摘要
In the optical wireless communication, in the case where the optical signal transmission quality changes due to environmental factors and usage and aging, etc., such as surface and propagation space of the optical lens to propagate also, to maintain the communication quality in a predetermined quality to provide an optical wireless system. system for transmitting the electronic component mounting apparatus 10 various information relating to the mounting operation of the substrate of electronic components, converts the optical signal into an electrical signal RD by light receiving and emitting unit 3A. Level detector 3B has detected the voltage level of the converted electrical signal RD, in response to the voltage level drops, it performs preset parameters for switching the error correcting method in the predetermined error correction method. Then, switching to an error correction method that is pre-set in response to further detect a drop voltage level.
