Title: System Design for a Digital Electronic Sign Board

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a system design for a digital electronic sign board, and more particularly, to a system design in which a computer module is removable and attached to a main circuit board so as to pull out and insert the computer module from or into the digital electronic sign board. 
     2. Description of the Prior Art 
     Nowadays there are various digital electronic sign boards installed in public areas for providing information or posting advertisements; however, when a content provider wants to change or add information contents, it is necessary to attach a computer externally to update the displaying contents or advertisements. Although the above mentioned technique can satisfy the purpose of displaying information or advertisements, there are a few issues presented in its usage:
         1. When a computer equipped on the digital electronic sign board needs maintenance or information update, it is necessary to disassemble the whole digital electronic sign board to retrieve the computer for maintenance or information update. It often takes a long time and lot of efforts for the maintenance; therefore it is inconvenient and laborious for maintenance workers;   2. When the computer is attached to the back side of the digital electronic sign board, it would increase the whole volume and make it difficult to install the digital electronic sign board;   3. There is a certain limitation to the volume of the computer when it is to be attached to the digital electronic sign board, making it inconvenient for computer upgrades.       

     Therefore, the traditional system design for a electronic sign board presents several shortcomings to be overcome. 
     In view of the above-described deficiencies of the traditional system design for a electronic sign board, after years of constant efforts in research, the inventor of this invention has consequently developed and proposed a new system design for a digital electronic sign board in the present invention. 
     SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a system design for a digital electronic sign board in which a computer module is removable and attached to a main circuit board. As a result, when a maintenance worker needs to perform maintenance on the computer module, he or she can conveniently pull out the computer module from the digital electronic sign board and insert the computer module back to the digital electronic sign board after maintenance is done so as to improve the efficiency and quality of maintenance. 
     It is another object of the present invention to provide a system design for a digital electronic sign board in which the computer module is removable and attached to the main circuit board; therefore the computer module can be conveniently disposed with a slot for inserting a graphics card, a video card, or a DIV output card to enhance versatile capabilities. 
     It is another object of the present invention to provide a system design for a digital electronic sign board, the system design can improve the efficiency and quality of maintenance, reduce manufacturing costs, simplify the system complexity, facilitate system upgrade and also provide small volume with wide application range. 
     The present invention discloses a system design for a digital electronic sign board comprising a main circuit module, an adapter module and a computer module; wherein the adapter module is disposed between the main circuit module and the computer module. The main circuit module and the adapter module are fixed in the digital electronic sign board. The computer module is externally inserted into the digital electronic sign board; therefore the computer module and the main circuit module are electrically connected through the adapter module. 
     These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying Drawings.
