PROBLEM TO BE SOLVED: To provide a device which can reverse a motor to drive the glass only when it is operated in the window glass closing direction by a pressure sensitive sensor and the simple circuit constitution. SOLUTION: A pressure sensitive sensor 4 is installed on an opposed surface in the direction for closing window glass, and when a thing or the like is sandwiched between the window glass and a window frame, the pressure sensitive sensor 4 is turned on by sensing pressure. A first MosFET 19 is turned on in a reversing circuit 12 by ON of the pressure sensitive sensor 4, and a motor 11 to drive the window glass is reversely operated by operating relays 9 and 10, and the window glass is operated so as to be opened. At that time, since a second MosFET 21 of a self-hold circuit 13 is turned on, the window glass does not again perform closing operation as long as a movable terminal 7c of a closing operation switch is separated from a contact point 7b. |
