摘要： PURPOSE:To perform various kinds of optical inspection mechanically by moving a conveying device reciprocally, conveying plural holders, mounted on a palette stage, to a simple butting device in order, and connecting terminals of both optical fibers by butting. CONSTITUTION:The conveying device 30 grips the holders 2 mounted on the palette stage 20 in order and conveys the holders 2 reciprocally between the simple butting device 10 and palette state 20. Then a butting stage moves forward with the energizing force of a flat spiral spring to make a butt connection between respective coated fibers on a side to be measured and coated optical fibers on a measurement side. Thus, while the optical fibers on the measurement side and optical fibers on the side to be measured are butted and connected automatically and easily, transmission loss, etc., is measured optically. Consequently, the butt connecting operation for the optical fibers and various kinds of optical inspection are performed continuously and automatically.
