Description

[Detailed Description of the Invention] The present invention relates to an indicator device for a television receiver using an electronic tuner.
The object of the present invention is to provide an indicator device that can display a VHF and UHF channel display pointer in a compact bracket and in a sharp line using light emitting diodes that emit light of different colors.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an exploded view of the moving body that constitutes the pointer. In the figure, 1 is a transparent case, which integrally has two fixing bosses 2 and 3. 4 is a metal mask having an elongated opening 5 in the center, 6 is a diffusion film, 7 is a lamp house, and a through hole 8 is in the shape of a lattice.
has. Reference numeral 9 denotes a printed board, on one side of which two light emitting diodes 10 and 11 of different colors are attached. For example, 10 is a green light emitting diode,
11 is a red light emitting diode.

The metal mask 4, the diffusion film 6, the lamp house 7, and the printed board 9 are sequentially fitted between the ribs 1a and 1b of the transparent case 1, and the bosses 2 and 3 are passed through the holes of each part, and one side of the printed board 9 is fitted. The tips of the bosses 2 and 3 appearing in the figure are welded to integrate each part.
At this time, the opening 5 of the metal mask 4 and the light emitting diodes 10 and 11 face each other through the through hole 8.

The present invention creates a pointer by making the light emitting diode 10, 11 emit light, for example, the green light emitting diode 10 emits light when receiving VHF broadcasting, and the red light emitting diode 11 emits light when receiving UHF broadcasting. That is, when one of the light emitting diodes 10 or 11 is made to emit light, the horizontally long minus-shaped pointer turns green or red due to the aperture 5 of the metal mask 4, and the transparent case 1
formed on top. Smoke panel 12
Display through.

FIGS. 2 and 3 show a state in which the moving body constructed as described above is assembled with a set. The smoke panel 12 is integrated into a notch of the escutcheon 13, and is arranged to face the transparent case 1. This smoke panel 1
Each on the escutcheon 13 on both sides of 2.
VHF channel number 14 and UHF channel number 15 are attached. Both channel numbers 14,1
5 may be printed in the same color, but may be printed to match the color of each light emitting diode 10, 11. The transparent case 1 is supported in a vertically movable manner by a guide 16 fitted in a groove between the ribs 1b and 1c, and is supported by a channel knob 17 shown in FIG. 3 and a variable resistor for generating a channel selection voltage (not shown). It is connected to a rotating shaft by a drive rope (not shown) or the like, and is moved up and down by rotating the channel knob 17.
At the same time, a channel selection voltage is applied to an electronic tuner (not shown) by the variable resistor.

Now, when the VHF/UHF switching knob 18 is operated to enable reception of VHF broadcasting, only the green light emitting diode 10 lights up and a green pointer 19 appears on the smoke panel 12. On the other hand, when the knob 18 is enabled to receive UHF broadcasting, only the red light emitting diode 11 emits light, and the red pointer 19 appears on the smoke panel 12.
appears. Here, as described above, if each channel number 14, 15 is printed in the same color as the corresponding light emitting diode, it can be easily determined which broadcast band is being received.

In FIG. 3, 20 is a power on/off knob, and 21 is a volume adjustment knob.

As described above, according to the present invention, VHF band, UHF band
The pointer is displayed in a straight line with different luminous colors depending on the band, making it easy to distinguish the display.
Each channel number is printed to match the color of the corresponding light emitting diode, so
It is possible to easily determine which broadcast band is being received.
