CAPACITIVE MOTION DETECTION DEVICE AND INPUT DEVICE USING THE SAME
First Claim
1. A capacitive motion detection device comprising:
- two or more detection electrode/drive electrode pairs in each of which a capacitance is formed between a detection electrode and a drive electrode;
motion detecting means for performing noncontact motion detection of an object to be detected in an area to be operated in two or more axis directions from a variation in a capacitance obtained in each of the detection electrode/drive electrode pairs; and
switching means for switching a mode to a mode of the motion detection.

Abstract
When the mode is switched to a motion detection mode, using a changeover switch, the mode is switched to the motion detection mode by pressing the changeover switch. In this mode, motion detection is performed by moving a hand in an area to be operated. When the mode is switched from the motion detection mode to a normal mode, the hand is moved away from the area to be operated, or the changeover switch is again pressed. Moreover, when the hand is distant from a capacitive sensor, it is determined that a motion input operation is being performed. When the hand is close to the capacitive sensor, it is determined that no motion input operation is being performed, and thus the motion detection mode is changed.
