BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection having a spring means for inserting and removing an IC card containing an IC into and from an IC card insertion opening of an external device and ejecting the IC card inserted into the IC card insertion opening. The present invention relates to a structure for connecting an IC card to an external device, which prevents the IC card from accidentally popping out of the IC card insertion opening when the inserted IC card is ejected.

2. Description of the Related Art Conventionally, as a connection structure for inserting and removing an IC card having an IC built into an IC card insertion port of an external device, as shown in a perspective view of FIG. 6 and a sectional view of FIG. When the IC card 2 is ejected from the external device 1, the inserted IC card 2 is easily ejected. Therefore, the push button is pushed against the contact pressure between the connection terminal of the inserted IC card 2 and the contact of the connector. Press A,
The IC card 2 is disengaged from the connector, and the urging force of the spring 4 locked to the sliding plate 3 on which the IC card 2 is placed causes the IC card 2 to
The card 2 is ejected to the outside of the external device 1. However, there is a problem in that the IC card 2 pops out from the IC card insertion opening of the external device 1 due to the urging force of the spring and falls on the floor surface, damaging the IC card 2.

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned problems, and the gist thereof is an IC having an IC built therein.
In the connection structure of the IC card to the external device, the card being inserted into and removed from the IC card insertion port of the external device, and the IC card having spring means for ejecting the IC card inserted into the IC card insertion port is connected to the external device. To the external device of the IC card, which is provided with a braking unit that suppresses the ejection of the IC card when it is ejected, and prevents the IC card from accidentally jumping out from the IC card insertion slot when the inserted IC card is ejected Is a connection structure of.

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a sectional view showing a main part of an embodiment of a connection structure of an IC card of the present invention to an external device, FIG. 2 is a sectional view showing a main part of another braking portion of the present invention, and FIGS. FIG. 5 is a cross-sectional view showing the main part of another embodiment of the present invention, and FIG. 5 is a plan view of the sliding plate shown in FIG.

As shown in the sectional view of FIG. 1, when the IC card 2 is ejected from the external device 1, the inserted IC card 2 is easily ejected. When the push button A (not shown) is pressed against the contact pressure with the IC card 2, the IC card 2 is disengaged from the connector, and the spring 4 (illustrated in the figure) locked to the sliding plate 3 on which the IC card 2 is mounted is shown. By the urging force of
Although the card 2 is discharged to the outside of the external device 1 as in the conventional case, the present invention is characterized in that a braking portion 5 for suppressing the discharge of the IC card 2 is provided.

As the braking portion 5, a flat plate made of a rubber material such as synthetic rubber or natural rubber may be formed into a belt shape and fixed to the insertion port of the IC card 2 into the external device 1 by adhesion or the like. The braking unit 5 is not limited to the belt-shaped member shown in FIG. 1, but as shown in FIG.
A braking portion formed so as to fit in the fixed frame 52 may be provided in the IC card insertion port, or as shown in FIG. 2B, a prismatic rubber material 51 is fitted in the fixed frame 52. A braking portion formed so as to fit may be provided in the IC card insertion slot.
Further, as the braking unit 5, the IC card 2 for the external device 1 is used.
However, the braking portion 5 may be formed by forming a coating film having an adhesive property on the sliding plate 3 on which the IC card 2 is placed, as shown in the sectional view of FIG. .

Further, as shown in FIGS. 4 to 5, a guide groove 53 parallel to the discharging direction P of the IC card 2 and a guide groove 54 oblique to the discharging direction P are formed on the sliding plate 3, and one of them is formed. By engaging with these guide grooves 53 and 54, protrusions that are slidable in a direction orthogonal to the ejection direction P of the IC card 2, guide grooves 54 formed in an oblique direction when the IC card 2 is ejected. A braking portion including the guide groove 54 and the protrusion 55 may be provided so as to suppress the ejection of the IC card due to the resistance force when the protrusion 55 slides along.
The length of the guide groove 53 parallel to the extraction direction P of the IC card 2 may be set so that the connection terminal of the IC card 2 is disengaged from the contact of the connector of the external device.

[0008]

The present invention has a structure for connecting an IC card having a spring means for ejecting the IC card inserted into the IC card insertion slot to an external device, when the inserted IC card is ejected. Since the braking portion that suppresses the discharge of the IC card is provided, there is an advantage that the IC card does not inadvertently pop out from the IC card insertion slot.
