    摘要: A method of forming and attaching individual key tops to the key stems of a multi-key keyboard wherein each key top is formed of contrasting colors such that the key top indicia is clearly visually recognizable while also providing each key top with a bar code indicia for enabling a bar code reader to select a desired key top from among a random group of key tops and for enabling a transfer mechanism to selectably orient the selected key top with respect to a key stem for automatic attachment thereto.

    摘要: A data key assembly having a keystem which is movably mounted in a housing. The housing also supports a flat diaphragm switch with an actuating surface which is oriented parallel to the direction of motion of the keystem. An actuating spring is coupled to the side of the keystem by a lot-motion connection which provides hysteresis in the key action, and the spring slides over the actuating surface to close the switch when the keystem is depressed.

    摘要: A keyboard for a typwriter and the like, has at least one elongated key, elements for swivellably supporting the key and including at least one substantially U-shaped bracket with a U-bottom, two U-legs connected with opposite ends of the U-bottom, and two projections extending from free ends of the U-legs and parallel to the U-bottom, such that the key is swivellably supported on the projections with a play. At least two stationary swivel bearings swivellably support the U-bottom of the bracket. At least one of the bracket and the key is supported in a bearing point in a noise-dampening manner.

    摘要: A contact key for use in a keyboard arrangement is disclosed wherein one contact extends through a circuit board and a second contact comprises a curved plate or dome spring is positioned on one side of the circuit board and is depressable so that the center thereof can come in contact with the first contact to complete a circuit. In one form of the invention the first contact comrpsies a rivet while in another form it comprises a plated-through hole to the back of the circuit board. The second contact can include a dimple at the center thereof which comes in contact with the first contact when the plate is depressed. A plurality of these first contact members are placed in a circuit board and the second contacts can be supported by a conductive support, such as a shim or plated support having apertures corresponding to the position of the first contacts. If the contact support is in the form of the shim, it can comprise a plurality of sections interconnected by frangible tabs which are broken during assembly to separate the sections, the tabs being bent through holes in the circuit board and crimped against the back side to hold the shim in place and to provide connections for the respective sections to appropriate circuitry. In an embodiment having a plated contact support, the support can be provided with one or more raised bosses to support the contact plate above the first contact.

    摘要: A keyboard encoder comprises a set of keys. Each key is in juxtaposition with one or more field-responsive elements associated with that key, the outputs of the field-responsive elements being conveyed to output terminals of the encoder. Actuation of a key alters the field to which the elements associated therewith respond. The number of elements associated with each key and the connections of these elements to the output terminals correspond to the output code for the character represented by the key. Consequently, the responses of the fieldresponsive elements to actuation of a key provide a directly encoded representation of the corresponding character at the output terminals. Also disclosed is an elongated switch bar in which contact is readily made even though the switch bar is depressed at either of the two ends thereof.
