PURPOSE:To eliminate inconvenience in use by giving reversing operation to the switching mechanism so as to select the preceding station when a channel selection member in holding state is restored attended with the channel selection by other channel selection mechanism. CONSTITUTION:Suppose that an operating member 2 for the channel selection mechanism is depressed to select tentatively a station included in the other channel selection mechanism other than the said channel selection mechanism when a channel selection member 23 at the left position is held in the forward state. Then other station is selected by the operation. In the process of the selection, a lock plate is moved laterally tentatively and the member 23 held in the forward state is retrogressed. Then in the process, a claw piece 30 of the member 23 acts on an engagement step 22a of an operation member 19 to receive a counter clockwise torque and a switching lever 7 is reversed counter clockwise. In depressing the pushbutton from the state, the member 23 is forwarded together with the member 2 and restores to the original state and the member 23 of a couple of channel selection members 23, 23' is selected with priority.
