An improved opaque computer keyboard cover (10) which covers only the three- or four alpha-numeric rows of the keyboard (12). Function and format keys (12) are not covered which provides a one-size-fits-all design. This configuration eliminates the need to order from 3000 various keyboard cover sizes. This cover is for use in keyboarding instruction and prevents peeking to accelerate user memorization. This cover can also be imprinted with a language option layout or Dvorak keyboard layout thus fully conforming the keyboard layout to one of the 60 or so languages available in the computer operating system keyboard preference options.

A calculator which generally possesses a flat, compact and portable housing construction, and which includes a calculator lid mechanism which pivots a flat cover of the calculator in a predetermined controlled manner between a first position causing the flat cover to form a lid which overlies a calculator display, and a second operational position in which the cover is pivoted towards the rear of the calculator so as to form a stand for tilting the calculator into an upwardly inclined ergonomic position relative to a horizontal support surface during intended use thereof. Upon the actuation of a switch, a release mechanism enables the lid to be pivoted rearwardly in a controlled damped manner about a hinge connection, which articulates the lid to the calculator housing, under the urging of a torsion spring and damping drum arrangement constituting the lid mechanism located within a tubular bore within the hinge portion of the lid structure into an essentially perpendicular orientation relative to the rear surface of the calculator housing so as to form the stand for tiltingly support the calculator when positioned on a horizontal surface.

The specification and drawings present a new method and apparatus for a touch actuation in an electronic device using a general purpose input board.

Disclosed herein is a light guide plate for keypad backlight panels, which is mounted at the rear of a keypad having numerals or characters printed thereon for supplying light emitted from a light source mounted at one side of the keypad to the keypad. The light guide plate is made of polycarbonate and is provided at the rear surface thereof with a concave-convex pattern, the density of which is increased as pattern elements of the pattern become more distant from the light source, such that light emitted from the light source is reflected and is uniformly supplied to the keypad, the pattern being formed on the light guide plate by hot stamping, injection molding, or micro blasting. The density of the pattern is adjusted by adjusting the distance between the pattern elements of the pattern or by adjusting the size of the pattern elements of the pattern. Consequently, it is possible to manufacture a keypad module in a slim structure or a curved structure. It is also possible to manufacture a keypad module that is capable of uniformly supplying light.
