DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a T-tape recorder
with a built-in pair of stereo microphones, which effectively prevents the inversion phenomenon
of the left and right sounds when the positional relationship between the operator and the sound
source is different. It is what you get. Tape recorder with stereo recording and playback
functions (a pair of left and right microphones (hereinafter referred to as stereo microphones).
When the recorder is built-in, the right and left sides at the time of recording and the right and
left at the time of reproduction may be reversed depending on whether the tape recorder Q is
opposite or l-7gi7 when the operator side has the effect W . That is, FIGS. 1A to 1B respectively
show an example in which the position with the above-mentioned operator sound source is
different when performing stereo recording using the portable tape recorder 1 with built-in
stereo microphone. First, in FIG. 1A, the input direction of the sound from the sound source to
the stereo microphones 2x and 2y of the tape recorder 1 (direction of sound transmission,
direction of arrow S) and direction operated by the operator (direction of arrow P) And
correspond to the case where stereo sound of the operator himself or his surroundings is
recorded. This has an advantage that, for example, in the recording of a conference, the person

on the left hand of the operator (recorder) and the person on the right hand can be clearly
identified at the time of reproduction. Therefore, the microphone 2X on the left corresponds to
the left channel (L channel) of the stereo and the microphone 2Y on the right corresponds to the
right channel (d channel) in the direction of the sound source and the operator (arrows S and P).
There is. The operation buttons such as the recording button 3 and the play button 4 are
disposed on the surface 6 of the integrated tape recorder 5 provided with the above-described
stereo microphones 2x and 2y, and the operation can be easily performed. However, as shown in
FIG. 1B, when the sound source and the operator are facing each other, that is, when the other
side is to be recorded, the direction S of the sound from the sound source is to be opposed when
recording Since the stereo microphones 2X and 2Y are arranged, the right side microphone 2Y in
FIG. 1 is arranged on the left side with respect to the direction of the operator (arrow P direction)
and the left side microphone 2X is arranged on the right side. Therefore, at the time of recording,
when a moving sound source such as a car or a steam locomotive moves from the left hand of
the operator to the right so as to avoid arrow t, sound is recorded from the microphone 2Y to 2X
Therefore, when this is reproduced, the sound source sounds to move from the right hand to the
left, and the phase is reversed. In addition, since the box with the operation pan of the tape
recorder case is disposed at a position where it is hidden from the author, it is inconvenient
because the user is forced to perform an operation by groping.
The present invention has been made to eliminate such conventional drawbacks, and at least one
of the surfaces of the tape recorder housing, on which the recording operation light is disposed,
and the one side To place the left and right microphones at an angle to the two sides on the
intersection line of the two sides so that sounds from the sound sources opposite to each other
on the two sides of the other side orthogonal to Therefore, even if the positional relationship
between the operator and the sound source during recording is different, the left / right
relationship or phase during playback is kept constant and superior, and the operation buttons
are easy to operate without being hidden from the operator side It aims to provide a stereo
microphone built-in type tape recorder that can be Hereinafter, preferred embodiments
according to the present invention will be described with reference to the drawings. 2 to 4 show
the first embodiment of the present invention, and FIG. 2 shows the case where there is a sound
source at the operator side, and FIG. 4 shows the case where there is a sound source at the
position facing the operator. . The stereo microphone built-in type 4-tape recorder 11 of the adz
embodiment comprises one surface 15 provided with operation buttons such as a recording
button 13 and a playnetan 14 among the surfaces of the tape recorder housing 12; A pair of left
and right microphones 20X and 20Y (that is, stereo microphones) are disposed on one side 17
where the surface 15 and another surface 16 orthogonal to each other intersect. These stereo
microphones 20X + 20Y are installed inclined with respect to the respective surfaces 15.16 so as
to be able to record sounds from the sound sources respectively facing the respective surfaces
15.16. This is merely inclined relative to the surface 15.16, as shown in FIG. 3, these surfaces
15.16 orthogonal surfaces 18 (and not shown in the figure) If the stereo microphones 20X and
10-05-2019

20Y are slightly inclined toward the left side or the right side, respectively, the degree of
separation of the left and right channels increases, which is preferable. In FIG. 3, the microphone
unit 21X for the L channel is formed to be inclined with respect to all of these surfaces at the
intersection 5-point of each surface 15, 16.18. It is installed and fixed on an inclined surface 22X
that faces slightly leftward, and a windscreen 23X is attached so as to cover the microphone unit
21X. Similarly, the microphone unit 21Y for R channel is installed and fixed on the inclined
surface 22Y facing slightly to the right, and the windscreen 23Y is attached so as to cover the
microphone unit 21Y.
When recording using the stereo microphone built-in type tape recorder 11 having the above
configuration, the direction of the operator (direction of arrow P) matches the direction of sound
from the sound source (direction of arrow S) In FIG. 2, the sound on the left side of the operator
(recorder) is recorded by the microphone 20X for the L channel, and the sound on the right side
is recorded by the microphone 20Y for the R channel. Therefore, these left and right stereo
microphones 20X. If one voice is recorded with 20Y and reproduced as it is with the left and
right speakers, for example, the voice of the person on the left hand of the operator is obtained
from the left speaker, and the voice of the person on the right is obtained from the one right
speaker. It is very useful when judging etc. In addition, since the operation buttons such as the
recording button 13 and the play button 14 face the operator, the operation can be easily
performed. Next, as shown in FIG. 4, when the direction of the operator (arrow P direction) and
the direction of the sound from the sound source (arrow S direction) face each other, the surface
on which the operation button is provided The surface 16 orthogonal to 15 may be directed to
the sound source. At this time, the left-right relation of the stereo microphones 20X and 20Y
viewed from the operator is changed, and the microphone 20X for L channel is disposed on the
left side of the operator, and the microphone 20Y for R channel is disposed on the right.
Therefore, if the sounds recorded by the left and right microphones 20X and 20Y are reproduced
by the left and right speakers as they are, for example, they move from left to right (see arrow
M). The sound source to be played sounds to move from left to right during reproduction as well,
and there is no phase inversion as in the prior art. In addition, since the recording button 13 and
the play button 14 are disposed on the surface 15 orthogonal to the facing direction 16 which is
hidden from the operator, the operation is easy while checking with eyes as it is. It is convenient.
Next, a second embodiment in which the present invention is applied to a stereo cassette tape
recorder will be described with reference to FIG. FIG. 5 shows a stereo cassette tape recorder 31
with a radio as a second embodiment, and among the surfaces of the tape recorder housing 32,
one surface 35 on which operation buttons such as the recording letter 33 and the play button
34 are disposed. And this-orthogonal to the surface, speaker 39L. A pair of left and right stereo
microphones 40X and 40Y are disposed on the intersection line 37 with the other surface 36
provided with the 39R and the like. ??????????????? 40Y is disposed at an angle
with respect to the surface 35.degree. 36 in the windscreen to record sound sources at positions
facing the respective surfaces 35.degree.

In such a stereo microphone built-in type tape recorder 31, when recording the sound source on
the operator side, the main body of the tape recorder 31 is laid, the arrow P, the direction of the
operator 81 in the direction 81, and the sound source You just have to match the direction of the
sound. In addition, when the sound source and the operator face each other, the operation may
be performed in the direction of arrow P2, and the sound in the direction of arrow S2 may be
recorded. Also in the second embodiment, similarly to the first embodiment, the sound source on
the operator side and the sound source facing the operator are recorded by changing the
arrangement of the main body of the tape recorder 31, and the phase is not reversed. ,
Reproduction can be performed in the state which maintained left-right relation. In addition,
when recording the sound source on the operator side, the recording user 33 is disposed on the
surface 35 facing the operator, and the ground surface 36 orthogonal to this surface is directed
to the sound source facing the operator However, the operator can easily confirm the recording
button 33 with his eyes, so that the user can easily operate the recording button 33 and can
prevent an erroneous operation. Further, as in the tape recorder 3a according to the third
embodiment shown in FIG. 6, the upper surface 431 of the tape recorder housing 32-the inclined
surface ? is formed between the surface 35 and the ground surface 36, On the inclined surface
43 (a pair of left and right stereo microphones 40X and 40Y may be installed. Furthermore, as in
the Thipre 9-Corg 31 of the fourth embodiment shown in FIG. 7, the tape recorder housing 32 is
inclined not only to the above-described surface 35 and ground surface 36 but also to both left
and right side surfaces. Slope 43X. A pair of 43Y is provided on the left and right, and their
inclination 1io43X. The stereo microphones 40X and 40Y may be installed on the 43Y. The other
configurations and effects of the third and fourth embodiments are the same as those of the
second embodiment, and therefore, the same reference numerals are given to the same portions
and the description will be omitted.
