Tape type echo device
3. Detailed description of the invention According to the present invention, the tape echo device
according to the present invention, the stone channel output terminal and the echo signal by the
stone channel voice signal from the channel output ladder and the echo signal by the twin
channel voice signal are alternately repeated at the same time. It is an object of the present
invention to provide an echo apparatus t-capable of emitting an echo signal three-dimensionally
and nine-dimensionally in an arrangement for emitting an echo signal so as to increase an Il field
feeling. Fig. 1 shows a block diagram of an example of a conventional tape-type echo apparatus
as T-shaped. In the same figure, the audio signal coming from input ladder 1 is a line! , As well as
being taken out as a normal signal to the output camera 2 via t-. After being amplified by the
recording amplifier 6, EndPage: 1 is sent to the recording head 4, and it travels in the direction of
arrow a, and the recorded signal is erased by the erasing head 9 and recorded on the endless
magnetic tape 5 removed. The audio signal (normal signal) recorded on the magnetic tape 5 is
reproduced by the reproducing head 6 and is outputted as an echo signal 9 to the output
terminal 2 through the reproduction equalizer 7 and the amplifier 8 and the line signal 2 is The
data is recorded on the magnetic disk 15 by the recording head 4 via the recording head 4. At
this time, the echo signal is delayed in time from when the normal signal is recorded by the
recording head 4 to when it is reproduced by the reproducing head 6. The first echo signal
recorded by the recording head 4 is reproduced again by the reproduction head 6 and taken out
from the output circuit 2 as a second echo signal with a predetermined time aI # IJ and time as

described above. By repeating the above operation, the echo signal is repeatedly extracted
several times. However, in this conventional tape-type echo device, since the echo signal is
merely planarized with a time delay, a reverberation effect with a large hole of 2% at 1%, such as
five layers of imaginary In the present invention, the above-mentioned drawbacks have been
eliminated. The present invention will be described with reference to the second and the
following embodiments. FIG. 2 shows a block system of one embodiment of the tape type echo
apparatus according to the present invention, which is T-shaped. P is in the figure. Channel back
door signal is line when it comes in from input terminal 10! The signal is taken out as a normal
signal as it is to the pressure channel output maze 11 as it is, and is amplified by the recording
amplifier 12 and travels in the direction of arrow 1: lJa by the pressure channel recording head
13 and already described by the erasing head 25. ! The signal is erased and an endless magnetic
tape 14 is pressed onto the track and core recorded on the track.
-10,000, stone channel audio signal coming in from input tide 15 is a line! . The signal is taken
out as it is as a normal signal to the stone nayanner i male terminal 16 'as it is and amplified by
the recording amplifier 17 and then recorded on the stone channel track of the magnetic tape 14
by the right channel recording head 18. '. The audio signals (normal signals) of five channels
recorded on the left channel track of the magnetic tape 14 are reproduced by the pressure
channel channel head 19 and frequency-compensated by the channel equalizer 20, and then the
interlocked switch 8.. Terminal a and the terminal of the switch 82. It is taken out as a first left
channel echo signal to the stone naginnel output forceps 16 through the amplifier 21 and is
recorded on the magnetic tape 140 stone channel track by the stone channel recording head 18
via the line. At the same time, the sound signal (normal signal) of the rock channel recorded on
the rock channel track of the magnetic tape 14 is generated by the rock head of the rock head 22
and the frequency is reproduced by the reproduction equalizer 23. After compensation, the
terminal a of the switch S2 and the terminal b of the switch S, the amplifier tiF 24 is blocked and
the left channel output ladder 11 is given the first stone channel echo compensation number 9
and the line ! , And is recorded on the pressure channel track of the magnetic tape 14 by the five
channel recording head 1S. That is, the first pressure channel echo signal is taken out to the
stone channel output maze 16, and at the same time the first stone channel echo signal is
outputted to the channel output maze 11. On this occasion. The pressure channel echo signal is
delayed in time from when the five channel normal signal is recorded by the channel recording
head 13 to when it is reproduced by the pressure channel reproducing head 19, and in the same
manner, the stone remote echo signal is The stone channel recording head 18 delays the time
from when the stone channel normal signal is recorded to when it is reproduced by the stone
channel re-maining head 22, and then it is output 9. Next, the first and channel echo signals
recorded by the stone nayannel recording head 18 are produced now by the stone nayannel
reproduction head 22 and, similarly to the above, through the reproduction equalizer 23, the
switches 8 and 81, and the amplifier 24. And it is output as a second pressure channel echo
signal to the channel output maze 11 and the line! 6 and recorded by the channel recording head

15 on the pressure track of the magnetic tape 14.
At the same time, the first stone channel echo signal recorded by the pressure nayan EndPage: 2
channel bell head 1'3 is reproduced by the pressure channel reproduction head 19, and in the
same manner as described above, the reproduction equalizer 20. The switch s, s2, through the
amplifier 21 to the stone channel output ladder 16 is sent out as a second stone channel echo
signal and the line 9, along with the line! , Through a stone channel recording head -18 is
recorded on the stone nayannel track of the magnetic tape 14. # 2, the second pressure channel
echo signal is at pressure channel output terminal 11. At the same time, the second stone
channel echo signal is sent out to the stone nayanner output tide 9 and 9. Next, the second stone
channel echo signal recorded by the single stone channel recording head 18 is reproduced by the
stone channel reproducing head 22 and is applied to the pressure channel output terminal 11
three times in the same manner as described above. Along with being sent out as stone channel
echo signal of the eye. And recorded on the magnetic tape 14 by the Tyanner head 13-0 At the
same time, a signal is sent to the left left channel of the second left channel recorded by the
channel recording head 13 and played back to the left channel playback head 19 In the same
manner as described above, it is taken out as a third left channel echo signal at the stone channel
output terminal 16 and is recorded on the magnetic tape 14 by the one-stone channel recording
head 18. That is, the left channel echo signal of the third time is taken out to the stone channel
output terminal 16 as well as the first time, and at the same time the third channel echo signal is
outputted to the left channel output tide 11 like the first time. Be By repeating the above
operation, the stone channel echo signal and the channel echo signal are alternately alternately
repeatedly output from the left channel output terminal 11 and the stone channel output
terminal 16, respectively. For this reason, the echo signal is not simply output 9 flatly with a time
lag as in the conventional example, but stone channel echo signal and pressure channel echo 1
are extracted three-dimensionally alternately from the left and right, especially a large hole. As in
the case of the reverberation effect, it is possible to obtain an effect that echoes are alternately
reflected from the ridges of the five layers. Incidentally, if the movable contacts of the switches
81 and 8 □ are connected to the ladder bKil ', the pressure channel echo signal is taken out only
to the pressure channel output terminal 11, and the stone channel echo signal is obtained only to
the stone channel output tide 16. Nine channels can be output, and five channel echo signals and
stone channel echo signals can be output simply as pressure channels and only stone channels.
As described above, the tape type echo apparatus according to the present invention outputs the
pressure channel audio signal as it is to the pressure channel output terminal and means for
recording on the magnetic tape with the pressure channel recording head, and the stone nayan
nel audio signal As it is taken out to stone channel output ladder as it is and means for recording
on magnetic tape with pressure channel recording head, and the signal recorded with pressure
channel recording head is reproduced as stone echo channel as echo signal. Furthermore, means

for recording this echo signal on a magnetic tape with a stone channel recording head, and the
signal recorded on the stone channel recording head is now generated and taken out as an echo
signal to a pressure channel output ladder and this echo signal is further left channeled. Since the
recording head is a means for recording on a magnetic tape, The echo signal by the rock channel
audio signal and the echo signal by the left channel audio signal can be alternately and
repeatedly taken out alternately at the same time, so that the echo signal can be simply In
addition to being emitted, it is possible to obtain an effect such that echoes are alternately
reflected from the wall of the stone, such as a reverberation effect particularly in a large hole,
taken out three-dimensionally in the stone. Compared with the conventional example, it has
features such as being able to increase the sense of reality.
