<p>PURPOSE:To prevent erroneous operations to improve operatability, by controlling the start of picture recording by operations of picture recording and reproducing buttons of the remote control transmitter for the VTR. CONSTITUTION:In case that the picture recording switch of operation switch part 1 of the key matrix is operated to set to the picture recording stand-by state and the reproducing switch is operated to set the picture recording start state, the control code signal corresponding to the switch operation is generated by encoder part 2 and has the carrier wave modulated by modulator 3 and is supplied to LED4. The operation signal emitted from LED4 is demodulated through photodetector 5 by demodulator 7 and is supplied to decoder part 8, and the control code sigal is decoded, and VTR9 is operated by the signal output corresponding to the opration switch.</p> |
