Abstract: A data input and/or operator control system, particularly a keypad, also a POS keypad, having a lower portion and an upper portion and also at least one printed circuit board and at least one retaining plate. Inside, one or more protective mat(s) made of an elastic material is/are preferably adhesively bonded to the printed circuit board. In this protective mat, the components of the printed circuit board are recessed to as small an extent as possible and air ducts are incorporated in order to ensure that the keys are ventilated in relation to one another.

Abstract: A data entry and/or operating system, particularly a keyboard, also a POS keyboard, includes a lower part and an upper part as well as at least one circuit board and at least one retainer plate, the retainer plate lying on the lower part. One or more bushings are integrated for the purpose of connecting the circuit board to the retainer plate. The upper part is formed from a rubber mat having keys, and the stability of the keyboard is assured by the circuit board, bushing and metal retainer sheet. The lower part is connected to the upper part in a sealed manner.

Abstract: A keyboard is provided as a peripheral device for a computer unit with a key field and an associated housing, whereby an extension is attached to the housing. The keyboard includes at least one reading device being accommodated in the extension for the contactless reading of data stored on ID cards or access cards or documents.

Abstract: A keyboard is provided with at least one keypad, a housing, and at least one USB port, wherein the USB port is located behind an opening in a top of the housing and the opening is at least partially closed by a dirt and/or dust protector.

Abstract: A one-piece keyboard housing in a simple but compact manner is provided by using an internal gas pressure injection molding process (air mold process). With this process, the keyboard housing can be formed as a one-piece molded part with recesses and cavities. The cavity serves to reduce weight, and the process itself improves stability within the keyboard housing. The molded part is formed of a traylike first housing shell, in which a keypad can be mounted, and a second housing shell with recesses that joins the first housing shell in an n-shape.

Abstract: A keyboard having a housing, which is designed as one piece and wherein a top open housing shell is designed in conjunction with a keypad such that the top shell is traylike and is attached within the housing at an angle. A bottom base of the top open housing shell forms a bottom open housing shell. The bottom open housing shell has at least one recess provided for the installation of a card reader.

Abstract: A keyboard housing is built of one piece of material, with the keyboard housing being formed of an upper housing shell and a joining S-shaped lower housing shell. In this regard, the keyboard housing is preferably of resinous plastic. The keypad and, for example, the keyboard electronic circuitry are contained in the upper housing shell, with the auxiliary components being the lower housing shell.

Abstract: It is proposed to produce a one-piece keyboard housing (2) in a simple but compact manner, and to use the internal gas pressure injection molding process (air mold process) by preference to this end. With this process, the keyboard housing (2) can be executed as a one-piece molded part with recesses (5, 6, 6.1) and cavities (7). The cavity (7) serves to reduce weight, and the process itself improves stability within the keyboard housing (2).

Abstract: The invention concerns a keyboard, preferably for cashier registers.

Abstract: A large key covering several small key fields of a keyboard has a bearing fork projection (9), lever arms (10 and 11) of which each have an bearing pin (12) that engages a grip slot located in each side of an adjacent guide bush pair (14), with a key ram (5) of the large key ram including a clip collar (16) which, when the large key is pivoted to extend the key ram into a guide bush (6) of the guide body (3), snaps over a protrusion ledge (15) in the guide bush. The large key provides an arrangement that is easy to install, is structured as a single piece, and allows for simple verification of assembly; unlike known large keys covering several small key fields which comprise several parts and are difficult to mount.

Abstract: A control unit (1) for switching and controlling functions (6) of household appliances has a continuous control surface (2) with operational areas (3) and a printed film (5). Several piezosensors (4) are arranged on a back of a plate forming the control surface (2), connected firmly and rigidly to the plate. The piezosensors (4) can be located in a film packet (9), for example, through which the piezosensors (4) are electrically connected to a processor (12). Through an offset arrangement of the piezosensors (4) in a matrix pattern direct illumination or back lighting of the printed film (5) can be achieved, thereby improving an operator's visual recognition while permitting accurate recognition of a function by the processor (12). An input filter (15) prevents operator error due to unintentional actuation of the control unit.

Abstract: By applying pressure created by a forced guidance of a sled (11) to contact springs (12-19) carried by the sled, a reduced contact friction upon insertion, as well as upon removal, of a chip card (3) results. This forced guidance is achieved by having a cut-out (7) in a circuit board (5) in which the sled is shoved by the inserted card to be guided by double slot guides (9)on each side of the sled.
