Next, the operation of the IC card of this embodiment having such a configuration will be described. First, when the IC card is not used, the pressing portion 61 of the stopper 60 is not pressed (the state shown in FIG. 3A), and the rotating plate 30 is urged by the coil spring 50. The cable 20 is wound around the winding shaft 31 of the rotating plate 30 and is housed in the card body 10.

At this time, since the line side connector 21 at the end of the cable 20 serves as a stopper and is locked in the concave portion of the cable outlet 13 of the card body 10, the entire cable 20 is pulled into the card body 10. There is no end.

Next, when using an IC card,
First, the card body 10 is inserted into the device (not shown) from the device side connector 11 side. When the card body 10 is inserted into the device, the pressing portion 61 of the stopper 60 is automatically pressed by the inner wall of the insertion portion of the device, the stopper 60 swells inside the card body 10, and the engaging portion 62 It moves forward to a position where it engages with the engaging claw 32, and both engage (the state of FIG. 3B).

In this state, the rotary side plate 30 is pulled against the urging force of the coil spring 50 by pulling the line-side connector 21 that is locked in the cable outlet 13 to move the rotary plate 30 in the direction of the arrow A in the drawing.
And rotate in the opposite direction. At this time, the opposite sides of the engaging claw 32 of the rotating plate 30 and the engaging surface of the engaging portion 62 are each formed with a curved surface, and the through hole 30 a of the rotating plate 30 is freely inserted into the shaft portion 42 of the support shaft 40. Since it is in the state and can move in the radial direction, the engaging claw 32 can get over the engaging portion 62 and rotate the rotating plate 30. Thus, the cable 20 can be pulled out by a desired length.

When the cable 20 is released when the cable 20 is pulled out by a required length, the rotating plate 30 rotates in the direction of arrow A in the drawing by the urging force of the coil spring 50.
When any one of the engaging claws 32 provided at three places of the rotating plate 30 comes into contact with the engaging portion 62 of the stopper 60, the two engage with each other, so that the rotation of the rotating plate 30 stops.

As a result, the cable 20 remains pulled out, and the IC card can be used by freely connecting to the external line or the like. When the length of the cable 20 is insufficient, the cable 20 can be pulled out by further pulling the cable 20.

After the IC card is used, the card body 10 is pulled out from the apparatus side, so that the pressing portion 61 is no longer pressed, so that the stopper 60 returns to its original position and the rotary plate 30 is removed.
The engagement between the engaging claw 32 and the engaging portion 62 is released (the state shown in FIG. 3A), so that the rotating plate 30 is rotated in the direction of the arrow A in the drawing by the urging force of the coil spring 50. As a result, the cable 20 is automatically rolled up and stored in the card body 10, so that the IC card can be carried.

As described above, according to the IC card of the present embodiment, the cable 20 for connecting the IC card to the external line is housed inside the card body 10 when the IC card is not used, so that the conventional Cable to IC
There is no need to remove it from the card and manage it separately, making it highly portable.

Further, since the cable 20 is integrally connected to the card body 10 side, it is not necessary to connect the cable 20 to the IC card side, only the cable 20 needs to be pulled out at the time of use, and the card body after use. Since the cable 20 is automatically stored only by pulling out 10 from the device side, it is excellent in simplicity and operability.
