OPERATION DEVICE AND DISPLACEMENT ADJUSTMENT METHOD

摘要

An operation device (102) has a resistive-film touch panel (201), a human detector (401), a vibrator (402), and a displacement adjustor (403). The human detector (401) detects human presence near the device (102) by using a human sensor (600). The vibrator (402) vibrates a piezoelectric element (601) previously provided at an edge of the touch panel (201) when human presence is detected near the device (102), to set a predetermined point on the touch panel (201) to which the resulting vibration conducts as a virtual touch point. The displacement adjustor (403) adjusts a displacement by making a measured position value corresponding to the virtual touch point equal to a previously set reference position value corresponding to the touch point.
