Abstract

PURPOSE:To improve the accuracy of channel selection by dividing an operating into plural parts and fitting each divided operating plate to a support frame freely toward forward and reverse directions respectively. CONSTITUTION:The divided operating plates 45a, 45b are supported to be moved freely forward/backward to a ceiling plate 8d of a support frame 8 via the coupling between a long hole 46a and a pin 47a and between a long hole 46b and a pin 47b respectively. Furthermore, variable tuning parts 48a, 48b are provided corresponding to the operating plates 45a, 45b respectively. Through the constitution as stated above, since the lengthwise size of the operating plate is decreased, even if the channel selection collor of a channel selection member is butted to a position of both side ends of the operating plate, the possibility of the operating plate tilted on a horizontal plane is precluded by the butted forced, the smooth slidable movement of the operating plate is attained and also generation of a channel selection is prevented.

器を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present application has an operating part having a main drive gear on the shaft rod, and a driven gear that meshes with the main drive rV4 wheel. A pair of channel selection members made of 41 are mounted on a support frame so as to be able to move back and forth in a rotary pot and automatically return, and an operating member is provided between the operating portion and the pair of channel selection members. A magnifying machine + voice that enlarges the suppression stroke and transmits it to the channel selection system, and a pair of channel selection sections located on the left and right that switch each time the operating member moves back and forth to transmit the full force of the forward movement,
and a switching mechanism for preventing the forward movement of other forces, and further includes a switching mechanism for preventing the forward movement of the other force, and further includes a switching mechanism that maintains the forward movement state of one channel selection member that moves forward together with the operating portion, and the forward movement of the other channel selection members. The lock plate that releases the holding ring is press-fitted with the f-point member in the forward movement holding state, and the variable tuning tooth J! - Equipped with a fully variable actuating plate,
Regarding the push-button tuner configured to perform tuning by varying the variable amount and tuning element, and to perform presetting by meshing the main gear and the driven gear, it is particularly equipped with a large number of operating members and tuning members. The present invention provides a push-button tuner that is effective in such cases.

れがある。As mentioned above, the applicant proposed a push-button tuner configured to expand the suppression stroke of the operating member and transmit it to the tuning member. When attempting to provide a push-button tuner with many tuning functions by equipping a single support frame with a large number of tuning mechanisms each consisting of one operating member and two tuning members, the operating plate The horizontal dimension also becomes longer, so that when the tuning piece collides with the actuating plate due to the forward movement of the tuning members near both end positions of the actuating plate, the actuating plate is tilted more or less on the horizontal plane due to the force of the collision. This not only impairs the smooth sliding of the actuating plate, but also tends to cause tuning errors.

)' side guide piece 07)' is prevented from moving forward by the rear edge (push button side) of the rocking plate C3n, so the pinion (3) is prevented from moving forward. It moves forward while rotating horizontally while being guided by the guide piece (rack 06 of t7+') that is blocked, and the rack hole of external force that is hammered and engaged with this by 1ψ) moves it to the left side position. The guide piece a'n moves forward with a stroke twice that of the operating member (11), and the front part of this guide piece fin is in contact with the locking piece (a), so that the shaft rod (13 moves forward together with the guide piece α7).In this case, the locking piece (A) acts with the inclined edge C0 of the lock plate (261), and the spring (2!J) is applied to the lock plate (C). Since the lateral force in the direction opposing the current state is temporarily applied, the one head of the locking portion of the channel selection member a2. , the shaft rod (13' of the channel selection member (12.') is restored to its restoring spring +221'. - The storage section 081 of the left side position of the left side moved forward together with the force operating member (1) In this case, the rear edge of the actuating plate (c), which is retracted as the tuning member 112 in the right position is restored, is in contact with the locking part ■ and the locking step part 01 of the locking plate bending in the ν position. ) by locking it with the channel selection member (

When the abutment piece 051 provided on the front moves forward and collides with the opposing rotating plate (4G), the rotating plate 051 moves clockwise as shown in FIG. The tip of the leg collides with the one-force rising piece (351'), and the swing & C371 receives a clockwise rotating force.At this point, the protruding piece of the guide piece 07)' (2) Due to the H-contact between ' and the rear edge of the rocking plate GD, the rocking plate (three are still warped and -
It is held tilted in the opposite direction. In this state, when the push button (7) is released and the left guide piece (17I) moves back together with the operating part (1), the protrusion 9 moves towards the rocking plate Gη as shown in FIG. 1 (C). Retreat while sliding on the side edges,
And the guide piece on the left side (201' is fully restored)
In this state, the rocking plate (3'l) is tilted clockwise so that its rear edge crosses the left guide hole 125+i, as shown in Fig. In this way, the switching mechanism C (31) is alternately inverted and switched in the left and right direction for each reciprocating movement of the operation unit side (1), and the tuning part gain f12, (12) is shifted left and right.
- The zero forward movement of the guide piece (171, θ7)' is relatively prevented.

When trying to provide a push-button tuner with many tuning functions by equipping a large number of channels, the horizontal dimension of the operating plate (center) becomes correspondingly long, so the lengthwise direction of the operating plate (c) In 1!P, which performs channel selection by forward movement of the channel selection member near the end of
There is a risk that the actuating plate u51 will tilt to some extent on a flat surface due to the force of collision with the actuating plate (451').
This has the disadvantage that the smooth sliding of the channel is impaired and that it also causes tuning errors.

It is characterized by:

Each variable tuning section (481a, (48b) is also composed of a coil body for AM band and a variable element, and the tuning mechanism installed on the flexible support frame can be used for different bands, for example, AM band and FM.
When distinguishing between band use and force variable tuning part a*
It is composed of a coil body and a variable element for the AM band, and the external power variable tuning section (4 islands are composed of a coil body and a variable element for the F'M band).

品を配設することができて便利である。In this way, when distinguishing the variable tuning section for each band, the length of the variable tuning section that can be configured with a short variable stroke is changed to a variable tuning section that requires a long variable stroke at the expense of electrical characteristics. It is no longer necessary to design according to the length dimension of the tuning section, which makes it easy to design and manufacture the length, and because the overall depth can be shortened in a part, the shortened part can be used to create an electrical circuit. It is convenient to arrange parts.
