Abstract
PURPOSE: To enable smooth tuning operation and to constitute the indicator excellent in visuality and less in malfunction, by the constitution that three light emitting elements are used and six states are clearly distincted.
CONSTITUTION: Three light emitting diodes 7, 16, 12 are placed. The unit consists of the FM receiver 1 consisting of the FM detection circuit 2 and muting signal generator 3, first and second level detection diodes 4 and 5. If no tuning is made to the receiver 1, diodes 7, 16, and 12 are not illuminated (A). Next, when the tuning element is turned clockwise and the tuning state is within the frequency range of f0- 200kHz∼f0-100kHz (where f0 is the center frequency of broadcast signal), only the diode 7 is in full illumination (B), and if the tuning condition is at f0- 100kHz∼ f0-20kHz, the diodes 7 and 16 are at half-illumination(C). Thus, since six states (A∼F) can be destincted, smooth and no malfunction tuning indication can be made.
