The illumination 32 is controlled to be turned on and off by the control unit 12 when a key is pressed or an incoming call is received, and when lit, the key operation unit 24 and the LCD display unit 22 are brightly illuminated. The vibrator 34 is connected to the control unit 12, and the control unit 12
Under the control of, it vibrates at the time of an incoming call etc. to notify it. The ringer or speaker 36 is controlled by the control unit 12 and sounds at the time of an incoming call or the like to notify it. The incoming LED (incoming light emitting diode) 38 is connected to the control unit 12 and, under the control of the control unit 12, blinks at the time of an incoming call or the like to notify it. The incoming LED 38 is provided at the upper end of the front of the mobile communication terminal as shown in FIG. 3, and the speaker 28 is provided on the front of the terminal below the mobile communication terminal, and the LDC display unit 22 is provided on the front of the terminal therebelow.

In the mobile communication terminal as described above,
The incoming call operation is performed as shown in the flowchart of FIG. First, when there is an incoming call in step S11, an incoming call notification is performed by blinking the incoming call LED 38 or the like (step S11).
12) When the call is answered (step S13), the telephone is set to the call state (step S14). On the other hand, if the other party performs a disconnection operation (step S15) without responding to the incoming call, an incoming call history display as shown in FIG. 9 is displayed on the LCD display unit 22 (step S16), and at the same time, the incoming call LED 38 flashes and the incoming call history is displayed. Notification of the display is performed (step S1).
7). Then, the user notices the blinking of the incoming call LED 38 and the like, and confirms the incoming call history display on the LCD display unit 22,
When the key operation of “confirmed” is performed by the key operation unit 24 (step S18), the LCD display unit 22 returns to the standby screen, and the notification of the presence of the incoming call history display by the incoming LED 38 ends (turns off) (step S19). ).

As described above, the incoming call LED 38 blinks both at the time of an incoming call and at the time of informing that there is an incoming call history display. However, since the blinking cycle of the incoming LED 38 is different in both cases, it is possible to distinguish between the incoming call and the notification with the incoming call history display. FIG. 4 is a waveform diagram showing the blinking operation of the incoming call LED 38. At the time of incoming call (FIG. 4 (c)), the intermittent lighting cycle is short and blinks at a short cycle. In (b)), the intermittent lighting cycle is long, and blinks in a long cycle. Incoming LE at the time of notification with incoming call history display
The lighting operation of D38 is performed by the CPU during intermittent reception during standby.
It is performed in synchronization with the intermittent operation (FIG. 4A). Therefore, as described above, the notification of the incoming call history display is sent to the incoming LE.
Even if D38 is blinked, the operation time of the CPU that controls the incoming LED 38 does not become longer than the operation time of the CPU during normal standby, and it is possible to prevent an increase in the current consumption of the CPU.

As described above, in the above embodiment, the incoming call LED 38 is blinked to notify that there is an incoming call history display. In the case of a mobile communication terminal having a folding structure, the incoming call LED 38 can be confirmed to blink even when the terminal is folded, and it is not necessary to open the terminal for confirmation. Furthermore, while the LCD display section can only be seen from the front, the incoming LED 38 has a wide visible range, so even if it is put in the breast pocket, you can see the blinking from the top, and set it on the charger. Can be understood at a glance. Further, in the case of the LCD display unit, it is necessary to turn on the illumination 32 (backlight) in order to see the display at night, but in the case of the incoming call LED 38, this is not necessary. Therefore, according to the above-described embodiment in which the incoming call history is displayed by blinking the incoming call LED 38,
It is easy to notice the presence of the incoming call history display, and it is possible to prevent the occurrence of a failure such as urgent use or leaving an important message for a long time. In addition, when the incoming LED 38 is used, it is not necessary to newly add a component, which is preferable in terms of reducing the size and weight of the mobile communication terminal. In addition, incoming LE
D38 intermittent lighting, as described above, the CPU in standby
By synchronizing with the intermittent operation, the operation time of the CPU does not become longer than the operation time of the CPU at the time of normal standby, so that an increase in current consumption of the CPU can be prevented. Therefore, the standby time can be prolonged by reducing the consumption of the battery.

In the above embodiment, the incoming LED
The incoming / outgoing call notification is distinguished between incoming and outgoing calls with the incoming call history display by changing the blinking cycle of 38. And the type of the incoming call from which group or from which person).

FIG. 5 shows a second embodiment of the present invention. In this case, a dedicated LED 40 is provided at the upper end of the rear surface of the mobile communication terminal, in addition to the incoming LED, for informing that there is an incoming call history display. Here, a color LED that can generate a plurality of colors can be used as the dedicated LED 40. In that case, the type of the incoming call history can be distinguished by the generated color. For example, in connection with the registered contents of the telephone directory, for example, when "green", the call history from group 1 is displayed, when "red", the call history from group 2 is received, and when "orange", friend 1 is displayed.
May represent the history of incoming calls from

FIG. 6 shows a third embodiment of the present invention. In this case, a plurality of LEDs (in this example, reference numerals 411 to 4) are provided on the upper portion of the back of the mobile communication terminal for informing that there is an incoming call history display.
14 (four of fourteen). In this case, each of the plurality of dedicated LEDs 411 to 414 is associated with the type of incoming call history in a one-to-one relationship. For example, the first LED 411 is an incoming call history from group 1 in the telephone directory, and the second LED 412 is an incoming call history from group 2 , The third LED 413 may represent the history of incoming calls from group 3, the fourth LED 414 may represent the history of incoming calls from friend 1, and so on. Note that, as the plurality of LEDs, a seven-segment day character LED or the like can be used.

The embodiment has been described in detail. In the above embodiment, the presence of the incoming call history display is notified by light using the LED. However, a sound (ringing) or the like can be obtained by using the incoming ringer or speaker 36 or the vibrator 34 shown in FIG. The presence of the incoming call history display can also be notified by vibration. Also in this case, similarly to the case of the LED, the ringing or vibration period can be changed to distinguish between the incoming call and the notification of the incoming call history display, and further, the type of the incoming call history can be distinguished. In the case of ringing and vibration, the current consumption of the battery is large. Therefore, it is preferable to set the maximum number of operations outside the operation cycle as shown in the waveform diagram of FIG. In FIG. 7, when the sound or the vibration is performed twice, the notification based on the sound or the vibration is finished. Further, as in the case of the LED, it is preferable that the sound and vibration are performed in synchronization with the intermittent operation of the CPU at the time of standby.
As a result, the current consumption of the battery can be reduced and the standby time can be prolonged.

In addition, as an incoming call, an incoming mail or an incoming call is generally used, but recently, music and news are distributed from a telephone company or an information providing company. Therefore, in this specification, the term “incoming call” includes all incoming mails, incoming calls for calls, the above-mentioned distribution, and other similar information reception. In addition, in this specification, the type of the reception history indicates whether the reception was a mail reception,
It includes both the type of incoming call for a call, the distribution, and other types of reception, and the type of incoming call from which group or from which person in connection with the telephone directory registration.
