Abstract
An open-close member control apparatus has a function to release a foreign matter pinched to an open-close member. The open-close member is either (i) driven only while a manipulation switch is manipulated or (ii) driven continuously once the manipulation switch is manipulated to a specified position regardless of whether the manipulation is then released. When trapping of a foreign matter is detected under an open movement of the open-close member to an open direction based on an open command signal from the manipulation switch, an electric power supply to a motor is restricted to stop a progress of the trapping. When receiving a close command signal from the manipulation switch after restricting the electric power supply, the electric power is supplied to the motor to drive the open-close member to a close direction under a restricted state of a predetermined operation.
