Description

[Detailed Description of the Invention] This invention relates to a tape recorder having a detachable stereo microphone unit.

Generally, portable cassette tape recorders have either a built-in monaural microphone or a built-in stereo microphone.

Conventionally, in addition to a monaural microphone, an external microphone is detachably connected to a small cassette tape recorder via a microphone jack and a connection cord. This external microphone is separate from the main body, making it less portable, and the exposed connection cord impairs the aesthetics.

In order to solve this problem, it has been devised to provide an external microphone detachably attached to the main body of the tape recorder. In this case, if the stereo microphone unit is attached to the side where the control section is located, there is a risk that the operation function of the control section will be significantly impaired.In order to avoid impairing the operation function of the control section, attach the microphone unit to the side where the control section is not located. There is a need to. For example, if the microphone unit is attached to the bottom surface where there is no operating section, impact force is particularly likely to be applied to the microphone unit, and the durability of the microphone will be significantly impaired.

Also, when you point the microphone unit at the object to be recorded, each operation mode (e.g. record, playback, stop) will be activated.
Since the operating positions of the operating buttons, pause switch, etc. are in the opposite direction, there is a drawback that the operability is significantly impaired.

This invention was made in order to eliminate the above-mentioned drawbacks.A stereo microphone jack is provided at least on the side of the cassette tape recorder body where the pause switch is disposed, and a stereo microphone unit is detachably attached to this jack. To provide a tape recorder that can be easily mounted on the operation surface of a tape recorder main body without impairing the operation function of the tape recorder main body by providing a microphone unit with an external operation section corresponding to at least a pause switch. It is something.

An embodiment of this invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a tape recorder main body with a built-in stereo circuit, and a cassette chamber 2 into which a microcassette tape is loaded and a speaker 3 are arranged on the front panel of the main body 1.
Also, on the left side of the main body 1 are various operation mode operation buttons,
For example, recording (REC) operation button 4a, playback (PLAY)
An operation button 4b and a stop (STOP) operation button 4c,
A stereo headphone jack 5 and an external power jack 6 are provided. Furthermore, an omnidirectional microphone 7 is mounted on the upper side of the tape recorder main body 1.
, a pause switch 8, and a volume knob 9 are provided. A microphone jack 10L for the L (left) channel and a microphone jack 10R for the R (right) channel are disposed on at least the side surface of the cassette tape recorder main body 1 on which the pause switch 8 is disposed, in the illustrated example, on the upper side surface. do.

On the other hand, the microphone jack 10R, 10
Detachable stereo microphone unit 1 in L
1 will be provided. Condenser microphones 12R and 1 are connected to both ends of this stereo microphone unit 11.
2L, and a pair of connection plugs 13R, 13L are provided on the mounting surface in correspondence with the microphone jacks 10R, 10L. This microphone unit 11 is provided with an external operation section corresponding to at least the pause switch 8. For example, as shown in FIG.
Rotatably provided. One end of this seesaw lever 14 is provided to protrude from the operation surface of the microphone unit 11. Further, the other end of the seesaw lever 14 is set inward from the mounting surface of the microphone unit by the protruding dimension of the operation button so as to be connected to the operation lever of the pause switch 8.

In addition, as shown in FIG. 3, the seesaw lever 14
In addition, a disk-shaped connection knob 15 is rotatably provided on the microphone unit 11 in correspondence with the volume knob 9. At this time, a part of the connection knob 15 is provided so as to protrude from the operating surface of the microphone unit 11, and the mounting surface of the microphone unit 11 is provided so as to mesh with the volume knob 9 when the microphone unit 11 is mounted on the tape recorder main body 1. It is provided so as to be positioned further inward by the protruding dimension of the volume knob 9.

Next, the operation of this invention will be explained.

Now, when the microphone unit 11 is attached to the tape recorder body 1 for stereo recording, the seesaw lever 14 is connected to the pause switch 8 as shown in FIG. 2, and the volume knob 9 is connected to the pause switch 8 as shown in FIG. The connection knob 15 meshes.
When the seesaw lever 14 is rotated left and right in this state, the operating lever of the pause switch 8 responds to this rotational force and is turned on and off. Furthermore, when the connection knob 15 is turned, the volume knob 9 responds to this rotational force and the volume is adjusted.

Therefore, the cassette tape recorder body 11
Microphone unit 11 is removably attached to the operation surface of the
In addition, this microphone unit 1
By providing an external operating section in 1 corresponding to the pause switch 8 and volume knob 9, it is possible to easily attach the microphone unit 11 to the operating surface of the tape recorder main body 1 without impairing the operating functions of the tape recorder main body 1. As well as being able to
The connection cord can be removed, improving aesthetics and portability.

In addition, by mounting the microphone unit 11 on the operation surface of the tape recorder main body 1,
Even when the microphone unit 11 is directed toward the object to be recorded, the operation section does not turn over as in the conventional example, so that operability is not impaired. Also, since impact force is less likely to be applied to the microphone unit, durability is improved compared to conventional microphone units that are mounted on the bottom.

Note that this invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without changing the gist.

For example, in the embodiment described above, a seesaw lever was attached to the microphone unit so as to be rotatable in correspondence with the operation mechanism of the pause switch, but in this invention, the lever can be connected to the pause switch and the pause switch can be operated from the outside. If so, the present invention is not limited to this, and for example, a push button may be provided on the microphone unit so as to be slidable back and forth so as to be connected to a push mechanism of a pause switch.

As described above, according to this invention, a stereo microphone jack is provided on the side of the cassette tape recorder body on which at least the pause switch is disposed, and a stereo microphone unit is detachably attached to this jack, and at least the pause switch is attached to the microphone unit. By providing an external operation section corresponding to the above, it is possible to provide a tape recorder that can be easily mounted on the operation surface of the tape recorder main body without impairing the operation function of the tape recorder main body.
