Abstract:
An opening-and-closing member control device having a contact for opening and closing an energizing line to a motor for driving an opening-and-closing member in a vehicle, to have two relays for operating the motor in a direction toward opening or closing the opening-and-closing member during operation, a switch to be operated by a manipulation of a vehicular user, and a control circuit for driving any of the relays depending upon an operation state of the switch, the opening-and-closing member control device wherein,the switch comprises: a first common terminal connected to a ground; a closing signal terminal to be conducted to the first common terminal by an operation instructing for closing the opening-and-closing member and turned from a plus potential into a ground potential; an opening signal terminal to be conducted to the first common terminal by an operation instructing for opening the opening-and-closing member and turned from a plus potential into the ground potential; an auto-closing signal terminal to be conducted to the first common terminal by an operation instructing for auto-full-closing operation of the opening-and-closing member and turned from a plus potential into the ground potential; and an auto-opening signal terminal to be conducted to the first common terminal by an operation instructing for auto-full-opening operation of the opening-and-closing member and turned from a plus potential into the ground potential; the control circuit has functions of: driving a closing-sided relay when the closing signal terminal is at the ground potential, and driving an opening-sided relay when the opening signal terminal is at the ground potential; continuously driving the closing-sided relay until the opening-and-closing member is detected as in a full closed state or a foreign-matter-catching state when the closing signal terminal and the auto closing signal terminal become the ground potential; and continuously driving the open-sided relay until the opening-and-closing member is detected as in a full opened state when the opening signal terminal and the auto opening signal terminal become the ground potential; wherein arrangement is made such that the closing signal terminal and the first common terminal as well as the opening signal terminal and the first common terminal are not in adjacent relationships.
