WIRELESS INPUT SYSTEM

摘要

PROBLEM TO BE SOLVED: To extend the life or a battery by reducing the number of bytes constituting one input information to perform the communication at the time of communication of one input information consisting of plural bytes. SOLUTION: One input information transmitted from a wireless input device 1 to a wireless reception equipment 2 and is transmitted to a main body 3 us fundamentally constituted with a format of three bytes; and at the time of transmission from the wirelsss input device 1 to the wireless reception equipment 2, the first byte consists of on/off information of right and left switches of a pointing device, information related to the X/Y-direction of data, and information in bits 6 and 7 indicating the number of bytes of transmission of one input information. Second and third bytes indicate data 0 to 255 in the X/Y-direction. At the time of transmission from the wireless reception equipment 2 to the main body 3, three bytes except contents of bits 6 and 7 of the first byte out of contents of one input information transmitted from the wireless input device 1 are transmitted.
