PURPOSE:To improve the operability of remote control by judging the direction of a commander. CONSTITUTION:Code signals S1-Sc outputted from IC 13a-13c by the operation of a painter key 1 1 are respectively supplied to light-emitting diodes 15a-15c through OR circuits 14a-14c. The code signal outputted from IC 16 by the operation of the pointer key 12 are also supplied to the lightemitting diodes 15a-15c through the OR circuits 14a-14c. The light-emitting diodes are arranged in an up-direction(15a), horizontally(15b) and in a down-direction(15c). Thus, light- emitting is executed form the light-emitting diodes 15a-15c by directivities La-Lc. The light-emitting diodes 15a and 15c and the light-emitting diodes 15b are light-emitted by the code signal so that outputs are weakened at the bondary of the is modulated so that outputs are weakened at the boundary of the respective light-emitting diode directivities. |
