。Conventionally, a pair of selection members are arranged in parallel on the left and right sides of one push button member in a mold, and the push button member and one of the left and right channel selection members are connected through a connecting member that moves laterally in a direction perpendicular to these members. They are relatively connected, and by pressing the push button member, one channel selection member connected thereto is moved together to select, for example, an AM band station, and the other channel selection member selects, for example, an FM band station. A push-button type tuner configured to allow the above-mentioned connection member to be formed into a fan shape, the center point of which is pivotally connected to the push-button member, and a rotational force applied to the connection member, thereby providing a connection thereto. A push-button tuner configured to relatively connect either the left or right tuning member to the push-button member via a piece, or the connecting member is attached to the push-button member so as to be tiltable in a vertical state, and the connecting member A push button type tuner configured to relatively connect either the left or right channel selection member to the push button member via protrusions provided on the left and right edges by applying a tilting force to It is known from Japanese Patent Publication No. 46-17684, Japanese Patent Application Laid-Open No. 46-3301, and Japanese Patent Publication No. 45-21722.

換が円滑に行われない不都合がある。However, all of the above configurations not only have a complicated structure and are troublesome to manufacture, but also have to be connected after the connecting member is moved from one channel selection member that is connected to the push button member and the connected state is separated. Since the connection member is connected to the other channel selection member, if there is any deviation in the length direction between the push button member and the selection member, the connection member cannot be switched smoothly. There is.

スライド板１２ｂを横動する。Then, one protrusion 23a provided on the shift plate 19 is inserted into the cut groove 24 provided on one channel selection member 1a, and the suppression piece 4
1 and 3, in which the arm 2 is locked to the protrusion 23a, thereby restraining the sliding movement of the one channel selection member 1a.
When the push button 9 is pressed to move the push button member 1c forward from the state shown in the figure, the connecting piece 17 tilts clockwise about the shaft piece 7 as a fulcrum, as shown in FIG. 5, and the channel selection member 1b moves forward. ,
The protruding pin 3' deeply enters the cam hole 16 opposite to it and moves the slide plate 12b laterally.

えばＡＭバンドの成る局を選択する。The regulating plate 3 provided with the protruding pin 3' is restrained at a required rotation angle to select the station formed on the arm arm 2, and therefore the sliding plate 12b corresponds to the required rotation angle of the regulating plate 30. Then, a variable tuning element (not shown) interlocked with the slide plate 12b is changed so that the channel selection member 1b selects, for example, a station in the AM band.

ンドの成る局が選択される。The above-mentioned action can be achieved by moving the shift plate 19 laterally to the right in FIG.
for example, to the FM band, and insert the protrusion 23b into the cut groove 24 provided on the other tuning member 1b.
It is exactly the same when the push button 9 is pressed and one of the channel selection members 1a is moved forward together with the push button member 1c from the state where the sliding of the channel b is restrained.In this case, the channel selection member 1a selects the stations of the FM band. selected.

回転状態におかれる。Next, when the push button 9 is pulled forward from the state shown in FIGS. 1 and 3, in which one channel selection member 1a is restrained from sliding by the protrusion 23a of the shift plate 19, as shown by the imaginary line in FIG. As shown, the connecting piece 17 rotates counterclockwise about the shaft piece 7, and the actuating part 5 of the channel selection member 1b retreats from the wrist arm 2, and the restraining state of the regulation plate 3 is released. The plate 3 is left in free rotation.

２ａ、１２ｂの横動変位量を記憶させる。Then, as in the conventional case, the manual adjustment mechanism 14 is operated to laterally displace the slide plates 12a and 12b, and the variable tuning element is varied, thereby selecting a desired station, and then the push button 9 is pressed.
is pressed to move the push button member 1c forward, and align the projecting pin 3' provided on the regulation plate 3 of the other channel selection member 1b that moves together with the apex of the cam hole 16 facing it, and then move the regulation plate 1c forward. 3 is restrained by the restraining piece 4, and the sliding plate 1 is attached to the regulating plate 3.
The amount of lateral displacement of 2a and 12b is stored.

し、第４図の状態に復する。After the tuning point is memorized in the tuning member 1b in this way, when the push button 9 is released, the tuning member 1b is moved back together with the push button 1c by its restoring spring 27, and this retreat is caused by the stopper a. It stops at the position where it abuts the front plate of formwork A and returns to the state shown in FIG. 4.

なく、且つ連結手段の構成が極めて簡単である。As described above, according to the present application, a push button member and a pair of channel selection members disposed above and below the push button member are connected by a connecting piece, and the channel selection member connected to the push button member is connected to the push button member by the lateral movement of the shift plate. Since the structure is configured to selectively restrict the sliding movement of one of the two, unlike the conventional case in which the connection between the push button member and a pair of connection members is switched by moving the connection member using a shift plate, There is no risk of malfunction occurring during the switching operation, and the structure of the connecting means is extremely simple.

得て、同調器の小型化に有効であるなどの利点を有す。Further, according to the present application, the sliding stroke of the push button member is reduced to 1/2 of the sliding stroke of the channel selection member, and the shift plate is vertically overlapped with the front plate of the formwork, so that it is not possible to shift as in the conventional case. Since the plate does not extend greatly in front of the front plate of the formwork, the depth of the entire tuner can be increased (shortened), which has the advantage of being effective in downsizing the tuner.
