Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an IC card reader / writer.

[Prior Art] As a conventional IC card reader / writer, Japanese Patent Laid-Open No. 64-21
The one described in Japanese Patent No. 591 is known.

As shown in FIGS. 6 and 7, this IC card reader / writer carries a casing 1 having a card insertion slot 1A and an IC card K provided in the casing 1 and inserted from the card insertion slot 1A. Card transport path 2 and IC card K
A holder 4 having a contactor 3 for contacting a contact point on the surface of the holder, which is pushed by an IC card K moving on the transport path 2 and moves together with the card K, and a holder 4 disposed along the transport path 2. The holder 4 in a slidable manner, and guides the holder 4 to bring the contact 3 into contact with the contact on the surface of the IC card as the IC card K reaches the end. And a return spring 6 that biases in the direction.

In this IC card reader / writer, when the IC card K is inserted from the insertion port 1A, the insertion is detected and the drive roller 7 on the conveying path 2 is rotated to convey the card K into the casing 1. Then, when the card K is conveyed into the casing 1, the tip of the card K is engaged with the engaging piece 4 a of the holder 4.
Then, the holder 4 is moved to the back of the casing 1 together with the card K. At this time, the holder 4 moves the transport path 2
Guided by the guide rod 5 inclined with respect to the conveyance path 2
Gradually approach the surface of the upper card K. Then, when the card K reaches the end, the contactor 3 mounted on the holder 4 contacts the contact on the surface of the card K.

In this state, the read / write processing for the IC card is performed. Then, when the processing is completed, the roller 7 is rotated in the reverse direction to transfer the card K in the opposite direction and eject it from the insertion slot 1A. Along with this operation, the holder 4 has the return spring 6
The action returns to the initial position.

By the way, as the IC card to be read / written by such a reader / writer, mainly IS cards are currently used.
An O standard IC card is used. As shown in FIG. 5, this ISO standard IC card includes two types of cards in which the positions of eight contacts C1 to C8 are different. The solid line shows ISO
The standard contact point is shown, and the broken line is the CP-8 standard contact point.

As shown in this figure, in each standard, each contact C1 to C8
Are arranged four by four in a direction (shown by Y in the drawing) orthogonal to a card insertion direction (which is a carrying direction in the reader / writer and shown by X in the drawing), and are arranged in two rows in the X direction. The contact point position of the former standard and the contact point position of the latter standard deviate by a predetermined dimension J in the Y direction, and the positional relationship between the contacts in each standard is the same.

In the past, since the above-mentioned two types of IC cards have been mainly popularized, card reader / writer manufacturers have two types of cards with different contact positions according to the IC card standards used by the user. You have to prepare a reader / writer. However, preparing the two types of products separately results in duplication of the manufacturing process and is disadvantageous in terms of cost.

Therefore, it has been considered that a reader / writer provided with 16 contacts is used as a standard product so that both standard IC cards can be used.

[Problems to be solved by the invention] However, in that case, there are the following problems.

When 16 contacts are provided, not only the number of parts increases, but there is also a contact that is not used, which is wasteful, and the space for providing the contacts needs to be doubled on the holder.

When the number of contacts is doubled, the weight of the movable part is increased and a large carrying force is required.

When the card reaches the end, the contact is pressed against the surface of the card. Therefore, immediately before the card reaches the end, the pressing force of the contact must be considered to control the card conveying force. Therefore, if the number of contacts is twice, a correspondingly large carrying force is required.

[Means for Solving the Problems] The IC card reader / writer of the present invention is made to solve the above-mentioned problems, and includes a casing, an IC card transport path provided in the casing, and an IC. A holder that has a contact for contacting a contact on the surface of the card and that is pressed by an IC card that moves on the transport path and moves together with the card, and a holder that is arranged along the transport path and slidably supports the holder. And as the IC card reaches the end, IC
A guide rod that guides the holder to bring the contact into contact with the contact on the surface of the card, and both ends of the guide rod are detachably attached to the casing to determine the position of the guide rod. Is formed, and moreover, a plurality of the positioning grooves are formed according to the standard of the IC card.

[Operation] In the IC card reader / writer of the present invention, the maker side selects the positioning groove of the guide rod according to the standard of the card used by the user at the time of shipment, and attaches the guide rod to the selected positioning groove. As a result, the position of the movement path of the holder is determined, and the position of the contactor mounted on the holder is also determined corresponding to the IC card used.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are plan views of the main part of the IC card reader / writer of the embodiment, and FIG. 4 is a side view showing the outline of the whole.

In FIG. 4, 1 is a casing having a card insertion slot 1A on the front surface, and 2 is a conveyance path 2 for conveying the IC card K inserted from the card insertion slot 1A. A front drive roller 11 and a rear drive roller 12 are arranged in the transport path 2 at a predetermined interval (interval slightly shorter than the entire length of the card K). Below the drive rollers 11 and 12, there is a card K, respectively.
Driven roller 13 for pressing the drive roller 11 and 12 against
14 are provided, and by the rotation of the drive rollers 11 and 12,
Insert the IC card K in the horizontal position and insert it from the back
It can be transported in the 1A direction.

On the side of the rear drive roller 12, a pair of mutually parallel guide rods 15 and 15 along the conveyance path 2 are arranged in the horizontal direction (strictly speaking, parallel to the surface of the IC card K on the conveyance path 2). Direction). These guide rods 15 and 15 are inclined so as to approach the conveyance path 2 from the card insertion slot 1A side to the inner side of the casing 1, and both ends are fixed to fixed shelves 1B and 1C provided in the casing 1. It is fixed.

In this case, on the upper surfaces of the fixed shelves 1B and 1C, as shown in FIGS. 1 and 2, the positioning grooves 2 are divided into two groups.
0 and 21 are formed. Positioning grooves 20, 2 for each group
There are four guide rods 1 corresponding to the numbers of both ends of the guide rods 15 and 15, and two rods are arranged on the fixed shelves 1B and 1C, respectively. The positioning grooves 20 (21) of the same group formed on the same fixed shelf 1B (or 1C) are arranged at a distance H (shown in FIG. 1) equal to the distance between the guide rods 15, 15.

The two groups are formed so as to be displaced from each other in a direction orthogonal to the guide rod 15 by a predetermined distance J, that is, a displacement dimension (shown by J in FIG. 5) between contact positions in the two IC card standards. There is. Then, FIG. 1 shows a state in which both ends of the guide rods 15, 15 are fitted and positioned in the positioning groove 20 of the first group, and FIG.
Both ends of the guide rods 15 and 15 are fitted in the positioning groove 21 of the above group and positioned.

The guide rods 15, 15 are thus selectively arranged in the first group of positioning grooves 20 or in the second group of positioning grooves 21.
It is fitted to the positioning groove 20 and 21 and is detachably fixed to the positioning grooves 20 and 21. The depth of each positioning groove 20, 21 is determined by the guide rod.
It is set to a size not less than 15 radius and less than diameter,
As a result, the upper end of the end of the guide rod 15 is positioned in the positioning groove while the end of the guide rod 15 is fitted in the positioning grooves 20 and 21.
Overhang from 20, 21. Therefore, when fixing the guide rods 15 and 15, as shown in FIG.
A fixing plate 16 is used for fixing 15 by pressing it from above.

Each of the fixed shelves 1B and 1C is provided with two protrusions 17 for positioning the fixing plate 16 while avoiding the positioning grooves 20 and 21, and one screw hole 18 for attaching the fixing plate 16 with a screw. On the other hand, correspondingly to this, the fixing plate 16 is provided with a hole 16a into which the protrusion 17 is inserted and a screw through hole 16b. Then, after fitting the ends of the guide rods 15 and 15 into the positioning grooves 20 or 21 on the fixed shelves 1B and 1C, as shown in FIG.
By fixing to the fixed shelves 1B, 1C with the guide rod 15,
Fifteen are fixed on the fixed shelves 1B and 1C.

A holder 30 having a contactor 3 on the bottom surface for contacting the contact of the IC card K is attached to the guide rods 15, 15 fixed in this way.
Is slidably supported. That is, a round hole 30a is formed in one side portion of the substantially rectangular parallelepiped holder 30, and a groove 30b having an opening facing sideways is formed in the other side portion. Then, one guide rod 15 is slidably inserted into the round hole 30a, and the other guide rod 15 is slidably fitted into the groove 30b, whereby the holder 30 is kept horizontal and the guide rod 15 is held. , 15 and are supported to move.

The holder 30 is urged toward the card insertion slot 1A by the return spring 6 arranged on the side of the round hole 30a. Further, on the lower surface of the side portion of the holder 30 opposite to the card insertion opening 1A, an engagement piece 30c with which the front end of the card K conveyed toward the back of the casing 1 is engaged is provided. Therefore, when the front end of the card K conveyed to the back is engaged with the engagement piece 30c, the holder 30 moves to the back together with the card K. The holder 30 gradually approaches the surface of the card K by the action of the guide rods 15 as it moves, and when the card K reaches the end, the contactor 3 on the lower surface of the holder 30 moves to the surface of the card K. Touch the contacts.

When the guide rods 15 and 15 are attached in the state shown in FIG. 1, the contactor 3 on the lower surface of the holder 30 is
Corresponds to the CP-8 standard IC card K contact position. Also,
When mounted in the state shown in FIG. 2, the contact groove 3 on the lower surface of the holder 30 is preliminarily positioned so that the contact 3 corresponds to the contact position of the IC card K of the ISO standard.
Positions 0 and 21 are defined.

 Next, the operation will be described.

If you want to use this card reader / writer, use it
Either the positioning groove 20 or 21 is selected depending on the type of IC card. Then, select the positioning groove 20 (or 2
Fix the guide rods 15 and 15 to 1). Then, the position of the contactor 3 on the bottom surface of the holder 30 will be changed by itself.
Corresponds to the card contact position. After that, by inserting the card K from the insertion slot 1A, the operation is performed in the same manner as the conventional one, and the reading / writing process can be performed. in this way,
By only providing the positioning shelves 20 and 21 corresponding to the respective standards on the fixed shelves 1B and 1C, it becomes possible to deal with the IC cards of both standards without increasing the number of the contacts 3 at all. Therefore, it is possible to provide a standard product that can support both standards with almost no increase in cost.

The structure of the positioning portion of the guide rod 15 is not limited to the groove as described above, and various structures can be adopted.

[Effects of the Invention] As described above, the IC card reader / writer of the present invention can be applied to the IC cards of each standard simply by selecting the positioning groove to which the guide rod is attached.
Moreover, the number of contacts can be as many as the number of contacts, and the number of parts can be minimized. Further, it is sufficient to form the positioning grooves by the number corresponding to the standard number of the IC card, and no parts for positioning the guide rod are required. Therefore, in addition to being inexpensive, it can be configured compactly,
Moreover, since the weight of the movable part does not increase, it is not necessary to increase the carrying force. Further, since the number of contacts is small, the pressing force of the contacts is also small, and from this point also, it is not necessary to increase the carrying force. Further, the position of the holder can be changed only by removing the guide rod from the positioning groove and attaching it to another positioning groove, and the position changing work can be easily performed.
