A return function, a fast-forward function, a volume down operation, a volume up operation, a playback operation, a pause operation, and the like are executed.

  FIG. 3 shows an internal configuration of the mobile phone 1 in the present embodiment.

  A radio signal transmitted from a base station (not shown) is received by an antenna 31 and then input to a receiving circuit (RX) 33 via an antenna duplexer (DUP) 32. The receiving circuit 33 mixes the received radio signal with the local oscillation signal output from the frequency synthesizer (SYN) 34 and converts the frequency into an intermediate frequency signal (down-conversion). Then, the reception circuit 33 orthogonally demodulates the down-converted intermediate frequency signal and outputs a reception baseband signal. The frequency of the local oscillation signal generated from the frequency synthesizer 34 is instructed by a control signal SYC output from the control unit 41.

  The reception baseband signal from the reception circuit 33 is input to the CDMA signal processing unit 36. The CDMA signal processing unit 36 includes a RAKE receiver (not shown). In this RAKE receiver, a plurality of paths included in the received baseband signal are despread with each spreading code (that is, the same spreading code as that of the spread received signal). Then, the signals of the respective paths subjected to the despreading process are subjected to coherent Rake synthesis after the phase is adjusted. The data sequence after Rake combining is subjected to deinterleaving and channel decoding (error correction decoding), and then binary data determination is performed. Thereby, received packet data of a predetermined transmission format is obtained. This received packet data is input to the compression / decompression processor 37.

  The compression / decompression processing unit 37 is configured by a DSP (Digital Signal Processor) or the like, and the received packet data output from the CDMA signal processing unit 36 is separated for each medium by a demultiplexing unit (not shown), and for each separated medium. The decryption process is performed for each. For example, in the call mode, audio data corresponding to call voice included in the received packet data is decoded by a speech codec. Also, if the received packet data includes moving image data, such as the videophone mode, this moving image data is decoded by a video codec. Further, if the received packet data is a download content, the download content is decompressed, and then the decompressed download content is output to the control unit 41.

  The digital audio signal obtained by the decoding process is supplied to the PCM codec 38. The PCM codec 38 PCM-decodes the digital audio signal output from the compression / decompression processor 37 and outputs the analog audio data signal after PCM decoding to the reception amplifier 39. The analog audio signal is amplified by the reception amplifier 39 and then output from the receiver 18.

  The digital moving image signal decoded by the video codec by the compression / decompression processing unit 37 is input to the control unit 41. The control unit 41 displays a moving image based on the digital moving image signal output from the compression / decompression processing unit 37 on the main display 17 via a video RAM (for example, a VRAM) (not shown). The control unit 41 can display not only the received moving image data but also the moving image data captured by the CCD camera 20 on the main display 17 via a video RAM (not shown).

  Further, when the received packet data is an electronic mail, the compression / decompression processing unit 37 supplies the electronic mail to the control unit 41. The control unit 41 stores the electronic mail supplied from the compression / decompression processing unit 37 in the storage unit 42. Then, the control unit 41 reads out the electronic mail stored in the storage unit 42 in accordance with the operation of the operation key 14 as an input unit by the user, and displays the read electronic mail on the main display 17.

  On the other hand, in the call mode, the voice signal (analog audio signal) of the speaker (user) input to the microphone 15 is amplified to an appropriate level by the transmission amplifier 40 and then PCM encoded by the PCM codec 38. The digital audio signal after the PCM encoding is input to the compression / decompression processing unit 37. The moving image signal output from the CCD camera 20 is digitized by the control unit 41 and input to the compression / decompression processing unit 37. Further, an electronic mail which is text data created by the control unit 41 is also input to the compression / decompression processing unit 37.

  The compression / decompression processor 37 compresses and encodes the digital audio signal output from the PCM codec 38 in a format corresponding to a predetermined transmission data rate. Thereby, audio data is generated. The compression / decompression processing unit 37 compresses and encodes the digital moving image signal output from the control unit 41 to generate moving image data. Then, the compression / decompression processing unit 37 multiplexes these audio data and moving image data by a demultiplexing unit (not shown) according to a predetermined transmission format and then packetizes them, and the packetized transmission packet data is transmitted to the CDMA signal processing unit 36. Output to. Note that the compression / decompression processing unit 37 also multiplexes the e-mail into the transmission packet data even when the e-mail is output from the control unit 41.

  The CDMA signal processing unit 36 performs spread spectrum processing on the transmission packet data output from the compression / decompression processing unit 37 using a spreading code assigned to the transmission channel, and transmits the output signal after the spread spectrum processing to the transmission circuit ( TX) 35. The transmission circuit 35 modulates the signal after the spread spectrum processing using a digital modulation method such as a QPSK (Quadrature Phase Shift Keying) method. The transmission circuit 35 combines the digitally modulated transmission signal with a local oscillation signal generated from the frequency synthesizer 34 and frequency-converts (up-converts) the signal into a radio signal. Then, the transmission circuit 35 amplifies the radio signal generated by this up-conversion with high frequency so that the transmission power level instructed by the control unit 41 is obtained. The radio signal amplified by the high frequency is supplied to the antenna 31 via the antenna duplexer 32 and transmitted from the antenna 31 to a base station (not shown).

  The mobile phone 1 also includes an external memory interface 45. The external memory interface 45 has a slot into which the memory card 46 can be attached and detached. The memory card 46 is a type of flash memory card typified by a NAND flash memory card or a NOR flash memory card, and can write and read various data such as images, sounds and music via a 10-pin terminal. It has become. Further, the mobile phone 1 is provided with a clock circuit (timer) 49 for measuring the current accurate current time.

  The mobile phone 1 is provided with an infrared communication unit 47 and a Bluetooth communication unit 48 as short-range wireless transmission means and short-range wireless reception means. The infrared communication unit 47 is a short-range wireless communication unit using, for example, an IrDA (Infrared Date Association) system. The infrared communication unit 47 is connected to an opposite device such as a mobile phone located in a short distance of about 0.2 to 1 m, and the mobile phone 1. Various data such as self profile information and image data stored in the storage unit 42 are transmitted and received. The data to be transmitted may be not only data stored in the storage unit 42 but also data stored in the memory card 46.

  The Bluetooth communication unit 48 is a short-range wireless communication unit using a wireless communication method referred to as Bluetooth. The Bluetooth communication unit 48 can be easily connected to a mobile phone or the like equipped with other Bluetooth, and transmits and receives data and voice in the short distance of about 10 m, for example, in the same manner as the infrared communication unit 47.

  The control unit 41 includes a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM). The CPU is loaded into the RAM from a program stored in the ROM or the storage unit 42. Various processes are executed in accordance with various application programs, and various control signals are generated and supplied to each unit to control the mobile phone 1 in an integrated manner. The RAM appropriately stores data necessary for the CPU to execute various processes.

  The storage unit 42 includes, for example, a flash memory element that is an electrically rewritable and erasable nonvolatile memory, an HDD (Hard Disc Drive), and the like, and various application programs executed by the CPU of the control unit 41 and various types The data group is stored. The power supply circuit 44 generates a predetermined operating power supply voltage Vcc based on the output of the battery 43 and supplies it to each circuit unit.

  Here, functions of the third keys 16a and 16b as transmission mode activation means and reception mode activation means provided on the side surface of the first casing 12 of the mobile phone 1 will be described.

  In the present embodiment, when the mobile phone 1 is closed and the side keys 16a and 16b are pressed, the infrared communication unit 47 and the Bluetooth communication unit 48 activate the transmission mode and the reception mode based on the control of the control unit 41. Is assigned to run.

  The transmission mode activated by the infrared communication unit 47 and the Bluetooth communication unit 48 in the present embodiment refers to a state in which predetermined data set in advance to the opposite device can be transmitted by pressing the side keys 16a and 16b. The reception mode activated by the infrared communication unit 47 and the Bluetooth communication unit 48 refers to a state in which data transmitted from the opposite device can be received by pressing the side keys 16a and 16b.

  The predetermined data transmitted to the opposite device when the transmission mode is activated can be arbitrarily set by the user. However, in this embodiment, the user's own profile information (the user's own name) that is considered to be frequently transmitted. , Information such as telephone numbers and e-mail addresses) is applied to predetermined data.

  As an example, the transmission mode in the present embodiment is activated by the infrared communication unit 47 when the side key 16a is pressed for a short time, and the transmission mode by the Bluetooth communication function 48 when the side key 16a is pressed for a long time. Configured to boot. Similarly, as an example, when the side key 16b is short-pressed, the reception mode by the infrared communication unit 47 is activated, and when the side key 16b is long-pressed, the reception mode by the Bluetooth communication function 48 is activated, When the side keys 16a and 16b are pressed at the same time, the reception mode by both the infrared communication unit 47 and the Bluetooth communication unit 48 is activated.

  The transmission / reception modes that are activated by distinguishing the pressing lengths of the side keys 16a and 16b are merely examples. For example, the user can change the assignment of the side keys 16a and 16b at any time. Alternatively, it may be configured so that selection can be made after pressing the side keys 16a and 16b.

  Here, a conventional data transmission / reception process using the infrared communication function and the Bluetooth communication function will be described.

  FIG. 4 is a flowchart for explaining a conventional example of a process in which the mobile phone 1 transmits data to an opposite device such as a mobile phone having an infrared communication function, along with an example of an operation performed by the user. The data to be transmitted is profile information (information such as the user's own name, telephone number, and mail address) stored in the mobile phone 1. It can be said that this profile information is frequently transmitted and received using the short-range wireless communication function, such as mutual transmission and reception at the first meeting. The profile transmission process starts from a normal standby state (sleep state) with the cellular phone 1 in a closed state as shown in FIG.

  In step S1, the user opens the cellular phone 1 in the closed state, and opens it at about 180 degrees as shown in FIG. 1 (operation 1). As a result, the backlight of the main display 17 of the mobile phone 1 is turned on, and the current time and the like are displayed. In step S2, the user presses the menu key in the operation key 14 to display a menu selection screen on the main display 17 (operation 2). The control unit 41 that has received an input by pressing the menu key on the operation key 14 displays a menu list that is a menu selection screen on the main display 17. In step S3, the user selects profile information from the menu list displayed on the menu selection screen by pressing the cross key and the enter key on the operation key 14 (operation 3). Specifically, the user moves the cursor to the profile information by operating the cross key up / down / left / right, and then presses the enter key. The control unit 41 that has received an input by pressing the cross key and the confirmation key displays the user profile information stored in the storage unit 42 of the mobile phone 1 on the main display 17.

  In step S4, the user displays the submenu selection screen by pressing the submenu key in the operation key 14 assigned to start the submenu selection screen (operation 4). The control unit 41 that has received an input by pressing the submenu key displays a submenu list that is a submenu selection screen on the main display 17. In step S5, the user selects the infrared transmission mode by pressing the cross key and the enter key on the operation key 14 from the submenu list displayed on the submenu selection screen (operation 5). Specifically, the user moves the cursor to the infrared transmission mode by operating the cross key up / down / left / right, and then presses the enter key. The control unit 41 that has received an input by pressing the cross key and the confirmation key displays an infrared transmission mode screen on the main display 17, and the infrared communication unit 47 activates the transmission mode.

  In step S <b> 6, the infrared communication unit 47 confirms a counter device such as a mobile phone that is a connection destination as a transmission destination of profile information. When the opposing device that is the connection destination is confirmed, the infrared communication unit 47 starts transmitting profile information to the opposing device in step S7. After completing the transmission of the profile information, the series of processing ends, and the main display 17 shifts to a normal standby screen.

  On the other hand, in the connection destination confirmation step S6, the infrared communication unit 47 times out because it cannot confirm the opposite device to which the profile information is connected, and in step S8, the control unit 41 receives an input of an instruction to retry. In this case, the process returns to the connection destination confirmation step S6, and the processes after step S6 are performed again. On the other hand, when the control unit 41 receives an input of an instruction not to retry, the series of processing ends and the normal standby screen is displayed. The input of the instruction as to whether or not to perform the retry executed in the retry determination step S8 is performed, for example, when the user operates a predetermined operation key 14 on the retry confirmation screen displayed on the main display 17 by the control unit 41. Done.

  Next, a data reception process using a conventional infrared communication function and Bluetooth communication function will be described.

  FIG. 5 is a flowchart for explaining a conventional example of processing in which the mobile phone 1 receives data transmitted from an opposite device such as a mobile phone having a Bluetooth communication function, along with an example of an operation performed by the user. Similar to the transmission processing described with reference to FIG. 4, the received data is, for example, profile information. Also, this data transmission process starts from a normal standby state (sleep state) with the cellular phone 1 in a closed state as shown in FIG.

  In step S11, the user opens the cellular phone 1 in the closed state, and opens it at about 180 degrees as shown in FIG. 1 (operation 1). As a result, the backlight of the main display 17 of the mobile phone 1 is turned on, and the current time and the like are displayed. In step S12, the user presses the menu key in the operation key 14 to activate the menu selection screen (operation 2). The control unit 41 that has received an input from the input unit by pressing the menu key displays a menu list that is a menu selection screen on the main display 17. In step S13, the user selects the Bluetooth menu from the menu list displayed on the menu selection screen by pressing the cross key and the enter key on the operation key 14 (operation 3). Specifically, the user moves the cursor to the Bluetooth menu by operating the cross key up / down / left / right, and then presses the enter key. The control unit 41 that has received an input by pressing the cross key and the confirmation key displays a Bluetooth menu selection screen on the main display 17.

  In step S14, the user selects the Bluetooth reception mode by pressing the cross key and the confirmation key on the operation key 14 from the Bluetooth menu list displayed on the Bluetooth menu selection screen (operation 4). Specifically, the user moves the cursor to the Bluetooth reception mode by operating the cross key up / down / left / right, and then presses the enter key. The control unit 41 that has received an input by pressing the cross key and the confirmation key displays a Bluetooth reception mode screen on the main display 17, and the Bluetooth communication unit 48 activates the Bluetooth reception mode.

  In step S15, the Bluetooth communication unit 48 receives device information such as another mobile phone that is the transmission source of the profile information. When the opposing device information is received and the connection is established, in step S16, the Bluetooth communication unit 48 starts receiving profile information transmitted from the opposing device such as a mobile phone. After completing the reception of the profile information, in step S17, the control unit 41 receives an input of an instruction as to whether or not to continue the Bluetooth reception mode. When the control unit 41 receives an input of an instruction to end the reception mode, the series of processing ends, and the main display 17 shifts to a normal standby screen. On the other hand, when the control unit 41 receives an input of an instruction to continue the reception mode, the process returns to the device information reception step S15, and the processes after step S15 are performed again. Note that the instruction to continue the Bluetooth reception mode is input, for example, when the user operates a predetermined operation key 14 on the confirmation screen for continuation of the Bluetooth reception mode displayed on the main display 17 by the control unit 41.

  On the other hand, in the device information receiving step S15, the counter device information such as the mobile phone that is the transmission source of the profile information is not received and the connection is not established, and the control unit 41 performs a retry in step S18. When the input of the instruction is accepted, the process returns to the device information receiving step S15, and the processes after step S15 are performed again. On the other hand, when the control unit 41 receives an instruction not to retry in the retry determination step S18, the series of processing ends and the normal standby screen is displayed. The input of the instruction whether or not to perform the retry executed in the retry determination step S18 is performed by, for example, the user operating a predetermined operation key 14 on the retry confirmation screen displayed on the main display 17 by the control unit 41. Done.

  FIG. 6 is a flowchart for explaining a conventional example of processing for receiving data from a counter device such as a mobile phone having an infrared communication function, together with an example of an operation performed by a user. Steps S21 to S24 in the reception process using the infrared communication function are substantially the same as steps S11 to S14 in the reception process using the Bluetooth communication function described with reference to FIG.

  In step S25, the infrared communication unit 47 confirms an opposite device such as a mobile phone that is a connection destination as a transmission source of data such as profile information. When the opposite device is confirmed, in step S26, the infrared communication unit 47 starts receiving data such as profile information transmitted from the opposite device such as a mobile phone. After data reception is completed, the series of processing ends and the normal standby screen is displayed.

  On the other hand, in step S25, the infrared communication unit 47 times out because it cannot check the opposite device that is the connection destination as a data transmission source such as profile information. In step S27, the control unit 41 instructs to retry. When the input is accepted, the process returns to S25, which is a connection destination confirmation step, and the processes after Step S25 are performed again. On the other hand, when the control unit 41 receives an input of an instruction not to retry, the series of processing ends and the normal standby screen is displayed.

  Incidentally, as described with reference to FIG. 4, when the profile information is transmitted to the opposite device such as a mobile phone, the operation that the user has to perform in order to activate the infrared transmission mode by the infrared communication unit 47 is described in Steps S1 to S1. Five operations of operations 1 to 5 corresponding to S5 are required. Further, as described with reference to FIGS. 5 and 6, when receiving profile information transmitted from the opposite device, the user must perform in order to activate the reception mode by the infrared communication unit 47 and the Bluetooth communication unit 48. The operation requires four operations of operations 1 to 4 corresponding to steps S11 to S14 and steps S21 to S24.

  For this reason, even when each transmission / reception mode of frequently used profile information is activated, a complicated operation is required in the first place to cause user stress. Further, since the backlight of the main display 17 having a large power consumption is lit until a series of transmission / reception processes are completed after the cellular phone 1 is in an open state, the power consumption of the cellular phone 1 is increased. As a result, there is a problem that the battery life of the mobile phone 1 is deteriorated.

  Therefore, the transmission / reception mode realized by the infrared communication unit 47 and the Bluetooth communication unit 48 is activated even when the cellular phone 1 is not opened as shown in FIG. 1 and is closed as shown in FIG. Thus, it is possible to improve operability and save power. Hereinafter, data transmission / reception processing by the mobile phone 1 in the present embodiment will be described.

  FIG. 7 is a flowchart for explaining processing for transmitting data to a counter device such as a mobile phone having an infrared communication function using the mobile phone 1 according to the present embodiment, along with an example of an operation performed by the user. . The data to be transmitted will be described as profile information stored in the storage unit 42 of the mobile phone 1 as an example. Note that all the mobile phones 1 in the data transmission process are executed in a closed state as shown in FIG. 2, and this data transmission process starts from a normal standby state (sleep state).

  In step S31, the user presses (short presses) the side key 16a to activate the infrared transmission mode (operation 1). The control unit 41 that has received an input by pressing the side key 16a by the user controls the infrared communication unit 47 in step S32, and the infrared communication unit 47 activates the infrared transmission mode. At this time, the control unit 41 controls the sub display 21 and displays the state of the infrared transmission mode on the sub display 21. FIG. 8A is a display example of the sub-display 21 indicating that the infrared mode is being activated.

  In step S33, the infrared communication unit 47 confirms a counter device such as a mobile phone that is a connection destination as a transmission destination of profile information. When the opposing device that is the connection destination is confirmed, the infrared communication unit 47 starts transmitting profile information to the opposing device according to the control of the control unit 41 in step S34. FIG. 8B is a display example of the sub-display 21 during profile information transmission. After the transmission of the profile information is completed, the series of processing ends, and the sub display 21 shifts to a normal standby screen. FIG. 8C is a display example of the sub-display 21 when the transmission of the profile information is completed.

  On the other hand, in the connection destination confirmation step S33, the processing when the infrared communication unit 47 times out because it cannot confirm the other mobile phone to which the profile information is transmitted is the same as the processing after step S8 described in FIG. Therefore, detailed description is omitted. In step S35, the control unit 41 notifies the user by displaying on the sub-display 21 whether or not to continue the time-out notification and the connection destination confirmation as shown in FIG. To do. The user who has received this notification inputs an instruction as to whether or not to retry. The input of the instruction can be configured such that “Yes” and “No” shown in FIG. 8D can be selected by, for example, the rewind and fast forward buttons of the electrostatic touch pad 22. Moreover, it can also comprise so that selection is possible with the side keys 16a and 16b.

  According to the cellular phone 1, the five operations that were conventionally required to activate the transmission mode may be a single simple operation of only pressing the side key in step S31. Can be improved. For this reason, even when transmitting and receiving a self profile that is frequently used, it can be executed with a simple operation, so that user stress can be reduced and the elder layer can be executed without any complicated operation.

  Further, since data can be transmitted while the cellular phone 1 is in the closed state, the transmission mode state can be displayed only on the sub display 21 without using the main display 17. As a result, an increase in power consumption due to the backlight of the main display 17 with high power consumption can be suppressed, and power saving of the mobile phone 1 can be achieved.

  Note that the sub display 21 functions as a display unit and the backlight is turned on when the transmission mode activation state shown in FIG. 8A in the transmission mode activation step S32 described in FIG. 7 is displayed. When the transmission state shown in FIG. 8B in step S34 is displayed, the transmission completion state shown in FIG. 8C when transmission is completed, and the retry determination step S35 in FIG. 8D. This is a case of notifying the timeout shown in FIG. Therefore, in other cases, the control unit 41 performs control to turn off the backlight after a lapse of a certain time, so that it is possible to save power compared to when data is transmitted in the open state of the mobile phone 1. .

  Therefore, the cellular phone 1 according to the present embodiment can improve operability and power saving, and can improve usability when data is transmitted and received using short-range wireless communication.

  Although only infrared communication has been described as the wireless transmission means for profile information, data can be easily transmitted with the same number of operations using the Bluetooth communication function. The Bluetooth transmission mode can be activated, for example, by long pressing the side key 16a.

  Next, data reception processing using the infrared communication function and the Bluetooth communication function will be described.

  FIG. 9 is a flowchart for explaining a reception process of data transmitted from a counter device such as a mobile phone having an infrared communication function, together with an example of an operation performed by the user, using the mobile phone 1 according to the present embodiment. The received data will be described as sender profile information as an example.

  The cellular phone 1 in the data reception process is all performed in the closed state as shown in FIG. 2, and this data reception process starts from the normal standby state (sleep state). The display on the sub-display 21 is also in the state shown in FIG.

  In step S41, the user presses (short presses) the side key 16b to activate an infrared reception mode for receiving profile information (operation 1). In step S42, the control unit 41 that has received an input by pressing (short pressing) the side key 16b by the user executes an infrared reception mode activation process by the infrared communication unit 47, and the mobile phone 1 is in the infrared reception mode being activated. It becomes a state. At this time, the control unit 41 controls the sub display 21 and displays the state of the infrared reception mode on the sub display 21. FIG. 10A is a display example of the sub-display 21 indicating that the infrared reception mode is being activated.

  In step S43, the infrared communication unit 47 confirms a counter device such as a mobile phone as a connection destination as a transmission source of profile information. If the opposite device as the connection destination is confirmed, the infrared communication unit 47 starts receiving profile information transmitted from the opposite device in step S44. FIG. 10B is a display example of the sub-display 21 that is receiving profile information. After completing the reception of the profile information, the series of processing ends, and the sub-display 21 shifts to a normal standby screen. FIG. 10C shows a display example on the sub-display 21 when the transmission of the profile information is completed.

  On the other hand, in the connection destination confirmation step S43, the processing after the retry determination processing step S45, which is a process in the case where the infrared communication unit 47 cannot confirm the other mobile phone that is the transmission source of the profile information and times out, will be described with reference to FIG. Since it is almost the same as the processing after step S35, detailed description is omitted.

  As a notification means for notifying the user that data such as profile information has been received when profile information is received in the receiving step S44 and the mobile phone 1 is opened next time, FIG. 11 is displayed on the main display 17 by the control unit 41.

  Next, data reception processing by the Bluetooth communication function will be described.

  FIG. 12 is a flowchart illustrating an example of an operation performed by the user, using the mobile phone 1 according to the present embodiment, to receive data transmitted from an opposite device such as a mobile phone having a Bluetooth communication function.

  In step S51, the user presses (holds down) the side key 16b to activate the Bluetooth reception mode for receiving profile information (operation 1). In step S52, the control unit 41 that has received an input by pressing (long pressing) the side key 16b by the user executes a Bluetooth reception mode activation process by the Bluetooth communication unit 48, and the mobile phone 1 is in the Bluetooth reception mode being activated. It becomes a state. FIG. 10D is a display example of the sub-display 21 when the Bluetooth reception mode is activated.

  The processing after the device information receiving step S53 is substantially the same as the processing after the device information receiving step S15 described with reference to FIG. Note that the notification for determining the determination displayed on the sub-display 21 by the control unit 41 in the retry determination step S56 and the determination result input process are substantially the same as the process performed in the retry determination step S35 described in FIG. Detailed explanation is omitted.

  Next, a description will be given of reception processing performed by simultaneously activating the data reception mode by the infrared communication function and the Bluetooth communication function.

  FIG. 13 shows an example of an operation performed by the user using the mobile phone 1 according to the present embodiment to receive data transmitted from an opposing device such as a mobile phone having at least one of an infrared communication function and a Bluetooth communication function. It is a flowchart demonstrated with it. By activating both the infrared communication function and the Bluetooth communication function at the same time, there is no need for the user to select the reception mode even if the sending device is equipped with only one communication function. This is effective in that the reception mode can be easily activated. In addition, when sending and receiving data between a large number of people, in the case of infrared reception, it is possible to support multiple opposing devices with infrared communication function and Bluetooth communication function without separating the activation operation from the case of Bluetooth reception It is effective in.

  In step S61, the user simultaneously presses the side keys 16a and 16b to activate the infrared and Bluetooth reception mode for receiving profile information (operation 1). In step S62, the control unit 41 that has received an input by simultaneous pressing of the side keys 16a and 16b by the user controls the infrared communication unit 47 and the Bluetooth communication unit 48, and the infrared communication unit 47 and the Bluetooth communication unit 48 are in the reception mode. Start up. FIG. 10E is a display example showing that the reception mode is being activated, which is displayed on the sub-display 21 by the control unit 41.

  In step S63, the control unit 41 determines whether an opposing device such as a mobile phone that is a transmission source of profile information transmits profile information using a communication function of infrared communication or Bluetooth communication. The determination of the communication function of the opposite device in step S63 is performed by the same process as the connection destination confirmation step S43 described in FIG. 9 when the opposite device uses infrared communication. When the connection destination as the transmission source is confirmed, the process proceeds to the reception step S44 in FIG. When the opposite device uses Bluetooth communication, the determination is performed by the same processing as the device information reception step S53 described with reference to FIG. When the device information of the connection destination that is the transmission source can be received, the process proceeds to the reception step S54 in FIG.

  On the other hand, when the communication function of the connection destination that is the transmission source cannot be confirmed, the process proceeds to the retry determination step S64. Since the processing subsequent to the retry determination step S64 is the same as the retry determination step S35 in FIG.

  According to the cellular phone 1, the four operations that were necessary to activate the reception mode in the past are the side key pressing steps S31, S41, S51, and S61 described with reference to FIGS. Since only a single key press is required, the operability for starting the reception mode can be improved. For this reason, even when transmitting and receiving a self profile that is frequently used, it can be executed with a simple operation, so that user stress can be reduced and the elder layer can be executed without any complicated operation.

  In addition, since the data can be transmitted while the cellular phone 1 is in the closed state, the reception mode state can be displayed only on the sub display 21 without using the main display 17. As a result, an increase in power consumption due to the backlight of the main display 17 with high power consumption can be suppressed, and power saving of the mobile phone 1 can be achieved.

  Specifically, since the mobile phone 1 is closed and data is received, only the sub display 21 needs to be displayed to the user, and it is not necessary to use the main display 17 with high power consumption. As a result, the battery life of the mobile phone 1 can be improved.

  Note that the sub display 21 functions as a display unit and the backlight is turned on, taking the infrared reception mode described with reference to FIG. 9 as an example. During reception mode activation step S42 in reception mode activation shown in FIG. In the data reception step S44, in the reception state shown in FIG. 10B, in the reception completion state shown in FIG. This is a case of notifying the timeout shown in FIG. 8D in the determination step S45.

  Therefore, in other cases, the control unit 41 performs control to turn off the backlight after a lapse of a certain period of time, so that it is possible to save power compared to data transmission / reception in the open state of the mobile phone 1. .

  Therefore, the cellular phone 1 according to the present embodiment can improve operability and power saving, and can improve usability when data is transmitted and received using short-range wireless communication.
