DETAILED DESCRIPTION OF THE INVENTION The present discussion is concerned with an
adaptation that displays the output of each channel of a two-channel or four-channel stereo
reproduction device so that + M, 'can be compared to-. For this purpose, it has been proposed to
juxtapose juxtaposed lamps of varying brightness at the output of each channel, so that it is not
possible to display fine output differences. Therefore, although a can-like light emitter has been
proposed in which the length of the light emitting part is changed according to the output of
each channel (1), this has the disadvantage that the structure is complicated . The present
invention aims to be simple in structure and to allow the output to be displayed with the length
of a light band. Hereinafter, the present invention will be described with reference to the
illustrated embodiment. Reference numeral 1 denotes a display panel, which warms the front
opening of the light-transmissive case 6. The case 6 is divided into four compartments by crossshaped partitions, in each of which a lamp 2.3, 4.5 is arranged. The 77Fl to each lamp 2, 3 and
4.5 is given by splitting the human power to each speaker 7.8, 9.10 which performs 4-channel
stereo reproduction, and the brightness according to the output of each channel The abovementioned lamps are arranged at the four corners of the display board 1 and irradiate it from
behind. The display panel 1 is made of a transparent or translucent material, and on the back
surface thereof, concentric grooves 11 as shown in FIG. Figure 4 shows the cross-sectional shape.
(2) When each of the lamps 2 to 5 is lit at a brightness corresponding to the output of each

channel: 1 ′ ′, the light strikes the groove 11 on the back surface of the display panel 1. When
this is observed from the surface of the display panel 1, it can be seen as four triangular light
bands 12 to 15 as shown in FIG. And if the light quantity of each lamp 2-5 increases, the length
of the belts 12-15 of light will corrode accordingly. Therefore, by comparing the lengths of the
light bands 12-15, the volume difference of each channel can be 'f [I' in the vision 11'1. In the
figure, the volume of the speaker 10 is the smallest, and the volume of the speaker 7 is the
largest. Behind the display board 1, 冴! 6: When the screen 17 provided with the triangular
window 16 shown in FIG. 1 in the radiation method is provided, the light bands 12 to 15 become
clearer. The figure of the display board 1 may be a combination of concentric circles with centers
of the four corners, as shown in FIG. 1, if the lamps 2 to 50 are in the four (3) corners of the
display 1 as described above, the light bands 12 to 15 are directed toward the center with the
four corners of the display panel 1 as the base end. When the installation positions of the rungs
2 to 5 are collected at the center as shown in FIG. 8, the rungs extend and retract outward with
the center at the proximal end.
Fang 9 is a display state in the case where the lamps 2 to 5 are arranged at the center 12 and the
figure of the display plate 1 is shown in FIG. 7. As described above, the present invention is
provided with a transparent plate having concentric solid grooves although the configuration is
substantially the same as that of the display-T depending on the brightness of the conventional
lamp. It can be displayed not as a difference in brightness but as a difference in the length of a
light band.
