<P>PROBLEM TO BE SOLVED: To provide a signal detection and switch method in a dual mode tablet that has two operation modes, by a touch pen or by a finger. <P>SOLUTION: A microprocessor connects an electromagnetic induction module to an antenna module when executing an electromagnetic induction mode, continues the electromagnetic induction module when the microprocessor receives an electromagnetic induction signal in the electromagnetic induction module, searches for whether or not there is an electromagnetic induction signal, when the electromagnetic induction signal is not inputted, stops execution of the electromagnetic induction module, and switches the mode to a touch sense mode. The microprocessor connects the antenna module to an arbitrary one of the touch sense module or electromagnetic induction module in order and receives either a touch input signal or the electromagnetic induction signal when executing the touch sense mode. When the microprocessor receives an electromagnetic induction signal in a second loop, it switches to the touch sense mode, and receives the electromagnetic induction signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
