Description

[Detailed Description of the Invention] The present invention relates to a tuning knob device for an electronic tuner.

As shown in FIGS. 1 and 2, the conventional channel selection knob device is designed such that the tips of the knobs 1, which are arranged in parallel, protrude from the hole 3 in the front door 2. In this case, due to variations, the knob 1 comes into contact with the hole 3 of the front door 2,
It may cause a defective return.

Therefore, it is necessary to provide a sufficient gap between the knob 1 and the hole 3, which is not desirable in terms of design.

The present invention has been devised to deal with such problems, and will be explained below based on drawings showing an example of implementation.

That is, in FIGS. 3 to 6, 11 is the main body of the tuning switch of the electronic tuner, 12... is a hole laterally partitioned by ribs 13... in this main body 11, Reference numeral 14 denotes a piece provided in each hole 12, and each piece 14 is biased in a direction protruding from the hole 12 by a spring 16 held by a baking plate 15.

The fitted state between the top 14 and the hole 12 of the switch body 11 has minimal play in the lateral direction and a sufficient gap in the vertical direction.

17 . . . are terminals, and 18 .

Reference numeral 20 denotes a channel selection bracket, and this bracket 20 has two horizontal ribs 21, 21, upper and lower, with an interval that allows the knob 18 to be inserted. The inner surface has protrusions 22 that make point contact with both the upper and lower surfaces of each knob 18, so that the contact area is reduced.

Therefore, the knob 18 is supported in the vertical direction by the projections 22, and in the vertical direction by the small gap between the top 14 and the inner surface of the hole 12.

The channel selection bracket 20 is attached to the television receiver escutcheon 23, and the front/face door 24 is also detachably attached to the escutcheon 23.

In this case, a hole 25 for protruding the knob 18 provided in the front door 24
Since the ribs 21, 21 of the channel selection bracket 20 fit into the holes 25, the knob 18 does not come into contact with the holes 25.

The tuning knob device of the electronic tuner of the present invention can be implemented as described above, and since the knob does not fit directly into the hole in the front door, there is no problem with the knob or minor turn caused by the door as in the conventional case. There isn't.

Also, the knob is shaped horizontally and linearly by the ribs of the channel selection bracket, resulting in an innovative design.
