Patent number: 9457984Abstract: While a winding member is making one rotation, an optical fiber is once skewed relative to the circumferential direction and further shifted by a desired length in the width direction of a circumferential surface. In this state, the winding member winds up the optical fiber. This operation is performed in the same direction every rotation when the winding member rotates (N?1) times. Next, in the N-th rotation of the winding member, a guide member performs the guide to the optical fiber to skew reversely to the direction of shifting in the (N?1) rotations of the winding member.Type: GrantFiled: January 28, 2016Date of Patent: October 4, 2016Assignee: OLYMPUS CORPORATIONInventor: Hiroki Takagi
