Description

[Detailed description of the invention] The present invention relates to the invention of a core movement operation mechanism for a push-button tuner, and provides a core movement operation mechanism for a push-button tuner that is simple in structure, thin, and compact, and is lightweight and low cost. This is what I am trying to do.

In a push-button tuner, if the push-button reading area is made thinner, it can be suitably combined with a receiver or other equipment and installed compactly for use in a vehicle or other applications, which has a great practical effect. .

For this purpose, various proposals have been made in the past regarding thinned push-button tuners in which the push-button reading plate surface is parallel to the tuner base surface.

However, even in such a conventional thinned tuner, the core slide is moved in conjunction with the movement of the memory slide, which is actuated via the frequency regulating member provided in the reading section parallel to the surface of the instrument base, as described above. The configuration for operation does not necessarily satisfy the objectives of thinning and miniaturization.

In other words, since the push button reading is operated by sliding in the depth direction of the table, the memory slide mentioned above is slid in the width direction of the table. If the core were to be moved in and out of the coil, the width would be extremely large. Therefore, a core slide was provided that changed the operating direction of the memory slide and acted in the depth direction, and this core slide The core provided in the holder is moved in and out of the coil arranged with the axis line taken in the depth direction of the holder.

However, with such a structure, as mentioned above, the mechanism for converting the sliding direction between the memory slide and the core slide to obtain an appropriate amount of motion has a large number of parts, including the guide part, and requires considerable effort. This has the disadvantage that it is unavoidably complicated, and is particularly unsuitable for thinning.

The present invention was devised after further study in view of the above-mentioned circumstances, and it improves the relationship between the memory slide and the core slide in the thinner product as described above, and improves the relationship between the memory slide and the core slide. It has also been possible to make the parts even thinner, and moreover, the preferred assembly has succeeded in achieving a working relationship.

That is, the specific embodiment of the present invention will be described with reference to the attached drawings.The overall configuration of the push button tuner is as shown in FIGS. Push button reading boards 1 each having a push button 6 (generally about 5 buttons) are arranged at regular intervals with their plate surfaces parallel to the surface of the table 10.
The configuration of each push-button reading mechanism arranged in this way is as follows: a fixing piece 2 for fixing the frequency regulating member 3 to the reading mechanism 1;
The fixing piece 2 is formed with a fitting hole 2a for receiving the shaft support 3f of the frequency regulating member 3 described above, and a cut portion 2b is formed from the fitting hole 2a, and an opening of the cut portion 2b is formed. Clamping parts 2c are provided oppositely on both sides of the ends, and the push button 6 attached to the base end of the above-mentioned reading group 1 has the clamping parts 2c,
A slide member 4 having engaging portions 4a, 4a acting on the slide member 2c is attached.

As shown in the figure, the distal end of the frequency regulating member 3 serves as the operating section 3a, but a pivot hole 3b is formed at the base end. The head 5b of the child 5 is received, and the tip 5a of the pivot 5 protrudes from the insertion hole 11 of the reading board 1 to the back surface of the reading board 1, and is inserted into the guide hole 15 formed in the table 10. As shown in FIG. 2, the engaging portion 5c is formed in the intermediate portion of the pivot 5 to guide the pushing operation of the reading group 1. It is fitted into the engaging portion 3c coaxial with the hole 3b in a relationship that prevents rotational operation.

Furthermore, in this illustrated example, a Sun Tzu 1 for operating a switch changeover plate 7 as shown in FIG.
2 is provided and engages with the operating hole 7a of the switching plate 7, and a spring mounting part 13 is formed on one side of the tip of the reading board, and a spring mounting part 13 is formed between the spring mounting part 13 and the device stand 10. A spring 14 for returning the reading 1 is interposed.

The operating section 3a of the frequency regulating member 3 as described above
The memory slide 8 is operated in the width direction of 0, and the operating portion 3a is a passive portion 8 consisting of opposing inclined sides.
c, 8c, and the memory slide 8c
This sliding action is guided by the guide holes 8d and 8d provided on both sides of the container and the pin 10d of the table 10.

For this memory slide 8, a core slide 16 is provided for moving a core (not shown) in and out of a coil 9, which is provided with an axis in the depth direction at the back of the device stand 10 (
However, in the present invention, in order to achieve a linked operation between the memory slide 8 and the core slide 16, and to change the direction of operation by the memory slide 8 and obtain a preferable operation of the core slide 16, the core Slide 1
A Sunzi 17 is provided on the bottom surface of the memory slide 8, and an inclined hole 8a is formed in the memory slide 8, and the Sunzi 17 is engaged with the core slide 16. It is hollowed so as to slide in the depth direction of the stand 10.

As shown in the figure, the rising portion of the core slide 16 is guided by the guide 19a of the support body 19 to which the coil is attached, and the core can be moved in and out in an accurate state.

In the embodiment described above, the Sun Tzu 17 is attached to the core slide 16, and the inclined hole 8a is attached to the memory slide 8.
However, in the case of the present invention, the structural relationship of this part is appropriately reversed, that is, the core slide 16 is formed with an inclined hole 16a as shown in FIG. Of course, it is also possible to provide

That is, if this is done, the area of the bottom surface of the core slide 16 will be slightly larger, but the Sun Tzu 17 of the memory slide 8 will be larger.
As shown in the figure, the mounting portion can be reduced to a certain extent since it is sufficient to simply mount the Sun Tzu 17.

It is clear that the Sun Tzu 17 can be operated very smoothly by providing a rotatable roller-like member.

Further, the present invention can be implemented as shown in FIG.

That is, the gear 17c is used as the Sun Tzu, and the inclined hole 8
A rack 8b is formed on the edge of the hole a to be engaged with the gear 17c, and by doing so, accurate interlocking between the memory slide 8 and the core slide 16 can always be obtained.

In addition, when using the gear 17c and the rack in this way, if there is a gap between them and the accuracy of the operating amount is impaired, the rack 8b should be made double and the rack may be connected to the gear using a spring or the like. It is possible to prevent backlash during engagement and improve its accuracy.

When using this invention as described above, the memory slide 8
It is clear that the operating direction can be changed appropriately between the core slide 16 and the core slide 16. Therefore, the core can be moved in and out of the coil 9 provided in the depth direction of the device base 10, and the core slide 16 can be operated in a relatively wide width. It is possible to form a narrow tuning mechanism, and moreover, the memory slide 8 as described above can be used.
The core slide 16 is a simple engagement between an inclined hole and a Sun Tzu, and does not require any special members, and there is almost no increase in thickness due to the change in the operating direction in the part. It is possible to provide a thinner mechanism,
Of course, it has the advantage of being lightweight and low cost, and is a highly effective device in practical terms.

Further, as an embodiment of the present invention as described above,
By forming a rack on the edge of the above-mentioned inclined hole and using a gear as a gear, a highly accurate actuation amount can be obtained.
