Abstract

PURPOSE:To decrease as less as possible the number of leading means, by discriminating whether an odd or even position is set and at the same time providing a circuit to apply the power supply voltage to either one of the power supply lines in accordance with the above-mentioned discrimination. CONSTITUTION:When the 2nd position is set by the position setting circuit 1, only the 2nd output transistor (TR) Q2 is turned on among the output TRs Q1-Q12 of IC4. As a result, the 2nd output line A2 is set at an earth level, and the tuning voltage of the volume VR2 is applied to the tuner through the diode D22 and the line 5. No diode is connected between the points (a) for the line A2. Thus the TR1 and TR2 are turned on with the TR5 turned off. The power supply voltage +16 is applied to the power supply line 8, and thus the light is emitted through a route of line 8 light emitting diode DL2 leading means L1 diode D12 2nd TRQ2 earth.
