The plurality of brush portions have different outer diameters by having hair of a length implanted therein.

請求項3に係る発明は、請求項1または2に係る発明において、前記複数のブラシ部は植毛密度が互いに異なることを特徴としている。   The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the plurality of brush portions have different flocking densities.

請求項4に係る発明は、請求項1乃至3のいずれか一項に係る発明において、前記複数のブラシ部は毛の強度が互いに異なることを特徴としている。   The invention according to claim 4 is the invention according to any one of claims 1 to 3, characterized in that the plurality of brush portions have different bristle strengths.

請求項1に係る発明によれば、紙葉類の磁気的性質を検出する磁気センサに対向配置され、回転することで紙葉類を磁気センサに押し付けながら搬送するブラシローラの複数のブラシ部が互いに異なる外径となっているため、外径の大きいブラシ部で磁気センサに紙葉類を押し付け、外径の小さいブラシ部で紙葉類の磁気センサからの浮きを防止できる。したがって、十分な検出性能が得られる上、紙葉類が磁気センサとブラシローラとの間に入る際の搬送抵抗を低減することができ、搬送不良を抑制できる。   According to the first aspect of the present invention, the plurality of brush portions of the brush roller disposed opposite to the magnetic sensor for detecting the magnetic property of the paper sheet and transported while pressing the paper sheet against the magnetic sensor by rotating. Since the outer diameters are different from each other, the paper sheet can be pressed against the magnetic sensor with the brush part having a large outer diameter, and the paper sheet can be prevented from floating from the magnetic sensor with the brush part having a small outer diameter. Therefore, sufficient detection performance can be obtained, and conveyance resistance when paper sheets enter between the magnetic sensor and the brush roller can be reduced, and conveyance failure can be suppressed.

請求項2に係る発明によれば、ブラシローラは、中心の回転軸が複数のブラシ部の各配設位置の外径を異ならせており、この回転軸に同等長さの毛が植毛されることで複数のブラシ部が互いに外径を異ならせているため、複数のブラシ部の製造が容易となる。   According to the second aspect of the present invention, the brush roller has a central rotation shaft that has different outer diameters at the positions where the plurality of brush portions are disposed, and hairs of the same length are implanted on the rotation shaft. Thus, since the plurality of brush portions have different outer diameters, the manufacture of the plurality of brush portions is facilitated.

請求項3に係る発明によれば、複数のブラシ部は植毛密度が互いに異なるため、紙葉類が磁気センサとブラシローラとの間に入る際の搬送抵抗をさらに低減することができる。   According to the third aspect of the present invention, since the plurality of brush portions have different flocking densities, it is possible to further reduce the conveyance resistance when paper sheets enter between the magnetic sensor and the brush roller.

請求項4に係る発明によれば、複数のブラシ部は毛の強度が互いに異なるため、紙葉類が磁気センサとブラシローラとの間に入る際の搬送抵抗をさらに低減することができる。   According to the invention which concerns on Claim 4, since the intensity | strength of a some brush part differs mutually, conveyance resistance at the time of paper sheets entering between a magnetic sensor and a brush roller can further be reduced.

そして、例えば、入金処理時には、入金口32に投入され入金部15から主搬送路38に一枚ずつ繰り出された紙幣Sが、主搬送路38での搬送中に入金識別部47で識別されることになり、この入金識別部47での識別結果に基づいて、制御部が、還流庫20〜22用の振分部42G,43Gのうち該当する金種への振分用のものを必要により開作動させて、金種の還流庫20〜22のうちの該当するものに紙幣Sを搬送する。ここでは、入金可能な千円券紙幣であった場合には主搬送路38でそのまま還流庫22の中間プール部22aに貯留させ、入金可能な万円券紙幣であった場合には振分部42Gで分岐搬送路42を介して還流庫20の中間プール部20aに貯留させ、入金可能な五千円券紙幣であった場合には振分部43Gで分岐搬送路43を介して還流庫21の中間プール部21aに貯留させる。そして、入金確定操作が入力されたことを条件に中間プール部20a〜22aから紙幣Sを収納部20b〜22bに収納させる。他方、入金可能であるものの還流庫を持たない二千円券紙幣や還流庫20〜22のいずれか満杯状態の紙幣については、回収庫17への振分部40Gを開作動させるとともに、搬送部37を逆転させて振分部40Gで分岐搬送路40を介して回収庫17に収納させる。また、入金識別部47で入金不可な紙幣Sと識別された場合、制御部は、回収庫17への振分部40Gを開作動させ、搬送部37を逆転させて当該紙幣Sを振分部43Gで分岐搬送路40を介して回収庫17に搬送するか、あるいは、出金部16への振分部39Gを開作動させ、搬送部37を逆転させて当該紙幣Sを振分部39Gで分岐搬送路39を介して出金部16に搬送し、出金部16から機外に取出可能な状態として、操作者に返却する。   For example, during the deposit process, the banknotes S inserted into the deposit port 32 and fed out one by one from the deposit unit 15 to the main conveyance path 38 are identified by the deposit identification unit 47 during conveyance on the main conveyance path 38. Therefore, based on the identification result in the deposit identification unit 47, the control unit needs to allocate the denomination to the corresponding denomination among the distribution units 42G and 43G for the reflux containers 20-22. The banknote S is transported to the corresponding one of the denomination reflux warehouses 20 to 22 by opening. Here, if it is a depositable thousand yen bill, it is stored in the intermediate pool portion 22a of the reflux warehouse 22 as it is in the main transport path 38, and if it is a depositable 10,000 yen bill, a sorting portion is stored. 42G is stored in the intermediate pool part 20a of the reflux warehouse 20 via the branch conveyance path 42, and when it is a 5,000-yen bill that can be deposited, the reflux warehouse 21 via the branch conveyance path 43 at the sorting part 43G. In the intermediate pool portion 21a. And the banknote S is accommodated in the accommodating parts 20b-22b from intermediate | middle pool part 20a-22a on condition that the payment confirmation operation was input. On the other hand, for a 2,000-yen note banknote that can be deposited but does not have a return box or a banknote in any of the return boxes 20-22, the sorting unit 40G to the collection box 17 is opened and the transport unit 37 is reversed and stored in the collection box 17 via the branch conveyance path 40 by the sorting unit 40G. When the deposit identifying unit 47 identifies the banknote S that cannot be deposited, the control unit opens the sorting unit 40G to the collection box 17, reverses the transport unit 37, and transfers the bill S to the sorting unit. 43G is conveyed to the collection | recovery store | warehouse | chamber 17 via the branch conveyance path 40, or the distribution part 39G to the withdrawal part 16 is opened, the conveyance part 37 is reversed, and the said banknote S is distributed by the distribution part 39G. It is conveyed to the dispensing unit 16 via the branch conveyance path 39 and returned to the operator as a state where it can be taken out from the dispensing unit 16 to the outside of the machine.

また、例えば、出金処理時には、還流庫20〜22のいずれか一つから紙幣Sを主搬送路38を介して出金部16側に向けて搬送することになり、主搬送路38の搬送中に出金識別部48で識別する。出金識別部48によって紙幣Sが重送ではないと識別されると、制御部は、出金部16への振分用の振分部39Gを開作動させることで当該紙幣Sを出金部16に受け入れ可能な状態とし分岐搬送路39を介して出金部16に送り込む。他方、出金識別部48で出金不可な重送紙幣と識別された場合、制御部は、出金リジェクト庫18への振分部41Gを開作動させ、搬送部37を逆転させて当該紙幣Sを振分部41Gで分岐搬送路41を介して出金リジェクト庫18に搬送する。そして、出金部16への紙幣Sの搬送を適宜繰り返すことで、出金する枚数の紙幣Sが出金部16に送り込まれると、出金部16はこの紙幣Sを出金口33から機外に取り出し可能な状態とする。   For example, at the time of the withdrawal process, the banknote S is transported from any one of the reflux warehouses 20 to 22 toward the withdrawal unit 16 via the main transport path 38, and is transported by the main transport path 38. The withdrawal is identified by the withdrawal identification unit 48.

第1実施形態の紙葉類磁気検出装置10は、中間搬送路45で搬送中の紙幣Sの磁気的性質を検出する磁気センサ59と、磁気センサ59に対向配置され、中間搬送路45と同期回転することで紙幣Sを磁気センサ59に押し付けながら搬送するブラシローラ60とを有している。   The paper sheet magnetism detection device 10 according to the first embodiment is disposed opposite to the magnetic sensor 59 for detecting the magnetic property of the bill S being conveyed in the intermediate conveyance path 45, and is synchronized with the intermediate conveyance path 45. The brush roller 60 conveys the banknote S while pressing it against the magnetic sensor 59 by rotating.

磁気センサ59は、中間搬送路45で搬送される紙幣Sの搬送方向に直交する方向の幅の全体を検出可能な検出面59aを有しており、この検出面59aを中間搬送路45の搬送方向に沿わせた状態でブラシローラ60側に向けている。   The magnetic sensor 59 has a detection surface 59 a that can detect the entire width in the direction orthogonal to the conveyance direction of the banknote S conveyed on the intermediate conveyance path 45, and this detection surface 59 a is conveyed on the intermediate conveyance path 45. It is directed toward the brush roller 60 in a state along the direction.

ブラシローラ60は、図4に示す支持部62で磁気センサ59に対し常に一定の位置に回転可能に支持されるとともに図示略のモータの駆動で回転する回転軸63を有している。この回転軸63は、その中心軸線が中間搬送路45で搬送される紙幣Sと平行かつ紙幣Sの搬送方向に直交する方向に沿っている。   The brush roller 60 has a rotating shaft 63 that is supported by a support portion 62 shown in FIG. 4 so as to be always rotatable at a fixed position with respect to the magnetic sensor 59 and that is rotated by driving of a motor (not shown). The rotation axis 63 is parallel to the bill S transported by the intermediate transport path 45 along the central axis thereof and is orthogonal to the bill S transport direction.

回転軸63は、図4に示すように、複数具体的には三カ所の同等のブラシ形成部69を有している。各ブラシ形成部69は、それぞれ、軸線方向において等幅であって互いに同軸同径の複数の大径軸部64と、大径軸部64に対し等幅かつ小径であって互いに同軸同径の複数の小径軸部65とを有しており、大径軸部64と小径軸部65とが軸線方向に交互に配置されている。また、各ブラシ形成部69は、それぞれ、大径軸部64および小径軸部65の全配設範囲の両端に、小径軸部65が配置されており、これら小径軸部65の両側に、大径側が大径軸部64と同軸同径で外側ほど小径となるテーパ軸部66を有している。さらに、各ブラシ形成部69は、それぞれ、各テーパ軸部66の外側にテーパ軸部66の小径側と同軸同径の中心軸部67を有しており、隣り合うブラシ形成部69は中心軸部67が共通している。そして、中心軸部67のうち最も両端側の中心軸部67が支持部62に回転可能に支持されている。   As shown in FIG. 4, the rotating shaft 63 has a plurality of specifically three equivalent brush forming portions 69. Each brush forming portion 69 has a plurality of large-diameter shaft portions 64 having the same width in the axial direction and having the same coaxial diameter, and the same diameter and smaller diameter with respect to the large-diameter shaft portion 64 and having the same coaxial diameter. A plurality of small-diameter shaft portions 65 are provided, and the large-diameter shaft portions 64 and the small-diameter shaft portions 65 are alternately arranged in the axial direction. In addition, each brush forming portion 69 has a small-diameter shaft portion 65 disposed at both ends of the entire arrangement range of the large-diameter shaft portion 64 and the small-diameter shaft portion 65, respectively. It has a tapered shaft portion 66 whose diameter side is coaxial with the large diameter shaft portion 64 and has a smaller diameter toward the outside. Further, each brush forming portion 69 has a central shaft portion 67 that is coaxial with the small diameter side of the tapered shaft portion 66 on the outer side of each tapered shaft portion 66, and the adjacent brush forming portions 69 have a central axis. The part 67 is common. The center shaft portion 67 at the most end side of the center shaft portion 67 is rotatably supported by the support portion 62.

そして、各ブラシ形成部69において、上記した回転軸63のすべての大径軸部64とすべての小径軸部65とには、それぞれの半径方向に沿う状態で、同等の材質、同等の太さ、同等の長さの多数の毛68が、同等の密度となるように植毛されている。大径軸部64に植毛された多数の毛68で構成される大径ブラシ部(ブラシ部)70と小径軸部65に植毛された多数の毛68で構成される小径ブラシ部(ブラシ部)71とは、これら大径ブラシ部70および小径ブラシ部71の各配設位置となる大径軸部64および小径軸部65の外径が異なっていることから、互いに外径が異なっている。そして、大径ブラシ部70と小径ブラシ部71とがブラシローラ60の軸線方向において交互に配置されており、その結果、ブラシローラ60の各ブラシ形成部69は、軸線方向に凹凸を繰り返す形状をなしている。ここで、例えば、小径軸部65の外径は大径軸部64の外径の外径よりも0.6mm〜1mmの範囲で小径となっており、大径ブラシ部70の先端と小径ブラシ部71の先端とに0.3mm〜0.5mm程度の段差が設けられている。   In each brush forming portion 69, all the large-diameter shaft portions 64 and all the small-diameter shaft portions 65 of the rotating shaft 63 have the same material and the same thickness in a state along the respective radial directions. A number of hairs 68 having the same length are implanted so as to have the same density. A large-diameter brush portion (brush portion) 70 composed of a large number of hairs 68 planted on the large-diameter shaft portion 64 and a small-diameter brush portion (brush portion) composed of a large number of hairs 68 planted on the small-diameter shaft portion 65. Since the outer diameters of the large-diameter shaft portion 64 and the small-diameter shaft portion 65 at which the large-diameter brush portion 70 and the small-diameter brush portion 71 are disposed are different from 71, the outer diameters are different from each other. And the large diameter brush part 70 and the small diameter brush part 71 are alternately arrange | positioned in the axial direction of the brush roller 60, As a result, each brush formation part 69 of the brush roller 60 has the shape which repeats an unevenness | corrugation in an axial direction. There is no. Here, for example, the outer diameter of the small-diameter shaft portion 65 is smaller in the range of 0.6 mm to 1 mm than the outer diameter of the large-diameter shaft portion 64, and the tip of the large-diameter brush portion 70 and the small-diameter brush A step of about 0.3 mm to 0.5 mm is provided at the tip of the portion 71.

また、両側のテーパ軸部66も多数の毛68が植毛されてブラシ部72が構成されているが、これらのブラシ部72は上記と同等の材質および同等の太さの毛68が同等の密度で植毛されており、ブラシ部72の外径が一定となるように毛68の長さのみ調整されている。   Also, the brush shafts 72 are formed by planting a large number of bristles 68 on the tapered shaft portions 66 on both sides, and these brush portions 72 are composed of bristles 68 having the same material and the same thickness as the above. The length of the hair 68 is adjusted so that the outer diameter of the brush portion 72 is constant.

そして、小径軸部65に設けられた小径ブラシ部71が、磁気センサ59の検出面59aに対し最も近接した状態でこの検出面59aとの間に紙幣一枚分の隙間を形成し、大径軸部64に設けられた大径ブラシ部70が、磁気センサ59の検出面59aに対し毛68の先端側所定長さの範囲が接触可能(オーバーラップ可能)となるように、ブラシローラ60の磁気センサ59に対する位置が決められている。   And the small diameter brush part 71 provided in the small diameter shaft part 65 forms the clearance gap for one banknote between this detection surface 59a in the state closest to the detection surface 59a of the magnetic sensor 59, and is large diameter. The large-diameter brush portion 70 provided on the shaft portion 64 of the brush roller 60 is configured such that a range of a predetermined length on the front end side of the bristles 68 can contact (overlapping) the detection surface 59a of the magnetic sensor 59. The position with respect to the magnetic sensor 59 is determined.

中間搬送路45での紙幣Sの搬送中に紙幣磁気検出装置10はそのブラシローラ60が中間搬送路45と同期して搬送方向を同じとするように回転することになるが、ブラシローラ60は、大径軸部64に設けられた大径側の大径ブラシ部70が主として先端部を撓ませながら紙幣Sを検出面59aに押し付けることになり、小径軸部65の小径ブラシ部71が紙幣Sの検出面59aからの浮きを抑えることになる。   While the banknote S is being transported in the intermediate transport path 45, the bill magnetism detection device 10 rotates so that the brush roller 60 is synchronized with the intermediate transport path 45 and the transport direction is the same. The large-diameter side large-diameter brush portion 70 provided on the large-diameter shaft portion 64 mainly presses the bill S against the detection surface 59a while bending the tip portion, and the small-diameter brush portion 71 of the small-diameter shaft portion 65 serves as the bill. S is prevented from floating from the detection surface 59a.

以上に述べた本実施形態の紙葉類磁気検出装置10によれば、紙幣Sの磁気的性質を検出する磁気センサ59に対向配置され、回転することで紙幣Sを磁気センサ59に押し付けながら搬送するブラシローラ60の回転軸63が、異なる外径の複数の大径軸部64および複数の小径軸部65を交互に有しており、回転軸63の大径軸部64および小径軸部65に植毛される複数の大径ブラシ部70および複数の小径ブラシ部71が互いに異なる外径となっているため、外径の大きい大径ブラシ部70で磁気センサ59に紙幣Sを押し付け、外径の小さい小径ブラシ部71で紙幣Sの磁気センサ59からの浮きを防止できる。したがって、十分な検出性能が得られる上、紙幣Sが磁気センサ59とブラシローラ60との間に入る際の搬送抵抗を低減することができ、搬送不良を抑制できる。   According to the paper sheet magnetic field detection device 10 of the present embodiment described above, the paper sheet S is disposed opposite to the magnetic sensor 59 that detects the magnetic property of the banknote S, and is conveyed while pressing the banknote S against the magnetic sensor 59 by rotating.

Since the plurality of large-diameter brush portions 70 and the plurality of small-diameter brush portions 71 to be planted have different outer diameters, the bill S is pressed against the magnetic sensor 59 by the large-diameter brush portion 70 having a large outer diameter. The small-diameter brush portion 71 having a small diameter can prevent the banknote S from floating from the magnetic sensor 59. Accordingly, sufficient detection performance can be obtained, and conveyance resistance when the bill S enters between the magnetic sensor 59 and the brush roller 60 can be reduced, and conveyance failure can be suppressed.

また、ブラシローラ60は、中心の回転軸63が大径ブラシ部70および小径ブラシ部71の各配設位置となる大径軸部64および小径軸部65の外径を異ならせており、この回転軸63に同等長さの毛が植毛されることで大径ブラシ部70および小径ブラシ部71が互いに外径を異ならせているため、大径ブラシ部70および小径ブラシ部71の製造が容易となる。   In the brush roller 60, the outer diameter of the large-diameter shaft portion 64 and the small-diameter shaft portion 65 in which the central rotation shaft 63 is disposed at each of the large-diameter brush portion 70 and the small-diameter brush portion 71 is different. Since the large-diameter brush portion 70 and the small-diameter brush portion 71 have different outer diameters by having bristles of the same length implanted on the rotary shaft 63, the large-diameter brush portion 70 and the small-diameter brush portion 71 can be easily manufactured. It becomes.
