<p><P>PROBLEM TO BE SOLVED: To provide an operation device which allows degradation of a sensor to be suppressed. <P>SOLUTION: When a user touches an operation surface 4c of a touch panel 4, force is applied to the center side of the touch panel 4 inside of a support shaft 7. Force acts on a corner part 4a of the touch panel 4 in a direction (upward direction in Figure 1) opposite to user's depressing direction because of action of the support shaft 7. Then, an initial load preliminarily applied to a pressure sensor 6 is reduced, and the pressure sensor 6 detects the amount of reduction in load. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
