  The light emitting diodes 7a to 7f are respectively connected in parallel between the power source and the transistor 8, and the transistor 8 is controlled by the microcomputer 9 to turn on or off all the light emitting diodes 7a to 7f. Further, the microcomputer 9 performs a driving process for the transistor 8.

  Hereinafter, the driving process of the transistor 8 in the microcomputer 9 will be described with reference to the flowchart shown in FIG.

  First, the state of the mobile phone is read from the memory of the microcomputer 9 (step 100), and it is determined whether it is “standby” (step 110). If it is not “standby”, it is determined NO and step 120 is performed. Proceed to In step 120, it is determined whether or not 10 seconds have elapsed since the end of key operation. If 10 seconds have not elapsed since the end of key operation, NO is determined and the process proceeds to step 130.

The touch sensor 40 detects a touch operation by the user when both of the sensor elements 41 and 42 are touched by the user.

  Next, the electric circuit configuration of the mobile phone will be described with reference to FIG. FIG. 2 is a block diagram showing a schematic configuration of the mobile phone. As shown in FIG. 2, the mobile phone includes a microphone 50, a receiver 51, an audio circuit 52, a radio unit 53, an antenna 54, a storage unit (memory) 55, a display illumination unit 56, an operation illumination unit 57, a secondary battery 58, And a microcomputer 59. The microphone 50 converts the user's voice into a transmission voice signal and outputs it to the voice circuit 52, and the receiver 51 outputs a reception voice from the other party based on the reception voice signal from the voice circuit 52.

  The audio circuit 52 converts the demodulated signal from the radio unit 53 into a received audio signal and outputs it from the receiver 51, while converting the transmitted audio signal from the microphone 50 into a transmission signal and outputs it to the radio unit 53. The radio unit 53 converts the received signal received from the base station via the antenna 54 into a demodulated signal and outputs the demodulated signal to the audio circuit 52, while modulating the transmission signal from the audio circuit 52 and the modulated signal via the antenna 54. To the base station. The storage unit 55 holds various data and computer programs.

  The display illumination unit 56 is controlled by the microcomputer 59 to illuminate the liquid crystal panel 30, and the operation illumination unit 57 is controlled by the microcomputer 59 to illuminate the key operation unit 20. The secondary battery 58 supplies power to the audio circuit 52, the radio unit 53, the storage unit (memory) 55, the display illumination unit 56, the operation illumination unit 57, the microcomputer 59, and the like. The microcomputer 59 performs incoming / outgoing call processing, Internet function, karaoke function processing, backlight processing, and the like.

  Here, the backlight process is performed as an interrupt process at predetermined intervals during execution of the Internet function process. Hereinafter, backlight processing in the microcomputer 59 will be described. The microcomputer 59 performs backlight processing according to the flowchart shown in FIG. First, it is determined whether or not the operation to the key operation unit 20 has been performed (step 200). When the operation to the key operation unit 20 has been performed, the process proceeds to step 210 to display the display illumination unit 56 and the operation illumination unit. 57 is driven. For this reason, the display illumination unit 56 starts illumination of the liquid crystal panel 30, and the operation illumination unit 57 starts illumination of the key operation unit 20.

  Next, it is determined whether or not a certain period has elapsed since the start of illumination of the liquid crystal panel 30 and the key operation unit 20 (step 220), and a certain period after the illumination of the liquid crystal panel 30 and the key operation unit 20 is started. When the time has elapsed, the routine proceeds to step 230, where it is determined whether or not the display on the liquid crystal panel 30 has changed. Here, when the display change flag of the liquid crystal panel 30 (hereinafter referred to as a display change flag) is set in the storage unit 55, it is determined that the display by the liquid crystal panel 30 has changed, and in step 240, the operation is performed. Illumination of the key operation unit 20 by the illumination unit 57 is stopped.

  Next, it is determined whether or not the display change by the liquid crystal panel 30 has ended (step 250). When the display change flag in the storage unit 55 is reset, it is determined that the display change by the liquid crystal panel 30 has ended. In step 260, the illumination of the liquid crystal panel 30 by the display illumination unit 56 is stopped after a certain period.

  Next, it is determined whether or not the touch sensor 40 has been touched (step 270). When the touch sensor 40 has been touched, the process proceeds to step 210. As a result, the display illumination unit 56 and the operation illumination unit 57 are driven as described above. Therefore, the display illumination unit 56 starts illumination of the liquid crystal panel 30 and the operation illumination unit 57 starts illumination of the key operation unit 20.

  Next, in step 270, when the touch sensor 40 is not touch-operated, it progresses to step 280 and it is determined whether the key operation part 20 was operated. Here, when the key operation unit 20 is operated, the process proceeds to Step 210. For this reason, similarly to the above, illumination of the liquid crystal panel 30 is started by the display illumination unit 56 and illumination of the key operation unit 20 is started by the operation illumination unit 57. When the key operation unit 20 is not operated in step 280, the process proceeds to step 270.

  Hereinafter, “browsing news” will be taken up as Internet function processing, and lighting of the liquid crystal panel 30 and the key operation unit 20 from information reception processing (downloading) for news browsing to menu display processing of news will be described with reference to FIG. Will be described with reference to FIG.

  First, when a predetermined operation is performed on the key operation unit 20 in a power-on state, reception of news data information starts from the server side (base station). During information reception, the liquid crystal panel 30 alternately displays the screen shown in FIG. 4A and the screen shown in FIG. 4B. That is, the character 30a changes and the display change flag in the storage unit 55 is set. Here, the liquid crystal panel 30 is illuminated and the key operation unit 20 is illuminated. The processing for displaying the screens shown in FIGS. 4A and 4B by the liquid crystal panel 30 is held in the storage unit (memory) 55 as Internet function processing.

  Next, when a certain period of time has passed and information reception is continuing, as shown in FIGS. 4C and 4D, if the character 30a is changing, the liquid crystal panel 30 is Although illuminated, the illumination of the key operation unit 20 stops.

  Next, when the information reception is completed, the liquid crystal panel 30 displays a news menu as shown in FIG. Here, since the change of the character 30a by the liquid crystal panel 30 is finished and the display change flag is reset, the illumination of the liquid crystal panel 30 is stopped after a certain period of time in addition to the stop of the illumination of the key operation unit 20. . Thereafter, when the touch sensor 40 is touched by the user, the liquid crystal panel 30 is illuminated and the key operation unit 20 is illuminated as shown in FIG.

  Thus, there is no need to operate the key operation unit 20 when receiving information for “browsing news”. For this reason, the liquid crystal panel 30 and the key operation unit 20 are illuminated from the start of information reception until a certain period, but after the certain period, the illumination of the liquid crystal panel 30 is maintained until the change of the character 30a is completed. On the other hand, the illumination of the key operation unit 20 is stopped. Thus, since the illumination of the key operation part 20 is stopped, the power consumption for illumination can be reduced.

  Here, when information reception is performed over a long period of time, power consumption for illumination can be effectively reduced. In particular, when a color liquid crystal panel is adopted as the liquid crystal panel 30, excessive power is consumed. Therefore, in order to reduce power consumption, as described above, the illumination of the key operation unit 20 is stopped according to the change of the character 30a. Is preferred. In addition, when a certain period of time has passed after the end of the change of the character 30a, the illumination of the liquid crystal panel 30 is stopped in addition to the stop of the illumination of the key operation unit 20, so that the power consumption for the illumination is further increased. Can be reduced.

  Further, as disclosed in Japanese Patent Application Laid-Open No. 11-154900, although there are things that can be set in advance to prohibit illumination of one of the liquid crystal panel and the key operation unit, for example, if illumination of the key operation unit is prohibited in advance, When the surroundings are dark, the operability is deteriorated. On the other hand, in the first embodiment, as described above, after the illumination of both the key operation unit 20 and the liquid crystal panel 30 is stopped, the touch operation to the touch sensor 40 or the key operation unit 20 is applied. When the operation is performed, illumination of both the key operation unit 20 and the liquid crystal panel 30 is started, so that favorable operability in the mobile phone can be ensured.

  In carrying out the present invention, during the reception of information, the lighting of both the key operation unit 20 and the liquid crystal panel 30 is controlled in accordance with the change in display by the liquid crystal panel 30 (change in the character 30a). Not limited to this, after the information is received, the display (for example, characters and pictures) on the liquid crystal panel 30 is changed according to the received information from the server side, and the key operation unit 20 and the liquid crystal panel 30 are changed according to the change in the display. You may make it control both illuminations.

  In carrying out the present invention, the mobile phone has processing for changing the display in advance regardless of the Internet function processing, and illumination of both the key operation unit 20 and the liquid crystal panel 30 according to this display change. You may make it perform control of.

  In implementing the present invention, during the download (information reception), the liquid crystal panel 30 (display unit) may be illuminated and the illumination of the key operation unit 20 may be stopped.

  Further, in the first embodiment, the example in which the change (that is, the moving image) of the character 30a is applied as the display change of the liquid crystal panel 30 (display unit) has been described. However, the display change is not limited to this. It may be adopted.

  In the second embodiment, the microcomputer 59 performs a karaoke function process according to the flowchart shown in FIG. First, during standby, a song as karaoke music is selected in response to a predetermined operation on the key operation unit 20, and the karaoke function is started.

  Next, in step 300, the karaoke flag KA is set (KA = 1), karaoke music data is read from the storage unit 55 (step 310), and the voice circuit 52 is driven based on the music data of the karaoke music data. Therefore, the audio circuit 52 outputs karaoke music from the receiver 51. Accordingly, the liquid crystal panel 30 is driven based on the lyrics data of the karaoke music data (step 330). Thereby, the liquid crystal panel 30 displays lyrics according to the output of karaoke music.

  Next, it is determined whether or not the song as karaoke music has ended (step 340). When the song as karaoke music has not ended, the process proceeds to step 310. In step 340, when the song as karaoke music is completed, the process proceeds to step 350 to reset the karaoke flag KA (KA = 0).

  First, in step 210, the display illumination unit 56 starts illumination of the liquid crystal panel 30, and the operation illumination unit 57 starts illumination of the key operation unit 20. Then, it is determined whether or not a certain period has elapsed since the start of illumination of the liquid crystal panel 30 and the key operation unit 20 (step 220), and a certain period of time has elapsed since the illumination of the liquid crystal panel 30 and the key operation unit 20 was initiated. When it does, it progresses to step 221 and the drive of the operation illumination part 57 is stopped. For this reason, the illumination of the key operation unit 20 by the operation illumination unit 57 is stopped. For example, after the lyric data is displayed on the liquid crystal panel 30, the driving of the operation illumination unit 57 is stopped after a certain period.

  Next, it is determined whether or not the song as karaoke music has ended according to the state of the karaoke flag KA (step 223). When the karaoke flag KA is set, the song as karaoke music has ended. If not, the process proceeds to step 224.

  Next, it is determined whether or not the touch sensor 40 has been touched (step 224). When the touch operation has been performed, the process proceeds to step 210, and illumination of the liquid crystal panel 30 is started by the display lighting unit 56 as described above. At the same time, the operation illumination unit 57 starts illumination of the key operation unit 20.

  Next, in step 224, when the touch sensor 40 is not touch-operated, it progresses to step 225 and it is determined whether the key operation part 20 was operated. Here, when the key operation unit 20 is operated, the process proceeds to Step 210. When the key operation unit 20 is not operated in step 225, the process proceeds to step 223.

  As described above, while the karaoke function is being executed, the liquid crystal panel 30 and the key operation unit 20 are illuminated from the start of the karaoke function until a certain period of time. While the illumination of 30 is maintained, the illumination of the key operation unit 20 is stopped. Thus, since the liquid crystal panel 30 is illuminated in a state where the lyrics are displayed by the liquid crystal panel 30, it is possible to reduce power consumption for illumination while ensuring the visibility of the lyrics display.

  In addition, after the illumination of both the key operation unit 20 and the liquid crystal panel 30 is stopped, the touch operation on the touch sensor 40 or the operation on the key operation unit 20 is performed as in the first embodiment.
