Abstract

PURPOSE:To prevent an information setting error owing to key information on a misoperation in a user. CONSTITUTION:Key information for key locking inputted from a key input part 11 stops the transmission of key information to a control part 12 in a key locking control part 16 and it is stored in a storage part 13 as setting information. Then, the key locking control part 16 is prevented from transmitting information to the control part 12 even if key information is inputted, and the rewriting of setting stored information is unabled. Key locking by the rewriting of setting information is released by inputting prescribed key information to the control part 12 through the key locking control part 16, or by turning off a battery on/off switch 15.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device capable of locking and releasing valid / invalid setting information of key operation.

[0002]

2. Description of the Related Art FIG. 2 shows the configuration of a communication terminal device having no conventional key lock function.

In FIG. 2, reference numeral 1 is a key input unit for identifying key information that has been pressed. A control unit 2 controls storage of setting information which is input key information. Three
Is a storage unit that stores setting information. Reference numeral 4 denotes a battery, which supplies a voltage for storing the setting information stored in the storage unit 3.

A storage unit 3 and a key input unit 1 are connected to the control unit 2. Next, the operation of this configuration will be described.

In FIG. 2, setting information of key information obtained by operating the key input unit 1 is sent to the control unit 2. Control unit 2
Then, the setting information is rewritten based on this key information, and the setting information is stored in the storage unit 3. The setting information stored in the storage unit 3 is held by the battery 4.

[0006]

However, in the communication terminal device of the conventional example, if there are many items to be set from the panel keys constituting the key input unit 1, the setting is not easy.
Therefore, an erroneous operation is likely to occur at the time of re-setting after installation, and in this case, there is a problem that communication is disabled due to erroneous setting.

The present invention solves such a conventional problem, and an object of the present invention is to provide an excellent communication terminal device capable of preventing an information setting error due to key information of a user's erroneous operation.

[0008]

In order to achieve this object, a communication terminal device of the present invention comprises a setting information input means for inputting setting information by key operation, a setting information storage means for storing the setting information, The backup power supply connected to the setting information storage means and holding the stored setting information is turned on and off, and the voltage from the backup power supply is turned on and off, and the setting information stored in the setting information storage means is erased when turned off. And a key lock control means for controlling stop of rewriting of the setting information stored in the setting information storage means by inputting setting information of a predetermined key lock from the setting information input means, and a predetermined information from the setting information input means. Key release control means for controlling the rewriting of the setting information stored in the setting information storage means by inputting the setting information for releasing the key. Is shall.

[0009]

With such a structure, the communication terminal device of the present invention can be operated by inputting predetermined key information for key lock.
Since the rewriting of the stored setting information is stopped and the setting information is rewritten by turning off the voltage from the backup power supply or inputting the predetermined key information for releasing the key, the key information of the user's erroneous operation It is possible to prevent information setting error due to.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a communication terminal device of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of the embodiment. In FIG. 1, reference numeral 11 denotes a key input unit that identifies key information that has been pressed. A control unit 12 controls storage of setting information based on the input key information. 13 is a storage unit,
The setting information from the control unit 12 is stored. Reference numeral 14 denotes a battery, which supplies a voltage for storing the setting information stored in the storage unit 13. A battery on / off switch 15 switches the application of a voltage to the storage unit 13. Reference numeral 16 denotes a key lock control unit, which locks and unlocks the key lock, and when the key is locked, the control unit 1
Stop sending key information to 2.

The key input unit 11 includes a key lock control unit 16
The controller 12 is connected to the storage 13 and the key lock controller 16.

Next, the operation of this configuration will be described.
When key information is input from the key input unit 11 by a predetermined combination operation for key lock, the key lock control unit 16 stops sending the key information to the control unit 12.
The key information for this key lock is stored in the storage unit 13 as setting information through the key lock control unit 16.

As a result, even if the key information is input thereafter, the key lock control unit 16 outputs the key information to the control unit 12.
Stop sending to. Therefore, since the input key information is not sent to the control unit 12, the setting information stored in the storage unit 13 is not rewritten.

The key lock is released by rewriting the setting information by inputting predetermined key information or turning off the battery on / off switch 15.

To release the key lock by inputting predetermined key information, the key input unit 11 sends out key information by a predetermined combination operation for releasing the key lock. After that, the key lock control unit 16 sends the key information from the key input unit 11 to the control unit 12, and erases the setting information stored in the storage unit 13.

When the key lock is released by turning off the battery on / off switch 15, when the setting information in the storage unit 13 is erased by turning off the battery on / off switch 15 in the key lock state, the key lock is restored. It will be canceled. When the key lock is released by this operation, the setting information based on the key information input from the key input unit 11 again can be stored through the key lock control unit 16.

[0018]

As is apparent from the above description, the communication terminal device of the present invention stops the rewriting of the stored setting information by inputting the predetermined key information for the key lock, and the backup power source. Since the setting information is rewritten by turning off the voltage or inputting predetermined key information for releasing the key, it is possible to prevent the information setting error due to the key information which is erroneously operated by the user.
