  FIG. 3 is an internal block diagram of the mobile phone 1 of the present embodiment. The main internal components of the cellular phone 1 are composed of a CPU 610, a storage means 620, an LED control means 630 as an illumination control means, an input interface 640, an LCD control means 650, a communication means 660, and an audio control means 670. A three-color LED 480 is connected to the LED control means 630, an operation input key 40 is connected to the input interface 640, a liquid crystal unit 50 is connected to the LCD control means 650, an antenna 661 is connected to the communication means 660, A speaker 671 and a microphone 672 are connected to the sound control means 670, respectively. Further, a sensor 70 for detecting opening and closing of the upper body 10 and the lower body 20 is connected to the internal bus of the mobile phone 1.

  The CPU 610 controls functions and operations of each unit of the mobile phone 1, and includes a control unit 611 and an event detection unit 612. The event detection unit 612 monitors the occurrence of a predetermined event in the mobile phone 1, and notifies the control unit 611 when an event is detected. The event detected in this embodiment is the opening / closing of the upper body 10 and the lower body 20 detected by the sensor 70.

  The storage unit 620 includes a ROM or a RAM, and includes an LED pattern registration unit 621 as a lighting pattern registration unit. The LED pattern registration unit 621 stores a lighting pattern for turning on the three-color LED 480 for each event when the event detection unit 612 detects various events. The lighting pattern is formed by data composed of lighting modes of a plurality of three-color LEDs 480 including lighting order, lighting timing for each LED, color, luminance, lighting time, and the like.

  The LED control unit 630 is substantially composed of an LED driving IC or the like, and an LED corresponding to a predetermined event stored in the LED pattern registration unit 621 based on the lighting instruction of the three-color LED 480 from the control unit 611. The three-color LED 480 is turned on according to the lighting pattern. This LED driving IC adjusts the color and brightness of the LED by PWM control.

  The input interface 640 is for converting an input signal generated at the operation input key 40 and transmitting it to the control means 611.

  The LCD control means 650 is composed of an LCD driving IC or the like, and converts data to be displayed on the liquid crystal unit 50 and drives the liquid crystal unit 50 to display an image.

  The sensor 70 includes a magnetic sensor including a hall sensor and a magnet. The upper body 10 is provided with a hall sensor, and the lower body 20 is provided with a magnet. When the cellular phone 1 is folded, the hall sensor is used. The magnetism is detected by approaching the magnet, and when the mobile phone 1 is opened, it is detected that the magnetism in the Hall sensor is weakened. In addition, you may detect opening / closing of the mobile telephone 1 by methods other than a magnetic sensor. The sensor 70 not only detects the opening / closing of the mobile phone 1 but also employs a gravity sensor, detects the orientation of the mobile phone, and opens when the mobile phone is opened in the horizontal direction and in the vertical direction. Depending on each case, the event detection means 612 and the LED control means 630 may light the three-color LEDs 480 in different patterns.

  The communication unit 660 modulates the data of the mail created by the mobile phone 1 and the signal obtained by converting the voice received from the microphone 672 described later in the voice control unit 670 into a radio frequency, and transmits the modulated signal through the antenna 661. . In addition, the radio wave received by the antenna 661 is demodulated and converted into data usable in the mobile phone, or converted into an audio signal via the audio control means 670 and uttered from the speaker 671. The voice control means 670 is composed of a voice codec or the like, and performs coding and decoding of a voice signal.

  Next, the lighting control of the three-color LED in this embodiment will be described with reference to FIG. FIG. 4 is a flowchart of the lighting control of the three-color LED in the embodiment.

  In step S800, the event detection unit 612 of the CPU 610 monitors the occurrence of an event in the mobile phone 1. For example, when the sensor 70 detects that the upper body 10 and the lower body 20 that have been folded so far are opened (flip open), the event detection unit 612 recognizes this event and notifies the control unit 611 of the event. Notify that. In step S810, the control unit 611 calls the LED lighting pattern corresponding to the event from the LED pattern registration unit 621 of the storage unit 620. Next, in step S820, the LED control unit 630 turns on the three-color LED 480 in accordance with the called LED lighting pattern.

  As the lighting pattern, for example, when the upper main body 10 and the lower main body 20 are opened, the three-color LED 480 lights up in turn from the upper left key of the number / character input key 41 toward the lower right key. Light up so that the color changes, and display the light wave. FIG. 5A shows a state in which the mobile phone 1 is folded. FIGS. 5B and 5C show that the mobile phone 1 is opened and the three-color LED 480 has the predetermined lighting pattern described above. It is a figure which shows the state which has lighted. In FIG. 5 (b), the key near the upper left of the number / character input key 41 is brightly lit, and the lit portion moves to the lower right key with time. In FIG. 5 (c), the number / character The key near the lower right of the input key 41 is lit brightly.

  Further, when the sensor 70 is provided with a gravity sensor in addition to the magnetic sensor, the case where the cellular phone 1 is opened while being held in the horizontal direction is distinguished from the case where the cellular phone 1 is opened while being held in the vertical direction. Alternatively, the three-color LED 480 may be turned on by calling a different lighting pattern for each event.

  In the above embodiment, the event occurs when it is detected that the upper main body 10 and the lower main body 20 of the mobile phone 1 are opened. Further, as an event, an incoming mail, incoming call, time signal An alarm or the like may be set. Also, the lighting pattern corresponding to the event is not limited to the example of FIG. 5, but the three-color LED 480 corresponding to the key is lit in a pattern or a checkered pattern that is sequentially lit in the vertical direction or the horizontal direction. Various lighting patterns such as patterns can be registered.

  Furthermore, the occurrence of an event may be detected when the sensor 70 detects that the mobile phone 1 is folded by closing the upper main body 10 and the lower main body 20. In this case, the LED pattern registration unit 621 stores that all LEDs are extinguished as LED lighting patterns.

  The LED lighting pattern registered in the LED pattern registration unit 621 is registered in advance for each event, and when the event is detected, the lighting pattern corresponding to the predetermined event is called to turn on the three-color LED 480. A three-color LED 480 may be lit with a desired lighting pattern by creating or editing a lighting pattern corresponding to the event. In this way, the user can customize lighting of the three-color LED 480 individually.
