<P>PROBLEM TO BE SOLVED: To provide a keyboard, provided with a mode switching function, including at least one key, a pressure detecting circuit, a light-emitting module, a mode switching program, and a control unit. <P>SOLUTION: The mode switching program enters a keyboard 30 into a pressure-sensitive light-emitting mode by activating a pressure detecting circuit 3041 and a light-emitting module 307. The pressure detecting circuit 3041 generates a depression strength voltage by detecting the magnitude of each of depression keys 301. A control unit 306 controls a light-emitting module to emit a first beam B1 or a second beam on the basis of the depression strength voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
