<p>PURPOSE:To improve operability of remote control by pressing a matrix-shaped switch, which corresponds to the cursor position of a cathode ray tube, by a finger, outputting a signal to show the turning-on and off condition of the respective switches, recognizing which switch is turned on and off and moving a cursor on the cathode ray tube. CONSTITUTION:When the primary switch, for example, the basic screen switch of a matrix-shaped touch switch part T1 is pushed by a finger F, the first switch layer and second switch layer of the part are operated and a switch signal is inputted to a transmission recognizing part T2. The transmission recognizing part T2 recognizes the inputted switch signal and outputs a recognizing signal S1. The recognizing signal S1 is inputted through a modulating part T3 to a demodulating part R3 of a receiver R and the demodulating part R3 takes out the recognizing signal S1 and outputs the signal to a reception recognizing part R2. The reception recognizing part R2 outputs a processing signal C1 to correspond to the signal S1. A control part R1 to input the processing signal C1 displays the switch information of a secondary switch on a screen 31 of a cathode ray tube 30.</p> |
