  • Patent number: 8336255
    Abstract: An opening and closing apparatus is disclosed that includes an opening and closing body, a force transmitting portion, an elongated sensor body, a support member, and a control section. The opening and closing body is actuated to selectively open and close an opening. The force transmitting portion has a drive portion that generates drive force. The force transmitting portion transmits the drive force from the drive portion to the opening and closing body. The sensor body detects an object between a closing-side end of the opening and closing body and a facing part of the periphery of the opening that faces the closing-side end of the opening. The closing-side end is at an advancing side of the opening and closing body when the opening and closing body is in a closing operation. The support member is fixed either to the closing-side end or the facing part. The support member supports the sensor body.

  • Patent number: 8191311
    Abstract: 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.
