Description

  The present invention relates to a mobile phone terminal having a non-contact type IC card function.

  In recent years, various commercializations are planned in various industries for the purpose of full-scale spread of IC cards. For example, the next telephone card planned by NTT and the electronic ticket (IC commuter pass) scheduled by JR East. These IC cards are non-contact type IC cards in terms of reliability and application.

  Non-contact type IC cards are classified into “contact type”, “proximity type”, and “neighboring type” according to communication distance and method (usage frequency, etc.), and the international standards ISO / IEC10536, ISO / Standardization is underway as IEC14443 and ISO / IEC15693. For example, the maximum communication distance with the “contact type” reader device is about 2 mm. Similarly, the “proximity type” is about 10 cm and the “neighbor type” is about 70 cm.

  In general, a non-contact type IC card has a business card size and does not have a power source. Therefore, power for operating the IC card is supplied by electromagnetic waves from the reader / writer device.

In general, when information is input to and output from an IC card, it is performed via a reader / writer device.
JP-A-11-213111 JP2003-060748 JP2002-222442

  As described above, normally, an IC card is not provided with a power source, and power for operating the IC is supplied by electromagnetic waves from a reader / writer device, and the power is stipulated by the Radio Law. Then, there is a drawback that the communication distance is shortened.

  Further, since the IC card does not have a display function, when viewing information data recorded on the IC card, there is a disadvantage that the reader / writer device must be separately provided.

  Furthermore, when information on an electronic wallet or electronic commuter pass is held, it is necessary to perform information via a reader / writer device each time information data such as deposit is input, which is inconvenient.

  Accordingly, a first object of the present invention is to provide an IC card and a communication terminal having an IC card function that can easily input necessary information and confirm or authenticate the information. A second object is to provide an IC card that can extend the communication distance without changing the shape and the like, and a communication terminal having an IC card function.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  In order to solve the above problems, the invention of claim 1 is a communication terminal (5) having a mobile phone terminal antenna (14) for transmitting / receiving information data to / from a partner company, and an external reader / writer. A mobile phone terminal (2) comprising an IC card function unit (6a) having an IC card function unit antenna (18) for transmitting and receiving with the device (35), wherein the communication terminal (5) The CPU (13) is built in, and the CPU (13) is an I / O device (7) for inputting / outputting information data to / from the IC card function unit (6a) and an operation for operating the mobile phone terminal. Control unit (10), communication unit (11) in communication terminal (5) and display unit (12) for displaying information, and IC card function unit (6a) is connected to communication terminal (5). Power from the power source (9) of the IC card function unit 6a) includes a power supply device (20) for supplying power to the components, and the power supply device (20) includes the IC card function antenna (18) in the magnetic field region of the reader / writer device (35). The power is supplied only to each part of the IC card function part (6a).

Is provided with an IC card function section having a memory (15) as a storage means for storing information data via an I / O device (7, 8) as an input / output means. The information data received from the partner company via the communication means can be directly stored in the memory of the IC card function unit via the input / output means, and without using a reader / writer device as in the past. It is convenient because it is good, and it is technically simple and inexpensive. That is, ISO / IEC14443TYPEA or TYPEB has a different modulation method for reading and writing, and therefore, when communicating between readers / writers, it is complicated to demodulate and perform modulation corresponding to each. Therefore, it is simplified by providing the communication terminal with the IC card function. Further, the IC card function unit may be used as it is as an IC card having the function.

  According to the present invention, it is possible to check the contents (information data) stored in the IC card function unit without using a reader / writer device.

  According to the present invention, the communication terminal has a power source, and the IC card function unit is provided with the transmission / reception unit (16) as the second communication means and the power supply device (20) as the power supply means, Since power can be supplied from the power supply of the communication terminal to each part of the IC card function unit, the communication distance can be extended. Moreover, the shape of the antenna (18) of a transmission / reception part can be made small by presetting the electric power to supply and communication distance. Furthermore, in order to avoid wasted power consumption, power is supplied to each part of the IC card function unit only for the minimum necessary time (corresponding to communication time), so useless power is not used.

  According to the present invention, a transmission / reception unit as a communication unit for transmitting / receiving information, a memory as a storage unit for storing received information, and an input / output unit capable of inputting / outputting information to / from another terminal I / O device (8) as a display unit, a display unit as a display unit for displaying information data, an operation unit as an operation unit for performing an operation for designating information to be displayed, and a CPU including an integrated circuit And a power supply circuit (21) having an antenna (21a) as receiving means for receiving power from the outside, and a power storage device (22) as power storage means for storing power The power supplied from the outside (for example, the reader / writer device) is stored in the power storage means via the receiving means, and the power is directly supplied to the IC card or the communication terminal. It is possible to extend the release. In addition, since power is supplied only when the receiving unit of the IC card function unit or the communication terminal exists in the magnetic field region of the reader / writer device, useless power is not used. Further, by setting the power supplied to the IC card function unit and the communication distance, the shape of the antenna included in the power supply circuit can be reduced.

  According to the present invention, electric power for operating the IC card function unit can be generated by the solar battery, and the electric power can be stored by the storage means. In addition, the stored electric power can be supplied to each part of the IC card function part as necessary.

  In addition, when power is not supplied to each part of the IC card function part including a failure of the power storage means or the external power supply, each part of the IC card function part is operated by the power supplied from the reader / writer device. Can be read by an external reader / writer device, the stored memory contents (information data, etc.) can be read by another IC card or a communication terminal equipped with an IC card function, or moved to another terminal. Serviceability is improved.

  According to the present invention, it is possible to easily confirm the contents of information data recorded in an IC card or a memory of a communication terminal having an IC card function. Further, even if recording to the memory of the IC card function unit does not use a reader / writer, the information data can be recorded in the memory of the IC card function unit only by connecting to the mobile company and receiving the information data. Furthermore, the communication distance can be extended by supplying power for operating the IC card as an external power supply from the outside to the power supply circuit of the IC card function unit.
