Title:
静電容量センサ
Document Type and Number:
Japanese Patent JP6802855
Kind Code:
B2
Abstract:
A capacitive sensor has first electrodes 111, 112, 113, 114, 115, 116, 117, and 118, a second electrode 12, and a third electrode 13, which are disposed at places where a manipulating body 2 that is part of a human body such as a finger is detected. The capacitive sensor has a capacitance detecting means 3 and a deciding means 4. The number of manipulating bodies and directions (positions) are identified according to the capacitances of the first electrodes 111, 112, 113, 114, 115, 116, 117, and 118, second electrode 12, and third electrode 13.
