Abstract:
A keyboard comprising:a key code generating section for generating a key code corresponding to an operated key of a plurality of laid-out keys;a key code transmitting section for transmitting said key code to a host signal processing unit;wherein said key code transmitting section, if more than one key of said plurality of laid-out keys are sequentially operated consecutively, transmits collectively a plurality of key codes corresponding to the operated keys to said host signal processing unit; andkey codes corresponding to laid-out keys which are sequentially operated consecutively are temporarily stored in a memory, and a plurality of key codes are collectively read from the memory over a predetermined time interval, and are collectively and intermittently transmitted to a host signal processing unit;when said plurality of key codes are transmitted to said host signal processing unit, the same data shared by said plurality of key codes is collectively transmitted; andwherein, if more than one key are sequentially operated consecutively, said key code transmitting section transmits immediately only a key code corresponding to a first-operated key of the operated keys to said host signal processing unit and transmits collectively the codes corresponding to the rest of the operated keys to said host signal processing unit.
