PURPOSE:To easily use the light space transmission between information processors like personal computers to constitute a system. CONSTITUTION:Information processors 10 and 11 like personal computers, word processors, or printers are provided with transmission/reception parts 20 and 21, which communicate with each other by light, and can be half rotated rightward and leftward by hands as shown by arrows 41 and have light transmission/ reception zones 33 easily directed to desired directions and use the transmission/ reception light 31 to transmit and receive required data. Consequently, not only one-to-one communication but also one-to-plural communication between information processors is facilitated to attain the purpose because communication with the other party is easily and surely realized. |
