姿勢矯正部４６０は、搬入検出部４５０の搬送方向下流側に位置し、硬貨受容部４２４に受容された硬貨に接触して硬貨受容部４２４における硬貨の姿勢を矯正する。姿勢矯正部４６０は、搬送ディスク４２０の半径方向において硬貨受容部４２４よりも外方に設けられ、軸４６１周りに回動可能なレバ部材４６２を有する。 (Posture Correction Department)
The posture correction unit 460 is located on the downstream side in the transport direction of the carry-in detection unit 450 and contacts the coin received by the coin receiving unit 424 to correct the posture of the coin in the coin receiving unit 424. The posture correction unit 460 includes a lever member 462 that is provided outward from the coin receiving unit 424 in the radial direction of the transport disk 420 and that can rotate about a shaft 461.

レバ部材４６２は、硬貨の側面に接触して硬貨を硬貨受容部４２４側へ向けて押圧する押圧部材である。レバ部材４６２は、不図示のスプリングによって図１の矢印方向に押圧されることで、硬貨受容部４２４に受容された硬貨に接触する。これにより、直径が異なる硬貨が硬貨受容部４２４に受容されても、硬貨に接触可能である。レバ部材４６２は、搬送ディスク４２０の回転中に、硬貨に接触して硬貨を硬貨受容部４２４に奥側に寄らせる。そして、レバ部材４６２は、硬貨受容部４２４と共に硬貨を挟持することで、硬貨受容部４２４における硬貨の挙動を安定させる。 The lever member 462 is a pressing member that contacts the side surface of the coin and presses the coin toward the coin receiving portion 424 side. The lever member 462 is pressed in the direction of the arrow in FIG. 1 by a spring (not shown), thereby contacting the coin received by the coin receiving portion 424. Thereby, even if the coin from which a diameter differs is received by the coin receiving part 424, it can contact a coin. The lever member 462 comes into contact with the coin while the conveyance disk 420 is rotating, and causes the coin to approach the coin receiving portion 424 on the back side. And the lever member 462 stabilizes the behavior of the coin in the coin receiving part 424 by pinching a coin with the coin receiving part 424.

レバ部材４６２には、レバ部材４６２の回動を規制する規制部（不図示）が設けられている。この規制部によって、レバ部材４６２は、硬貨受容部４２４に受容された硬貨に対して接触可能であるのに対して、搬送ディスク４２０には接触しない。 The lever member 462 is provided with a restricting portion (not shown) that restricts the rotation of the lever member 462. By this restricting portion, the lever member 462 can contact the coin received by the coin receiving portion 424, but does not contact the transport disk 420.

レバ部材４６２の、硬貨受容部４２４と共に硬貨を挟持（接触）する部分に、レバ凹部４６４が形成されている。搬送ディスク４２０のディスク凹部４２５も、硬貨を挟持する部分に形成されている。このため、図４に示すように、レバ凹部４６４とディスク凹部４２５は、レバ部材４６２と硬貨受容部４２４が硬貨を挟持した際に、硬貨に対するレバ部材４６２及び硬貨受容部４２４の境界を成す機能を有する。図４は、硬貨、レバ凹部４６４、及びディスク凹部４２５の位置関係を説明するための図である。 A lever recess 464 is formed in a portion of the lever member 462 that holds (contacts) the coin together with the coin receiving portion 424. The disk recess 425 of the transport disk 420 is also formed in a portion that holds coins. Therefore, as shown in FIG. 4, the lever recess 464 and the disk recess 425 form a boundary between the lever member 462 and the coin receiving portion 424 for the coin when the lever member 462 and the coin receiving portion 424 hold the coin. Have FIG. 4 is a diagram for explaining the positional relationship between coins, lever recesses 464, and disk recesses 425. FIG.

なお、レバ凹部４６４の幅は、ディスク凹部４２５の幅よりも小さく形成されても良い。これは、ディスク凹部４２５は、様々な直径の硬貨を硬貨受容部４２４で安定した姿勢に保つには、凹部の幅を大きくする必要があるのに対して、レバ部材４６２は硬貨に合わせて回動するので、レバ凹部４６４の幅が小さくても硬貨を挟持できるからである。 The width of the lever recess 464 may be smaller than the width of the disk recess 425. This is because the disk recess 425 needs to increase the width of the recess in order to keep coins of various diameters in a stable posture by the coin receiving portion 424, whereas the lever member 462 rotates according to the coin. This is because the coin can be held even if the lever recess 464 is small in width.

（識別部）
識別部４７０は、搬送ディスク４２０により搬送される硬貨の真偽、金種等を識別する。識別部４７０は、搬送ディスク４２０の回転方向において、搬入検出部４５０の下流側に位置する。識別部４７０は、光学センサ４７２と、磁気センサ４７４、４７６とを有する。 (Identification part)
The identification unit 470 identifies the authenticity, denomination, etc. of the coins conveyed by the conveyance disk 420. The identification unit 470 is located downstream of the carry-in detection unit 450 in the rotation direction of the transport disk 420. The identification unit 470 includes an optical sensor 472 and magnetic sensors 474 and 476.

光学センサ４７２は、搬送ディスク４２０の回転中に、硬貨受容部４２４に受容された硬貨を検出する。光学センサ４７２は、光を発する発光部の一例である光源４７２ａと、光源４７２ａが発した光を受光する受光部の一例であるラインセンサ４７２ｂとを有する。光源４７２ａとラインセンサ４７２は、レバ部材４６２を挟んで互いに対向するように配置されている。光源４７２ａは鉛直方向においてレバ部材４６２の上方に位置し、ラインセンサ４７２ｂはレバ部材４６２の下方に位置する。 The optical sensor 472 detects coins received by the coin receiving unit 424 while the transport disk 420 is rotating. The optical sensor 472 includes a light source 472a that is an example of a light emitting unit that emits light, and a line sensor 472b that is an example of a light receiving unit that receives light emitted from the light source 472a. The light source 472a and the line sensor 472 are disposed so as to face each other with the lever member 462 interposed therebetween. The light source 472a is positioned above the lever member 462 in the vertical direction, and the line sensor 472b is positioned below the lever member 462.

光学センサ４７２は、搬送ディスク４２０の回転中に、レバ部材４６２と硬貨受容部４２４によって挟まれた状態の硬貨の直径を取得する。ここで、レバ部材４６２は、光学センサ４７２が検出する際に硬貨の姿勢を矯正する。これにより、光学センサ４７２による硬貨の直径の測定中に硬貨の挙動が安定するので、硬貨の直径を高精度に測定できる。 The optical sensor 472 acquires the diameter of the coin sandwiched between the lever member 462 and the coin receiving portion 424 while the transport disk 420 is rotating. Here, the lever member 462 corrects the posture of the coin when the optical sensor 472 detects it. Thereby, since the behavior of a coin is stabilized during the measurement of the diameter of the coin by the optical sensor 472, the diameter of the coin can be measured with high accuracy.

光学センサ４７２は、硬貨、レバ部材４６２のレバ凹部４６４、及び硬貨受容部４２４のディスク凹部４２５を検出することで、硬貨の直径を取得する。これにより、光学センサ４７２は、硬貨に対するレバ部材４６２及び硬貨受容部４２４の境界を容易に検出できるので、硬貨の直径をより高精度に測定できる。なお、光学センサ４７２は、搬送ディスク４２０の半径方向において、硬貨、レバ凹部４６４、及びディスク凹部４２５が一列に並んだ際に、硬貨、レバ凹部４６４、及びディスク凹部４２５を同時に検出する。これにより、硬貨に対するレバ部材４６２及び硬貨受容部４２４の境界を容易に検出できるので、硬貨の直径を高精度かつ容易に測定できる。 The optical sensor 472 acquires the diameter of the coin by detecting the coin, the lever recess 464 of the lever member 462, and the disk recess 425 of the coin receiving portion 424. Thereby, since the optical sensor 472 can easily detect the boundary between the lever member 462 and the coin receiving portion 424 with respect to the coin, the diameter of the coin can be measured with higher accuracy. The optical sensor 472 simultaneously detects the coin, the lever recess 464, and the disc recess 425 when the coin, the lever recess 464, and the disc recess 425 are arranged in a line in the radial direction of the transport disk 420. Thereby, since the boundary of the lever member 462 and the coin receiving part 424 with respect to the coin can be easily detected, the diameter of the coin can be measured with high accuracy and easily.

磁気センサ４７４、４７６は、光学センサ４７２の搬送方向下流側に位置し、硬貨受容部４２４に受容されて搬送中の硬貨を検出する。 The magnetic sensors 474 and 476 are located on the downstream side of the optical sensor 472 in the transport direction, and are received by the coin receiving unit 424 to detect the coins being transported.

光学センサ４７２、磁気センサ４７４、４７６の検出結果に基づいて、硬貨の各種の特性値が取得される。取得された特性値に基づいて、硬貨の真偽、金種等が識別される。なお、上記では、硬貨の搬送方向に沿って光学センサ、磁気センサの順に配置させているが、これに限定されず、搬送方向に沿って磁気センサ、光学センサの順に配置させても良い。 Based on the detection results of the optical sensor 472 and the magnetic sensors 474 and 476, various characteristic values of the coin are acquired. Based on the acquired characteristic value, the true / false of the coin, the denomination, etc. are identified. In the above description, the optical sensor and the magnetic sensor are arranged in this order along the coin conveyance direction. However, the present invention is not limited to this, and the magnetic sensor and the optical sensor may be arranged in this order along the conveyance direction.

（リジェクト硬貨排出口）
リジェクト硬貨排出口４８０は、識別部４７０の搬送方向下流側において、選別ハウジング４１０の底面４１２に形成された排出口である。リジェクト硬貨排出口４８０は、識別部４７０で偽硬貨や外国硬貨等と識別されたリジェクト硬貨（硬貨受容部４２４に受容された硬貨）を落下させて排出する。リジェクト硬貨排出口４８０には、リジェクト硬貨がリジェクト硬貨排出口４８０に搬送された時に開動作する開閉シャッタ（不図示）が設けられている。 (Reject coin outlet)
The reject coin discharge port 480 is a discharge port formed in the bottom surface 412 of the sorting housing 410 on the downstream side in the transport direction of the identification unit 470. The reject coin discharge port 480 drops and discharges reject coins (coins received by the coin receiving unit 424) that are identified by the identifying unit 470 as fake coins, foreign coins, or the like. The reject coin discharge port 480 is provided with an open / close shutter (not shown) that opens when the reject coin is conveyed to the reject coin discharge port 480.

（正常硬貨排出口）
正常硬貨排出口４８４は、リジェクト硬貨排出口４８０の搬送方向下流側において、選別ハウジング４１０の底面４１２に形成された排出口である。正常硬貨排出口４８４は、識別部４７０で真性硬貨と識別された各金種の正常硬貨（硬貨受容部４２４に受容された硬貨）を落下させて排出する。 (Normal coin outlet)
The normal coin discharge port 484 is a discharge port formed in the bottom surface 412 of the sorting housing 410 on the downstream side in the transport direction of the reject coin discharge port 480. The normal coin discharge port 484 drops and discharges the normal coins (coins received by the coin receiving unit 424) of each denomination identified as genuine coins by the identifying unit 470.

硬貨処理装置１００は、硬貨処理装置１００の全体動作を制御するための制御ユニット（不図示）を有する。制御ユニットは、上述したユニットの各構成要素の動作を制御する制御部（不図示）と、制御部が実行するプログラムや各種のデータを記憶する記憶部（不図示）と、を有する。 The coin processing device 100 has a control unit (not shown) for controlling the overall operation of the coin processing device 100. The control unit includes a control unit (not shown) that controls the operation of each component of the unit described above, and a storage unit (not shown) that stores programs executed by the control unit and various data.

（１−２．硬貨処理装置の動作）
次に、上述した構成を有する硬貨処理装置１００の動作例について説明する。なお、硬貨処理装置１００の動作は、制御ユニットの制御部によって実行される。すなわち、制御部は、記憶部に記憶されたプログラムを実行することで、下記に説明する動作を実行する。 (1-2. Operation of coin processing device)
Next, an operation example of the coin processing apparatus 100 having the above-described configuration will be described. In addition, operation | movement of the coin processing apparatus 100 is performed by the control part of a control unit. That is, a control part performs the operation | movement demonstrated below by running the program memorize | stored in the memory | storage part.

硬貨繰り出しユニット２００の硬貨受領部２１０に硬貨が一括して投入されると、投入された硬貨は回転円盤２３０上に集積される。その後、回転円盤２３０が円盤モータ２４２によって回転すると、回転円盤２３０上の硬貨は、回転による遠心力を受けて収容部２２０の内周面に沿って移動し、放出口２２２より硬貨通路３１０へ一枚ずつ押し出される。 When coins are collectively input into the coin receiving unit 210 of the coin payout unit 200, the inserted coins are accumulated on the rotating disk 230. Thereafter, when the rotating disk 230 is rotated by the disk motor 242, the coins on the rotating disk 230 receive a centrifugal force due to the rotation and move along the inner peripheral surface of the accommodating portion 220, so Extruded one by one.

押し出された硬貨は、硬貨搬送ユニット３００の搬送ローラ３２０が停止中は硬貨通路３１０上に滞留し、搬送ローラ３２０の回転中は挟持されて搬送される。搬送中の硬貨が検出センサ３４０に検出されると、搬送ローラ３２０は、回転が停止して硬貨を挟持した状態を維持する。 The pushed-out coins stay on the coin passage 310 when the transport roller 320 of the coin transport unit 300 is stopped, and are held and transported while the transport roller 320 is rotating. When the coin being transported is detected by the detection sensor 340, the transport roller 320 stops rotating and maintains a state where the coin is clamped.

一方、硬貨選別ユニット４００の搬送ディスク４２０は、ディスクモータ４３２によって回転し、位置検出部４４０によって硬貨受容部４２４が搬入口４１５に対向すると検出されると、一旦停止する。すなわち、位置検出部４４０の出力が「ＯＮ」から「ＯＦＦ」に出力が切り替わると、搬送ディスク４２０の回転が一時停止する。 On the other hand, the conveyance disc 420 of the coin sorting unit 400 is rotated by the disc motor 432 and stops once when the position detection unit 440 detects that the coin receiving unit 424 faces the carry-in port 415. That is, when the output of the position detection unit 440 is switched from “ON” to “OFF”, the rotation of the transport disk 420 is temporarily stopped.

検出センサ３４０は位置検出部４４０と同期をとっており、搬送ディスク４２０が一時停止した際に搬送ローラ３２０が回転することで、搬送ローラ３２０に挟持された硬貨が搬入口４１５を通過して硬貨受容部４２４に搬送される。なお、搬送ローラ３２０による硬貨の搬入方向は、搬送ディスク４２０の回転中心より搬送方向の前方側に位置するように設定されているので、搬送される硬貨は硬貨受容部４２４に対して斜めに進入する。硬貨受容部４２４に搬入された硬貨が搬入検出部４５０によって検出されると、搬送ローラ３２０の回転が停止する。 The detection sensor 340 is synchronized with the position detection unit 440, and when the conveyance disk 420 is temporarily stopped, the conveyance roller 320 rotates, so that the coins sandwiched between the conveyance rollers 320 pass through the carry-in entrance 415 and the coins It is conveyed to the receiving part 424. In addition, since the carry-in direction of the coin by the carrying roller 320 is set so as to be located on the front side in the carrying direction from the rotation center of the carrying disk 420, the coin to be carried enters obliquely with respect to the coin receiving portion 424. To do. When the coins carried into the coin receiving unit 424 are detected by the carry-in detection unit 450, the rotation of the carry roller 320 is stopped.

搬送ディスク４２０は、硬貨が硬貨受容部４２４に搬送された後（所定時間停止した後）に、再度回転を行う。すなわち、搬送ディスク４２０は、間欠回転を行う。そして、上記の動作を連続的に行うことで、投入された硬貨が硬貨受容部４２４に順次搬送される。 The transport disk 420 rotates again after the coin is transported to the coin receiving unit 424 (after being stopped for a predetermined time). That is, the transport disk 420 performs intermittent rotation. The inserted coins are sequentially conveyed to the coin receiving unit 424 by continuously performing the above operation.

硬貨受容部４２４に硬貨が搬送された後に搬送ディスク４２０が更に間欠回転すると、硬貨は、選別ハウジング４１０の側壁４１４に沿って選別ハウジング４１０内の搬送方向に搬送される。なお、搬送ローラ３２０により硬貨が硬貨受容部４２４に斜めに進入しており、搬送ディスク４２０が搬送ローラ３２０から逃げる方向に回転するので、搬送ディスク４２０の回転に伴う硬貨のロックを防止できる。 When the transport disk 420 is further intermittently rotated after the coin is transported to the coin receiving portion 424, the coin is transported along the side wall 414 of the sorting housing 410 in the transporting direction in the sorting housing 410. In addition, since the coin has entered the coin receiving portion 424 obliquely by the transport roller 320 and the transport disk 420 rotates in a direction to escape from the transport roller 320, the coin can be prevented from being locked due to the rotation of the transport disk 420.

硬貨受容部４２４に受容された硬貨は、搬送ディスク４２０の間欠回転（間欠搬送）中に、識別部４７０（光学センサ４７２、磁気センサ４７４、４７６）を通過する。 The coins received by the coin receiving unit 424 pass through the identification unit 470 (optical sensor 472, magnetic sensors 474, 476) during intermittent rotation (intermittent conveyance) of the conveyance disk 420.

図５は、硬貨が光学センサ４７２を通過する際の姿勢の矯正を説明するための図である。一の硬貨受容部４２４に受容された硬貨Ｃが図５（ａ）に示すように光学センサ４７２を通過する前に、硬貨Ｃは、図５（ｂ）に示すようにレバ部材４６２に接触する。その後、硬貨Ｃは、レバ部材４６２に押圧されて、図５（ｃ）に示すように硬貨受容部４２４の奥側に寄せられる。すなわち、硬貨Ｃの姿勢が矯正される。 FIG. 5 is a view for explaining posture correction when a coin passes through the optical sensor 472. Before the coin C received by one coin receiving part 424 passes through the optical sensor 472 as shown in FIG. 5A, the coin C contacts the lever member 462 as shown in FIG. 5B. . Thereafter, the coin C is pressed by the lever member 462 and brought closer to the back side of the coin receiving portion 424 as shown in FIG. That is, the posture of the coin C is corrected.

そして、硬貨Ｃが硬貨受容部４２４の奥側に完全に寄せられた状態で搬送ディスク４２０が更に回転すると、硬貨Ｃは、図５（ｄ）に示すようにレバ部材４６２と硬貨受容部４２４に挟持された状態で搬送され、光学センサ４７２を通過する。硬貨Ｃがレバ部材４６２と硬貨受容部４２４に挟持されているので、光学センサ４７２を通過する硬貨Ｃの挙動は安定する。 Then, when the conveyance disk 420 further rotates in a state where the coin C is completely moved to the back side of the coin receiving portion 424, the coin C is moved to the lever member 462 and the coin receiving portion 424 as shown in FIG. It is transported in a sandwiched state and passes through the optical sensor 472. Since the coin C is sandwiched between the lever member 462 and the coin receiving portion 424, the behavior of the coin C passing through the optical sensor 472 is stabilized.

硬貨が光学センサ４２７を通過時、光学センサ４２７は、硬貨だけでなく、レバ部材４６２のレバ凹部４６４と、硬貨受容部４２４のディスク凹部４２５とを検出する。これにより、硬貨に対するレバ部材４６２及び硬貨受容部４２４の境界を判別できるので、硬貨の直径が正確に測定される。 When the coin passes through the optical sensor 427, the optical sensor 427 detects not only the coin but also the lever recess 464 of the lever member 462 and the disk recess 425 of the coin receiving portion 424. Thereby, since the boundary of the lever member 462 and the coin receiving part 424 with respect to a coin can be discriminate | determined, the diameter of a coin is measured correctly.

搬送ディスク４２０の間欠搬送１回につき、識別部４７０の各センサは、一つの硬貨受容部４２４に受容された硬貨の各種特性値を取得する。そして、各センサのセンサ取得値を用いて、硬貨の真偽、金種等が判別される。すなわち、リジェクト硬貨と、真性硬貨に選別される。 For each intermittent conveyance of the conveyance disk 420, each sensor of the identification unit 470 acquires various characteristic values of the coins received by one coin reception unit 424. And the authenticity of a coin, a money type, etc. are discriminate | determined using the sensor acquisition value of each sensor. That is, it is sorted into reject coins and genuine coins.

その後、識別部４７０による判別結果に基づいて、リジェクト硬貨は、リジェクト硬貨排出口４８０から排出され、真性硬貨は、正常硬貨排出口４８４から排出される。投入された全ての硬貨が排出されると、本動作は終了する。 Thereafter, based on the determination result by the identification unit 470, the reject coin is discharged from the reject coin discharge port 480 and the genuine coin is discharged from the normal coin discharge port 484. When all the inserted coins are discharged, this operation ends.

第１の実施形態においては、レバ部材４６２が、硬貨受容部４２４に受容された硬貨の姿勢を矯正し、光学センサ４７２が、硬貨と、硬貨を挟持するレバ部材４６２及び硬貨受容部４２４の凹部（レバ凹部４６４、及びディスク凹部４２５）とを検出して、硬貨の直径を取得する。かかる構成によれば、レバ部材４６２によって硬貨受容部４２４での硬貨の挙動が安定し、硬貨に対するレバ部材４６２及び硬貨受容部４２４の境界が明確になるので、硬貨の直径を高精度に検出できる。 In the first embodiment, the lever member 462 corrects the posture of the coin received in the coin receiving portion 424, and the optical sensor 472 is a concave portion of the coin and the lever member 462 that holds the coin and the coin receiving portion 424. (Lever recess 464 and disc recess 425) are detected, and the diameter of the coin is acquired. According to this configuration, the lever member 462 stabilizes the behavior of the coin in the coin receiving portion 424, and the boundary between the lever member 462 and the coin receiving portion 424 with respect to the coin becomes clear, so that the diameter of the coin can be detected with high accuracy. .

なお、上記では、レバ部材４６２及び硬貨受容部４２４のそれぞれに、凹部（レバ凹部４６４、ディスク凹部４２５）を設けることとしたが、これに限定されない。例えば、レバ部材４６２及び硬貨受容部４２４のいずれか一方のみに凹部を設けることとしても良い。このような凹部を設けることで、硬貨の直径を精度良く測定できる。 In the above description, the recesses (the lever recess 464 and the disk recess 425) are provided in each of the lever member 462 and the coin receiving portion 424. However, the present invention is not limited to this. For example, it is good also as providing a recessed part only in any one of the lever member 462 and the coin receiving part 424. FIG. By providing such a recess, the diameter of the coin can be accurately measured.

また、上記では、硬貨の姿勢を矯正する押圧部材は、軸を中心に回動可能なレバ部材４６２であることとしたが、これに限定されない。例えば、押圧部材は、直進移動可能な板状部材であり、板状部材がスプリング等で付勢されて硬貨を押圧しても良い。 In the above description, the pressing member that corrects the posture of the coin is the lever member 462 that can rotate around the axis, but is not limited thereto. For example, the pressing member is a plate-like member that can move linearly, and the plate-like member may be biased by a spring or the like to press the coin.

＜２．第２の実施形態＞
図６、図７を参照しながら、第２の実施形態に係る硬貨処理装置１００の構成について説明する。図６は、第２の実施形態に係る硬貨処理装置１００を示す概略平面図である。図７は、図６のＢ−Ｂ断面図である。 <2. Second Embodiment>
The configuration of the coin processing apparatus 100 according to the second embodiment will be described with reference to FIGS. 6 and 7. FIG. 6 is a schematic plan view showing the coin processing apparatus 100 according to the second embodiment. 7 is a cross-sectional view taken along line BB in FIG.

第２の実施形態の姿勢矯正部材の構成は、第１の実施形態の姿勢矯正部材４６０の構成と異なる。以下では、主に、第２の実施形態の姿勢矯正部の構成について説明する。なお、第２の実施形態の姿勢矯正部以外の構成は、第１の実施形態と同様であるので、説明を省略する。 The configuration of the posture correction member of the second embodiment is different from the configuration of the posture correction member 460 of the first embodiment. Below, the structure of the attitude | position correction | amendment part of 2nd Embodiment is mainly demonstrated. In addition, since structures other than the attitude | position correction | amendment part of 2nd Embodiment are the same as that of 1st Embodiment, description is abbreviate | omitted.

第１の実施形態においては、姿勢矯正部４６０のレバ部材４６２が、硬貨の側面に接触して、硬貨を硬貨受容部４２４に寄せることで、光学センサ４７２が硬貨を検出する際の硬貨の姿勢を矯正することとした。これに対して、第２の実施形態に係る姿勢矯正部５６０は、図６及び図７に示すように、搬送ディスク４２０の上方から硬貨の上面に接触して硬貨を下方へ押圧する押圧部材５６２を有する。 In 1st Embodiment, the lever member 462 of the attitude | position correction | amendment part 460 contacts the side surface of a coin, a coin is approached to the coin receiving part 424, and the attitude | position of the coin when the optical sensor 472 detects a coin It was decided to correct. On the other hand, as shown in FIGS. 6 and 7, the posture correcting unit 560 according to the second embodiment is in contact with the upper surface of the coin from above the transport disk 420 and presses the coin downward. Have

押圧部材５６２は、断面が台形形状を成すように形成され、底面５６３が硬貨の上面に接触する。また、押圧部材５６２は、軸５６４に回動可能に支持され、スプリング（不図示）によって硬貨側に押圧される。これにより、厚みが異なる硬貨であっても、押圧部材５６２が硬貨に接触することで、硬貨の変動を抑制できる。 The pressing member 562 is formed so that the cross section has a trapezoidal shape, and the bottom surface 563 is in contact with the upper surface of the coin. The pressing member 562 is rotatably supported by the shaft 564 and is pressed to the coin side by a spring (not shown). Thereby, even if it is a coin from which thickness differs, the fluctuation | variation of a coin can be suppressed because the press member 562 contacts a coin.

押圧部材５６２は、光学センサ４７２の光源４７２ａとラインセンサ４７２ｂの間に位置する。このため、押圧部材５６２は、光学センサ４７２が検出する際に、硬貨を押圧して硬貨の姿勢を矯正する。この結果、第１の実施形態と同様に、光学センサ４７２が硬貨を検出する際に、硬貨受容部４２４での硬貨の挙動が安定し、硬貨の直径が高精度に取得される。 The pressing member 562 is located between the light source 472a of the optical sensor 472 and the line sensor 472b. Therefore, the pressing member 562 corrects the posture of the coin by pressing the coin when the optical sensor 472 detects it. As a result, as in the first embodiment, when the optical sensor 472 detects a coin, the behavior of the coin at the coin receiving unit 424 is stabilized, and the diameter of the coin is acquired with high accuracy.

また、第２の実施形態においては、押圧部材５６２が硬貨の上面に接触するので、硬貨の直径を取得する上で、押圧部材５６２と硬貨の境界を識別するための凹部を押圧部材５６２に設けなくても良い。 In the second embodiment, since the pressing member 562 contacts the upper surface of the coin, a recess for identifying the boundary between the pressing member 562 and the coin is provided in the pressing member 562 in order to obtain the diameter of the coin. It is not necessary.

For this reason, the optical sensor 572 is a so-called reflective sensor, and the line sensor 572b receives light reflected by a coin.

上述した光学センサ５７２の構成によれば、光源５７２ａ及びラインセンサ５７２ｂを１箇所に集約して配置させることで、光学センサ５７２の配線も集約されるので、配置スペースの効率的が図れる。また、第３の実施形態でも、レバ部材４６２によって硬貨受容部４２４での硬貨の挙動が安定するので、硬貨の直径が高精度に取得される。 According to the configuration of the optical sensor 572 described above, by arranging the light source 572a and the line sensor 572b in one place, the wiring of the optical sensor 572 is also collected, so that the arrangement space can be made efficient. Also in the third embodiment, the lever member 462 stabilizes the behavior of the coin in the coin receiving portion 424, so that the diameter of the coin is acquired with high accuracy.

＜４．まとめ＞
上述したように、硬貨処理装置１００は、押圧部材（レバ部材４６２）及び硬貨受容部４２４の少なくともいずれか一方に凹部を有し、光学センサが、硬貨受容部に受容された硬貨と凹部を検出する。かかる構成によれば、押圧部材によって硬貨受容部での硬貨の挙動が安定し、硬貨と凹部が形成された部材との境界が明確になるので、硬貨の直径を高精度に検出できる。 <4. Summary>
