Description

[Detailed Description of the Invention] This invention relates to a support device for a dial plate attached to a channel display section of a television set, etc.

Conventionally, a dial plate used for a channel display part of a television set, for example, is formed by printing the same number of numbers corresponding to the channel set number on a strip-shaped film sheet by printing or the like.
After cutting it out from the film sheet, it is attached in a predetermined arrangement to a separately manufactured frame-shaped support, and then this support is inserted into the position corresponding to the channel display part of the cabinet to display the channel. It was supposed to be set on the display. However, in such a conventional dial support structure, the dial and the support must be manufactured separately, and additional work is required to assemble the dial into the support. As a result, the number of component parts increases, the support structure becomes more complex, manufacturing costs increase, and installation is time-consuming.Furthermore, the film sheet after the dial is cut out must be discarded as it is. Since this is common, there was a problem in that material was wasted when manufacturing the dial.

This idea was made in view of the above points, and it integrates the dial and the band-shaped sheet that forms it.
By using this band-shaped sheet itself as a support for the dial, it is possible to reduce the number of component parts, simplify the dial support structure, and reduce production costs, and eliminates the need to assemble the dial to the support. To facilitate the installation of a dial plate and to facilitate the replacement and replacement of a dial plate.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the main support device, in which character display parts 12 of the same number as the number of channels are arranged along the longitudinal direction of a belt-like sheet 10 having a predetermined width so that they are at the same position as the channel display position. They are integrally formed at predetermined intervals. This belt-shaped sheet 1
0 is formed in the form of a slightly elastic film made of vinyl chloride resin, polyester film, etc., and has an extra length 11 at one end, and by holding this, the TV set can be easily attached to and detached from the cabinet. It's becoming like that.

The character display portion 12 is formed so as to be integral with the belt-shaped sheet main body 100 and to be able to be cut out from the main body 100. As shown in FIG. 2, this character display section 12 has a substantially rectangular shape, and has protrusions 121, 121 on two opposing sides along the longitudinal direction.
A slit 13 of a predetermined width is formed along the periphery of the slit 13 to separate it from the main body 100. The character display portion 12 is formed in a cross-linked manner across the slit 13 at two locations approximately at the center of two opposing sides along the width direction of the strip-shaped sheet 10 and at two locations approximately at the center of the edges of the protrusions 121, 121. The seat body 10 is connected by a connecting portion 122 provided in the
0 and this connecting portion 12
2, it can be cut out from the band-shaped sheet 10.

On the character display section 12, a number A corresponding to the channel set number is punched out by printing, painting, or the like. That is, the part marked with the number A is transparent or has the same color as the background color of the strip sheet 10 so that light can pass therethrough, and the other parts are printed or painted 15 with black or the like so that no light can pass through. There is. Note that instead of this, the numeral A itself may be displayed in color, with the surrounding area being the background color. In this embodiment, since the band-shaped sheet 10 is a transparent body, there is a risk that light leakage may occur when light is irradiated from behind. In that case, the band-shaped sheet 10 is made opaque so that no light passes through it,
Alternatively, it may be printed or painted black.

On the other hand, the opening 16 formed after the character display section 12 of the band-shaped sheet 10 is cut out is as shown in FIG.
As shown in FIG. 3, like the display section 12, it has a substantially rectangular shape, and two
Recesses 161, 161 are provided at positions corresponding to the protrusions 121, 121 on the sides. A replacement dial 20 is attached to this opening 16. This dial plate 20 is provided in advance for each channel set number simultaneously and separately when, for example, the character display section 12 is formed on the band-shaped sheet 10, and has a substantially rectangular shape as shown in FIG. , protrusions 200, 200 that engage with the recesses 161, 161 of the opening 16 on two sides along the longitudinal direction of the belt-shaped sheet.
is installed protrudingly.

The outer shape of the dial 20 is slightly larger than the opening 16, and the distance between the edges of the recesses 161, 161 of the opening 16 is L, and the distance between the two sides along the longitudinal direction of the dial 20 is L'. , the relationship between the two is set so that L'>L. On this dial 20,
In the same manner as described above, the number B corresponding to the channel set number is punched out by printing or painting.

When replacing one of the character display parts 12 from the belt-like sheet 10 with the dial plate 20, by cutting out the connecting part 122 of the character display part, this character display part 12 can be removed from the belt-like sheet 10. It is easily cut out, and then the replacement dial 20 is attached to the protrusions 200, 200 and the recesses 161, 161.
When the dial 20 is inserted into the opening 16 by engaging the two, the dial 20 is slightly curved and bulged outward due to the above-mentioned dimensional relationship L'>L, as shown in FIG. Attached to 10. According to this, the character display part 12 can be cut off by simply cutting out the connecting part 122, and the dial plate 20 can be cut off by simply cutting out the connecting part 122, and the dial plate 20 can be
Since it can be attached to the belt-shaped sheet 10 with just one touch by simply engaging 00 with the recesses 161, 161, the character display part (which also constitutes a dial plate)
12 and the dial plate 20 can be exchanged very easily. Moreover, due to the curvature due to the above-mentioned dimensional relationship L'>L, a force is constantly applied to the dial 20 due to its elasticity to return to the flat shape, and the opening is formed between the edges of both sides and the protrusions 200, 200. Since the edge portions of both sides along the longitudinal direction of the holder 16 are held while being pressed from above and below, a more reliable and strong attachment can be expected.

The strip-like sheet 10 integrally having the required number of character display sections 12 as described above is mounted at a mounting position provided at a predetermined position in the cabinet of a television set, that is, at a channel display position, as shown in FIG. .

In the figure, reference numeral 30 denotes a cabinet of a television set, and a window 300 is formed at a predetermined position on the front surface of the cabinet 30, and a locking stepped portion 301 for locking and holding the strip sheet 10 along both inner surfaces of the window 300; 302 is formed, and a slit 303 into which the band-shaped sheet 10 is inserted is opened along the vertical direction at the base end of one of the locking steps 301. On the front side of the window 300 of the cabinet 30, there are a required number of display windows 3 for displaying channel numbers.
A lid 31 having 10 .

A printed circuit board 32 is installed at a predetermined distance from a window 300 on the back of the cabinet, and a light emitting body 33 such as a pilot lamp or LED is supported in a holder 34 on this printed circuit board so as to correspond to the channel number display position. is installed.

Then, the belt-shaped sheet 10 has the above-mentioned slit 303.
Each character display part 12 is shown on the back side of the window 300 through the window 300.
is inserted so that it is at the same position as each display window 310 of the lid 31, that is, at the same position as the channel display position,
It is held between the locking steps 301 and 302 and attached to the cabinet 30. At this time, the extra length 11 is held by the slit 303, and its elasticity urges the tip of the band-shaped sheet 10 toward the back of the cabinet, so that the band-shaped sheet 10 is held in close contact with the back of the window 300. This allows for more reliable installation.

Thus, by simply inserting the strip sheet 10 itself into the back surface of the window 30 of the cabinet 30, each character display section 12 can be easily set at a position corresponding to the channel display position. Thereafter, by performing appropriate channel operations, the corresponding character display section 12 is irradiated with light from the back side by the corresponding light emitting body 33, and the corresponding channel number becomes visible through the display window 310.

In addition, in the embodiment, the recess 16 is provided in the opening 16.
1,161, and the dial 20 has a protrusion 200,2
00 is provided, but instead of this, an opening 1 is provided.
6 may be provided with a protrusion, and the dial 20 may be provided with a recess, and furthermore, these protrusions or recesses may be provided in the width direction of the strip sheet 10, instead of on the two longitudinal sides of the strip sheet 10 shown in the embodiment. It may also be provided on two sides along the line.

As explained above, according to the present dial support device, the dial and the band-shaped sheet forming the dial are integrated, and this band-shaped sheet itself is used as the support for the dial, so it is different from the conventional one. This eliminates the need for a support frame for supporting the dial, reduces the number of component parts, simplifies the dial support structure, and reduces manufacturing costs. Furthermore,
There is no need to assemble the dial plate into the support frame as in the past, and the dial plate can be easily set by simply inserting the strip sheet itself into the channel display section of the TV set, making installation easier than before. It can be done extremely easily and reliably. In addition, by using the band sheet itself as a support for the dial, the remaining part of the band sheet after cutting off the dial, which was previously discarded, can be used, eliminating material loss during dial manufacturing and making effective use of materials. can be achieved.

Moreover, according to this invention, the replacement dial plate can be reliably and easily attached with almost one touch by simply inserting the replacement dial plate into the opening formed after the character display part of the band-shaped sheet is cut out. It has the advantage that the dial plate can be replaced extremely easily.
