<p>PURPOSE:To eliminate the need for a display element exclusive for stereo reception mode by using the 1st or 2nd display element set at the side of a tape recorder also as a display element at the slide of a radio receiver. CONSTITUTION:When a tape is driven in the forward direction at the side of a tape recorder, a current flows via a power supply terminal 4, the 1st light emitting diode 7 and switch contacts 6a and 6c. Thus the 2nd light emitting diode 8 is turned on. Then it can be confirmed that a tape recorder mechanism 5 is working forward.While a switch 6 is changed over when the tape driving direction is reversed. Thus the diode 8 is turned on. Then a display signal terminal 2a of a stereo demodulator 2 is connected to the cathode side of the diode 8. Thus the diode 8 is turned on in a radio reception mode and also in a stereo demodulation mode. In such a way, the diode 8 serves as a display element for stereo reception mode and then functions as a display element for tape reverse mode when the tape is reproduced respectively.</p> |
