Description

  The present invention relates to a mobile terminal device having a proximity communication function for non-contact communication with other devices existing at a relatively close distance, and more particularly to a user interface for user input operation.

  For example, in a mobile terminal device such as a mobile phone device or a personal digital assistant (PDA), there is a restriction that an operation unit and a display unit are generally relatively small in order to give priority to downsizing of the device. There is a problem that input operation is difficult. Therefore, for mobile terminal devices, various techniques related to user interfaces for improving operability related to user input operations have been proposed.

  For example, Patent Document 1 proposes that a user responds to a telephone when the user taps the device. Patent Document 2 proposes that the ringing sound be stopped when the user strikes the device. Patent Document 3 proposes that when a user strikes the device, a function is called according to the pattern (strength or interval). Patent Document 4 proposes switching to an off-hook state when a user strikes the device. Patent Document 5 proposes switching the response to the hold state when the user hits the device.

  In other words, since the device executes a function in response to the user's tapping operation, it is unnecessary for the user to operate a small button on the operation unit of the device, and improvement in operability can be expected. However, since the hitting operation is extremely simple, the number of functions that can be executed in response to the operation is practically limited to one, and the actual value is not necessarily high. It is. For example, when the types of patterns to be struck are differentiated into a plurality of types as in Patent Document 3, the user must remember the difference between the patterns in advance, and the operation may become troublesome.

  By the way, among the recently developed mobile terminal devices, there are devices that can perform near field communication that performs non-contact communication with other devices at a short distance. For example, by mounting a non-contact communication unit having a non-contact IC card function such as “FeliCa (registered trademark)” on the apparatus, non-contact communication is performed and the non-contact communication unit is stored in the memory. Value information having a monetary value in advance, that is, electronic money that holds a payment function and the like is becoming widespread.

  Consider a case where an input operation is performed when various functions using proximity communication are executed in such a portable terminal device. In the conventional input operation of the mobile terminal device, the user selects a desired function from a menu list displayed on the screen of the device, or operates a dedicated button provided on the device. , Input operation is to be performed. In addition, in a mobile terminal device equipped with a current non-contact communication unit, the non-contact communication unit of the mobile terminal device operates passively and forcibly receives a settlement process from a reader / writer, like a non-contact IC card. There is something like this.

In a mobile terminal device equipped with a non-contact communication unit, in the case where settlement processing of a non-contact IC card function is performed by proximity communication, in reality, a user can place a mobile terminal device body at a predetermined position. It needs to be held near the writer. For this reason, when performing input operation at the time of proximity | contact communication, it will operate in the state in which the portable terminal device left | separated considerably from the user's face. Therefore, it is difficult for a user to perform a selection operation such as a menu while watching the display on the screen of the mobile terminal device during a settlement process, etc. It is difficult to operate a specific button unless you are used to it. At present, such means as displaying information on the display unit on the reader / writer side or notifying the execution result of the process by sound is used.

  A mobile terminal device 100 of this embodiment shown in FIG. 1 has a function of a mobile phone device, and includes a terminal main body 10 and a non-contact communication unit 20 that is an IC card unit having a proximity communication function. The terminal body 10 includes a vibration detection unit 11, a vibration processing unit 12, a data storage unit 13, a data interpretation unit 14, a display unit 15, a display control unit 16, a control unit 17, a timer 18, And a portable terminal interface (I / F) 19. Note that FIG. 1 shows only some of the main elements of the mobile terminal device. Similar to a general mobile phone device, the mobile terminal device is connected to any other terminal device via a predetermined radio base station. The terminal body 10 further includes various components such as a wide-area communication function for wireless communication, a camera function for capturing an image of a subject, a mail function for sending and receiving electronic mail, and a network content browsing function. Various control functions on the terminal main body 10 can be realized by a dedicated electric circuit, or can be realized by a software program executed by a control computer.

  The non-contact communication unit 20 includes a data storage unit 21, an access management unit 22, a buffer 23, a carrier wave transmission / reception unit 24, a function stop processing unit 25, an IC card interface (I / F) 26, IC card control unit 27 is provided.

  The vibration detection unit 11 of the terminal body 10 is a sensor for detecting mechanical vibration applied to the casing of the mobile terminal device 100 by a user's tapping operation or the like. The vibration processing unit 12 recognizes the user's tapping operation by processing the signal detected by the vibration detection unit 11. The data storage unit 13 is a memory for temporarily storing received data, transmission target data, and the like. The data interpretation unit 14 divides the received data packet into a header and a data body, analyzes the contents of the data, and executes various processes according to the result.

  The display unit 15 displays various information in the mobile terminal device 100. For example, the display unit 15 displays a list of functions that can be executed on the mobile terminal device 100, and displays the balance and payment amount of electronic money held in the non-contact communication unit 20. The display control unit 16 performs processing of information displayed on the display unit 15 and drive control of the display device of the display unit 15.

  The control unit 17 has a function of an execution control unit, and executes various controls of each unit in the mobile terminal device 100 as a whole. The timer 18 is for measuring the time used for various operations. The mobile terminal interface 19 is an interface for connecting the terminal body 10 and the non-contact communication unit 20 and communicating between them.

  The data storage unit 21 of the non-contact communication unit 20 is a non-volatile memory for holding identification information of the IC card unit itself and value information such as electronic money. The access management unit 22 performs processing such as authentication processing and encryption / decryption in order to restrict access to information held in the data storage unit 21. The buffer 23 is a memory for temporarily holding data transmitted and received by the non-contact communication unit 20.

  The carrier transmission / reception unit 24 is for performing short-range wireless communication (proximity communication) using a high-frequency wireless signal (electromagnetic wave carrier), and includes an antenna and a transmission / reception circuit. For example, assuming a near field communication standard (Near Field Communication: NFC), the range of the distance that the carrier transceiver 24 can communicate is about 10 cm. In the case of a general terminal, proximity communication is performed using a carrier wave transmitted by a reader / writer that is a counterpart device. In this embodiment, in order to enable proximity communication between terminals, Similar to the reader / writer, the carrier wave transmitting / receiving unit 24 has a function of sending a carrier wave.

  The function stop processing unit 25 is for stopping the function of the non-contact communication unit 20 when proximity communication is not performed or under a predetermined condition. The IC card interface 26 is an interface for communicating between the non-contact communication unit 20 and the terminal body 10. The IC card control unit 27 performs overall control of the non-contact communication unit 20.

  Next, a specific example of the characteristic operation of the mobile terminal device 100 of the present embodiment will be described with reference to FIG. FIG. 2 shows the operation of a transmitting terminal having a function of transmitting a carrier wave.

  In step S11 of FIG. 2, it is identified whether or not a user's tapping operation has been detected. Specifically, it can be considered that the user's tapping operation is detected when the vibration detecting unit 11 detects mechanical vibration having a predetermined strength or more. Of course, the identification may be performed using not only the intensity but also a vibration intensity change pattern.

  In step S12, in order to confirm whether or not a partner device (terminal or reader / writer) for near field communication exists in the vicinity of the own device, the carrier transmission / reception unit 24 of the own device starts transmitting a carrier wave. When there is a partner device equipped with a near field communication function in the vicinity of its own device, the partner device can secure operating power using this carrier wave and can transmit and receive signals using this carrier wave. .

  In step S13, a predetermined partner confirmation command (polling) is transmitted on a carrier wave in order to confirm whether or not the partner device exists.

  In step S14, it is confirmed whether or not a response from the partner apparatus has been detected in response to the partner confirmation command sent in step S13. If a response is detected, the process proceeds to step S17, and if there is no response, the process proceeds to step S15.

  In step S15, it is identified whether or not a predetermined time (for example, 3 seconds) has elapsed since the partner confirmation command was first sent in step S13. If the predetermined time has not elapsed, the process returns to step S13 to continue sending the partner confirmation command. If there is no response from the counterpart device before the predetermined time has elapsed, the process proceeds to step S16.

  In step S16, the transmission of the carrier wave from the carrier wave transmitting / receiving unit 24 is stopped. Therefore, if only a hit operation (or simple vibration) is detected in step S11 and no response from the counterpart device is detected for a predetermined time, no special action is executed.

  When a hit operation is detected and a response from the counterpart device is detected, it is assumed that the execution condition is satisfied after successful authentication, and in step S17, short-range data communication by proximity communication using the carrier wave transmitting / receiving unit 24 is performed. And a predetermined operation using this short distance data communication is permitted.

  Next, an actual operation example of the present embodiment will be described with reference to FIG. In the example illustrated in FIG. 3, it is assumed that proximity communication is performed between the two mobile terminal devices 100A and 100B. In this example, the mobile terminal device 100A on one side (transmission side) has a carrier wave transmission function (reader / writer function) in the non-contact communication unit 20A, but the mobile terminal device 100B on the other side (reception side). Then, the non-contact communication unit 20B does not necessarily need a carrier wave transmission function, and only needs to have a reception function (card function) for receiving and communicating with the carrier wave of the counterpart device.

  Here, a case where image data is transferred is illustrated. First, in the mobile terminal device 100A that is a transfer source terminal, image data to be transmitted is prepared in the terminal body 10A and displayed on the display unit 15 (S101). The display screen of the display unit 15 at this time is, for example, as shown in FIG. Then, the user performs an operation of bringing the two mobile terminal devices 100A and 100B closer to each other and hitting them with the transfer-source mobile terminal device 100A.

  At this time, if the vibration detection unit 11 of the terminal main body 10A detects vibration in a state in which the counterpart mobile terminal device 100B is detected (S102), it is assumed that the execution condition is satisfied after successful authentication, and the proximity communication is performed. Start executing data transfer. The terminal body 10A sends a reader / writer function start request to the non-contact communication unit 20A (S103), and the non-contact communication unit 20A starts the reader / writer function and outputs a carrier wave for proximity communication (S104). On the other hand, in the portable terminal device 100B that is a transfer destination terminal, the card function is started in the non-contact communication unit 20B in the standby state, and a carrier wave is received (S105).

  In the mobile terminal device 100A, the terminal main body 10A sends a data write request including information on the transmission data type to the non-contact communication unit 20A (S106), and the non-contact communication unit 20A of the mobile terminal device 100A performs mobile communication by proximity communication. This data write request is transmitted to the non-contact communication unit 20B of 100B (S107). The non-contact communication unit 20B of the mobile terminal device 100B stores the received data in the buffer 23 (S108). Then, the terminal body 10B is notified of data reception from the non-contact communication unit 20B (S109). The terminal body 10B transmits a data read request to the non-contact communication unit 20B (S110), and takes in the data of the transmission data type from the buffer 23 (S111). Then, a screen during data reception or data transfer is displayed on the display unit 15 (S112). The display screen of the display unit 15 at this time is, for example, as shown in FIG. Note that the screen display during data transfer may be similarly performed on the transfer-source mobile terminal device 100A.

  When the mobile terminal device 100B successfully receives data, the non-contact communication unit 20B notifies the mobile terminal device 100A of a successful data write response (S113), and the data write success response is sent from the non-contact communication unit 20A to the terminal body. 10A (S114). Subsequently, a data write request including real data information is sent from the terminal body 10A to the non-contact communication unit 20A (S115), and the non-contact of the mobile terminal device 100B is performed by proximity communication from the non-contact communication unit 20A of the mobile terminal device 100A. This data write request is transmitted to the communication unit 20B (S116). The non-contact communication unit 20B of the mobile terminal device 100B stores the received data in the buffer 23 (S117). Then, this procedure is repeated until the transfer of the target image data is completed.

  In the transfer destination portable terminal device 100B, when the reception of the image data is completed, the received image data is displayed on the display unit 15 (S118). At this time, for example, image data is displayed on the display screen as in FIG. When the transmission of the mobile terminal device 100A completes the transmission of the image data and receives a response to the successful data writing from the mobile terminal device 100B, the display on the display unit 15 is deleted (S119).

  That is, when an operation of tapping with the two portable terminal devices 100A and 100B approaching each other, step S17 in FIG. 2 is executed, and data transfer by proximity communication is permitted. Note that the specific contents of the operation sequence as shown in FIG. 3 can be changed as appropriate in accordance with various needs, communication standards, and the like according to applications.

  In the operation example shown in FIG. 2, it is assumed that the non-contact communication unit 20 of the mobile terminal device 100 has a carrier wave sending function. However, a general non-contact communication IC card has a carrier wave sending function. Proximity communication is performed using a carrier wave that is not mounted and is transmitted by a reader / writer that is the counterpart device. When the carrier wave transmission function is not installed, the mobile terminal device 100 may perform the operation shown in FIG. 5 instead of the operation shown in FIG. FIG. 5A shows an operation when a carrier wave is detected in the non-contact communication unit, and FIG. 5B shows an operation when a user tapping operation is detected in the terminal body.

  In step S21 of FIG. 5A, it is identified whether or not the non-contact communication unit 20 of the own device has detected a carrier wave from the partner device (reader / writer or terminal). If the distance between the own device and the partner device is short and the partner device is transmitting a carrier wave, the carrier wave can be detected in step S21.

  In step S22, a carrier wave from the partner device is modulated by a signal for responding to polling from the partner device, and this signal is transmitted. In step S23, time information corresponding to the current time is recorded. As a result, the fact that the partner device of the near field communication exists in the vicinity of the own device is retained as a record.

  On the other hand, in step S26 of FIG. 5B, it is identified whether or not a user's tapping operation has been detected. Specifically, it can be considered that the user's tapping operation is detected when the vibration detecting unit 11 detects mechanical vibration having a predetermined strength or more.

  If an operation of tapping is detected in step S26, it is checked in the next step S27 whether a partner device for proximity communication has been detected within the past predetermined time (for example, 3 seconds). Specifically, it can be checked by comparing the time recorded last in step S23 described above with the current time. If a partner device for near field communication is detected within the past predetermined time, the process proceeds from step S27 to step S28. In step S28, near field data communication by near field communication using the carrier wave transmitting / receiving unit 24 is permitted, and a predetermined operation using this near field data communication is permitted.

  Moreover, in step S24 of Fig.5 (a), it is confirmed whether the predetermined | prescribed operation | movement accompanying short-distance wireless data communication is permitted. If a hit operation is detected when a partner device for near field communication is present in the vicinity of the own device, the operation is permitted in step S28 described above, and the process proceeds from step S24 to step S25. On the other hand, the operation is not permitted only if the partner device for the near field communication exists in the vicinity of the own device, and the operation is not permitted only by detecting the tapping operation. In step S25, a predetermined operation involving short-range wireless data communication is executed.

  As described above, in the present embodiment, when the user performs an operation of tapping on the portable terminal device, or before or after the operation, a partner device for proximity communication (for example, a reader / writer for a non-contact communication IC card or non-contact communication). Only when a terminal having a function exists in the vicinity (within a communicable range), a predetermined operation involving the communication is executed. As a result, when the user wants to perform a predetermined operation by proximity communication, in this case, data communication, the user only hits the casing of the terminal or hits the casing of the terminal against some object to generate mechanical vibration. Thus, the input operation for confirmation can be easily completed, and the terminal can perform processing without referring to the display on the screen and performing a selection operation or operating a special button.

  Also, if the user unintentionally hits his / her terminal against an obstacle or drops the terminal, the terminal may mistakenly recognize it as an operation to hit the mechanical vibration generated by it. There is. However, at that time, immediately before or immediately after that, there is a high possibility that the partner device for the near field communication does not exist in the vicinity, so data communication or the like is not executed. For this reason, the operation | movement which a user does not intend can be prevented and the safety | security with respect to the outflow of data etc. is ensured.

  Therefore, according to the present embodiment, when various functions using proximity communication are executed by the non-contact communication unit, it is possible to easily perform the operation of the function according to the user's intention, thereby improving the operability. It becomes possible.

(Second Embodiment)
FIG. 6 is a sequence diagram illustrating an operation example of near field communication using the mobile terminal device according to the second embodiment. FIG. 7 is a diagram showing an example of a display screen in the second embodiment.

  The second embodiment is a modification of the first embodiment, and the basic configuration of the mobile terminal device 100 is the same as that of the first embodiment shown in FIG. However, in the second embodiment, the non-contact communication unit 20 of the mobile terminal device 100 does not have a carrier wave transmission function, and value information such as electronic money is stored in the data storage unit 21 of the non-contact communication unit 20. It shall be retained.

  Here, an actual operation example of the present embodiment will be described with reference to FIG. In the example illustrated in FIG. 6, it is assumed that proximity communication is performed between the mobile terminal device 100 and the counterpart device 200. As the specific partner device 200, for example, a reader / writer mounted on various devices that require monetary settlement such as train ticket gates, game machines, pachinko machines, and vending machines is used. Since the mobile terminal device 100 is not equipped with a carrier wave transmission function, the mobile terminal device 100 performs the same operation as in FIG.

  Here, a case where settlement processing such as electronic money is executed is illustrated. First, when the user brings the mobile terminal device 100 close to the counterpart device 200 having the reader / writer function, the mobile terminal device 100 starts a card function in the standby state and receives a carrier wave (S301). ). When the partner device 200 detects the communication partner mobile terminal device 100, the partner device 200 sends a data write request including an IC command for unlocking the settlement function of the non-contact communication unit 20 and message information to the non-portable terminal 100. It transmits to the contact communication part 20 (S302). Since value information such as electronic money held in the data storage unit 21 on the non-contact communication unit 20 is locked so that it cannot be normally accessed for safety measures, settlement processing is performed using the electronic money. At that time, it is necessary to unlock the settlement function of the non-contact communication unit 20 in advance.

  The non-contact communication unit 20 of the portable terminal device 100 stores the received data in the buffer 23 (S303). Then, the terminal body 10 is notified of data reception from the non-contact communication unit 20 (S304). The terminal body 10 transmits a data read request to the non-contact communication unit 20 (S305), and takes in the unlocked IC command and message data from the buffer 23 (S306). Then, a response to successful data reception is transmitted from the non-contact communication unit 20 to the partner apparatus 200 (S307), a confirmation screen for electronic money settlement is displayed on the display unit 15, and input from the user is requested (S308). The display screen of the display unit 15 at this time is, for example, as shown in FIG. This display screen is used to confirm payment of electronic money.

  At this time, when the user performs an operation of holding and hitting the mobile terminal device 100 and detecting an operation of hitting by the vibration detection unit 11 of the terminal body 10 as in the operation illustrated in FIG. 5 (S309), in this case Since the carrier wave from the partner device 200 is being detected, it is recognized that the authentication has succeeded and the execution condition is satisfied, and the user's confirmation is obtained. And the IC command which instruct | indicates unlocking is transmitted with respect to the non-contact communication part 20 from the terminal main body 10 (S310). In response to the IC command for unlocking, the non-contact communication unit 20 unlocks operations such as reading and writing with respect to the data storage unit 21 in the IC card unit, and switches to a state where the value information can be accessed (S311). Then, a response indicating that the lock has been released is returned to the terminal body 10 (S312).

  In this state, the partner device 200 transmits a predetermined value operation command related to electronic money settlement as an IC command to the non-contact communication unit 20 of the mobile terminal device 100 existing in the vicinity (S313). By this value operation command, data is read from and written to the non-contact communication unit 20 by non-contact communication, and value reduction processing is performed (S314). When the value reduction process is normally completed, a response indicating that the process is successful is transmitted from the non-contact communication unit 20 to the partner apparatus 200 (S315). Note that when the lock is not released in the non-contact communication unit 20, the process related to the value information is rejected, and the access from the partner apparatus 200 fails.

  Further, the terminal body 10 of the mobile terminal device 100 waits for a certain period of time after receiving a response to the unlocking IC command (S316), and transmits an operation locking IC command related to the function of the non-contact communication unit 20 after a certain period of time has elapsed. (S317). Then, the non-contact communication unit 20 executes again locking of operations such as reading and writing with respect to the data storage unit 21 in the IC card unit (S318).

  In the above-described operation example, when the operation of the data storage unit 21 in the IC card unit is unlocked by vibration detection, the lock is performed again after a predetermined time has elapsed. However, other methods are also conceivable. For example, when the vibration is detected by the user performing another tapping operation after unlocking, the lock may be applied again. As a result, the user can unlock the IC card unit only during an intended period, and security can be improved.

  As described above, in this embodiment, immediately after the user taps the mobile terminal device, the mobile terminal device is brought close to the counterpart device, or the mobile terminal device is hit close to the counterpart device, or the mobile terminal device is carried. A payment process using electronic money or the like is executed by causing the terminal device to contact with a nearby device to generate mechanical vibration. For this reason, when performing a predetermined operation by proximity communication, in this case, payment processing, the user only hits the casing of the terminal or generates mechanical vibration by hitting the casing of the terminal against some object Thus, the input operation for confirmation can be easily completed, and the terminal can perform processing without referring to the display on the screen or operating a special button. However, if the user does not intend to confirm the payment process, for example, when the user unconsciously hits the mobile terminal device against some object or drops the mobile terminal device, the mobile terminal Since the partner device does not exist in the vicinity of the device, the lock of the non-contact communication unit is not released, the payment process unintended by the user can be prevented, and safety is ensured.

(Third embodiment)
FIG. 8 is a flowchart illustrating an operation example of the mobile terminal device according to the third embodiment. FIG. 9 is a sequence diagram illustrating an operation example of near field communication using the mobile terminal device according to the third embodiment. FIG. 10 is a diagram showing an example of a display screen in the third embodiment.

  The third embodiment is a modification of the second embodiment, and the basic configuration of the mobile terminal device 100 is the same as that of the first embodiment shown in FIG. Also in the third embodiment, as in the second embodiment, the non-contact communication unit 20 of the mobile terminal device 100 does not have a carrier wave transmission function, and the data storage unit 21 of the non-contact communication unit 20 includes an electronic device. It is assumed that value information such as money is held.

  Here, a specific example of the characteristic operation of the mobile terminal device 100 of the present embodiment will be described with reference to FIG. FIG. 8A shows an operation when a carrier wave is detected in the non-contact communication unit, and FIG. 8B shows an operation when a user tapping operation is detected in the terminal body.

  In step S51 of FIG. 8A, it is identified whether or not the non-contact communication unit 20 of the mobile terminal device 100 has detected a carrier wave from the partner device (reader / writer). If the partner apparatus is in the vicinity of the own apparatus and the partner apparatus is transmitting a carrier wave, the carrier wave is detected, and the process proceeds to the next step S52.

  In step S <b> 52, the non-contact communication unit 20 receives the data sent from the counterpart device and records it in the buffer 23. In the next step S53, the non-contact communication unit 20 communicates with the terminal body 10.

  On the other hand, in step S58 of FIG. 8B, it is identified whether or not the user's tapping operation is detected in the terminal body 10. When a tapping operation from the user is detected, in this case, since the carrier wave from the partner apparatus 200 is detected, it is assumed that the execution condition is satisfied after successful authentication, and the process proceeds to the next step S59. In step S59, it is confirmed whether or not a request for unlocking has been received from the non-contact communication unit 20. Here, when the terminal body 10 receives a request for unlocking from the non-contact communication unit 20, the terminal body 10 transmits a lock release command to the non-contact communication unit 20 in the next step S60.

  At this time, the non-contact communication unit 20 confirms whether or not a lock release command is received from the terminal body 10 in step S54 of FIG. When the unlock command is received, the process proceeds from step S54 to step S55.

  In step S55, according to the unlock command received from the terminal body 10, the non-contact communication unit 20 unlocks access to the value information on the data storage unit 21. However, in this embodiment, the value that can be reduced at a time is limited to a certain amount (for example, equivalent to 100 yen). Even if a sufficient amount of value (electronic money) exists on the data storage unit 21, the upper limit of the value that can be reduced by unlocking is limited to a predetermined amount.

  In step S56, when the value operation command is received from the counterpart device, the lock function is unlocked in the previous step S55, and the value reduction process is executed in accordance with the instruction from the counterpart device. However, the value to be reduced is limited to a certain amount.

  When the value reduction process is completed in step S56 or when a predetermined time has elapsed since the settlement function was unlocked, the process proceeds to step S57, and the lock on the value information in the data storage unit 21 is executed again.

  In the terminal body 10, when a tapping operation is detected, the process proceeds from step S <b> 58 through S <b> 59 to S <b> 60, so that a lock release command is sent to the non-contact communication unit 20 every time a tapping operation is detected. For this reason, for example, when paying while counting cash coins one by one, a certain amount of payment can be executed from electronic money each time the portable terminal device 100 is tapped.

  Next, an actual operation example of the present embodiment will be described with reference to FIG. In the example illustrated in FIG. 9, as in the case of FIG. 6, it is assumed that the settlement processing is performed by performing near field communication between the mobile terminal device 100 and the counterpart device 200.

  Similar to the second embodiment described above, a request for electronic money is sent from the counterpart device 200 to the mobile terminal device 100 by a data write request including an IC command for unlocking the settlement function of the non-contact communication unit 20. It transmits to the non-contact communication part 20 (S501). Here, payment of electronic money of 100 yen is requested from the counterpart device 200.

  In the mobile terminal device 100, a payment function acceptance process is executed as in the second embodiment, a confirmation screen for electronic money payment is displayed on the display unit 15, and input from the user is requested (S502). The display screen of the display unit 15 at this time is, for example, as shown in FIG. This display screen shows the value of 100 yen paid in one operation and the current remaining amount of 2000 yen, and confirms the payment of electronic money.

  At this time, when the user performs an operation of holding and hitting the mobile terminal device 100 and detecting an operation of hitting by the vibration detection unit 11 of the terminal body 10 (S503), the carrier wave from the counterpart device 200 is detected. Recognizing that the user's confirmation has been obtained, the payment function of the non-contact communication unit 20 is unlocked as in the second embodiment. And the response which permits payment of electronic money is transmitted to the other apparatus 200 (S504). Upon receiving the response from the mobile terminal device 100, the counterpart device 200 performs data communication by proximity communication to the non-contact communication unit 20 of the mobile terminal device 100 in the same manner as in the second embodiment, and the value of electronic money is obtained. By reducing the fixed amount (100 yen), the amount is charged (S505). Thereby, payment of 100 yen of electronic money is executed with a single tapping operation.

  And the process of said S501-S505 is repeated. In the second operation, the display screen of the display unit 15 is as shown in FIG. 10B, for example, and the remaining amount is reduced by 100 yen from the previous time. At this time, the user can instruct electronic money payment while checking the remaining amount each time.

  As described above, according to the present embodiment, payment of electronic money is executed by a predetermined amount as if a user inserts a coin while confirming each time by performing an operation of hitting the mobile terminal device. Can do. For this reason, it is possible for the user to easily grasp the amount of payment, and it is also possible to recognize the amount of payment by the number of operations without looking at the amount display on the display screen. It is also possible to prevent a large amount of payment from being executed unintentionally, such as a large amount of payment being made at once.

  As described above, by applying the present invention to a mobile terminal device having a proximity communication function, it is extremely simple even without referring to the screen display and performing a selection operation or operating a specific button. A predetermined function can be executed by performing an instruction operation or a confirmation operation by a tapping operation. Such a tapping operation is possible in extending the operation of bringing the non-contact communication unit of the portable terminal device closer to the counterpart device such as a reader / writer or another terminal, and does not require a troublesome operation. is there. In addition, the user can perform execution confirmation such as data transfer and electronic money settlement by intuitive operation. At this time, the non-contact communication unit can perform proximity communication by receiving and starting a carrier wave from the partner device, or sending a carrier wave from the own device to start the partner device.

  In addition, since the process is not executed when the partner device of the near field communication is not in the vicinity, it is possible to prevent the process from being executed against the user's intention, and against the outflow or rewriting of information such as electronic money. And sufficient safety can be ensured. Therefore, the operation of the function according to the user's intention can be easily performed, and the operability can be improved.

  Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention.

  According to the present invention, when various functions using proximity communication are executed by the non-contact communication unit, it is possible to easily perform the operation of the function according to the user's intention, and it is possible to improve the operability. It is effective for a portable terminal device having a proximity communication function for effecting contactless communication with other devices existing at a relatively close distance.
