Abstract
PURPOSE: To simplify the channel selection greatly and at the same time to secure the announcement and automatic correction of the misoperation by selecting via the switch groups the tuner voltage corresponding to the contents which is connected to the control circuit and read out continuously.
CONSTITUTION: Memory element 2 stores the signals of key switch group 1 for channel selecting operation, and memory element 3 reads out the contents stored previously in sequence. And the contents are compared (4) between elements 2 and 3. Control circuit 5 continues the operation of sequential reading for element 3 with disagreement of contents by the signals of comparator 4 and stops the continuous reading when the agreement of the contents is obtained. Then tuner voltage VT corresponding to the contents which is connected to circuit 5 and read out continuously is selected via switch group 7. Thus, the key switch is operated based on the channel numbers. In such way, the channel selecting operation can be simplified greatly, at the same time ensuring the announcement and automatic correction for the misoperation.
