Abstract

PURPOSE:To enable effective level displaying to be performed by letting the emission color of light emitting elements differ depending upon above or below the reference level of the preset input signal. CONSTITUTION:Where a switch 6 is held changed over to the stationary terminal (a) side, turning displaying by the number of lighting of the light emitting diodes of a display device 8 is accomplished by the turning signal from a radio receiving part 1 and arrangement is so made that the number of lighting of the light emitting diodes becomes most at the best tuning point at this time. When in such a case the signal is tuned to the broadcasting signal of the highest field intensity, red emission also takes place in addition to green emission but when it is tuned to the broadcasting signal of a small field intensity, only the green emission takes place and the field intensities of the broadcasting signal may be judged simply by viewing the difference in these emission colors. When the switch 6 if changed over to the stationary terminal (b) side, the plural light emitting diodes subsequently light from the left side one in correspondence to the increase or decrease of the signal levels from a tape recorder part 2 and in addition, the number of their lighting also increases or decreases.
