より選局を達成する。Conventionally, a first arm includes a rotatable regulation plate, a restraining piece for restraining the regulating plate by a tilting action, and a slidable operating member for imparting a tilting action to the restraining piece, and the first arm. A so-called second arm is connected to the metal operating part and has a push button at one end, and is configured such that a component force is generated in the connecting portion in a direction perpendicular to the sliding direction of the first arm. A tuning member related to the double arm type is well known, and this tuning member is slidably supported between the front plate and the rear plate of the device frame that constitutes the tuner, and can be selected by pressing a button. Tuning is accomplished by sliding the member forward to cause the regulating plate to act on a movable member that interlocks with the variable tuning element.

全史延長しておく必要がある。By the way, in the channel selection member configured in this way, in the lockout state in which the second arm is pulled forward with respect to the first arm to release the restraining state of the regulating plate, the tip of the second arm is not connected to the instrument. To prevent it from escaping from the rear plate of the frame, it is necessary to make the tip of the second arm longer than the tip of the first arm throughout the entire stroke required for lockout.

前進摺動を開始する。Next, when the push button 7 is pressed in the direction of the arrow from this state, the push button 7 and the first arm 1 move forward together, and the second arm 6, which is kept in an immovable state by the strong restoring spring 13', moves forward. One end 6' of the slot enters into the guide groove 7' and the one end 6' abuts the inner end of the guide groove 7', or the connecting shaft 8 abuts one end 9' of the elongated hole 9. , the second arm 6 also starts sliding forward.

とが出来る。In the above, when the regulating plate 3 is restrained due to the pressing operation of the push button 7, a component force V is generated between the diagonal hole 11 and the connecting shaft 8 as shown in FIG. A pressing force in the same direction is applied to the first arm 1 through the connecting shaft 8, and therefore the first arm 1 and the front and rear plates A that slidably support it
,, Vertical play that exists between the sliding holes a1 and a2 formed in A2 is prevented, and it is possible to improve the accuracy of channel selection.
