解決しようとする問題点は、カ−ド走行方向に複数の磁気ヘッドが配置されて いる場合に、従来の曲率半径では、カ−ド再生時に、カ−ド突入時のカ−ドス ピ−ド変化により、ジッタ−不良が発生する。ヘッド摩耗寿命が短いことであ る。 The problem to be solved is that, when a plurality of magnetic heads are arranged in the card running direction, the conventional radius of curvature causes the card speed at the time of card inrush during card reproduction. The change causes a jitter defect. The head wear life is short.
【０００４】 本考案の目的は上記欠点に鑑み、カ−ド突入時のカ−ドスピ−ドが安定して、 再生信号にエラ−がなくなり、ヘッド摩耗寿命が長くなり、ディプス長を小さく することが可能になって磁気ヘッドの感度が向上する磁気カ−ドリ−ダ用磁気ヘ ッドを提案することである。In view of the above-mentioned drawbacks, an object of the present invention is to stabilize the card speed at the time of card entry, eliminate errors in reproduced signals, prolong head wear life, and reduce the depth length. It is possible to propose a magnetic head for a magnetic card reader that can improve the sensitivity of the magnetic head.

【０００８】 磁気ヘッド１はコ字形のコア２、３がギャップ部ａで接合されて上部に磁気カ −ド10との摺接部1aが形成され、コア２、３の他側にコイル11が巻回されている 。コア２、３は図示しないホルダ−等で保持されてシ−ルドケ−ス４の中に収容 されて合成樹脂12で固定されている。 コア２、３はコ字形に形成されて上部2a、3aのギャップ部ａのディプス長Ｄは 例えば0.25ｍｍ以下に形成されている。 磁気カ−ド10の先端と当接する摺接部1aの曲率半径はＲ1 ≧１８ｍｍに形成さ れている。 シ−ルドケ−ス４の上部の摺接部4aの曲率半径Ｒ2 はＲ1 より小さく摺接部1a と連続するように形成されている。 磁気カ−ド10の先端と当接する磁気ヘッド１の範囲ｂは、ギャップ部ａを中心 として左右の夫々ギャップ部ａから摺接部1aとしている。In the magnetic head 1, U-shaped cores 2 and 3 are joined at a gap portion a to form a sliding contact portion 1 a with a magnetic card 10 at an upper portion, and a coil 11 is provided on the other side of the cores 2 and 3. It is wound. The cores 2 and 3 are held by a holder or the like (not shown), housed in a shield case 4 and fixed with a synthetic resin 12. The cores 2 and 3 are formed in a U shape, and the depth D of the gap portion a of the upper portions 2a and 3a is formed to be 0.25 mm or less, for example. The radius of curvature of the sliding contact portion 1a that abuts the tip of the magnetic card 10 is formed to be R 1 ≧ 18 mm. The radius of curvature R 2 of the sliding contact portion 4a at the upper portion of the shield case 4 is smaller than R 1 and is formed so as to be continuous with the sliding contact portion 1a. The range b of the magnetic head 1 that abuts on the tip of the magnetic card 10 is centered on the gap portion a and is the sliding contact portion 1a from the left and right gap portions a.
【０００９】 磁気ヘッド１が組み込まれるカ−ドリ−ダは、カ−ド通路が他側の側板５にビ ス13で固定された上側のガイド部６、７、８と下側のガイド部14、15、16とを上 下面として構成され、カ−ド通路の両側は他側の側板５と一側の下側の側板９で 構成されている。 下側の側板９は、他側の側板５に一端が固定された複数本の支柱17の先端に下 側の側板９の複数の透孔9aが挿入されてネジ付ツマミ18で着脱自在に取り付けら れている。 更に一側の側板は上記下側の側板９と上側の側板19で構成され、上側の側板19 は他側の側板５に複数本の支柱20で固定されている。The card reader in which the magnetic head 1 is incorporated has an upper guide portion 6, 7, 8 whose card passage is fixed to the side plate 5 on the other side with a screw 13 and a lower guide portion 14. , 15, 16 are formed as upper and lower surfaces, and both sides of the card passage are formed by the side plate 5 on the other side and the side plate 9 on the lower side of one side. The lower side plate 9 is detachably attached with a screw knob 18 by inserting a plurality of through holes 9a of the lower side plate 9 into the tips of a plurality of columns 17 having one end fixed to the other side plate 5. It is included. Further, the one side plate is composed of the lower side plate 9 and the upper side plate 19, and the upper side plate 19 is fixed to the other side plate 5 by a plurality of columns 20.
【００１０】 磁気ヘッド１は他側の側板５に取り付けられ、カ−ド10を磁気ヘッド１に押圧 するパットロ−ラを兼ねる駆動ロ−ラ21の軸22は他側の側板５と上側の側板19に 軸承されている。 上側のガイド部６の一側には２ケ所に下側の側板９に当たって側板９の位置を 決める突起6aが設けられている。 更に上側のガイド部６、７、８には透孔6b、7a、8aが穿設されてカ−ド通路内 のカ−ド10が覗けるようになってカ−ド10の位置が確認出来る。The magnetic head 1 is attached to the side plate 5 on the other side, and the shaft 22 of the drive roller 21 which also functions as a patroller for pressing the card 10 against the magnetic head 1 has the side plate 5 on the other side and the side plate on the upper side. It is supported by 19. Two protrusions 6a are provided on one side of the upper guide portion 6 to contact the lower side plate 9 and determine the position of the side plate 9. Further, through holes 6b, 7a, 8a are formed in the upper guide portions 6, 7, 8 so that the card 10 in the card passage can be seen and the position of the card 10 can be confirmed.
【００１１】 磁気カ−ドリ−ダの挿入口Ａから磁気カ−ド10が挿入されると、磁気カ−ド10 はパットロ−ラ21で他側の側板５に摺接されながら磁気ヘッド１側へ走行されて 磁気カ−ド10のストライプに情報の記録或は再生が行われる。 この時磁気カ−ド10の先端が磁気ヘッド１の摺接部1aに当接しても、摺接部1a の曲率半径はＲ1 ≧１８ｍｍに形成されているから、滑らかに当たって送られる 。 磁気カ−ド10の先端の当接する範囲は、変形した磁気カ−ド程広くなり、磁気 カ−ド10の先端と当接する磁気ヘッド１の範囲ｂ内の摺接部1aに摺接される。When the magnetic card 10 is inserted from the insertion port A of the magnetic card reader, the magnetic card 10 is slidably contacted by the pad roller 21 to the side plate 5 on the other side and the magnetic head 1 side. Information is recorded or reproduced on the stripe of the magnetic card 10. At this time, even if the tip of the magnetic card 10 comes into contact with the sliding contact portion 1a of the magnetic head 1, since the radius of curvature of the sliding contact portion 1a is formed to be R 1 ≧ 18 mm, the sliding contact portion 1a is smoothly hit. The range of contact of the tip of the magnetic card 10 becomes wider as the deformed magnetic card becomes slidably contacted with the sliding contact portion 1a in the range b of the magnetic head 1 which contacts the tip of the magnetic card 10. .
【００１２】 上記のように磁気カ−ドリ−ダ用磁気ヘッドが構成されると、磁気カ−ド10の 先端が磁気ヘッド１の摺接部1aに当接しても、摺接部1aの曲率半径は従来より大 きいＲ1 ≧１８ｍｍに形成されているから、滑らかに当たって送られて衝撃が小 さくなって、カ−ドスピ−ド変化が極小に出来る。 更にギャップ部ａのディプス長Ｄは例えば0.25ｍｍ以下に形成されているから 、オ−バライト特性が改良される。かつ小電流の記録電流において、磁気ヘッド が機能して磁気ヘッドの感度が向上する。 又、磁気カ−ド10の先端は摺接部1aに緩く当接されるから、ヘッド摩耗寿命が 長くなる。When the magnetic head for a magnetic card reader is configured as described above, even if the tip of the magnetic card 10 contacts the sliding contact portion 1a of the magnetic head 1, the curvature of the sliding contact portion 1a Since the radius is larger than the conventional one, R 1 ≧ 18 mm, it is sent by hitting smoothly and the impact is small, and the card speed change can be minimized. Further, since the depth length D of the gap portion a is formed to be 0.25 mm or less, the overwrite characteristic is improved. Moreover, at a small recording current, the magnetic head functions to improve the sensitivity of the magnetic head. Moreover, since the tip of the magnetic card 10 is loosely contacted with the sliding contact portion 1a, the head wear life is extended.
【００１３】[0013]
本考案は上述のように、磁気カ−ドの先端が磁気ヘッドの摺接部に当接しても 、摺接部の曲率半径は従来より大きい１８ｍｍ以上に形成されているから、滑ら かに当たって送られて衝撃が小さくなって、カ−ドスピ−ド変化が極小に出来る ので、スム−ズなカ−ド走行が出来て良好なエラ−のない記録、再生が出来る。 更にギャップ部のディプス長は薄くなるから、オ−バライト特性が改良される。 かつ小電流の記録電流において、磁気ヘッドが機能して磁気ヘッドの感度が向上 する。又、ヘッド摩耗寿命が長くなる等実用上優れた効果を奏する磁気カ−ドリ −ダ用磁気ヘッドを提供することが出来る。 As described above, according to the present invention, even if the tip of the magnetic card comes into contact with the sliding contact portion of the magnetic head, the radius of curvature of the sliding contact portion is formed to be 18 mm or more, which is larger than that of the prior art, so that the sliding contact portion can be smoothly fed. Since the impact is reduced and the card speed change can be minimized, smooth card running can be performed and good error-free recording and reproducing can be performed. Further, since the depth length of the gap portion becomes thin, the overwrite characteristic is improved. Moreover, at a small recording current, the magnetic head functions to improve the sensitivity of the magnetic head. Further, it is possible to provide a magnetic head for a magnetic card reader, which has a practically excellent effect such as a long head wear life.
