Abstract
Provided is a stick curvature correction device that can determine a curvature of a stick with a simple structure and correct a curvature of a curved stick. The stick curvature correction device includes a curvature detection unit, a center push-up unit, a stick holding unit, and a stick correction unit. The curvature detection unit includes two-end push-up units, and a multi-point sensor unit. The center push-up unit causes a curved stick to axially rotate to be in a mountain bow state, and pushes up a part between a left end and a center of the stick. The stick holding unit holds the right end of the stick, and holds the stick slidably in a direction of the left end of the stick. The stick correction unit applies a force in a direction opposite to a curve direction of the put stick and corrects a curvature of the curved stick.
