Description

[Detailed Description of the Invention] The present invention relates to the arrangement of input/output terminal groups of an electronic information card used for cash cards, ID cards, and the like.

Traditionally, magnetic cards have been the main type of information cards, but in recent years, electronic information cards with built-in IC memory have been proposed. is expected to be put into practical use. Conventional IC cards have IC memory such as PROM, and even a CPU built into a plastic card, and all input/output terminals necessary for controlling the card are placed only on the front or back side of the card, and external It is configured to exchange information with the terminal.
However, since this type of information card is small and thin, the space for arranging the input/output terminals is also small, so that the space for arranging the terminals tends to be insufficient, especially when it is desired to increase the number of terminals. Another drawback is that if a general user inserts the card with the front and back sides wrong and inserts it into an external terminal, it will not work. Furthermore, since the input/output terminal portion of the card is exposed on the card surface, poor contact due to dirt, dust, powder, etc. is likely to occur, which poses a major problem in terms of reliability. As a countermeasure, a method of cleaning the contact portion before using the card has been proposed, but this method increases the complexity and size of the external terminal device, which is disadvantageous in terms of cost.

The present invention was made to overcome the above-mentioned drawbacks, and its main points are that the input/output terminals of the IC card are arranged on both the front and back sides of the card to increase the degree of freedom in terminal arrangement. The present invention is intended to enhance convenience when using the card, and embodiments of the present invention will be described below based on the drawings.

Figure 1 shows a conventional IC card, where 1a is the card body, 2a is the input/output terminal section of the card,
The IC memory built into the card body 1a is configured to be connected to an external terminal via an input/output terminal section 2a to perform information control. Second
The figure is a plan view of one embodiment of the present invention, and FIG. 3 is a sectional view thereof. 1b is the card body, 2b is the input/output terminal section on the front side of the card body 2b, 2c is the input/output terminal section on the back side, 3 is the IC memory built into the card, and 4 is the input/output terminal section on the front side of the card body 2b.
This is a conductor that connects the IC memory 3 and the input/output terminal sections 2b and 2c. The contents of the IC memory 3 can be controlled via the conductor 4 by connecting an external terminal to at least one of the front input/output terminal section 2b and the rear input/output terminal section 2c. With this configuration, the small surface of the card body 1b becomes twice the space of the conventional card, making it possible to arrange a large number of input/output terminal groups. In addition, in FIG. 3, the input/output terminal section 2b,
By arranging 2c in symmetrical positions on the front and back, having exactly the same terminal configuration, and making each corresponding terminal an OR circuit configuration, it is possible to insert the card body 1b into an external terminal without specifying the front or back side. It can also be used for. FIG. 4 shows another embodiment of the present invention, in which 2d is an input/output terminal section, 3 is an IC memory, and 4 is an input/output terminal section.
is a conductor, and the input/output terminal section 2d is configured to be exposed on both the front and back surfaces of the card.In this case, when one surface of the input/output terminal section 2d becomes dirty and a contact failure occurs, The other surface can be used for FIG. 5 shows another embodiment of the present invention, in which 3a is an IC memory, 2e is an IC memory, and 2e is an IC memory.
An input/output terminal section for the IC memory 3a, 3b is an IC memory different from the IC memory 3a, and 4 is an input/output terminal section for the IC memory 3b, with an input/output terminal section on the front side and an input/output terminal section on the back side. The terminal portions are independent from each other, and each has the function of the card described in FIG. 1. In this case, functions that conventionally required two cards can be performed on one card, and by arranging the input/output terminals independently on the front and back, it is possible to classify the functions according to the purpose. can be done at a glance, making it suitable for composite cards.

As explained above, for IC cards that are thin, small, and require little space, by arranging the input/output terminals on the front and back sides of the card body, the overall layout of the card can be made more effective, expanding its uses. . It is also possible to eliminate the need to distinguish between the front and back sides when inserting a card into an external terminal, which is highly effective in actual use. Furthermore, it is also possible to take measures against poor contact due to dirt on the input/output terminals on the card side, which is advantageous in terms of cost.
This is important for increasing the reliability of the IC card system and promoting the spread of IC cards. Furthermore, in the case of a composite card in which one card has the functions of two different types of IC cards, it is very effective to arrange terminals on both sides of the card.
