This invention relates to a computer keyboard support, and more particularly to a computer keyboard support which is mainly installed on computer keyboards to offer more convenient computer work and improved work efficiency. 
     BACKGROUND OF THE INVENTION 
     In general, to load data of documents and/or manuscripts into a computer, the documents or manuscripts are placed in an appropriate place on the desk where the computers and keyboard are, and the operator performs computer operations while looking at the documents/manuscripts. However, such process of working has the following demerits. 
     Because the manuscripts are placed on the left or right side of the keyboard and monitor of computers, operators have to move their eyes often during the computer work, causing eye strains easily. This makes the use of computer inconvenient and causes the work efficiency to deteriorate. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to correct such existing disadvantages. In the present invention, as the manuscripts are placed directly above the computer keyboard, eye strain is reduced, working becomes more convenient and work efficiency is improved. 
     To satisfactorily achieve the above object, the device according to the present invention allows the paper holder board, installed directly to the upper side of keyboard, to move freely towards the front and back so that operator can see manuscripts in the most suitable direction and angle and, upon completion of work, the operator can pull the paper holder board to cover and protect the keyboard. 
     From above, it is ideal to make the paper holder board installed at the back of the support to move to the left or right and, at the front, a hand rest is installed so that operator can rest hands comfortably to ensure comfort and more efficient working environment. 
     To fix the paper board support which holds the paper holder board turning freely on the keyboard, brackets can be installed on the left and right side of the keyboard, connecting the paper board support with shaft-pins. 
     In addition, another example of an operation of a keyboard support according to the present invention includes the paper holder board having the keyboard support, which is made to turn freely and move to the left or right. Because the keyboard support described above has a fixed size of body, the keyboard used is also limited. 
     Accordingly, to use the keyboard support more flexibly in installing on keyboards, the keyboard support may be constructed in ##STR1## type which is equipped with the rear catch with the front catch installed, or in ##STR2## type so that the keyboard support can be used regardless of types or sizes of keyboards.
