Abstract

PURPOSE:To improve reliability for an changeover of an optical path and to obtain long life by making a transparent body having a pair of parallel planes rotatable. CONSTITUTION:When parallel planes 12a, 12b of a transparent body 12 is perpendicular to an optical axis of focusing type lenses 9, 10 and 11 (the solid line), light from the focusing type lens 9 is, going straight on, led to on optical fiber through the focusing type lens 10. When the transparent body 12 is then inclined with a rotation to the optical axis (two dot chain line) light from the focusing type lens 9 is refracted at parallel planes 12a, 12b, passes through a path indicated by a hypothetical line 31, and introduced into the optical fiber via the focusing lens 11. An operation for a rotation of the transparent body 12 can be done by using a permanent magnet and by utilizing a magnetic adsrobing action.
