Description

Keyboard with lock function

The present invention relates to a keyboard, and more particularly, to a keyboard having a lock function that blocks the operation of an external device connected to the keyboard by a user blocking the operation of the keyboard.

In recent years, with the advent of information and service society and the spread of computers, it is possible to quickly and accurately send and receive various types of information and correspondence through computers at home, as well as enjoy shopping, entertainment, and games.

However, on the Internet using computers, there is a lot of useful information as well as a lot of harmful information, and a lot of information can be easily accessed by anyone.

Due to this, people become addicted to the Internet even with information that can be easily accessed by anyone, and it is common for them to fail to do their jobs.

Especially for young children and students, they are unable to lead a normal life and study, causing serious problems both at home and socially.

Therefore, it is also necessary to prevent young children from using the computer for too long for gaming or other reasons.

In addition, there is a possibility that a third party who is not the user of the computer can easily access information inside the computer while the user is away from work for a short time while working on the computer.

For this reason, in the prior art, a blocking program that blocks the operation of a computer to prevent unnecessary and harmful information and entertainment or games for young children or students may be installed in the general home to restrict the use of the computer to students or young children.

In addition, a fingerprint recognition device that only the user can operate the computer can be installed in order to keep the internal information of the computer secure while the computer is temporarily away from work, so that the computer cannot be operated except by the user.

However, if the parents do not have computer knowledge, there is a problem that it is difficult to install a program to block harmful information or games, so that the operation of the computer cannot be easily blocked from children or students.

In addition, the fingerprint recognition device has an effect of blocking access to information inside the computer or to young children or students at home, but there is a problem in that an expensive fingerprint recognition device must be separately installed.

Korea Public Utility Model Publication No. 1999-0033900 (1999. 08. 16. Announcement)

Therefore, the present invention is to solve the problems of the prior art, and by providing a lock key on the keyboard without installing a separate locking device, a lock function that allows the user to easily block the operation of the keyboard and block the operation of the computer connected to the keyboard It is to provide a keyboard with

The control unit 90 is located inside the keyboard body 10 , and is connected to the lock key 31 , the first input key 33 , the second input key 35 , the connection unit 50 , and the screen display unit 70 . .

The control unit 90 sends the information output from the first input key 33 and the second input key 35 through the cable 53 to the external device 150 and receives the information output from the external device 150 . can

When the control unit 90 receives the operation blocking signal from the lock key 31 , the key signal output from the first input key 33 and the second input key 35 to the external device 150 connected to the keyboard body 10 . and blocks the reception of a signal output from the external device 150 .

At this time, the control unit 90 blocks the key signals output from the first input key 33 and the second input key 35 to the external device 150, while the first input key 33 and the second input key ( 35) may be displayed on the screen display unit 70 .

Here, the driving of the screen display unit 70 may be operated by power input through the cable 53 or by inserting a separate battery.

The control unit 90 may further include a memory for storing passwords and operating time. The control unit 90 may receive the key signal sent from the first input key 33 and the second input key 35 to store the operating time and password of the keyboard body 10 in the memory.

As the memory, volatile memory (RAM) and nonvolatile memory (ROM) or EEPROM (Electrically Erasable PROM) may be used. The operating time and password stored in the memory can be set so that the stored value is maintained even when the power of the keyboard main body 10 is cut off.

The control unit 90 may display the operating time and the remaining operating time through the screen display unit 70 . The control unit 90 may display an operation blocking notice message on the screen display unit 70 10 to 20 minutes before the operation is blocked.

The control unit 90 is equipped with an operation time setting mode, a password setting mode, and a password input mode function to set an operation blocking, and when the * key is pressed for 2-3 seconds in the operation blocked state of the keyboard body 10, the screen display unit 70 Operation time setting mode and password setting mode can be displayed to appear.

Here, for the convenience of the setting mode, a menu key 36 in the form of a button and a cancel key 37 may be further included on the upper surface of the keyboard body 10, and the controller 90 presses the menu key 36 By receiving the signal, the operation time setting mode and password setting mode are displayed on the screen display unit 70, and when the cancel key 37 is pressed, the signal is received and displayed on the screen display unit 70 as the previous step or password input mode. .

When the menu key 36 and the cancel key 37 are installed on the keyboard body 10, the control unit 90 sends the first input key ( 33) and the key signal output from the second input key 35 are blocked, and the key signals of the first input key 33, the second input key 35, the menu key 36, and the cancel key 37 are displayed on the screen display unit. (70) can be indicated.

In order to set the operating time, the control unit 90 displays the set operating time on the screen display unit 70 when the operating time is input using the input keys 33 and 35 in the operating time setting mode, and presses the * key for 2-3 seconds. Long press to save.

When the pre-stored operating time is exceeded, the control unit 90 generates an operation blocking signal of the keyboard body 10 to block the operation of the keyboard body 10, and the password input mode is displayed on the screen display unit 70 .

In addition, when an operation blocking signal is generated by pressing the lock key 31 , the control unit 90 blocks the operation of the keyboard body 10 , and displays the password input mode on the screen display unit 70 .

The control unit 90 can check the input key value through the screen display unit 70 when a key value is input using the first input key 33 and the second input key 35 in the password setting mode for password setting, After entering the , key value, you can set the password to be saved by pressing and holding the * key for 2-3 seconds.

The password may be made by mixing letters, numbers, special symbols, etc. using the first input key 33 and the second input key 35 , or may be made of simply numbers using the first input key 33 . .

Since a method of inputting and storing a password may be variously modified, other examples will be omitted.

When the control unit 90 receives the operation blocking signal of the lock key 31, the screen display unit 70 displays the password input mode.

The control unit 90 receives the key values output from the first input key 33 and the second input key 35 in the password input mode, determines whether the input key value matches the pre-stored password, and generates an operation signal if they match to release the blocking operation of the keyboard body 10 .

When the input key value does not match the pre-stored password, the control unit 90 maintains the password input mode on the screen display unit 70 to re-enter the key value.

When the operation block is released, the control unit 90 may send the information output from the first input key 33 and the second input key 35 to the external device 150 through the cable 53 again, and the external device 150 ) can receive the output information.

The keyboard 100 according to the first embodiment of the present invention blocks the operation of the keyboard body 10 by a simple operation of pressing the lock key 31 to easily limit the use of the external device 150 connected to the keyboard 100 can do.
