An apparatus for making a color proof. An original loading portion having a loading opening provided for loading the original is disposed side by side at an exposure portion so that a carriage may be substantially horizontally moved between the exposure position of the exposure portion and the copy exchange position of corresponding to the loading opening. When the original is exchanged and recharged, the loading opening is open by a lid member and when the carriage is positioned to the copy exchange position, the original is placed. Since the exposure portion and the like are not disposed upwardly of the original loading portion, the exposure unit and the like are not mounted with the result that the lid member can be made compact and lightweight while exchange of the original can be eased. In addition, the carriage is not withdrawn into the working space allowed for the operators.
