摘要： An opening and closing apparatus having an opening and closing body, a drive portion, a control portion, and a detecting device is disclosed. The detecting device has a sensor portion for detecting the capacitance between the sensor portion and an object that is in the proximity of the sensor portion or is contacting the sensor portion. The detecting device detects that the object is in the proximity of the sensor portion or is contacting the sensor portion based on the capacitance detected by the sensor portion. If the detecting device detects contact of the object with the sensor portion when the opening and closing body is not being moved, the control portion controls the drive portion to start opening the opening and closing body. If the detecting device detects that the object is in the proximity of the sensor portion when the opening and closing body is being closed, the control portion controls the drive portion to stop or reverse the movement of the opening and closing body.
