Description

【０００１】
【発明の属する技術分野】
本発明は、例えば自動紙幣処理機等に用いられ、紙幣等に書込まれた磁気データから出力を読取る磁気読取装置に関する。
【０００２】
【従来の技術】
従来、銀行等の金融機関で利用される自動紙幣処理機には、紙幣の金種等を認識する装置があるが、その装置の機能のひとつとして、紙幣の搬送中に磁気出力を読取る機能がある。この機能を実現するため、磁気センサと、紙幣を磁気センサに押し当てる押圧部材が設けられていた。紙幣がこの押圧部材により磁気センサに押圧されることで紙幣の磁気出力を磁気センサで検知し、この磁気出力の特徴をとらえることにより紙幣の金種等の認識をすることが可能であった。
【０００３】
図９、図１０に示すように、従来の磁気読取部（磁気センサ、押圧部材）は、フレーム４に支持された磁気センサ１と、紙幣６を磁気センサ１に押し当て、フレーム３に支持された押圧部材２とから構成されている。前記磁気センサ１の頂部は、紙幣６と摺動して磁気読取りを行うギャップ１ａが設けられ磁気出力を検知する。 前記押圧部材２は磁気読取を安定させるため弾性部材等で形成され前記磁気センサ１に対向配置されている。
【０００４】
前記押圧部材２の頂部の形状は紙幣６を安定して搬送するために、紙幣６が搬送される方向に円弧形状に形成され、円弧形状の一部を磁気センサ１にスプリング８によって押し当てる構造になっている。また、紙幣６が搬送される方向に対して直角方向では平らな面になっている。フレーム３とフレーム４の間に紙幣搬送路７を形成している。
【０００５】
【発明が解決しようとする課題】
このような従来の磁気読取装置において、押圧部材２は紙幣６が搬送される方向に円弧形状に形成されており、円弧形状の一部を磁気センサ１のギャップ１ａにスプリング８にて押し当てる構造になっていたが、紙幣６は搬送路７を搬送され前記磁気読取部の前記磁気センサ１のギャップ１ａと前記押圧部材２との円弧部の接触点に到達すると、紙幣６は該接触点に衝突し次に通過する。
【０００６】
この時の衝突による衝撃とその後の通過（読取）による摩擦により前記押圧部材２が摩耗して段差が形成される。この段差によりスティックスリップの現象（磁気センサのギャップ１ａに対応する位置の押圧部材に紙幣６が衝突し、衝突によるノイズが発生して不安定な磁気読取になる）を引き起こすという問題があった。
【０００７】
また、紙幣６が搬送される方向に対して直角方向では磁気読取りを行う磁気センサのギャップ部分１ａに押圧部材２が密着しないで磁気出力を不安定にするという問題があった。
【０００８】
【課題を解決するための手段】
本発明は、上記課題を解決するために，押圧部材のパッドの両端に例えば金属の様な前記パッドより摩耗し難い材料にてガイドを設ける。
【０００９】
また、押圧部材を支持するフレームに例えば金属のような、押圧部材より摩耗し難い材料にてリブを設ける。
【００１０】
また、紙幣の衝突の位置を磁気センサのギャップの位置からずらす。
【００１１】
また、押圧部材の紙幣の搬送方向と直角方向の角をＲ形状に形成する。ことを特徴とする。
【００１２】
【発明の実施の形態】
以下、本発明の実施の形態について、図面を用いて説明する。なを、各図面に共通する要素には同一の符号を付す。
図１は第１の実施の形態を示す磁気読取部を説明するための正面図であり、図２は図１の側面図である。図３は第２の実施の形態を示す磁気読取部を説明するための正面図であり、図４は図３の側面図である。図５は第３の実施の形態を示す磁気読取部を説明するための正面図であり、図６は図５の側面図である。図７は第４の実施の形態を示す磁気読取部を説明するための正面図であり、図８は図７の側面図である。図９は従来の磁気読取部を説明するための側面図であり、図１０は図９のＡ部拡大図である。
【００１３】
第１の実施の形態を示す磁気読取部は、図１、図２を用いて説明する。磁気センサ１はフレーム４に支持され、押圧部材２０はフレーム３に支持され紙幣６をスプリング８にて磁気センサ１に押し当てる。前記磁気センサ１の頂部は、前記紙幣６と摺動して磁気読取りを行うギャップ１ａが設けられ磁気出力を検知する。前記押圧部材２０はパッド２１とガイド２２、２３からから構成されている。
前記パッド２１は弾性部材等で形成されている。
【００１４】
前記パッド２１の両端には例えば金属の様な前記パッド２１より摩耗し難い材料にてガイド２２、２３を設けてある。このパッド２１と両端の前記ガイド２２、２３は例えば接着等により一体に構成され、前記磁気センサ１に対向配置されている。前記パッド２１と前記ガイド２１、２２の頂部の形状は紙幣６を安定して搬送するために、紙幣６が搬送される方向に円弧形状に形成され、該円弧形状の一部を磁気センサ１のギャップ１ａにスプリング８によって押し当てる構造になっている。
【００１５】
このように構成された磁気読取部は次のように作用する。紙幣６は搬送路７を搬送され前記磁気読取部の前記磁気センサ１のギャップ１ａと前記押圧部材２０との円弧部の接触点に到達すると、紙幣６は該接触点に衝突し次に通過する。この時の衝突による衝撃とその後の通過（読取）による摩擦により前記磁気センサ１と前記押圧部材２０との円弧部の接触点が摩耗して段差が生じるが、パッド２１の両端には例えば金属の様な前記パッド２１より摩耗し難い材料にてガイド２２、２３を設けてあるので、摩耗が減少してスティックスリップの現象を引き起こすことがなくなる。
【００１６】
第２の実施の形態を示す磁気読取部は、図３、図４を用いて説明する。磁気センサ１はフレーム４に支持され、押圧部材２はフレーム３０に支持され紙幣６をスプリング８にて前記磁気センサ１に押し当てる。前記磁気センサ１の頂部は、前記紙幣６と摺動して磁気読取りを行うギャップ１ａが設けられ磁気出力を検知する。前記押圧部材２は弾性部材等で形成されている。
【００１７】
前記フレーム３０にはリブ３１、３２が紙幣６の搬送方向と直角方向に前記押圧部材２を保護する形状に設けられている。すなわち、前記フレーム３０に支持された前記押圧部材２の幅方向の外側の所定の位置に、例えば金属の様な前記押圧部材２より摩耗し難い材料にて、リブ３１、３２を設ける。このフレーム３０と前記リブ３１、３２は例えば接着等により一体に取り付けられるか、また一体成形により成形されても良い。
【００１８】
前記リブ３１、３２は、ほぼ前記磁気センサ１に接する高さで紙幣６の走行方向に、前記磁気センサ１のギャップ１ａの位置から前後に長く平面状に形成され、これにより衝突位置を前記ギャップ１ａの位置からずらすようにしている。また前記押圧部材２は紙幣６を安定して搬送するために、紙幣６が搬送される方向に円弧形状に形成され、該円弧形状の一部を前記磁気センサ１のギャップ１ａにスプリング８によって押し当てる構造になっている。したがって、前記押圧部材２の側面からみた形状は完全に前記リブ３１、３２の形状の中に納まっている。
【００１９】
このように構成された磁気読取部は次のように作用する。紙幣６は搬送路７を搬送され前記磁気読取部の前記リブ３１、３２の先端部３１ａ，３２ａに衝突する。次に前記磁気センサ１のギャップ１ａと前記押圧部材２との円弧部の接触点に到達する。紙幣６は前記接触点にて前記押圧部材２に衝突し次に通過する。
【００２０】
しかしながら、この時の衝突による前記押圧部材２への衝撃は前記リブ３１、３２によって紙幣６の走行が案内されているので小さい。前記リブ３１、３２は例えば金属の様な前記押圧部材２より摩耗し難い材料にて設けてあるので、衝突による衝撃とその後の通過（読取）による摩擦による摩耗が減少してスティックスリップの現象を引き起こすことがなくなった。
【００２１】
第３の実施の形態を示す磁気読取部は、図５、図６を用いて説明する。フレーム４に支持された磁気センサ１と、紙幣６を磁気センサ１に押し当て、フレーム３に支持された押圧部材４０とから構成されている。前記磁気センサ１の頂部には、紙幣６と摺動して磁気読取りを行うギャップ１ａが設けられ磁気出力を検知する。前記押圧部材４０は磁気読取を安定させるため弾性部材等で形成され前記磁気センサ１に対向配置されている。
【００２２】
前記押圧部材４０の頂部の形状は前記磁気センサ１に接する高さで紙幣６の走行方向に、磁気センサ１のギャップ１ａの位置から前後に長く平面状に形成され、これにより衝突位置４０ａをギャップ１ａの位置からずらすようにしている。また、前記平面状に形成された前後端は、紙幣６の衝突を和らげるために、紙幣６が搬送される方向にＲ形状に形成されている。前記平面部を磁気センサ１にスプリング８によって押し当てる構造になっている。
【００２３】
このように構成された磁気読取部は次のように作用する。紙幣６は搬送路７を搬送され前記磁気読取部の前記押圧部材４０の先端部４０ａに衝突する。次に前記磁気センサ１のギャップ１ａと前記押圧部材４０の前記平面部接触点に到達する。紙幣６は前記平面部接触点にて読取りを行う。これにより衝突による前記磁気センサ１のギャップ１ａの位置の摩耗が減少してスティックスリップの現象を引き起こすことがなくなる。
【００２４】
第４の実施の形態を示す磁気読取部は、図７、図８を用いて説明する。フレーム４に支持された磁気センサ１と、紙幣６を磁気センサ１に押し当て、フレーム３に支持された押圧部材５０とから構成されている。前記磁気センサ１の頂部には、紙幣６と摺動して磁気読取りを行うギャップ１ａが設けられ磁気出力を検知する。前記押圧部材５０は磁気読取を安定させるため弾性部材等で形成され前記磁気センサ１に対向配置されている。
【００２５】
前記押圧部材５０は紙幣６が搬送される方向に円弧形状に形成されており、円弧形状の一部を前記磁気センサ１のギャップ１ａにスプリング８にて押し当てる構造になっている。また、紙幣６の搬送方向と直角方向の角をＲ形状に形成されている。
【００２６】
このように構成された磁気読取部は次のように作用する。紙幣６は搬送路７を搬送され前記磁気読取部の前記磁気センサ１のギャップ１ａと前記押圧部材５０との円弧部の接触点に到達する。その後の通過（読取）にて、前記押圧部材５０の紙幣６の搬送方向と直角方向の角をＲ形状に形成しているので、紙幣６が搬送される方向に対して直角方向では磁気読取りを行う前記磁気センサのギャップ部分１ａ(幅)に押圧部材が隙間なく密着し、これにより磁気出力が安定する。
【００２７】
【発明の効果】
以上述べたように本発明によれば、押圧部材２０のパッド２１の両端には例えば金属の様な前記パッド２１より摩耗し難い材料にてガイド２２、２３を設けているので、衝突による衝撃とその後の通過（読取）による摩擦による摩耗が減少してスティックスリップの現象を引き起こすことがなくなった。
【００２８】
また、フレーム３０に例えば金属のような、押圧部材２より摩耗し難い材料にてリブ３１、３２を設けてあるので、衝突による衝撃とその後の通過（読取）による摩擦による摩耗が減少してスティックスリップの現象を引き起こすことがなくなった。
【００２９】
また、押圧部材４０の紙幣６との衝突の位置を、磁気センサ１のギャップ１ａの位置からずらして衝突による磁気センサ１のギャップ１ａの位置の摩耗を減少して、スティックスリップの現象を引き起こすことがなくなった。
【００３０】
また、押圧部材５０の紙幣６の搬送方向と直角方向の角をＲ形状に形成しているので、紙幣６が搬送される方向に対して直角方向では磁気読取りを行う磁気センサのギャップ部分１ａ（幅）に押圧部材５０が隙間なく密着し、これにより磁気出力が安定にする。

BACKGROUND OF THE INVENTION
The present invention relates to a magnetic reader that is used in, for example, an automatic banknote processing machine and reads output from magnetic data written on a banknote or the like.
[0002]
[Prior art]
Conventionally, automatic banknote processing machines used in financial institutions such as banks have a device for recognizing the denomination of banknotes, etc. As one of the functions of the device, there is a function of reading a magnetic output during conveyance of banknotes. is there. In order to realize this function, a magnetic sensor and a pressing member that presses a bill against the magnetic sensor are provided. When the banknote is pressed against the magnetic sensor by the pressing member, the magnetic output of the banknote is detected by the magnetic sensor, and the denomination of the banknote can be recognized by capturing the characteristics of the magnetic output.
[0003]
As shown in FIGS. 9 and 10, the conventional magnetic reading unit (magnetic sensor, pressing member) presses the magnetic sensor 1 supported by the frame 4 and the bill 6 against the magnetic sensor 1 and is supported by the frame 3. And the pressing member 2. The top of the magnetic sensor 1 is provided with a gap 1a that slides on the banknote 6 and performs magnetic reading, and detects a magnetic output. The pressing member 2 is formed of an elastic member or the like to stabilize magnetic reading, and is disposed opposite to the magnetic sensor 1.
[0004]
The shape of the top of the pressing member 2 is formed in an arc shape in the direction in which the bill 6 is conveyed in order to stably convey the bill 6, and a part of the arc shape is pressed against the magnetic sensor 1 by the spring 8. It has become. Moreover, it is a flat surface in the direction perpendicular to the direction in which the bills 6 are conveyed. A bill conveyance path 7 is formed between the frame 3 and the frame 4.
[0005]
[Problems to be solved by the invention]
In such a conventional magnetic reading apparatus, the pressing member 2 is formed in an arc shape in the direction in which the bill 6 is conveyed, and a structure in which a part of the arc shape is pressed against the gap 1 a of the magnetic sensor 1 by the spring 8. However, when the bill 6 is transported through the transport path 7 and reaches the contact point of the arc portion between the gap 1a of the magnetic sensor 1 and the pressing member 2 of the magnetic reading unit, the bill 6 reaches the contact point. Collide and then pass.
[0006]
The pressing member 2 is worn by the impact caused by the collision at this time and the friction caused by the subsequent passage (reading) to form a step. There is a problem that this step causes a stick-slip phenomenon (the bill 6 collides with the pressing member at a position corresponding to the gap 1a of the magnetic sensor, and noise due to the collision is generated, resulting in unstable magnetic reading).
[0007]
Further, in the direction perpendicular to the direction in which the bills 6 are conveyed, there is a problem that the magnetic output is unstable because the pressing member 2 does not adhere to the gap portion 1a of the magnetic sensor that performs magnetic reading.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides guides at both ends of the pad of the pressing member with a material that is less likely to wear than the pad, such as metal.
[0009]
Further, ribs are provided on the frame that supports the pressing member with a material that is harder to wear than the pressing member, such as metal.
[0010]
Further, the position of the banknote collision is shifted from the position of the gap of the magnetic sensor.
[0011]
Moreover, the corner | angular of a perpendicular direction with the conveyance direction of the banknote of a press member is formed in R shape. It is characterized by that.
[0012]

FIG. 3 is a front view for explaining the magnetic reading unit according to the second embodiment, and FIG. 4 is a side view of FIG. FIG. 5 is a front view for explaining a magnetic reading unit according to the third embodiment, and FIG. 6 is a side view of FIG. FIG. 7 is a front view for explaining a magnetic reading unit according to the fourth embodiment, and FIG. 8 is a side view of FIG. FIG. 9 is a side view for explaining a conventional magnetic reading unit, and FIG. 10 is an enlarged view of part A of FIG.
[0013]
The magnetic reading unit showing the first embodiment will be described with reference to FIGS. The magnetic sensor 1 is supported by the frame 4, the pressing member 20 is supported by the frame 3, and the banknote 6 is pressed against the magnetic sensor 1 by the spring 8. The top of the magnetic sensor 1 is provided with a gap 1a that slides on the bill 6 and performs magnetic reading, and detects a magnetic output. The pressing member 20 includes a pad 21 and guides 22 and 23.
The pad 21 is formed of an elastic member or the like.
[0014]
Guides 22 and 23 are provided at both ends of the pad 21 with a material that is less likely to be worn away than the pad 21 such as metal. The pad 21 and the guides 22 and 23 at both ends are integrally formed by bonding or the like, for example, and are disposed to face the magnetic sensor 1. The top shape of the pad 21 and the guides 21 and 22 is formed in an arc shape in the direction in which the bill 6 is conveyed in order to stably convey the bill 6, and a part of the arc shape is formed on the magnetic sensor 1. The gap 1a is pressed by a spring 8.
[0015]
The magnetic reading unit configured as described above operates as follows. When the bill 6 is transported through the transport path 7 and reaches the contact point of the arc portion between the gap 1a of the magnetic sensor 1 of the magnetic reading unit and the pressing member 20, the bill 6 collides with the contact point and passes next. . The contact point of the arc portion of the magnetic sensor 1 and the pressing member 20 is worn by the impact due to the collision at this time and the friction due to the subsequent passage (reading), and a step is generated. Since the guides 22 and 23 are made of a material that is harder to wear than the pad 21, the wear is reduced and the stick-slip phenomenon does not occur.
[0016]
A magnetic reading unit according to the second embodiment will be described with reference to FIGS. The magnetic sensor 1 is supported by the frame 4, the pressing member 2 is supported by the frame 30, and the banknote 6 is pressed against the magnetic sensor 1 by the spring 8. The top of the magnetic sensor 1 is provided with a gap 1a that slides on the bill 6 and performs magnetic reading, and detects a magnetic output. The pressing member 2 is formed of an elastic member or the like.
[0017]
Ribs 31 and 32 are provided on the frame 30 so as to protect the pressing member 2 in a direction perpendicular to the conveyance direction of the bills 6. That is, the ribs 31 and 32 are provided at a predetermined position on the outer side in the width direction of the pressing member 2 supported by the frame 30 with a material that is less likely to be worn than the pressing member 2 such as metal. The frame 30 and the ribs 31 and 32 may be integrally attached, for example, by bonding or may be formed by integral molding.
[0018]
The ribs 31 and 32 are formed in a planar shape long in the front-rear direction from the position of the gap 1a of the magnetic sensor 1 in the running direction of the bill 6 at a height substantially in contact with the magnetic sensor 1, and thereby the collision position is set to the gap. The position is shifted from the position 1a. The pressing member 2 is formed in an arc shape in the direction in which the bill 6 is conveyed in order to stably convey the bill 6, and a part of the arc shape is pushed to the gap 1 a of the magnetic sensor 1 by the spring 8. It has a structure to hit. Therefore, the shape seen from the side surface of the pressing member 2 is completely contained in the shape of the ribs 31 and 32.
[0019]
The magnetic reading unit configured as described above operates as follows. The bill 6 is transported through the transport path 7 and collides with the tip portions 31a and 32a of the ribs 31 and 32 of the magnetic reading unit. Next, the contact point of the arc portion between the gap 1 a of the magnetic sensor 1 and the pressing member 2 is reached. The bill 6 collides with the pressing member 2 at the contact point and then passes.
[0020]
However, the impact on the pressing member 2 due to the collision at this time is small because the running of the bill 6 is guided by the ribs 31 and 32. Since the ribs 31 and 32 are made of a material that is harder to wear than the pressing member 2 such as metal, wear due to collision and friction due to subsequent passage (reading) is reduced, thereby causing a stick-slip phenomenon. No longer cause.
[0021]
A magnetic reading unit according to the third embodiment will be described with reference to FIGS. The magnetic sensor 1 is supported by the frame 4, and the banknote 6 is pressed against the magnetic sensor 1, and the pressing member 40 is supported by the frame 3. At the top of the magnetic sensor 1, there is provided a gap 1a that slides on the bill 6 and performs magnetic reading to detect magnetic output. The pressing member 40 is formed of an elastic member or the like to stabilize the magnetic reading, and is disposed opposite to the magnetic sensor 1.
[0022]
The shape of the top of the pressing member 40 is a height that is in contact with the magnetic sensor 1 and is formed in a flat shape in the running direction of the banknote 6 from the position of the gap 1a of the magnetic sensor 1 to the front and back, thereby forming the gap at the collision position 40a. The position is shifted from the position 1a. Moreover, the front and rear ends formed in the planar shape are formed in an R shape in the direction in which the bill 6 is conveyed in order to reduce the collision of the bill 6. The flat portion is pressed against the magnetic sensor 1 by a spring 8.
[0023]
The magnetic reading unit configured as described above operates as follows. The bill 6 is transported through the transport path 7 and collides with the front end portion 40a of the pressing member 40 of the magnetic reading unit. Next, the gap 1a of the magnetic sensor 1 and the flat portion contact point of the pressing member 40 are reached. The bill 6 is read at the contact point of the flat surface. As a result, wear at the position of the gap 1a of the magnetic sensor 1 due to the collision is reduced, and a stick-slip phenomenon is not caused.
[0024]
A magnetic reading unit according to the fourth embodiment will be described with reference to FIGS. The magnetic sensor 1 is supported by the frame 4, and the banknote 6 is pressed against the magnetic sensor 1, and the pressing member 50 is supported by the frame 3. At the top of the magnetic sensor 1, there is provided a gap 1a that slides on the bill 6 and performs magnetic reading to detect magnetic output. The pressing member 50 is formed of an elastic member or the like to stabilize magnetic reading, and is disposed opposite to the magnetic sensor 1.
[0025]
The pressing member 50 is formed in an arc shape in the direction in which the bill 6 is conveyed, and has a structure in which a part of the arc shape is pressed against the gap 1 a of the magnetic sensor 1 by a spring 8. Moreover, the corner | angular of the orthogonal direction with the conveyance direction of the banknote 6 is formed in R shape.
[0026]
The magnetic reading unit configured as described above operates as follows. The bill 6 is transported through the transport path 7 and reaches the contact point of the arc portion between the gap 1 a of the magnetic sensor 1 of the magnetic reading unit and the pressing member 50. In the subsequent passage (reading), since the corner of the pressing member 50 in the direction perpendicular to the conveyance direction of the bill 6 is formed in an R shape, the magnetic reading is performed in the direction perpendicular to the direction in which the bill 6 is conveyed. The pressing member is in close contact with the gap portion 1a (width) of the magnetic sensor to be performed without any gap, thereby stabilizing the magnetic output.
[0027]
【The invention's effect】
As described above, according to the present invention, since the guides 22 and 23 are provided at both ends of the pad 21 of the pressing member 20 with a material that is less likely to be worn than the pad 21 such as metal, The wear due to friction due to subsequent passage (reading) is reduced, and the stick-slip phenomenon is not caused.
[0028]
Further, since the ribs 31 and 32 are provided on the frame 30 with a material that is less likely to be worn than the pressing member 2, such as metal, wear due to impact due to collision and friction due to subsequent passage (reading) is reduced. Slip phenomenon no longer occurs.
[0029]
Further, the position of the collision of the pressing member 40 with the bill 6 is shifted from the position of the gap 1a of the magnetic sensor 1 to reduce the wear of the position of the gap 1a of the magnetic sensor 1 due to the collision, thereby causing a stick-slip phenomenon. Is gone.
[0030]
Moreover, since the angle | corner of the orthogonal | vertical direction with respect to the conveyance direction of the banknote 6 of the press member 50 is formed in R shape, it is the gap part 1a of the magnetic sensor which performs a magnetic reading in the direction orthogonal to the direction in which the banknote 6 is conveyed. The pressing member 50 adheres to the (width) without any gap, thereby stabilizing the magnetic output.
