Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a communication device in an area where a worker needs to wear a protective mask, such as a radiation control area and a dust generation area.

[0002]

[Prior Art]

 It is necessary to wear a protective mask when working in areas where radioactive particles and other gaseous or powdery harmful substances are suspended. However, when the mask is worn, the voice remains muffled inside the mask, making it difficult to talk outside. In order to make up for this drawback, methods such as attaching a diaphragm near the exhaust hole of the mask, installing a microphone inside the mask and a small speaker with a built-in battery outside to talk with each other have been used. There is a difficulty in the clarity of.

There is also a method of making a call using a microphone mounted inside the mask and a wireless transmitter / receiver housed in a pocket of clothes, but this also requires an antenna, which makes the device large. In particular, recently, a large number of various electric control precision devices have been used, and there are drawbacks such that they may cause radio wave interference and, conversely, noise may easily enter due to radio waves generated by these devices.

[0004]

[Problems to be solved by the device]

 The present invention eliminates the above-mentioned drawbacks, is easy to listen to, is small and lightweight, is easy to carry, is not affected by noise from other devices, and does not generate noise that affects other devices. A mask communication device is provided.

[0005]

[Means for Solving the Problems]

 A microphone built inside the protective mask 1 or 1 ', an outer headset 5 for taking out the signal of this microphone in a hermetically sealed manner via a wire 6, and an optical talk transmitting / receiving device connected via the headset 5 and the wire 6'. 7, an optical fiber cord 8 connected to another optical talk receiving / transmitting device 7'that connects the optical talk receiving / transmitting device 7, and a headset 5'connected to another optical talk receiving / transmitting device 7'by wiring 6 ". did.

【Example】

 The present invention includes a microphone inside a protective mask, wiring for taking out the signal of the microphone to an outside headset in an airtight state, a headset, an optical talk receiver / transmitter connected to this headset, and another optical talk receiver / transmitter from this headset. It is composed of an optical fiber connected to the optical talk receiver / transmitter and another headset connected to another optical talk receiver / transmitter.

The present invention will now be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. In the figure, reference numeral 1 is a rubber-made full-face protective body whose edge portion adheres to the face when worn. It is a mask. The protective mask 1 has a transparent window 2 in front of it and intake / exhaust ports 3 at the cheeks on both sides, which are provided with removable filters. In addition, a tubular pedestal with a threaded portion on the outer periphery is attached to the palate portion of the protective mask 1, and a lid 4 in which a microphone is airtightly embedded is screwed to this pedestal by airtight packing. ing. The wiring 6 is connected from the microphone to the headset 5, and is further connected to the optical talk receiving / transmitting device 7 through the wiring 6 '.

The optical talk receiver / transmitter 7 has a built-in battery, and as shown in FIG. 2, a switch 9, a volume control knob 10, a talk button 11, a call key 12, a voice reaction operation switch 13 and the other light. The other optical talk receiving / transmitting device 7'includes an optical fiber cord 8 connected to the talk receiving / transmitting device 7 '. Five are connected.

As the protective mask, a full-face mask or a half-face mask is appropriately selected and used according to the state of the work area, and outside the area, not only a headset but also an interphone or a microphone / speaker system may be used.

(Usage) (1) Power source and partner waiting transmission switch ON ... The optical talk reception / transmission device 7 is powered on and transmission / reception is possible. The buzzer sounds while receiving a call waiting (TONE) signal or a call (CALL) signal. Answer the call or use a headset. TONE (waiting signal for other party) ・ ・ ・ Used when the power is ON and communication with the other party is not possible. In the TONE state, if a buzzer signal is transmitted intermittently and the other party receives our signal and responds with a call signal, our buzzer will call, so the switch can be returned to the ON state to enable communication. OFF: The power of the optical talk receiver / transmitter is turned off.

【effect】

 Take out the microphone built in the protective mask and the signal of this microphone to the outside headset in an airtight state, connect this headset to the optical talk receiver / transmitter, and connect it to another optical talk receiver / transmitter with an optical fiber cord. In addition, a telephone set was constructed by connecting this optical talk receiver / receiver with a headset.

[0012] According to this, in work in an area where the worker needs to wear a protective mask, such as a radiation control area and a dust generation area, information can be reliably exchanged and a safe work can be secured.
