PURPOSE:To attain the control of three kinds of devices by switching with one set of remote controller by providing the 1st and 2nd changeover switches and operating the changeover switches through combination. CONSTITUTION:In bringing the mode to the television mode (state shown in Fig.) by changing over the changeover switch 1, the part between the changeover switches 1 and 2 is opened, and the switching of a device discriminating code and inhibition or switching of various key functions are attained independently of the changeover switch 2. In bringing the mode to the VTR or the video disc player mode by switching the changeover switch 1, the part between the changeover switches 1 and 2 is conducted and the mute key and the stop key are changed over. Further, in selecting the VTR mode or the video disc player mode by the changeover switch 2, through plural contacts interlocked in the changeover switch 2, the switching of the device discriminating code, switching of tone color of a piezoelectric buzzer 7 and inhibition of various key functions in the other key matrix 3 are conducted so as to bring the mode to the VTR mode or the video disc player mode. |
