DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an xh microphone
built-in type tape recorder. In general, it is well known that a tape recorder equipped with a
microphone uses a nondirectional microphone, which is fixed at 6 so as to be exposed from a
110 plate of a cabinet constituting the tape recorder. By the way, when recording using the
above-mentioned microphone in the above-mentioned tape recorder when recording many
people's voices like L1 meeting (this is because it is the above-mentioned microphone or nondirectional one.? Whether you can record the city of people who are in a wide range, or a nondirectional microphone, although it has a certain degree of directivity и ?do?, it is other than its
pointing direction (If you want to record the voice of the person, use the microphone The tape
recorder main unit had to be moved to point it in that direction, which was extremely
inconvenient. As described above, when recording using a microphone, the tape recorder
described above has advantages and disadvantages depending on its use purpose. The fourth
proposal is to provide a microphone-in-the-wall-type tape recorder which solves the drawbacks
as described above. The in-microphone tg type tape recorder according to the present invention
will be described below with reference to the drawings. In the figure, 1 is a cabinet in which a
tape recorder is slotted, 2 is a speaker attached to the front plate 1a of the cabinet 1, 3 is for
recording, playback and stop + L attached to the top plate 1b 2, various rewind buttons for back
feeding 2, 4 is a cassette insertion portion formed on the front plate 1 a, 6 is a volume
adjustment knob attached to the shingling plate 1 c of the cabinet 1, 6 is a microphone storage
portion It is. The microphone storage section 6 is as shown in FIG. 2 and FIG. ) 5 is composed of a
j01 portion 21 formed on the top plate 1b of the cabinet 1 and a microphone storage case 24
pivotally supported by four portions 21 in a freely accessible manner. The bottom surface 22
constituting the four parts 21 is formed so as to protrude into the bearing part 23 or the four
parts 21 [The size of the microphone part 24 is set in the through hole 25 formed in the bearing
part 23] The provided shaft portion 26 is inserted freely up and down. The microphone lens case
24 is composed of an L case 24a and a lower case 24b. Reference numeral 27 is a rib 28a which
is stored in the microphone storage case 24 and formed in the upper case 24a. 29a and L7iLf)
rib 28b in% case 24b.
29b is a single-fingered microphone held by and 29b. The microphone 27 is held so as to face
the through holes 30 (... (... Of composite plates made by cedar) by the front surface plate 24cQ
of the microphone storage case 24 and the surface portion 27a of the front end 27b. A reference
numeral 31 denotes a steel ball having a through hole 32: C inserted '1' formed in the L child
bearing 23. The steel ball 31 is inserted into the bearing 23 by a flat sheet 33 and a flange 1 par
16. The direction / biasing force of the pivoted shaft 26 is configured to be given. ?????
When the recording shaft portion 26 is formed on the circumferential surface and is stored in the
microphone storage case 24 or the recessed portion 21, the L steel ball 31 or the first groove is
also fitted, and 35 is a-[- The second groove is formed on the lower side of the shaft portion 26
and fits into the steel ball 31 when the microphone storage case 24 is pulled out from the recess
21. An upper fitting metal fitting 36 is fitted to a groove (not shown) formed on the lowermost
four members G of the shaft 26 and the upper fitting 37 is formed on the side plate 1c of the Lshaped chassis 1. The plurality of through holes are respectively made to face the plurality of
through holes 30 formed on the front plate 24 CE of the microphone 24 when stored in the
microphone storage case 24 or the four portions 21. It is configured. The other part of the cord
line 27 c of the microphone 27 is formed on the rear plate of the microphone storage case 24.
21 and a through hole 39 formed by a two-sided surface 2tJ are connected to the electric circuit
portion of the recorder 7) recorder. ! <?1: The side plate 24 d of the microphone storage case
24 is also formed with a through-hole 40 of Confucianism. In addition, the ? -directional
microphone 27 used here is a diaphragm made of a sound signal from the side surface 27d of
the front end 27b other than the blind first row 27a, On both sides: The sound signal from the
side is modulated by f-type by being obtained G1--or I'l, and it is slotted so as to be more
directional or stronger. Therefore, as described in the toe, the microphone storage case 24? The
gate portion 21 (in the state book where the storage f 'is stored, the 11111' jj portion 27a of the
mid-directional microphone 27 or the microphone storage case 24) Blood plate 24c и Fixedly bite
through-hole 30 and through-hole 37 formed on side 1c of cabinet 1 with 1 counter L1 cabinet 1
of 1 (7 fIs from the direction of 1 board 1 c Do.
The seven-sided, the side of the side portion 27d of the end of the one-finger microphone 27: 1:
2 of P note + does not feel the sound processing, so the short-directional microphone is one side
of the diaphragm Sound IE or 1111 will be changed by the noise. As shown in FIG. 4 curve 8a,
the microphone 27 itself has directivity or gentle characteristics. On the other hand, when the
microphone storage case 24 is projected out of the recess 21, it is formed not only in the
direction of the through hole 30 formed in the front plate 24c of the microphone storage case 24
but also in the one surface plate 24d. Also from the direction of the through hole 40 + '51 E! J [L

becomes a thing. Further, when the microphone storage case 24 is recessed and pulled out from
the portion 21, 1 a steel ball 31 in which a second strip groove 36 formed in the shaft portion 26
of the microphone storage case 24 is biased by a plate spring. The microphone housing case 24
(FIG. 2 and FIG. 3, dotted line (shown by 1 in FIGS. 2 and 3) is held and held. Then, the
microphone 4 or the receiving case 24 or @@ is rotated about the pivot 26 so that it can not be
stored inside the Z-like directional microphone 27 as shown in FIG. 4 curve b ', brr, bHL:.
Depending on the direction of its directional characteristics, you can choose sand. In the
embodiment, when the microphone 27 is housed in the microphone storage case 24 or the four
parts 21 of the chassis 1, the front plate 24c or the side plate 1c of the cabinet 1 is opposed to
the unidirectional plate 27c. In addition to this, the front plate (the front i portion of the
microphone 27) 24c of the microphone storage case 24 is opposed to the front & 1a of the front
cover 1c. The effect of an intermittent effect can be exhibited also in the one configured by
adding 7 flh or so from one direction to the hole 30 or the through holes of the plurality
provided in the front plate 1a. As described above, the Table Fooder of the present invention
allows the microphone storage case to be freely inserted into and removed from the cabinet, and
can be rotated when drawn (7C is approximately 0 so that the upper surface of the storage case
and the surface of the cahi not substantially coincide) In addition to moving in and out of the
upper storage case, + C (in conjunction with crushing 10 so as to change the directional
characteristics of the microphone, it is possible to completely store the microphone storage tray
in the cabinet). Because it can be removed, there is no part protruding outside + C at the time of
storage and the appearance is preferable 10, there is very little risk of damage to the
microphone, and the microphone storage case is pulled out from the recess of the cabinet and
rotated You can select the direction of the stored microphone as a sandblast within a range of
360 Therefore, when you want to emphasize the voices of many people individually in case of
meeting and want to record individually, it is possible to record by rotating the microphone
storage case without moving the cabinet, and it is extremely easy to use. It is a thing.
In addition, since the microphone storage case is moved in and out by the shaft portion provided
in the microphone storage case and the bearing portion in the four portions inserted from this
shaft, reliable clamping can be achieved for the configuration or the portion.? ?
