Abstract
PURPOSE:To generate scanning codes more than the number of actual keys and to promote the extendability of a keyboard on the system where a hardware is specified by preparing separate scanning codes at the state in which an extending key is inputted and at the state in which the extending key is not inputted even when the same ordinary key is inputted. CONSTITUTION:The device has the keyboard provided with plural ordinary keys and extending keys, and a control part to generate the prescribed scanning code when the ordinary key is inputted and to generate another scanning code when the ordinary key is inputted at the state in which the extending key is inputted. Namely, a keyboard device 1 is connected to a CPU 7 and the CPU 7 generates a corresponding scanning code when an ordinary key 3a on a keyboard 2 is inputted. When, at the state in which an extending key 5 is inputted, an ordinary key 3a is inputted, another scanning code is generated. Thus, the scanning codes more than the number of the really existing ordinary keys can be prepared.
