たものが考えられた。(B) Conventional technology An IC card reader performs data processing on an inserted IC card by making a contact resiliently contact a contact of the external IC with the external IC contact.
As shown in FIG. 4, the contact 11 is a spring, and
12 divided into two, or a torsion coil spring with high contact reliability and compactness as shown in FIG.
13 is formed by bending a spring wire 14 having a circular cross section to form a contact contact portion 15, and a spring wire of a torsion coil spring 13 as shown in FIG.
14 was crushed to form a contact contact portion 16 having a flat cross section in FIG.
（ハ）発明が解決しようとする課題 しかるに、第４図の板バネ製接触子11では、接点接触
部12の側面にシャープなエッジ部が生じるので、カード
に反りがあると、上記エッジ部が高い接触圧でカードの
IC接点に当たり、IC接点を傷付ける欠点があった。(C) Problems to be Solved by the Invention However, in the leaf spring contact 11 shown in FIG. 4, a sharp edge is formed on the side surface of the contact contact portion 12, so that if the card is warped, the edge will be Card with high contact pressure
There was a drawback that the IC contact was damaged.
また、第５図のねじりコイルバネ製接触子17の場合で
も、バネワイヤ14がＲの小さな円形断面をしているの
で、ICカードに点接触対応し、該カードに反りがあれば
その点接触部の接触圧が増大した。Also, in the case of the torsion coil spring contact 17 shown in FIG. 5, since the spring wire 14 has a small circular cross section of R, it corresponds to a point contact with the IC card. The contact pressure has increased.
第６図の構造を改良した第７図の接触子18は、接点接
触部16を扁平化することで、接触面圧を下げるようにし
たものであるが、第７図の矢印で示す両側ではやはりＲ

題が生じた。The contact 18 shown in FIG. 7 which is an improvement of the structure shown in FIG. 6 is designed to reduce the contact surface pressure by flattening the contact portion 16. After all R
Is so small that the card is warped and the same problem occurs if this small portion of R contacts the IC card.
この発明は上記問題点を解消する接触子の提供を目的
とする。An object of the present invention is to provide a contact that solves the above problems.

接触子であることを特徴とする。(D) Means for Solving the Problems The present invention is an IC card reader for executing data processing such as reading or writing data on an IC card electrically contacted by a contact, and comprising: , Formed of a torsion coil spring that elastically contacts the external IC contact of the IC card, and the spring wire of the part that contacts the external IC contact of the IC card has a contact surface with a large radius of curvature and a wide area on one surface The IC card reader is characterized in that it is a contact of an IC card reader which is caulked so as to form a reinforcing overlay on its back surface.
（ホ）作用 この発明によれば、接触子はその大きな曲率半径の接
触面、つまりＲの大きな、広い面で常にICカードの外部
IC接点に接すると共に、この接触面を形成したバネワイ
ヤのカシメ部分が、カシメ加工による扁平化にかかわら
ず接触面裏面の肉盛り部によって補強される。(E) Action According to the present invention, the contact is always provided outside the IC card on the contact surface having a large radius of curvature, that is, a large surface having a large radius.
While being in contact with the IC contact, the caulked portion of the spring wire forming the contact surface is reinforced by the build-up portion on the back surface of the contact surface irrespective of flattening by caulking.
（へ）発明の効果 従って、この発明によれば次のような効果を奏する。(F) Effects of the Invention Therefore, according to the present invention, the following effects are obtained.
ICカードに反りがあっても、接触子はそのＲの大き
な、広い接触面での接触を保ち続けることによって、接
触面圧の増大を避けることができ、それゆえIC接点の傷
付き、破壊がなくせる。Even if the IC card is warped, the contact can maintain the contact on the large contact surface with a large R, thereby avoiding an increase in the contact surface pressure, thereby preventing the IC contact from being damaged or broken. Can be lost.
カシメ部にはたらく応力に対し、肉盛り部が接点接触
部の強度を高めて強力に対抗するので、カシメ加工にか
かわらず接触子の折損などが生じない。Since the build-up portion increases the strength of the contact portion and strongly opposes the stress acting on the caulking portion, the contact does not break regardless of the caulking process.
したがって、ICカードリーダれは良好な接触子の条件
でデータ処理が確実に実行できる。Therefore, the IC card reader can reliably execute data processing under good contact conditions.

けられ、他端に、コイル部分４から外方へ伸ばしたバネ
ワイヤ２に接点接触部５が形成される。The contact 1 is a torsion coil spring manufactured by using a spring wire 2 having a circular cross section. When this coil spring is incorporated into an IC card reader at one end of the coil spring,
An engaging portion 3 for fastening to the reader-side fixed frame is provided, and a contact contact portion 5 is formed on the other end of the spring wire 2 extending outward from the coil portion 4.
この接点接触部５はバネワイヤ２を屈曲させた部分に
構成されており、この部分ではバネワイヤ２にカシメ加
工を加えて、接点接触部５の断面形状が第２図のように
成形される。The contact contact portion 5 is formed in a portion where the spring wire 2 is bent. In this portion, the spring wire 2 is caulked to form a cross-sectional shape of the contact contact portion 5 as shown in FIG.
すなわち、接点接触部５では、カードＡに接触する側

点接触面６の裏面（上面）に山形に盛り上がった肉盛り
部７が形成される。That is, in the contact contact portion 5, the surface on the side contacting the card A, that is, the contact contact surface 6 is formed into a wide surface having a large radius of curvature R1 and curved in the width direction. On the back surface (upper surface), a built-up portion 7 protruding in a mountain shape is formed.

力集中を避けている。By caulking the spring wire 2 with a thin circular cross section,
If the spring wire is simply flattened, the thickness difference between the caulked portion and the spring wire portions before and after the caulked portion becomes remarkable as shown in the example of FIG. 3, and stress concentrates on the boundary between the spring wire and the caulked portion. The contact contact portion 5 is easily broken. The built-up portion 7 prevents this, and secures the thickness of the central portion connected to the spring wire 2 of the caulked portion, thereby increasing the strength of the contact contact portion 5 and reducing the concentration of stress on the contact contact portion. Avoiding.
