Abstract

Die Erfindung betrifft eine Tastaturanordnung für eine elektronische Vorrichtung, insbesondere für eine mobile elektronische Vorrichtung, wie beispielsweise ein Mobilfunk-Endgerät, umfassend wenigstens eine Tastaturmatte (12) mit wenigstens einem Bedienungselement (16, 28), wobei das wenigstens eine Bedienungselement (16, 28) auf einer Betätigungsseite (14) von der wenigstens einen Tastaturmatte (12) vorspringt und wobei das wenigstens eine Bedienungselement (16, 28) auf einer der Betätigungsseite (14) abgewandten Kontaktseite (44) mit elektrisch leitenden Kontaktmitteln (46) versehen ist, wobei weiter das Bedienungselement (16, 28) bei Druckbeaufschlagung (P) aus einer Ruhestellung in eine Kontaktstellung verlagerbar ist, in welcher wenigstens zwei diesem zugeordnete elektrische Kontakte (50, 52) einer elektronischen Schaltung (48) über die Kontaktmittel (46) elektrisch leitend verbindbar oder verbunden sind. Bei der Erfindung ist vorgesehen, daß die Kontaktmittel (46) einen dem jeweiligen Bedienungselement (16, 28) separat zugeordneten Kontaktkörper (46) aus elektrisch leitendem, elastisch deformierbarem Material umfassen. Die Erfindung betrifft ferner eine elektronische Vorrichtung, insbesondere eine mobilelektronische Vorrichtung, wie beispielsweise ein Mobilfunk-Endgerät mit einer derartigen Tastaturanordnung.

Figure 00000001
The invention relates to a keyboard arrangement for an electronic device, in particular for a mobile electronic device, such as a mobile radio terminal, comprising at least one keyboard mat (12) with at least one operating element (16, 28), the at least one operating element (16, 28 ) protrudes from the at least one keyboard mat (12) on an actuating side (14) and the at least one operating element (16, 28) is provided with electrically conductive contact means (46) on a contact side (44) facing away from the actuating side (14), wherein furthermore, the operating element (16, 28) can be shifted from a rest position into a contact position when pressure is applied (P), in which at least two electrical contacts (50, 52) of an electronic circuit (48) associated therewith can be electrically conductively connected via the contact means (46) or are connected. The invention provides for the contact means (46) to comprise a contact body (46) made of electrically conductive, elastically deformable material which is separately assigned to the respective operating element (16, 28). The invention further relates to an electronic device, in particular a mobile electronic device, such as a mobile radio terminal with such a keyboard arrangement.
