摘要:
Die Tastatur hat eine äußeren Folie (14), die sich gegen einen Betätigungswiderstand niederdrücken läßt, um einen lokalen elektrischen Kontakt zu schließen, und eine Auswerteelektronik zur Erfassung des Orts der Niederdrückstelle und der wirkenden Niederdrückkraft. Die Auswerteelektronik läßt sich hinsichtlich der Zuordnung bestimmter Niederdrückstellen zu jeweiligen Tastenbetätigungsfunktionen und hinsichtlich der Schaltschwelle frei programmieren. Sie ist an den vorgenannten Niederdrückstellen für den Anwender unveränderlich fest programmiert. Die Tastatur weist eine die Niederdrückstellen identifizierende fühlbare Kennung auf.
摘要:
A membrane switch is provided which comprises a base layer (10) of non-conductive material, a static circuit in the form of a first electrical conductor or conductors (11) mounted on said base layer, a spacer layer (14) having at least one aperture (15) therein which is coincident with said first conductor or conductors (11), a dynamic circuit in the form of a second electrical conductor or conductors (13) coincident with said aperture facing said first electrical conductor or conductors (11), and a resilient membrane (12) covering said second conductor or conductors (13). Within the area bounded by the aperture a discontinuous layer of non-conductive material (16) is provided between said first conductor or conductors and said second conductor or conductors, whereby the first conductor or conductors is/are spaced from the second conductor or conductors until the resilient membrane is depressed by the user's finger and contact is made between the opposed first and second conductors in zones free of the non-conductive material. In this manner advantage can be made of the deformable texture of the fleshy pad of the finger in that the latter will press one conductor (13) on both sides of a line of non-conductive material (16) into contact with its opposite conductor the pad temporarily deforming to accommodate the non-conductive line.

There are provided a design sheet (5) attached to the surface of an upper electrode film (1) of a touch panel (4) such that the design sheet is protruded at its periphery from the touch panel (4) and a touch-panel-unit casing (6) which is integrally molded with the design sheet (5) such that the casing is covered at its surface with the design sheet (5) and surrounds the side surfaces of the touch panel (4).
摘要:
A touch panel and an electronic device using the touch panel have satisfactory, reliable operability. The touch panel is used for an operating section of the electronic device. In this touch panel, upper and lower substrates 21 and 22 have upper and lower electrode layers, respectively, and face with an established spacing. Respective center portions of the substrates 21 and 22 protrude upward like a dome.
