Abstract
The invention is to provide a multi-function erroneous contact protection structure for electronic device keyboards in which a minimum of one transparent cover is positioned at the lateral edge of at least one key switch on the case of an electronic device with one end of the said cover protruding from the said case at a height equal to or greater than that of the said key switches, the protruding cover structure of the case enabling the simultaneous touching of the said cover when the user strikes a said key switch, reminding the user that the said key switch is a critical key switch and thereby preventing erroneous contact with the said key switch.
Claims3
A multi-function erroneous contact protection structure for electronic device keyboards comprised of:
- at least one case having a display opening and plurality of key switch holes arrayed in even rows, wherein an installation hole is disposed at the edge of at least one key switch hole;
- a control circuit installed inside the said case that is utilized to govern the operations of an electronic device;
- a display screen mounted in the said display opening, the wiring of which is connected to the said control circuit;
- a plurality of key switches respectively positioned in the said key switch holes and projecting from the surface of the said case, enabling the locating of the said key switches and the generation of different alphanumeric characters and commands to the said control circuit following their depression;
- a transparent cover positioned in the said installation hole which protrudes from the surface of the said case at a height equal to or greater than that of the said key switches and, furthermore, a recess is formed in the bottom surface of the said cover;
- a light-emitting diode is situated inside the said recess at the said cover bottom surface, with the terminals of the said light-emitting diode connected to the said electronic device control circuit such that the said light-emitting diode is triggered by the operation of the said control circuit and its beam projected through the said cover.
