Self-diagnosis Multifunction Expansion Keyboard

The present invention relates to a high-performance expansion keyboard, and more particularly, to a self-diagnostic type multifunction expansion keyboard that can control the functions of the computer main body by adopting a signal transmission system between the computer main body and the keyboard in both directions.

Generally, in the conventional keyboard, as illustrated in FIGS. 1 to 3, the keyboard 87 recognizes characters input to the keyboard 76 and letters inputted to the keyboard 76 in capital letters. A caps lock key 71 selected so as to be selected; a direction key portion 5 for indicating a moving direction of the cursor; and a number lock key 67 for setting a numeric key or a direction key on the direction key portion 5 to an active or inactive state; And, a scroll lock key 75 for turning on / off a function of moving the screen up and down, and status display means 81 for displaying the operation states of the number lock key 67, the cap lock key 71, and the scroll lock key 75; Equipped with.

In addition, the front of the computer main body case 1 has an A drive 6 for inserting a 5.25 diskette, a B drive 7 for inserting a 3.5 diskette, a CD ROM drive 9 for inserting a compact disk ROM, and the drive. A power switch 31 for applying power to a computer, a reset switch 35 for temporarily shutting off power supply, and a power display means 37 for displaying the operation of the power switch 31. ), A hard disk drive display means (33) for displaying the drive of the hard disk, and a turbo display means (4) for displaying the clock operation state of the central processing unit so as to quickly process the operation and work speed of the computer. Equipped.

The keyboard 87 is connected by a cable 501 to supply power to the keyboard through the keyboard connection port 99 provided on the rear surface of the computer main body 1. The power of the power supply 73 is also supplied to the A drive 6, the B drive 7 and the CD ROM drive 9.

However, the conventional keyboard configured as described above is composed of a unidirectional signal transmission system, and when the user presses the keyboard, it only plays the role of a simple input device for transmitting a signal to the computer main unit (main body). From now until the role and structure has not escaped from the fixed idea, and the conventional computer power switch 31 is to install a switch in the power supply in the interior of the main body case (1) to the front portion (8) In order to use the computer, the user could only supply power and cut off the power supply through the power switch 31 of the computer main body 1, so that the user should always keep the main body 1 close for power management. There was a problem.

However, in recent years, in order to solve the problems of the conventional keyboard, products that merely change the conventional keyboard have been developed and marketed by each keyboard manufacturer and some computer related vendors. It is a situation that does not deviate greatly from the stereotype.

In the first example, a keyboard locking key is added to a conventional keyboard to prevent an unexpected key press from the outside, and a small microphone and a headphone jack are built in to meet the multimedia era. Among them, the key for accessing the Internet is for its program users, and users using third-party programs cannot use it normally.

Second, add a HOLD LOCK key to restrict the use of other users, and shorten the calculation time when using it as a calculator for icon minimization keys, job completion keys, and banks in keeping with the Windows 95 operating system. In order to add '00' key or '000' key, these functions are already applied to other products (keyboards such as terminals, not general computer keyboards). there was.

Thirdly, the 'IC security keyboard' with embedded IC chip for decryption is introduced, but this is to maintain security by limiting the use range of the computer through personal ID card. There were problems such as a lot of facility investment, time, high cost, and scope of use because of the management control.

As a fourth example, a wireless keyboard for Internet TV has been released to prepare for the future of Internet TV and the wireless era, but this has been a problem that its implementation and stability are still opaque.

As such, even though the keyboard is the latest development, the development focus is simply on adding a shape or a use key to the past model, so that the user is faced with a user-friendly keyboard at an additional cost. There is a problem that can not see, and also the user who learns the computer through the keyboard for the first time has a problem that it is difficult to easily access the computer due to the distributed working environment.

The present invention has been made in view of the above various problems, and an object of the present invention is to adopt a signal transmission system between a computer main body and a keyboard in both directions, and a self-diagnostic type multifunction capable of controlling a function of the computer main body with a single keyboard. To provide an expansion keyboard.

Another object of the present invention is to provide an easy-to-use self-diagnostic multifunction expansion keyboard that can fully accommodate the needs of the user.

Still another object of the present invention is to provide a self-diagnostic type multifunctional expansion keyboard so that a user can use the computer more conveniently by controlling all functions of the computer body with only one keyboard regardless of the position of the computer body.

In order to achieve the above object, the self-diagnostic type multifunction expansion keyboard of the present invention is a conventional keyboard having a dial, comprising: a power switch for supplying power to a computer, a reset switch for temporarily shutting off power supplied to the computer, The screen protection program is executed by the keyboard control program stored in the memory device, and the system is protected by using the keyboard password setting function and the power-off function provided on the screen protection program. A system temporary lock means to store data and to emit a beep, a telephone drive means to receive an incoming call through a hardware telephone circuit / communication modem while the user is using the computer, and to make a call to the other party; , A port for connecting a mouse and a user Note A user-defined extension key that adds a specific function according to a user's specific request to quickly execute a program according to a keyboard control program stored in a memory device, and an Internet expansion keyboard connection port for connecting an Internet-only keyboard to search the Internet. A dedicated joystick port for connecting a dedicated joystick, a voice input / output terminal for inputting / outputting sound to and from the sound card through an expansion keyboard control panel, a voice memory button for memorizing user's voice, and music Music button to activate CD playing, sentence voice reading function button to listen to user's searched contents, volume control to decrease / increase the volume output from sound card and to temporarily mute the volume. Calculations for calculating the means, the signal input to the direction keys and the numeric keypad It is characterized in that it is provided with a function button and a display means for displaying the operating state of the system so as to check the state of the system during the operation.
