Description

  The present invention relates to a communication apparatus such as a telephone apparatus or a facsimile apparatus.

  Many communication devices such as telephone devices and facsimile devices in recent years are equipped with a liquid crystal display device for displaying telephone numbers and names.

  This display device can display the telephone number entered by the user using the numeric keypad, the telephone number stored in the redial memory, etc., and the user can display the telephone number displayed on the display device before making a call. By seeing, it can be confirmed whether or not it is a desired destination.

Patent Document 1 describes a technique for displaying a telephone number stored in a redial memory so that the name corresponding to the telephone number is displayed and the destination is more easily understood. Yes.
JP-A-8-321867

  However, with the current communication device and the technology described in Patent Document 1, only the telephone number that is currently selected or entered with the numeric keypad is displayed at the time of calling, and the telephone numbers that have been called in the past are not displayed at the same time.

  For this reason, when a user inputs a wrong telephone number using the numeric keypad to make a call and then makes a call, it is not possible to check whether the previously entered telephone number is different from the currently entered telephone number. .

The present invention is for solving such a problem, and the communication device according to claim 1 includes a numeric keypad, display means for displaying a telephone number, storage means for storing the telephone number, and the numeric keypad. Calling means for making a call to the inputted telephone number, a first telephone number is inputted from the numeric keypad, and the calling means makes a call to the first telephone number, When the line connection time with the other party of the first telephone number is less than a predetermined time, the storage means stores the first telephone number, and the second telephone number by the numeric keypad after the line is disconnected. When there is an input, the display means displays the first telephone number and the second telephone number stored in the storage means .
The communication device according to claim 2 is the communication device according to claim 1, and further, does the first telephone number stored in the storage means match the second telephone number? A match determination means for determining whether or not, and a notification means, and when the display means displays the first telephone number and the second telephone number, the match determination means When it is determined that the telephone number matches the second telephone number, the notification means notifies that the telephone number matches .
Further, the communication device according to claim 3 is the communication device according to claim 2, further comprising a call instruction key, wherein the coincidence determining means includes the first telephone number and the second telephone. If it is determined that the numbers match, the calling instruction by the calling instruction key is invalidated.

  According to the present invention, since the telephone number that has been input and called in the past and the telephone number that has been input in the past can be displayed at the same time, the user is not desired (for example, an erroneous telephone number or a contact that has already been contacted in the communication network). The telephone number can be confirmed so that the user does not make a mistake again after calling the number.

  In addition, when the telephone number input in the past matches the telephone number currently input, the user does not compare the two telephone numbers displayed on the display unit one by one in order to notify the user of the matching. Both can confirm that the user has entered the wrong telephone number again.

  Further, when the telephone number input in the past matches the telephone number currently input, the user calls again to the wrong telephone number in order to prohibit calling to the telephone number currently input. This can be avoided reliably.

  In addition, since the phone number that has been called in the past and the phone number entered with the numeric keypad are displayed at the same time, the user calls the wrong phone number and then the user makes the wrong phone number again. The telephone number can be confirmed so as not to make a call first.

  Furthermore, the latest telephone number of the telephone numbers that have been called in the past is compared with the telephone number entered with the numeric keypad, and the user is displayed on the display unit in order to notify the user if they match. Without comparing the two phone numbers, it can be confirmed that the user has entered the wrong phone number again.

  In addition, the latest telephone number that has been called in the past is compared with the telephone number entered with the numeric keypad, and if they match, the call is prohibited, so the user again goes to the wrong telephone number. It is possible to reliably avoid making a call.

  Next, a mobile phone device according to an embodiment of the present invention will be described with reference to the drawings.

The communication unit 12 allows the mobile phone device 10 to communicate (call) with other communication devices (for example, a mobile phone device), to send and receive e-mails, and to connect to the Internet. Is also possible.

  The communication unit 12 is connected to the baseband unit 14. The baseband unit 14 includes a CDMA processing circuit 18 and an audio codec 20. Here, the CDMA processing circuit 18 performs code division multiple access, scrambling, error control, and timing detection. The audio codec 20 compresses (encodes) and decompresses (decodes) the audio, performs analog and digital conversion, and changes the received sound volume and microphone sensitivity by an internal amplifier circuit (not shown). .

  In addition, a switching circuit 22 is connected to the baseband unit 14. A first speaker 26 is connected to the switching circuit 22 via an amplifier circuit 24. The first speaker 26 converts the electric signal of the baseband unit 14 amplified by the amplifier circuit 24 into sound. This first speaker 26 is applied to the user's ear and used for a call.

  Further, the microphone 30 is connected to the switching circuit 22 via the amplifier circuit 28. The microphone 30 is used for a call and converts sound into an electrical signal. The electrical signal output from the microphone 30 is amplified by the amplifier circuit 28 and output to the baseband unit 14.

  Further, a second speaker 34 is connected to the switching circuit 22 via an amplifier circuit 32. The second speaker 34 converts the electric signal of the baseband unit 14 amplified by the amplifier circuit 32 into sound. The second speaker 34 is a loudspeaker for listening to the surrounding people of the received sound. The second speaker 34 also sounds an incoming call notification. Note that the gains of these three amplifier circuits 24, 28, and 32 are fixed, and the volume of the first speaker 26 and the second speaker 34 and the sensitivity of the microphone 30 cannot be changed.

  The switching circuit 22 is connected to the baseband unit 14 on the side of the amplifier circuit 24 for the first speaker 26 and the amplifier circuit 28 for the microphone 30, or the amplifier circuit 32 for the second speaker 34 for loud sound. And switching to the amplifying circuit 28 side for the microphone 30.

A control circuit (control means) 36 is connected to each of the communication unit 12, the baseband unit 14, and the switching circuit 22. Switching by the switching circuit 22 described above is performed under the control of the control circuit 36. The control circuit 36 controls the audio codec 20 of the baseband unit 14, and the audio codec 20 changes the volume of the first speaker 26 and the second speaker 34 and the sensitivity of the microphone 30.
The control circuit 36 is connected to a ROM (Read Only Memory) 38 and controls each part based on a system program stored in the ROM 38. The control circuit 36 measures a predetermined time (for example, 30 seconds).

  The control circuit 36 is connected to a RAM (Randum Access Memory) 40. The RAM 40 stores the telephone number that made the call.

  A liquid crystal display 42 is connected to the control circuit 36. The display 42 displays predetermined information such as the current time, telephone number, contents of e-mail, site image downloaded via the Internet, and display of the function name of the pressed key.

  An input unit 44 is connected to the control circuit 36. The input unit 44 includes a numeric keypad 48 for inputting a telephone number, a call key 50 for operating a call start, a cut key 52 for operating a call end, and various functions such as an electronic mail function and an Internet function. And function keys 54 for setting.

  The vibrator 56 is a vibrator for notifying an incoming call by vibration.

  The incoming call lamp 57 is lit or blinked to notify the incoming call when an incoming call is received.

  Furthermore, it has an open / close detection unit 55, and the open / close detection unit 55 detects opening / closing of the housing.

  Next, the operation of the mobile phone device 10 according to the present embodiment will be described based on the flowchart shown in FIG.

  In step S1, if the control circuit 36 determines that a telephone number has been input from the numeric keypad 48 of the input unit 44, the process proceeds to step S2.

  In step S2, the control circuit 36 performs a telephone number display process. Specifically, the process of the flowchart shown in FIG. 5 is performed.

In step S21 of FIG. 5, if the control circuit 36 determines that the data of the telephone number previously called is stored in the RAM 40, the process proceeds to step S23, and if not, the process proceeds to step S22.
In step S22, the control circuit 36 displays the telephone number input in step S1 of FIG. Specifically, for example, as shown in FIG. 6B, one telephone number (for example, 090125345678) input in step S1 is displayed. Subsequently, the control circuit 36 advances the processing to step S3 in FIG.

  In step S23, if it is determined that the telephone number input in step S1 matches the telephone number stored in RAM 40, the process proceeds to step S24, and if not, the process proceeds to step S25.

  In step S24, the control circuit 36 displays a message indicating that the same telephone number has been input on the display 42, for example, "The same telephone number has been input" and is input in step S1 of FIG. Both the telephone number and the telephone number stored in the RAM 40 are simultaneously displayed on the display 42, and the process proceeds to step S3 in FIG.

  In step S25, the control circuit 36 simultaneously displays both the telephone number input in step S1 of FIG. 4 and the telephone number stored in the RAM 40 on the display 42. Specifically, for example, as shown in FIG. 6A, two telephone numbers (for example, 09012345678 which is the telephone number input in step S1 and 09012345777 which is the telephone number stored in the RAM 40) are displayed. The Subsequently, the control circuit 36 advances the processing to step S3 in FIG.

  Returning to the flowchart of FIG. 4, in step S3, if the control circuit 36 determines that there is an operation of the call key 50, the process proceeds to step S6, and if not, the process proceeds to step S4.

  In step S4, if the control circuit 36 determines that the OFF key 52 has been operated, the display on the display 42 is cleared, and the process returns to step S1. On the other hand, if the cut key 52 is not operated, the process returns to step S2.

  In step S6, if the control circuit 36 controls the telephone communication unit 12 and the baseband unit 14 to make a call to the telephone number input in step S1 and determines that the other party has answered, the process proceeds to step S7. If not, the process proceeds to step S8.

  In step S7, the control circuit 36 stores the telephone number input in step S1 in the RAM 40. At this time, if the telephone number previously called is already stored in the RAM 40, the telephone number previously called is deleted and the telephone number newly inputted in step S1 is stored in the RAM. That is, the RAM 40 always stores the newest telephone number among telephone numbers that have been called in the past. Thereafter, the control circuit 36 advances the process to step S10.

  In this embodiment, the telephone number is stored in the RAM 40 after the other party answers at the time of calling. In the present embodiment apparatus, if the telephone number is stored in the RAM 40 before the other party answers, for example, the user is calling the desired other party's telephone number. If the destination does not respond and calls are made again to the desired destination telephone number later, not only that the same telephone number is informed but also the outgoing call to the other party is prohibited. In order to avoid such a situation, in this embodiment apparatus, the telephone number is stored in the RAM 40 after the other party answers at the time of calling.

  In step S8, if the control circuit 36 determines that there is an operation of the off key 52, the process proceeds to step S9, and if not, the process returns to step S6.

  In step S9, the control circuit 36 deletes the telephone number displayed on the display 42 and returns the process to step S1.

  In step S10, the control circuit 36 starts measuring a predetermined time (for example, 30 seconds).

In the subsequent step S11, if the control circuit 36 determines that there is an operation of the turn-off key 52, the control circuit 36 controls the telephone communication unit 12 and the baseband unit 14, thereby ending the call processing, and proceeds to step S12. On the other hand, if it is determined that no operation of the switching key 52, the process returns to S 11 step, the call is continued. In step S11, even when the other party on the call disconnects the line, the control circuit 36 proceeds to step S12.

  In step S12, the control circuit 36 proceeds to step S13 when determining that the time measurement for a predetermined time (for example, 30 seconds) started in step S10 has ended, and returns to step S1 if not.

  In step S13, the control circuit 36 deletes the telephone number stored in the RAM 40 and returns the process to step S1.

In step S12 and step S13, when the user starts a call and makes a wrong call, for example, the call time is short so as to end after speaking "I'm sorry, wrong." In this way, when the call time is short, that is, when it is a wrong call, the input telephone number is stored in the RAM 40. On the other hand, if the call time is long, that is, if the call is to a desired destination, the telephone number stored in the RAM is deleted. For this reason, only the telephone number of an undesired destination can be stored in the RAM 40. That is, after the process of step S11 is completed, in step S23 , when it is determined whether or not the same telephone number as the key input key is stored in the RAM 40, the key input telephone number is stored in the RAM 40. The telephone number of the undesired destination is compared.

  Further, not only one phone number but also a plurality of phone numbers may be stored in the RAM 40. When a plurality of phone numbers are stored, the phone number stored most recently among the phone numbers stored in the past may be used.

  In this way, in this embodiment apparatus, since the telephone number that has been called in the past at the time of the call is displayed on the display 42, both the newest telephone number and the currently entered telephone number are displayed on the display 42. It is possible to confirm whether or not the latest telephone number of the called telephone numbers is the same as the telephone number that has been called this time.

  Also, in the present embodiment device, the newest telephone number among the telephone numbers that have been called in the past is compared with the telephone number entered with the numeric keypad, and the user is notified one by one in order to notify the user if they match. Even if the two telephone numbers displayed on the screen are not compared, it can be confirmed that the user has input the wrong telephone number again.

  In addition, the latest telephone number that has been called in the past is compared with the telephone number entered with the numeric keypad, and if they match, the call is prohibited, so the user again goes to the wrong telephone number. It is possible to reliably avoid making a call.

  In the present embodiment, in step S24 in FIG. 5, a message indicating that the same telephone number has been input is displayed on the display 42. However, the incoming lamp 57 is turned on (or blinks), and the vibrator vibrates. Alternatively, it may be configured to notify the user that the same telephone number has been input by turning off (or blinking) the backlight of the display 42, or notifying the user by voice synthesis that the same telephone number has been input. May be.

  Alternatively, the telephone number stored in the RAM 40 may be deleted when a predetermined time or more elapses after the call ends. Usually, when dialing again after making a wrong call, the dialing is made again immediately after the wrong call or within several tens of seconds to several minutes at the latest. Only the telephone number of the other party can be stored in the RAM 40.

  Furthermore, in this embodiment, as shown in steps S11 to S13 of FIG. 4, when the call time has exceeded a predetermined time, it is determined that the telephone number of the other party desired by the user is entered, and a key is input. If the telephone number is not stored in the RAM 40 and the predetermined time has not elapsed, it is determined that the telephone number is not desired by the user, and the telephone number entered by key entry is stored in the RAM 40. However, the determination means for determining whether the telephone number input by the key is the telephone number of an undesired destination, for example, an erroneous call, is not limited to such a configuration. For example, if a voice recognition circuit is installed and a speech suggesting a wrong call such as "I'm sorry, I made a mistake" or "I made a mistake" The telephone number that has been called (called) may be stored in the RAM 40. Also, as described above, when a predetermined time or more has elapsed after the end of the call, it is determined that the call is made to a desired destination for the user. A configuration may be adopted in which a call to an undesired destination is determined if a predetermined time or more has not elapsed. These configurations are also considered as an example of the determination means.

  The present invention relates to a telephone function installed in an answering machine, a cordless telephone, a facsimile machine, a personal computer connected to a wired line, or a mobile phone apparatus connected to a wireless line, PHS (Personal Handyphone System). It can also be used for cordless telephone cordless handsets, PDAs (Personal Digital Assistants), and the like.
