<p><P>PROBLEM TO BE SOLVED: To do away with risk of false detection in a keyboard device wherein an input operation face positioned on the topmost face is a flat face. <P>SOLUTION: A keyboard operation part 10 is floating-supported to a lower case 1 by three or more points by a floating mechanism 14, so that the keyboard operation part 10 is stably held by the lower case 1 with a prescribed freedom degree to the lower case 1. Displacement of the keyboard operation part 10 to the lower case 1 is permitted, so that a load applied to the keyboard operation part 10 is conveyed to a load sensor 22 together with the displacement of the keyboard operation part 10 to the lower case 1, and the load applied to the keyboard operation part 10 can be obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
