Abstract

PURPOSE:To confirm the state of an original at copying, by providing an original stand, and its cover consisting of a transparent plate and a liquid crystal plate provided overlappingly, and an original lighting mechanism illuminating the original on the original stand. CONSTITUTION:An original stand cover 3 is constituted by providing a photo transmission type liquid crystal plate 2 overlappingly on the lower surface opposing to an original start 8, for example, of a transparent plate 1, an operation circuit 6 is operated through the switching of a copy start switch CSW, a lighting mechanism 5 is operated and a voltage signal is applied to the liquid crystal plate 2 to make the plate 2 opaque. In such constitution, since the liquid crystal plate is transparent while the copy start switch CSW is close, the arranging state of an original is visible via an original stand cover 3 to prevent useless copying.
