  Although an example in which the mobile phone 1 includes the LCD 15 is shown here, an organic EL (ElectroLuminescence) display may be used instead of the LCD 15.

  The operation side unit 3 and the display side unit 2 are rotatably connected by a hinge mechanism, and the operation side unit 3 and the display side unit 2 can be opened and closed.

  When the mobile phone 1 is folded and the operation side portion 3 and the display side portion 2 are in the closed state, the state of the mobile phone 1 is the closed style, the mobile phone 1 is opened, the operation side portion 3 and the display side portion The state of the mobile phone 1 when 2 is in the open state is the open style.

FIG. 2 is an exploded perspective view of the mobile phone in the present embodiment.
FIG. 3 is a perspective view of the mobile phone 1 in a closed state (closed style) when the outer side surface of the operation side portion 3 is viewed obliquely from above.

Referring to FIG. 2, mobile phone 1 includes a storage portion 3 </ b> A for storing battery 4 on the outer surface of operation side portion 3, and a slide-type security switch 7.

  The mobile phone 1 includes a buzzer generating circuit 34 (see FIG. 3). The buzzer generating circuit 34 is in a state where the security switch 7 is turned off when the security switch 7 is in the position housed in the operation side portion 3. The circuit is opened and no buzzer sound is generated from the second speaker 12.

  The buzzer generating circuit 34 is turned on when the security switch 7 slides and moves to a position where a part of the security switch 7 protrudes outside the operation side portion 3, the circuit is closed and the buzzer sound is transmitted to the second speaker 12. Generate from.

  The battery 4 is fixed by screwing with a screw 5 in a state of being stored in the storage portion 3A, and cannot be easily removed.

  This is to prevent the buzzer sound from being easily stopped by removing the battery 4 while the security switch 7 is in the ON state and the buzzer generating circuit 34 is outputting the buzzer sound from the second speaker 12.

  In a state where the battery 4 is fixed to the storage portion 3A, the storage portion 3A is covered with the lid 6.

  Referring to FIG. 3, a mobile phone 1 includes a control unit 21 for controlling the entire mobile phone 1, a radio circuit 22 connected to an antenna 22A, a codec unit 28 for processing audio data, A switching unit 29 for switching input / output of the codec unit 28, a microphone 13, a first speaker 11, a second speaker 12, a microphone terminal 16 and an earphone terminal 17 connected to the switching unit 29, a camera 24, Controls the display of the global positioning system (GPS) 23 for measuring the position of the mobile phone 1, the operation key 14 for accepting the input of the user's operation, the attitude detection switch 19, the vibration unit 26, and the LCD 16. A display control unit 30 for storing, a ROM (Read Only Memory) 31 for storing a program executed by the control unit 21, and the like. A RAM (Random Access Memory) 32 used as a work area of the control unit 21, an EEPROM (Electronically Erasable and Programmable ROM) 33 that stores address book data and the like in a nonvolatile manner, and a power supply control circuit 40 are included.

   The RAM 32 is connected to the backup power supply 32A, and even when power is not supplied from the power supply control circuit 40, the RAM 32 is supplied with power from the backup power supply 32A and retains stored data without loss.

  The RAM 32 stores emergency contact information. The emergency contact address is a telephone number selected in advance by the user of the mobile phone 1. The emergency contact information is stored in the RAM 32 by inputting the telephone number selected by the user into the mobile phone 1. The RAM 32 can store one or more emergency contacts. Here, an example in which a total of three of the first emergency contact, the second emergency contact, and the third emergency contact is stored in the RAM 32 will be described. The emergency contact address may be a phone number included in the phone book data stored in the EEPROM 33 by the mobile phone 1.

In this case, the phone book data may be marked with an emergency contact.
Further, the RAM 32 stores an emergency flag in a predetermined area.

  The emergency flag stores ON when the mobile phone is in the emergency mode, and stores OFF when the mobile phone is not in the emergency mode.

  The posture detection switch 19 detects a relative position between the operation side unit 3 and the display side unit 2 and outputs it to the control unit.

  Based on the output of the posture detection switch 19, the control unit 21 detects whether the posture of the mobile phone 1 is in the closed style or the open style.

  The radio circuit 22 receives the radio signal received by the antenna 22 </ b> A and outputs an audio signal obtained by demodulating the radio signal to the codec unit 28.

  The radio circuit 22 receives the audio signal from the codec unit 28 and outputs a radio signal obtained by modulating the audio signal to the antenna 22A.

  The codec unit 28 decodes the audio signal input from the radio circuit 22, converts the decoded digital audio signal to analog, amplifies it, and outputs it to the switching unit 29.

  The codec unit 28 receives an analog audio signal from the microphone 13 or the microphone terminal 16 via the switching unit 29, converts the audio signal to digital, encodes it, and sends the encoded audio signal to the radio circuit 22. Output.

  The switching unit 29 is controlled by the control unit 21 and switches input / output of audio signals to the codec unit 28.

  The switching unit 29 outputs the audio signal received from the codec unit 28 to any one of the earphone terminal 17, the first speaker 11, and the second speaker 12.

  When the earphone is connected to the earphone terminal 17, the audio signal received from the codec unit 28 is output to the earphone terminal 17.

  When the earphone is not connected to the earphone terminal 17, if the mobile phone 1 is in the hands-free mode, the audio signal received from the codec unit 28 is output to the second speaker 12, and the mobile phone 1 is not in the hands-free mode. The audio signal received from the codec unit 28 is output to the first speaker 11.

  When the user operates the operation key 14, the mobile phone 1 is set to the hands-free mode.

  Further, even if the mobile phone 1 is in the open style and is not in the hands-free mode, the control unit 21 sets the hands-free mode when the state of the mobile phone 1 changes to the closed style.

  Therefore, the switching unit 29 outputs the audio signal received from the codec unit 28 to the first speaker 11 if the mobile phone 1 is not set to the hands-free mode when the mobile phone 1 is in an open style and is in a talking state. When the state changes to the closed style, the audio signal received from the codec unit 28 is output to the second speaker 12.

  The switching unit 29 outputs an audio signal output from either the microphone 13 or the microphone terminal 16 to the codec unit 28. The switching unit 29 outputs the audio signal received from the microphone terminal 16 to the codec unit 28 when the microphone is connected to the microphone terminal 16, and from the microphone 13 when the microphone is not connected to the microphone terminal 16. The received audio signal is output to the codec unit 28.

  The buzzer generation circuit 34 includes a security switch 7. The buzzer generating circuit 34 is connected to the second speaker 12 and outputs a buzzer sound to the second speaker 12 when the security switch 7 is in an ON state. As a result, a buzzer sound is generated from the second speaker 12. The buzzer generating circuit 34 outputs a buzzer sound only to the second speaker 12 and does not output a buzzer sound to either the first speaker 11 or the earphone terminal 17. Further, the buzzer generation circuit 34 outputs the state (closed state or open state) of the buzzer generation circuit 34 to the control unit 21.

The display control unit 30 is controlled by the control unit 21 and controls the LCD 16 according to an instruction input from the control unit 21 to display an image on the LCD 16.
The image displayed on the LCD 16 includes a moving image and a still image.

A removable flash memory 27A is attached to the card I / F 27.
The control unit 21 can access the flash memory 27A via the card I / F 27.

Although an example in which a program to be executed by the control unit 21 is stored in the ROM 31 will be described here, the program is stored in the flash memory 27A, the program is read from the flash memory 27A, and the control unit 21 You may make it perform.
The recording medium for storing the program is not limited to the flash memory 27A, but is a flexible disk, cassette tape, optical disk (CD-ROM (Compact Disc-ROM) / MO (Magnetic Optical Disc) / MD (Mini Disc) / DVD (Digital). Versatile Disc)), an IC card (including a memory card), an optical card, a semiconductor memory such as a mask ROM, EPROM, or EEPROM.

  Alternatively, the mobile phone 1 may be connected to the Internet via the wireless circuit 22, and a program may be downloaded from a computer connected to the Internet and executed by the control unit 21.

  The program here includes not only a program directly executable by the control unit 21 but also a program in a source program format, a compressed program, an encrypted program, and the like.

The camera 24 includes a lens and a CMOS (Complementary Metal O
A photoelectric conversion element such as a xide semiconductor sensor is provided, and the light condensed by the lens is imaged on the CMOS sensor. The CMOS sensor photoelectrically converts the received light and outputs image data to the control unit 21.

  The camera 24 is controlled by the control unit 21, starts imaging in response to an instruction from the control unit 21, and outputs the obtained still image data or moving image data to the control unit 21.

  The camera 24 includes an image processing circuit that executes image processing for improving the image quality of image data, and an A / D conversion circuit that converts image data from analog to digital.

  The control unit 21 outputs still image data or moving image data output from the camera 24 to the display control unit 30 and displays it on the LCD 16 or encodes the still image data or moving image data using a compression encoding method, The data is stored in the flash memory 27A attached to the card I / F 27.

  The camera 24 images the user of the mobile phone 1 when the mobile phone 1 functions as a video phone.

  The power supply control circuit 40 includes a power supply control unit 41, a battery 4, and an external power supply terminal 43 to which an external power supply 44 is connected, and supplies power to each load of the mobile phone 1.

  The battery 4 is a secondary battery such as a nickel cadmium battery, a nickel hydrogen battery, or a lithium polymer battery. An external power supply 44 is connected to the external power supply terminal 43. The external power supply 44 is an A / C adapter connected to a commercial power supply. The external power supply terminal 43 includes a USB cable connection terminal. In this case, the external power supply 44 is an electronic device connected to a USB cable.

  The power supply control circuit 40 outputs power supplied from the external power supply 44 when the external power supply 44 is connected to the external power supply terminal 43, and if the external power supply 44 is not connected to the external power supply terminal 43, The electric power supplied from the battery 4 is output.

  The power supply control unit 41 detects the voltage applied to each load including the control unit 21 of the mobile phone 1 and controls the power applied to each load.

  When the power supply control unit 41 detects the voltage of the battery 4 and the voltage of the battery 4 is lower than the voltage necessary to drive each load of the mobile phone 1 or when the battery 4 is removed, The power supply to each load of the mobile phone 1 is cut off.

  The power control circuit 40 is connected to the power key 14A of the operation key 14, and supplies power to the power key 14A in order to detect that the power key 14A is pressed when the power is connected. .

  When the power supply control unit 41 detects an operation of pressing the power key 14A by the user in a state where power supply to each load including the control unit 21 of the mobile phone 1 is cut off, the control unit 21 of the mobile phone 1 Power is supplied to each load including

  In addition, when the external power supply 44 is connected to the external power supply terminal 43 or when another battery 4 that has accumulated sufficient power is attached, the power supply control unit 41 executes a power supply process described later, Electric power is supplied to each load including the control unit 21 of the mobile phone 1 without detecting pressing of the power key 14A.

  Control unit 21 includes a mode switching unit 51.

  When the mode switching unit 51 detects that the buzzer generation circuit 34 is closed, the mode switching unit 51 switches from the normal mode to the emergency mode.

  The controller 21 executes emergency processing in the emergency mode. Although the emergency process will be described later, it is a process that is not executed in the normal mode. The mode switching unit 51 switches the emergency mode to the normal mode on condition that the emergency process is completed after switching to the emergency mode. For this reason, even if the buzzer generation circuit 34 is opened after the switching to the emergency mode and the buzzer sound is generated, if the emergency process is not completed, the emergency mode is maintained without switching to the normal mode.

  The mode switching unit 51 switches from the emergency mode to the normal mode when the emergency process is completed or when a release process described later is executed by the control unit 21.

  When power is supplied to the mobile phone 1, the mobile phone 1 starts in the normal mode, but the mode switching unit 51 switches to the emergency mode when the emergency flag stored in the RAM 32 is ON.

  FIG. 4 is a flowchart illustrating an example of the flow of power supply processing.

  The power supply process is a process executed by the power supply control unit 41. The power supply control unit 41 detects whether or not a power supply is connected (step S01). The power source includes a battery 4 and an external power source 44. When the external power supply 44 is connected to the external power supply terminal 43 or when the battery 4 is attached, it is determined that the power supply is connected.

  Then, it is determined whether or not the power supply voltage exceeds a predetermined threshold value (step S02). If the power supply voltage exceeds the threshold value, the process proceeds to step S03. Return to S01.

  The process returns to step S01 when the battery 4 that is not sufficiently charged is attached.

In step S03, it is determined whether or not the emergency flag is set to ON.
The power supply control unit 41 reads out the emergency flag stored in the area assigned in advance in the RAM 32 for the emergency flag, and determines whether or not the emergency flag is set to ON.

  The emergency flag is a flag indicating whether the mobile phone 1 is in the normal mode or the emergency mode. The urgent flag is written in a pre-allocated area of the RAM 32 by the control unit 21. If the emergency flag is set to ON, the process proceeds to step S05; otherwise, the process proceeds to step S04.

  In step S04, it is determined whether or not the power key 14A is turned on. If it is detected that power key 14A is pressed, the process proceeds to step S05. If it is not detected that power key 14A is pressed, the process returns to step S01.

  In step S05, power is supplied to each load of the mobile phone 1 including the control unit 21.

Then, it is determined whether or not the voltage of the power source exceeds a predetermined threshold value (step S0).
6) If the power supply voltage exceeds the threshold value, the process returns to step S05. If the power supply voltage does not exceed the threshold value, the process proceeds to step S07.

The process proceeds to step S07 when the battery 4 stores less power or when the external power supply 44 is removed and the connection with the external power supply terminal 43 is released.
In step S07, power supply to each load of the mobile phone 1 including the control unit 21 is stopped.
Thereby, the control unit 21 is not driven.

  As described above, when the power is connected, the power control unit 41 supplies power to the control unit 21 on the condition that the power key 14A is pressed if the emergency flag is not set to ON. If the flag is set to ON, power is supplied to the control unit 21 without detecting pressing of the power key 14A.

  Therefore, when the mobile phone 1 is in the emergency mode and the power is supplied again after the power is not supplied, the power is supplied to the control unit 21 even if the user does not input any operation to the mobile phone 1. Therefore, the control unit 21 can execute an emergency process to be described later.

  FIG. 5 is a flowchart showing an example of the flow of main processing executed by the control unit of the mobile phone.

  The main process is a process executed by the control unit 21 after the power is supplied to the control unit 21 and driven.

The control unit 21 determines whether or not the emergency flag is set to ON (step S11).
The control unit 21 reads data in an area previously assigned to the RAM 32 for the emergency flag, and determines whether or not the emergency flag is set to ON.
If the emergency flag is set to ON, the process proceeds to step S12; otherwise, the process proceeds to step S16.

  When the process proceeds to step S12, the mode switching unit 51 switches the mobile phone 1 to the emergency mode.

In step S12, an emergency process is executed. Details of the emergency processing will be described later.
Then, the emergency flag is set to OFF (step S13).
The data in the area allocated in advance for the emergency flag in the RAM 32 is rewritten to OFF.
Thereby, the mobile phone is switched from the emergency mode to the normal mode.

  When the process proceeds to step S13, the mode switching unit 51 switches the mobile phone 1 to the normal mode.

  In the next step S14, normal processing executed in the normal mode is executed.

  Then, it is determined whether or not an instruction to turn off the power is accepted (step S15). If the instruction to turn off the power is accepted, the process is terminated. Otherwise, the process proceeds to step S16.

  The instruction to turn off the power is, for example, an operation of pressing the power key 14A for a predetermined time or more.

  In step S16, it is determined whether or not the security switch 7 has been turned ON. If security switch 7 is switched ON, the process proceeds to step S17. If not, the process proceeds to step S14.

  When detecting that the state of the buzzer generating circuit 34 has changed to the closed state, the control unit 21 determines that the crime prevention switch 7 has been switched ON. When the process proceeds to step S <b> 17, the mobile phone 1 is switched to the emergency mode by the mode switching unit 51.

  In step S17, the emergency flag is set to ON. The data in the area allocated in advance for the emergency flag in the RAM 32 is rewritten to ON.

In step S18, it is determined whether a call is in progress.
If a call is in progress, the process proceeds to step S19; otherwise, the process proceeds to step S12. In step S19, it is determined whether or not the telephone number assigned to the other party's telephone during a call matches the emergency contact.

  If there are a plurality of emergency contact addresses, if they do not match any of them, the process proceeds to step S20, and if they match any one, the process proceeds to step S12.

  In step S20, the call is disconnected. This is because the emergency process described below is executed at an early stage.

  In this way, the control unit 21 executes the main process when power is supplied. When the main process is executed, the emergency flag is first read. If the emergency flag is set to ON, the emergency process is executed.

  The controller 21 sets the emergency flag to ON in the emergency mode.

  For this reason, even if the power is cut off when the mobile phone 1 is in the emergency mode and the emergency process is interrupted in the middle, the emergency flag is set to ON when the power is next supplied, The unit 21 can execute emergency processing.

  Further, when the mobile phone 1 is in the normal mode, the power is cut off, and the next time power is supplied, the emergency flag is not set to ON, so that the control unit 21 does not execute the emergency process. Can be.

  FIG. 6 is a flowchart illustrating an example of the flow of emergency processing. The emergency process is a process executed in step S12 of FIG. That is, the emergency process is a process executed when the emergency flag is set to ON and the mobile phone 1 is in the emergency mode.

Referring to FIG. 6, control unit 21 acquires position information (step S21). The GPS 23 is made to acquire the position of the mobile phone 1. And the positional information which GPS23 outputs is received.
The control unit 21 transmits the acquired position information to a predetermined transmission destination (step S22).
And it will be in a standby state until transmission of positional information is completed (it is NO at step S23), and if transmission of positional information is completed, a process will be advanced to step S24.

  Note that the processing after step S24 may be executed instead of waiting for the transmission of the position information to be completed.

  However, in order to end the emergency process, one condition is to complete the transmission of the position information.

  In step S24, the emergency contact address is read from the RAM 32. Here, the three telephone numbers of the first to third emergency contacts are read out. And the transmission process of the 1st emergency contact transmitted to a 1st emergency contact is performed (step S25). The first emergency contact transmission process will be described later, but is a process that enables a call with the first contact telephone.

  When the transmission process of the first emergency contact is completed, it is determined whether an incoming call is detected (step S26).

  If an incoming call is detected, the process proceeds to step S27. If not detected, step S27 is skipped and the process proceeds to step S28.

  Next, a transmission process of the second emergency contact to be transmitted to the second emergency contact is executed (step S28). The outgoing call process of the second emergency contact will be described later, but is a process that enables a call with the telephone of the second contact. When the outgoing call processing of the second emergency contact is completed, it is determined whether or not an incoming call is detected (step S29). If an incoming call is detected, the process proceeds to step S30. If not detected, step S30 is skipped and the process proceeds to step S31.

  Next, the third emergency contact sending process for sending to the third emergency contact is executed (step S31). The third emergency contact address transmission process will be described later, but is a process that enables a call with the third contact telephone. When the transmission process of the third emergency contact is completed, it is determined whether an incoming call is detected (step S32).

  If an incoming call is detected, the process proceeds to step S33. If not detected, step S33 is skipped and the process proceeds to step S34.

  Since the first emergency contact sending process, the second emergency contact sending process, and the third emergency contact sending process are different only in the handling of the emergency contact, they are hereinafter collectively referred to as a sending process.

  In step S34, it is determined whether or not a call is possible with all the first to third emergency contacts and the call is completed.

  For example, a completion flag may be assigned to an emergency contact that has made a call and the call has been completed, and it may be determined that the completion flag has been assigned to all emergency contacts.

  If a call can be made between all the first to third emergency contact telephones, the process is terminated. However, any one of the first to third emergency contact telephones can be called. If there is an emergency contact that has not been made, the process proceeds to step S35.

In step S35, it is determined whether or not an incoming call is detected. If an incoming call is detected, the process proceeds to step S36. If not detected, step S36 is skipped and the process proceeds to step S37. In step S36, incoming call processing is executed. In step S37, it is determined whether or not 60 seconds have elapsed. If 60 seconds have elapsed, the process returns to step S25, and if not, the process returns to step S35. The starting point for 60 seconds is step S2.
5. When the outgoing call process executed last in step S28 or step S31 is completed, or when the incoming call process is executed in step S27, step S30 or step S33, the incoming call process executed last is When it is finished.

  In other words, if there is an incoming call for 60 seconds from the end of the outgoing call process, or 60 seconds after the incoming call process is completed when the incoming call process is executed, the incoming call process is executed (step S36). If there is no incoming call, the processing after step S25 is executed again.

  If the number of times the process after step S25 is executed is the second time or later, if step S25 is executed and a call can be made with the first emergency contact telephone once, step S25 is skipped thereafter. .

  Similarly, if step S28 is executed and a call can be made with the second emergency contact telephone once, step S28 is skipped thereafter, and step S31 is executed to execute the third emergency contact. If a telephone call can be made even once, step S31 is skipped thereafter.

  It should be noted that even if a telephone number as an emergency contact is registered by the user's setting, the mode setting may be made so as to invalidate this outgoing call processing.

FIG. 7 is a flowchart illustrating an example of a flow of outgoing call processing.
The transmission process is a process executed in step S25, step S28, and step S31 in FIG. With reference to FIG. 7, an emergency contact is called (step S41). Then, it is determined whether or not the emergency contact telephone has responded (step S42). If the emergency contact telephone answers, the call can be made. If the emergency contact telephone answers, the process proceeds to step S46, and if not, the process proceeds to step S43.

In step S43, it is determined whether or not the answering machine is set. If the answering machine is set, the process ends. If not, the process proceeds to step S44.
If a signal indicating that the answering machine is set is received from the communication network, it is determined that the answering machine is set.

  In step S44, it is determined whether or not 30 seconds have elapsed since the call was made. If 30 seconds have elapsed, the process proceeds to step S45. If 30 seconds have not elapsed, the process returns to step S42.

  In step S41, the emergency contact is called, and if the emergency contact is set to the answering machine, the process is immediately terminated, otherwise the call is continued for 30 seconds.

  If no response is received after 30 seconds, the process is terminated.

  This is because the call time to one emergency contact is limited so that a call to the telephone of the next emergency contact can be made at an early stage without continuing the call to the emergency contact that never responds.

  In step S46, the vibration unit 26 is vibrated for a predetermined time.

  This vibration operation can be set by the user so as to operate even during normal transmission, but the processing in step S46 may be performed regardless of the user's setting (regardless of the vibration mode).

  In step S41, a call is made to the emergency contact. This call is not based on a call operation by the user of the mobile phone 1, but the mobile phone 1 automatically makes a call in the emergency mode.

  Since a call is made without the user's knowledge and a response is made without the user's knowledge, the vibration unit 26 is vibrated when a response is made, thereby enabling a call to be made with the emergency contact telephone. The user can be notified that it has become.

  In addition, the calling process may be executed when the crime prevention switch 7 is turned on, so that a call is made with the emergency contact telephone by using vibration instead of sound. It is possible to make it easier for the user to notice that this is possible.

  In step S47, the output of the microphone 13 is muted. Then, reproduction of a predetermined message is started (step S48). The reproduced message is transmitted to the emergency contact telephone where the telephone call can be made. The message is a message that can inform the user of the emergency contact telephone that an emergency has occurred, for example, “An emergency has occurred. Please help.”

  Then, it is determined whether or not the message reproduction has ended (step S49). If the message reproduction has ended, the process proceeds to step S50, and if not, the process returns to step S48.

  While the message is being played and sent to the emergency contact, the output of the microphone 13 is muted.

  As a result, it is possible to prevent the message from being erased by the buzzer sound fetched from the microphone 13 and not being able to notify the user of the emergency contact telephone.

  In step S46, the vibration unit 26 is vibrated to notify the response. However, the vibration unit 26 may be vibrated until the message reproduction ends in step S49.

  Thereby, when the vibration of the vibration unit 26 is finished, it is possible to notify the user that the reproduction of the message is finished and the telephone can be talked.

  In step S50, it is determined whether or not the crime prevention switch 7 is in an ON state. If the security switch 7 is ON, the process proceeds to step S51. If not, the process proceeds to step S52.

  While detecting that the buzzer generation circuit 34 is in the closed state, the control unit 21 determines that the security switch 7 is in the ON state and detects that the buzzer generation circuit 34 is in the open state. Meanwhile, it is determined that the crime prevention switch 7 is in an OFF state.

  In step S51, the microphone 13 is turned on with low sensitivity. Since the buzzer generating circuit 34 outputs the buzzer sound from the second speaker 12, the microphone 13 prevents the buzzer sound from being collected as much as possible, and a loud buzzer sound is output from the speaker of the emergency contact telephone. This is to prevent this.

  On the other hand, in step S52, the microphone 13 is turned on with high sensitivity.

  This is because the buzzer generation circuit 34 does not output the buzzer sound from the second speaker 12, so that it is not necessary to lower the sensitivity of the microphone 13.

  In step S53, it is determined whether or not the crime prevention switch 7 has been switched from ON to OFF. If the crime prevention switch 7 has been switched to OFF, the process proceeds to step S54. If the crime prevention switch 7 has not been switched, the process skips step S54. Advances to step S55.

  When the security switch 7 is turned off, the buzzer generation circuit 34 does not output a buzzer sound to the second speaker 12. For this reason, in step S54, the sensitivity of the microphone 13 is increased.

  In step S55, it is determined whether or not the security switch 7 has been switched from OFF to ON. If the security switch 7 has been switched to ON, the process proceeds to step S56, and if not switched, the process proceeds to step S57.

  When the crime prevention switch 7 is turned ON, the buzzer generating circuit 34 is closed, so that the buzzer generating circuit 34 outputs a buzzer sound to the second speaker 12. In step S56, the buzzer generating circuit 34 is controlled to Control the volume.

  Specifically, the buzzer sounding circuit 34 is caused to output a buzzer sound whose volume is gradually increased as time elapses to the second speaker 12.

  For example, the buzzer generation circuit 34 outputs a buzzer sound with a low volume for the first 5 seconds, outputs a buzzer sound with a medium volume for the next 5 seconds, and then outputs a buzzer sound with a high volume after that. The second speaker 12 outputs a buzzer sound whose sound increases in steps as time passes.

  This buzzer sound output method is called step-up output. Rather than suddenly outputting a loud buzzer sound, the buzzer sound was suddenly output from the speaker of the emergency contact phone because the buzzer sound was output by gradually increasing the volume. Can be prevented. In step S57, the sensitivity of the microphone 13 is lowered as in step S51.

  Instead of increasing the buzzer sound step by step, the buzzer sound may be increased in proportion to the passage of time. Further, step S56 and step S57 may be reversed, and in this case, the influence due to the notification of the re-buzzer sound can be suppressed.

  In step S58, it is determined whether or not the call is disconnected. If the call is disconnected, the process ends. If the call is not disconnected, the process returns to step S53.

  FIG. 8 is a flowchart illustrating an example of the flow of incoming call processing. The incoming call process is a process executed when an incoming call is detected in each of steps S27, S30, S33, and S36 in FIG. Referring to FIG. 8, control unit 21 determines whether or not the call is from an emergency contact telephone (step S61).

  Specifically, it is determined whether or not the telephone number received together with the detected incoming call is stored in the RAM 32 as an emergency contact address. If it is an incoming call from the emergency contact telephone, the process proceeds to step S62; otherwise, the process proceeds to step S79. In step S79, the incoming call is rejected and the process is terminated. This is to make it possible to make only a call with a telephone necessary for an emergency situation by not making a call with a telephone having a telephone number other than the emergency contact possible.

In step S62, an incoming call notification is made to notify the user that an incoming call has been received.
The incoming call notification causes the vibration unit 26 to vibrate. Even if the notification by the vibration of the vibration unit 26 is not set in the incoming call notification setting, the vibration unit 26 is vibrated in step S62. The incoming call notification is executed when the security switch 7 may be turned on, and the notification is made by vibration rather than by sound, so that the user can easily recognize that there is an incoming call. In the emergency mode, regardless of whether the buzzer is sounding or not, the incoming call is notified by vibrating the vibration unit 26.

  For this reason, even if the crime prevention switch 7 is switched to OFF while the vibration part 26 is vibrating, it continues to vibrate until the incoming notification is stopped in step S66 described later.

  In the normal mode, it is possible to notify the incoming call by the ring tone. However, in the emergency mode, the buzzer may sound. The incoming call is notified.

  Then, it is determined whether the incoming call from the emergency contact is a request for a videophone call (step S63). If it is an incoming call requesting a videophone call, the process proceeds to step S80; otherwise, the process proceeds to step S64. In step S64, it is in a standby state for 5 seconds (NO in step S64), and if 5 seconds have elapsed, the process proceeds to step S65. For this reason, the incoming call notification started in step S62 is performed for 5 seconds.

  Note that the standby time is not limited to 5 seconds, and may be a predetermined time. In step S65, the incoming call is automatically answered.

As a result, a call can be made to the emergency contact telephone. If the user of the mobile phone 1 switches the crime prevention switch 7 to ON and a call is received from the emergency contact telephone, the user can make a call with the telephone. It is possible to deal with an emergency without being confused.
In step S66, the incoming call notification started in step S62 is stopped. Specifically, the vibration by the vibration unit 26 is stopped.

  Since the processing from step S67 to step S78 is the same as the processing from step S47 to step S58 shown in FIG. 7, description thereof will not be repeated here.

The process proceeds to step S80 when an incoming call requesting a videophone call is detected. In step S80, it is determined whether a response instruction has been accepted.
If it is detected that the user depresses the call button of the operation key, the process proceeds to step S81. If not detected, the process proceeds to step S82. This is to allow the user to select whether or not to respond to an incoming call requesting a videophone call.

  It should be noted that the reason for not automatically responding to an incoming call requesting a videophone call in steps S63 to S65 is that if an automatic response is received to an incoming call requesting a videophone call, An image that is not desired to be transmitted may be transmitted, and the intention of the user is confirmed. Another purpose is to prevent invasion of personal privacy by using a videophone for the purpose of mischief.

In step S81, the incoming call is answered. As a result, a videophone call can be made with the emergency contact telephone. If the user of the mobile phone 1 switches the crime prevention switch 7 to ON and a call is received from the emergency contact telephone, the user can make a call with the telephone. It is possible to deal with an emergency without being confused. In step S66, the incoming call notification started in step S62 is stopped. Specifically, the vibration by the vibration unit 26 is stopped.

  On the other hand, in step S82, it is determined whether or not the incoming call is finished. If the incoming call is finished, the process proceeds to step S83. If the incoming call is not finished, the process returns to step S80.

  In step S83, the incoming call notification started in step S62 is terminated, and the process is terminated.

  FIG. 9 is a flowchart illustrating an example of the flow of release processing.

  The canceling process is a process executed by the control unit 21 to cancel the emergency mode. When the control unit 21 detects pressing of a predetermined operation button when the mobile phone 1 is in the emergency mode, the control unit 21 generates an interrupt and executes a canceling process. The predetermined operation button is a button predetermined for the operation key 14.

  Referring to FIG. 9, control unit 21 causes LCD 15 to display a password input screen (step S91). If the password is received (YES in step S92), the received password is authenticated (step S93). The received personal identification number is compared with the personal identification number previously stored in the RAM 32 or the like, and if the two coincide, the accepted personal identification number is authenticated, and if the two coincide, the received personal identification number is not authenticated. If the authentication is successful, the process proceeds to step S94. If the authentication fails, the process ends.

  Here, the password is used for authentication, but biometric information such as a fingerprint, an iris, and a vein pattern may be used for authentication.

  In step S94, the emergency flag is set to OFF. The data in the area allocated in advance for the emergency flag in the RAM 32 is rewritten to OFF. Thereby, the mobile phone is switched from the emergency mode to the normal mode. Then, the emergency process is terminated (step S95), and the process is terminated. The end of the emergency process ends the process at that stage even if the emergency process shown in FIG. 6 is being executed.

  For example, when the first emergency contact is called out and the call is in a call waiting state, the call is stopped and the process ends. For this reason, even if the user accidentally switches the crime prevention switch 7 to ON, the above-described emergency processing can be stopped halfway.

  In some cases, the crime prevention switch 7 may be turned on in a state in which a call can be made with the emergency contact, for example, the telephone of the first emergency contact (step S16 in FIG. 5). In this case, as shown in FIG. The emergency process is executed (step S12), but the emergency process is executed after executing the process of steps S67 to S78 of the incoming call process shown in FIG. For this reason, a message to the effect that the call is urgent is transmitted to the other party. For this reason, it is possible to automatically notify the other party of the call that an emergency has occurred.

  Furthermore, the first emergency contact is completed when the state in which a call can be made with the telephone of the first emergency contact is completed, in other words, when the processing of steps S67 to S78 of the incoming call processing is completed. It is preferable not to execute the first emergency contact calling process (step S25 in FIG. 6) by adding a flag.

  As a result, it is possible to prevent a call with the same telephone from being made possible again.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
