Abstract

PURPOSE:To simplify the entire operation, by giving the restart function to the automatic tuning operation so that the operation in receiving the desired station can be limited to only two operations of start and stop. CONSTITUTION:The 1st switch device 11 for start is operated, the automatic tuning circuit 12 is driven and the reception frequency of the tuner 13 is changed with the driving of the circuit 12. When the reception frequency is received with this frequency change, the stop signal is fed to the circuit 12 from the reception detection circuit 14 to stop the channel selecting operation. In this operation, the stop signal and the smooth start signal are fed to the restart circuit 15 from the detection circuit 14. Further, the restart signal is fed to the circuit 12 from the circuit 15 in a prescribed time interval, the circuit 12 is driven again and channel selection is made at the tuning circuit 13 until the desired station can be received, the operation of the circuit 12 is released by the operation of the 2nd switch device 16 for restart release, allowing to receive the signal from the desired station.
