    Abstract: Keyboard for the control box (11) of an electric apparatus comprising a sheet (1) which forms a plurality of contactors (2) each projecting from the sheet through a blister (3) which is elastically deformable and which acts as a spring, said contactors (2) being provided with bearing keys (8) and contact pads (5) intended to come into contact with a printed circuit (12) arranged under the sheet (1) of contactors when a pressure is exerted on the keys. This keyboard is remarkable in that at least certain of said contactors (2) are provided with stubs (4) arranged opposite the contact pads (5) and which are intended to be force nested into corresponding housings provided in the bearing keys (8).

    Abstract: A structure of a contact rubber used for various kinds of electronic appliances, and to preventing an oily substance which has penetrated into the contact rubber from the outside, or which is contained in the same rubber from coming out to the surface of a conductive portion of said rubber to thereby inhibit an increase in the contact resistance value of the conductive portion. The conductive portion (2) is formed on a key top (1), which is molded from an insulating rubber into the shape of a dome, via jn oil-proof portion (3) formed of a layer of an oil-proof rubber or a resin film.

    Abstract: An improved, low cost, high speed keyboard encoding device is provided which develops directly encoded, valid and reliable multi-bit output signals and overcomes problems associated with tolerance errors and adverse environmental and usage conditions (e.g., manufacturing errors, dust, wear). The preferred encoding device includes a plurality of juxtaposed, flexible conductive strands or wires each having a number of axially spaced impact zones along the length thereof which are either insulated or electrically conductive; corresponding zones on the separate wires are operably aligned to cooperatively define a series of spaced impact zone sets each made up of a unique pattern of conductive and insulated zones. An electrically conductive, rubber-like resilient pad having a series of ridge-like elongated members respectively aligned with corre- s pon d ing impact zone sets is also provided which is designed for impact-shifting of the members into momentary contact with the associated zone sets, whereby electrical contact is made between the ridge members and the conductive impact zones of the set. The resulting circuit making and current flow directly generates a momentary, unique, digitalized output signal without the need for conventional encoding electronic circuitry. The device is particularly suited for use in an impact-type keyboard where, upon depression of each key, an associated resilient element is shifted, released, and allowed to overtravel its rest position and momentarily strike the encoding device at a location for shifting the appropriate pad ridge into contact with the adjacent impact zone set.
