DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the C card input / output device 50, four parallel contact terminals 5
3a is linearly arranged with four parallel contact terminals 53b in the insertion direction X so that the four end portions 53ab are arranged in close contact with the four end portions 53bb, respectively. Therefore, the depth dimension of the insertion chamber 52 needs at least the sum of the length L2 of the contact C5 and one end of the IC card and the length L3 of the terminal portion 53ba and the contact 53bc. As a result, there is a problem that the size of the conventional IC card input / output device 50 cannot be significantly reduced. Further, in the conventional IC card input / output device 50, the respective parts L4 and L4 ′ do not function as springs.
Therefore, in order to obtain a predetermined contact pressure, it was required to make the length L3 and the length L3 ′ between the end portion 53aa and the contact point 53ac as long as possible.

Further, the conventional IC card input / output device 50
Then, there is a possibility that the contact terminal 53a may be permanently deformed. This permanent deformation will be described with reference to FIGS. 11 (a) and 11 (b). 11A is an explanatory view showing a state before the contact terminals shown in FIG. 10B are mounted on the main surface of the IC card, and FIG. 11B is an IC card in which the contact terminals are shown in FIG. It is explanatory drawing which shows the state after riding on the main surface. 11A and 11B.
As shown in, when the terminal end portion 53ab rides on the main surface of the IC card 80, the pushing force from the front end of the IC card 80 directly acts on the terminal portion 53aa from the terminal end portion 53ab. As a result, as the IC card 80 is inserted into the insertion chamber 52, the internal stress increases at the terminal end portion 53ab. As a result, the contact terminal 53a may be permanently deformed.

On the other hand, in order to reduce the area of the insertion chamber, it is known to improve the arrangement of the contact terminals.
It is known from, for example, Japanese Patent No. 466. The improved arrangement of the contact terminals will be described with reference to FIG. FIG. 12 is an explanatory diagram showing an arrangement of contact terminals in a conventional IC card input / output device described in Japanese Patent Laid-Open No. 5-6466.

Similarly, the three long contact terminals 61b are arranged at a predetermined angle with respect to the direction perpendicular to the row of contact points and are in contact with the three contact points C1--C3, respectively. Furthermore, the three short contact terminals 61a and the three long contact terminals 61b are arranged alternately in the direction perpendicular to the row of contacts. Thus, in this conventional IC card input / output device, the area of the insertion chamber has been reduced by improving the arrangement of the contact terminals.

However, in this conventional IC card input / output device, in order to insulate the contact terminals 61a and 61b from each other, the width of the contact terminals 61a and 61b may be made larger than half the distance P between the two contacts. could not. Therefore, due to such a small width W, the contact terminal 61
There is a problem that the strengths of a and 61b are not sufficient.
Further, this conventional IC card input / output device is suitable for inserting the IC card 80 from the directions shown by arrows Y and Z in FIG. 13 which is a side view of the contact terminal 61a. That is, this conventional IC card input / output device is unsuitable for inserting the IC card 80 from the direction opposite to the arrow Z.
