FIG. 2 is a flowchart showing the operation of the mobile phone 1 when the display unit 17 is transited to the low power consumption state.

First, when the power is turned on by the user, the CPU section 14 is in a standby state except during a call and an operation, and the timers T1 and T2 of the timer section 31 are turned on (step s201). In this state, the CPU unit 14 confirms whether there is an incoming call (step s202), and if it judges that there is an incoming call, all the timers T1, T of the timer unit 31
2 is turned off (step s209), and the power of the display unit 17 is kept on (step s210).

If it is determined in step s202 that there is no incoming call, the CPU section 14 confirms whether or not there is an operation by the user (step s203). All timers T1,
T2 is turned off (step s209), and the power of the display unit 17 is kept on (step s21).
0).

When it is determined in step s203 that there is no operation by the user, the CPU section 14 determines a predetermined fixed time (T
It is confirmed whether or not 1) has passed (step s20
4) If it is determined that T1 has not elapsed, the operation of confirming the presence or absence of an incoming call (step s202) is repeated.

When it is determined in step s204 that T1 has passed, the CPU section 14 causes the display drive section 16 to transition the display section 17 to the low power consumption state (step s).
205). In the next step s206, it is confirmed whether or not a predetermined second fixed time (T2) has elapsed, and if it is determined that T2 has not elapsed, the operation of confirming the presence or absence of an incoming call (step s202) is repeated.

When it is determined in step s206 that T2 has elapsed, the CPU section 14 operates the vibrating section 15 in an arbitrary specific pattern (step s207), and the display section 17
Informs the user that the is in a low power consumption state. After that, the counter of T2 is initialized (step s208),
The operation of confirming the presence or absence of an incoming call (step s202) is repeated.

In this way, the display unit 17 is transited to the low power consumption state when the first constant time (T1), which is set in advance with no incoming call or user operation with the power turned on, has passed, The user is notified by operating the vibrating section 15 that the state is present. This allows the user to know whether the power of the mobile phone 1 is on or off without directly checking it.

When the user enters a low power consumption state while still in his pocket, and the power is automatically turned off, the power supply is turned off at an early stage by recognizing that the vibrating section 15 is not operating. You can know that it is out.

Further, since the user is informed after the second predetermined time (T2) that the display unit 17 is in the low power consumption state has passed, the user can make the mobile phone 1 in the low power consumption state.

The mobile phone according to the present embodiment has a detector that detects a folded state. Other than that, the configuration is the same as that of the mobile phone 1 of FIG.

First, when the power is turned on by the user, the CPU section 14 is in a standby state except during a call and an operation, and the timers T1 and T2 of the timer section 31 are turned on (step s301). In this state, the CPU unit 14 confirms through the detector whether or not the flipper of the mobile phone is open (step s302). If it is determined that the flipper is open, the CPU 14 confirms whether or not there is an incoming call (step s304) and opens it. When it is determined that the timer has not been turned on, the timer T3 is turned on. When it is determined that there is an incoming call in step s304, the timer unit 31
All the timers T1, T2, T3 are turned off (step s311), and the power of the display unit 17 is kept on (step s312).

When it is determined in step s304 that there is no incoming call, the CPU section 14 confirms whether or not there is an operation by the user (step s305). All timers T1,
Turn off T2 and T3 (step s311), and display unit 1
The power of 7 is kept on (step s3
12).

When it is determined in step s305 that there is no operation by the user, the CPU section 14 determines a first fixed time (T
It is confirmed whether or not 1) has passed (step s30
6) If it is determined that T1 has not elapsed, the open / close state of the flipper is confirmed (step s302).

When it is determined in step s306 that T1 has elapsed, the CPU section 14 causes the display section 17 to transition to the low power consumption state via the display drive section 16 (step s).

On the other hand, when it is determined in step s302 that the flipper is closed, that is, folded, the timer T3 is turned on as described above. The CPU unit 14 confirms whether or not a predetermined third predetermined time (T3) has elapsed after detecting the folded state (step s3).
03), if it is determined that T3 has not passed, the open / closed state of the flipper is confirmed (step s302).

When it is determined in step s303 that T3 has elapsed, the CPU section 14 causes the display section 17 to transition to the low power consumption state via the display drive section 16 (step s).
307).

After step s307, the CPU unit 14
Confirms whether or not a predetermined second fixed time (T2) has elapsed (step s308), and when it is determined that T2 has not elapsed, the confirmation of the open / closed state of the flipper (step s302) is repeated.

When it is determined that T2 has passed in step s308, the CPU section 14 operates the vibrating section 15 in an arbitrary specific pattern (step s309), and the display section 17
Informs the user that the is in a low power consumption state. After that, the counter of T2 is initialized (step s310),
The confirmation of the open / closed state of the flipper (step s302) is repeated.

As described above, in the case of the folding clamshell type, the display unit 17 is transited to the low power consumption state when a predetermined time (T3) has elapsed after detecting the folded state, Notify me. As a result, even in the case of the clamshell type, the user can know that it is in the low power consumption state without looking at the sub display unit.
Further, when folded, the steps (s304, s305) for confirming whether there is an incoming call or an operation by the user can be omitted, and the state can be effectively shifted to the low power consumption state.

In the embodiment shown in FIGS. 2 and 3, only the vibrating section 15 is used as the informing means for informing the low power consumption state. However, the audio section 19 can be operated instead of the vibrating section 15, and the vibration is generated. It is also possible to operate the section 15 and the voice section 19 in combination. The notification pattern of the low power consumption state includes the combination of the vibrating unit 15 and the voice unit 19,
It can be arbitrarily set by the user. This allows the user to easily distinguish between the notification of the low power consumption state and the incoming call.

The fixed times T1, T2 and T3 predetermined in the embodiments of FIGS. 2 and 3 can be arbitrarily set by the user. With this, it is possible to arbitrarily set the time until the low power consumption state is set according to the individual usage state of the user.

In the embodiment shown in FIGS. 2 and 3, the predetermined fixed times T1, T2 and T3 are clocked by the timer section 31, but not limited to this, the second fixed time (T2) is linked with the RTC section 30. It is also possible to set the time unit of the clock. As a result, since the notification of the low power consumption state can be performed just every hour or every 30 minutes, the current time can be notified at the same time as the notification of the low power consumption state.

[0045]

As described above, according to the present invention, even when the display system of the portable radio communication device is in a pocket or the like in a low power consumption state, it can be used by operating the vibrating section and the voice section. The person can know whether the power of the portable wireless communication device is on or off without directly checking it. As a result, it is possible to reduce the possibility of turning on the power where it has to be turned off.

When the user enters a low power consumption state while still in his pocket, and when the power is automatically turned off, it is possible to recognize an early stage by recognizing that the vibrating section and the voice section are not operating. You can know that the power is off.
