<p><P>PROBLEM TO BE SOLVED: To realize an operation detection device in a form with a small number of components, the operation detection device being capable of accurately obtaining a center location of a force acting on an operation surface even a force acts in a direction different from the direction perpendicular to the operation surface, with an operation mode being enlarged so as to be capable of operating a surface other than the operation surface, and capable of accurately distinguishing the operation to the other surface and the operation to the operation surface. <P>SOLUTION: An operation detection device 1 comprises: an operation body 2 having an operation surface 2a and a convex part 2b; a housing 90 for receiving the operation body 2; three or more flat plate-like strain bodies 3, each having one end at which a connection 3d to the circumference of the operation body 2 is formed and another end at which a fixing part 3c to the housing 90 is formed, and having, between the connection 3d and the fixing part 3c, a displacement transmission surface 3f displaced according to an operation force by a pressing force to the operation surface 2a and the convex part 2b; strain detection sections 4 each fixed on the displacement transmission surface 3f; and an arithmetic logical unit 6 for calculating a location on which the operation force acts in the operation body 2 and the force based on the result of strain detection by each of the strain detection sections 4, the operation surface 2a and all displacement transmission surfaces 3f being nearly on the same plane. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
