Document Type and Number:
Japanese Patent JP2018194010
Kind Code:
A
Abstract:
To provide a width adjustment mechanism, a width adjustment power transmission mechanism, a winding mechanism having the width adjustment power transmission mechanism, and a feed mechanism having the width adjustment power transmission mechanism by simple constitutions.SOLUTION: A width adjustment mechanism of a rotating shaft comprises: a trapezoidal screw shaft 1 for converting a rotational motion and a linear motion; a gear 2 screwed at an inside diameter; a gear 3 not screwed at the inside diameter; and a cylindrically-screwed pivot 4. The gear 3 not screwed at the inside diameter comprises a connecting part 5 which separates from and joins to the pivot 4, is constituted so that the connecting part 5 separates from and joins to the pivot 4, and in order to change a width position of the trapezoidal screw shaft 1 which is regulated by a position of the gear 2, the pivot 4 can change a positional relationship between the gear 2 and itself by rotating the gear 3. Also, the pivot 4 can adjust the width position of the trapezoidal screw shaft 1 which is regulated by the position of the gear 2 by rotating the gear 2 in a state that the pivot 4 separates from the gear 3 and the gear 2, and can rotate the trapezoidal screw shaft 1 without changing the width position by rotating the gear 3 in a state that the pivot 4 tightly adheres to the gear 2.SELECTED DRAWING: Figure 1
