PURPOSE:To obtain a compact device which is reduced in width size and depth size by arraying a variable tuning part and a slide part piece for varying it on the array surface of a selecting member one over another. CONSTITUTION:An inverting mechanism E is provided with a coupling part 44 in one body and the variable tuning part 48 is provided with a rotary part piece 42 at other-end positions of lateral moving cam plates 14a and 14b opposite the mechanism E. This rotary part piece 42 is in an L shape and its center part is pivoted rotatably on a support; and one piece is connected to one of the cam plates 14a and 14b. The other piece of this rotary piece 42 and the coupling part 40 provided to the inverting lever 16 are set in the same direction. Further, the slide part piece 47 is fitted between them and the variable element of the variable tuning part 48 is supported and moved back and forth to select a channel. |
