ABSTRACT:
An original-holding cover for use in association with an image formation device comprising an upper unit and a lower unit, the upper unit being rotatably mounted on the lower unit so as to be opened and closed, which comprises a base part rotatably connected to an original platen of the upper unit and an original-holding part which is rotatably connected to the base part. When a thick original is duplicated, the entire surface of the original can be uniformly pressed irrespective of the thickness of the original with the original holding part held in a horizontal position by rotating both the base part and the original-holding part. Furthermore, the base part is removable from the original platen and there is provided a stopper means for preventing disconnection of the base part from the original platen due to the impact of opening the upper unit when dealing with a jam or other trouble.
