PURPOSE:To perform communication by many devices at the same time in the optical space transmitter which performs space transmission with other devices by converting transmission data into an optical signal. CONSTITUTION:As light emitting elements, for example, LEDs are arranged with dissimilar directivities on a TX module 7 being a light emitting transmission part. Further, the transmission directivity most suitable for the LED and the required light emitting output are set for each communication party. The set data are stored in a RAM 4. When the communication party is directed, the set data of the opposite party is read out of a RAM 4. The LED is driven according to the data and the communication data is sent as an optical signal to the opposite party. |
