<p><P>PROBLEM TO BE SOLVED: To provide an operation input apparatus capable of preventing the continuation of an unintended operation input and the application of an excessive load to an operation panel faced reversely to a gravity direction. <P>SOLUTION: The operation input apparatus provided with an operation panel 12a in which a touch operation surface 12a1 is arranged on the upper surface detects a depression energizing force level to the touch operation surface 12a1 due to touch input by a pressure sensor 20, and when the depression energizing force level exceeds a prescribed threshold level and when the input continuation time of the touch input to the touch operation surface 12 counted by a control circuit 18 exceeds threshold time, recognizes the state as an abnormal input state and outputs an alarm by a buzzer 30. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
