Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic card equipped with a paper-like battery for power supply.

[Technical background of the invention]

Recently, credit cards and banking cards have been equipped with wiring boards with IC chips installed inside.
In addition, electronic cards called IC cards, which have connection terminals exposed on the outer surface of the card for contacting card contact portions of card terminal devices, have come into use. This electronic card verifies the PIN number inside the card, and the PIN number registered on the card cannot be read externally, so it has a better ability to keep the PIN number confidential than magnetic cards. It has the characteristic of being extremely high.

This electronic card is used by being inserted into a card terminal device at a store, bank, etc. This electronic card is inserted into the card terminal device and its connection terminal is brought into contact with the card contact part in the card terminal device. In this state, when you enter your PIN number from the keyboard connected to the card terminal device, the entered PIN number is sent from the card terminal device to the electronic card and inputted into the electronic card as the PIN number registered on the card. A verification is performed with the entered password, and the result is sent to the card terminal [2 and displayed on the display section of the card terminal device. In addition to the PIN verification function, some of these electronic cards are equipped with a memory function that stores historical information such as card usage history, such as transaction information made with the card. The card terminal device receives transaction information entered by a store manager or a bank employee from the card terminal device through its keyboard section, and stores this transaction information in the memory section.

Conventionally, this electronic card has been known to have a single purpose such as credit, banking, etc., but recently, one card has been used for credit, banking, reservation (airline), etc. It is also being considered that the system can be used for multiple purposes, such as reservations and purchases of tickets, train tickets, reserved seat tickets, hotel accommodation tickets, etc.

This electronic card is also called a multi-purpose IC card, and its purpose is selected by the purpose selection operation key provided on the card surface, and the selected purpose is displayed on the card surface by a display panel provided inside the card. is displayed in the display window. This multifunctional electronic card is used by selecting the purpose of the card by operating the operation keys. For example, if the purpose is selected for credit, the card can be used as a credit card, or If the usage is selected for banking, this card can be used as a banking card, and if the usage is selected for reservation, this card can be used as a reservation card.

Recently, it has also been considered to provide an electronic card with a function of reading and displaying historical information (card usage history) stored in its memory. This electronic card has a history recall operation key on the card surface, and by operating this operation key, history information stored in the memory section is read out.This history information is displayed on the card surface using a display panel provided inside the card. If the electronic card is equipped with a function to read and display such history information, even if you forget the amount of accounts payable purchased using the card, it will be easy to do so. can be known.

By the way, in order to make the electronic card multi-functional by providing it with a purpose selection function, a function to read and display history information, etc., it is necessary to have the purpose selection function, history information readout and display function, etc. inside the card. However, if a normal button-type or coin-type lithium battery is used as the power source, the card becomes too thick and the electronic card cannot be inserted into the card terminal device. Because of this concern, it has been considered to use an extremely thin paper-like battery as the battery 'a'Fi battery of the electronic card. Note that, as this paper-like battery, a horizontally long rectangular one is generally known.

[Problems with background technology]

However, while the thickness of the paper battery is very thin, the paper battery has a large flat area, and the paper battery with a small area cannot be used because of its small capacity. Therefore, the paper battery is stored in a card. To do this, it is necessary to secure a large battery compartment inside the card that corresponds to the size of the paper battery. Since it is necessary to reduce the area of the board, it is desirable to arrange a plurality of m IC chips on the wiring board to accommodate the multifunctionality of the electronic card.

In other words, in order to make an electronic card multi-functional by giving it a function to select a use, a function to read and display history information, etc., it is necessary to increase the number of IC chips depending on the functions to be provided to the electronic card, or to replace it with an IC chip. However, developing a dedicated LSI chip to match the capabilities of an electronic card would require a huge amount of development costs, so there was a large demand for electronic cards with the same specifications. Since it is impossible to sieve without them, it is generally considered advantageous to combine a plurality of general-purpose IC chips to make the electronic card multi-functional. On the other hand, when a display panel and a power battery are provided inside the electronic card, if the display panel and battery are placed on a wiring board with an IC chip attached, the card becomes thick. In order to make the display panel thinner, it is necessary to place the display panel and the 'R power battery on the side of the wiring board. In this case, the size and area of the wiring board must be reduced by the space for arranging the display panel and power supply battery.

If a paper battery is used as the battery WA'R battery as described above, a large battery compartment corresponding to the size of the vapor battery must be secured inside the card. In order to make the planar dimensions the size of a credit card, the wiring board must be made smaller by the area of the paper battery, but if the area of the wiring board is reduced in this way, the layout i! Since the number of IC chips that can be attached to an i1 board is limited, multiple I
It becomes difficult to accommodate the multifunctionality of electronic cards by arranging the C-chip.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and its purpose is to increase the area of the wiring board while providing a display panel and a power paper battery inside the card. To provide an electronic card that can accommodate multi-functionalization of the electronic card by arranging a plurality of IC chips on a wiring board.

[Summary of the invention]

That is, in the present invention, a battery storage section is provided on the lower side of a display panel that is arranged to face a display window section provided on the card surface, and a paper-like battery for power supply is stored in this battery storage section. By arranging the paper battery below the display panel in this way, there is no need to secure separate space for the display panel and paper battery, so the area of the wiring board can be increased accordingly. therefore,
By arranging a plurality of IC chips on a wiring board, it becomes possible to support multifunctional electronic cards.

By inserting the electronic card into the terminal 5A in this position, the connection terminals 5.5 on the bottom side of the card can be brought into contact with the card contacts 1 to 1 provided on the bottom of the card insertion section of the terminal device. In other words, if the connection terminal, application selection key, and display section are provided on the same side of the card, when selecting the application, the card is turned over so that the application selection key and display section are facing upward, and when the card is inserted into the terminal device, the card is turned over. You have to turn it over so that the connection terminal is facing down, but if you provide the application selection key 2 and display section 4 on the top side of the card and the connection terminal 5.5 on the bottom side of the card as described above, you can select the application. Since it is not necessary to turn over the card each time when inserting the card into the card terminal device and when inserting the card into the card terminal device, selection of the application and insertion into the card terminal device can be easily performed. Furthermore, since this electronic card can be inserted into the card terminal device with the display section 4 facing upward, it is possible to reconfirm the selected purpose displayed on the display section 4 when inserting the electronic card into the card terminal device. Even if you select the wrong application, you can easily detect this when inserting the card into the card terminal device.
If the card is sent to the card terminal with the wrong purpose selected
This can prevent the device from being inserted into the

When the electronic card is inserted into the terminal device and its connecting terminal 5.5 is brought into contact with the card contact section of the terminal device, a reset signal is sent from the terminal device to the card, and the CPU 70 is reset (however, the memory and operation section (The usage data stored in the card 72 and the usage display on the display section 4 are left as they are), and the answer is returned from the card to the terminal device. When this answer is sent to the terminal device, the TC code is sent from the terminal device to the card, and the usage data stored in the storage/arithmetic unit 72 is sent from the card to the terminal device. The terminal device checks this usage data and, if the usage data is suitable, displays a password input instruction on the display section of the terminal device.

Then, when the card owner inputs the password from the keyboard section connected to the card terminal device, this input information (password) is sent from the terminal II to the card. This input information is sent to the password verification section 74a of the EEP-ROM 74, and the password verification section 74a of the EEP-ROM 74
The card is compared with the PIN stored in the card 4a, and if both match, a match signal is sent, and if they do not match, a mismatch signal is sent from the card to the terminal device. If the PIN numbers match or do not match, the display on the terminal will indicate whether the transaction is OK or NG.
will be displayed as .

Here, if the transaction is OK, the store clerk inputs transaction information such as the amount of the product to be purchased by the customer (card holder) into the terminal device from the keyboard section. Transaction information entered into this terminal device is sent from the terminal device to the card, and the card transfers this transaction information to the EEP-R.
It is sent to the balance memory 174b of the OM74 and stored in its credit memory area. This is the same when using an electronic card for banking, reservations, etc. For example, if you select the purpose of the card for banking and use it as a banking card, the information sent from the terminal device (deposit deposit information) Withdrawal information) is stored in the banking storage area of the balance storage unit 74b, and when the purpose of the card is selected for reservation and used as a reservation card, the information sent from the terminal device (reservation information, amount information, etc.) It is stored in the reservation storage area of the balance storage section 74b.

Note that the card storing transaction information and the like is removed from the terminal device after the operation of the terminal device is completed.

Further, the electronic card has a function of displaying fat layer information such as transaction information stored in the balance storage section 74b on the display section 4, by turning on the power switch 60 and operating the use selection key 2. When the history recall key 3 is operated with the use of the card selected, for example, for credit, the information stored in the credit storage area is read out from the balance storage section 74b in the order in which it is stored and displayed on the display section 4 in sequence. When the history recall key 3 is operated with the card usage selected as banking, the information stored in the banking storage area of the balance storage unit 74b is sequentially displayed on the display unit 4, and the card usage is set to reservation. When the history recall key 3 is operated with the balance storage section 74b selected, the information stored in the reservation storage area of the balance storage section 74b is sequentially displayed on the display section 4. Therefore, according to this electronic card, even if you forget the amount of accounts payable, deposit amount, reservation details, etc. that were purchased using the card, you can recall the history information stored in this card at will and check the usage history of the card. You can learn by use.

The display of the above history information may be configured to change automatically at fixed intervals (1 to 2 seconds), or the next information may be displayed each time the history call key 3 is operated. It's okay.

However, in this electronic card, as mentioned above,
Since the space under the liquid crystal display panel 40 is used to store the Nai vapor battery 50 in this area, there is no need to secure a separate storage space for the power supply battery, and therefore the wiring board can be saved by that amount. Since the unit 20 can be enlarged to provide more room for routing wiring on the board surface and for arranging IC chips, etc., the wiring board unit 20 can have multiple IC chips.
28 can be arranged to support multi-function electronic cards.

Moreover, in this electronic card, since the paper battery 50 is held in the battery holder 51 and inserted into the card as described above, the paper battery 50
The paper battery 50 can be inserted into the card without any external force being applied to it, so there is no need to worry about bending the paper battery 50, which is weak in strength, when inserting the paper battery 50 into the card. Furthermore, since the battery holder 51 is guided by the lower surface of the liquid crystal display panel 40 and inserted into the card, there is no need to provide a guide part for the battery holder 51 on the lower side of the liquid crystal display panel 40. By bringing the lower surface of the liquid crystal display panel 40 into direct contact with the upper surface of the battery holder 51, the card can be made thinner.

Furthermore, in the above embodiment, the wiring board unit 20 is a two-layer TP structure consisting of the main wiring board 21 on which the IC chips 25, 26, 27, and 28 are attached, and the sub wiring board 22 overlapping the main wiring board 21. Since the key contacts 32, 32 of the application selection key 2 and the history call key 3 are provided in the main wiring board 21, the IC chips 25, 26, 27, 28 can be housed in the openings 29, 29 of the main wiring board 21 to make the card thinner. Although it is a compact device, it is possible to freely select the positions of the key contacts 32 and 32 and provide the application selection key 2 and the history call key 3 at any desired location. In other words, when using a single wiring board, if an opening is provided in the distribution board and an IC chip is housed within this opening, the key contact point formation position is limited to the part without the opening, so the key position cannot be changed arbitrarily. However, if the sub wiring board 22 is stacked on the main wiring board 21 as in the above embodiment and the key contacts 32.32 are provided on this sub placement board 22, the key contacts 32.32 can be As shown in Figure 4, the main layout
It is also possible to provide the IC chips 25, 26, 27, 28 above the IC chip accommodating opening 29 of the l plate 21.
Key contact 32.32 can be placed at any position regardless of the placement position.
Therefore, the positions of the application selection key 2 and the history call key 3 provided on the card surface can be arbitrarily selected.

In the above embodiment, the application selection key 2 and the history call key 3 are connected to the key contacts 32, 32 formed on the wiring board unit 20 and the movable key contacts 3 provided on the top sheet 11b.
2a, the application selection key 2 and history call key 3 may be of a capacitive type or a touch type, and the wiring board unit 20 may be only the main wiring board 21. However, if the wiring board unit 20 is made up of only the main arrangement board 21, the key contacts 32, 32 must be provided avoiding the IC chip accommodating opening 29° 29 of the board 21 as described above, but the application selection key 2 and If the history recall key 3 is of a touch type, a touch contact point may be provided on the top surface of the card body 1, so the application selection key 2 and the history recall key 3 can be provided at any position.

Further, in the above embodiment, a multi-purpose electronic card having a purpose selection function and a history information reading and displaying function has been described. It can be applied to single-purpose electronic cards with a display function, and is not limited to those with a purpose selection function or history information readout and display function. It goes without saying that the present invention can be widely applied to electronic cards equipped with a display panel and a paper-like battery for power supply inside the card, such as an electronic card that functions as a small electronic calculator by arranging keys for arithmetic operations.

〔Effect of the invention〕

This invention provides a battery storage section on the lower side of a display panel that is placed opposite to a display window provided on a card surface, and stores a paper-like battery for power supply in this battery storage section. If the paper battery is placed below the display panel, there is no need to secure separate space for the display panel and paper battery, and the area of the wiring board can be increased accordingly. Although the card has a display panel and a paper-like battery for power supply inside the card, the area of the wiring board is increased and multiple IC chips are placed on this wiring board to accommodate the multifunctionality of the electronic card. I can do it.
