Abstract

PURPOSE:To simplify the structure and improve the precision of channel selection, by providing a lateral moving plate energized in one direction. CONSTITUTION:For example, when a channel selecting member A1 is depressed, a projecting part A' is brought into contact with an inclined edge 241, and a lateral moving plate 20 is moved laterally against a spring 22 in the right direction. When the channel selecting member A1 is depressed futhermore, the projecting part A' goes into a groove 231, and a projecting part 7 of a storage member 2 is brought into contact with the apex of a cam part 8 to stop the advance of the channel selecting member A1, thus achieving channel selection. When for example, channel selecting member A2 is depressed under this state, the projecting part A' of the channel selecting member A2 is brought into contact with the inclined edge 241 and tries to advance while moving the lateral moving plate 20 laterally in the right direction; but the lateral moving plate 20 cannot move because the projecting part of the channel selecting member A1 is in the groove 231 still, and the channel selecting member A2 cannot advance. Consequently, the projecting part 7 of the storage member 2 of the channel selecting member A2 is not brought into contact with the cam part 8.
