Description

媒体搬送装置Medium transport device
　本発明は、媒体搬送装置に関する。 The present invention relates to a medium conveying apparatus.
　磁気カード及びＩＣカードの処理装置においては、ドライブローラ及び、アイドラローラでカードの幅方向の中央部付近を挟持して搬送する機構をもつものが実用に供されている。一般的にドライブローラは、カードとの摩擦係数が大きくかつアイドラローラからの強い押圧に対する変形を適度に抑える必要があるため、材料に高硬度のゴムが使用される。アイドラローラは、カード表面に傷を付けない目的のためにゴム又は、プラスチックなどの材質が使用される。 Magnetic card and IC card processing apparatuses are in practical use having a mechanism that sandwiches and conveys the vicinity of the center in the width direction of the card with a drive roller and an idler roller. Generally, the drive roller has a large coefficient of friction with the card and needs to moderately suppress deformation against strong pressing from the idler roller, and therefore, a hard rubber is used as a material. The idler roller is made of a material such as rubber or plastic for the purpose of not scratching the card surface.
　ローラ部へのカードの突入あるいはローラ部からのカードの離脱時のカードの速度変動を小さくするために、ドライブローラ及び、アイドラローラは下記３種類の構成となっているものが一般的である。
  （１）ドライブローラ及びアイドラローラの間にあらかじめカードの厚さよりも少し小さい隙間を設ける。
  （２）カード挿入前の状態で、ドライブローラとアイドラローラとを当接させておく構成であるが、アイドラローラからの押圧を、隙間がゼロからカードの厚み付近までの状態では弱く、隙間がカードの厚み付近以上になった状態では強くなる様、２段階に切替える。
  （３）ドライブローラ及びアイドラローラの間にあらかじめカードの厚さよりも少し小さい隙間を設け、アイドラローラ側にアイドラローラよりも外径が大きく、アイドラローラよりも低い硬度の薄カード搬送用のアイドラローラを設置する。 In order to reduce the speed fluctuation of the card when the card enters the roller part or the card is removed from the roller part, the drive roller and the idler roller generally have the following three types of configurations.
(1) A gap slightly smaller than the card thickness is provided in advance between the drive roller and idler roller.
(2) The drive roller and the idler roller are in contact with each other before the card is inserted, but the pressure from the idler roller is weak when the gap is from zero to near the thickness of the card, and the gap is Switch to 2 steps so that it becomes stronger when the card is near the thickness of the card.
(3) A gap slightly smaller than the card thickness is provided between the drive roller and the idler roller in advance, and the idler roller for carrying a thin card having a larger outer diameter than the idler roller on the idler roller side and lower hardness than the idler roller. Is installed.
　なお、上記（３）は、上記（１）の基本構成であって、薄いカード又は、レシートなどの薄い異物を搬送することが出来るように改善した構成である。 The above (3) is the basic configuration of the above (1), and is an improved configuration so that a thin foreign object such as a thin card or a receipt can be conveyed.
　また、本発明の背景技術として、特開平７－１０３１３号公報がある。この公報には、「２段バネ機構による安定した搬送力を常に維持することが可能で、しかも安価で取り扱いも容易な媒体搬送ローラ機構を実現する」と記載されている。なお特開平７－１０３１３の構成は、上記（２）の構成にあたる。 Also, as a background art of the present invention, there is JP-A-7-10313. This publication describes that “a medium transport roller mechanism that can always maintain a stable transport force by a two-stage spring mechanism, and that is inexpensive and easy to handle” is realized. The configuration of JP-A-7-10313 corresponds to the configuration of (2) above.
特開平７-１０３１３JP 7-10313 A
　上記（１）の構成の場合、誤って挿入されたその隙間より薄いカード又は、レシートなどの薄い異物を搬送して排出することができない。 In the case of the above configuration (1), it is not possible to transport and discharge a card or a thin foreign object such as a receipt that is thinner than the gap inserted by mistake.
　上記（２）の構成（特許文献１の構成）の場合、薄いカード又は、レシートなどの薄い異物を搬送することが可能であるが、押圧を２段階に切替える機構が複雑になる。 In the case of the above configuration (2) (the configuration of Patent Document 1), it is possible to transport a thin foreign object such as a thin card or a receipt, but the mechanism for switching the pressing in two stages becomes complicated.
　また、上記（１）（２）の構成共に、カードの搬送を確実にする目的及び、カード表面に傷を付けない目的のために、ドライブローラの材質は硬質ゴムであり、アイドラローラの材質もゴム又は、プラスチックなどの材質を選択せざるを得ない。その結果としてカードに接触しているローラが電気抵抗の大きな材料になり、カードに帯電した静電気を効率よく放電させることが困難であり、カード６に帯電した静電気がＩＣカード処理部で放電されることにより、カード処理装置の電気回路が故障する又は、異常動作をする。 In addition, in both the configurations (1) and (2), the drive roller is made of hard rubber and the idler roller is made of a material for the purpose of ensuring the card transport and not scratching the card surface. A material such as rubber or plastic must be selected. As a result, the roller in contact with the card becomes a material having a large electric resistance, and it is difficult to efficiently discharge the static electricity charged on the card, and the static electricity charged on the card 6 is discharged by the IC card processing unit. As a result, the electric circuit of the card processing device fails or operates abnormally.
　上記（３）の構成では、カード処理装置の基本機能である、磁気カードデータの読み取り及び書き込み機能の性能に悪影響を及ぼさないために、薄カード搬送用のアイドラローラの材質を軟らかいゴム又は、スポンジなどにする必要がある。そのため薄カード搬送用のローラは、軟らかい素材に対して大変形を強いられることになり、耐磨耗性及び耐候性を確保することが困難で、素材が磨耗及び、劣化し易い。 In the configuration (3), the idler roller for carrying the thin card is made of a soft rubber or sponge so as not to adversely affect the performance of the magnetic card data reading and writing function, which is the basic function of the card processing device. It is necessary to make it. For this reason, the roller for carrying a thin card is forced to undergo a large deformation with respect to a soft material, and it is difficult to ensure wear resistance and weather resistance, and the material is easily worn and deteriorated.
　そこで本発明は、カードをドライブローラ及びアイドラローラで挟持して搬送する装置において、誤って挿入された、正規のカードよりも薄いカードやレシートなどの薄い異物を搬送して返却するための単純でかつ耐久性の良いカード搬送装置を提供する。 Therefore, the present invention is a simple device for transporting and returning a thin foreign object such as a card or a receipt thinner than a regular card, which is erroneously inserted, in a device that sandwiches and transports the card between a drive roller and an idler roller. A highly durable card transport device is provided.
　上記課題を解決するために、本願はその解決手段を複数含んでいるが、例えば特許請求の範囲に記載の構成を採用する。それは、第１の媒体搬送部と第２の媒体搬送部と第３の媒体搬送部とを備えた媒体搬送装置であって、前記第１の媒体搬送部と前記第２の媒体搬送部および前記第３の媒体搬送部は、前記媒体を搬送する搬送路を挟み対向する位置に並べて設置され、前記第１の媒体搬送部の前記媒体接触面と前記第３の媒体搬送部の前記媒体接触面との間の距離は、前記第１の媒体搬送部の前記媒体接触面と前記第２の媒体搬送部の前記媒体接触面との間の距離に比べ短く設置され、前記第３の媒体搬送部は、前記第２の媒体搬送部よりも高い硬度を有する螺旋状の部材より構成され、前記部材は前記螺旋の回転軸の垂直方向の弾性力を備える媒体搬送装置である。 In order to solve the above-mentioned problems, the present application includes a plurality of means for solving the problems. For example, the configuration described in the claims is adopted. It is a medium conveying apparatus comprising a first medium conveying unit, a second medium conveying unit, and a third medium conveying unit, wherein the first medium conveying unit, the second medium conveying unit, The third medium transport unit is installed side by side at positions facing each other across the transport path for transporting the medium, and the medium contact surface of the first medium transport unit and the medium contact surface of the third medium transport unit Is set shorter than the distance between the medium contact surface of the first medium transport unit and the medium contact surface of the second medium transport unit, and the third medium transport unit Is composed of a spiral member having a hardness higher than that of the second medium transport unit, and the member is a medium transport device having an elastic force in a direction perpendicular to the rotation axis of the spiral.
　本発明のカード搬送装置では、アイドラローラの近くに、その外径よりも大きな外径のコイルバネを同軸上に設置する構成としたので、カードが挿入される前の状態でドライブローラとアイドラローラとの間に隙間を設ける構成においても、誤って挿入されたその隙間より薄いカード又は、レシートなどの薄い異物を搬送して排出することが可能である。　また、コイルバネの半径方向のたわみ力で薄いカード又は、レシートなどをドライブローラ側に付勢する構成としたので、アイドラローラの軸にコイルバネを取り付けるだけでその装置を実現できるため、単純で安価な構成にすることが可能である。 In the card conveying device of the present invention, since the coil spring having an outer diameter larger than the outer diameter is coaxially installed near the idler roller, the drive roller and the idler roller are in a state before the card is inserted. Even in the configuration in which a gap is provided between the two, it is possible to transport and discharge a card or a thin foreign object such as a receipt that is thinner than the gap that is erroneously inserted. In addition, since the thin card or receipt is urged toward the drive roller by the bending force of the coil spring in the radial direction, the device can be realized simply by attaching the coil spring to the shaft of the idler roller. It is possible to configure.
　また、ステンレスのバネ用鋼材などの金属をコイルバネの材料に使うことができるため、（１）カードに帯電した静電気を効率よく接地線に逃がす構成が可能となる、（２）ゴムやスポンジなどの材料を使う構成と比較して耐久性及び、耐候性を向上することが出来るという効果がある。 In addition, since metal such as stainless steel for springs can be used for the coil spring material, (1) it is possible to efficiently discharge the static electricity charged to the card to the ground wire, and (2) rubber, sponge, etc. There is an effect that durability and weather resistance can be improved as compared with a configuration using a material.

　以下、実施例を図面を用いて説明する。 Hereinafter, examples will be described with reference to the drawings.
  本実施例の説明を行う前に、従来技術について図１～図４、図１２、１３図を用いて説明をする。図１２は、カード６をドライブローラとアイドラローラに挟持して搬送する方式の一般的なカード処理装置の側面図である。ドライブローラとアイドラローラの対は、２組から４組をカード進行方向に配置する。図１２では、カード挿入口７の直後に第１ローラ対（ドライブローラ３及びアイドラローラ４）と、磁気ヘッド２１の直後に第２ローラ対（ドライブローラ１８及びアイドラローラ１９）の２組のローラ対を搬送機構として構成した例を示している。一般的なカード処理装置の場合、第１ローラ対と第２ローラ対との距離はカード６の長手方向の長さより小さく設定されている。 従 来 Prior to describing this embodiment, the prior art will be described with reference to FIGS. 1 to 4, 12, and 13. FIG. 12 is a side view of a general card processing apparatus in which the card 6 is conveyed while being sandwiched between a drive roller and an idler roller. Two to four pairs of drive rollers and idler rollers are arranged in the card traveling direction. In FIG. 12, two sets of rollers, a first roller pair (drive roller 3 and idler roller 4) immediately after the card insertion slot 7 and a second roller pair (drive roller 18 and idler roller 19) immediately after the magnetic head 21. The example which comprised the pair as a conveyance mechanism is shown. In the case of a general card processing apparatus, the distance between the first roller pair and the second roller pair is set smaller than the length of the card 6 in the longitudinal direction.
　カード６に書き込まれている磁気データを読取る場合及び、カード６に磁気データを書き込む場合には、カード６の搬送速度の変動を出来るだけ少なくする必要がある。そのためカード６挿入前の状態では、アイドラローラとドライブローラとは当接させないで、カード６の厚みよりも少し小さい隙間（ローラギャップ）を設ける。 When reading the magnetic data written on the card 6 and writing the magnetic data on the card 6, it is necessary to reduce the fluctuation in the transport speed of the card 6 as much as possible. Therefore, in a state before the card 6 is inserted, the idler roller and the drive roller are not brought into contact with each other, and a gap (roller gap) slightly smaller than the thickness of the card 6 is provided.
　このローラギャップについて、図１～図４、図１３を用いて詳細に説明する。図１～図３は一般的なカード処理装置の第１ローラ対近傍の拡大図である。図１（ａ）、図２（ａ）、図３（ａ）は一般的なカード処理装置の第１ローラ対近傍の正面図である。図１（ｂ）、図２（ｂ）、図３（ｂ）は、一般的なカード処理装置の第１ローラ対近傍の側面図である。図４は第１アイドラローラ４の拡大した断面図であり、図１３に示す軸２７部分を切断した場合を示している。以後、断面図については図１３の軸２７部分について切断した面を表すものとする。 The roller gap will be described in detail with reference to FIGS. 1 to 4 and FIG. 1 to 3 are enlarged views of the vicinity of a first roller pair of a general card processing apparatus. FIG. 1A, FIG. 2A, and FIG. 3A are front views of the vicinity of a first roller pair of a general card processing apparatus. FIG. 1B, FIG. 2B, and FIG. 3B are side views of the vicinity of a first roller pair of a general card processing apparatus. FIG. 4 is an enlarged sectional view of the first idler roller 4 and shows a case where the shaft 27 portion shown in FIG. 13 is cut. Hereinafter, the cross-sectional view represents a surface cut along the shaft 27 portion of FIG.
　図１（ａ）に示すように、第１のローラ対を構成する第１ドライブローラ３と第１アイドラローラ４との間にカード６の厚みよりも少し小さい隙間（ローラギャップ）を設けている。また図２（ｂ）に示すように、カード挿入時には、カード６により第１アイドラローラレバー９及び、アイドラローラ押圧バネ８が押圧され、カード６は第１ドライブローラ３と第１アイドラローラ４により安定して挟持される。 As shown in FIG. 1A, a gap (roller gap) slightly smaller than the thickness of the card 6 is provided between the first drive roller 3 and the first idler roller 4 constituting the first roller pair. . 2B, when the card is inserted, the first idler roller lever 9 and the idler roller pressing spring 8 are pressed by the card 6, and the card 6 is pressed by the first drive roller 3 and the first idler roller 4. It is clamped stably.
　このような構成にすることよって、カード６の先端がローラ対に突入する場合の搬送速度の急激な減少及び、カード６の後端がカード対から排出される場合の急激な搬送速度の増加を低減することが出来る。なお、第1アイドラローラ４は図４に示すように、アイドラローラ軸１３、アイドラローラ芯金１２、アイドラローラ用ベアリング１１から構成されている。 With such a configuration, a rapid decrease in the conveyance speed when the leading edge of the card 6 enters the roller pair and a rapid increase in the conveyance speed when the trailing edge of the card 6 is ejected from the card pair are achieved. It can be reduced. As shown in FIG. 4, the first idler roller 4 includes an idler roller shaft 13, an idler roller core 12, and an idler roller bearing 11.
　また、第１アイドラローラ４の近くに、その外径よりも大きな外径の薄カード搬送用アイドラローラ５を第１アイドラローラ４の軸と同軸上に設置されている。カード６よりも薄いカード１０が挿入された場合や、レシートなどの薄い異物が挿入された場合、図３（ａ）に示すように、薄カード搬送用アイドラローラ５により第１ドライブローラ３と当接することで薄いカード１０等を搬送できる。 Also, near the first idler roller 4, a thin card carrying idler roller 5 having an outer diameter larger than the outer diameter is installed coaxially with the axis of the first idler roller 4. When a card 10 thinner than the card 6 is inserted, or when a thin foreign object such as a receipt is inserted, as shown in FIG. A thin card 10 or the like can be conveyed by touching.
　しかし、薄カード搬送用アイドラローラ５は第１アイドラローラ４よりも外径が大きいため、通常のカード６の搬送に影響を与えないようにするためにローラの材質を軟らかいゴム又は、スポンジなどにする必要がある。そのため薄カード搬送用のローラは、通常のカードを搬送する場合は大変形を強いられることになり、耐磨耗性及び耐候性を確保することが困難で、素材が磨耗及び、劣化し易い。 However, since the idler roller 5 for carrying a thin card has a larger outer diameter than the first idler roller 4, the roller material is made of soft rubber or sponge so as not to affect the normal card 6 conveyance. There is a need to. Therefore, the roller for carrying a thin card is forced to undergo a large deformation when carrying a normal card, and it is difficult to ensure wear resistance and weather resistance, and the material is easily worn and deteriorated.
　なお、磁気カードとＩＣカードの両方を処理するタイプのカード処理機の場合は、カード６の搬送路の途中又は、後端部にＩＣカードの接点にカード処理機の接点を接続するための、ＩＣカード処理部１７を設置する構成となっている。 In the case of a card processing machine of a type that processes both magnetic cards and IC cards, in order to connect the contacts of the card processing machine to the contacts of the IC card in the middle of the conveyance path of the card 6 or at the rear end, The IC card processing unit 17 is installed.
　次に、本実施例について図面を用いて説明する。
  図５は、本実施例の断面図である。なお、基本的な構成は一般的なカード処理装置と同様であるため説明は省略する。また、図５は第１のローラ対を図１３に示す断面軸２７で切断し、カード挿入口から見た場合の図を表している。 Next, the present embodiment will be described with reference to the drawings.
FIG. 5 is a cross-sectional view of the present embodiment. Since the basic configuration is the same as that of a general card processing apparatus, description thereof is omitted. FIG. 5 shows the first roller pair cut along the cross-sectional shaft 27 shown in FIG. 13 and viewed from the card insertion slot.
　本実施例では第１アイドラローラ４の近くに、その外径よりも大きな外径の金属線を螺旋状にしたコイルバネ１４を第１アイドラローラ４の軸と同軸上に設置する構成としている。図５はカード６を挿入しているが、カード６の挿入前の状態では図１（ａ）と同様に第１ドライブローラ３と第１アイドラローラ４の間にはカード６の厚みよりもわずかに小さい隙間が確保されている。 In this embodiment, a coil spring 14 in which a metal wire having an outer diameter larger than the outer diameter is spirally installed near the first idler roller 4 and coaxial with the axis of the first idler roller 4 is installed. In FIG. 5, the card 6 is inserted, but in the state before the card 6 is inserted, the thickness between the first drive roller 3 and the first idler roller 4 is slightly smaller than the thickness of the card 6 as in FIG. A small gap is secured.
　カード６がカード挿入口から挿入された後に第１ドライブローラ３と第１アイドラローラ４に挟持された時、コイルバネ１４の外周部分は螺旋の半径方向に撓んで、第１アイドラローラ４と同じ高さになる。ただしコイルバネ１４をその高さまで撓ませる力は、第１アイドラローラ４を第１ドライブローラ３側に当接させる力よりも十分弱く設定している。 When the card 6 is sandwiched between the first drive roller 3 and the first idler roller 4 after being inserted from the card insertion slot, the outer peripheral portion of the coil spring 14 bends in the radial direction of the spiral, and is the same height as the first idler roller 4. It will be. However, the force for bending the coil spring 14 to its height is set to be sufficiently weaker than the force for bringing the first idler roller 4 into contact with the first drive roller 3 side.
　そのため、カード６がコイルバネ１４から受ける力は、カード６を第１ドライブローラ３と第１アイドラローラ４の間に挟持して搬送する時のカード搬送速度に対しての影響が無視できるほどに小さい。したがって、このコイルバネ１４がカード６に及ぼす力はカード処理装置の基本性能である磁気カードデータの読取り性能及び、書込み性能に影響を及ぼさない。 Therefore, the force that the card 6 receives from the coil spring 14 is so small that the influence on the card conveyance speed when the card 6 is conveyed while being sandwiched between the first drive roller 3 and the first idler roller 4 can be ignored. . Therefore, the force that the coil spring 14 exerts on the card 6 does not affect the reading performance and writing performance of the magnetic card data, which is the basic performance of the card processing apparatus.
　図６は、薄いカード１０又は、レシートなどの薄い異物が挿入された場合のカード処理装置の断面図を表している。第１ドライブローラ３と第１アイドラローラ４の間にはカード６の厚みよりもわずかに小さい隙間が確保されている。薄いカード１０又は、レシートなどの薄い異物はコイルバネ１４から垂直方向の力を受け、第１ドライブローラ３に当接し、第１ドライブローラとの摩擦力で搬送される。 FIG. 6 shows a cross-sectional view of the card processing apparatus when a thin card 10 or a thin foreign object such as a receipt is inserted. A gap slightly smaller than the thickness of the card 6 is secured between the first drive roller 3 and the first idler roller 4. A thin foreign object such as a thin card 10 or a receipt receives a vertical force from the coil spring 14, contacts the first drive roller 3, and is conveyed by a frictional force with the first drive roller.
　図７はコイルバネ１４を第１アイドラローラ４と同軸上に取付けた状態の断面図（図７（ａ））及び、コイルバネ１４単独の詳細図（図７（ｂ））である。コイルバネ１４は、開始部分１４ａ及び、終端部分１４ｂとその途中の円筒形状の部分でその外径を変えている。なお、このような異形状のコイルバネは、通常の円筒形状のコイルバネを製造するものと同じフォーミング設備で容易に製作できるため、寸法の安定した部品を安価に製作できる。 FIG. 7 is a cross-sectional view (FIG. 7A) in a state where the coil spring 14 is mounted coaxially with the first idler roller 4, and a detailed view of the coil spring 14 alone (FIG. 7B). The outer diameter of the coil spring 14 is changed at the start portion 14a, the end portion 14b, and the cylindrical portion in the middle thereof. In addition, since such an unusually shaped coil spring can be easily manufactured by the same forming equipment as that for manufacturing a normal cylindrical coil spring, a component having a stable dimension can be manufactured at low cost.
　コイルバネ１４の開始部分１４ａ及び、終端部分１４ｂの内径は、アイドラローラの芯金１２のコイルバネ取付け部分のフランジ部の外径よりもわずかに小さく設定している。コイルバネ１４を第１アイドラローラ４に取り付ける場合には、コイルバネ１４の開始部分１４ａ及び、終端部分１４ｂを押し広げて、アイドラローラの芯金１２のフランジを乗り越えさせ、スラスト方向（アイドラローラ軸１３の軸方向）の位置を固定する。 The inner diameter of the start portion 14a and the end portion 14b of the coil spring 14 is set to be slightly smaller than the outer diameter of the flange portion of the coil spring mounting portion of the core metal 12 of the idler roller. When the coil spring 14 is attached to the first idler roller 4, the start portion 14 a and the end portion 14 b of the coil spring 14 are pushed and spread over the flange of the core metal 12 of the idler roller, and the thrust direction (the idler roller shaft 13 Axial position is fixed.
　通常の動作では、コイルバネ１４の開始部分１４ａや終端部分１４ｂにアイドラローラの芯金１２のフランジ部を越えるようにを押し広げる力は加わらないため、コイルバネ１４を固定することができる。 In the normal operation, the coil spring 14 can be fixed because no force is applied to the start portion 14a and the end portion 14b of the coil spring 14 so as to push the flange portion of the core metal 12 of the idler roller.
　上記の構成の結果、従来のドライブローラ及び、アイドラローラでカードを挟持して搬送する構成のカード処理機では、カード６の搬送速度の変動を少なくするために、（１）カード挿入前の状態でドライブローラとアイドラローラとの間に予めカードの厚みより小さい隙間を設ける必要があるために、薄いカード１０又は、レシートなどの薄い異物が挿入された場合に、それが搬送出来ずに、カード処理機内部に残留して以後の取引が出来なくなるという課題、（２）ドライブローラとアイドラローラとを予め当接させておく構成にする場合、誤って挿入された薄いカード１０又は、レシートなどの薄い異物を搬送することが可能であるが、アイドラローラの押圧を２段階に切替えるための機構が複雑になるという課題が解決され、カード６の搬送速度の変動を少なくする構成と、薄いカード１０又は、レシートなどの薄い異物を搬送することが出来るという構成とを最小の部品数での単純で安価な構成で両立することが可能になった。 As a result of the above configuration, in the card processing machine configured to sandwich and convey the card with the conventional drive roller and idler roller, in order to reduce fluctuations in the conveyance speed of the card 6, (1) the state before the card insertion In this case, it is necessary to provide a gap smaller than the thickness of the card in advance between the drive roller and the idler roller. Therefore, when a thin card 10 or a thin foreign object such as a receipt is inserted, the card cannot be conveyed. Issues that remain inside the processing machine and prevent future transactions, (2) When the drive roller and idler roller are in contact with each other in advance, such as a thin card 10 that has been mistakenly inserted or a receipt Although it is possible to transport thin foreign objects, the problem that the mechanism for switching the pressure of the idler roller in two stages is complicated is solved. It is possible to achieve both a configuration that reduces the variation in the conveyance speed of 6 and a configuration that can convey a thin foreign object such as a thin card 10 or a receipt with a simple and inexpensive configuration with a minimum number of parts. became.
　また、本実施例ではステンレスのバネ用鋼材などの金属をコイルバネ１４の材料に使うことができるため、ゴムやスポンジなどの材料を使う従来の構成と比較して、耐久性及び耐候性を向上することが出来るという効果がある。なお、コイルバネ１４の材料は金属に限定されるものではなく、耐久性や対候性を有する素材（例えばプラスチックなどの合成樹脂）であれば適用可能である。 Further, in the present embodiment, a metal such as a stainless steel spring material can be used as the material of the coil spring 14, so that the durability and weather resistance are improved as compared with the conventional configuration using a material such as rubber or sponge. There is an effect that can be. The material of the coil spring 14 is not limited to metal, and any material having durability or weather resistance (for example, synthetic resin such as plastic) can be applied.
　［変形例］
  実施例１の変形例として、次の構成が考えられる。図６は、実施例１の変形例であり、コイルバネ１４の素材２５の表面に樹脂２６（例えばエラストマー）等のコイルバネ１４よりも柔軟な素材を被膜材とする薄い層を構成したものを示している。 [Modification]
As a modification of the first embodiment, the following configuration can be considered. FIG. 6 shows a modification of the first embodiment, in which a thin layer is formed on the surface of the material 25 of the coil spring 14 using a material more flexible than the coil spring 14 such as resin 26 (for example, elastomer) as a coating material. Yes.
　バネ素材２５の表面を樹脂２６コーティング（被膜処理）することにより、金属がカード表面に直接触れないようにすることが出来るため、カード表面に傷が付きづらくなる。なお、樹脂２６に限定せずバネ素材２５を覆い、カードの表面の傷付を防止する機構であれば適応可能であることは言うまでもない。 By coating the surface of the spring material 25 with the resin 26 (coating treatment), it is possible to prevent the metal from directly touching the card surface, so that the card surface is not easily damaged. Needless to say, any mechanism that covers the spring material 25 and prevents the surface of the card from being damaged is not limited to the resin 26.
　図９は、本実施例の詳細を示した図である。上記のコイルバネ１４と同等の機能を実現するために、コイルバネ１４を構成していたバネ用線材の代わりにバネ用鋼帯を使用して薄カード搬送用のバネ帯ローラ２２を構成している。なお、図９（ａ）はバネ帯ローラ２２をアイドラローラの芯金１２に取り付けた場合の断面図であり、図９（ｂ）はバネ帯ローラ２２の側面図である。 FIG. 9 is a diagram showing details of the present embodiment. In order to realize a function equivalent to that of the coil spring 14 described above, a spring belt roller 22 for carrying a thin card is formed by using a steel strip for a spring instead of the wire rod for the spring constituting the coil spring 14. 9A is a cross-sectional view of the spring belt roller 22 attached to the idler roller core 12, and FIG. 9B is a side view of the spring belt roller 22. FIG.
　薄カード搬送用のバネ帯ローラ２２は、固定用の中央部分と、外周部分とで直径を変えている。中央部分から外周部分まで渦巻き状に、一枚のバネ用鋼帯でローラを構成している。バネ帯ローラ２２は、アイドラローラの芯金１２に取り付けられ、固定部材２３（例えばＥリング等）でスラスト方向の位置を固定する。 The diameter of the spring belt roller 22 for carrying a thin card is changed between the central portion for fixing and the outer peripheral portion. A roller is constituted by a single steel strip for a spring in a spiral shape from the central portion to the outer peripheral portion. The spring belt roller 22 is attached to the core metal 12 of the idler roller, and the position in the thrust direction is fixed by a fixing member 23 (for example, an E ring).
　バネに鋼帯を使用したことにより、上記の実施例１のように線材を使用した場合と比較して、カード６とバネ帯ローラとの接触面積が大きくなり、バネ帯ローラがカード表面に傷を付け難くなるという効果がある。 By using a steel strip for the spring, the contact area between the card 6 and the spring belt roller is larger than when a wire is used as in the first embodiment, and the spring belt roller is damaged on the card surface. There is an effect that it becomes difficult to attach.
　また、本実施例２の変形例として、図１０に示すバネ用鋼帯を使用して薄カード搬送用のバネ帯ローラを構成する別の実施例についても挙げられる。なお、図１０（ａ）はバネ帯ローラ２４をアイドラローラの芯金１２に取り付けた場合の断面図であり、図１０（ｂ）はバネ帯ローラ２４の側面図である。 Also, as a modification of the second embodiment, another embodiment in which a spring belt roller for carrying a thin card is configured using the spring steel strip shown in FIG. 10A is a cross-sectional view of the spring belt roller 24 attached to the idler roller core 12, and FIG. 10B is a side view of the spring belt roller 24.
　バネ帯ローラ２４の固定用の中央部分２４ａの幅を外周部分２４ｂよりも細くすることにより、カードと当接する部分の幅を大きくした場合であっても、半径方向の撓み力を上記の図９の構成と比較して自由に弱く設定することができる。したがって、カード処理機の基本機能である、磁気カードデータの読取り及び、書込み機能の性能に悪影響がない構成にすることが出来る。 Even if the width of the portion in contact with the card is increased by making the width of the central portion 24a for fixing the spring belt roller 24 narrower than that of the outer peripheral portion 24b, the bending force in the radial direction can be reduced. Compared with the configuration of, it can be set weakly freely. Therefore, it is possible to adopt a configuration that does not adversely affect the performance of the magnetic card data reading and writing functions, which are basic functions of the card processor.
　なお、本実施例で説明したバネ帯ローラ２２、２４の材料は金属に限定されるものではなく、耐久性や対候性を有する素材（例えばプラスチックなどの合成樹脂）を帯状にしたものであれば適用可能である。 The material of the spring belt rollers 22 and 24 described in the present embodiment is not limited to metal, but may be a belt made of a material having durability or weather resistance (for example, synthetic resin such as plastic). If applicable.
　図１１は、本実施例の詳細を示した図である。図１１（ａ）はカード挿入口から見た本実施例の断面図、図１１（ｂ）は本実施例の側面図である。なお、実施例１と同様の構成については説明を省略する。 FIG. 11 is a diagram showing details of the present embodiment. FIG. 11A is a cross-sectional view of this embodiment viewed from the card insertion slot, and FIG. 11B is a side view of this embodiment. Note that the description of the same configuration as that of the first embodiment is omitted.
　本実施例の説明を行う前に、従来技術について説明する。従来の構成ではカード挿入口から静電気が帯電したカード６が挿入された場合、カード６の搬送を確実にする目的及び、カード表面に傷を付けない目的のために、第１ドライブローラ３の材質は硬質ゴムであり、第１アイドラローラ６の材質もゴム又は、プラスチックなどの材質を選択せざるを得ない。 Prior to describing this embodiment, the prior art will be described. In the conventional configuration, when the card 6 charged with static electricity is inserted from the card insertion slot, the material of the first drive roller 3 is used for the purpose of ensuring the transport of the card 6 and the purpose of not scratching the card surface. Is a hard rubber, and the material of the first idler roller 6 must be a material such as rubber or plastic.
　その結果としてカード６に接触している二つのローラが両方共に電気抵抗の大きな材料にせざるを得ず、カードに帯電した静電気を効率よく放電させることが困難なために、カード６に帯電した静電気がＩＣカード処理部１７で放電され、カード処理装置の電気回路が故障する又は、異常動作をするという問題がある。 As a result, both of the two rollers in contact with the card 6 must be made of a material having a large electric resistance, and it is difficult to efficiently discharge the static electricity charged on the card. Is discharged in the IC card processing unit 17, and the electric circuit of the card processing device breaks down or operates abnormally.
　本実施例では、薄いカード１０又は、レシートなどの薄い異物の搬送用に上記のコイルバネ１４を使う構成であって、図１１に示すようにコイルバネ１４から第１アイドラローラのレバー９及び、電線１６を介して金属フレーム１５まで、電気的に接続させるという構成としている。 In this embodiment, the coil spring 14 is used for transporting a thin foreign object such as a thin card 10 or a receipt. As shown in FIG. 11, the coil spring 14 to the lever 9 of the first idler roller and the electric wire 16 are used. The metal frame 15 is electrically connected through the connector.
　図を用いて本実施例について詳細に説明する。本実施例においては、静電気が帯電したカード６はまず、図１１（ｂ）に示すカード挿入口７の直後にある第１ローラ部分（第１ドライブローラ３及び第１アイドラローラ４）でコイルバネ１４に接触する。コイルバネ１４、アイドラローラのレバー９は材質が金属であるためカード６に蓄積された静電気がコイルバネ１４とレバー９と電線１６を経由して金属フレーム１５に到達し、静電気が放電される。したがってカード６に蓄積された静電気が放電されることで、その後にＩＣカード処理部１７にカード６が搬送されても静電気の放電によるカード処理装置の電気回路の故障又は、異常動作が発生しないという効果がある。 This example will be described in detail with reference to the drawings. In the present embodiment, the statically charged card 6 is firstly coiled at the first roller portion (the first drive roller 3 and the first idler roller 4) immediately after the card insertion slot 7 shown in FIG. To touch. Since the coil spring 14 and the lever 9 of the idler roller are made of metal, static electricity accumulated in the card 6 reaches the metal frame 15 via the coil spring 14, the lever 9 and the electric wire 16, and the static electricity is discharged. Therefore, the static electricity accumulated in the card 6 is discharged, so that even if the card 6 is subsequently transported to the IC card processing unit 17, the failure of the electric circuit of the card processing apparatus due to the electrostatic discharge or the abnormal operation does not occur. effective.
　なお、カード６への静電気の帯電は、上記のようにカード処理装置に挿入される前に発生する場合と、カード６がカード処理装置の内部で前後方向に搬送される途中にカード６とカード処理機のゴムやプラスチックなどの内部部品との摩擦よって発生する場合とがある。内部部品との摩擦よる帯電の場合においても、コイルバネ１４及び接地のための電線を第２ローラ部分（第２ドライブローラ１８及び第２アイドラローラ１９）にも同様に取り付けることにより、その静電気を処理装置の内部で放電させることができるので、カード処理装置の電気回路の故障又は、異常動作が発生しないという効果がある。 Note that the static charge on the card 6 occurs before the card 6 is inserted into the card processing device as described above, and when the card 6 is being transported in the front-rear direction inside the card processing device. It may be caused by friction with internal parts such as rubber or plastic of the processing machine. Even in the case of charging due to friction with internal components, the coil spring 14 and the electric wire for grounding are similarly attached to the second roller portion (the second drive roller 18 and the second idler roller 19) to treat the static electricity. Since the discharge can be performed inside the apparatus, there is an effect that the electric circuit of the card processing apparatus does not fail or does not operate abnormally.
　第３ローラ以降にもローラが構成される場合においても同様に、それぞれのアイドラローラにコイルバネ１４及び接地のための電線を構成すれば静電気による不具合を防ぐことが出来る。また、コイルバネ１４を導電性の樹脂等で被膜処理を行うことにより、導電性と柔軟性を両立させることも可能である。 Similarly, in the case where the rollers are formed after the third roller, similarly, if the coil spring 14 and the electric wire for grounding are formed on each idler roller, it is possible to prevent the trouble due to static electricity. Further, it is possible to achieve both conductivity and flexibility by coating the coil spring 14 with a conductive resin or the like.
