Description

The present invention, non-contact terminal device (e.g., card reader) relates IC card that communicates with a non-contact state between the relates to IC cards has been particularly with multiple IC chips.

  In recent years, mobile phones or IC cards in which IC chips for recording and computing various information are embedded are remarkably widespread, and various services using these media are provided by various service organizations (for example, transportation facilities, convenience stores). Has been deployed.

  Specifically, IC chips are widely used in systems in various fields such as finance, point management, entrance / exit management, personal information management, etc., and mobile phones or IC cards equipped with IC chips are contactless, A predetermined service (electronic payment, personal authentication, etc.) is provided by communicating with a non-contact type terminal device (for example, a card reader device) installed by various service organizations. Above all, the contactless authentication system using this system has been steadily penetrating into our daily life, mainly in the security system of condominiums.

  Under such circumstances, development of media corresponding to a plurality of services that can be provided by each contactless terminal device and improvement in usability of the media have been demanded. For example, in order to construct an environment that supports a plurality of services in a mobile phone, it can be easily realized by downloading and installing a predetermined application in the internal memory of the mobile phone.

  On the other hand, in the case of an IC card, a mechanism in which one service can be used with a single card is generally used. Therefore, when a user wants to use a plurality of services, the user needs to carry a plurality of cards. There was lack of convenience.

  In addition, a non-contact type IC card that can support a plurality of services with a single card has been proposed (see Patent Document 1), but it is necessary to incorporate a plurality of control circuits to reliably link communication. There is a problem that the control of the IC chip is complicated. In addition, since a host device having a plurality of reading functions is used, there is a problem that the dependence on the reading-side device is high and environmental constraints are often imposed (see Patent Document 2).

In view of the above situation, we have the information to perform multiple media functions, to provide an IC card which can be user side utilizing reliably and easily identify service Objective.

In order to achieve the above object, the first aspect of the present invention provides:
Three IC chips are mounted, and when performing predetermined communication with each IC chip in a non-contact state, the two IC chips do not interfere with electromagnetic waves transmitted by the remaining one IC chip. An IC card having two shielding plates for switching a communicable area enabling communication with a specific IC chip to shield other areas than the communicable area,
The two shielding plates are formed so as to be movable in the X-axis direction from a specific IC chip toward an adjacent IC chip,
One end of the wire is fixed to one shield plate, while the other end of the wire extending in the X-axis direction is suspended on the other shield plate, and the extending direction of the wire is orthogonal to the X-axis. A pulley member that changes in the Y-axis direction is attached rotatably.
Further, a connecting lever fixed to the other end of the wire and formed to be movable along the first guide means in the Y-axis direction, and the X-axis from the other shielding plate toward the one shielding plate. A fixed latch comprising a release lever that is formed to be movable in the X-axis direction along the second guide means, the position of which is regulated by the second guide means formed in the direction;
One shielding plate shields the IC chip on one end side, and the other shielding plate shields the IC chip on the other end side, so that the compressive force does not act at the initial position where the communicable area of the central IC chip is formed. An elastic material configured so that one end abuts one shield plate and the other end abuts the other shield plate;
When moving one of the shielding plates from the initial position , the connecting lever is moved downward along the first guide means to resist the spring force of the elastic material through the wire. Then, the one shielding plate is moved to a position where it abuts against the other shielding plate, the connecting lever is engaged with the release lever at this position, and the both are integrated as a fixed latch, thereby providing an IC chip on one end side. And the one shielding plate is moved to the initial position by the spring force of the elastic material acting via the wire by releasing the engaged state with the connecting lever by operating the release lever. While returning to
The one shielding plate and the other shielding plate are integrally moved by moving the release lever of the integrated fixed latch along the second guide means in one direction along the X-axis direction. While moving to the one end side to form a communicable area of the IC chip on the other end side,
The release lever of the integrated fixed latch is moved in the opposite direction along the X-axis direction along the second guide means from the state where the communicable area of the IC chip on the other end side is formed. The one shielding plate and the other shielding plate are integrally moved to the other end side to return to the original position so that a communicable area of the IC chip on one end side is formed. It is in the IC card.

In this aspect, by switching the communicable area by the shielding means, it is possible to reliably use only a specific service even if it has a plurality of functions. In addition, by shielding any two of the three IC chips and shielding them, only the IC chip to be used can be made effective.

Based on the information, it is assumed that different services such as electronic money, management of membership-based shared facilities, and home security are provided.

  As shown in the figure, the IC card 10A of the present embodiment is formed so that the internal space is divided into three parts with the partition shielding plates 11a and 11b therebetween, and the IC chips 12a, 12b, and 12c (hereinafter collectively referred to as “internal space”). An “IC chip 12”) and antennas 13a, 13b, and 13c (hereinafter collectively referred to as “antenna 13”) are mounted on each. As a shielding means for shielding electromagnetic waves in a specific area in the IC card 10A, the shielding plates 14a and 14b and the sliding mechanism 150 that slides the shielding plates 14a and 14b in the longitudinal direction are provided (details will be described later). . In addition, end shielding plates 16 are provided at both ends of the IC card 10A.

  The shielding plates 14a and 14b (hereinafter collectively referred to as “shielding plate 14”) are provided above and below the substrate on which any one of the IC chip 12 and the antenna 13 is mounted. By this operation, the other IC chip 12 and the antenna 13 are simultaneously moved up and down to move to the substrate side. The shielding plate 14 may be mounted on the interior or the exterior as long as the electromagnetic wave can be reliably shielded. In the case of the exterior, a structure in which the shielding plate 14 is directly moved manually may be used.

  Here, the slide mechanism 150 will be specifically described. FIG. 3 is a schematic view showing a slide mechanism of the IC card according to the second embodiment, and FIG. 4 is a side view showing a fixing latch constituting a part of the slide mechanism of the IC card according to the second embodiment.

  As shown in the figure, the sliding mechanism 150 is mounted on the shielding plate 14b that connects or moves the shielding plates 14a and 14b, and the pulley member 18 that is mounted on the shielding plate 14b and operates one of the fixing latches 17 (described later, a coupling lever 17A). The elastic body material 19 is configured to draw and connect the shielding plate 14a to the shielding plate 14b side by operating the connecting lever 17A.

  The fixed latch 17 includes a connecting lever 17A that moves in the direction of the flow line 1 and a release lever 17B that moves in the direction of the flow line 2 on the surface on the shielding plate 14b side. A slide movement groove 21a for operating the connecting lever 17A in the direction of the flow line 1 is provided at the base end in the width direction, and a slide movement groove 21b for operating the release lever 17B in the direction of the flow line 2 is long. It is provided at the base end of the direction.

  Here, the contact surfaces of the connecting lever 17A and the release lever 17B are configured to fit together when connected (see FIG. 4). The fixed latch 17 is configured such that the connecting lever 17A is released to a fixed position in the direction of flow line 1 when the release lever 17B is pressed.

  The elastic material 19 has one end provided on the shielding plate 14a and the other end on the shielding plate 14b via the wire 20 from the connecting lever 17A. Examples of such an elastic material 19 include a spring and a bellows. The shielding plates 14a and 14b are preferably provided with a space for storing the elastic material 19 that shrinks when the shielding plates 14a and 14b are connected.

  With the configuration as described above, the internal space of the IC card 10A is divided into three parts, and communication is possible to enable communication with only one of the IC chips 12 so that the other does not interfere with one electromagnetic wave. A region is formed. That is, when a specific space (a portion surrounded by a thick line shown in FIG. 2) is sealed by the partition shielding plate 11, the shielding plate 14, and the end shielding plate 16, electromagnetic waves emitted from the space are blocked. Thus, only communication based on electromagnetic waves emitted from a space that is not in a sealed state (other than a portion surrounded by a thick line shown in FIG. 2) is effective.

  Further, by operating the slide mechanism 150 to switch the shielding plates 14a and 14b to predetermined positions, the shielding plates 14a and 14b are moved to any one region, and the communicable region can be freely switched. In the example shown in FIG. 2, a central area that is not shielded (not covered) by the shielding plates 14a and 14b forms a communicable region. Moreover, the material etc. will not be specifically limited if the partition shielding board 11, the shielding board 14, and the edge part shielding board 16 can interrupt | block electromagnetic waves reliably.

  Here, a method of switching the communicable area by the shielding plates 14a and 14b will be described. FIG. 5 is a diagram for explaining an IC card switching operation according to the second embodiment.

  As shown in the figure, the IC card 10A of the present embodiment is divided into three areas on which the above-described IC chip 12 and antenna 13 are mounted, and any two areas are shielded by the shielding plates 14a and 14b. (A hatched portion shown in the figure), only one specific area other than the area forms a communicable region.

  Here, in the example shown in FIG. 5A, the central area of the IC card 10A is a communicable area. This state is a state where the slide mechanism 150 is not operated.

  In the example shown in FIG. 5B, the area on the left side of the IC card 10A is a communicable area. In this case, by operating the connecting lever 17A in the direction of the flow line 1, the shielding plate 14a moves to the shielding plate 14b side, and the shielding plate 14a and the shielding plate 14b are connected to each other. By such an operation, the communicable area of the IC card 10A can be switched from the state shown in FIG. 5A to the state shown in FIG.

  In the example shown in FIG. 5C, the area on the right side of the IC card 10A is a communicable area. In this case, by operating the release lever 17B in the direction on the flow line 2, the shielding plate 14b moves to the left side of the IC card 10A alone or in a state connected to the shielding plate 14a. By such an operation, the communicable area of the IC card 10A can be switched from the state shown in FIG. 5A or the state shown in FIG. 5B to the state shown in FIG.

  In the IC card 10A of the present embodiment, only the electromagnetic wave emitted from the communicable area formed as described above is enabled, and the IC chip 12 and the non-contact type terminal device (card reader device, etc.) that are enabled By performing predetermined communication in a non-contact state with the user, the user can easily use the specific service provided by the specific IC chip 12 easily.

(Embodiment 3)
FIG. 6 is a schematic diagram of an IC card according to the third embodiment, and FIG. 7 is a diagram illustrating a method for using the IC card according to the third embodiment. In the present embodiment, a case where two IC chips that execute different services are mounted on the IC card 10B will be described.

  6A is a front view of the IC card 10B, FIG. 6B is a back view of the IC card 10B, and FIG. 6C is a side view of the IC card 10B. The same IC chip 12 and antenna 13 as those in the first and second embodiments are mounted (not shown).

  As shown in the figure, the IC card 10B of the present embodiment is divided into two areas on which the IC chip 12 and the antenna 13 described above are mounted, respectively, on one half surface of the back surface of the IC card 10B. As described above, an electromagnetic shielding material is applied as shielding means, and shield members 22a and 22b for shielding electromagnetic waves are formed. That is, the electromagnetic shielding material is applied to the left area on the front surface and the right area on the back surface.

  Further, a movable member 23 is provided at the center of the IC card 10B so that either one of the shield members 22a and 22b forms a surface layer of the card substrate. Such a movable member 23 may be of any structure that can be bent at least at the center of the card substrate. For example, a flexible elastic body or the like depending on the thickness of the IC chip 12 to be mounted. What is necessary is just to employ | adopt suitably what was connected using the laminate raw material, and the hinge structure using a rod-shaped core material. Similarly, by forming the movable member 23 from an electromagnetic wave shielding material, it is possible to shield electromagnetic waves emitted from either one of the surfaces in a superposed state. In this case, it is preferable to provide the boss holes 24 in four directions so that the front surfaces or back surfaces of the IC card 10B are securely fixed and fitted at predetermined positions.

  With the above-described configuration, the state illustrated in FIG. 7 can be formed by bending the IC card 10B with respect to any surface and overlapping each outer side to form a shield. In the example shown in FIG. 7, the front surface is shielded by folding the IC card 10B so that the shield member 22a is in the outward state and the shield member 22b is in the inward state, and electromagnetic waves emitted from the back surface are effective. Become. On the other hand, by folding the IC card 10B in a valley, the electromagnetic wave emitted from the front surface becomes effective and the back surface can be shielded. In this way, by using the shield members 22a and 22b and the movable member 23 as shielding means, the region where the electromagnetic waves of the IC chip 12 other than the specific IC chip 12 are effectively operated is shielded. Can do.

  Each of the above-described embodiments is a preferred embodiment of the present invention, and various modifications can be made without departing from the gist of the present invention.

  For example, in Embodiment 3 described above, the shield members 22a and 22b are formed by applying an electromagnetic wave shielding material. However, the present invention is not particularly limited to this. For example, a metal or a seal formed of an electromagnetic wave shielding material is used. You may make it stick.

  In the third embodiment described above, the boss holes 24 are provided in four directions. However, the present invention is not limited to this, and the IC card 10C may be provided with fitting grooves 25 as illustrated in FIG. Furthermore, the sealed state may be formed by magnetic force instead of the boss hole 24 and the fitting groove 25. In this case, it is necessary to form the outer side (outer edge) constituting each surface of each area with a magnetic material so that at least electromagnetic waves are not affected by the magnetic force (so as not to malfunction).
