PURPOSE:To improve the safety by inverting the closing operation of a window to the opening operation when an article is interposed between the window and a window frame, and inhibiting the reclosing operation of the window until a main power source is reapplied. CONSTITUTION:When the movable contact 41 of a switch 40 is connected with a stationary contact 42, a flip-flop 50a is set, a relay 70 is energized, and a motor M is rotated in a direction for closing a window. When the article is interposed between a window and a window frame in the course of closing the window, a signal is output from a comparator 100, and a flip-flop 50a is reset. Since a detection switch 110 is closed at this time, a flip-flop 50b is set, a relay 80 is energized, and the motor M is rotated in a direction for opening the window. Simultaneously, a flip-flop 150 is set, and the closure of the window is inhibited. |
