Example 4

  Examples of the present invention will be described below.

(Display card)
FIG. 1 shows the configuration of the display card 60. The display card 60 is, for example, a plastic card provided with an electromotive coil 20, an IC chip (second chip) 30, and a display device 40 (including a controller 42).

  The electromotive coil 20 is configured by arranging a conductive wire on the back surface of the base material 12 so as to circulate a plurality of times along the outer edge thereof. Both ends of the conducting wire are connected to the IC chip 30 and the display device 40 (including the controller 42; the same applies hereinafter). An induced electromotive force is generated in the electromotive coil 20 due to a change in the surrounding magnetic field. The generated induced electromotive force is supplied to the IC chip 30 and the display device 40.

  The IC chip 30 reads information recorded on a chip built in the non-contact card 70. The IC chip 30 updates the display of the display device 40 via the controller 42 based on the read information. As an example of the IC chip 30, an IC chip that conforms to NFC is adopted. It is assumed that the chip (first chip) of the non-contact card 70 conforms to Felica. It is possible to use the two cards simultaneously by superimposing the display card 60 on the non-contact type card 70.

  The display device 40 has a display area 40a and displays information transmitted from the IC chip 30 thereon. In this embodiment, as the display device 40, for example, electrophoresis type electronic paper that does not require electric power except for rewriting is employed. Since power is required only when information displayed on the electronic paper is rewritten, information is displayed in the display area 40a even when the electromotive coil 20 does not supply power.

  When the display card 60 is placed on the contactless card 70 and is held over an external device (for example, a ticket gate), an induced electromotive force is generated in the electromotive coil 20 due to a magnetic field change generated by the external device. This induced electromotive force is supplied to the IC chip 30 and the display device 40. The IC chip 30 and the display device 40 operate to display information read by the IC chip 30 on the display device 40.

  The display card 60 is a non-contact type card like the non-contact type card 70. In the present specification, the card from which information is read is referred to as “non-contact card 70”, and the card that reads and displays information is referred to as “display card 60” instead of “non-contact card”. Differentiate cards.

  FIG. 2 shows processing of the IC chip 30. FIG. 2A shows a standard process. The process starts when the display card 60 is held over an external device and an induced electromotive force is generated in the electromotive coil 20 (step 31).

  The IC chip 30 reads information recorded on a chip built in the non-contact type card 70 and acquires information (step 33). Reading of information from the non-contact type card 70 (for example, Suica (registered trademark)) may be performed by a known method described in Non-Patent Document 1, for example.

  Here, the information read from the non-contact type card 70 is, for example, a record of getting on and off the railway, and a balance of the charge amount. The contactless card 70 updates information each time it is held over an external device (for example, a ticket gate). Updated information is read.

  The IC chip 30 determines whether the read information is the same as the previous time (step 34). For this reason, the read information is recorded in the IC chip 30, and the record is updated when it is not the same as the previous time. Immediately after the start of step 31, the information read last in the previous process is recorded on the IC chip 30. In addition, as the read information, not only the immediately previous one time but also a plurality of times of history can be recorded. The history recording will be described in detail in the fourth embodiment.

  If the read information is the same as the previous time, the IC chip 30 reads the information again. If not, the IC chip 30 displays the information on the display device 40 (step 35) and reads the information again. Thereby, when the information recorded on the chip incorporated in the non-contact card 70 is updated, the display of the display device 40 is updated.

  Here, the non-contact type card 70 widely used as a commuter pass encrypts and holds a lot of information. Among them, information including the balance of the charge amount is held without being encrypted and can be read.

  Although the end of the process is not shown in FIG. 2A, the process ends when the display card 60 is separated from the external device and the induced electromotive force of the electromotive coil 20 disappears.

  FIG. 2B shows an alternative process for the IC chip 30. When the alternative process is compared with the standard process, the process waits for a predetermined time immediately after the start (step 32), and does not determine whether the read information is the same as the previous one (step 34). Is different. Steps 31, 33 and 35 are identical.

  In this alternative process, the display card 60 and the contactless card 70 are simultaneously held over an external device, and the time required for the information recorded in the contactless card 70 to be updated by the external device is substantially constant. It is a premise. It waits for a predetermined time (for example, 1 second) that is slightly longer than the predetermined time (step 32), and then reads the updated information (step 33) and causes the display device 40 to display the information (step 33). 35). The display of the display device 40 is updated by acquiring information only once.

  If the predetermined time is set longer, the information recorded on the non-contact card 70 is reliably updated at the time of information acquisition. On the other hand, when the predetermined time has elapsed, there is a possibility that the display card 60 is separated from the external device and there is no induced electromotive force, so that information cannot be acquired. Regarding this problem, the user is informed of a predetermined time and is surely held over an external device. The display card 60 is provided with a capacitor for storing induced electromotive force, and after a predetermined time, the information updated by the power from the capacitor is read. Other measures for executing (Step 33) are conceivable.

  In the alternative process, it is also possible to determine whether or not the read information is the same as the previous time between steps 33 and 35 and display the information on the display device 40 only when it is not the same. .

The support member 16 is fixed by being overlapped with the upper side, the lower side, and the right side of the base material 12 covered with the cover 14 at the upper side, the lower side, and the right side, respectively. Thereby, an accommodation space for inserting and removing the non-contact type card 70 from the left of the support material 16 is formed between the base material 12 and the support material 16. When the non-contact type card is received, at least the center of the non-contact type card is exposed from the fluoroscopic port 16a, so that the user visually observes information recorded on one surface of the non-contact type card through the fluoroscopic port 16a. Can do.

  When the non-contact type card 70 is accommodated in the card case 1, the display card 60 and the non-contact type card 70 are arranged to overlap each other. When the contactless card 70 is used while being held in the card case 1 over an external device such as a ticket gate, the information read by the IC chip 30 is displayed on the display device 40.

  In this embodiment, it is considered that the contactless card 70 is often a railroad card such as a commuter pass. However, even if it is other, the information display by the display card 60 is useful. Moreover, when it is a railway card, it is preferable that the information is a balance of the charge amount. Thereby, the balance of the charge amount recorded on the contactless card is displayed on the display device 40, and the balance can be known.

  The present embodiment shows a configuration of a card case 1 different from the first embodiment. The other points are the same as in the first embodiment, and detailed description thereof is omitted.

  FIG. 4 shows the configuration of the card case 1 in a state in which the non-contact type card 70 is accommodated. 4A and 4B show the configuration of the cross section of the card case 1 (cross section taken along the line S-S in FIG. 4C), and FIG. 4C shows the inner surface of the card case 1 (FIG. 4B).

  When the card case 1 is expanded, the shape shown in FIG. 4B is obtained, and information can be viewed through the fluoroscopic openings 14a and 16a (see FIG. 4C). Usually, the card case 1 is folded and information cannot be visually observed. This is intended for users who do not want other users to know the displayed information (for example, who wants to protect the privacy of personal information).

  In this embodiment, a display card 60 having a power source is used. The other points are the same as in the first embodiment, and detailed description thereof is omitted.

(Display card)
FIG. 5 shows the configuration of the display card 60. The display card 60 is obtained by adding a power supply 50, a switch 52, and a charging terminal 56 to the configuration shown in FIG.

  The power supply 50 is assumed to be ultra thin with a thickness of about 0.4 mm. It can be incorporated into the display card 60.

  The switch 52 controls power supply from the power supply 50 to the IC chip 30 and the display device 40. A contact 54 is provided on a line for supplying power from the electromotive coil 20 to the IC chip 30 and the display device 40, and a switch 52 is provided on a line connecting the power supply 50 and the contact 54.

The structure of an SS line | wire cross section is shown. 6 (A) and 6 (C) are the same as FIGS. 3 (A) and 3 (C) in the first embodiment. FIG. 6B shows a switch button 52a added to FIG. 3B in the first embodiment.

  When the switch button 52a is not operated, the switch 52 is disconnected and the card case 1 is used as in the first embodiment. When used over an external device such as a ticket gate, information can be displayed on the display device 40 without operating the switch button 52a.

  When the switch button 52a is operated (pressed), the switch 52 is connected, power is supplied from the power source 50 to the IC chip 30 and the display device 40, and the card case 1 is not held over an external device, but from the contactless card 70. Information can be read and displayed on the display device 40. For example, immediately after exchanging the non-contact type card 70, the balance of the charge amount recorded on the non-contact type card 70 after the exchange can be displayed by operating the switch button 52a. Note that reading of information from the non-contact type card 70 is also performed when the card case 1 is held over an external device, as in the first embodiment. The electric power at that time may be from the electromotive coil 20 or from the power source 50.

  The display card 60 can be removed from the card case 1 and an external power supply can be connected to the charging terminal 56 to charge the power supply 50. In Example 1, it was not necessary to take out the display card 60 from the card case 1, and the display card 60 could be enclosed in the cover 14. In this embodiment, in order to enable charging, the battery can be taken out without being enclosed.

  In this embodiment, a display card 60 that can be connected to an external power source (battery 80) is used. The other points are the same as in the third embodiment, and detailed description thereof is omitted.

(Display card)
FIG. 7 shows the configuration of the display card 60. The display card 60 is obtained by adding a switch 52 and an external terminal 58 to the configuration shown in FIG. The IC chip 30 has a storage capacity larger than that of the non-contact card 70. The memory of the IC chip 30 is nonvolatile. The display device 40 is a liquid crystal display.

  The switch 52 controls power supply from the external power source (battery 80) to the IC chip 30 and the display device 40 via the external terminal 58. A contact 54 is provided on a line for supplying electric power from the electromotive coil 20 to the IC chip 30 and the display device 40, and a switch 52 is provided on a line connecting the external terminal 58 and the contact 54.

  In this embodiment, since the battery 80 is used, the display card 60 has a sufficient power source. A device that requires power for display, such as a liquid crystal display, can be used. Further, information can be read from the non-contact card 70 without using the electric power of the electromotive coil 20. In the third embodiment, as long as sufficient power can be supplied from the power supply 50, the same operation as that of the present embodiment can be performed. The case of having a sufficient power source will be described in this embodiment, not in the third embodiment.

  The external terminal 58 is provided in the vicinity of the lower right end portion of the display card 60 and is a terminal for connecting to an external power source.

(card case)
FIG. 8 shows the configuration of the card case 1 in a state in which the non-contact type card 70 is accommodated. 8A shows the configuration of the front side of the card case 1, FIG. 8B shows the configuration of the back side of the card case 1, and FIG. 8C shows the cross section of the card case 1 (in FIG. 8A). The structure of an SS line | wire cross section is shown. The card case 1 is further provided with a battery 80 and a switch button 52a as compared with the first embodiment.

  The battery 80 is an external power supply that supplies power for operating the IC chip 30 and the display device 40 of the display card 60. As can be seen from FIG. It is housed in a space formed at the right end. As the battery 80, for example, a button-type battery can be used. Moreover, as long as it can be accommodated in the card case 1, a large-sized and long-life thing may be used. The battery 80 is connected to the external terminal 58 of the display card 60 accommodated in the card case 1 through wiring.

  The switch button 52 a is a member that is provided in the vicinity of the lower right end portion of the card case 1 and operates the switch 52 of the display card 60. In this embodiment, unlike the third embodiment, the switch 52 is connected even when the switch button is not operated. When the card case 1 is used over an external device such as a ticket gate, it can be used in the same manner as in the first embodiment with the switch 52 disconnected. Further, there is no problem even if the switch 52 is used in a connected state. When the card case 1 is used without being held over an external device, power is supplied from the battery 80 to the IC chip 30 and the display device 40 via the electromotive coil 20 by connecting the switch 52, and the display device 40, information can be displayed and updated. Thereby, the balance of the charge amount of a card, etc. can always be displayed.

  When the contactless card 70 is held over an external device (for example, a ticket gate), a current flows through the electromotive coil 20. Using the current as an interrupt signal, the reading function of the IC chip 30 is activated. The reading function reads information from the non-contact type card 70 with the power supplied from the battery 80.

Each time the reading function of the IC chip 30 is activated, information read from the non-contact card 70 (recording of getting on / off the train, balance of charge amount, etc.) is recorded on the IC chip 30. The IC chip 30 has a storage capacity larger than the storage capacity of the non-contact type card 70, and can hold information for many readings (for example, 1000 times). Although the storage capacity and the amount of information to be held may be determined as design matters, in this embodiment, it is assumed that 1000 times of information can be stored. Since the information to be read is fixed and the data size of one reading is constant, the capacity required to store 1000 times of information can be determined in advance.

  If the remaining capacity of the storage capacity is insufficient to store the read information, the IC chip 30 manages the information in a FIFO format that deletes the first read information. As a result, the latest history is held. The retained information (history) can be referred to from an external device via an external connection terminal (not shown) such as a USB. The history may be displayed by operating a button provided on the display card 60.

  The non-contact type card 78 does not hold information of many times. The history can be managed by holding the information on the display card 60 many times. The held information may be transmitted to the outside via, for example, a micro USB terminal (not shown).

  The above-described display by the display device 40, which is a liquid crystal display, storage of the history in the IC chip 30, and transmission of stored information to the outside are stably performed by the power supplied from the battery 80.

  Note that an opening / closing lid may be provided on the card case 1 so that the battery 80 can be taken out and replaced. Further, the display card of the third embodiment may be accommodated in the card case 1 of the present embodiment, and the battery 80 may be connected to the power source 50 via the charging terminal 56 and charged.

  A display card that can display information recorded on a contactless card and a card case that accommodates a contactless card and can display information recorded on it. It is done.
