PURPOSE:To prevent continued inclusion of eventually pinched foreign matter which arises on the way of a window glass moving in the direction of closing. CONSTITUTION:When any foreign matter lies in the direction in which a window glass rises, a latch circuit 92 is set in conformity to the output signal from a motor over-load current sensing circuit 90 to sense over-current in a motor 12 and the output signal from a full close sensor 96 which senses that the window glass is not fully closed, and the transistor 26 is turned off while another 28 is turned on, and a relay 16 is actuated to rotate the motor 12 reversely, and the window glass is sunk. If at this time, the push on a manual switch at the assistant seat or a switch for raising 51 at the driver seat is continued, a latch circuit 54 is not reset, and the motor 12 continues reversing until these switches 50, 51 are both turned off. If the window glass is not fully closed and approx. 10sec after either switch is put on, the transistor 26 is turned off while the other 28 turned on in conformity to the signal given by a timer circuit 74, and the window glass is sunk. |
