The present disclosure provides a control device with which it is possible to easily customize an assignment of functions to an operation unit. The control device includes: an output unit that outputs a signal for prompting an electronic device to execute a predetermined operation; a function switch unit that includes a plurality of switches each having a contactor formed such that at least a portion of the contactor is elastically displaceable in a predetermined direction; and a label body that has a display part and a protruding part protruding from the display part, the label body being mounted in a state where the protruding part is inserted into a hole in a housing and the display part is positioned on an outside of the housing. The protruding part of the label body determines a combination of open or closed states of the plurality of switches. The predetermined operation is determined according to the combination.

Die Erfindung betrifft ein sensierendes Flächenelement,

das eine Sensoranordnung (8) aus mehreren Sensoreinheiten (9) aufweist, wobei die Sensoreinheiten (9) jeweils mindestens einen taktilen Schalter aufweisen und bei Aktivierung ihres Schalters Signale ausgeben.

Erfindungsgemäß ist vorgesehen, dass

die Sensoreinheiten (9) jeweils mindestens einen Schwingkreis aufweisen,

die Schwingkreise parallel an gemeinsame Leiterbahnsysteme (10, 11) angeschlossen sind, und

die Signale der Sensoreinheiten (9) Stromsignale der Schwingkreise sind,

wobei die Stromsignale der Schwingkreise zumindest einiger Sensoreinheiten (9) des Flächenelementes (1) unterschiedlich sind.

In a keyboard arrangement and method for identifying a pressed key according to the present invention, conductor lines (4', 6') at each key (B), which may be connected together, are connected to a ground plane (24, 23, 27) as a response to a pressing (P) of a key. The pressed key (B) is identified by detecting the conductor lines that are connected to the ground plane. All the conductor lines may be connected as pulled-up inputs of a detector circuit, and any conductor line or combination of conductor lines may be used to identify a key. A noticeably greater number of keys may be simply identified with the same number of conductor lines than is possible in a solution according to the prior art. In an advantageous embodiment of the present invention, the means for connecting the conductor lines (4', 5', 6', 7') to the ground plane (27) is a conductive plate (23), which essentially covers the whole keyboard. This also provides a good shield against electrostatic discharges and other interference.

Preisrechnende Waagen zu Selbstbedienungszwecken weisen herkömmlich eine Eingabetastatur mit Tastenfeldern 20,20′ auf, wobei die Tastenfelder 20,20′ mit Piktogrammen von Waren ver­sehen sind, deren Kilogrammpreis durch das betreffende Tasten­feld 20,20′ in die Waage eingegeben wird. Zur Anpassung an den jeweiligen Umfang des angebotenen Warensortiments ist erfin­dungsgemäß vorgesehen, die Waage mit austauschbaren Tasten­folien 19′ unterschiedlicher Tastenfeldeinteilung zu versehen und die Waage jeweils beim Wechsel der Tastenfolie 19′ auf die neu aufgelegte Tastenfolie einzustellen.

A moldable, impulse operation synthetic resin keyboard, and a method of fabricating the same, are provided wherein the keyboard achieves essentially standard, tactile feel and feedback, mechanical N-key rollover protection, and precise, reliable output. The preferred embodiment of the keyboard includes a synthetic resin base plate having a plurality of elongated, cantilever mounted flippers, along with a plurality of elongated, laterally spaced, inwardly and opposedly extending, pivotal, key-supporting arms. Upon depression of a key, the associated flipper is deformed until a release point is reached, whereupon the flipper is disengaged, allowing the flipper to quickly return to its rest position. A keyboard output is developed as the flipper, during overtravel thereof past its rest position, strikes a signal-generating assembly. An alternative embodiment of the keyboard includes a plurality of depressible keys mounted on respective upright synthetic resin flaps designed to collapse upon key depression and engage and move an underlying, resilient, U-shaped shifting member; the member in turn engages and shifts another U-shaped resilient element which supports one or more upstanding encoding posts. When the U-shaped element reaches a cocked position it is disengaged from the shifting member and allowed to snap back toward the original rest position thereof independently of subsequent return movement of the key and shifting member. The snap back motion is sensed and a corresponding key output signal developed.
