いた。The light propagates to the receiving device of the other party by reflection of light from walls, floors, etc. However, when communicating from a closed space completely covered on all sides by ceilings, walls, etc., to another closed space, light, which is the transmission medium, does not propagate from one closed space to another. It has the disadvantage of not being able to communicate. Conventionally, optical fibers have been used as this measuring means. However, devices using optical fibers have the disadvantage that the transmitter/receiver is fixed in position and cannot be carried around at all times.

。The signal transmitted by optical transmission is formed of a marker signal and an information signal, and the marker signal is used as the information signal, and the information signal is a control signal or audio signal consisting of an address signal, command signal, etc. It is used to transmit information from one space to another closed space, and it is PCM modulated, converted to optical output, and transmitted through air propagation. input and demodulate the information signal. The information signal is processed by the CPU as a numerical value. As described above, the light such as infrared rays emitted from the closed space is received by the light receiving element 11), and the light is transmitted from the light emitting element (2) to another closed space via the amplified light emitting drive circuit (3). It can be fired and communicated with another closed nitrogen 1111 by optical transmission.
