[Detailed Description of the Invention] In the present invention, when reproducing four separate
audio signals, such as a 4-channel record, a 4-channel tape, etc., the reproduction status of the
volume of these four audio signals can be seen at a glance. It is about the 4 channel indicator to
make it understand, and it is a house. An indicator for four channels according to the present
invention will now be described with reference to the embodiment shown in the drawings. 1 and
2 are the meter parts, 1 is a fixed part, 2 is a rotating coil frame having a coil 3 as a rotating part,
and the rotating coil frame 2 is shown in FIG. Such a cylindrical cylindrical index part 4 is
attached, and the semi-cylindrical index part 4 is provided with, for example, a pattern of a
plurality of arc-shaped slits 5 juxtaposed as shown. As shown in FIG. 4, the meter 6 provided with
such a semi-cylindrical index portion 4 is appropriately combined and disposed of the four, and
the front surface is covered with the screen 7, and further shown in FIG. As described above, the
lamps 8 are disposed on the back surface of each of the semicylindrical index portions 4
described above, and the light of the lamp 8 is irradiated to the back surface of the
semicylindrical index portions 4. A light shielding plate 9 is divided into each channel to prevent
the light of each lamp 8 from leaking to other channels. Now, in Fig. 5, when no current flows in
each of the meters 6, if the arcuate slit (2) 4J of the semi-cylindrical index portion 4 is made to
exist between A and B, the current in each of the meters 6 Flows, and the semi-cylindrical index
portion 4 rotates as an arrow, and accordingly, the light of the lamp 8 passes through the arcshaped slit 5 and is projected on the screen 7 in a state of being divided into four. When the
position of the arcuate slit 5 is between AC, the entire shape of the arcuate slit 5 is projected on
the screen 7 to indicate the current maximum, ie, for example, the volume maximum. Thus, when
the current flowing to the meter 6 is different for each channel, the state as shown in FIG. 6 is
displayed on the screen 7 accordingly, and the volume increase / decrease state of each of the
four channels is one On the screen 7 of FIG. 7 shows another embodiment in which projection as
shown can be performed on the screen 7 by selecting the combination arrangement of the semicylindrical indicators 4 described above. In the present invention, as described above, a semicylindrical index portion provided with an arc-shaped pattern (3), etc. is attached to each of the
rotating coil frames of four meters, and these four one-square meters are By providing an
indicator for 4-channels in which the lamp light is irradiated from the back surface of the semicylindrical index portion by appropriately arranging in combination, each signal reproduction
state can be divided at a glance on one screen. There is a feature, and since four meters and the
like are intensively arranged in this way, there is an advantage that a part of the indicator does
not take a place. .
