Claims (1)

[Claims for Utility Model Registration] 1. By rotating a winding body such as a drum in both forward and reverse directions by driving a motor, a member to be wound, such as a wire, which has been pulled in the feeding direction, resists the tension in the feeding direction. In the winding drive device, the winding body is wound by a main body that rotates concentrically with the winding body, and a main body that rotates eccentrically from the center of rotation of the main body. an actuating body supported by a swing shaft at a position, the actuating body approaches the center of rotation of the main body and abuts the main body, and the actuating body approaches the center of rotation of the main body and contacts the main body; The winding body is configured to be able to swing between a contact state and a separated state in which the winding body protrudes outward from the maximum circle drawn by rotation of the winding body, and the winding body is positioned at a position spaced apart from the swing axis of the operating body. The winding ends of the members are connected so that the winding body is held in the abutting state by winding the winding member around the outer periphery of the winding body, and the winding body is held at a position near the winding body. , a switch that corresponds to the outer circumferential surface of the winding body in the abutting state and that is actuated by pressure from the rotation center side of the winding body to stop driving the motor in the feeding direction; A motor stop device in a take-up drive device, characterized in that it is provided with a motor stop device. 2. By rotating a winding body such as a drum in the forward and reverse directions by driving a motor, a member to be wound such as a wire that is pulled in the feeding direction is wound up against the tension in the feeding direction, or the said feeding In the winding drive device, the winding drive device is configured to unwind according to a tension in a direction, and the winding body includes a main body that rotates integrally with the winding body, and a swing shaft supported at a position eccentric from the center of rotation of the main body. A rotating body consisting of an actuating body is attached, and the actuating body approaches the rotation center of the main body and contacts the main body, and the contact state is separated from the rotation center of the main body. The winding member is configured to be able to swing between a spaced state in which it protrudes outward from the maximum circle drawn by the rotation of the rotating body, and the winding member is moved to a position spaced apart from the swing axis of the operating body. the rotating body is held in the abutting state by winding the wound member around the outer periphery of the winding body; The winding device is characterized in that a switch is provided which corresponds to the outer peripheral surface of the rotary body at a distance and is actuated by pressure from the rotation center side of the rotary body to stop driving the motor in the feeding direction. A motor stop device in a drive unit.
