Patent Document 3: Japanese Patent Application Laid-Open No. 2004-280193

Disclosure of the invention

Problems to be solved by the invention

[0004] Incidentally, in recent years, fraudulent behavior called skimming has become a problem. Skimming is the act of reading account information and personal identification numbers from other people's cards, withdrawing deposits and purchasing goods.

At the time of this application, the number of cleared skimming criminals is not clear. However, it is said that non-contact type cards with embedded IC chips cannot be skimmed due to congestion during commuting! In other words, a non-contact card has a coil and an IC chip embedded in a resin card, and by applying a magnetic field to the coil, an induced current can be generated to read the IC chip data. Therefore, it has a predetermined function. You can read the account information and password recorded on the IC chip simply by bringing the card reader closer.

[0005] Therefore, when the person is in close proximity to another person, such as in a crowded train, if the person in close proximity holds the card reader, the card account number or the like may be stolen. In recent years, the performance of card readers has improved, and card readers of the same size as cards have been sold. Under such circumstances, measures to prevent skimming, which is highly anxious about skimming, are desired.

There is also a similar danger for mobile phones equipped with the above-mentioned contactless IC card function. In particular, non-contact type IC cards installed in mobile phones often use active types that operate using the battery of the mobile phone as a power source, and the communication distance is long. For this reason, there is concern that important information can be read.

[0006] Therefore, an object of the present invention is to improve a mobile terminal device such as a mobile phone and provide a mobile terminal device in which information that is difficult to be skimmed is not stolen.

Means for solving the problem

[0007] Then, an invention for solving the above-described problem is a mobile terminal device having a non-contact type IC card function, and moves in the direction of approaching and moving away from an antenna unit that exhibits the non-contact type IC card function. A portable terminal device comprising a barrier member.

[0008] Further, the invention that exhibits the same function is a mobile terminal device having a non-contact type IC card function, and moves in a direction away from the card function display unit that performs the non-contact type IC card function. A portable terminal device comprising a barrier member.

The card function exhibiting unit is an IC chip or an antenna.

The portable terminal device of the present invention includes a barrier member that moves in the direction of approaching and separating from the antenna unit and the like. Therefore, information cannot be read if the barrier member is placed close to the antenna portion or the like during carrying. When paying with a card or withdrawing a deposit, the barrier member is separated from the antenna portion. As a result, electromagnetic waves and magnetic lines can be emitted from the antenna unit, and communication with the card reader becomes possible.

[0010] The barrier member described above attenuates, for example, electromagnetic waves or lines of magnetic force.

That is, non-contact type IC cards are known to be based on an electromagnetic coupling method and a microwave method. Yes. Here, the former electromagnetic coupling method communicates using mutual induction of coils by an alternating magnetic field. Therefore, in a portable terminal device that employs an electromagnetic coupling method, a barrier member that shields or attenuates a magnetic field is employed.

In the portable terminal device that employs the latter microwave method, a barrier member that shields or attenuates electromagnetic waves is employed.

[0012] The barrier member is preferably a plate having a metal layer.

[0013] The metal layer has a function of attenuating electromagnetic waves and magnetic fields. It also has the function of reducing the antenna efficiency by interfering with the antenna. Therefore, a plate with a metal layer is recommended as a barrier member. The “plate body having a metal layer” includes, for example, a plate in which a metal layer is coated on a resin plate or the metal plate itself.

That is, the barrier member may be a plate having a metal layer and a resin layer.

[0015] Although the attachment position of the barrier member is arbitrary, when the mobile terminal device includes a battery mounting portion for mounting the battery and a lid body for covering the battery mounting portion, the barrier member is the lid body. It is recommended to be attached to.

[0016] In the mobile terminal device of the present invention, since the barrier member is attached to the lid that covers the battery mounting portion, the barrier member is also detached when the lid is removed. Therefore, the barrier material does not get in the way when replacing the battery.

[0017] Preferably, the barrier member slides along the surface of the casing of the mobile terminal device.

[0018] In the mobile terminal device of the present invention, since the barrier member slides along the surface of the housing of the mobile terminal device, the thickness of the housing is not so thick.

[0019] The barrier member is preferably inserted into the bag portion, and a part of the barrier member enters and exits from the bag portion.

[0020] In the mobile terminal device of the present invention, the barrier member is inserted into the bag portion, and a part of the barrier member enters and exits from the bag portion, so that the appearance is good.

[0021] Preferably, the barrier member is provided with a knob.

[0022] In the portable terminal device of the present invention, since the barrier member can be moved by operating the knob, operability is good. [0023] Still another invention of the mobile terminal device is a card that exhibits a non-contact type IC card function in a mobile terminal device that has a non-contact type IC card function with an electronic component built in the housing. A portable terminal device characterized in that a removable barrier member is provided on a housing surface facing a function exhibiting section.

[0024] In the mobile terminal device of the present invention, a removable barrier member is provided on a housing surface facing a card function exhibiting section such as an antenna section. For this reason, if a barrier member is attached at the time of carrying, information cannot be read out. Also, when paying with a card or withdrawing a deposit, the barrier member is removed from the housing surface. As a result, electromagnetic waves and lines of magnetic force can be emitted from the antenna unit and the like, and communication with the card reader becomes possible.

[0025] The barrier member attenuates electromagnetic waves or lines of magnetic force.

The barrier member is a plate or sheet having a metal layer, and preferably has a glue layer on one side and is attached to the housing surface by the glue layer.

[0026] Still another invention is a skimming prevention device attached to a portable terminal device having a non-contact type IC card function, and is provided in a card function exhibiting unit such as an antenna unit that exhibits the non-contact type IC card function. On the other hand, the skimming prevention device is characterized by including a barrier member that moves in the approaching / separating direction.

[0027] Yet another invention is a skimming prevention device attached to a portable terminal device having a non-contact IC card function, which is a plate or sheet having a metal layer, and has a glue layer on one side. The skimming prevention device is characterized in that it can be attached to the housing surface by the adhesive layer.

[0028] In the portable terminal device to which the skimming prevention device of the present invention is attached, the risk of skimming is reduced.

The invention's effect

[0029] The mobile terminal device of the present invention has the effect of being able to attenuate electromagnetic waves and the like that are also generated by the antenna portion of the IC card function by the barrier member, and to prevent theft of information due to skimming.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will be further described below. The mobile phone (mobile terminal device) 1 of the present embodiment includes a non-contact IC card function (RFID function: Radio Frequency Identification function) in addition to a normal call function! The mobile phone 1 has a skimming prevention device 2 attached to the back side.

[0032] The mobile phone 1 has a folding structure in which the body is folded in two. That is, the mobile phone 1 has two case portions 5 and 6, and both are connected by the hinge 7.

The mobile phone 1 opens the case parts 5 and 6 when the mobile phone 1 is used, as shown in the figure when the two case parts 5 and 6 are folded. In the same manner as known, an operation surface is provided on the inner surface of the case portions 5 and 6 (not shown).

Further, as shown in FIG. 2, a skimming prevention device 2 is attached to the back side of the mobile phone 1. The skimming prevention device 2 is composed of a bag-like member 10 and a metal plate (barrier member) 11 as shown in FIG. The bag-shaped member 10 has a substantially square overall shape and is made of a thin resin sheet or a resin sheet. In the present embodiment, the bag-like member 10 is made of a thin resin sheet and has considerable rigidity. The bag-like member 10 has a surface member 15 and a back member 16 as shown in FIG. The front member 15 and the back member 16 are bonded to each other on three sides, and the intermediate portion is in a non-bonded state. Therefore, one side is open and the inside is in a bag state.

The surface member 15 is provided with a rectangular opening 17.

[0034] Specifically, the metal plate 11 is an aluminum plate. A knob 18 is provided on one surface of the metal plate 11.

The shape of the metal plate 11 is substantially square, and is substantially equal to the internal shape of the bag-like member 10 described above. The metal plate 11 is inserted into the bag-like member 10, and the knob 18 is exposed from the opening 17 provided in the surface member 15 of the bag-like member 10.

When the knob 18 is operated, the metal plate 11 slides. That is, as described above, since the shape of the metal plate 11 is substantially square and substantially the same as the internal shape of the bag-like member 10, the movement of the metal plate 11 is linearly restricted. Therefore, when the knob 18 is operated, the metal plate 11 slides linearly, and a part of the metal plate 11 appears and disappears from the opening 20 on one side of the bag-like member 10.

In the mobile phone 1 of the present embodiment, the skimming prevention device 2 is attached to the lid (lid body) 23 of the battery mounting portion 22 with an adhesive, not shown! / That is, the mobile phone 1 is provided with a battery mounting portion 22 for storing a battery, similar to a known one, and a lid (cover) 23 for covering the battery mounting portion 22 is provided on the back side of the mobile phone 1. In the mobile phone 1 of the present embodiment, the back member 16 of the bag-like member 10 of the skimming prevention device 2 is bonded to the lid (lid body) 23 described above.

[0036] As described above, the mobile phone 1 of the present embodiment has a non-contact type IC card function. The main components for realizing the contactless IC card function are an IC chip (card function display unit) 30 and an antenna (RFID antenna) 31.

In the present embodiment, the IC chip 30 is in the casing 35 of the mobile phone 1, and a part thereof is exposed to the battery mounting portion 22 as shown in FIG.

The antenna 31 is built in the casing 35 of the mobile phone 1 and is near the back surface of the casing 35.

Next, a method for using the mobile phone 1 of the present embodiment will be described.

When carrying the mobile phone 1 of the present embodiment, the metal plate 11 of the skimming prevention device 2 is exposed from the bag-like member 10 as shown in FIG. Board

Cover the outside of the antenna 31 with 11.

More specifically, the knob 18 is operated to move the knob 18 to the opening 20 side of the bag-like member 10. As a result, the metal plate 11 slides linearly along the surface of the housing 35, and a part of the metal plate 11 is exposed from the opening 20 of the bag-like member 10. The exposed part is close to the antenna 31 and finally covers the antenna 31.

As a result, electromagnetic waves and magnetic lines of force emitted from the antenna 31 are attenuated, and information recorded on the IC chip 30 cannot be read even if the card reader is brought closer.

Therefore, you will not be skimmed by others!

[0039] Further, when performing the withdrawal of the deposit by demonstrating the card function, the knob 18 is operated in the reverse direction to pull the metal plate 11 into the bag-like member 10. As a result, the metal plate 11 is separated from the antenna 31 and can transmit electromagnetic waves or the like from the antenna 31, and can communicate with the card reader to withdraw or borrow money.

In the embodiment described above, the skimming prevention device 2 is attached to the lid (lid body) 23 of the battery mounting portion 22. This configuration prevents the skimming prevention device 2 from getting in the way when replacing the battery. Although it is a recommended configuration, it is possible to attach the skimming prevention device 2 to the main body.

[0041] In the embodiment described above, when carrying the mobile phone 1, the metal plate 11 of the skimming prevention device 2 is exposed from the bag-like member 10 as shown in FIG. The force with which the metal plate 11 can be drawn into the bag-like member 10 when pulling out or the like may be reversed.

That is, like the mobile phone 36 shown in FIGS. 6 and 7, the skimming prevention device 2 is provided in a portion corresponding to the IC chip 30 and the antenna 31, and when the mobile phone 36 is carried, as shown in FIG. While the metal plate 11 of the skimming prevention device 2 is drawn into the bag-like member 10, the metal plate 11 is taken out from the bag-like member 10 when the card function is performed and the deposit is withdrawn.

The components of the mobile phone 36 shown in FIGS. 6 and 7 are the same as those of the mobile phone 1 shown in FIG. 1 and the like, and thus the same members are assigned the same reference numerals and detailed description thereof is omitted.

In the embodiment described above, the skimming prevention device 2 is attached to the lid (lid body) 23 of the battery mounting portion 22. This configuration is a recommended configuration so that the skimming prevention device 2 does not get in the way when the battery is replaced, but the skimming prevention device 2 can also be attached to the main body.

Further, in the above-described embodiment, the force by which the metal plate 11 is linearly moved to approach and separate from the antenna 31 is not limited to this configuration. For example, as shown in FIG. The metal plate 45 can be rotated to move closer to or away from the antenna 31.

That is, FIG. 8 is a perspective view showing a main part of a mobile phone adopting the skimming preventing device of still another embodiment of the present invention.

In the mobile phone (mobile terminal device) 43 shown in FIG. 8, the skimming prevention device 38 includes a disk-shaped metal plate (barrier member) 45 that is partially cut away. The metal plate 45 can be rotated by operating the center knob 46. Communication with an external card reader becomes possible by matching notch 47 with an antenna not shown. Moreover, skimming can be prevented by covering the antenna portion with a plate-like portion.

In the above-described embodiment, the force that moves the metal plate 11 to shield the antenna 31 attaches the metal plate 11 to the housing surface facing the antenna 31 of the housing 35 to shield the antenna 31 and force The metal plate 11 may be removed when the deposit function is performed by performing the card function.

As a mounting structure of the metal plate 11, a configuration in which an engagement portion with the metal plate 11 or a clasp is provided in the casing 35 can be considered. Then, the metal plate 11 is attached to a predetermined position of the housing 35 by a method such as locking the engaging portion to the metal plate 11.

On the other hand, when pulling out the deposit, etc., the engagement portion is disengaged and the metal plate 11 is removed.

Furthermore, as a simpler structure, the metal plate 11 may be attached to the casing surface of the casing 35 facing the antenna 31 like a mobile phone (mobile terminal device) 50 shown in FIG. In the embodiment shown in FIG. 9, a paste layer (not shown) is provided on the metal plate 11, and the metal plate 11 is attached via the paste layer.

The adhesive layer has low adhesiveness, and the metal plate 11 can be easily peeled by hand.

When performing the withdrawal of a deposit by demonstrating the card function, the metal plate 11 is peeled off and removed to expose the surface of the housing 35.

The adhesive layer is preferably one that can withstand reuse, but it may not withstand reuse.

In this case, since the shielding member is disposable, it is desirable to use a cheaper material. For example, it is conceivable to use a shielding film including a metal layer instead of a metal plate.

In the embodiment described above, the metal plate is used as the barrier member. However, instead of the metal plate, a resin plate on which a metal film is laminated may be used.

FIGS. 10 to 16 show modified examples of the barrier member, and are sectional views of the barrier member in which a metal layer and a resin layer are laminated. The metal layer is made of a metal such as aluminum, copper, silver, or iron. The barrier member shown in FIGS. 11 to 16 is further provided with a carbon layer.

[0048] It is also possible to prepare for skimming by attaching the skimming prevention device described above to an existing mobile phone.
