PURPOSE: To provide a superior optical wireless communication equipment in which the number of bits to be communicated is prevented from being regulated due to erroneous recognition when the bit is omitted or the dispersion of clock accuracy of a receiver itself as, for example, the communication method of a signal in an optical wireless keyboard switch.
CONSTITUTION: This equipment is comprised so that the receiver can take synchronism at a timing when data is inverted by an inverted data bit 3 by transmitting two bits of a data bit 2 and the inverted data bit 3 and such effect that the number of transmission bits regulated due to the dispersion of the clock accuracy of the receiver can be increased can be expected. Also, such effect can be expected that the erroneous recognition can be prevented from occurring even when the bit is omitted due to the cutoff of the communication route of light by an obstruction such as a person, etc.
