Description

Description: TECHNICAL FIELD The present invention relates to a flexible cable body for connecting a control circuit of an IC card reader / writer and an IC card. [Prior Art] At present, two types of IC cards, an upper position type and a lower position type, have become international standards due to differences in the arrangement positions of IC contact positions. Here, an IC card connection structure that can handle both positions is required so that the IC card reader / writer can handle such two types of IC cards. FIG. 4 is a perspective view showing a conventional example of this type of connection structure.
No. 26090. In the figure, reference numeral 1 denotes an IC card, and an upper position type IC card has a contact point 1a at a position U, and a lower position type IC card has a contact point 1a at a position L. Reference numeral 2 denotes a contact, which has a structure capable of sliding in the direction of the arrow. According to the above configuration, the contact 2 is slid with respect to the upper and lower positions of the IC contact position on the IC card 1 to make contact with the contact 1a at both contact positions. [Problems to be Solved by the Invention] However, according to the conventional technology having the above-described configuration, a person visually determines whether the IC contact position of the IC card is the upper position or the lower position and moves the contact. Must-have. Therefore, there is a problem that the control circuit of the IC card reader / writer cannot exchange data with the IC card if the IC card reader / writer slides to an incorrect position. Furthermore, when the slide of the contact is stopped halfway, the IC contact
There is a problem that the IC chip in the IC card is destroyed because the voltage for the card is output. In view of the above problems, the present invention obtains a configuration in which connection is performed with the position of a contact fixed, eliminating the occurrence of sliding to an erroneous position or an intermediate position due to movement of a contact, and transferring data. It is an object of the present invention to realize an IC card connection structure which is reliable and does not cause breakage of an IC chip in the IC card. [Means for Solving the Problems] In order to achieve the above object, the present invention provides an IC contact position having an upper position or a lower position, wherein the upper position and the lower position are in contact with two types of IC cards having the same number of contacts. In addition, in the flexible cable body detachable from the control circuit of the IC card reader / writer, the flexible cable body has the same number of contact pins as the total number of the contacts at the upper position and the lower position, and is provided at any of the contacts at the upper position and the lower position. A contact capable of contacting the contact pin, the contact being provided, and having a half of the number of signal transmission conductors of the contact pin of the contact, one end of each conductor being one end of the contact at the upper position side of the contact; Contact pins and the lower position corresponding to the arrangement of the contact pins And a contact portion connected to both of the one contact pin on the other side, and the other end of each conductive wire is connectable to the control circuit. [Operation] With the configuration described above, according to the present invention, when the IC card is set at a predetermined position, the contact pin of the contact makes contact regardless of the upper position or the lower position of the IC contact position. The signal transmitted from the contact at the upper position side or the lower position side of the IC card is transmitted to the control circuit via the conductor of the flexible cable. Embodiment An embodiment will be described below with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of the present invention. In the figure, reference numeral 3 denotes a control circuit of an IC card reader / writer, and 1 denotes an IC card. FIG. 2 is a plan view showing the structure of the IC card 1. In FIG. 2, the IC contact position is at a position U for an IC card of an upper position type.
The lower position type IC card has a contact 1a at position L. Returning to FIG. 1, reference numeral 4 denotes a contact on the IC card reader / writer side. The contact 4 has a contact pin 5 for contacting all of the contacts 1a arranged in the upper position U and the lower position L of the IC contact position. ing. Here, the contact 4 has a maximum of 16 contact pins 5. The upper position U and the lower position L of the IC contact position each have eight contacts 1a. However, each of the two contacts 1a is unused, so that a total of 12 contacts 1a may be provided. Reference numeral 6 denotes a flexible cable for connecting the contact 4 to the control circuit 3 of the IC card reader / writer, and reference numeral 7 denotes a connector which is mounted on the control circuit 3 of the IC card reader / writer and into which the flexible cable 6 is inserted. FIG. 3 is a plan view showing the details of the configuration of the flexible cable 6, and reference numeral 8 denotes a soldering portion between the contact 4 and the contact pin 5. On the other hand, 9 is a connector 7 of the control circuit 3.
And has a contact for one signal. Reference numeral 10 denotes a copper foil conductor. The conductor 10 is connected to each of the soldering portions 8 on the upper position side and the lower position side, and is converged and connected to the contact portion 9 for one signal. With the above configuration, when the IC card 1 is set at a predetermined position of the IC card reader / writer, regardless of whether the IC contact position of the set IC card 1 is the upper position U or the lower position L, the position of the IC card 1 for both positions is set. The contact 4 having the contact pins 5 collectively makes contact with the contact 1a on the upper position side or the lower position side of the contact pins 5. The signal of the IC card 1 transmitted from the contact 1a at the upper position U or the lower position L to the contact 4 is transmitted to the conductor 10 of the flexible cable 6.
Converges on the contact portion 9 for one signal and is transmitted to the control circuit 3. [Effects of the Invention] As described above, the present invention provides an IC contact position which is an upper position or a lower position, where the upper position and the lower position come into contact with two types of IC cards provided with the same number of contacts. In a flexible cable body detachable from the control circuit of the reader / writer, the flexible cable body has the same number of contact pins as the total number of contacts in the upper position and the lower position, and contacts the contact pins with any of the contacts in the upper position and the lower position. A contact that has been enabled, and the contact is provided, and has a half of the number of contact pins of the contact for signal transmission, and one end of each conductor has one contact pin on the upper position side of the contact and one of the contact pins. One contact on the lower position side corresponding to the contact pin arrangement In addition to the connection to both the pins, the other end of each conductor has a contact portion connectable to the control circuit. Thus, the control circuit of the IC card reader / writer can be connected to both the IC card having the contact at the upper position and the IC card having the contact at the lower position in a state where the position of the contact is fixed. An IC that eliminates the possibility of sliding to an erroneous position or an intermediate position due to the movement of contacts, ensures data transfer, and does not cause breakage of an IC chip in an IC card.
This has the effect of realizing a card connection structure. Further, the flexible cable used in the present invention connects one connection pin on the upper position side of the contact and one connection pin on the lower position side with one conductor, and connects one end of each conductor to the IC card reader / writer. Control circuit, the control circuit can control the processing for the IC card connected to the connected contact without identifying whether the IC card is connected to the upper position or the lower position. Therefore, the load on the control circuit can be reduced, and the processing speed can be increased.
