Description of the Related Art In a normal communication device, for example, a portable telephone device, it is possible to prevent a call button or a mail send / receive button from being pressed by mistake when a user puts a portable telephone in a bag or a pocket. It has a key lock function to do so. The key lock function is, for example, a function in which a four-digit password is registered in advance, and key input is not accepted unless the four-digit password is input. [0004] For this reason, the key lock function not only prevents a key from being pressed by mistake, but also prevents a person from using the telephone when the portable telephone is lost. [0005] However, the user has to input a four-digit personal identification number when making a call to the other party, which is very troublesome. Even if the user wants to register a one-digit password (for example, 1), the user must key in 0001 at a time if the system is configured to register a four-digit password. Furthermore, a password is usually represented only by a numeral, and a password that is represented only by a number may be unlocked by accident if another person tries a plurality of key inputs a plurality of times. SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and a communication apparatus according to a first aspect of the present invention has an input means having at least one key other than a numeric keypad. Registration means for registering the order of pressing by keys other than the numeric keypad, and control means, the control means,
During the key lock state in which the input from the input unit is invalidated, if it is determined that there is a key press in a pressing order by a key other than the numeric keypad registered by the registration unit, the key lock state is released. I do. According to a second aspect of the present invention, there is provided a communication apparatus comprising: input means having at least a numeric keypad and one or more keys other than the numeric keypad; registration means for registering a numeric keypad and a pressing order by keys other than the numeric keypad; When the control unit determines that there is a key press in the order of pressing by the numeric keypad registered by the registration unit and a key other than the numeric keypad during the key lock state in which the input from the input unit is invalidated The key lock state is released. According to a third aspect of the present invention, there is provided a communication device comprising: an input unit having at least a numeric keypad and at least one key other than the numeric keypad; a registering unit for registering a pressing order of keys including keys other than the numeric keypad; Control means,
When the control unit determines that there is a key input in a pressing order different from the pressing order by the numeric keypad registered by the registration unit and a key other than the numeric keypad during the key lock state in which the input from the input unit is invalidated. And displaying a message instructing the user to input a password on the display means. According to a fourth aspect of the present invention, there is provided the communication device, wherein input means having at least a numeric keypad and at least one key other than the numeric keypad, types of keys including keys other than the numeric keypad to be pressed, and an order in which the keys are pressed are registered. Registration means for storing, and storage means for storing information indicating the type of key to be pressed and the order of pressing the keys registered by the registration means,
A notification unit, and a control unit, wherein the control unit determines that there is an input from the input unit using a ten-key and a key other than the ten-key during a key lock state in which a key input from the input unit is invalidated. Then, it is determined whether or not the type of the input key and the order in which the keys are pressed match the type of the key to be pressed and the order in which the keys are pressed stored in the storage unit. If it is determined, the key lock state is released, and thereafter, processing according to the key input from the input means is performed.
The notifying unit notifies that the key operation is not accepted and keeps the key locked state. FIG. 1 is a block diagram of a communication apparatus which is an embodiment of the present invention. The control unit 100 includes, for example, a ROM (Read
First storage unit 110 consisting of Only Memory
And controls the circuits described below based on the system program stored in. The transmission / reception unit 120 is connected to the antenna 121 and transmits and receives radio signals. An input unit 130 includes a numeric keypad, a call key, an off key, a function key, a cursor movement key for moving a cursor displayed on the display unit 150 described later, a key for instructing creation of mail and start of transmission / reception, and the like. Having. The second storage section 140 stores telephone number data,
Information indicating whether the apparatus is in the key lock state (key lock flag), the type of key for releasing the key lock state when the apparatus is key locked, and information indicating the pressing order of the key are stored. The form of storing data in the second storage section 140 is, for example, as shown in FIG. In FIG. 3, key types can be stored in association with each address, and the number of keys to be input up to the number of addresses (five in this embodiment, but the number of addresses may be more or less). The type can be registered. The address indicates the order of keys to be input in order from the first,
For example, in the example of FIG. 3, the first key to be input is the call key stored at address 1 and the second key to be input is the numeric keypad "1" stored at address 2. . The pointer points to the address of the next key to be entered, and when the keys to be entered are entered in the correct order, the pointer moves from address 1 to address 2,
Instruct to 3 in order. Although the telephone number data is also stored in another area of the second storage unit, since it is not directly related to this embodiment,
Description is omitted. The display unit 150 instructs to input a password when a key different from the type of the key stored in the second storage unit 140 is pressed in the key lock state. , Please enter your PIN)
Is displayed. The message "Please enter your password" is displayed when someone other than the user tries to use the communication device. This is a display for prompting the user to try to enter a password a plurality of times to cancel. However, since the key lock cannot be released unless a key operation (including keys other than the numeric keypad) is performed, the key lock is not released as long as a person other than the user performs the input operation of the personal identification number. . The speaker 160 is connected to the amplifier 165 and not only emits a ringing tone when an incoming call is received, but also when a key different from the key type stored in the second storage section 140 is pressed in the key locked state. A warning sound is output to Next, the operation of the present embodiment will be described below. FIG. 2 is a flowchart showing the operation of the apparatus of the present embodiment. In step S1, if control unit 100 determines that there is an input from input unit 130 to instruct to lock the key, the process proceeds to step S4; otherwise, the process proceeds to step S2. . In step S2, when detecting a signal indicating a key input from input unit 130, control unit 100 proceeds to step S3, and otherwise returns to step S1. In step S3, the control unit 100 performs a process (for example, a process corresponding to the key input in step S2).
Mail creation, telephone directory search, etc.), and return to step S1. In step S4, the control unit 100 performs a key operation procedure registration operation for releasing the key lock. Specifically, control unit 100 causes display unit 150 to display a display (for example, key lock release procedure input) indicating that an operation procedure for key lock release is to be input, and detects key press from input unit 130. Then, data indicating the type of the pressed key and the procedure of pressing the key is stored in the second storage unit 140.
For example, when the input unit 130 detects a signal indicating that the call key and the subsequent numeric keypad “1” is pressed, a call is made to the first address of the area for storing the pressing procedure of the second storage unit 140 as shown in FIG. Information indicating that the numeric keypad "1" has been pressed is stored in the second address of the key. or,
The control unit 100 turns on the key lock flag stored in the second storage unit 140 (sets the flag to 1), and sets the address pointer stored in the second storage unit 140 to address 1. In the following S5 step, the control unit 100
If it is determined that a key is pressed from the input unit 130, the process proceeds to S6.
Proceed to step. In step S6, the control unit 100 determines in step S5 that the key information input from the input unit 130 is the n-th (n is an integer) address pointed to by the address pointer of the second storage unit 140. If it is determined that the information is stored in step S9, the process proceeds to step S9; otherwise, the process proceeds to step S7. For example, the control unit 10
In step S4, when the press of the call key and the subsequent numeric keypad "0" are registered, and the press of the call key is detected in the subsequent step S5, the address pointer of the second storage unit 140 is stored in step S6. It is determined whether or not the information (call key) stored at the first address indicated by coincides with the address.
9. Process step S11, and in step S5,
If it is determined that the numeric keypad "1" has been pressed, in step S6, the key (numerical key "1") pressed in step S5 and the second address indicated by the address pointer of the second storage unit 140 are stored. It is determined whether or not the information (the numeric keypad “1”) matches. In step S7, the control unit 100 outputs a beep sound from the speaker 160 to notify the user that the key is not to be pressed, and causes the display unit 150 to display, for example, enter a password. , The process proceeds to step S8. In step S8, the controller 100 sets the second
The address pointer stored in the storage unit 140 is designated to address 1, and the process returns to step S5. In step S9, when the control unit 100 determines that the address indicated by the address pointer is the last address where the type of key to be input is stored,
It is determined that a key input for releasing the key lock has been performed, and S
The process proceeds to step S10. If it is determined that the address is not the last address, the process proceeds to step S11. In step S10, the control unit 100 turns off the key lock flag (flag = 0), releases the key lock state, and returns to step S1. In step S11, the control unit 100 sets the address pointer stored in the second storage unit 140 to 1
The value is incremented, and the process returns to step S5. As described above, the apparatus of this embodiment is configured to register the key pressing procedure instead of the key lock password, so that it is possible not only to prevent another person from knowing the key lock releasing method, The key lock can be easily released without inputting a multiple-digit personal identification number. When a key different from the registered key pressing procedure is pressed in the key locked state, for example, "Please input a password" is displayed. When trying to use the password, others assume that the user cannot use the device without inputting the password, and try to input the password multiple times to release the key lock. For this reason, the key lock state is not released as long as another person is trying to input a password using only the numeric keypad. In this embodiment, the present invention is applied to a portable telephone device. However, a PHS (Personal Handyp) is used.
For example, the present invention can be similarly applied to another communication device such as a phone system. In this embodiment, for example, the key lock cannot be released unless a call key other than the numeric keypad is pressed. However, keys other than the call key, such as speed dial keys and function keys, may be combined. . Further, in this embodiment, the key is locked immediately after the key is registered. However, the key registration operation and the key lock setting operation may be separated. In addition, in this embodiment, the ten keys and the pressing order by keys other than the ten keys are registered, and the key lock state is released if there is a key input in the registered pressing order. The order in which the keys are pressed may be registered, and if a key other than the registered numeric keypad is pressed, the key lock state may be released. According to the present invention, the key lock can be easily released by the user, and the key lock can be prevented from being easily released by another person.
