Description

DETAILED DESCRIPTION OF THE INVENTION The present application i4 is a multi-band push button which has a simple structure, obtains a female value Vc, is effective for miniaturization, and allows stations with many different frequency bandwidths to remain. The present invention provides an equation tuner.

Conventionally, an operating shaft with a push button and a pair of tuning shafts located on the left and right sides of the operating shaft, each having a tuning shaft that is screwed into a screw part and moves back and forth, are mounted on a support frame, and the operating shaft is pressed. At this time, either one of the % stations III is moved forward to maintain its forward movement state, and the tuning axis is set to η3t.

A push-button tuner configured to perform 14 stations by making the variable tuning element variable by providing a fully movable operating plate that can move forward and backward is known, for example, in Japanese Utility Model Application No. 53-43804. According to this configuration, the selective connection of the channel selection axis in the left and right positions +74- with respect to the operation axis is based on the separately provided selection switching mechanism &'C, so there is no extra space at the arrangement position of the length push buttons. Not only does it require the following, but it is also limited to switching between two bands, for example, the AM band and the FM band, and therefore has the drawback that a square tuner cannot have a tuning section for three or more bands.

Therefore, in the present application, in addition to improving these deficiencies, the tuning axis is moved to 8I by a slight pressing stroke of the operation axis, making the pressing operation of 'til + 1 at 8 easy, and synchronization. The device is designed to be miniaturized, and an example of its implementation will be described below in detail with respect to the surface.

Accordingly, the tuning piece (18 bit) moves forward and backward on the tuning axis.This movement in the forward and backward direction is the tuning piece 08.
The side surface of ' is guided by contact with the inner surface of guide piece 07)', and the tip of memory ttlL (181'2. (
4□a is in pressure contact with the spring, so the operating plate (・suddenly moves m+ backwards with the selection piece a8 etc.)
As a result, the variable tuning element 40 is changed to select a desired station.

In this way, write the desired station on the right side (one channel selection axis old) by moving stroke V of 1 piece of channel selection f181', and then press button (6). Then, as already mentioned, the switching mechanism (34) rotates as shown by the oscillating plate C in the position (a) of Fig. 41.

In this case, the locking piece (1!J is the inclined edge C3 of lock V2゜7j)
As a result, a lateral force is temporarily applied to the end of the lock plate in a direction that opposes the spring CJI). The locking between the piece O9' and the locking step c3z is released, and the channel selection shaft 01]' is moved to the guide piece o7 that is engaged with the moving piece (4).

When maintained in the J-motion state, the other driven gear (2) meshes with the main drive gear (5) as shown in FIG.

In this case, when both gears (5) and (2IJl) come into contact with each other.

The driving gear (5) moves forward against the spring (9), and the driven surface 4 moves backward against the spring f2a.

The meshing is not performed, but the meshing is automatically performed by rotating the driving tooth N (5171F-).

However, when the suppression of push button (6) is released from the state shown in Figure 9,
The operating shaft +I+ and the shaft bottle (lbJ,

Next, we will explain the switching operation of the geometry.

Figure 1 (A) to (A) shows the operating process of the switching mechanism that is switched by one reciprocating motion of the operating shaft (II). That is, the rotating plate (4υ) and the rocking plate (2) are both rotated counterclockwise. In the state shown in FIG. 1 (a) in which the snap spring (43) holds this state, the abutment piece 09 provided on the left guide piece 1 advances ifJ and the rotating plate ( When the contact pieces OjK and No. 14 are brought together, the rotating actuator 01) is reversed clockwise as shown in the figure (O), and the tip of the PAI piece collides with one of the rising pieces (36), and this Shake by!Fi2

y is the rocking plate (Fig. 21 shows the state in which y moves backward while sliding on the 1μj1 edge of the oscillation plate, and the guide piece 0n is oriented toward the light beam)
As shown in , the trailing edge of the rocking plate ■ is located at the left guide hole t',
! The switch mechanism Oa moves from left to right for each reciprocating movement of the operating shaft (1). It is switched in both directions and in reverse.

By the way, as shown above, the operating plate (piece) is connected to the operating shaft (11
In a configuration in which the object is moved in the same direction as , there are disadvantages as described below.

That is, from the state where one channel selection axis 1hll Gυ' is currently held in the MJ movement state and the actuating plate (decoy) collides with the front edge of its recording part (18+j), the other channel selection axis 0υ is operated.
When Al1 moves with l(11), in the forward movement process, the one tuning axis OI is restored by its culm springs Q and 9', and the actuating plate (IED is also moved backward from its culm spring f6VC). It moves to AiJ and collides with the memory part 0a of the other tuning axis 0υ which is in the middle of AiJ movement, and a so-called hammer action occurs. When is the most forward position on the tuning axis 0υ' (set to 1rC, and the other memory part (lji& is set at the rearmost position i on the tuning axis 0υ)), a strong attack occurs. Due to the mechanical vibration caused by this hammer action, some rotational force acts on the threaded joint between the tuning shaft ++ 11 and the tuning side (1&), causing tuning errors.

There is a fear that mechanical damage may occur at the abutting position.

Therefore, this book G1 is intended to address all such concerns.

When the tuning side of one tuning axis in the non-tuning state and the tuning side of the other tuning axis in the matching state are respectively at the rearmost position on the tuning axis, the tuning It is required that an abutting portion that abuts the actuating plate be provided on the operating shaft so as to be located between the A-base surfaces on the side.

That is, in FIGS. 1 and 3 and FIGS. 9 to 11.

G'LI is an abutting part provided on the piece f3)a of the support piece (3) with an upwardly extending length, and FIG. 15 shows an abutting part (70 and one pair of left and right selection piece Q8+,

This is exactly the same as the embodiment shown in FIG.

Book a is for KM commands to be applied diagonally upward. For example, a pair of channel selection machines PJ (in
can store stations in two different reception bands, and stations in two other different reception bands can be stored in a pair of tuning stations 1 and 11 in another set of tuning mechanisms. As a result, it is possible to provide a versatile defroster that can be selected by many receiving stations, preset operations can be performed easily and precisely, and the operation is reliable. There is no mechanical damage, the ability to obtain a high degree of channel selection accuracy, and the fact that the channel selection axis can be moved with a stroke twice as long as the movement stroke of operation 1, so the movement stroke of the 1 channel selection axis is the same as that of the conventional one. When making them equal, the distance between the rear surface of the support frame and the protruding end surface 1 of the push button becomes shorter, resulting in an overall depth of '8i.
- It has the advantage of being able to perform short pongeeing, and is an extremely useful invention as a multi-band tuning point.
