ABSTRACT:
A keyboard for lowering the power consumption for key code transmission and enhancing the reliability in code transmission. When key codes corresponding to an operated key in the laid out keys are transmitted to a signal processing unit, a status code indicating whether a function key (Shift, Control or Alt key) has been operated is also transmitted at the same time, transmitting no key-on repeat code that is obtained when one key is operated continuously as with a conventional keyboard.
