Proximity sensor and rotational operation detecting device |
摘要 |
A proximity sensor for determining an approaching direction of an object is provided. Relative detection sensitivity is established in a first detection unit and a second detection unit such that a detection level of the first detection unit is greater than a detection level of the second detection unit when the object approaches from a first electrode in a direction of arranging the first electrode and a second electrode, and that the detection level of the second detection unit is greater than the first detection unit when the object approaches from a direction perpendicular to the direction of arranging the first electrode and the second electrode. A proximity position determining section is adapted to determine the approaching direction of the object based on the detection level of the first detection unit and the detection level of the second detection unit. |
