Claims

[Claims for Utility Model Registration] A swing lever 2 is pivotably supported around a pivot shaft 13 regardless of the direction of rotation of the shaft 13;
An idler 3 is mounted on the lever 2 in contact with the rotation shaft 13.
The idler 3 is brought into contact with either one of the take-up reel stand 8 and the supply reel stand 7 placed on both sides of the swing lever 2 by switching the rotational direction of the rotation shaft 13. In the idler mechanism for rotationally driving the swinging lever 2, an idler 3 is provided at one end of the swinging lever 2 around the swinging center A of the lever, and a weight 41 is arranged at the other end so as to be able to approach and move away from the swinging center. When the weight 41 is at the maximum distance from the swing center A of the swing lever 2, the rotation moment on the idler side about the swing center of the swing lever 2 acts in the opposite direction to the rotation moment. When the weight 41 approaches the swing center A of the movable lever 2 at its maximum, the rotation moments acting on the idler side and the weight side in opposite directions have a relationship opposite to that described above. An idler device for driving a reel stand, which is characterized by: The weight 41 is attached to a weight lever 4 that is pivotally supported on the swing lever 2.
The idler device for driving a reel stand according to claim 1, wherein two stoppers 6, 61 are provided for regulating the rotation range of the weight lever 4. The idler device for driving a reel stand according to claim 1, wherein the weight 41 is slidably fitted into a guide member 43 provided on the swing lever 2.
