As shown in FIG. 3, the mobile phone device 1 includes an operation unit 11 (key operation unit), a microphone 12, a main antenna 40, an RF circuit unit 41, an LCD control unit 42, an audio processing unit 43, A memory 44 and a control unit 45 are provided in the operation unit side body 2, and an LCD display unit 21 (display unit), a speaker 22, a driver IC 23, and a sub LCD display unit 30 are included in the display unit side case. The body part 3 is provided.

  The main antenna 40 communicates with a base station or the like in a first use frequency band (for example, 800 MHz), and can support a second use frequency band (for example, 1.5 GHz) for GPS communication. It is. In the present embodiment, the first frequency band used is 800 MHz, but other frequency bands may be used. Further, the main antenna 40 may be separately provided with an antenna that communicates with an external device in the first use frequency band and can correspond to the second use frequency band for GPS communication.

  The RF circuit unit 41 demodulates the signal received by the main antenna 40 and supplies the processed signal to the control unit 45. Then, the signal supplied from the control unit 45 is modulated and transmitted to an external device (base station) via the main antenna 40. On the other hand, the control unit 45 is notified of the strength of the signal received by the main antenna 40.

  The LCD control unit 42 performs predetermined image processing according to the control of the control unit 45, and outputs the processed image data to the driver IC 23. The driver IC 23 stores the image data supplied from the LCD control unit 42 in the frame memory and outputs it to the LCD display unit 21 or the sub LCD display unit 30 at a predetermined timing.

  In addition, the audio processing unit 43 processes the signal input from the microphone 12 according to the control of the control unit 45 and outputs the processed signal to the RF circuit unit 41. The RF circuit unit 41 performs a predetermined process on the signal supplied from the sound processing unit 43 and outputs the processed signal to the main antenna 40.

  The memory 44 includes, for example, a working memory and is used for arithmetic processing by the control unit 45. The memory 44 stores a plurality of applications and various tables necessary for the applications. The memory 44 may also serve as a removable external memory.

  The control unit 45 controls the entire mobile phone device 1 and is configured using a central processing unit (CPU) or the like. Here, the control operation of the control unit 45 according to the key operation by the operation unit 11 will be described. In principle, the control unit 45 assigns symbols and functions to each key (the function setting operation key 13, the input operation key 14, and the determination operation key 15) constituting the operation unit 11 in accordance with an application that is currently actively activated. To change.

  Specifically, when any key is pressed, the operation unit 11 displays the position information of the key (for example, as shown in FIG. 4A, the left column of the second row of the input operation key 14). When the key (the key with “1” and “a” printed on the front surface) is pressed, the position information (X2, Y1) is transmitted to the control unit 45. The control unit 45 accesses the memory 44, refers to the key assignment table corresponding to the currently active application, and processes the symbols and functions assigned from the position information transmitted from the operation unit 11. Run. For example, as shown in FIGS. 4B to 4D, the memory 44 stores a plurality of key assignment tables. 4B is a table used when making a call, FIG. 4C is a table used in a notepad application or a mail application, and FIG. It is a table used when changing a channel in a television application.

  The execution of the symbol processing means, for example, that “1” or “A” is displayed on the LCD display unit 21 when the currently active application is Notepad. The execution of the function processing means, for example, that the display channel is set to 1ch when the currently active application is a television.

  In this way, the memory 44 stores a plurality of key assignment tables, and the control unit 45 switches the key assignment table to be referenced according to the application, and positions of keys transmitted from the operation unit 11. A predetermined process is executed by referring to a predetermined key assignment table based on the information.

  In the mobile phone device 1 configured as described above, when a key operation is performed in a communication standby state, each of a plurality of symbols (for example, numbers and characters) assigned to the key is separately set, for example. The screen area is displayed in parallel, and when a predetermined key operation is performed, the screen on which one symbol is displayed is enabled. In addition, the mobile phone device 1 has a function of determining whether to give priority to call processing or to reduce reduction of false calls when making a call.

Here, operation | movement of the control part 45 for exhibiting the function mentioned above is demonstrated. The operation unit 11 includes a first key (for example, a key located in the second to fifth lines of the input operation key 14 shown in FIG. 1C) and a second key (for example, a determination operation key). 15), and third key (e.g., off-hook key located in the left column top row of the input operation keys 14 (in FIG. 1 B) is configured to include a).

  The first key is a first type symbol (for example, hiragana such as “A”, “I”, “U”) and a second type symbol (for example, numbers such as “1”, “2”, “3”). And is composed of a plurality of assigned keys. The second key is a key to which a single type or a plurality of functions (for example, a function for converting kana to kanji) is assigned, without assigning the first type symbol and the second type symbol. The third key is a key to which a function different from the second key (for example, a function for making a call) is assigned, without assigning the first kind symbol and the second kind symbol.

  When the initial screen 100 waiting for an incoming call is displayed on the LCD display unit 21 (FIGS. 5A and 6A), the control unit 45 presses any one of the first keys. Control is performed so that the first type symbol assigned to the pressed key and the second type symbol assigned to the pressed key are displayed on the LCD display unit 21 (FIG. 5B). (C), FIG. 6 (b), (c)). Specifically, the control unit 45 controls to display the first type symbol in the first type symbol display area 101 and display the second type symbol in the second type symbol display area 102. The first type symbol is a symbol corresponding to hiragana such as “A”, “I”, “U”. The second type symbol is, for example, a symbol corresponding to a number such as “1”, “2”, “3”, and the like.

  When the second key is pressed while the control unit 45 is controlling to display the first type symbol and the second type symbol on the LCD display unit 21, the (first type symbol display) is performed. A first process (for example, a process of converting kana into kanji) for the first type symbol (input to the area 101) is executed (FIG. 5 (d)).

  When the third key is pressed while the control unit 45 is controlling the LCD display unit 21 to display the first type symbol and the second type symbol, the control unit 45 displays (second type symbol display). A second process (for example, a process related to a telephone call) for the second type symbol (input to the area 102) is executed.

  In addition, in the second process, the control unit 45 determines that the symbol string (telephone number) related to the second type symbol (input to the second type symbol display area 102) is a predetermined symbol string (telephone number). If the symbol string is used as a telephone number and the calling process is executed, and the symbol string is not a predetermined symbol string, after confirming whether or not the calling process is executed using the symbol string as a telephone number (for example, The confirmation display screen 104 as shown in FIG. 6D is displayed for confirmation), and the outgoing call processing is executed. When “Yes” is selected on the confirmation display screen 104 shown in FIG. 6D, a telephone call is executed based on the displayed “045943XXX”, and “NO” is selected. In this case, the screen may return to the initial screen 100 or may be returned to the previous screen (the screen in which the second type symbol display area 102 is displayed in an enlarged manner).

  Further, the predetermined symbol string is preferably a symbol string (telephone number) registered in advance or a symbol string (telephone number) for emergency call (emergency call). In addition, any contact partner registered in the address book stored in the memory 44 may be registered as a predetermined symbol string. The control unit 45 appropriately refers to the memory 44 and determines whether or not the symbol string input to the second type symbol display area 102 is a predetermined symbol string.

  By being configured in this way, the mobile phone device 1 is, for example, a phone number of a family or a close friend registered in advance with a predetermined number string (phone number), or for emergency calls (police, fire fighting, If it is a telephone number for emergency, etc., the call is made immediately without executing the confirmation process, and the confirmation process is executed for the telephone numbers other than the predetermined number string before making the call.

  Therefore, the cellular phone device 1 determines whether to give priority to the call processing or to reduce the false call based on the telephone number to be sent, and to execute the confirmation process when giving priority to the call processing. Calls can be made quickly in the event of an emergency, etc. On the other hand, if priority is given to the reduction of false calls, the call will be made after confirmation processing, reducing false calls. Can be achieved.

  Here, in the example shown in FIG. 5, when a key operation (keys on which “0” and “waon” are printed) is performed on the initial screen 100 (FIG. 5A). “Wa” is displayed in the first type symbol display area 101 where the first type symbol is displayed, and simultaneously “0” is displayed in the second type symbol display area 102 where the second type symbol is displayed ( FIG. 5B). Then, a plurality of key operations are continuously performed, “WATANABE” is displayed in the first type symbol display area 101, and “0456666 *” is displayed in the second type symbol display area 102 (FIG. 5). (C)).

When the determination operation key 15 is operated up and down while the display screen is in the state shown in FIGS. 5B and 5C, the control unit 45 executes a process of converting kana into kanji, The first type symbol display area 101 is enlarged and displayed on the display screen (FIG. 5D). The control unit 45, processing such as in the state of FIG. 5 (d), the if the left column top of the key of the input operation keys 14 (off hook key) is pressed to enlarge the character being displayed (FIG. 5E).

Further, when the display screen is in the state such as FIG. 5 (b) and FIG. 5 (c), the left column top of the key of the input operation keys 14 (off hook key) is depressed, the control unit 45, the Based on the number string displayed in the two-type symbol display area 102, the telephone call processing is performed.

In this way, the control unit 45, a key operation is performed from the communication standby state, after any symbol has been input, depending on whether the selection operation key 15 is pressed, against the off hook key, different Since the function assignment control is performed, the use efficiency of each key can be improved in the mobile phone device 1 having a small number of keys.

  Here, referring to the flowchart shown in FIG. 7, the operation of the control unit 45 when a call is made by pressing the third key based on the telephone number input in the second type symbol display area 102 is referred to. The details will be described. In the following, it is assumed that an arbitrary telephone number has already been entered in the second type symbol display area 102 and the third key has been pressed.

  In step S <b> 1, the control unit 45 determines whether the telephone number input in the second type symbol display area 102 is a predetermined telephone number (emergency call). When the telephone number input in the second type symbol display area 102 is an emergency call (Yes), the process proceeds to step S4, and the telephone number input in the second type symbol display area 102 is not an emergency call. (No), go to step S2. In this embodiment, the predetermined telephone number is an emergency call. However, the present invention is not limited to this, and a telephone number arbitrarily registered by the user may be used as the predetermined telephone number. For example, the control unit 45 refers to the address book stored in the memory 44 and determines whether or not the telephone number input in the second type symbol display area 102 is an emergency call.

  In step S <b> 2, the control unit 45 displays a confirmation screen (confirmation display screen 104) on the LCD display unit 21 as to whether or not to make a call based on the telephone number input in the second type symbol display area 102. (See FIG. 6 (d)).

  In step S <b> 3, the control unit 45 determines whether or not an outgoing operation has been performed based on the confirmation display screen 104. Specifically, when “1. Yes” is selected and operated on the confirmation display screen 104 shown in FIG. 6D, the control unit 45 determines that the outgoing operation has been performed, and “ 2. If “No” is selected, it is determined that no outgoing operation has been performed. If it is determined that a call operation has been performed (Yes), the process proceeds to step S4. If it is determined that a call operation has not been performed (No), the process proceeds to step S5.

  In step S4, the control unit 45 performs a transmission operation. By the transmission operation in this step, it is possible to make a call with another mobile phone device via the base station.

  In step S5, the control unit 45 does not perform the transmission operation, and the first state symbol display area 101 and the second kind symbol display area 102 as shown in FIG. 5C are displayed. Return to the state.

By such a configuration, the cellular telephone apparatus 1 inputs the normal telephone number, when a call, when the third key (off hook key) is depressed, as shown in FIG. 6 (d) If you select “1. Yes” or do not press “OK”, you will not be able to make a call. Can be reduced. In addition, since the mobile phone device 1 can transition to the previous screen by interposing the confirmation display screen 104 as shown in FIG. 6D, there is a possibility that data may be lost due to a transmission operation due to a malfunction. Can be reduced. Further, the cellular phone device 1 does not display the confirmation display screen 104 as shown in FIG. 6D for emergency calls (110, 119, 118, etc.) in consideration of the high level of urgency. Because it transmits, it is possible to quickly respond to emergencies.

  Note that the key assignment method shown in FIG. 4 is an example and is not limited to this method.
