Description

  The present invention relates to a portable terminal device capable of transmitting data and a light source control program used for the portable terminal device, and more particularly to a portable terminal device capable of transmitting data provided with a light source in a display unit or an operation unit, and the portable terminal device. The present invention relates to a light source control program used.

  Most portable terminal devices such as mobile phones, notebook personal computers, and PDAs (Personal Digital Assistants) have an e-mail transmission function. In recent years, an e-mail transmission / reception function capable of exchanging e-mails with other mobile phones, personal computers, PDAs, and the like has become essential for mobile terminal devices such as mobile phones and PDAs.

  Generally, these portable terminal devices have a display unit and an operation unit. In order not to impair the visibility of the display unit and the operation unit even in a dark place, many portable terminal devices have a light source on the back of the display unit or the operation unit. These light sources are controlled by a CPU (Central Processing Unit) of information equipment. When a certain time has elapsed since the user last operated the electronic device, the CPU shifts to the power saving mode and turns off the light source. With such a configuration, the power consumption of the mobile terminal device is reduced.

  However, when long-time processing is performed, for example, when the user cannot perform the next operation within the time when the operation unit is lit when searching for an operation key necessary for the operation desired by the user, Nevertheless, the display unit and the operation unit may be turned off. That is, although the user is operating, there is a problem that the mobile terminal device greatly deteriorates the visibility.

In view of this, Japanese Patent Application Laid-Open No. 11-275202 (Patent Document 1) discloses an electronic device that controls to turn on illumination until a set time elapses after a predetermined instruction is generated. The electronic device determines whether to execute the specific processing mode in which the operation interval of the key switch tends to be long, and determines whether the set time has elapsed when the determination unit determines execution of the specific processing mode. Repeating means. When execution of a specific processing mode is determined, lighting control for a set time is repeated, so that turning off during execution of the specific processing mode can be avoided, and usability can be improved and erroneous operations can be avoided.

  However, in the conventional general mobile terminal device, for example, the e-mail transmission function and the power saving mode function operate separately, and for example, even when the e-mail transmission fails, the power saving mode is set. There has been a problem that the user has not noticed that the e-mail transmission has failed due to the migration. This is because, depending on the radio wave conditions, the time from when the user performs the last operation to the transition to the power saving mode may be shorter than the time until the e-mail transmission operation is completed. is there. Therefore, even when the transmission of the e-mail is successful, it is necessary to turn on the display unit again in order to confirm that the user has successfully transmitted the e-mail.

<Functional configuration>
FIG. 3 is a block diagram illustrating a functional configuration of the mobile phone 100 according to the present embodiment. As shown in FIG. 3, the mobile terminal device includes a display unit 121-1, a first light source 122-1, an operation unit 13-1, a second light source 14-1, and a transmission unit 15-1. , Speaker 51-1, vibration device 23, first extinguishing unit 11-2, first invalidation unit 11-3, determination unit (detection unit) 11-4, and first validation unit 11-5, the blinking part 11-6, and the 2nd light extinction part 11-8.

  Here, the first extinguishing unit 11-2, the first invalidating unit 11-3, the determining unit 11-4, the first enabling unit 11-5, the blinking unit 11-6, The two extinguishing units 11-8 are realized by the control device 11-1. The control device 11-1 is realized by, for example, an arithmetic processing device such as the CPU 11, the display control unit 12, and the communication control unit 15, and a control program for realizing each function included in the control device 11-1. Is. Further, the extinguishing unit 11-2, the first invalidating unit 11-3, the first enabling unit 11-5, the blinking unit 11-6, and the second extinguishing unit 11-8 are light source control. Part 11-7 is configured.

  Hereinafter, various functions of the mobile terminal device will be described. As described above, the functions of the following blocks and processing of each step are realized by software executed on the control device 11-1 realized by the CPU 11 and the like. Alternatively, each may be realized by a dedicated hardware circuit or the like.

  First, the display unit 121-1 is realized by the LCD 121, and displays information such as a calculation result of the CPU 11, for example. The first light source 122-1 is realized by the LCD backlight 122, and illuminates the display unit 121-1, thereby informing the user and the like of the content displayed on the display unit 121-1. The first light source 122-1 is switched on and off in accordance with a command from the light source control unit 11-7 including the first extinguishing unit 11-2 and the blinking unit 11-6. The first light source 122-1 can make the user recognize the content displayed on the display unit 121-1 even in the dark by illuminating the display unit 121-1.

  The operation unit 13-1 is realized by, for example, the operation keys 13, and receives an instruction from the outside. Here, “accept” is a concept including at least an operation for giving data or a signal to the control device 11-1. For example, a command for an external operation by a user or the like is generated to control the control device 11-1. It is a concept that includes the action given to In addition, “accept” means not only an operation in which the control device 11-1 accepts information from a human by an operation key or a voice input, but also a control device that accepts data or signals from other programs or other media. It is a concept including an operation given to 11-1.

  And in this Embodiment, although operation part 13-1 is realized by operation key 13 provided in lower case 56 of cellular phone 100, for example, with a touch panel which realizes display part 121-1. It may be realized. When the operation unit 13-1 is realized by a touch panel, the user may input an instruction using a stylus pen or the like.

  The second light source 14-1 is realized by, for example, a key backlight 14 provided on the back surface of the operation key 13. By illuminating the operation unit 13, a user can access the operation unit 13-1. Make typing easier. When the operation unit 13-1 is realized by a touch panel that realizes the display unit 121-1, the second light source 14-1 may be realized by the first light source 122-1.

  The transmission unit 15-1 is realized by the communication control unit 15, the radio unit 151, and the antenna 152, for example, and transmits data to an external network or the like in response to an instruction from the outside (for example, a user). The transmission unit 15-1 performs transmission / reception of data packets with an external network, for example. Then, from the contents of the received data packet, it is possible to grasp that the electronic mail has been received by the other party or that there is no other party corresponding to the destination address.

  Next, the 1st light extinction part 11-2, the 1st invalidation part 11-3, the judgment part 11-4, the 1st validation part 11-5, the blinking part 11-6, and a light source The control unit 11-7 is realized, for example, by executing a program read from the second memory 18 to the first memory 17 on the CPU 11. That is, the program stored in the second memory 18 is once read to the first memory 17 and the CPU 11 sequentially executes the program while reading the program from the first memory 17. Functions such as are realized.

  In this way, the first light-off unit 11-2 turns off the first light source 122-1 when an instruction from the outside (for example, a user) is not input through the operation unit 13-1 for a first predetermined period. That is, the mode is shifted to the “power saving mode”. Further, the first light-off unit 11-2 turns off the second light source 14-1 when an instruction from the outside is not input through the operation unit 13-1 for the first predetermined period, that is, the “power saving mode” ”. As described above, when the input from the user is not performed for a certain period, the first light source 122-1 and the second light source 14-1 are automatically turned off to reduce power consumption in the portable terminal device. is doing.

  The first invalidation unit 11-3 disables the function of the extinguishing unit 11-2 when the data transmission operation is started, that is, when the transmission unit 15-1 starts the transmission operation such as an e-mail. Turn into. In other words, even when an instruction from the user is not input for the first predetermined period, the first light source 122-1 and the second light source 14-1 are not turned off, for example, during an e-mail transmission operation. Thereby, without the user's operation, the user can grasp whether the transmission operation is being performed or whether the transmission operation has been completed.

  The determination unit 11-4 determines whether or not the data transmission is successful based on the information from the transmission unit 15-1. For example, as described above, from the content of the data packet passed from the transmitting unit 15-1, it is understood that the e-mail has been received by the other party, or that there is no other party corresponding to the destination address. Such a data transmission state can be stored in the first memory 17.

  The first enabling unit 11-5 enables the function of the first extinguishing unit 11-2 again when it is determined that the data transmission is successful. That is, when the determination unit 11-4 determines that the data transmission is successful, the first light source 122 is input when no instruction is input from the user for the first predetermined period by the first extinguishing unit 11-2. -1 is turned off.

  Further, even if it is determined that the data transmission has failed, the first enabling unit 11-5 turns off the light 11-2 when an instruction from the outside is input to the operation unit 13-1. Enable the function. That is, even when the determination unit 11-4 determines that the data transmission has failed, it waits for an input from the user through the operation unit 13-1. And if the input from a user is received through the operation part 13-1, when the instruction | indication from a user is not input for the 1st predetermined period by the 1st light extinction part 11-2, the 1st light source 122-1 will go out. It becomes a state.

  The second extinguishing unit 11-8 extinguishes the second light source 14-1 during the data transmission operation regardless of whether there is an external input. Here, during the data transmission operation, the operation unit 13-1 may be configured not to accept an input from the outside.

  When the determination unit 11-4 determines that data transmission has failed, the blinking unit 11-6 causes the first light source 122-1 to blink until an external instruction is input. That is, when the determination unit 11-4 determines that data transmission has failed, the first light-off unit 11-2 turns off the first light source 122-1 and the second light source 14. Not. At this time, the blinking unit 11-6 causes the first light source to blink 122-1. As a result, the user can be surely notified that the data transmission has failed. The blinking unit 11-6 blinks the second light source 14-1 until an instruction from the outside is input when the determination unit 11-4 determines that data transmission has failed.

  In other words, the determination unit (detection unit) 11-4 detects the data transmission state based on the information from the transmission unit 15-1. Specifically, the determination unit 11-4 detects the e-mail transmission status stored in the CPU 11 or the first memory 17. Specifically, the determination unit 11-4 determines each state of mail transmission success, mail transmission success, and mail transmission failure based on information from the transmission unit 15-1. For example, a portion of the internal register (not shown) of the CPU 11 regarding the mail transmission state is read, and it is detected whether the mobile phone is transmitting mail to the CPU 11 and whether mail transmission is successful or mail transmission failure, and the state is controlled by light source To part 11-7.

  Then, the light source control unit 11-7 turns on, blinks, or turns off the first light source 122-1 and the second light source 14-1 according to the data transmission state. Specifically, the light source controller 11-7 determines at least one of the first light source 122-1 and the second light source 14-1 from the start of data transmission until the data transmission is successful based on the data transmission state. Keep either one lit. Even when the data transmission fails, the light source controller 11-7 cancels the lighting state when an instruction from the outside is input. Further, the light source control unit 11-7 turns off the second light source 14-1 during the data transmission operation. When the data transmission fails, the light source control unit 11-7 blinks the first light source 122-1 until an external instruction is input. In addition, when the data transmission fails, the light source control unit 11-7 blinks the second light source 14-1 until an external instruction is input.

  The speaker 51-1 is realized by at least one of the first speaker 51 and the second speaker 61. When the determination unit 11-4 determines that data transmission has failed, the speaker 51-1 is external. A voice warning is issued until an instruction is input. The voice is preferably a dedicated melody when data transmission fails. The sound from the speaker 51-1 may be output until there is an input from the outside, or may be output for a predetermined time preset by the user.

  When the determination unit 11-4 determines that the data transmission has failed, the vibration device 23 vibrates the mobile terminal device itself until an external instruction is input. The vibration by the vibration device 23 may be output until there is an input from the outside, or may vibrate for a predetermined time set in advance by the user.

<Light source control processing>
Next, processing according to the present embodiment will be described. FIG. 4 is a flowchart showing the flow of light source control processing in mobile phone 100 according to the present embodiment. Hereinafter, as an example of data transmission, a case where electronic mail is transmitted will be described.

  First, the mobile phone 100 is generally configured to shift to a mode in which the LCD backlight 122 and the key backlight 14 are turned off, that is, a power saving mode when there is no input from the user for a certain period of time. The state that can be shifted to the power saving mode is a state in which the first extinguishing unit 11-2 is effective. On the contrary, the state in which the transition to the power saving mode is prohibited is a state in which the first extinguishing unit 11-2 is invalidated.

  As shown in FIG. 4, when the mail software of the mobile phone 100 is activated and the user inputs an address, a subject, and a text using the operation keys 13 and presses the mail transmission key, that is, an e-mail according to a command from the user Is transmitted from the communication control unit 15 (if YES in step 101, the following step is abbreviated as S), the CPU 11 functioning as the first invalidating unit 11-3 activates the light source control program. That is, the CPU 11 instructs the display control unit 12 to prohibit the transition to the power saving mode (S102). Then, the CPU 11 starts acquiring the mail transmission status and determines whether or not the mail transmission status is transmitting an email (S103).

  If the mail transmission status is being transmitted (YES in S103), the CPU 11 repeats the acquisition of the mail transmission status and the determination of whether the mail is being transmitted. When the mail transmission status is not being transmitted (NO in S103), the CPU 11 determines whether or not the mail transmission is normally completed (successful) (S104).

  If the mail transmission status indicates successful transmission (YES in S104), the CPU 11 instructs the display control unit 12 to turn off the display function (S105). Then, the display control unit 12 turns off the LCD 121 and the LCD backlight 122 based on an instruction to turn off the display from the CPU 11, and then cancels the prohibition of transition to the power saving mode (S106). Exit.

  On the other hand, if the mail transmission status is a transmission failure (NO in S104), the CPU 11 instructs the LCD 121 to display a mail transmission failure pop-up display (S107).

  Here, FIG. 5 is an image diagram showing an example of display contents of the display unit 121-1 when the mobile terminal device fails in data transmission. When the determination unit 11-4 determines that the transmission of the e-mail has failed, the display unit 121-1 displays, for example, a screen as shown in FIG. The display unit 121-1 shows a mail transmission failure pop-up display 64, a radio wave reception sensitivity display 61, an external memory status display 62, a battery remaining amount display 63, and the like.

  The mail transmission failure pop-up display 64 is for displaying a dialog box indicating that the mail transmission has failed when the mail transmission fails, and notifies the user of the transmission failure by the display. The radio wave reception sensitivity display 61 is a schematic representation of the surrounding radio field intensity, and the right vertical bar gradually decreases from 3 → 2 → 1 → 0 as the ambient radio field intensity decreases. When the radio wave is completely blocked, “out of service area” is displayed. The external memory status display 62 indicates the insertion / removal status of the external memory. The external memory status display 62 is displayed when an external memory such as an SD card is inserted in the cellular phone, and is not displayed when it is not inserted. The battery remaining amount display 63 schematically represents the remaining amount of the internal battery of the mobile phone. As the remaining amount of the battery decreases, the white portion of the display gradually decreases from 3 → 2 → 1. It becomes zero when the remaining amount is completely exhausted.

  Then, the CPU 11 determines whether or not there is an external input such as the operation key 13 or the peripheral I / F circuit 19 (S108). Then, when there is no input from the outside (NO in S108), the CPU 11 repeats the determination for a predetermined time (S109). The time waiting for input from the outside may be a time that can be set in advance by the user, or may be a time that is predetermined for the mobile phone 100. If an external input is made (YES in S108), the CPU 11 cancels the prohibition of transition to the power saving mode (S106) and ends the light source control program.

  If no external input is made after a certain period of time (YES in S109), a sound is output from the first speaker 51 or the second speaker 61, or the vibration device 23 is vibrated. This prompts the user to resend the e-mail (S110). Thereafter, the process returns to the step of waiting for an external input (S108). The sound output from the first speaker 51 or the second speaker 61 and the vibration of the vibration device 23 may be executed for a predetermined time or until an input from the outside is accepted (YES in S108). It may be a thing.

  Here, in S102, since the CPU 11 instructs the display control unit 12 to prohibit the transition to the power saving mode, if transmission fails (NO in S104), the LCD 121 and the LCD backlight 122 Is always on without being turned off. As a result, it becomes possible to visually confirm that the transmission has failed, so it is possible to prompt the user to resend the mail. Further, when transmission is successful, LCD 121 and LCD backlight 122 are turned off, and when transmission fails, LCD 121 and LCD backlight 122 are turned on. Therefore, the user does not bother to turn on LCD 121 and LCD backlight 122. In both cases, it is possible to know the success of transmission, and it is possible to eliminate the troublesome operation of the mobile phone 100 only for checking the transmission state. The LCD 121 and the LCD backlight 122 can be turned off by shutting off the power supply, executing the sleep mode built in the device, or as long as the off state can be realized. It is.

<Modification 1>
Next, a modified example of the mobile phone 100 will be described. The mobile phone 200 according to the present modification is different from the mobile phone 100 only in the processing procedure in the light source control process. Since the overall configuration, hardware configuration, and functional configuration are the same as those of mobile phone 100 shown in FIGS. 1 to 3, description thereof will not be repeated here.

  Hereinafter, a light source control process in mobile phone 200 according to the present embodiment will be described. FIG. 6 is a flowchart showing a processing procedure of light source control processing in the mobile phone 200 according to the present modification.

  First, the mobile phone 200 is generally configured to shift to a mode in which the LCD backlight 122 and the key backlight 14 are turned off when there is no input from the user for a certain period of time, that is, a power saving mode.

  Then, as shown in FIG. 6, when the user activates the mail software of the mobile phone 200, inputs the address, subject, and text using the operation keys 13 and presses the mail transmission key, that is, according to a command from the user When the e-mail is transmitted from the communication control unit 15 (in the case of YES in step 201, the step is hereinafter abbreviated as S), the CPU 11 functioning as the first invalidation unit 11-3 starts the light source control program. . That is, the CPU 11 instructs the display control unit 12 and the operation key control unit realized by the CPU 11 to prohibit the transition to the power saving mode (S202). Then, the CPU 11 starts acquiring the mail transmission status and determines whether or not the mail transmission status is sending an email (S203).

  When the mail transmission status is being transmitted (YES in S203), the CPU 11 turns off the key backlight 14 (S204). Then, the CPU 11 repeats the acquisition of the mail transmission status and the determination as to whether the mail is being transmitted. When the mail transmission status is not being transmitted (NO in S203), the CPU 11 determines whether or not the mail transmission is normally completed (successful) (S205).

  If the mail transmission status indicates successful transmission (YES in S205), the CPU 11 instructs the display control unit 12 to turn off the display function (S206). Then, the display control unit 12 turns off the LCD 121 and the LCD backlight 122 based on the display off instruction from the CPU 11, then cancels the prohibition of transition to the power saving mode (S 207), and ends the light source control program. To do.

  On the other hand, if the mail transmission status is a transmission failure (NO in S205), the CPU 11 instructs the LCD 121 to display a mail transmission failure pop-up display as shown in FIG. 5 (S208). At the same time, the CPU 11 turns on the key backlight 14 (S209). However, the CPU 11 may be configured to blink the LCD backlight 122-1 and the key backlight 14 in S209.

  Then, the CPU 11 determines whether or not there is an input from the outside such as the operation key 13 or the peripheral I / F circuit 19 (S210). Then, when there is no external input (NO in S210), the CPU 11 repeats the determination for a predetermined time (S211). The time waiting for input from the outside may be a time that can be set in advance by the user, or may be a time that is predetermined for the mobile phone 100. If an external input is made (YES in S210), the CPU 11 cancels the prohibition of transition to the power saving mode (S207) and ends the light source control program.

  If no external input is made after a certain period of time (YES in S211), a melody voice is output from the first speaker 51 or the second speaker 61, or the vibration device 23 is vibrated. This prompts the user to resend the e-mail (S212). Thereafter, the process returns to the step of waiting for an external input (S210). The audio output from the first speaker 51 or the second speaker 61 and the vibration of the vibration device 23 may be executed for a predetermined time or until an input from the outside is accepted (YES in S210). It may be a thing.

  Thus, in this modification, since the key backlight 14 is turned off immediately after the mail transmission operation is started, power consumption can be reduced as compared with the mobile phone 100 according to the first embodiment. As in the first embodiment, when transmission is successful, the LCD 121, the LCD backlight 122, and the key backlight 14 are turned off. When the transmission fails, the LCD 121, the LCD backlight 122, and the key backlight 14 are turned on (flashing), so that the user can easily know whether the transmission of the e-mail has succeeded or failed. As a result, the user is free from the troublesome operation of the mobile phone 100 to confirm the transmission state.

[Embodiment 2]
Next, a second embodiment of the mobile terminal device will be described. Mobile phone 300 according to the present embodiment is different from mobile phone 100 in part of the functional configuration and the processing procedure in the light source control process. Since the overall configuration and the hardware configuration are the same as those of mobile phone 100 shown in FIGS. 1 and 2, description thereof will not be repeated here.

  FIG. 7 is a functional block diagram showing a functional configuration of mobile phone 300 according to the present embodiment. As illustrated in FIG. 7, the mobile terminal device includes a display unit 121-1, a first light source 122-1, an operation unit 13-1, a second light source 14-1, and a transmission unit 15-1. , Speaker 51-1, vibration device 23, first extinguishing unit 11-2, second invalidating unit 11-9, determining unit (detecting unit) 11-4, and second enabling unit 11-10, the blinking part 11-6, and the 2nd light extinction part 11-8. As described above, the mobile phone 300 according to the second embodiment is different from the mobile phone 100 according to the first embodiment in that the second disabling unit 11-9 and the second enabling unit 11-10 Are different.

  As in the first embodiment, the first extinguishing unit 11-2, the second invalidating unit 11-9, the determining unit 11-4, and the second enabling unit 11-10 are blinking. The unit 11-6 and the second extinguishing unit 11-8 are realized by the control device 11-1. Further, the extinguishing unit 11-2, the first invalidating unit 11-9, the first enabling unit 11-10, the second extinguishing unit 11-8, and the blinking unit 11-6 are light source control. Part 11-7 is configured. Hereinafter, although various functions which a portable terminal device has are explained, explanation about a functional block explained in Embodiment 1 is not repeated.

  The second invalidation unit 11-9 and the second validation unit 11-10 are configured such that, for example, a program read from the second memory 18 to the first memory 17 is executed on the CPU 11. It is realized by. That is, the program stored in the second memory 18 is once read to the first memory 17 and the CPU 11 sequentially executes the program while reading the program from the first memory 17. And light source control processing is realized.

  In this way, the second invalidation unit 11-9 invalidates the extinguishing unit 11-2 when it is determined that the transmission of the data by the transmission unit 15-1 has failed. That is, when the transmission of the e-mail fails, the first light source 122-1 and the second light source 14-1 are not turned off even if the instruction from the user is not input for the first predetermined period. . Thereby, without the user's operation, the user can grasp whether the transmission operation is being performed or whether the transmission operation has been completed.

  And the 2nd validation part 11-5 validates the 1st extinguishing part 11-2, if the instruction from the outside is inputted, for example via operation part 13-1. That is, even when the determination unit 11-4 determines that data transmission has failed, the second validation unit 11-5 waits for an input from the user through the operation unit 13-1. And if the input from a user is received through the operation part 13-1, when the instruction | indication from a user is not input for the 1st predetermined period again by the 1st light extinction part 11-2, the 1st light source 122-1 will be. It returns to the state where it goes out.

  Hereinafter, light source control processing in mobile phone 300 according to the present embodiment will be described. FIG. 8 is a flowchart showing a processing procedure of light source control processing in mobile phone 300 according to the present embodiment.

  First, the mobile phone 300 is generally configured to shift to a mode in which the LCD backlight 122 and the key backlight 14 are turned off, that is, a power saving mode when there is no input from the user for a certain period of time.

  Then, as shown in FIG. 8, when the mail software of the mobile phone 300 is activated and the user inputs the destination, subject, and text using the operation keys 13 and presses the mail transmission key, that is, according to a command from the user When the e-mail is transmitted from the communication control unit 15 (in the case of YES in step 301, the step is hereinafter abbreviated as S), the CPU 11 functioning as the second invalidating unit 11-9 activates the light source control program. .

  In this embodiment, at this timing, the CPU 11 is not yet instructed not to prohibit the transition to the power saving mode. In other words, in the present embodiment, since the transition to the power saving mode is not prohibited during the transmission of the e-mail, a predetermined time (a time that can be set by the user, which is about a dozen seconds or more) from the last operation by the user. When the time elapses, the CPU 11 functioning as the first extinguishing unit 11-2 turns off the LCD backlight 122 and the key backlight 14.

  Then, the CPU 11 starts acquiring the mail transmission status and determines whether or not the mail transmission status is transmitting an email (S302). When the mail transmission status is being transmitted (YES in S302), the acquisition of the mail transmission status and the determination as to whether the mail is being transmitted are repeated (S302). Here, similarly to the above-described modification, the CPU 11 may be configured to turn off the key backlight 14 when the mail transmission status is being transmitted (YES in S302). When the mail transmission status is not being transmitted (NO in S302), the CPU 11 determines whether or not the mail transmission is normally completed (successful) (S303).

  If the mail transmission status indicates successful transmission (YES in S303), the CPU 11 instructs the LCD backlight 122 (display control unit 12) and the key backlight 14 to turn off (S304). Then, the display control unit 12 turns off the LCD 121 and the LCD backlight 122 based on the display off instruction from the CPU 11, and then ends the light source control program.

  On the other hand, when the mail transmission status is a transmission failure (NO in S303), the CPU 11 instructs the LCD 121 to display a mail transmission failure pop-up display as shown in FIG. 5 (S305). At the same time, the CPU 11 turns on the LCD backlight 122 and the key backlight 14 (S306).

  Then, the CPU 11 instructs the display control unit 12 and the operation key control unit realized by the CPU 11 to prohibit the transition to the power saving mode (S307). The CPU 11 determines whether or not there is an external input such as the operation key 13 or the peripheral I / F circuit 19 (S308). If there is no input from the outside (NO in S308), the CPU 11 repeats the determination for a predetermined time (S309). The time waiting for input from the outside may be a time that can be set in advance by the user, or may be a time that is predetermined for the mobile phone 100. If an external input is made (YES in S308), the CPU 11 cancels the prohibition of transition to the power saving mode (S310) and ends the light source control program.

  If no external input is made after a certain period of time has elapsed (YES in S309), audio is output from the first speaker 51 or the second speaker 61, or the vibration device 23 is vibrated. This prompts the user to resend the email (S311). Thereafter, the process returns to the step of waiting for an external input (S308). The sound output from the first speaker 51 or the second speaker 61 and the vibration of the vibration device 23 may be executed for a predetermined time or until an input from the outside is accepted (YES in S308). It may be a thing.

  In mobile phone 300 according to the present embodiment, CPU 11 is configured to turn on LCD 121, LCD backlight 122, and key backlight 14 in S306. However, in S306, the CPU 11 may be configured to switch the LCD 121, the LCD backlight 122, and the key backlight 14 on and off at regular intervals to blink. As a result, the visibility with respect to the failure to send the e-mail can be further improved, and the user can be urged to retransmit the mail more efficiently.

  Finally, differences between the mobile phone 300 according to the second embodiment and the mobile phone 100 (200) according to the first embodiment (including modifications) will be described. The difference between the mobile phone 100 according to the first embodiment and the mobile phone 300 according to the second embodiment is the number of instructions executed by the CPU 11 executing the light source control program. In mobile phone 100 according to the first embodiment, a prohibition to shift to the power saving mode is instructed when mail transmission starts, but in the mobile phone 300 according to the second embodiment, a prohibition to shift to the power saving mode is instructed only when transmission fails. To do. Since the number of mail transmission failures is certainly smaller than the number of mail transmissions, the number of command executions for prohibiting the transition to the power saving mode is smaller in the mobile phone 300 according to the second embodiment, and the load on the CPU 11 By reducing, processing can be performed smoothly.

  Next, the difference between the mobile phone 200 according to the modification of the first embodiment and the mobile phone 300 according to the second embodiment is that the mobile phone 300 according to the second embodiment has a smaller number of command executions. The power consumption can be reduced because the LCD 121 and the LCD backlight 122 are turned off even during mail transmission. In the mobile phone 200 according to the modification, the LCD 121 and the LCD backlight 122 are turned on during mail transmission. However, the mobile phone 300 according to the second embodiment can enter the power saving mode except when the mail transmission fails. Therefore, the LCD 121, the LCD backlight 122, and the key backlight 14 are turned off after a predetermined time from the user's last operation. Therefore, mobile phone 300 according to Embodiment 2 can reduce power consumption.

  Although the application example to the foldable mobile phone has been described in the above embodiment, the present invention is not limited to this, and can also be applied to a straight mobile phone and a slide mobile phone. Needless to say, the present invention can be applied not only to mobile phones but also to all electronic devices having a mail transmission function such as PDAs and notebook PCs. Furthermore, in the above embodiment, the present invention is applied to the main display unit of the electronic device. However, in an electronic device having a sub display unit, the present invention can be similarly applied to the sub display unit. Furthermore, in the above-described embodiment, the present invention is applied to a program. However, it is of course possible to implement with a hard logic, and the program of the present invention is stored in an external memory such as a CD-ROM or an SD card. It is also possible.

  Further, in the embodiment of the present invention, the LCD has been described as an example of the display unit. However, the display unit is not limited to EL (Electro Luminescence), CRT (Cathode Ray Tube), PDP (Plasma Display Panel), etc. Anything that can be displayed is applicable. Further, the display unit and the display unit need not be separated from each other, and the display unit itself may emit light. The operation unit has been described by taking a push-down type mechanical key as an example, but any operation unit such as a slide type mechanical key, a touch panel, or an electrostatic touch key can be applied. In addition, the LCD / key backlight has been described using an LED (Light Emitting Diode) as an example, but any other light emitting body such as a fluorescent lamp or a light bulb may be used. Furthermore, an apparatus in which the operation unit itself emits light may be used. Of course, the present invention can also be applied to a device in which the display unit and the operation unit are integrated.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
