The antenna 19 is for transmitting an audio signal to a receiver (not shown), and transmits this signal to the speaker 32 through an amplifier (not shown).

FIG. 2 shows a remote control integrated microphone 1a.
3 is a circuit diagram of the image input device 40, and includes a remote control unit 9 for remote control operation of the image input device 40 and a microphone unit 10 to which the voice of the speaker 31 is input.

The power switch 2 is, as described with reference to FIG.
When turned on, both the remote control unit 9 and the microphone unit 10 are brought into conduction.

The remote control unit 9 is an L remote control transmission unit.
ED62 and LED driver 12 for driving the LED62
And the microcomputer 1 for controlling the LED driver 12 by receiving a signal from the forward feed switch 5 or the backward feed switch 6.
It is composed of 3.

The microphone unit 10 has an angle detection sensor 15 having a built-in switch that conducts electricity when the longitudinal direction of the remote control integrated microphone 1a is set to a horizontal tilt angle of 70 degrees. Note that the angle of 70 degrees is taken as an example, but of course, other values may be used depending on the situation of the situation, and the angle detection sensor 15 is configured to be adjustable in angle to obtain an optimum value according to the situation. You may make it set.

In addition, the battery 14 which is the power source of the microphone unit 10, the voice input unit 61 (a capacitor in this case) through which the speaker inputs voice through the cover 3, the differential amplifier 16 for amplification, and the modulation circuit 17. I am configuring. Both batteries 11 and 14 may be shared.

FIG. 6 shows an overall configuration of a presentation using the remote control integrated microphone 1a of the present invention, the image input device 40, the monitor 33, and the speaker 32.

In the above structure, the microphone unit 10 is a wireless condenser microphone in this embodiment, but any microphone may be used as long as it is a general microphone.

Also, a remote control integrated microphone 1a
The switches provided in are the power switch 2, the forward switch 5, and the backward switch 6, but other operation functions (for example, zooming, panning, etc.) related to the image input device 40 may be provided in the remote control integrated microphone 1a. It is possible.

Next, the operation will be described with reference to the drawings.

First, the speaker 31 picks up the remote control integrated microphone 1a and turns on the power switch 2. By this operation, the remote controller 9 becomes conductive. Regarding the microphone unit 10, if the horizontal inclination angle in the longitudinal direction of the remote control integrated microphone 1a is more than 70 degrees, the angle detection sensor 15 conducts the electric current. However, from the viewpoint of human motion, it is rare that the user is in a state of standing up to 70 degrees or more at this point, and the microphone unit 10 is not normally conducted.

Next, the remote control integrated microphone 1a
When the horizontal angle of inclination is 70 degrees or more, the voice input unit 10 becomes conductive by the angle detection sensor 15 and voice can be input. The speaker 31 speaks the contents of the lecture while keeping the remote control integrated microphone 1a in that position.
At that time, the voice of the speaker 31 input from the voice input unit 61 is amplified by the differential amplifier 16 and then modulated by the modulation circuit 17 and sent from the transmitting antenna 19 to a receiver (not shown) connected to the speaker 32. , Is transmitted to the speaker 32 through an amplifier (not shown).

Further, when operating the remote control of the image input device 40, the remote control signal transmission window 4 of the remote control integrated microphone 1a is directed toward the light receiving portion 30 of the image input device 40, for example, the advance switch 5 is pressed to perform the remote control operation. To do. Upon receiving the signal from the advance switch 5, the microcomputer 13 controls the LED driver 12 to cause the LED 62 to emit light. At this time, the horizontal tilt angle of the remote control integrated microphone 1a in the longitudinal direction is smaller than 70 degrees, and the angle detection sensor 15 causes the microphone unit 10 to move.
Is not conducted, the voice input is prohibited.

As described above, the structure of the remote control integrated microphone 1a of this embodiment is such that the direction of the remote control signal (remote control signal) transmitted from the remote control signal transmission window 4 and the piezoelectric conversion section (microphone section 10). However, since the remote control signal transmission direction inclines in the horizontal direction toward the image input device 40 as described above, it is different from the directivity direction of the microphone unit 10.

Further, a remote control integrated microphone 1a
When the remote controller is tilted in the horizontal direction and the remote control is operated, the microphone unit 10 is turned off by the angle detection sensor 15 which is the prohibition means (corresponding to claims 2 and 3) in this case. Howling does not occur even if the speaker 32 is turned toward the speaker 32. Further, the present invention will be described with reference to a second embodiment of the present invention, in which the bothersomeness of the speaker to operate both the remote controller and the microphone is eliminated and the operability is improved.
FIG. 3 is an overall perspective view of a remote control integrated microphone according to a second embodiment of the present invention.

In the second embodiment shown in FIG. 3, the directivity direction of the microphone unit 10 and the direction of the remote control signal transmission window 4 are the same in the structure of the first embodiment, whereas the voice input unit 61 is used. When the speaker is directed toward the mouth of the lecturer 31, the transmission window 4 for the remote control signal is displayed on the light receiving section 30 of the image input device 40.
From the beginning, the structure is such that both directions are different from each other. With such a structure, the voice input unit 6 is operated when the remote control of the image input device 40 is operated.
1 does not face the direction of the speaker 32, so that howling does not occur. The angle detection sensor 15 is also unnecessary for the same reason. The circuit diagram of the remote control integrated microphone 1b in this case is also not particularly shown because the angle detection sensor 15 is simply omitted from the circuit diagram of the first embodiment shown in FIG. In addition, the same components as those in the previous embodiment are designated by the same reference numerals, and duplicate description will be omitted.

Next, the operation will be described. In the case of the second embodiment, with the voice input unit 61 still facing the mouth,
That is, unlike the previous embodiment, the remote-control integrated microphone 1b can be operated by the remote control without tilting in the horizontal direction.

First, when the power switch 2 is turned on, both the remote control section 9 and the microphone section 10 are electrically connected. As it is, voice can be input by directing the voice input unit 61 to the mouth, and the circuit operation in which the voice input is transmitted to the speaker 33 via the differential amplifier 16 and the modulation circuit 17 is performed by the angle detection sensor 15.
2 is the same as the circuit operation shown in FIG. Image input device 4
At the time of remote control operation of 0, if the remote control operation is performed with the voice input section 61 facing the mouth, the remote control signal transmission window 4
Is directed to the light receiving unit 30 of the image input device 40, the remote control signal from the remote control unit 9 is received, and the paper feeding / discharging operation of the image input device 40, the imaging operation of the camera unit 23, the display on the monitor 33, etc. The same operation as in the previous embodiment is performed.

As described above, the remote-control integrated microphone 1b of this embodiment corresponds to claim 5, and the transmitting direction of the remote-control signal and the directing direction of the microphone part are different from each other due to the structure, and the remote-control operation is performed at the time of voice input. The voice input unit 61 is set to the speaker 32 while maintaining a posture that does not change so much.
Howling does not occur because it does not face the direction of.
Also, the operability for the speaker is improved.

Next, a third embodiment of the present invention will be described. FIG. 4 is an overall perspective view of a remote control integrated microphone according to a third embodiment of the present invention. FIG. 5 is a circuit diagram of the third embodiment shown in FIG.

The remote control integrated microphone 1c of the third embodiment corresponds to claim 4. In the first embodiment, the angle detection sensor 15 is used as the prohibition means, whereas the switch 21 is used as the prohibition means. Is used. Therefore, as shown in FIGS. 4 and 5, the power switch is the power switch 20 of the remote control unit 9 and the microphone unit 1.
Power switch 2
1 is composed of a switch that turns off when released.

The power switch 21 is arranged so that the thumb is placed when the remote control integrated microphone 1c is gripped, and the other operation switches 5 and 6 are easily pushed by the thumb. With this arrangement, the remote-control integrated microphone 1c can be operated with a very natural operation.

For example, at the time of voice input, the power supply switch 21 is inevitably pressed by the thumb so that the microphone section 10 is electrically connected, also as the operation of holding the remote control integrated microphone 1c. If the advance switch 5 is pressed during the remote control operation, the thumb moves to the advance switch 5, so that the power switch 21 is inevitably separated (the microphone unit 10 is turned off) and the advance switch 5 is pressed by a human. The shape of the finger is very easy to move.

In the present embodiment, the operation switch of the remote control integrated microphone 1c is arranged in consideration of the case of using the thumb, but the arrangement may be arranged considering the case of using other fingers.

Next, the operation will be described.

First, the speaker 31 presses the power switch 20 of the remote controller 9 to turn it on. Next, the remote control integrated microphone 1c is grasped and the lecture contents are started to be talked. When the remote control integrated microphone 1c is grasped, the power switch 21 is already pushed by the thumb and turned on. Voice input is possible. The circuit operation of FIG. 5 in which the voice input is transmitted to the speaker 32 is similar to that of the previous embodiment.

When the remote control of the image input device 40 is operated,
For example, to push the advance switch 5, the power switch 21
The finger pressing was inevitably separated (microphone part 10
Is OFF), the remote control signal transmission window 4 is displayed on the image input device 40.
And press the advance switch 5 with your finger to
Receives the remote control signal from the remote control unit 9, and the paper feeding / discharging operation, the imaging operation by the camera unit 23, the display operation on the monitor 33, and the like similar to those in the previous embodiment are performed.

As described above, in the remote-control integrated microphone 1c of this embodiment, when the remote control is operated, the continuity of the microphone unit 10 causes the power switch 21 to be smoothly turned off.
Since it is turned off by the operation, even if the voice input section 61 unexpectedly turns toward the speaker 32,
Howling does not occur. Also, the operability for the speaker is improved.

In the present invention, the object to be remotely controlled has been described so far as the image input device 40, but the invention is not limited to this, and image input such as speaker volume or ON / OFF of a plurality of speakers is performed. It goes without saying that anything other than the device can be the target of remote control.
