PURPOSE:To use a single set of camera and monitor television simultaneously supervising two or more safeties by dividing an input part of an optical fiber group while unifying an output part and providing the monitor television and the camera appearing in this output part. CONSTITUTION:Two or more objects A, B are placed in each front of two or more lenses 1, 2 and imaged in two or more optical fiber groups 3a, 3b in a condition inverting each image respectively by each lens 1, 2. An optical fiber transmission path 3 is bundled so as to unify an output side for a two- divided input side. While light, input to each optical fiber group 3a, 3b, forms an image in a camera 5 in its picture taking part by a lens 4 in the output side. Further the camera 5 is reversely set up in its vertical position, thus a monitor television 6 displays each object in a condition that it is arranged normally rising. Thus, a single set of the camera 5 and the monitor television 6 is used simultaneously performing two or more safety supervisions. |
