Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide an indicator device that can provide a bright and clear display using simple means.

FIG. 1 shows a conventional television indicator device, in which a lamp 2 is provided behind a disc type indicator plate 1, and a screen 5 provided on an escutcheon 4 is placed in front through a lens 3.

This device uses a lens 3 to magnify the display on the indicator board 1 and projects it onto the screen 5.
Although it has the advantage that it can be small, it has the disadvantage that the projected display is not clear and does not give a high-class feel.

Moreover, the lens system has a complicated structure, making it impractical.
There are various drawbacks such as difficulty in focusing on the screen 5.

The present invention aims to provide a device capable of producing a bright and clear display, and one embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, a plurality of square pyramidal truncated elements 6 are made of resin with good light transmission properties.

The sides of this element 6 are joined to form one frustum 7 as shown in FIG.

The smaller end face 8 of the frustum 7 is used as a display surface, and the larger end face 9 is used as a light irradiation surface.

This frustum 7 is attached as shown in FIG. That is,
In FIG. 4, 10 is the escutcheon or panel of the television receiver, 11 is the tuner, 12 is the tuning axis of this tuner 11, and 13 is the light receiving plate attached to the end face 9 of the frustum 7, which diffuses the light. Use a board that

Reference numeral 14 denotes a light source, which has one or two light sources such as neon lamps provided inside, and a semicylindrical reflecting mirror on the back thereof.

Reference numeral 15 denotes a display hole provided in the escutcheon or panel 10, and the display surface of the frustum 7 faces this hole 15.

Reference numeral 16 denotes a light control plate, which is transparent or translucent so that only the display portion 17 emits light, and is rotatably provided in front of the frustum 7 in FIG. 4.

A screen plate may be provided in the through hole 15.

Particularly when the display section 17 and the end surface 8 of the frustum 7 are transparent, it is better to provide a screen plate since there is no equivalent to a screen.

Further, the light control board 16 is provided with a plurality of ring-shaped display sections 17 and rotates in conjunction with the tuning shaft 12 of the tuner 1.

As described above, according to the present invention, the end face with the smaller area of the frustum is used as the display surface, and the end face with the larger area is used as the photothermal face, so the irradiated light converges and exits the display surface, making it brighter. A clear display can be obtained.

Further, since the frustum is constructed by combining a plurality of square pyramid elements, the display obtained on the display surface does not need to be uneven.

Also, since it is structurally sufficient to provide a simple frustum, it is simpler and more inexpensive to implement than conventional optical devices using lenses, and has high practical value.

Furthermore, since the light control plate is provided between the frustum and the display window, it is small.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of a conventional indicator device, FIGS. 2 and 3 are perspective views of some parts of the indicator device of the present invention, and FIG. 4 is a perspective view of an indicator device in an embodiment of the present invention. .

Claims (1)

[Scope of utility model registration request] A display hole is formed in a part of the escutcheon or panel, and the light control plate is arranged in the escutcheon or panel so that the part of the light control plate that rotates with the tuning axis of the tuner faces the display hole. A plurality of four frustum elements made of a material with good light transmission properties are combined to form one frustum, and the end face of the frustum with a smaller area is formed into a through hole for the above-mentioned display. The indicator device is arranged to face the inside of the light control plate so as to face the truncated cone, and to irradiate light onto a large-area end face of the truncated cone.
