て、その磁気ヘッドにより挿入された磁気カードの磁気
テープに記憶された情報を読み取ったり、または磁気テ
ープに新たな情報を書き込んだりする。This type of magnetic card usually has one strip of magnetic tape embedded in it.
On the other hand, a magnetic card device is equipped with a magnetic head, and the magnetic head reads information stored on the magnetic tape of an inserted magnetic card, or writes new information on the magnetic tape.
この様な磁気カードリーダを第１図に示す。Such a magnetic card reader is shown in FIG.
磁気カードリーダ筐体１０内には駆動モータ１１により

４が平行配置され、一方送りローラ１３には押えローラ
１５が平行配置されかつ磁気ヘッド１６が対向して設け
られる。Inside the magnetic card reader housing 10 are two feed rollers 1 driven by a drive motor 11 via, for example, a belt.
2 and 13 are arranged, and the feed roller 12 has a presser roller 1.
4 are arranged in parallel, and on the other hand, a presser roller 15 is arranged parallel to the feed roller 13, and a magnetic head 16 is provided facing the feed roller 13.
この磁気ヘッド１６は磁気ヘッド取付板１７に固締され
ており、一方このヘッド取付板１１は調節支持板を介し
てレバー１８に装着される。The magnetic head 16 is fixed to a magnetic head mounting plate 17, and the head mounting plate 11 is mounted on a lever 18 via an adjustment support plate.
レバー１８はカードリーダ筐体１０に枢着された枢動ピ

ードリーダ筐体１０との間に設けられたコイルばね２０
によりレバー１８は反時計回りに常時付勢されている。The lever 18 is rotatable with respect to a pivot pin 19 pivotally connected to the card reader housing 10, and further includes a coil spring 20 provided between one end of the lever and the card reader housing 10.
As a result, the lever 18 is constantly biased counterclockwise.
磁気カード２１がカードリーダ筐体１０内に挿入される
と図示しない制御装置により駆動モータ１１が起動して
送りローラ１２，１３が回転し、斯くして磁気カード２
１は送りローラ１２と押えローラ１４間を通って矢印Ａ
の方向に送り込まれる。When the magnetic card 21 is inserted into the card reader housing 10, the drive motor 11 is activated by a control device (not shown) to rotate the feed rollers 12 and 13, and thus the magnetic card 2
1 passes between the feed roller 12 and the presser roller 14 and arrow A
sent in the direction of.
次いで磁気カード２１は送りローラ１３と押えローラ１
５間に侵入してこれらのロー２１３，１５により更に矢
印Ａの方向に送り込ｌれる。Next, the magnetic card 21 is transferred to the feed roller 13 and the presser roller 1.
5 and is further fed in the direction of arrow A by these rows 213 and 15.
磁気カード２１は図示しない制御装置によりこれらの送

情報の記録を行ない、その後再び磁気カード２１は送り
ローラ１２と押えローラ１４との間に送り込１れてカー
ドリーダ筐体１０から送り出されることになる。The magnetic card 21 is reciprocated twice between the feed roller 13 and the presser roller 15 by a control device (not shown), during which time the magnetic head 16 faces the magnetic tape of the magnetic card 21 to read information from the magnetic card 21 and read the information. After that, the magnetic card 21 is again fed between the feed roller 12 and the presser roller 14 and sent out from the card reader housing 10.
ここで最とも重要な動作は磁気ヘッド１６による情報の
読み取り、並びに記録であり、これが正確に行なわれる
ためには磁気ヘッド１６が磁気カード２１に対して最適
位置に位置付けされている必要がある。The most important operation here is the reading and recording of information by the magnetic head 16, and in order to perform this accurately, the magnetic head 16 must be positioned at an optimal position with respect to the magnetic card 21.
すなわち磁気ヘッドは挿入される磁気カード面に対して
三次元的に正確に位置付けする必要がある。That is, the magnetic head must be accurately positioned three-dimensionally with respect to the surface of the magnetic card to be inserted.
これを説明するとヘッドにより正確に情報を読み取るた
めには第１にヘッドギャップが磁気記録部（磁気テープ
）に対して直角に対向し、第２にヘッドギャップが磁気
記録部に対し対向し、第３にヘッドギャップが磁気記録
部に対して片当りしないことが必要である。To explain this, in order for the head to read information accurately, firstly the head gap should face the magnetic recording section (magnetic tape) at right angles, secondly the head gap should face the magnetic recording section and the Third, it is necessary that the head gap does not make uneven contact with the magnetic recording section.
第２図ａ、ｂ 、ｃにより更に詳細に説明する。This will be explained in more detail with reference to FIGS. 2a, b, and c.
図において２１は磁気カード、ＭＧは磁気テーク、１６
は磁気ヘッド、１６ａはヘッドギャップである。In the figure, 21 is a magnetic card, MG is a magnetic tape, 16
is a magnetic head, and 16a is a head gap.
ａ図に示す如く、磁気ヘッド１６のヘッドギャップ１６
ａが磁気テープに対して斜めに配置されていると、情報
を読み取る場合、隣接する情報も同時に読み取るため正
確に情報を読み取れない。As shown in figure a, the head gap 16 of the magnetic head 16
If a is disposed diagonally with respect to the magnetic tape, when reading information, adjacent information will also be read at the same time, making it impossible to read the information accurately.
又情報を書込む場合斜めに情報を書き込むため、他の装
置に適用した場合読み取れなくなってしｌう。Furthermore, since the information is written diagonally, it becomes unreadable when applied to other devices.
ｂ図に示す如くヘッドギャップ１６ ａ ｉ’４Ｂ気テ
ープＭＧに対向していないと、情報を読取ったり、書き
込むことができない。If the head gap 16 is not opposed to the tape MG as shown in Figure b, information cannot be read or written.
又０図の如くヘッド１６が磁気テープＭＧに片当りして
いる場合も情報の読込み、書込みを正確に行なうことが
できない。Also, when the head 16 is in partial contact with the magnetic tape MG as shown in FIG. 0, information cannot be read or written accurately.
この様なヘッドのずれをなくすための従来の磁気ヘッド

如く磁気カードの移動平面と垂直をなす平面内において
調節支持板２２を磁気ヘッド取付板１７０側方に設けて
それらを正三角形の各頂点に配置した３本の調節ボルト
ｓｔ＋５ｚｔＳ３により連結し、その３本の調節ボルト
Ｓ 。In order to eliminate such head misalignment, the conventional position adjustment mechanism for mounting the magnetic head is to move the adjustment support plate 22 in a plane perpendicular to the plane of movement of the magnetic card, as shown in FIGS. 3a and 3b, for example. The three adjustment bolts S are provided on the side of the magnetic head mounting plate 170 and connected by three adjustment bolts st+5ztS3 arranged at each vertex of an equilateral triangle.
Ｓ２．Ｓ３を調節することにより磁気カード進行方向に
対する磁気ヘッド１６の方向位置調節（第１図ａ、ｂに
示す様なずれの調整）とその進行方向に直角な平面内に
おける磁気ヘッドの傾斜位置調節（第１図Ｃに示す様な
片当りの調整とを行なうようにした磁気ヘッドの取付は
位置調節機構が公知である。S2. By adjusting S3, it is possible to adjust the directional position of the magnetic head 16 with respect to the direction of movement of the magnetic card (adjustment of deviations as shown in FIGS. A position adjustment mechanism is known for mounting a magnetic head to adjust the uneven contact as shown in FIG. 1C.
しかしながらこのような磁気ヘッドの取付は位置調節機
構では３本の調節ボルトのうち一本の調節ボルトを調節
回転すると磁気カード進行方向に対する磁気ヘッドの方

ヘッドの位置付けが極めて困難であるという欠点を有し
ている。However, when installing the magnetic head in this way, when one of the three adjustment bolts is adjusted and rotated, the directional position of the magnetic head with respect to the magnetic card traveling direction and the magnetic field in a plane perpendicular to the card traveling direction can be adjusted. This method has the disadvantage that the tilted position of the head may shift at the same time, making it extremely difficult to position the magnetic head.
例えば調節ボルトＳ２により第２図Ｃの様な片当りをな

ド１６が磁気カードに片当りする様に傾斜が生じていた
。For example, if the adjustment bolt S2 is used to eliminate the uneven contact as shown in FIG. 2C, and then the adjustment bolt S3 is turned to eliminate the deviation as shown in FIG.
Since the head 16 rotates around the straight line sTl connecting the points s2, an inclination occurs so that the head 16 makes partial contact with the magnetic card again.
図の構成において、第２図に示す様なずれをなくすため
には、例えば調節ボルトＳｆ：磁気ヘッド側に押し込み
、調節ボルトＳ をＳ の押し込み分だけ磁気ヘッドと
反対側に戻すとよい。In the configuration shown in the figure, in order to eliminate the shift shown in FIG. 2, it is preferable to push the adjustment bolt Sf toward the magnetic head side, and return the adjustment bolt S to the side opposite to the magnetic head by the amount of push S.sub.2.
本考案の目的はカード進行方向に対する磁気ヘッドの方

上述の欠点を除去した磁気ヘッドの取り付は位置調節機
構を提供することにある。The object of the present invention is to enable independent adjustment of the directional position of the magnetic head with respect to the card advancing direction and the inclination position of the magnetic head within a plane perpendicular to the card advancing direction, thereby eliminating the above-mentioned drawbacks. The purpose of mounting the head is to provide a position adjustment mechanism.
