Description

[Detailed description of the invention] The present invention relates to the invention of a kick arm for a push-button tuner, which makes it possible to form the push-button tuner with a relatively narrow width.
Furthermore, each of the push buttons provided can have the same configuration.

In the case of a push-button tuner, normally the tuning operation is enabled by a manual rotary shaft, but when a reader with a push button is pressed, the clutch mechanism is switched to enable one-touch tuning by the push-button reader. In order to do this, a kick arm is used, that is, when the push button is pressed, the kick arm is first actuated to switch the clutch mechanism.

By the way, the kick arm used for this purpose is a comb-shaped one in which finger-like passive parts are arranged in a series at regular intervals on the upper or lower side. In this case, the push button readings are positioned on each side of the passive parts at a predetermined interval, and the operating parts protruding from the sides of the readings form a relationship that acts on the passive parts when pressed. Therefore, at one end of the kick arm, a distance necessary for pivoting must be taken from the protruding position of the driven part on one side of the kick arm to form a pivoting part to the machine frame. There is a major restriction when the length of the kick arm is increased and the push button tuner is therefore formed narrow.

Therefore, in order to avoid such disadvantages and to reduce the width of the push button tuner, the passive part at one end of the kick arm is provided close to the adjacent passive part, and this one end Regarding the passive part in the section, the push button reading is attached to the other side of the passive part (all other push button readings are attached to one side of the passive part), and by doing this, the push button reading is attached to the other side of the passive part. - The push button reading assembly assembled on the other side of the passive part as described above is located in the distance area where the pivot part is formed from the driven part of the side end to the machine frame, that is, the pivot distance of the kick arm is Since it is shared by the reading arrangement area, the width of the push button tuner as a whole can be reduced.

However, in the case where the width of the push button tuner is narrowed in this way, as mentioned above, regarding the push button reading incorporated in the other side of the passive part, the protrusion direction of the operating part with respect to the kick arm passive part may be other than that. In order to obtain such a push button synchronizer, it is necessary to prepare two types of push button readings with different protruding directions of the operating parts, and this type of push button pitch is opposite to the direction of each push button reading. This has the disadvantage of complicating the management of parts and manufacturing and assembly of the device.

The present invention has been devised after repeated studies in view of the above-mentioned circumstances, and the specific embodiment thereof will be explained with reference to the attached drawings. A kick arm 5 is proposed whose arrangement relationship with each push-button reader 1 is shown in FIG.

That is, the kick arm 5, which has the pivot parts 15 for the machine frame 10 at both ends, has the passive parts 3 on its upper side, which is similar to the conventional one described above, but A bent part 13 is formed at the tip toward the reading setting area, and the passive part 3a at one end of the kick arm 5 is close to or integral with the adjacent passive part 3. Therefore, the bending direction of the bent portion 13 is opposite to that of the other passive portions 3, and the bent portions 13 in these passive portions 3, 3a are symmetrical, and the push button reading 1 or attached thereto is The operating portion 1b of the provided member 1a is arranged so that when the push button reading 1 is pushed into the push button 8, the operating portion 1b acts on the bent portion 13 to actuate the kick arm 5.

The entire structure of the push button tuner assembled with the push button readout 1 and kick arm 5 as described above is as shown in FIGS. A slide plate 2 on which the core 6 for the coil 7 is arranged is slidably provided by guide rods 12, 12 provided on the machine frame 10, and such a slide plate 2 is engaged with the crank 23. , and this crank 2
As is well known, the horizontal rods 23a, 23a are connected to the frequency regulating member 14 provided in the push button reading 1 as described above, and are rotated to obtain the desired tuning tuning. A manual rotation shaft 9 is separately provided on one side of the machine frame 10.
is provided, and by rotating it, fine synchronization can be achieved.

However, the kick arm 5 has an operating trochanter 25 in a part thereof.
is attached, and this operating trochanter 25 faces the kick lever 16, and when the kick lever 16 is actuated by pressing the push button reading 1 as described above, the kick lever 16 is operated and the clutch mechanism 4 is switched. This is intended to create a one-touch state of synchronization.

In the embodiment described above, the passive part 3 disposed on the kick arm 5 is provided to protrude upward and is therefore pivoted to the lower side of the driven part 3 or to the machine frame 10, but this relationship may be reversed depending on the case. Even if the upper side of the arm 5 is pivoted to the machine frame 10 and the passive part 3 is disposed downward, it can be completely fixed by protruding the operating part 1b of the above-mentioned push button reading 1 or the member attached thereto. It is clear that a similar result can be obtained, and furthermore, the passive part 3a and the adjacent passive part 3 may be integrated, and the bent parts 13 may be provided oppositely on both sides of the integrated passive part.

It is clear that other structural relationships can also be implemented with appropriate changes.

According to the present invention as described above, the bent portions 13 are formed in each passive portion 3 disposed on the kick arm 5, and the push button reading 1
Or, since it is operated by the operation part 1b of the member 1a attached thereto, the operation is particularly provided on the side of each push button reading 1, which is generally located in the middle of each passive part 3. It is no longer necessary to form a section, and there is no need to form a section.
A smooth switching operation can be achieved by the operation part 1b formed in the width direction of the kick arm 5, and the driven part 3a at one end of the kick arm 5 is connected to the adjacent driven part 3.
Since the bent part 13 is formed in the opposite direction to that of the other passive part 3, the pivoting distance of the kick arm 5 to the machine frame 10 is determined by the distance of the push button reading 1 at this one end. To provide a narrow and compact push button adjustment device of this type that can be shared in the setting area, and in addition, it also includes the operation part 1b of the push button reading 1 or the member 1a attached thereto. It is sufficient that the configuration is uniform throughout, and 2
There is no need to prepare one or more push button readings, and the production management and production assembly can be simplified. be.
