ABSTRACT:
In an electrophotographic copying apparatus, a cover and document keep device comprises a rigid cover member for securely holding original documents during copying and for effectively shielding the user from exposure to ultraviolet or visible radiation. A support member incorporating a plurality of positioning rods is vertically slidingly engaged within holes formed in the copying apparatus housing. An L-shaped frame is hinged by a first hinging means to the vertically movable support member, and carries the rigid cover by an additional second hinging means. Fastening means are provided to allow only one of the hinging means to be operated at one time, thereby allowing the rigid cover member to be pivoted about either axis defined by the hinging means. Accommodation of various original document thicknesses is provided by vertical sliding movement of the support member.
