Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable telephone with a contactless IC card function.

[0002]

2. Description of the Related Art When a card such as a ticket or a commuter pass is inserted, an automatic ticket gate such as a subway reads data recorded on the card. The automatic ticket gate main body performs an arithmetic process based on the read data, and an entrance / exit process is performed based on the arithmetic process. Recently, a system for performing entry / exit processing using a non-contact IC card having a communication function has been proposed and put into practical use.

[0003] When a non-contact IC card is used as a general-purpose ticket, the card is carried as a ticket, a commuter pass or the like, which is not so different from the conventional one. Therefore, by using a mobile phone that is widely used, the mobile phone itself has a function that can be used as a mobile phone and a function that can be used as a non-contact IC card, so that the non-contact IC card can be carried separately. The idea of realizing a comfortable and smooth ticket gate is found in Utility Model Registration No. 3064207.

FIG. 2 is an image view of a conventional portable telephone. 7a is a mobile phone main body, 8 is a mobile phone antenna, 9
Denotes a liquid crystal display unit.

FIG. 3 is an image diagram of a portable telephone with a non-contact IC card function when a conducting wire antenna 10 is used as an antenna for the non-contact IC card. The conducting wire antenna 10 is constituted by a conducting wire wound in a coil shape. The conducting wire antenna 10 is arranged around a structure functioning as a mobile phone. 7b is the size when only the mobile phone function is provided, and is the same size as the mobile phone body 7a in FIG. The mobile phone with a non-contact IC card function of FIG. 3 is larger than that of FIG.

FIG. 4 is an image diagram when a pattern antenna 11 is used as an antenna for a non-contact IC card in a mobile phone with a non-contact IC card function. The pattern antenna 11 is formed by forming a coil-shaped pattern on a substrate on a plurality of surfaces of the substrate. The pattern antenna 11 is arranged outside a structure functioning as a mobile phone. The mobile phone with a contactless IC card function of FIG. 4 is larger than that of FIG.

When the user confirms the information stored in the non-contact IC card, for example, a lift coupon at a ski resort is displayed on a display of a non-contact IC card reading terminal provided at the lift boarding gate. Information is confirmed by displaying the remaining number of times and the like. In a station ticket gate system and the like, a terminal installed at a station or the like is used, and a remaining charge or the like is confirmed on a display unit of the terminal.

[0008]

The components for functioning as a non-contact IC card are an electronic component including an IC chip, a board on which the electronic component is mounted, and an antenna. Although the electronic components have a small volume and little effect on the size, the antenna is large in size.

FIGS. 3 and 4 show that the size of the antenna is larger than that of FIG. 2 and the main body is larger. As mobile phones become smaller and smaller, the larger the main unit becomes less attractive as a product.

[0010] Since a plurality of antennas are mounted, the structure becomes complicated and the cost increases.

When the information of the non-contact IC card function is confirmed, a terminal installed at a station or the like must be used in a station ticket gate system, which is inconvenient.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a portable telephone with a non-contact IC card function that is more convenient without increasing the size of the main body.

[0013]

In a portable telephone with a contactless IC card function having a portable telephone function and a contactless IC card function, at least the antenna part and the display part are provided with the portable telephone function part and the noncontact IC card function part. And a mobile phone with a non-contact IC card function that shares one of the switch operation unit.

The mobile phone function section and the non-contact IC card function section are mobile phones with a non-contact IC card function in which an antenna section, a display section and a switch section are shared via a control section.

[0015]

FIG. 1 is a block diagram showing an embodiment of the present invention. 1 is a mobile phone function unit, 2 is a non-contact I
A C card function unit, 3 is a control unit, 4 is an antenna unit, 5 is a display unit, and 6 is a switch operation unit.

When the antenna unit 4 receives a radio wave, the control unit 3
The signal is transmitted to The control unit 3 processes the signal, and if the received radio wave is a radio wave for a mobile phone, transmits the signal to the mobile phone function unit 1. The signal is processed by the mobile phone function unit 1, and thereafter, the mobile phone function unit 1, the antenna unit 4, the display unit 5, and the switch operation unit 6 each operate via the control unit 3 in the same manner as a conventional mobile phone, Existing services such as telephone calls and Internet connection can be received.

If the received signal is a radio wave for a non-contact IC card, the signal is transmitted to the non-contact IC card function unit 2. The signal is processed by the non-contact IC card function unit 2, and thereafter, the non-contact IC card function and the antenna unit 4 operate in the same manner as the conventional non-contact IC card via the control unit 3, respectively. If it is a radio wave used in an automatic ticket gate such as a subway, communication and processing are performed, and it is possible to pass through a ticket gate. In this case, since the conventional non-contact IC card is merely replaced by a mobile phone with a non-contact IC card function, other systems and devices, such as an automatic ticket gate, are the same as the conventional one.

When the user performs a switch operation, a signal is transmitted to the control unit 3. The control unit 3 processes the signal according to the state of the mobile phone with the non-contact IC card function and the contents of the operated switch, and transmits the signal to the mobile phone function unit 1 if the content is for a mobile phone. The signal is processed by the mobile phone function unit 1, and thereafter, the mobile phone function unit 1, the antenna unit 4, the display unit 5, and the switch operation unit 6 each operate via the control unit 3 in the same manner as a conventional mobile phone, Existing services such as telephone calls and Internet connection can be received.

If the switch operation is the content of information confirmation in the non-contact IC card function, the control unit 3
Necessary information is extracted from the card function unit 2, and a non-contact IC
The information drawn from the card function unit 2 is displayed on the display unit 5. For example, if the information that the user wants to know in the non-contact IC card function unit 2 is the balance information, the information is displayed as shown in FIG.

In the above-described embodiment, the antenna unit 4, the display unit 5, and the switch operation unit 6 are shared, but any one of the antenna unit 4, the display unit 5, and the switch unit 6 is used. One or two may be shared.

[0021]

As described above, in a portable device having a portable telephone function and a non-contact IC card function, a single antenna can be used by sharing an antenna unit, thereby preventing an increase in the size of the main body.

By having one antenna, the structure can be simplified,
Cost can be reduced.

By using the display unit and the switch operation unit, not only the information as a mobile phone but also the information as a non-contact IC card can be displayed.
