[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration of a mobile phone according to an embodiment of the present invention. 1, a mobile phone 1 according to an embodiment of the present invention includes an antenna 10, a transmission unit 11, a reception unit 12, an operation key unit 13, a vibration sensor 14, a control unit 15, a memory 16, and a timer. 17, a power supply control unit 18, a display control unit 19, a display unit 20, a transmitter 21, and a receiver 22.
[0016]
The transmission unit 11 transmits various signals such as a dial signal from the control unit 15 and a transmission signal from the transmitter 21 via the antenna 10. The receiving unit 12 sends the call signal received via the antenna 10 to the control unit 15 and sends the received signal to the receiver 22. The operation key unit 13 is used by the user to input a dial number and the like.
[0017]
The vibration sensor 14 detects vibration applied to the mobile phone and sends an electric signal corresponding to the vibration to the control unit 15. The control unit 15 controls each unit by executing a program recorded in the memory 16. Further, when the operation mode of the mobile phone 1 is in the power saving mode (power saving mode), the control unit 15 cancels the power saving mode according to the vibration detected by the vibration sensor 14 and sets the operation mode to the normal mode.
[0018]
That is, the control unit 15 cancels the power saving mode when the vibration detected by the vibration sensor 14 has a predetermined characteristic when the operation mode is the power saving mode. Here, the program executed by the control unit 15 and the telephone number of the other party are recorded in the memory 16, and a predetermined vibration pattern to be compared with the vibration pattern detected by the vibration sensor 14 is recorded in advance. Has been. The predetermined vibration pattern recorded in the memory 16 is, for example, a vibration cycle. This can be registered in the memory 16 by the user.
[0019]
In this case, the control unit 15 cancels the power saving mode when the period of vibration detected by the vibration sensor 14 is equal to a predetermined vibration period recorded in the memory 16.
[0020]
The timer 17 measures a predetermined time according to an instruction from the control unit 15. The power supply control unit 18 supplies power to each unit from a battery or the like (not shown) under the control of the control unit 15. The display control unit 19 performs display control for causing the display unit 20 to display out-of-service display, a dial number for transmission / reception, and the like. The display unit 20 is an LCD (Liquid Crystal Display) or the like.
[0021]
The transmitter 21 converts the user's voice signal into a transmission signal and sends it to the transmitter 11. The receiver 22 converts the received signal received by the receiving unit 12 into an audio signal and sends it out.
[0022]
FIG. 2 is a flowchart showing the operation of the mobile phone shown in FIG. FIG. 2 shows a transition method between the normal mode and the power saving mode of the mobile phone 1.
[0023]
1 and 2, first, when a power-on signal is input from the operation key unit 13, the control unit 15 controls the power control unit 18 to turn on the power of the main body of the mobile phone 1 and set the operation mode to the normal mode. And control of each part is started in the normal mode (step S1).
[0024]
Thereafter, the control unit 15 instructs the timer 17 for shifting the operation mode from the normal mode to the power saving mode to measure a predetermined time. Thereby, the timer 17 starts measuring time (step S2). Next, it is determined whether the timer 17 has expired by counting the predetermined time (step S3).
[0025]
When the control unit 15 determines that the timer 17 has expired, that is, when a notification (time-saving mode shift instruction) indicating that the timer has expired is input from the timer 17 to the control unit 15 (Yes in step S3), the control unit 15 Then, the operation mode is changed from the normal mode to the power saving mode (step S4), and the power supply control unit 18 is controlled to cut off the power supply to at least an unnecessary part that is not currently used, for example, the display unit 20 or the like.
[0026]
After shifting to the power saving mode, the control unit 15 notifies the vibration sensor 14 of the start of vibration detection. When the vibration sensor 14 detects vibration applied to the mobile phone 1, the vibration sensor 14 sends an electrical signal corresponding to the vibration to the control unit 15.
[0027]
The control unit 15 determines whether or not predetermined vibration is applied to the mobile phone 1 (step S5). That is, the control unit 15 has a vibration pattern (vibration characteristics, for example, a cycle) in which the vibration applied to the mobile phone 1 is pre-registered in the memory 16 based on the electrical signal from the vibration sensor 14. Is determined (step S5).
[0028]
When it is determined that the vibration applied to the mobile phone 1 has predetermined characteristics, that is, when the user shakes the mobile phone 1 with a pre-registered rhythm (step S5, Yes), the control unit 15 The power saving mode is canceled and the operation mode is shifted to the normal mode (step S1), and the power supply control unit 18 is controlled to supply power to the portion where the power supply is cut off in step S4 (for example, the display unit 20). To do.
[0029]
As described above, in the present invention, the mobile phone 1 is provided with the vibration sensor 14, and the mode is changed from the power saving mode to the normal mode according to the vibration applied to the mobile phone 1 detected by the vibration sensor 14. Therefore, even when the user is wearing gloves or the mobile phone 1 is put in the case, the user can cancel the power saving mode only by applying a predetermined vibration to the mobile phone 1. Therefore, it is possible to promptly shift from the power saving mode to the normal mode when the user desires.
[0030]
The processing operation according to the flowchart shown in FIG. 2 can of course be realized by causing a computer, which is a CPU (control unit), to read and execute a program stored in advance in a storage medium such as a ROM. It is.
[0031]
The mobile phone 1 shown in FIG. 1 includes the vibration sensor 14. However, the present invention is not limited to this. For example, an acceleration sensor that detects the acceleration of the mobile phone 1 is provided instead of the vibration sensor 14. May be. In this case, when the operation mode is the power saving mode, the control unit 15 cancels the power saving mode according to the acceleration detected by the acceleration sensor.
[0032]
Specifically, a predetermined acceleration is stored in the memory 16 in advance, and the control unit 15 cancels the power saving mode when the acceleration detected by the acceleration sensor is equal to the acceleration stored in the memory 16. Obviously, the same effect as that of the mobile phone shown in FIG. 1 can be obtained.
[0033]
【The invention's effect】
The effect of the present invention is that the user can promptly shift from the power saving mode to the normal mode when desired. The reason is that a detecting means for detecting the movement of the mobile phone (for example, a vibration sensor for detecting vibration) is provided, and the mode shifts from the power saving mode to the normal mode according to the detected movement (vibration) of the mobile phone. As a result, even if the user is wearing gloves or the mobile phone is in the case, the user can switch from the power saving mode to the normal mode without removing the glove or taking out the mobile phone from the case. This is because the transition can be made.
