Abstract
PURPOSE:To make the monitor easy, by projecting a transmitted picture on a screen with magnification by means of a projective lens, in a device monitoring picture transmitted at the same time. CONSTITUTION:A picture picking up an objective with an image pickup lens of a pickup adaptor is transmitted in a transmission line 2 and projected on a screen 8 with a projecting lens 9 of a projector. Thus, since the picture can sufficiently be extended and many persons can view at the same time, even if an object has very high luminance such as monitor of welding of steel plates and monitor in a furnace, the monitor can easily be done.
