Claims (7)

1. Dual-Betriebsmodus-Tastatur, von welcher Signale zu einem Empfänger in einem Computer über eine Leitung oder auf drahtlose Art und Weise sendbar sind, und welche aufweist:
eine Tastatur mit einer internen Schaltkreiseinheit, welche einen Mikroprozessor, einen Matrixschaltkreis und einen Oszillator aufweist, wobei der Mikroprozessor die Signalleitungen CLK, DATA, Vcc, GND aufweist, welche elektrisch über einen Schaltdetektor, welcher an einen Batterieladeschaltkreis angeschlossen ist, an einen Steckverbinder angeschlossen sind, und der Steckverbinder mit dem Computer über eine Signalleitung verbunden sein kann, und der Mikroprozessor eine Auswahl/Steuer-Leitung aufweist, welche mit dem Schaltdetektor elektrisch verbunden ist, und
ein Signalübertragungsmodul, welches außerhalb der Tastatur angeordnet ist und mit dem Schaltdetektor und dem Batterieladeschaltkreis elektrisch verbunden ist, wobei das Signalübertragungsmodul das Signal der Tastatur in Abhängigkeit davon, ob die Signalleitung nicht mit dem Steckverbinder verbunden ist, zu dem Empfänger sendet,
wobei die Auswahl/Steuer-Leitung des Mikroprozessors einen geringen Spannungspegel aufweist und der Schaltdetektor derart geschaltet ist, daß die Batterie den Mikroprozessor mit Energie versorgt, solange die Signalleitung nicht mit dem Steckverbinder verbunden ist,
und wobei die Auswahl/Steuer-Leitung des Mikroprozessors einen hohen Spannungspegel aufweist und der Schaltdetektor derart geschaltet wird, daß der Computer den Mikroprozessor mit Energie versorgt und die Batterie von dem Batterielade­ schaltkreis aufgeladen wird, solange die Signalleitung mit dem Steckverbinder verbunden ist, und wobei das Signal der Tastatur über die Signalleitung zu dem Empfänger des Computers gesendet wird.1. A dual operating mode keyboard, from which signals can be sent to a receiver in a computer via a line or in a wireless manner, and which comprises:
a keyboard with an internal circuit unit, which has a microprocessor, a matrix circuit and an oscillator, the microprocessor having the signal lines CLK, DATA, Vcc, GND, which are electrically connected to a connector via a switch detector which is connected to a battery charging circuit , and the connector can be connected to the computer via a signal line, and the microprocessor has a selection / control line which is electrically connected to the switching detector, and
a signal transmission module which is arranged outside the keyboard and is electrically connected to the switching detector and the battery charging circuit, the signal transmission module sending the signal of the keyboard to the receiver depending on whether the signal line is not connected to the connector,
wherein the selection / control line of the microprocessor has a low voltage level and the switching detector is switched such that the battery supplies the microprocessor with energy as long as the signal line is not connected to the connector,
and wherein the selection / control line of the microprocessor has a high voltage level and the switching detector is switched such that the computer supplies the microprocessor with power and the battery is charged by the battery charging circuit as long as the signal line is connected to the connector, and wherein the signal from the keyboard is sent via the signal line to the receiver of the computer. 2. Dual-Betriebsmodus-Tastatur nach Anspruch 1, wobei das Signalübertragungsmodul ein Hochfrequenz (RF)-Modul ist. 2. Dual operating mode keyboard according to claim 1, wherein the Signal transmission module is a radio frequency (RF) module.   3. Dual-Betriebsmodus-Tastatur nach Anspruch 1, wobei das Signalübertragungsmodul ein Infrarot (IR)-Modul ist.3. Dual operating mode keyboard according to claim 1, wherein the Signal transmission module is an infrared (IR) module. 4. Dual-Betriebsmodus-Tastatur nach Anspruch 1, welche außerdem ein Lichtemissionsmodul aufweist, welches aufleuchtet, wenn die der Tastatur zugeführte Leistung nicht ausreichend ist.4. A dual mode keyboard according to claim 1, which also has a light emission module that illuminates when the keyboard power is insufficient. 5. Dual-Betriebsmodus-Tastatur nach Anspruch 1, wobei das Signalübertragungsmodul in der Tastatur eingebaut ist.5. Dual operating mode keyboard according to claim 1, wherein the Signal transmission module is built into the keyboard. 6. Dual-Betriebsmodus-Tastatur nach Anspruch 1, wobei der Steckverbinder ein PS/2-Steckverbinder ist.6. Dual operating mode keyboard according to claim 1, wherein the Connector is a PS / 2 connector. 7. Dual-Betriebsmodus-Tastatur nach Anspruch 1, wobei der Steckverbinder ein USB-Steckverbinder ist.7. The dual mode keyboard according to claim 1, wherein the Connector is a USB connector.
