Abstract
A non-contact direction changer includes: a guide groove that guides an optical fiber and changes a direction of advancement of the optical fiber from a first direction to a second direction; a bottom ejection opening at a bottom of the guide groove; and one or more side ejection openings on at least one of opposite side surfaces of the guide groove. A fluid is ejected into the guide groove through the bottom ejection opening. A fluid is ejected into the guide groove through the one or more side ejection openings.
Claims14
A non-contact direction changer comprising:
- a guide groove that guides an optical fiber and changes a direction of advancement of the optical fiber from a first direction to a second direction;
- a bottom ejection opening, provided at a bottom of the guide groove, through which fluid is ejected into the guide groove to cause the optical fiber to float;
- and
- one or more side ejection openings, provided on at least one of opposite side surfaces of the guide groove, through which fluid is ejected into the guide groove, wherein
- each of the opposite side surfaces includes an inclined portion that is inclined such that an opening of the guide groove is continuously larger as the opening is farther from the bottom of the guide groove, and
- the one or more side ejection openings are provided on the inclined portion.
