ABSTRACT:
A guard for protecting the keys of a keyboard from being untimely depressed, the guard is formed of a rigid material, such as an acrylic plastic, and contains an aperture(s) therethrough for accommodating the positioning of the keys therein, so as to avoid their being depressed other than when acted upon intentionally by a machine operator. The apertures may be in the form of a pair of slots extending the length of the guard and which are designed for accommodating at least a pair of rows of keys therein, with the guard containing a vinyl decal that is imprinted with indicia to indicate the function of the proximate keys upon depressing. The guard contains either one or more holes provided there through and into each a pin projecting from the keyboard may be inserted for providing proper positioning of the guard, or alternatively, stick angles may be provided at the corners of the guard to insure its reasonably stationary positioning upon the keyboard.
