The rollers 2a and 2b of the card guide roller 2 and the suppressing roller 4 and probe 5, which will be described later, are provided with a spacing corresponding to the thickness of the IC card 7 at a substantially intermediate position t, and are rotatable on shafts 3c and 3d, respectively. It is pivoted.

The cylindrical pressure roller 4 is also formed of a rubber member, and each roller 2a, 2b, 3a, of the card guide roller 2.3
It has a larger diameter than 3b. The suppression roller 4 is rotatably supported on a shaft 4a directly above a probe 5, which will be described later. The distance between the pressing roller 4 and the probe 5 is slightly narrower than the thickness of the IC card 7, and the probe 5 is configured to reliably rotate by a certain angle in response to the insertion of the IC card 7.

The probe 5 includes a glove body 5a having a plurality of connection terminals 5b, . . . , a card support 5C15d formed at both ends of the probe body 5a, and a torsion spring 5e.

It is made to protrude slightly from the peripheral surface of the probe body 5a. On the other hand, the proximal end protruding from the opposite side of the peripheral surface of the probe body 5a is used to send and receive data to and from the IC card 7.
Each lead wire 51 is connected to a data processing device (not shown).

The cart supports 5c and 5d both form a disk body, and have the same radius as the radius of the circumferential surface of the probe body 5a.

A protrusion 5f is formed on the outer surface of the card support 5c to engage one end of a torsion spring 5e fitted into the shaft 5h. A convex portion 5g is formed which abuts on the protruding bodies 6a and 6b and restricts the movable range of the probe 5. (FIGS. 1 to 3) One end of the torsion spring 5e is locked to the convex portion 5f of the card support 5C, and the other end is connected to the probe support 6 described later.
It is locked to the protruding body 6a.

As shown in FIG.
It has a letter shape and is provided close to the probe 5. A concave stopper portion 6c is provided above the vertical portion of the probe support 6. By inserting the IC card 7, the probe 5 is rotated, and the external terminals 7a, . . . formed on the IC card 7 and the connecting terminals 5b, .

In addition, in order to prevent excessive rotation of the probe 5, a protrusion 6a is provided in the horizontal direction at the center of the edge of the vertical part of the probe support 6 so as to be able to engage with the protrusion 5g of the card support 5C.
A protrusion 6b is provided vertically upward at the tip of the edge of the horizontal portion.

As described above, when the probe 5 is in a non-contact state with the IC car 17, the torsion spring 5e

A force is applied to rotate counterclockwise. However, the probe 5 stops with the bias stored at the position shown in FIG. 1 where the protrusion 5g of the card support 5C abuts the protrusion 6a of the probe support 6.

Further, when the IC card 7 is inserted between the probe 5 and the suppression roller 4, the probe 5 is rotated by a certain angle as the IC card 7 moves a certain distance,
The external terminals 7a, . . . of the IC card 7 and the connection terminals 5b, . At this time, I
The movements of the C card 7 and the probe 5 are both stopped by the probe support 6. In this state, the IC card 7 is pushed against the pressing roller 4 against the biasing force of the torsion spring 5e.
It is configured to be fixed by the pressing force between the probe 5 and the probe 5.

Next, the effect will be explained.

By inserting the IC cart 7 into the card insertion slot 1a, the IC card 7 is guided to the card guide rollers 2 and 3 via the card guide section 1b.

Furthermore, IC card 7 is fixed! 4 When pushed in, it moves to the right while being held between the suppression roller 4 and the probe 5. In response to this movement of the IC card 7, the probe 5, which was in a fixed position, is rotated by a certain angle together with the suppression roller 4. Connection terminals 5b, . . . provided on the peripheral surface of the probe 5, and external terminals 7a of the IC card 7
, ... are in a connected state, and data is exchanged with a processing device (not shown). At this time, the tip of the IC card 7 hits the stopper part 6c provided on the vertical part of the probe support 6. The IC card 7 is prevented from moving to the right. On the other hand, the probe 5 has a convex portion 5g.

It rotates from the position where it was attached to the protrusion 6a on the vertical part of the probe support 6 in the direction of the protrusion 6b on the horizontal part of the probe support 6, and the rotation stops at the position where it comes into contact with the protrusion 6b on the horizontal part of the probe support 6. will be stopped.

Therefore, the external terminal 7a of the IC card 7...
It is possible to ensure the connection between . . . and the connection terminal 5b of the probe 5, and prevent connection failures.

As shown in FIG. 2, when the IC card 7 and the probe 5 are stopped by the probe support 6,
The C card 7 is clamped and fixed by the clamping force of the pressure roller 4 and the probe 5 against the biasing force of the torsion spring 5e. When the data processing of the 0th order is completed and the IC card 7 is extended, , the suppression roller 4 and the probe 5 are rotated in the opposite direction to the previous direction, and the IC card 7 can be taken out via the card guide roller 3.2 and the card guide section 1b.

As the IC card 7 is pulled out, the probe 5 is urged to rotate to the left in the figure by the torsion spring 5e, but the protrusion 5g of the card support 5b engages the protrusion 6a of the stopper 6, Since it can always be returned to its normal position, the same operation can be repeated.

[Second Example J Next, a second embodiment will be explained.

As shown in FIG. 5, in the IC card connecting device of this embodiment, the IC card 7 is automatically pulled in when it reaches a certain point. Motor 14, photo sensor 15.16
It consists of

A slanted card insertion slot 11 is provided on the front side of the card insertion part 11.

Directly below this drive roller 12, a probe 13 having connection terminals 13a, . The probe 13 is configured to be able to move while holding the inserted IC car 17 together with the drive roller 2.

The drive roller 12 is driven by a motor 14! l! It is configured to rotate or stop via a transmission means 12b (for example, a belt, etc.) by moving or stopping.

The photosensor 15 is a light emitting element (for example, a light emitting diode)
15a and a light receiving element (for example, a phototransistor) 15b
The drive roller 12 and the prong 13 are provided oppositely between their axes.

When this photo sensor 15 detects the arrival of the IC card 7, the motor 14 is driven to drive the drive roller 12,
Input IC card 7. The probe 13 is rotated in conjunction with the movement of the IC card 7, and the external terminals 7a of the IC card 7, . . . are connected to the connection terminals 13a of the probe 13,
Connect with... In this state, a photosensor 16 consisting of one light-emitting element 16a and one light-receiving element 16b is provided at the tip of the IC card 7 (right end in the figure) so as to face each other vertically. When this photo sensor 16 detects the arrival of an IC card, the drive of the motor 14 is stopped and the IC card is detected.
Hold the C card 7 in that position.

According to this IC card connection structure, the card guide slot 11a
When the IC card 7 is inserted, it is guided through the card guide section 11b until the tip of the IC card 7 contacts the drive roller 12 and the probe 13 (Fig. 5). At this time, the photo sensor 15 is inserted into the card. When the arrival is detected, the motor 14 is driven. By driving this motor 14, rotation is transmitted to the drive roller 12 via the transmission means 12b.

Since the IC card 7 is in contact with the drive roller 12 and the probe 13, if the drive roller 12 rotates counterclockwise in FIG.

3a, . . . are connected. At this time, the photo sensor 16 detects the IC card 7, the motor 14 stops driving, and the IC card 7 stops (Figure 286).
Thereafter, data is exchanged with a processing device (not shown). When the data processing is completed, the signal is transmitted to the processing device, and then a command is issued to reversely rotate the motor 14.
The IC card 7 is carried out to the left.

When the IC card 7 is taken out, the probe 13
Following this, it is rotated to the initial position. Therefore, the same operation can be repeated thereafter.

Incidentally, according to the above embodiment, the probe is in direct contact with the IC card, but the present invention is not limited to this, and the probe can be rotated by storing the IC card in a holder and moving the holder. Alternatively, the external terminal of the IC card and the connection terminal of the probe may be connected.

Effects of the Invention 1 As explained in detail above, this invention uses a rotating probe as the probe, so that the probe itself only needs to be rotated at a fixed position in response to the insertion of an IC card. The whole can be made compact. Furthermore, the structure can be simplified and costs can be reduced.
