Abstract: A keyboard includes a plurality of keys, and a keyframe into which the plurality of keys are assembled. Each of the keys includes: i) a plunger on which a character is printed, and ii) a keycap made of a transparent material. The keycap covers at least a portion of a top of the plunger.

Abstract: A label having an identifier 41L is applied to the upper left corner of the key top of each character key in a left hand region of a keyboard device. A label having an identifier 41R is applied to the upper right corner of the key top of each character key in a right hand region. The identifier 41L is a mark of a reversed L shape and the identifier 41R is a mark of a mirror image pattern of the identifier 41L. Further, different colors are applied to the identifiers 41L and 41R depending on regions for individual fingers. As a consequence, the identifiers 41L and 41R have a function to visually display information representing which hand is to be used to press a key and information representing which finger is to be used to press the key. The keyboard device enables a user to naturally understand the arrangement of the keys and the use of the fingers.

Application of a protective layer to the front side of the support plate from which the material was removed. A function symbol is provided on the button such that it can be backlit. It is engraved in a fine line width providing a sharp optical definition erosion, mechanical engraving.

Abstract: Keyboard keys using a marked elastic dome and the fabrication method thereof. The method for fabricating elastic domes first includes providing a mold having a plurality of mold cavities with a markable surface. Next, a plurality of different marks is formed on the markable surface of each of the mold cavities. An elastic membrane with a plurality of marked elastic domes is formed by the mold. The marks on the elastic domes represent the position with respect to the mold cavities on the mold and the parameters of fabricating the elastic membrane. Finally, the marked elastic domes are separated from the elastic membrane and used in keys of a keyboard.

Abstract: The invention relates to a keyboard arrangement and a method for detecting an input character. In particular the invention relates to a method and arrangement for reducing the number of keys in a QWERTY-keyboard (20) or the like. One idea of the invention is to provide keys (210) with several characters and to provide alternative ways to press the key for entering a selected one of the alternative characters. The keys are preferably triangular or have three arms, and one of three characters can be selected by pressing the corresponding corner/arm of the key. The keyboard may preferably be formed of interlaced rows of keys. Linguistic disambiguation is advantageously used in addition to said mechanical disambiguation. The invention is well suited for mobile station keyboards.

Abstract: A key sheet comprising a key top, a translucent resin film, and a symbol layer. The key top is made of resin and has a top surface and a rear surface. The key top includes a gate corresponding section in a position corresponded to a gate of a mold for injecting resin to form the key top. The translucent resin film is provided over the key top. The symbol layer is disposed to associate with the top surface of the key top. The gate corresponding section is located to prevent that gate corresponding section from being viewed through the symbol layer.

Abstract: A device and method for implementing a key, in which a field applied to a layer comprising a material whose volume is responsive to the magnitude of field is altered at a specified position to create a key in said position; said field being one of the following: electric field, magnetic field, both of the above.

Abstract: The present invention relates to the uses of metallic light reflecting characters on computer key caps, providing reflections from natural external light sources, providing human beings a luminous reflection thus enhancing human beings abilities to see and read computer key cap characters on a standard QWERTY computer keyboard in low lighting.

Abstract: The present invention relates to a foldable keyboard, and more particularly, to a foldable keyboard adapted for a point stick and/or at least one hot key. Two or more keypad portions are hingably connected by a connection board on which a point stick or at least one hot key is disposed. When the keyboard is in a deployed configuration, the keypad portions slide along the keyboard plane to combine with the point stick or the hot keys so that a complete keyboard is formed. The connection board of the present invention may further include a circuit board to be electrically connected with each key and the point stick or the hot keys in order to receive and decode the signals from each key and the point stick or the hot keys.

Abstract: The present invention relates to a laminate key sheet wherein a key sheet of a resin film having a display section is bent into a same form as the top and side faces of each resin button in order to be integrated with the resin button and where a cut-out is formed between the resin buttons. A rubber elastic sheet and the resin film are connected together through an adhesive interposing between an area between resin buttons of the key sheet and the rubber elastic sheet.

Abstract: The improved structures of the push-button key of keyboard are characterized in that the upper housing panel of keyboard comprises a plurality of partitioned sections where the push-button keys are installed, and that a key barrel of a predetermined height is set up at the center of each of the partitioned sections. The barrel wall comprises two slide keys positioned correspondingly to two slide key seats of the push-button key. The hooking means are arranged in the partitioned section at a predetermined distance from the key barrel. The stability of up-and-down movement of the push-button key is ensured by virtue of a coordinated action of slide key and slide key seats. The hooking means serve to confine the movement of the push-button key and to prevent the push-button key from being detached easily.
