DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card reader / writer for reading (reading) information recorded on an IC card and writing (writing) information on the IC card, and particularly to an external terminal of the IC. The present invention relates to a technique for stabilizing a contact action of a read / write device.

[0002]

2. Description of the Related Art A conventional IC card reader / writer is known from Japanese Patent Publication Nos. 2593143 and 2775343. The I disclosed in these publications
The configuration of the C card reader / writer is generally as follows.
The IC card inserted into the apparatus is transported in one direction along the transport path, and engages with the engaging piece of the holder at the standby position during the transport, and as the transport is further performed, the holder is engaged. It is pushed to the read / write position by the IC card via the mating piece, and the read / write of the IC card is performed by the contact mounted on the holder. The holder is
As the IC card engages with the engagement piece and moves to the read / write position, it is guided by the guide and approaches the IC card.
Read / write is enabled by contacting the external terminal C. When reading / writing is completed, the IC card is conveyed in the reverse direction and discharged out of the apparatus, and the holder follows the movement of the IC card by the return spring, and returns to the standby position while leaving the conveyance path. In such a conventional IC card reader / writer, the IC card inserted into the device and reaching the read / write position stops while resting on a plate-shaped receiving member, and the IC card is placed on the flat upper surface of the receiving member. Is supported from the back side, and the contact is configured to contact the external terminal with an appropriate pressure.

[0003]

Since the receiving member of the conventional IC card reader / writer has a plate-like shape, the area of the IC card being conveyed to the receiving member in sliding contact with the receiving member is large, and frictional resistance is generated between the two. In addition, smooth conveyance is hindered, and the IC card is scratched by the receiving member. Further, since the card thickness of the IC portion is smaller than that of the other portions and the degree of the influence of the pressure by the contacts is large, the elements built in the IC are liable to be damaged such as being deformed or crushed. Accordingly, the present invention is to provide an IC card reader / writer in which the frictional resistance between the IC card and the receiving member is reduced, smooth conveyance and prevention of scratches are prevented, and damage to elements in the IC is avoided. The purpose is.

[0004]

According to the present invention, there is provided an IC card reader / writer comprising: a transfer path provided to transfer an IC card inserted from one direction to at least a read / write position; and an IC along the transfer path. It has a transport mechanism for transporting the card in one direction and a reverse direction reverse to the one direction, and an engagement piece projecting into the transport trajectory of the IC card transported on the transport path, and the IC card is engaged with the engagement piece. By being pushed by the IC card through the engagement piece from the matching standby position,
A holder that moves to at least the read / write position together with the IC card, supports the holder movably along the transport path, and inserts the holder into the IC as the holder moves from the standby position to the read / write position.
A guide that guides the card closer to the card; a contact mounted on the holder, which contacts the external terminal of the IC of the IC card when the holder moves to the read / write position and approaches the IC card; An IC card reader / writer, comprising: a receiving member disposed to face a contact of a moved holder with the IC of the IC card sandwiched between the IC and receiving and supporting the IC; and an urging member for returning the holder to a standby position. Is characterized by having a roller rotatable in the direction of transport of the IC card and contacting a portion corresponding to the IC when the IC card moves to the read / write position.

[0005] The basic operation of the IC card reader / writer of the present invention is as follows. When the IC card is inserted from one direction, the IC card is transported in one direction along the transport path,
It comes into contact with and engages with the engaging piece of the holder at the standby position. Further, as the IC card is conveyed, the holder is guided by the guide while being pushed by the IC card via the engagement piece, and moves to the read / write position. At this read / write position, the roller of the receiving member receives and supports the back surface of the IC portion of the IC card, and the contact contacts the external terminals of the IC to enable reading / writing. When reading / writing is completed, I
The C card is discharged out of the apparatus by being transported in the reverse direction. By this discharging operation, the holder is moved by the urging member to the I position.
It follows the movement of the C card and returns to the standby position while leaving the transport path.

According to the present invention, the roller of the receiving member rotates by receiving the back surface of the IC card to be conveyed, contacts the back surface of the IC portion of the IC card that has reached the read / write position, and contacts the external terminal. It is supported by the contact pressure of the contact. Also,
When the card is ejected and the IC card is separated from the read / write position, the rollers of the receiving member rotate with the conveyance of the IC card. Thus, the IC card is prevented from sliding on the receiving member, the frictional resistance is greatly reduced, smooth conveyance is performed, and the IC card is not damaged by the receiving member. When the IC card is in the read / write position, the roller of the receiving member receives and supports the IC portion of the IC card, so that the contact pressure of the contact with the external terminal is generated and the contact pressure is optimized.

Further, in the present invention, it is preferable that the position where the roller comes into contact with the IC card is separated from a portion corresponding to an element incorporated in the IC. The element of the IC is usually built in the center of the IC, and when the element is sandwiched between the contact and the roller, the element is easily deformed or crushed and easily damaged. However, by separating the position where the roller contacts the IC card from the portion corresponding to the element, the element is not damaged.

According to the present invention, it has been described that the contact pressure of the contact with the external terminal of the IC is optimized by the roller of the receiving member receiving and supporting the IC portion of the IC card. Fluctuations in the contact pressure of the contacts are inevitable due to assembly errors or errors in the thickness of the IC card. Therefore, it is preferable to make the roller elastically displaceable in the direction in which the contact contacts the external terminal of the IC so that the contact pressure of the contact with the external terminal is not excessively increased. Therefore, in the present invention, it is preferable that the roller of the receiving member is elastically displaceable in a direction in which the contact contacts the external terminal of the IC of the IC card. Specific means for displacing the roller in this way include:
The roller is formed of an elastic material such as rubber, and the roller is elastically deformed by the pressure of the contact, the roller shaft is bent by the pressure of the contact, and the roller shaft is attached to the contact by a spring member. For example, there is a means that the entire roller shaft moves against the urging force of the spring member following the pressure of the contact.

The receiving plate 51 is formed with a concave portion 51a for preventing the engaging piece 41 moving together with the holder 20 from interfering.

The configuration of the IC card reader / writer according to one embodiment has been described above. Next, the operation of the present apparatus will be described in terms of front insertion when the card K is inserted from the front insertion slot 12 and conveyed rearward, and rear insertion. The description will be made separately for rear insertion when the card K is inserted from the insertion slot 13 and transported forward.

(A) Front Insertion-FIGS. 6 (a) to 6 (c) When the card K is inserted from the front insertion slot 12, the card sensor detects this and the transport motor 17 is driven, and the front and rear transport roller pairs 14A , 14B rotate in the backward transport direction. Next, the card K is transferred to the transport roller pair 1.
4A and 14B, the sheet is conveyed rearward along the conveying path 11. Then, as shown in FIG.
The rollers 52A and 53A of the receiving member 50
, And is further conveyed while rotating these rollers 52A and 53A, and abuts on the lower portion 41b of the engaging piece 41 of the holder 20 at the standby position. Since the rotation of the engagement piece 41 in the direction of the arrow P is restricted, the engagement piece 41 is engaged with the card K, and as the card K is further conveyed, the holder 20 is moved.
Is guided by the guide holes 21A, 21B and 22A while being pushed by the card K via the engagement piece 41, and approaches the card K,
As shown in FIG. 6B, the read / write position is reached.
When the holder 20 and the card K reach the read / write position, the transport motor 17 stops. At the read / write position, the contact 31 of the holder 20 comes into contact with the external terminal 3 of the card K on the rollers 52A and 53A of the receiving member 50, thereby enabling reading / writing. When reading / writing is completed, the transport motor 17 rotates in the reverse direction, and the card K is transported forward, and is discharged to the front insertion slot 12. By this discharging operation, the holder 20 follows the movement of the card K by the return spring 42, and returns to the standby position while separating from the transport path 11.

In this embodiment, the card K can be discharged to the rear insertion slot 13. In this case, the card K is further conveyed from the read / write position. Holder 20
While the guide holes 21A, 21B, 2
It is guided by 2A, moves backward, rises, and reaches the evacuation position. Then, as shown in FIG.
The card 1 is removed from the card K, and the card K is further conveyed backward and discharged to the rear insertion slot 13. Even during this conveyance, the rollers 52A and 53A of the receiving member 50 are in contact with the back surface of the card K and are rotated with the conveyance. When the engagement piece 41 is disengaged from the card K, the return spring 42 receives the force of returning the engagement piece 41 together with the holder 20 to the front standby position. However, since the engagement piece 41 is in contact with the card K, it moves forward. Movement is regulated. In this state, the holder 20 has the guide holes 21A, 21B, 2
Although the engaging piece 41 presses the card K by going to the lowermost portion of the 2A, the frictional resistance is reduced by the roller 45, and the card K is smoothly discharged to the rear. Further, there is no possibility that the surface of the card K is damaged by the engagement piece 41.

(B) Rear Insertion--FIGS. 7A and 7B When the card K is inserted from the rear insertion slot 13, the card sensor detects this and the transport motor 17 is driven, and the front and rear transport rollers Each drive roller 15 of the pair 14A, 14B rotates in the forward transport direction. As shown in FIG. 7 (a), the card K abuts on the engagement piece 41, from which the further card K
7 is pressed by the card K while the holder 20 is at the standby position, the engagement piece 41 having received the insertion operation of FIG.
(B) is rotated in the direction of arrow Q, and as shown in FIG.
Evacuate from As a result, the card K passes through the engagement piece 41 while rotating the roller 45 contacting the front surface and the rollers 52A and 53A of the receiving member 50 contacting the back surface. Next, the card K is moved to the rear conveying roller pair 14B.
When the card K is completely passed through the engagement piece 41, the engagement piece 41 is returned to the return spring 42.
Returns to the original engagement position. Subsequently, the card K is transported forward, delivered to the front transport roller pair 14A, and discharged to the front insertion slot 12.

The IC card reader / writer of the present embodiment uses the rollers 52A, 5 rotatable in the transport direction of the card K to move the IC2 portion of the card K reaching the read / write position.
It is configured to receive and support by 3A. For this reason,
When the card K is transported, the rollers 52A and 53A rotate as the card K is transported when the card K is transported to the read / write position, when the card K is separated from the read / write position, or when the card K passes through the read / write position. As a result, the frictional resistance applied to the card K during the transfer is greatly reduced, and the transfer is performed smoothly, and the card K is not damaged by the receiving member 50. When the card K is in the read / write position, the receiving member 5
The rollers 52A and 53A of the card K receive and support the IC2 portion of the card K, so that the contact 31
And the contact pressure is optimized.

Further, since the position of the rollers 52A, 53A in contact with the card K is separated from the portion corresponding to the element 2a built in the IC 2, that is, from the back surface of the element 2a, the contact 31 is connected to the external terminal 3. The pressure at the time of contact is not directly received by the element 2a. Therefore, the element 2a is not damaged at the time of reading / writing, and the life of the card K is extended.

Further, since the rollers 52A and 53A are arranged at positions for receiving the front row and the rear row of the external terminal 3, respectively, when the contactor 31 comes into contact with the external terminal 3, the reaction force generating the contact pressure is reduced. The contact is directly reflected on the contact 31 from the rollers 52A and 53A with the external terminal 3 interposed therebetween. As a result, the contact state is more stabilized.

Next, a modified example of the roller of the receiving member according to the above embodiment will be described. The roller 60 shown in FIG.
It is made of elastic rubber or the like, and is elastically deformed by being pushed by the card K when the contact 31 comes into contact with the external terminal 3. According to the roller 60, for example,
Even if the contact pressure of the contact 31 against the external terminal 3 becomes excessively high due to a dimensional error of a part, an assembly error, an error of the thickness of the card K, or the like, the error is buffered by the elastic deformation of the roller 60. The appropriate contact pressure is always maintained.

As shown in FIG. 11, the card K can be received by one roller 61. This roller 61
Is formed of an elastic material such as rubber, but has a larger diameter than the rollers 52A, 53A, and 60, and is adapted to receive the back surface of the central portion of the IC 2 in which the element 2a is built. The roller 61 has a relatively large diameter to receive the IC 2 and has elasticity so as not to damage the element 2a.

The action of buffering the contact pressure of the contact 31 is achieved by not only using a roller made of an elastic material but also making the roller shaft bend by the contact pressure and supporting the roller shaft so that it can move vertically. Means are such that the spring member biases the contact 31 in the direction (upward), and the entire roller shaft follows the pressure of the contact 31 and moves against the urging force of the spring member.

[0031]

As described above, according to the present invention,
The IC part of the IC card that has reached the read / write position is
Since the roller is supported and supported by a roller that is rotatable in the direction in which the C card is transported, frictional resistance is reduced when the IC card is transported, and smooth transport and prevention of scratches are achieved.
