The buttons of the current notebook computer keyboard are all _ with thin buttons. (4) Riding «Main (4) in the word key (4) between the bottom plate group, and the bridge-type bridge structure, but the thin bridge type keyboard structure of the conventional notebook computer has the advantages of ultra-thin size, light weight and precise operation. However, the keyboard itself does not provide a light-transmitting structure design for auxiliary illumination, so that the keyboard can only be operated in a place with bright light, and cannot be operated in a dark place, causing inconvenience in its operation on special occasions. Therefore, the applicant company has developed and applied for approval: the national patent "light guide plate and backlight module of the illuminated keyboard" (patent certificate number: M write 689) patent case and the US patent U08, 792 patent case, Although these patents have a light guiding structure of a keyboard, they do not have a design that produces uniform light transmission between the buttons. For the thin multi-layer stacking components in the keyboard (for example, a thin film circuit board, a spacer insulating board, a light guiding film, etc.), they are assembled in an adhesive manner, and it is difficult to assemble and position and each thin component The 4 M394524 actually caused the shortcomings of the keyboard assembly structure and assembly efficiency to overcome the shortcomings of the sticky treatment; in view of the fact that the creator of this I case has been actively researching and improving with years of experience in the manufacture and design of computer keyboards. After many physical sample production and testing' and then specifically improve the above shortcomings of the conventional computer keyboard, the creation is finally completed. [New content]
