Abstract
A wireless keyboard system includes a wireless keyboard and a receiver unit. The wireless keyboard includes a controller and a transmitter. The controller detects the status of a standard key and nontext keys and generates a status information representing whether the nontext key is pressed or released and a key data representing which standard key is pressed and which nontext key is pressed. The transmitter transmits the key data together with the status information. The receiver unit generates a key code on the basis of the key data with reference to the status information.
