Abstract

PURPOSE:To suppress the cost of a device by decreasing the number of rollers by providing one piece of roller on a side edge side of an IC card, and also, providing a guide plate for inhibiting jump-up of the IC card on the other side edge side. CONSTITUTION:When an IC card 14 is inserted, the insertion of the IC card 14 is detected, a roller 5 is rotated by driving of a motor 4, and the IC card 14 is drawn into the inside of a device. In this case, the IC card 14 is transferred by one piece of roller 5 provided on one side edge side, therefore, in the case there are a curve, etc., in the IC card 14, sometimes the other side edge side jumps up, but since this jump-out is inhibited by a guide plate 22, the IC card 14 is fed normally without a hindrance. In such a way, the number of rollers consisting of an elastic body for feeding the IC card can be decreased to one piece, and the number of parts and the manufacturing process are decreased, therefore, the device can be constituted at a low cost.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a device that reads and writes to an IC card in which an IC chip is embedded.

[Conventional technology]

3 and 4 show a plan view and a side sectional view of an IC card reading/writing device that reads and writes necessary data using an IC card l4, and FIG.
The operation is shown in A) to FIG. 5(C). The structure will be explained using these figures. 1 is a flat box-shaped case, and a slit-shaped card insertion slot 2, which is an insertion slot for an IC card 14, is provided at the lower part of the front side wall 1a of the case l.
A card conveyance path 3 is formed inside the case 1 and serves as a path through which the IC card 14 is transported while being in sliding contact with both sides of the lower surface of the IC card 14 inserted through the card insertion slot 2. In addition, near the card insertion slot 2 inside the case 1,
An IC consisting of a motor 4 and a roller 5 attached to a shaft S that is rotationally driven by the motor 4 via a gear W.
A transport means 6 for the card I4 is provided. Furthermore, one end is fixed to a predetermined part of the rear side wall tb of the case 1, and
As guide members, two guide grooves 7 extending at a predetermined angle with respect to the card conveyance path 3 are provided on both side walls of the case l. A contact head 8 is provided at a predetermined portion of the slider 21 along which it slides. A card conveyance path 3 is provided at the rear end of this contact head 8.
A protrusion 8 & is formed so as to come into contact with the father, I
A contact pin 9 as a conductive contact means that makes conductive contact with the reading and writing terminals of the C card 14 is provided so as to be movable up and down. being pushed down by forces. Furthermore, the contact head 8 is held in place (referred to as a home position) where it stops at a stopper 7a (see FIG. 5) provided at a predetermined portion by the biasing force of the spring 1l. 12 and 13 (see Figure 5)
are card detectors for detecting the insertion and ejection states of the IC card 14, which are arranged at predetermined positions on the front side and the rear side of the case 1, respectively. Next, the operation of the conventional device configured as described above is shown in Figure 5 (
This will be explained using A) to FIG. 5(C). As shown in FIG. 5(A), connect the IC card l4 to the terminal l5.
When you insert the card from the card slot 2 with the card facing upward, first,
The insertion of the IC card 14 is detected by the card detector I2, and based on the detection signal from the card detector I2, the motor 4 of the transfer means 6 starts normal rotation, and the rotation of the roller 5 causes the IC card 14 to be transferred to the card transfer path. 3 into the case l. Along with this card withdrawal, Figure 5 (
As shown in B), when the tip of the IC card l4 comes into contact with the protrusion 8a of the contact head 8, the IC
As the C card 14 is transferred, the contact head 8 also moves together 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 descends. Now, as shown in FIG. 5(C), when the contact head 8 comes into contact with the rear inner wall of the case l and the tip of the IC card l4 is positioned above the card detector l3, the card detector l3 Completion of insertion of the IC card 14 is detected, and the motor 4 is stopped based on a detection signal from the card detector l3. Also, at this time, the contact pin 9 of the contact head 8 comes into conductive contact with the terminal 15 of the IC card 14 by the appropriate contact pressure of the spring 10. In this state, when data reading and writing from the IC card 14 is completed and a card ejection signal is output from the host device (not shown), the motor 4 of the transfer means 6 is reversed, and the TC
The card l4 is transported back toward the card insertion slot 2 by the roller 5. At this time, the contact head 8 moves toward the original home position by following the movement of the IC card 14 due to the biasing force of the spring 11, and breaks the conductive contact between the contact bin 9 and the terminal I5 of the IC card l4. . Finally, the IC card l4 passes through the roller 5,
IC card 14 when the card is in a state of inebriation.
When the card is pulled out, card ejection is detected by the card detector 12, and as a result, the motor 4 is stopped.

[Problem to be solved by the invention]

As mentioned above, two rollers 5 are provided on the shaft S at positions that contact both side edge portions of the IC card 14, and the rotation of these rollers 5 feeds the IC card 14 and The surface of the roller 5 is coated with an elastomer material to avoid scratching the surface. Therefore, the cost of the cap 5 was increased, and the number of assembly steps was also increased, making the device expensive. The present invention was made in order to eliminate the above-mentioned problems, and it is possible to reduce the number of rollers and reduce the cost of the device.
The purpose is to provide a C card reading/writing device.

[Means to solve the problem]

The IC card reading/writing device of the present invention includes a card detection means for detecting an IC card inserted into a card insertion slot, and a card detection signal from the card detection means to read and write the IC card inside the device by rotating a roller. a transport means for pulling the IC card into the card slot and ejecting the IC card into the card insertion slot;
An IC comprising: a rising contact head; and conductive contact means provided on the contact head and contacting read and write terminals of the IC card when the IC card is pulled into position.
The card reading/writing device is characterized in that the above-mentioned rollers are provided on one side edge of the IC card, and a guide plate is provided on the other side edge to prevent the IC card from jumping up. .

[Effect]

According to the above configuration, when the IC card is inserted, the insertion of the IC card is detected, the roller is rotated by the drive of the motor, and the IC card is drawn into the inside of the device. At this time, the IC card is transported by a single roller provided on one side edge, so if the IC card is warped, the other side edge may jump up, but the guide plate prevents this bounce. Since this is suppressed, the IC card can be fed normally without any problem.
