Operation device and displacement adjustment method

摘要

An operation device has a resistive-film touch panel, a human detector, a vibrator, and a displacement adjustor. The human detector detects human presence near the device by using a human sensor. The vibrator vibrates a piezoelectric element previously provided at an edge of the touch panel when human presence is detected near the device, to set a predetermined point on the touch panel to which the resulting vibration conducts as a virtual touch point. The displacement adjustor 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.

1. An operation device including a touch panel of a resistive-film type, comprising:
a human sensor having a detection area near the touch panel; a piezoelectric element provided at an edge of the touch panel to vibrate; and a control circuit connected to the human sensor and the piezoelectric element, Wherein: the control circuit makes the piezoelectric element vibrate, when the human sensor detects a human to be present near the device, in order to set a predetermined point on the touch panel to which resulting vibration conducts as a virtual touch point, and the control circuit 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.
