Detailed Description of the Invention [Industrial applications]

The present invention relates to a device for reading and writing an IC card in which an IC chip is embedded.

[Prior art]

FIGS. 3 and 4 are a plan view and a side sectional view of an IC card reading / writing device for reading and writing necessary data using the IC card 14, and FIG.
The operation is shown in FIG. The configuration will be described with reference to these drawings. Reference numeral 1 denotes a flat box-shaped case, and a slit-shaped card insertion opening 2 for inserting an IC card 14 is provided in a lower portion of a front side wall 1a of the case 1, and the case 1 is provided inside the case 1. Is formed with a card transport path 3 which is a path through which the IC card 14 is transferred in a state of sliding contact with both sides of the lower surface of the IC card 14 inserted through the card insertion slot 2.
In the vicinity of the card insertion slot 2 in the case 1, a transfer means 6 for the IC card 14 including a motor 4 and a roller 5 mounted on a shaft S rotated by the motor 4 via a gear W is arranged. ing. Further, one end is fixed to a predetermined portion of the rear side wall 1b of the case 1, and as guide members, two guide grooves 7 extending at a predetermined angle with respect to the card transport path 3 are provided on both sides of the case 1. A contact head 8 is provided on a predetermined portion of a slider 21 that is provided on the wall and that engages with the guide groove 7 and slides along the groove 7. At the rear end of the contact head 8, the card transport path 3
A protruding portion 8a is formed so as to abut with, and makes a conductive contact with the reading and writing terminals of the IC card 14,
A contact pin 9 as a conductive contact means is provided so as to be movable up and down, and the contact pin 9 is a spring.
It is pushed down by the urging force of 10 (see Fig. 5).
Further, the contact head 8 is positioned in a pressed state by a biasing force of the spring 11 at a position (referred to as a home position) where the contact head 8 stops at a stopper 7a (see FIG. 5) provided at a predetermined portion. 12 and 13 (see Fig. 5) are ICs
Card detectors for detecting the insertion and ejection states of the card 14, which are arranged on the front side and the rear side of the case 1, respectively. Next, the operation of the conventional device configured as described above will be described with reference to FIGS. 5 (A) to 5 (C). When the IC card 14 is inserted from the card insertion slot 2 with the terminal 15 facing upward as shown in FIG. 5 (A), first, the insertion of the IC card 14 is detected by the card detector 12. The motor 4 of the transfer means 6 starts forward rotation based on the detection signal from the IC card 14 and the rotation of the roller 5 draws the IC card 14 into the case 1 along the card transport path 3. As the card is pulled in, the tip of the IC card 14 is projected from the contact head 8 as shown in FIG. 5 (B).
When it comes into contact with 8a, thereafter, the contact head 8 also moves integrally with the transfer of the IC card 14 toward the rear side wall 1b. At this time, since the contact head 8 moves along the inclined guide groove 7, the contact head 8 moves down. Now, as shown in FIG. 5 (C), when the contact head 8 contacts the inner wall of the rear side of the case 1 and the tip of the IC card 14 is positioned on the card detector 13, the card detector 13 The completion of insertion of the IC card 14 is detected by this, and the motor 4 is stopped based on the detection signal from the card detector 13. At this time, the contact pin 9 of the contact head 8 is brought into conductive contact with the terminal 15 of the IC card 14 by an appropriate contact pressure of the spring 10. When the reading and writing of data from the IC card 14 is completed in this state and a card ejection signal is output from a host device (not shown), the motor 4 of the transfer means 6 reversely rotates and the IC card
The roller 14 is transported backward by the roller 5 toward the card insertion slot 2. At this time, the contact head 8 moves toward the original home position so as to follow the movement of the IC card 14 by the urging force of the spring 11, and the contact pin 9 and
Release the conductive contact with the terminal 15 of the IC card 14. Finally, when the IC card 14 passes through the roller 5 and is in the state before the card is pulled in, when the IC card 14 is pulled out, the card detector 12
Thus, card ejection is detected, and as a result, the motor 4 stops.

[Problems to be Solved by the Invention]

As described above, two rollers 5 are provided on the shaft S at positions where they abut on both side edge portions of the IC card 14, and the IC card 14 is fed by the rotation of these rollers 5 and the IC
The surface of the roller 5 is coated with an elastomeric material so as not to scratch the surface of the card 14. Therefore, the cost of the roller 5 is increased, and the number of assembling steps is increased, so that the apparatus becomes expensive. The present invention has been made to eliminate the above-mentioned problems, and is an IC that reduces the number of rollers and reduces the cost of the device.
An object is to provide a card reading / writing device.

[Means for Solving the Problems]

The present invention, card detection means for detecting the IC card inserted into the card insertion slot, based on the card detection signal from the card detection means,
The IC card is pulled into the inside of the device by the rotation of the roller, and the transfer means for ejecting the IC card that has been pulled into the card insertion slot;
A contact head that descends / rises along an inclined guide member, and a conductive contact means that is provided on the contact head and that contacts a read / write terminal of the IC card when the IC card is pulled into a predetermined position. In the IC card reading / writing device including the above, the roller is a single roller that presses one side edge side of the IC card from above, and the IC card on the other side edge side is pressed by this pressing. It is characterized in that a guide plate is provided to prevent the jumping up of the.

[Action]

According to the above configuration, when the IC card is inserted, the insertion of the IC card is detected, the roller is driven by the driving of the motor, and the IC card is pulled inside the device. At this time, IC
Since the card is transported by one roller provided on one side edge side, if the IC card is warped, the other side edge side may jump up, but the guide plate prevents this jumping up. Therefore, the IC card will be delivered normally without any problems.

【Example】

Preferred embodiments of an IC card reading / writing device according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing an embodiment of an IC card reading / writing apparatus of the present invention, and FIG. 2 is a sectional view seen from the card insertion port side. In these figures, parts having the same functions as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. In the figure, the roller 5 made of an elastic body for feeding the IC card 14 is attached to the gear W at the attachment position side,
The other roller 5 is omitted. Instead, a guide plate 22 separated from the upper surface of the IC card 14 by a predetermined gap G is provided substantially at the center of the side edge on the side where the roller 5 is abolished.
The guide plate 22 also serves as a stopper when the slider 21 returns to the home position. Next, the operation of the apparatus having the above configuration will be described. When the IC card 14 is inserted through the card insertion slot 2, the insertion of the IC card 14 is detected, the motor 4 is driven, the roller 4 is rotated, and the IC card 14 is pulled into the apparatus, as in the conventional example. At this time, since the IC card 14 is transferred by the roller 5 at one side edge, if the IC card 14 is warped, the other side edge side may jump up, but the guide plate 22 causes this jumping up. IC card will be deterred
14 is delivered normally without any problems.

【The invention's effect】

As described above, according to the present invention, by providing the guide plate in the transfer path of the IC card, it is possible to reduce the number of rollers made of an elastic body for feeding the IC card to one. By reducing the number of manufacturing steps, the device can be constructed at low cost.
