向における第１搬送部分２０ｄの下流側に設けられた第２搬送部分２０ｅとから構成されている。より詳細には、第１搬送部分２０ｄには搬送ベルト２１ｅが設けられており、第２搬送部分２０ｅにも搬送ベルト２１ｆが設けられている。第１搬送部分２０ｄに設けられた搬送ベルト２１ｅは、折り返し搬送部分２０ｂにおいて自重による落下によって上部搬送部分２０ａから送られた硬貨を図３における左方向に搬送するようになっている。また、第２搬送部分２０ｅに設けられた搬送ベルト２１ｆは、搬送ベルト２１ｅにより搬送される硬貨が受け渡されるようになっており、この搬送ベルト２１ｆは、搬送ベルト２１ｅから受け渡された硬貨を図３における左方向に搬送するようになっている。本実施形態では、搬送ベルト２１ｅおよび搬送ベルト２１ｆは、後述するベルト３３と同様の構造のものを用いることができる。 The lower conveyance portion 20c is configured of a first conveyance portion 20d to which coins are fed from the folded conveyance portion 20b, and a second conveyance portion 20e provided on the downstream side of the first conveyance portion 20d in the coin conveyance direction. . More specifically, the first conveyance portion 20d is provided with the conveyance belt 21e, and the second conveyance portion 20e is also provided with the conveyance belt 21f. The conveyance belt 21e provided in the first conveyance portion 20d is configured to convey the coin, which is sent from the upper conveyance portion 20a by the fall by its own weight in the folded conveyance portion 20b, in the left direction in FIG. Further, the conveyance belt 21f provided in the second conveyance portion 20e is configured to receive coins conveyed by the conveyance belt 21e, and the conveyance belt 21f is configured to receive coins transferred from the conveyance belt 21e. The sheet is conveyed in the left direction in FIG. In the present embodiment, the conveyor belt 21e and the conveyor belt 21f can have the same structure as the belt 33 described later.
　なお、第２搬送部分２０ｅに設けられた搬送ベルト２１ｆによる硬貨の搬送速度は、第１搬送部分２０ｄに設けられた搬送ベルト２１ｅによる硬貨の搬送速度よりも大きくなっている。このため、第１搬送部分２０ｄに設けられた搬送ベルト２１ｅから第２搬送部分２０ｅに設けられた搬送ベルト２１ｆに硬貨が受け渡される際に硬貨間隔が広くなり、確実に硬貨を選別できると共に、ジャム等のトラブルが発生することなくスムーズに硬貨の受け渡しを行うことができるようになる。 In addition, the conveyance speed of the coin by the conveyance belt 21f provided in the 2nd conveyance part 20e is larger than the conveyance speed of the coin by the conveyance belt 21e provided in the 1st conveyance part 20d. For this reason, when coins are delivered from the transport belt 21e provided in the first transport portion 20d to the transport belt 21f provided in the second transport portion 20e, the coin interval becomes wide, and coins can be sorted reliably. Coins can be delivered smoothly without any problems such as jamming.
　下部搬送部分２０ｃには、上部搬送部分２０ａの搬送路２１ａと同様の構成の搬送路が設けられている。また、下部搬送部分２０ｃにおける第２搬送部分２０ｅには３つの選別部２４（選別部２４ｆ～２４ｈ）が設けられている。下部搬送部分２０ｃの第２搬送部分２０ｅに設けられた各選別部２４は、識別部２２による硬貨の識別結果に基づいて、この第２搬送部分２０ｅにより搬送される硬貨を選別して一時保留部４０に送るようになっている。具体的には、各選別部２４ｆ～２４ｈは、金種別に硬貨を選別する金種別選別部として機能するようになっている。より詳細には、例えば本実施形態の硬貨入金機１０においてユーロ（ＥＵＲＯ）硬貨の処理が行われるときに、硬貨の搬送方向において最も上流側に配置された選別部２４ｆは、識別部２２により２ユーロ硬貨であると識別された硬貨を選別し、硬貨の搬送方向において上流側から２番目に配置された選別部２４ｇは、識別部２２により１ユーロ硬貨であると識別された硬貨を選別する。また、硬貨の搬送方向において上流側から３番目に配置された選別部２４ｈは、識別部２２により２セント硬貨であると識別された硬貨を選別するようになっている。さらに、下部搬送部分２０ｃの第２搬送部分２０ｅにおいて、硬貨の搬送方向におけるこれらの３つの選別部２４ｆ～２４ｈの下流側には開口２４ｉが設けられており、この開口２４ｉには、各選別部２４ｆ～２４ｈにより選別されなかった硬貨、具体的には例えば２０セント硬貨が入るようになっている。なお、この開口２４ｉにもシュート２６が接続されており、開口２４ｉに入った２０セント硬貨はシュート２６を介して一時保留部４０に送られるようになっている。 The lower conveyance portion 20c is provided with a conveyance path having the same configuration as the conveyance path 21a of the upper conveyance portion 20a. Further, three sorting units 24 (sorting units 24f to 24h) are provided in the second transport portion 20e in the lower transport portion 20c. Each sorting unit 24 provided in the second transport portion 20e of the lower transport portion 20c sorts the coins transported by the second transport portion 20e based on the identification result of the coin by the identification unit 22 and stores the temporary storage portion It is supposed to be sent to 40. Specifically, the sorting units 24f to 24h function as denomination sorting units that sort coins according to denominations. More specifically, for example, when processing of Euro (EURO) coins is performed in the coin depositing machine 10 of the present embodiment, the sorting unit 24f disposed most upstream in the coin transport direction is A coin identified as a euro coin is sorted, and the sorting unit 24g disposed second from the upstream side in the coin transport direction sorts coins identified as a 1 euro coin by the identification unit 22.

The chute 26 is also connected to the opening 24i, and the 20-cent coin that has entered the opening 24i is sent to the temporary storage unit 40 via the chute 26.
（搬送無端ベルト）
　ベルト３３は、硬貨搬送円盤３２の上の硬貨を押圧保持して移動させ、重送硬貨の捌きを行うと共に、入金搬送部２０において硬貨を押圧保持して搬送する。具体的には、ベルト３３は、摩擦搬送部位３２ｃの上面の硬貨に接触して弾性変形し、硬貨を段差部位３２ｄに向けて移動させた後、硬貨搬送円盤３２の外部となる入金搬送部２０の搬送路２１ａにおいて硬貨を搬送する。 (Conveying endless belt)
The belt 33 presses and holds the coin on the coin conveyance disk 32 and moves it to unfold the double-fed coin, and presses and holds the coin in the deposit / conveyance unit 20 to convey it. Specifically, the belt 33 contacts the coin on the upper surface of the friction transfer portion 32c to be elastically deformed, and after moving the coin toward the step portion 32d, the deposit transfer portion 20 which becomes the outside of the coin transfer disk 32. The coin is transported in the transport path 21a of
　本実施形態におけるベルト３３は、図３に示すように、第１プーリー３４ａと第２プーリー３４ｅとの間に掛け回されて、第１プーリー３４ａによって駆動され、移動する。図４～図６に示すように、ベルト３３は、環状に構成されており、本体部３３ａと、本体部３３ａから幅方向Ｗ（図５の断面長手方向）に延出した弾性変形部３３ｂと、を有している。これら本体部３３ａおよび弾性変形部３３ｂは、ゴム等の同一材料で構成されている。以下、ベルト３３が硬貨を搬送する方向を「周方向Ｒｏ」とし、ベルト３３の幅方向Ｗおよび周方向Ｒｏと垂直な方向を「径方向Ｒａ」（ベルト３３の厚さ方向）として説明する。これは、ベルト３３が環状に構成されていることから、ベルト３３を基準とした「周方向Ｒｏ」、「径方向Ｒａ」として定義しているものである。 As shown in FIG. 3, the belt 33 in the present embodiment is wound around a first pulley 34a and a second pulley 34e, driven by the first pulley 34a, and moved. As shown in FIGS. 4 to 6, the belt 33 is formed in an annular shape, and includes a main body portion 33a and an elastically deformable portion 33b extending from the main body portion 33a in the width direction W (the longitudinal direction of the cross section in FIG. 5). ,have. The main body 33a and the elastically deformable portion 33b are made of the same material such as rubber. Hereinafter, the direction in which the belt 33 transports coins is referred to as “circumferential direction Ro”, and the direction perpendicular to the width direction W of the belt 33 and the circumferential direction Ro is referred to as “radial direction Ra” (thickness direction of the belt 33). This is defined as "circumferential direction Ro" and "radial direction Ra" with reference to the belt 33, since the belt 33 is formed in an annular shape.
　本体部３３ａは、ベルト３３の搬送方向に垂直な方向の断面が径方向Ｒａよりも幅方向Ｗが大きい矩形状に構成されている（図５～図６参照）。本体部３３ａの内周面には、第１プーリー３４ａの外周面に形成された複数の凹状部３４ａ１と噛み合う複数の凸状部３３ａ１が形成されている。また、本体部３３ａの内周面には、幅方向Ｗの一対の凸状部３３ａ１の間に、第１プーリー３４ａの外周面の中央部分に形成された環状凸部３４ａ２に係合する環状溝３３ａ２が形成されている。つまり、第１プーリー３４ａの複数の凹状部３４ａ１に本体部３３ａの複数の凸状部３３ａ１が噛み合うと共に、本体部３３ａの環状溝３３ａ２が、第１プーリー３４ａの環状凸部３４ａ２に係合することにより、本体部３３ａが第１プーリー３４ａに支持されている。なお、第２プーリー３４ｅが本体部３３ａと噛み合う構成は、第１プーリー３４ａと同様であるため、説明を省略する。 The main body portion 33a is formed in a rectangular shape in which a cross section in a direction perpendicular to the conveyance direction of the belt 33 is larger in the width direction W than the radial direction Ra (see FIGS. 5 to 6). On the inner peripheral surface of the main body portion 33a, a plurality of convex portions 33a1 are formed to engage with the plurality of concave portions 34a1 formed on the outer peripheral surface of the first pulley 34a. Further, on the inner peripheral surface of the main body portion 33a, an annular groove engaged with the annular convex portion 34a2 formed in the central portion of the outer peripheral surface of the first pulley 34a between the pair of convex portions 33a1 in the width direction W 33a2 is formed. That is, while the plurality of convex portions 33a1 of the main body portion 33a mesh with the plurality of concave portions 34a1 of the first pulley 34a, the annular groove 33a2 of the main body portion 33a engages with the annular convex portion 34a2 of the first pulley 34a. Thus, the main body 33a is supported by the first pulley 34a. The configuration in which the second pulley 34e meshes with the main body 33a is the same as that of the first pulley 34a, so the description will be omitted.
　また、本実施形態における本体部３３ａの径方向Ｒａ中央部分には、周方向Ｒｏに伸縮しない布、樹脂等で構成される芯体３３ｃが埋設されている。この芯体３３ｃは、複数の環状糸状部材が幅方向Ｗに複数並列する状態で構成されている。「周方向Ｒｏに伸縮しない芯体３３ｃ」とは、ベルト駆動機構３４の駆動力ではほぼ伸縮しない芯体３３ｃを意味し、所定値以上の大きな応力で引っ張った場合には伸縮する芯体３３ｃも含まれる。 Further, in the central portion of the main body portion 33a in the radial direction Ra in the present embodiment, a core 33c made of a cloth, a resin, or the like that does not extend and contract in the circumferential direction Ro is embedded. The core body 33c is configured such that a plurality of annular thread members are arranged in parallel in the width direction W. The term “core 33c that does not expand and contract in the circumferential direction Ro” means the core 33c that does not expand and contract substantially by the driving force of the belt drive mechanism 34, and the core 33c that expands and contracts when pulled by a large stress greater than a predetermined value included.
　弾性変形部３３ｂは、断面が長方形であり、ベルト３３において弾性変形が可能なように構成された部位である。弾性変形部３３ｂは、本体部３３ａよりも少なくとも径方向Ｒａの弾性率（変形のしにくさを表す物性値、剪断変形率，引張弾性率および体積弾性率の少なくとも１つ）が小さく構成されている。本実施形態の弾性変形部３３ｂは、本体部３３ａよりも径方向Ｒａの厚さを小さく形成することにより、本体部３３ａよりも弾性率を小さく構成している。この弾性変形部３３ｂの厚さは、本体部３３ａに埋設された芯体３３ｃが含まれない領域に設定されており、本体部３３ａの厚さの３分の１以下に設定されている。なお、弾性変形部３３ｂの厚さを本体部３３ａと同等とに構成して、芯体３３ｃの有無により弾性率を異ならせてもよい。 The elastically deformable portion 33 b has a rectangular cross section, and is a portion of the belt 33 configured to be elastically deformable. The elastic deformation portion 33b is configured to have a smaller elastic modulus (a physical property value indicating difficulty in deformation, at least one of a shear deformation rate, a tensile elastic modulus and a bulk elastic modulus) at least in the radial direction Ra than the main body 33a. There is. The elastic deformation portion 33b of the present embodiment is configured to have a smaller elastic modulus than the main body portion 33a by forming the thickness in the radial direction Ra smaller than the main body portion 33a. The thickness of the elastically deformable portion 33b is set in a region not including the core body 33c embedded in the main body portion 33a, and is set to one third or less of the thickness of the main body portion 33a. The thickness of the elastically deformable portion 33b may be equal to that of the main portion 33a, and the elastic modulus may be made different depending on the presence or absence of the core 33c.
　弾性変形部３３ｂの幅方向Ｗの長さ、すなわち弾性変形部３３ｂが本体部３３ａから延出している長さは、硬貨繰出装置３０が搬送対象物となる複数種類の硬貨の最大厚さよりも大きい。また、弾性変形部３３ｂの幅方向Ｗの長さは、径方向Ｒａの厚さよりも大きく構成されており、径方向Ｒａの厚さの５倍以上に設定されている。さらに、弾性変形部３３ｂは周方向Ｒｏに接続された環状に形成されていることから、ベルト３３の径方向Ｒａについての弾性変形部３３ｂの曲げ剛性が、ベルト３３の周方向Ｒｏ（ベルト３３の走行方向）についての弾性変形部３３ｂの曲げ剛性よりも小さくなっている。 The length in the width direction W of the elastically deformable portion 33b, that is, the length in which the elastically deformable portion 33b extends from the main body portion 33a, is larger than the maximum thickness of the plurality of types of coins with which the coin feeding device 30 is to be transported. . The length in the width direction W of the elastically deformable portion 33b is larger than the thickness in the radial direction Ra, and is set to be five times or more the thickness in the radial direction Ra. Furthermore, since the elastically deformable portion 33 b is formed in an annular shape connected in the circumferential direction Ro, the bending rigidity of the elastically deformable portion 33 b with respect to the radial direction Ra of the belt 33 is the circumferential direction Ro of the belt 33 (the belt 33 It is smaller than the bending rigidity of the elastically deformable portion 33b in the traveling direction).
（ベルト駆動機構）
　ベルト駆動機構３４は、ベルト３３を硬貨搬送円盤３２の内側に向けて移動させる（図１０～図１１参照）。本実施形態のベルト駆動機構３４は、図３に示すように、第１プーリー３４ａ、上面押圧プーリー３４ｃ、側面押圧プーリー３４ｄおよび第２プーリー３４ｅを有して構成される。 (Belt drive mechanism)
The belt drive mechanism 34 moves the belt 33 toward the inside of the coin transport disk 32 (see FIGS. 10 to 11). As shown in FIG. 3, the belt drive mechanism 34 of the present embodiment is configured to have a first pulley 34a, an upper surface pressing pulley 34c, a side surface pressing pulley 34d and a second pulley 34e.
　第１プーリー３４ａは、その回転軸３４ｂがベース部材３１および硬貨搬送円盤３２と垂直になる姿勢にて、ベース部材３１の上に配置される。第２プーリー３４ｅは、その回転軸が硬貨搬送円盤３２と垂直になる姿勢にて、入金搬送部２０に配置される。ここで硬貨搬送円盤３２の回転軸３２ａも同様にベース部材３１と垂直であるから、第１プーリー３４ａの回転軸３４ｂは硬貨搬送円盤３２の回転軸３２ａと平行である。第１プーリー３４ａはモータ（図示なし）により、回転軸３４ｂの回りに回転駆動される。 The first pulley 34 a is disposed on the base member 31 such that its rotation axis 34 b is perpendicular to the base member 31 and the coin transport disk 32. The second pulley 34 e is disposed in the depositing and conveying unit 20 in a posture in which the rotation axis is perpendicular to the coin conveying disk 32. Here, since the rotation shaft 32 a of the coin transport disk 32 is also perpendicular to the base member 31, the rotation shaft 34 b of the first pulley 34 a is parallel to the rotation shaft 32 a of the coin transport disk 32. The first pulley 34a is rotationally driven around a rotation shaft 34b by a motor (not shown).
　上面押圧プーリー３４ｃは、その回転軸がベース部材３１と平行になる姿勢にて、ベルト３３の上面に接する状態で配置される。上面押圧プーリー３４ｃは、ベルト３３が硬貨と接触して弾性変形することによる上方向（幅方向Ｗ）への移動を抑制する。 The upper surface pressing pulley 34 c is disposed in contact with the upper surface of the belt 33 in a posture in which the rotation axis is parallel to the base member 31. The upper surface pressing pulley 34 c suppresses the movement in the upward direction (width direction W) due to the belt 33 coming into contact with the coin and elastically deforming.
　側面押圧プーリー３４ｄは、その回転軸がベース部材３１と垂直になる姿勢にて、ベルト３３の側面に接する状態で配置される。側面押圧プーリー３４ｄは、ベルト３３が硬貨と接触して弾性変形することによる横方向（径方向Ｒａ）への移動を抑制する。 The side pressing pulley 34 d is disposed in contact with the side surface of the belt 33 in a posture in which the rotation axis is perpendicular to the base member 31. The side surface pressing pulley 34d suppresses the movement in the lateral direction (radial direction Ra) due to the belt 33 coming into contact with the coin and elastically deforming.
　ここで図３および図６を参照して、ベルト３３およびベルト駆動機構３４による硬貨の搬送について説明する。図６は、硬貨搬送円盤３２の上面と平行な方向から見た、ベルト３３による硬貨の押圧および搬送の状態を示す説明図である。 Here, with reference to FIG. 3 and FIG. 6, conveyance of the coin by the belt 33 and the belt drive mechanism 34 is demonstrated. FIG. 6 is an explanatory view showing a state of pressing and conveyance of coins by the belt 33 as viewed from a direction parallel to the upper surface of the coin conveyance disk 32. As shown in FIG.
　ベルト駆動機構３４の第１プーリー３４ａおよび第２プーリー３４ｅが回転駆動されると、ベルト３３は、第１プーリー３４ａおよび第２プーリー３４ｅの周りを図３に示される矢印の方向（周方向Ｒｏ）、すなわち図３で反時計回りに走行（移動）する。詳しくは、ベルト３３は、ベルト駆動機構３４により次のように移動（走行）する。 When the first pulley 34a and the second pulley 34e of the belt drive mechanism 34 are rotationally driven, the belt 33 rotates around the first pulley 34a and the second pulley 34e in the direction of the arrow shown in FIG. 3 (circumferential direction Ro). That is, it travels (moves) counterclockwise in FIG. Specifically, the belt 33 moves (travels) by the belt drive mechanism 34 as follows.
　まず、ベルト３３は第１プーリー３４ａの外周に沿って移動し、硬貨搬送円盤３２の上側から回転軸３２ａに向けて、すなわち直径方向に向けて進入する。そしてベルト３３は、第１プーリー３４ａの外周に沿って移動方向を徐々に変化させる。換言すれば、ベルト３３は第１プーリー３４ａの回転軸３４ｂを中心とする円軌道に沿って移動する。このときベルト３３は、硬貨搬送円盤３２の段差部位３２ｄの近傍を走行する。続いてベルト３３は、第１プーリー３４ａから離れて第２プーリー３４ｅに向けて図３の右方向に移動し、硬貨搬送円盤３２の上から退出する。換言すれば、ベルト３３は硬貨搬送円盤３２の上から硬貨搬送円盤３２の外部へ移動（走行）する。次いでベルト３３は、入金搬送部２０に進入し、識別部２２を通り、搬送路２１ａを走行する。そしてベルト３３は、第２プーリー３４ｅの外周に沿って移動して、第１プーリー３４ａへと循環する。 First, the belt 33 moves along the outer periphery of the first pulley 34a, and enters from the upper side of the coin conveyance disk 32 toward the rotation shaft 32a, that is, in the radial direction. Then, the belt 33 gradually changes the moving direction along the outer periphery of the first pulley 34a. In other words, the belt 33 moves along a circular orbit centered on the rotation axis 34b of the first pulley 34a. At this time, the belt 33 travels in the vicinity of the stepped portion 32 d of the coin transport disk 32. Subsequently, the belt 33 moves away from the first pulley 34 a and moves toward the second pulley 34 e in the right direction of FIG. 3 and withdraws from above the coin transport disk 32. In other words, the belt 33 moves (travels) from the top of the coin transport disc 32 to the outside of the coin transport disc 32. Next, the belt 33 enters the depositing and conveying unit 20, passes through the identification unit 22, and travels along the conveying path 21a. Then, the belt 33 moves along the outer periphery of the second pulley 34e and circulates to the first pulley 34a.
　硬貨搬送円盤３２によってベルト３３に向けて搬送されてきた硬貨Ｃ３２は、ベルト３３と接触して、ベルト３３の弾性復元作用によって段差部位３２ｄへ向けて押し付けられ、段差部位３２ｄと接触し、ベルト３３の下側（すなわちベルト３３と硬貨搬送円盤３２との間）に潜り込む（図６に示す硬貨Ｃ３２の状態）。 The coin C32 transported toward the belt 33 by the coin transport disk 32 comes in contact with the belt 33, is pushed toward the stepped portion 32d by the elastic restoring action of the belt 33, contacts the stepped portion 32d, and is belt 33 (Ie, between the belt 33 and the coin transport disk 32) (the state of the coin C32 shown in FIG. 6).
　換言すれば、ベルト３３が、第１プーリー３４ａの外周に沿って段差部位３２ｄに向けて移動してきた際、硬貨Ｃ３２が硬貨搬送円盤３２によってベルト３３に向けて移動し、硬貨Ｃ３２がベルト３３に接触する。硬貨Ｃ３２は、段差部位３２ｄに当接した状態で、硬貨搬送円盤３２と共に回転して図３の右方向へ移動するから、硬貨Ｃ３２がベルト３３を第１プーリー３４ａの回転軸３４ｂに向かって、すなわち第１プーリー３４ａの内側に向かって押すことになる。そうするとベルト３３は、第１プーリー３４ａの回転軸３４ｂに向かって、すなわち第１プーリー３４ａの内側（径方向Ｒａ内方）に向かって弾性変形する。そしてベルト３３は、第１プーリー３４ａの外周に沿って移動し、硬貨Ｃ３２の上側へと移動する（図６に示す硬貨Ｃ３２の状態）。 In other words, when the belt 33 moves along the outer periphery of the first pulley 34a toward the step portion 32d, the coin C32 moves toward the belt 33 by the coin transport disc 32, and the coin C32 is transferred to the belt 33. Contact. The coin C32 rotates with the coin transport disk 32 and moves in the right direction of FIG. 3 in the state of contacting the step portion 32d, so that the coin C32 moves the belt 33 toward the rotation shaft 34b of the first pulley 34a. That is, it pushes inward of the first pulley 34a. Then, the belt 33 elastically deforms toward the rotation shaft 34b of the first pulley 34a, that is, inward (inward in the radial direction Ra) of the first pulley 34a. Then, the belt 33 moves along the outer periphery of the first pulley 34a, and moves to the upper side of the coin C32 (the state of the coin C32 shown in FIG. 6).
　図６に示す硬貨Ｃ３２の状態は、硬貨Ｃ３２がベルト３３、詳しくはベルト３３の弾性変形部３３ｂの端部３３ｂ１を弾性変形させて、ベルト３３と硬貨搬送円盤３２との間に潜り込んだ状態を示している。このときベルト３３の複数の弾性変形部３３ｂの端部３３ｂ１が、硬貨Ｃ３２により、弾性変形部３３ｂの幅方向Ｗの中程で折れ曲がり、第１プーリー３４ａの径方向Ｒａ内方に向かって弾性変形した状態となる。そして硬貨Ｃ３２は、弾性変形した弾性変形部３３ｂの端部３３ｂ１の側面によって、摩擦搬送部位３２ｃの上面に向けて押圧保持されている。この硬貨Ｃ３２は、弾性変形部３３ｂの弾性復元作用により、段差部位３２ｄの外周面３２ｅに寄せられて当接している。 The state of the coin C32 shown in FIG. 6 is a state in which the coin C32 elastically deforms the belt 33, and more specifically, the end 33b1 of the elastic deformation portion 33b of the belt 33, and gets into the space between the belt 33 and the coin conveyance disc 32. It shows. At this time, the end 33b1 of the plurality of elastically deformable portions 33b of the belt 33 is bent in the middle of the width direction W of the elastically deformable portion 33b by the coin C32, and elastically deformed inward in the radial direction Ra of the first pulley 34a. It will be in a state of The coin C32 is pressed and held by the side surface of the end 33b1 of the elastically deformed portion 33b elastically deformed toward the upper surface of the friction transfer portion 32c. The coin C32 is brought close to and in contact with the outer peripheral surface 32e of the stepped portion 32d by the elastic restoring action of the elastic deformation portion 33b.
　図６に示す硬貨Ｃ３３の状態は、硬貨Ｃ３２よりも薄く小さい硬貨がベルト３３と硬貨搬送円盤３２との間に潜り込んだ状態を示している。このとき、弾性変形部３３ｂが、硬貨Ｃ３４により先端付近で折れ曲がり、第１プーリー３４ａの径方向Ｒａ内方に向かって弾性変形している。そして硬貨Ｃ３３は、弾性変形した弾性変形部３３ｂの端部３３ｂ１の側面によって、摩擦搬送部位３２ｃの上面に向けて押圧保持されている。この硬貨Ｃ３３は、弾性変形部３３ｂの弾性復元作用により、案内部材３８の内面３８ａに寄せられて当接している。 The state of the coin C33 shown in FIG. 6 shows a state in which a coin thinner and smaller than the coin C32 is submerged between the belt 33 and the coin transport disk 32. At this time, the elastically deformable portion 33 b is bent near the tip by the coin C 34 and elastically deformed inward in the radial direction Ra of the first pulley 34 a. The coin C33 is pressed and held by the side surface of the end 33b1 of the elastically deformed elastic deformation portion 33b toward the upper surface of the friction transfer portion 32c. The coin C33 is brought close to and in contact with the inner surface 38a of the guide member 38 by the elastic restoring action of the elastically deformable portion 33b.
　図６に示す硬貨Ｃ３４の状態は、硬貨Ｃ３２よりも厚く大きい硬貨がベルト３３とベース部材３１（搬送路２１ａ）との間に潜り込んだ状態を示している。このとき、弾性変形部３３ｂが、硬貨Ｃ３４により幅方向Ｗの上部付近で折れ曲がり、第１プーリー３４ａの径方向Ｒａ内方に向かって弾性変形している。そして硬貨Ｃ３４は、弾性変形した弾性変形部３３ｂによって、ベース部材３１（搬送路２１ａの搬送路側面２１ｃ）に向けて押圧されている。この硬貨Ｃ３４は、弾性変形部３３ｂの弾性復元作用により、搬送路２１ａの搬送路底面２１ｄに寄せられて当接している。このように、径方向Ｒａ内方に弾性変形する弾性変形部３３ｂの弾性復元作用により、摩擦搬送部位３２ｃ又は搬送路２１ａの一方側に形成された段差部位３２ｄの外周面３２ｅ，案内部材３８の内面３８ａ又は搬送路底面２１ｄに硬貨を寄せつつ搬送するので、硬貨を一列に整列させた状態で搬送することができる。 The state of the coin C34 shown in FIG. 6 shows a state in which a coin which is thicker than the coin C32 is embedded between the belt 33 and the base member 31 (conveying path 21a). At this time, the elastically deformable portion 33b is bent near the upper portion in the width direction W by the coin C34, and is elastically deformed inward in the radial direction Ra of the first pulley 34a. Then, the coin C34 is pressed toward the base member 31 (the conveyance path side surface 21c of the conveyance path 21a) by the elastically deformed elastically deformable portion 33b. The coin C34 is brought close to and in contact with the bottom surface 21d of the conveyance path 21a by the elastic restoring action of the elastically deformable portion 33b. As described above, due to the elastic restoring action of the elastically deformable portion 33b elastically deformed inward in the radial direction Ra, the outer peripheral surface 32e of the stepped portion 32d formed on one side of the friction conveyance portion 32c or the conveyance path 21a The coins are transported while being brought close to the inner surface 38a or the transport path bottom surface 21d, so that the coins can be transported in a line.
　ベルト３３の弾性変形部３３ｂが硬貨Ｃ３４によって変形している領域の長さ（ベルト３３の周方向Ｒｏに沿った長さ）は、硬貨Ｃ３３によって変形している領域の長さよりも大きい。また、弾性変形部３３ｂの硬貨Ｃ３４による径方向Ｒａ内方への変形量（例えば、折れ曲がった部分の長さ）は、硬貨Ｃ３３による変形量よりも大きい。このように、ベルト３３（弾性変形部３３ｂ）は、接触する硬貨の大きさおよび厚さに応じて弾性変形する。本実施形態では、弾性変形部３３ｂの弾性率が本体部３３ａの弾性率よりも小さく構成されているため、弾性変形部３３ｂの硬貨Ｃ３４による変形によって生じる空間は、隣り合う硬貨Ｃ３３まで影響しない。同様に、弾性変形部３３ｂの硬貨Ｃ３２による変形によって生じる空間は、隣り合う硬貨Ｃ３３まで影響しない。よって、本実施形態のベルト３３を用いることにより、厚さの異なる硬貨Ｃ３２，Ｃ３３，Ｃ３４であっても、夫々の硬貨Ｃ３２，Ｃ３３，Ｃ３４を確実に押圧保持することができる。 The length of the area (length along the circumferential direction Ro of the belt 33) in which the elastic deformation portion 33b of the belt 33 is deformed by the coin C34 is larger than the length of the area deformed by the coin C33. Further, the amount of deformation (for example, the length of the bent portion) of the elastically deformable portion 33b in the radial direction Ra by the coin C34 is larger than the amount of deformation of the coin C33. Thus, the belt 33 (elastically deformable portion 33b) is elastically deformed in accordance with the size and thickness of the contacting coin. In the present embodiment, since the elastic modulus of the elastically deformable portion 33b is smaller than the elastic modulus of the main portion 33a, the space generated by the deformation of the elastically deformable portion 33b by the coin C34 does not affect the adjacent coin C33. Similarly, the space generated by the deformation of the elastically deformable portion 33b by the coin C32 does not affect the adjacent coin C33. Therefore, by using the belt 33 of the present embodiment, the coins C32, C33, and C34 can be reliably pressed and held, even for the coins C32, C33, and C34 having different thicknesses.
　硬貨搬送円盤３２および搬送路２１ａと、弾性変形部３３ｂの先端との間の距離Ｄ１（所定間隔の一例）は、複数種類の硬貨の最小厚さより小さい。すなわち、硬貨搬送円盤３２の上面および搬送路２１ａの搬送路側面２１ｃと、ベルト３３の端部３３ｂ１との間の距離Ｄ１は、硬貨繰出装置３０が処理の対象とする処理対象硬貨の最小の厚さより小さい。また、硬貨搬送円盤３２と、弾性変形部３３ｂの根元との間の距離Ｄ２は、複数種類の硬貨の最大厚さより大きい。これにより、処理対象硬貨のうち最も厚さが小さい硬貨であっても、弾性変形部３３ｂの端部３３ｂ１が押圧保持して、当該硬貨を搬送することができる。また、処理対象硬貨のうち最も厚さが大きい硬貨であっても、当該硬貨が本体部３３ａに接触せず、当該硬貨によって弾性変形部３３ｂが弾性変形することができる。 Distance D1 (an example of a predetermined interval) between coin conveyance disk 32 and conveyance way 21a and the tip of elastic deformation part 33b is smaller than the minimum thickness of a plurality of kinds of coins. That is, the distance D1 between the upper surface of the coin transport disk 32, the transport path side 21c of the transport path 21a, and the end 33b1 of the belt 33 is the minimum thickness of the processing object coin to be processed by the coin feeding device 30. Less than. Further, the distance D2 between the coin transport disk 32 and the root of the elastic deformation portion 33b is larger than the maximum thickness of a plurality of types of coins. Thereby, even if it is a coin with the smallest thickness among coins to be processed, the end 33b1 of the elastically deformable portion 33b can be pressed and held, and the coin can be transported. In addition, even if the coin to be processed is the coin with the largest thickness, the coin does not contact the main body 33a, and the elastically deformable portion 33b can be elastically deformed by the coin.
　そして図６に示すように、弾性変形部３３ｂによって押圧された硬貨Ｃ３２、Ｃ３３、Ｃ３４は、ベルト駆動機構３４によるベルト３３の移動に伴い、摩擦搬送部位３２ｃの上面から搬送路２１ａの搬送路側面２１ｃ、すなわち硬貨搬送円盤３２の外部へ移動し、入金搬送部２０へと移動する。このとき、弾性率の小さい弾性変形部３３ｂの端部３３ｂ１を径方向Ｒａ内方に変形させることにより硬貨Ｃ３２、Ｃ３３、Ｃ３４を保持するので、全体的にベルト３３が撓むことなく、弾性変形部３３ｂの端部３３ｂ１に保持された硬貨Ｃ３２、Ｃ３３、Ｃ３４と隣接する部位には、弾性変形部３３ｂの変形により生じる空間を最小限とすることが可能となる。しかも、本実施形態のように本体部３３ａに周方向Ｒｏに伸縮しない芯体３３ｃを埋設すれば、弾性変形部３３ｂの捻れに連動して本体部３３ａが捻れるといったことが無い。その結果、硬貨Ｃ３２、Ｃ３３、Ｃ３４を押圧する弾性変形部３３ｂの変形により生じる空間が、本体部３３ａの捻れによって拡大されるといった不都合を防止できる。よって、硬貨搬送円盤３２から複数の硬貨Ｃ３２、Ｃ３３、Ｃ３４が連なって移動してきた場合でも、これらの硬貨Ｃ３２、Ｃ３３、Ｃ３４を搬送路２１ａで円滑に搬送することができる。 Then, as shown in FIG. 6, the coins C32, C33 and C34 pressed by the elastic deformation portion 33b are moved from the upper surface of the friction transfer portion 32c to the side surface of the transfer path 21a as the belt 33 moves by the belt drive mechanism 34. 21c, that is, move to the outside of the coin transfer disk 32 and move to the deposit transfer unit 20. At this time, since the coins C32, C33, and C34 are held by deforming the end 33b1 of the elastic deformation portion 33b having a small elastic modulus inward in the radial direction Ra, the belt 33 does not bend as a whole and is elastically deformed. In the portion adjacent to the coins C32, C33, and C34 held at the end 33b1 of the portion 33b, it is possible to minimize the space generated by the deformation of the elastically deformable portion 33b. Moreover, if the core 33c which does not expand and contract in the circumferential direction Ro is embedded in the main body portion 33a as in the present embodiment, there is no possibility that the main body portion 33a is twisted in conjunction with the twisting of the elastically deformable portion 33b. As a result, it is possible to prevent such a disadvantage that the space generated by the deformation of the elastically deformable portion 33b pressing the coins C32, C33, and C34 is enlarged by the twisting of the main portion 33a. Therefore, even when a plurality of coins C32, C33, and C34 move in succession from the coin conveyance disk 32, these coins C32, C33, and C34 can be smoothly conveyed on the conveyance path 21a.
（カバー部材）
　図７～図９に示すように、カバー部材３５は、硬貨搬送円盤３２の下部領域を覆う樹脂製の部材であって、硬貨搬送円盤３２との間に硬貨貯留空間３６を形成する。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は、支柱、バネおよび板状部材を有して構成され、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を硬貨搬送円盤３２に向けて付勢している。 (Cover member)
As shown in FIG. 7 to FIG. 9, the cover member 35 is a member made of resin that covers the lower region of the coin transport disk 32, and forms a coin storage space 36 with the coin transport disk 32. The cover member 35 is configured to have an open / close portion 35a, a shaft member 35b and a pressing member 35c, and is attached to the base member 31 via a biasing mechanism 35d. The biasing mechanism 35d is configured to have a support, a spring and a plate-like member, the support is provided on the base member 31, and the plate-like member attached to the support via the spring serves to cover the cover member 35 It is biased towards 32.
　押圧部材３５ｃは金属製の板状の部材であって、硬貨搬送円盤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、かつ、硬貨搬送円盤３２の摩擦搬送部位３２ｃに対向する位置にて、カバー部材３５の硬貨搬送円盤３２側の面に取り付けられる。 The pressing member 35 c is a metal plate-like member, and is formed in a shape that follows the arc of the outer periphery of the coin transport disc 32 and the cover member 35. The pressing member 35c is on the surface of the cover member 35 on the coin transfer disk 32 side at a position where the arc of the outer periphery thereof is along the outer periphery of the cover member 35 and at a position facing the friction transfer portion 32c of the coin transfer disk 32. It is attached.
　ここでカバー部材３５は付勢機構３５ｄにより硬貨搬送円盤３２に向けて付勢されている。すると、図７に示すように押圧部材３５ｃと硬貨搬送円盤３２の摩擦搬送部位３２ｃとの間に硬貨が入り込むと、押圧部材３５ｃが硬貨を硬貨搬送円盤３２に押し付けることになる。 Here, the cover member 35 is biased toward the coin transport disk 32 by the biasing mechanism 35d. Then, as shown in FIG. 7, when a coin is inserted between the pressing member 35 c and the friction transfer portion 32 c of the coin transfer disk 32, the pressing member 35 c presses the coin against the coin transfer disk 32.
　すなわち硬貨繰出装置３０は、押圧部材３５ｃと、付勢機構３５ｄとを有し、押圧部材３５ｃは、硬貨搬送円盤３２の摩擦搬送部位３２ｃに対向する姿勢にて、硬貨搬送円盤３２の下部領域において硬貨搬送円盤３２の上側に配置され、付勢機構３５ｄは、押圧部材３５ｃを硬貨搬送円盤３２に向けて付勢して、押圧部材３５ｃが硬貨を硬貨搬送円盤３２に押し付ける。そうすると、硬貨と摩擦搬送部位３２ｃとの間の摩擦力が増加して、硬貨搬送円盤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、硬貨と摩擦搬送部位３２ｃとの間の摩擦力が増加するから、硬貨搬送円盤３２の回転速度を増加させることが可能となる。 That is, the coin feeding device 30 has a pressing member 35c and an urging mechanism 35d, and the pressing member 35c is in a lower region of the coin transport disk 32 in a posture to face the friction transport portion 32c of the coin transport disk 32. The biasing mechanism 35 d biases the pushing member 35 c toward the coin conveying disc 32 so that the pushing member 35 c presses the coin against the coin conveying disc 32. Then, the frictional force between the coin and the friction transfer portion 32c is increased, and the transfer of the coin by the coin transfer disk 32 is reliably performed. As a result, even when a small number of coins exist in the coin storage space 36, it is possible to reliably carry out the coins, and it is possible to suppress the situation in which the coins which are not drawn out to the coin feeding device 30 remain. In addition, since the frictional force between the coin and the friction transfer portion 32c is increased, the rotational speed of the coin transfer 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、クリップやカギなど）を硬貨貯留空間３６の外部に排出する（図８、図９参照）。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の内部の硬貨の有無を検知する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、センサが硬貨を検知していない際に、開閉部位３５ａを開閉する。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。例えば、硬貨搬送円盤３２を駆動させても硬貨が入金搬送部２０に繰出されない状態で、当該センサが検出信号を出力している場合には、制御部８０は、硬貨貯留空間３６の内部に異物が残留していると判断して、開閉部位３５ａを開閉する。これにより硬貨貯留空間３６の内部の異物が排出される。 The opening and closing portion 35a is a portion formed on the cover member 35, and discharges foreign objects E (for example, a clip and a key) inside the coin storage space 36 to the outside of the coin storage space 36 by opening and closing 8 and 9). The open / close portion 35a of the present embodiment is attached to the cover member 35 through the shaft member 35b, and is driven by a solenoid (not shown) or the like to rotate around the shaft member 35b to perform an opening / closing operation. Discharge of the foreign material E from the coin storage space 36 by opening and closing the opening and closing portion 35 a is performed when coins are not stored inside the coin storage space 36. For example, a sensor for detecting the presence or absence of a coin in 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 open / close portion 35a based on the output of the sensor. For example, when the sensor does not detect a coin, the control unit 80 opens and closes the opening and closing portion 35a. Thus, when there is a foreign matter inside the coin storage space 36, the foreign matter is discharged. For example, when the sensor outputs a detection signal in a state in which coins are not fed out to the depositing and conveying unit 20 even if the coin conveying disk 32 is driven, the control unit 80 detects foreign matter in the coin storage space 36 Is judged to be remaining, and the opening and closing part 35a is opened and closed. Thus, foreign matter in the coin storage space 36 is discharged.
　すなわち硬貨繰出装置３０はカバー部材３５を有し、カバー部材３５は硬貨搬送円盤３２との間に硬貨を収容する硬貨貯留空間３６を形成し、カバー部材３５は硬貨貯留空間３６の異物を排出する開閉部位３５ａを有する。これにより、硬貨貯留空間３６からの異物の排除を可能として、硬貨繰出装置３０の異物の排除能力を更に高めることができ好適である。 That is, the coin feeding device 30 has a cover member 35, and the cover member 35 forms a coin storage space 36 for storing coins between the coin transport disk 32 and the cover member 35 discharges foreign matters in the coin storage space 36. It has an opening and closing part 35a. Thereby, the foreign matter can be removed from the coin storage space 36, and the foreign matter removing capability of the coin feeding device 30 can be further enhanced, which is preferable.
（外周ベルト）
　図３および図７示すように、外周ベルト３７は、硬貨搬送円盤３２の下部領域の硬貨と接触して、硬貨搬送円盤３２による硬貨の搬送を補助する。外周ベルト３７は、その搬送面が硬貨搬送円盤３２の外周に対向する姿勢にて、硬貨搬送円盤３２の下部領域において硬貨搬送円盤３２に隣接して配置されている。 (Peripheral belt)
As shown in FIGS. 3 and 7, the outer peripheral belt 37 comes in contact with the coin in the lower region of the coin transfer disc 32 to assist the transfer of the coin by the coin transfer disc 32. The outer peripheral belt 37 is disposed adjacent to the coin transport disc 32 in the lower region of the coin transport disc 32 in a posture in which the transport surface faces the outer periphery of the coin transport disc 32.
　本実施形態では外周ベルト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、硬貨搬送円盤３２の近傍では、ベース部材３１の周壁３１ａと硬貨搬送円盤３２との間に、硬貨搬送円盤３２の外周３２ｂに接触する状態で配置されている。硬貨搬送円盤３２が回転すると、外周ベルト３７は、硬貨搬送円盤３２と接触した状態のまま、硬貨搬送円盤３２と共に移動する。 In the present embodiment, the outer peripheral belt 37 is a flat belt and is wound around the three outer peripheral pulleys 37a. The three outer peripheral pulleys 37a are freely rotatable. The outer peripheral belt 37 is disposed between the peripheral wall 31 a of the base member 31 and the coin transport disc 32 in the vicinity of the coin transport disc 32 in a state of being in contact with the outer periphery 32 b of the coin transport disc 32. When the coin transport disc 32 rotates, the outer peripheral belt 37 moves together with the coin transport disc 32 while in contact with the coin transport disc 32.
　そうすると図７に示すように、摩擦搬送部位３２ｃの上の硬貨Ｃ６０は、その外周が外周ベルト３７と接触した状態で、硬貨搬送円盤３２によって搬送される。このとき外周ベルト３７は硬貨搬送円盤３２と同期して走行し、硬貨Ｃ６０と共に硬貨搬送円盤３２の上部領域へと移動する。よって硬貨Ｃ６０の搬送に際して硬貨Ｃ６０と壁面等との摺動が生じず、硬貨Ｃ６０の搬送がスムーズに行われることになる。また別の言い方をすれば、硬貨Ｃ６０は硬貨搬送円盤３２の摩擦搬送部位３２ｃと外周ベルト３７との両方から力を受けて、硬貨搬送円盤３２の上部領域へ搬送される。 Then, as shown in FIG. 7, the coin C <b> 60 on the friction conveyance portion 32 c is conveyed by the coin conveyance disk 32 in a state where the outer periphery thereof is in contact with the outer peripheral belt 37. At this time, the outer peripheral belt 37 travels in synchronization with the coin transport disk 32, and moves to the upper region of the coin transport disk 32 together with the coin C60. Therefore, sliding of the coin C60 and the wall surface or the like does not occur during conveyance of the coin C60, and conveyance of the coin C60 is smoothly performed. In other words, the coin C60 is transported to the upper region of the coin transport disc 32 under the force from both the friction transport portion 32c of the coin transport disc 32 and the outer peripheral belt 37.
　すなわち硬貨繰出装置３０は、外周ベルト３７を有し、外周ベルト３７は、その搬送面が硬貨搬送円盤３２の外周３２ｂに対向する姿勢にて、硬貨搬送円盤３２の下部領域において硬貨搬送円盤３２に隣接して配置され、硬貨搬送円盤３２の回転方向と同じ方向に移動し、摩擦搬送部位３２ｃの上の硬貨と接触して硬貨搬送円盤３２による硬貨の搬送を補助する。なお、外周ベルト３７を上述したベルト３３のように、弾性変形部３３ｂの端部３３ｂ１で硬貨を押圧保持しながら搬送するように構成してもよい。 That is, the coin feeding device 30 has the outer peripheral belt 37, and the outer peripheral belt 37 has the coin transport disk 32 in the lower region of the coin transport disk 32 in a posture in which the transport surface faces the outer periphery 32b of the coin transport disk 32. Adjacent to each other, the coin transport disk 32 moves in the same direction as the rotation direction of the coin transport disk 32, contacts the coins on the friction transport site 32c, and assists the coin transport disk 32 to transport coins. The outer peripheral belt 37 may be configured to be transported while pressing and holding a coin at the end 33b1 of the elastically deformable portion 33b as the belt 33 described above.
（レバー部材）
　図３に示すように、レバー部材３９は、ベルト３３に対して、硬貨搬送円盤３２による硬貨の搬送方向の上流側に配置され、摩擦搬送部位３２ｃの上の硬貨と接触して、硬貨を段差部位３２ｄに向けて移動させる。本実施形態のレバー部材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、硬貨搬送円盤３２の摩擦搬送部位３２ｃの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が硬貨搬送円盤３２の上の硬貨により硬貨搬送円盤３２の外側へ向けて変位すると、バネ３９ｂがレバー部材３９を硬貨搬送円盤３２の内側へ向けて付勢する。 (Lever member)
As shown in FIG. 3, the lever member 39 is disposed on the upstream side of the coin transport disk 32 in the coin transport direction with respect to the belt 33, and contacts the coin on the friction transport site 32 c to step the coin Move toward the site 32d. The lever member 39 according to the present embodiment is a member curved in an arc shape, and one end of the lever member 39 is attached to the base member 31 so as to be rotatable around the shaft 39 a. The other end of the lever member 39 is disposed above the friction transfer portion 32 c of the coin transfer disk 32. A spring 39 b is connected to the lever member 39, and when the lever member 39 is displaced toward the outside of the coin transport disk 32 by the coin on the coin transport disk 32, the spring 39 b moves the lever member 39 to the coin transport disk 32. Energize inward.
　硬貨搬送円盤３２により搬送される硬貨は、遠心力によって、例えば図３に示す硬貨Ｃ３１のように硬貨搬送円盤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によって硬貨搬送円盤３２の内側へ向けて移動され、硬貨搬送円盤３２の段差部位３２ｄに接触する。 The coin transported by the coin transport disk 32 is transported by centrifugal force so as to be positioned near the outer periphery of the coin transport disk 32 as, for example, a coin C31 shown in FIG. 3. When such a coin contacts the lever member 39, the coin member is moved by the lever member 39 toward the inside of the coin transport disk 32, and contacts the step portion 32d of the coin transport disk 32.
　次に、硬貨繰出装置３０で行われる重送硬貨の捌きについて、図１０および図１１を用いて説明する。 Next, the unwinding of double-fed coins performed by the coin feeding device 30 will be described using FIGS. 10 and 11.
　硬貨が硬貨搬送円盤３２によって下部領域から搬送される際、図３に示す硬貨Ｃ３０～Ｃ３２のように１枚ずつ搬送される場合と、図１０に示す硬貨Ｃ９１～Ｃ９７のように、複数枚の硬貨が固まったり重なったりして搬送される場合がある。これは硬貨搬送円盤３２の回転が高速で、遠心力が大きくなる場合に顕著である。 When coins are transported from the lower area by the coin transport disk 32, one sheet is transported one by one like coins C30 to C32 shown in FIG. 3 and a plurality of sheets like coins C91 to C97 shown in FIG. Coins may be transported as they harden or overlap. This is remarkable when the rotation of the coin transport disk 32 is high and the centrifugal force is large.
　図１０に示す硬貨Ｃ９２は硬貨Ｃ９１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する可能性が高い。硬貨Ｃ９４はレバー部材３９と接触し、レバー部材３９によって段差部位３２ｄに向けて移動されている。このときレバー部材３９は、硬貨Ｃ９４に押されて上方に変位している。硬貨Ｃ９５は、レバー部材３９と接触して段差部位３２ｄに向けて移動されるが、硬貨Ｃ９４と重なっていることから段差部位３２ｄに引っ掛からず、重力の作用により下方に落下している。 The coin C92 shown in FIG. 10 is conveyed while being caught by the coin C91, but if it exceeds this position, it is highly likely to fall downward due to the action of gravity. The coin C94 is in contact with the lever member 39 and is moved by the lever member 39 toward the stepped portion 32d. At this time, the lever member 39 is pushed upward by the coin C94. The coin C95 contacts the lever member 39 and is moved toward the stepped portion 32d. However, since the coin C95 is overlapped with the coin C94, the coin C95 is not caught on the stepped portion 32d and drops downward by the action of gravity.
　硬貨Ｃ９６は、段差部位３２ｄに接触した状態でベルト３３に接触し、ベルト３３の下に潜り込んだ状態となっている。一方、硬貨Ｃ９７は硬貨Ｃ９６と重なっていることから、段差部位３２ｄの外周面３２ｅと接触しない状態でベルト３３と接触している。そうすると硬貨Ｃ９７は、ベルト３３の弾性変形部３３ｂを変形させることができず、またベルト３３の下に潜り込むことができず、ベルト３３に押されて下方に落下する。このようにして硬貨繰出装置３０のベルト３３にて重送硬貨の捌きが行われると共に、硬貨搬送円盤３２の径方向（繰出し方向に直角な方向）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繰り出し（硬貨Ｃ９８、Ｃ９９）が実現される。 The coin C96 is in contact with the belt 33 in a state of being in contact with the stepped portion 32d, and is in a state of being under the belt 33. On the other hand, since the coin C97 overlaps with the coin C96, the coin C97 is in contact with the belt 33 without contacting the outer peripheral surface 32e of the stepped portion 32d. Then, the coin C97 can not deform the elastically deforming portion 33b of the belt 33 and can not go under the belt 33, and is pushed by the belt 33 and falls downward. In this manner, the double feed coins are unwound by the belt 33 of the coin feeding device 30, and the coins aligned in the radial direction (direction perpendicular to the feeding direction) of the coin transport disc 32 can also be put in a single row. The feeding (coins C 98 and C 99) to the depositing and conveying unit 20 in a single-row state is realized.
　本実施形態の硬貨入金機１０では、上部搬送部分２０ａに設けられた選別部２４（選別部２４ｂ、２４ｄ、２４ｅ）により選別される硬貨の直径の大きさ（具体的には、１セント硬貨、５セント硬貨、１０セント硬貨の直径の大きさ）は、下部搬送部分２０ｃに設けられた選別部２４（選別部２４ｆ～２４ｈ）により選別されたり開口２４ｉに入ったりする硬貨の直径の大きさ（具体的には、２ユーロ硬貨、１ユーロ硬貨、２セント硬貨、５０セント硬貨、２０セント硬貨の直径の大きさ）よりも小さくなっている。このため、直径が比較的小さな硬貨が折り返し搬送部分２０ｂを経て下部搬送部分２０ｃに送られることが抑制され、このことにより、このような直径が比較的小さな硬貨により折り返し搬送部分２０ｂや下部搬送部分２０ｃでジャム等のトラブルが発生してしまうことを防止することができるようになる。 In the coin depositing machine 10 of the present embodiment, the diameter of the coins sorted by the sorting unit 24 (sorting units 24b, 24d, 24e) provided in the upper conveyance portion 20a (specifically, 1 cent coin, The size of the diameter of the coins which are sorted by the sorting unit 24 (sorting units 24f to 24h) provided in the lower conveyance portion 20c and which enter into the opening 24i (5 cents coin, 10 cents coin diameter size) Specifically, they are smaller than 2 euros, 1 euros, 2 cents, 50 cents, and 20 cents in diameter. For this reason, it is suppressed that a coin with a comparatively small diameter is sent to lower conveyance part 20c via return conveyance part 20b, and, by this, a return conveyance part 20b and a lower conveyance part with such a comparatively small diameter coin In 20c, it is possible to prevent problems such as jamming from occurring.
　また、下部搬送部分２０ｃの第２搬送部分２０ｅに設けられた搬送ベルト２１ｆによる硬貨の搬送速度は、上部搬送部分２０ａに設けられたベルト３３による硬貨の搬送速度と同一となっている。なお、前述したように、第２搬送部分２０ｅに設けられた搬送ベルト２１ｆによる硬貨の搬送速度は、第１搬送部分２０ｄに設けられた搬送ベルト２１ｅによる硬貨の搬送速度よりも大きくなっている。 The coin transport speed by the transport belt 21f provided in the second transport portion 20e of the lower transport portion 20c is the same as the coin transport speed by the belt 33 provided in the upper transport portion 20a. In addition, as mentioned above, the conveyance speed of the coin by the conveyance belt 21f provided in the 2nd conveyance part 20e is larger than the conveyance speed of the coin by the conveyance belt 21e provided in the 1st conveyance part 20d.

That is, for each sorting unit 24a to 24h shown in FIG. 3, for example, when it is known in advance that the number of coins of a specific denomination among the coins to be processed is large, the plurality of sorting units 24 Specific denominations may be assigned.
　上述の実施形態では、ベルト３３の弾性変形部３３ｂの径方向Ｒａの厚さを、本体部３３ａの径方向Ｒａの厚さよりも小さく形成した。ベルト３３の形態としては、以下示すような異なる形態も可能である。なお以下の説明では、上述した実施形態と同様の構成については同じ符号を付し、説明を省略する。 In the above embodiment, the thickness in the radial direction Ra of the elastically deformable portion 33b of the belt 33 is smaller than the thickness in the radial direction Ra of the main body portion 33a. The form of the belt 33 may be different as shown below. In the following description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.
（別実施形態１）
　図１２～図１４に示すように、本実施形態に係るベルト１３３は、ゴム等の弾性部材により環状に構成されており、本体部１３３ａと、本体部１３３ａから幅方向Ｗ（図１３の断面長手方向）に延出した弾性変形部１３３ｂと、を有している。 (Another embodiment 1)
As shown in FIG. 12 to FIG. 14, the belt 133 according to the present embodiment is annularly formed of an elastic member such as rubber, and the width direction W from the main body portion 133 a and the main body portion 133 a And an elastically deformable portion 133 b extending in the
　本体部１３３ａは、断面が径方向Ｒａよりも幅方向Ｗが大きい矩形状に構成されている。図１３～図１４に示すように、本体部１３３ａの内周面には、第１プーリー３４ａの外周面に形成された複数の凹状部３４ａ１と噛み合う複数の凸状部１３３ａ１が形成されている。また、本体部１３３ａの内周面には、幅方向Ｗの一対の凸状部１３３ａ１の間に、第１プーリー３４ａの外周面の中央部分に形成された環状凸部３４ａ２に係合する環状溝１３３ａ２が形成されている。 The main body portion 133a is configured in a rectangular shape whose cross section is larger in the width direction W than the radial direction Ra. As shown in FIGS. 13 to 14, a plurality of convex portions 133a1 meshing with a plurality of concave portions 34a1 formed on the outer peripheral surface of the first pulley 34a are formed on the inner peripheral surface of the main body portion 133a. Further, on the inner peripheral surface of the main body portion 133a, an annular groove engaged with the annular convex portion 34a2 formed in the central portion of the outer peripheral surface of the first pulley 34a between the pair of convex portions 133a1 in the width direction W 133a2 is formed.
　また、図１３に示すように、本実施形態における本体部１３３ａの径方向Ｒａ中央部分には、周方向Ｒｏに伸縮しない樹脂等で構成される芯体１３３ｃが埋設されている。芯体１３３ｃの径方向Ｒａの両側面には、周方向Ｒｏに伸縮可能な伸縮体１３３ｄ（薄手の帆布等）が環状に配置されている。この伸縮体１３３ｄは、径方向Ｒａに変形可能な厚さで構成されている。 Further, as shown in FIG. 13, a core 133 c made of a resin or the like that does not expand and contract in the circumferential direction Ro is embedded in the central portion of the main body portion 133 a in the radial direction Ra in the present embodiment. On both side surfaces of the core body 133c in the radial direction Ra, an expandable body 133d (thin canvas etc.) that can be expanded and contracted in the circumferential direction Ro is annularly disposed. The stretchable body 133 d is configured to have a thickness that can be deformed in the radial direction Ra.
　弾性変形部１３３ｂは、断面が長方形である複数の棒状部位１３３ｅを有しており、ベルト１３３において弾性変形が可能なように構成された部位である。複数の棒状部位１３３ｅは、周方向Ｒｏに沿って等間隔に互いに離間している。弾性変形部１３３ｂは、本体部１３３ａよりも弾性率（変形のしにくさを表す物性値、剪断変形率，引張弾性率および体積弾性率の少なくとも１つ）が小さく構成されている。本実施形態の弾性変形部１３３ｂは、本体部１３３ａと同等の厚さを有しているが、本体部１３３ａには芯体１３３ｃが埋設されていることにより、本体部１３３ａよりも弾性率が小さく構成されている。また、弾性変形部１３３ｂの内周面（本体部１３３ａの側の面）には、本体部１３３ａに設けられた一方の伸縮体１３３ｄと連続する伸縮体１３３ｄが配置されている。この伸縮体１３３ｄによって複数の棒状部位１３３ｅが互いに結合されている。さらに、弾性変形部１３３ｂの一端は、本体部１３３ａの一方の凸状部１３３ａ１まで延びた連結部１３３ｂ２を有する状態で、本体部１３３ａと接続されている。 The elastically deformable portion 133 b has a plurality of rod-like portions 133 e having a rectangular cross section, and is a portion of the belt 133 configured to be elastically deformable. The plurality of rod-like portions 133 e are spaced apart at equal intervals along the circumferential direction Ro. The elastic deformation portion 133b is configured to have a smaller elastic modulus (a physical property value indicating difficulty in deformation, at least one of a shear deformation rate, a tensile elastic modulus, and a bulk elastic modulus) than the main body portion 133a. The elastic deformation portion 133b of this embodiment has a thickness equal to that of the main body portion 133a, but the core 133c is embedded in the main body portion 133a, so that the elastic modulus is smaller than that of the main body portion 133a. It is configured. Further, on the inner peripheral surface (surface on the side of the main body portion 133a) of the elastically deformable portion 133b, an expandable body 133d continuous with one elastic body 133d provided on the main body portion 133a is disposed. The plurality of rod-like portions 133 e are connected to each other by the stretchable body 133 d. Furthermore, one end of the elastically deformable portion 133b is connected to the main body portion 133a in a state of having a connecting portion 133b2 extending to one convex portion 133a1 of the main body portion 133a.
　硬貨搬送円盤３２の上面および搬送路２１ａの搬送路側面２１ｃと、ベルト１３３の端部１３３ｂ１との間の距離Ｄ１は、硬貨繰出装置３０が処理の対象とする処理対象硬貨の最小の厚さより小さい。また、弾性変形部１３３ｂの幅方向Ｗの長さ、すなわち弾性変形部１３３ｂが本体部１３３ａから延出している長さは、硬貨繰出装置３０が処理の対象とする処理対象硬貨の最大の厚さよりも大きい。また、弾性変形部１３３ｂの幅方向Ｗの長さは、径方向Ｒａの厚さよりも大きく構成されており、径方向Ｒａの厚さの５倍以上に設定されている。さらに、弾性変形部１３３ｂは周方向Ｒｏに接続された環状に形成されていることから、ベルト１３３の径方向Ｒａについての弾性変形部１３３ｂの曲げ剛性が、ベルト１３３の周方向Ｒｏ（ベルト１３３の走行方向）についての弾性変形部１３３ｂの曲げ剛性よりも低くなっている。 The distance D1 between the upper surface of the coin transport disk 32 and the transport path side 21c of the transport path 21a and the end 133b1 of the belt 133 is smaller than the minimum thickness of the processing target coin to be processed by the coin feeding device 30 . Further, the length in the width direction W of the elastically deformable portion 133b, that is, the length in which the elastically deformable portion 133b extends from the main body portion 133a, is greater than the maximum thickness of the processing object coin to be processed by the coin feeding device 30. Too big. The length in the width direction W of the elastically deformable portion 133b is larger than the thickness in the radial direction Ra, and is set to five times or more the thickness in the radial direction Ra. Furthermore, since the elastically deformable portion 133 b is formed in an annular shape connected in the circumferential direction Ro, the bending rigidity of the elastically deformable portion 133 b with respect to the radial direction Ra of the belt 133 is the circumferential direction Ro of the belt 133 (the belt 133 It is lower than the bending rigidity of the elastically deformable portion 133b in the traveling direction).
　図１４に示す硬貨Ｃ１４０の状態は、硬貨Ｃ１４０がベルト１３３、詳しくはベルト１３３の弾性変形部１３３ｂを弾性変形させて、ベルト１３３と硬貨搬送円盤３２との間に潜り込んだ状態を示している。このときベルト１３３の弾性変形部１３３ｂが、硬貨Ｃ１４０により、弾性変形部１３３ｂの長手方向の中程で折れ曲がり、第１プーリー３４ａの内側に向かって弾性変形した状態となっている。そして硬貨Ｃ１４０は、弾性変形した弾性変形部１３３ｂの端部１３３ｂ１の側面によって、摩擦搬送部位１３２ｃの上面に向けて押圧保持されている。この硬貨Ｃ１４０は、弾性変形部１３３ｂの弾性復元作用により、段差部位３２ｄの外周面３２ｅに寄せられて当接している。 The state of the coin C140 shown in FIG. 14 is a state in which the coin C140 elastically deforms the belt 133, and more specifically, the elastic deformation portion 133b of the belt 133, and sinks between the belt 133 and the coin transport disk 32. At this time, the elastically deformable portion 133b of the belt 133 is bent in the middle in the longitudinal direction of the elastically deformable portion 133b by the coin C140, and elastically deformed inward of the first pulley 34a. The coin C140 is pressed and held by the side surface of the end portion 133b1 of the elastically deformed elastically deformable portion 133b toward the upper surface of the friction transfer portion 132c. The coin C140 is brought close to and in contact with the outer peripheral surface 32e of the stepped portion 32d by the elastic restoring action of the elastic deformation portion 133b.
　図１４に示す硬貨Ｃ１４１の状態は、硬貨Ｃ１４０よりも薄く小さい硬貨がベルト１３３とベース部材３１（搬送路２１ａ）との間に潜り込んだ状態を示している。このとき、硬貨Ｃ１４１は、弾性変形した弾性変形部１３３ｂによって、ベース部材３１（搬送路２１ａ）に向けて押圧されている。そして硬貨Ｃ１４１は、弾性変形した弾性変形部１３３ｂの端部１３３ｂ１の側面によって、摩擦搬送部位３２ｃの上面に向けて押圧保持されている。この硬貨Ｃ１４１は、弾性変形部１３３ｂの弾性復元作用により、案内部材３８の内面３８ａに寄せられて当接している。 The state of the coin C141 shown in FIG. 14 shows a state in which a coin thinner and smaller than the coin C140 is embedded between the belt 133 and the base member 31 (conveying path 21a). At this time, the coin C141 is pressed toward the base member 31 (the transport path 21a) by the elastically deformable portion 133b. The coin C141 is pressed and held by the side surface of the end portion 133b1 of the elastically deformed elastically deformable portion 133b toward the upper surface of the friction transfer portion 32c. The coin C141 is brought close to and in contact with the inner surface 38a of the guide member 38 by the elastic restoring action of the elastically deformable portion 133b.
　図１４に示す硬貨Ｃ１４２の状態は、硬貨Ｃ１４０よりも厚く大きい硬貨がベルト１３３とベース部材３１（搬送路２１ａ）との間に潜り込んだ状態を示している。このとき、硬貨Ｃ１４２は、弾性変形した弾性変形部１３３ｂによって、ベース部材３１に向けて押圧されている。そして硬貨Ｃ１４２は、弾性変形した弾性変形部１３３ｂによって、ベース部材３１（搬送路２１ａの搬送路側面２１ｃ）に向けて押圧されている。この硬貨Ｃ１４２は、弾性変形部１３３ｂの弾性復元作用により、搬送路２１ａの搬送路底面２１ｄに寄せられて当接している。このように、径方向Ｒａに弾性変形する弾性変形部１３３ｂの弾性復元作用により、摩擦搬送部位３２ｃ又は搬送路２１ａの一方側に形成された段差部位３２ｄの外周面３２ｅ，案内部材３８の内面３８ａ又は搬送路側面２１ｃに硬貨を寄せつつ搬送するので、硬貨を一列に整列させた状態で搬送することができる。 The state of the coin C142 shown in FIG. 14 shows a state in which a coin thicker and larger than the coin C140 is embedded between the belt 133 and the base member 31 (conveying path 21a). At this time, the coin C142 is pressed toward the base member 31 by the elastically deformable portion 133b. Then, the coin C142 is pressed toward the base member 31 (the conveyance path side surface 21c of the conveyance path 21a) by the elastically deformed elastically deformable portion 133b. The coin C142 is brought close to and in contact with the bottom surface 21d of the conveyance path 21a by the elastic restoring action of the elastic deformation portion 133b. Thus, the outer peripheral surface 32e of the stepped portion 32d formed on one side of the friction conveyance portion 32c or the conveyance path 21a by the elastic restoring action of the elastic deformation portion 133b elastically deformed in the radial direction Ra, the inner surface 38a of the guide member 38 Alternatively, since the coins are transported while being brought close to the transport path side surface 21c, the coins can be transported in a line.
　ベルト１３３の弾性変形部１３３ｂが硬貨Ｃ１４２によって変形している領域の長さ（ベルト１３３の周方向Ｒｏに沿った長さ）は、硬貨Ｃ１４１によって変形している領域の長さよりも大きい。弾性変形部１３３ｂの硬貨Ｃ１４２による径方向Ｒａ内方への変形量（例えば、折れ曲がった部分の長さ）は、硬貨Ｃ１４１による変形量よりも大きい。このように、ベルト１３３（弾性変形部１３３ｂ）は、接触する硬貨の大きさおよび厚さに応じて弾性変形する。 The length of the area (length along the circumferential direction Ro of the belt 133) in which the elastic deformation portion 133b of the belt 133 is deformed by the coin C142 is larger than the length of the area deformed by the coin C141. The amount of deformation (for example, the length of the bent portion) inward in the radial direction Ra by the coin C142 of the elastically deformable portion 133b is larger than the amount of deformation by the coin C141. Thus, the belt 133 (elastically deformable portion 133b) is elastically deformed in accordance with the size and thickness of the contacting coin.
　本実施形態においても上述した実施形態と同様に、弾性率の小さい弾性変形部１３３ｂの端部１３３ｂ１を径方向Ｒａに変形させることにより硬貨Ｃ１４０、Ｃ１４１、Ｃ１４２を保持するので、全体的にベルト１３３が撓むことなく、弾性変形部１３３ｂの端部１３３ｂ１に保持された硬貨Ｃ１４０、Ｃ１４１、Ｃ１４２と隣接する部位には、弾性変形部１３３ｂの変形により生じる空間を最小限とすることが可能となる。よって、硬貨搬送円盤３２から複数の硬貨Ｃ１４０、Ｃ１４１、Ｃ１４２が連なって移動してきた場合でも、これらの硬貨Ｃ１４０、Ｃ１４１、Ｃ１４２を搬送路２１ａで円滑に搬送することができる。 Also in this embodiment, since the coins C140, C141, and C142 are held by deforming the end portion 133b1 of the elastic deformation portion 133b having a small elastic modulus in the radial direction Ra, as in the above-described embodiment, the belt 133 as a whole. In the region adjacent to the coins C140, C141, and C142 held at the end 133b1 of the elastically deformable portion 133b, the space generated by the deformation of the elastically deformable portion 133b can be minimized without bending. . Therefore, even when a plurality of coins C140, C141, and C142 move in a row from the coin transport disk 32, these coins C140, C141, and C142 can be smoothly transported through the transport path 21a.
　また、本実施形態では、弾性変形部１３３ｂが複数の棒状部位１３３ｅを有しているので、仮に硬貨とベルト１３３との間で滑りが生じたとしても、棒状部位１３３ｅのエッジによって該移動を阻止することができる。さらに、本実施形態では、これら棒状部位１３３ｅを周方向Ｒｏに伸縮可能な伸縮体１３３ｄにより互いに結合しているので、弾性変形部１３３ｂが捻れ変形した場合でも、伸縮体１３３ｄが捻れ変形に追従する。つまり、互いに離間した棒状部位１３３ｅが捻れ変形に追従する伸縮体１３３ｄによって結合されているので、棒状部位１３３ｅの根元部位が捻れ変形することによって亀裂が発生するといった不都合を防止することができ、ベルト１３３によって確実に硬貨を搬送することができる。 Further, in the present embodiment, since the elastically deformable portion 133b has the plurality of rod-like portions 133e, even if slippage occurs between the coin and the belt 133, the movement is blocked by the edge of the rod-like portion 133e. can do. Furthermore, in the present embodiment, since the bar-like portions 133e are connected to each other by the stretchable body 133d which can be stretched in the circumferential direction Ro, the stretchable body 133d follows the twisting deformation even when the elastically deformable portion 133b is twisted and deformed. . That is, since the bar-like portions 133e separated from each other are connected by the stretchable body 133d following the twisting deformation, it is possible to prevent the problem that the crack is generated due to the twisting deformation of the root portion of the bar-like portions 133e, and the belt The coins can be reliably transported by means of 133.
（別実施形態２）
　図１５～図１６に示すように、本実施形態に係るベルト２３３は、ゴム等の弾性部材により環状に構成されており、本体部２３３ａと、本体部２３３ａから幅方向Ｗ（図１６の断面長手方向）に延出した弾性変形部２３３ｂと、を有している。本実施形態のベルト２３３は、本体部２３３ａと弾性変形部２３３ｂとが同一の寸法を有している。なお、本体部２３３ａに上述した実施形態における芯体３３ｃ，１３３ｃを設けて、弾性変形部２３３ｂの弾性率を本体部２３３ａの弾性率よりも小さく構成することが好ましい。 (Another embodiment 2)
As shown in FIGS. 15 to 16, the belt 233 according to the present embodiment is annularly formed of an elastic member such as rubber, and the main body 233a and the main body 233a in the width direction W (cross section in FIG. And an elastically deformable portion 233 b extending in the In the belt 233 of the present embodiment, the main body portion 233a and the elastically deformable portion 233b have the same dimensions. In addition, it is preferable to provide the cores 33c and 133c in the embodiment described above in the main body portion 233a, and to configure the elastic modulus of the elastic deformation portion 233b to be smaller than the elastic modulus of the main body portion 233a.
　本実施形態における本体部２３３ａは、ベルト駆動機構３４の一部を構成する断面コの字状の支持部材３４ｆに嵌合されている。これによって、弾性変形部２３３ｂを弾性変形させて硬貨を押圧保持することが可能となる。 The main body 233a in the present embodiment is fitted to a support member 34f having a U-shaped cross section, which constitutes a part of the belt drive mechanism 34. By this, it becomes possible to elastically deform the elastically deforming portion 233 b and press and hold the coin.
