The present invention relates to a device of the VHF tuner that can easily build a device in the VHF tuner.

In the conventional VHF tuner, the related configuration of the apparatus is similar to that of the first diagram.

In other words, here, the main shaft (10), the mizo lever (2), the e-ring (3) for fixing the mizo lever (2) to the lever shaft (9), the ball spring (4), the gear shaft (5), the micro gear (6). ), The oscillating core 7 and the main shaft gear 8 are configured.

In addition, when the micro-mechanism pushes the main shaft 10, the micro-gear 2 moves horizontally while being coaxed with the spring 4, and the micro-gear 6 and the oscillation core 7 mesh with each other. Rotating 10 transmits the rotational force to the main shaft gear 8, which rotates the oscillation core 7 so as to linearly move the oscillation core 7 so that the rotation is possible.

However, in this conventional technique, since the number of parts for achieving the crude means is made up of nine related parts as described above, the structure is complicated and causes the price rise of such an article.

In addition, the service life when the mechanical wear increases with the increase in the number of parts thereof is relatively decreased, and its reliability and disadvantages in after-care are heightened.

And, as a result, these problems lowered its practical value.

The present invention has been made to solve such a problem in the related art, which is a main shaft gear formed integrally with the main shaft shaft, and a driven gear driven with the main shaft gear is addressed as an integral mizoleva, and the longitudinal gear is an integral mizoleva. It is to provide an aesthetic device that has the mechanical simplicity and economical at the same time as it is related to the ungeared gear that is horizontally moved through the long hole of the shield plate shaft by the pushing force of the main shaft. .

This will be described in more detail below.

That is, in Figure 2 the device of the present invention is shown as a partial side cross-sectional structure.

Here, the main shaft gear 11 is integrally addressed to the main shaft 10, and the integral mizo lever 1 having the main shaft gear contact surface 1a that contacts the main shaft 10 is inclined with the shield plate 20 side.

The integral mizo lever 1 is a spring 4 mounted on the main shaft 10a so that the main shaft gear 11 side is held in a lifted state, and the main shaft gear contact surface 1a of the integrated mizo lever 1 is formed. And the inclined angle with the driven gear contact surface (1b) is formed.

The driven gear 12 is inserted into and inserted into the driven gear contact surface 1b in an inclined engagement with the main shaft gear 11, and the axis of the driven gear 12 is inserted into the shield plate 20 through the long hole 21. The micro-gear 6 which is positioned in the direction of the oscillation core 7 and slightly inclined through the long hole 21 is formed.

When the screen is finely adjusted, the present invention of such a configuration pushes the main side 10 to the right in the drawing so that the main shaft gear contact surface 1a of the integral mizo lever 1 abuts with the spring 4 is pushed together with the spring 4. The driven gear 12 stands up and is normally engaged with the main shaft gear 11 when approaching the shield plate 20 shaft.

In addition, the microgear gear 6 of the driven gear 12 shaft is positioned while making a slight inclination in the oscillation core 7 direction, and the driven gear 12 is driven by the rising action of the integral mizo lever 1. It remains in parallel with 10a), which causes the microgear 6 to engage the gear of the oscillation core 7.

In this state, when the main shaft 10 is rotated, rotational force is sequentially transmitted to the main shaft gear 11, the driven gear 12, and the microgear gear 6 so that the micro-shape function can be performed.

After the main shaft 10 is released, since the force given by the force does not exist, the integrated microscopic lever 1 and the like are returned to the position by the return energy of the spring 4.

The present invention can contribute greatly to the ease of assembly work and cost reduction by simply performing the aforesaid function by the related configuration with the parts to match the one-piece miso lever, and the reliability of the aforesaid device due to the organic structure is simply given. It is maintained well.
