Abstract
PURPOSE:To simplify the structure and to improve the operativity by permitting a band selection switch to serve as a channel selecting switch without providing the channel selecting switch specially. CONSTITUTION:For example, when AM band selection switch (used for AM channel selection in combination) S1 is pushed, FF1 is set and FF2 is reset. Therefore, monostable multivibrator 7 is triggered by its set output to clear shift register 10. If switch S1 is pushed in this state, its output is supplied to the clock terminal of shift register 10 by way of chattering preventing circuit 3 and gate 5 every time switch S1 is pushed because FF1 stays set. Then, an AM channel selection signal is sent from channel selection control circuit 9 to reception part 14. Similarly, pushing switch S2 selects the FM channel.
