A thermal transfer color copying machine reads out an image signal of a document by scanning it, heats a thermal head, and transfers images having respective colors to a copying paper sheet from an ink ribbon to obtain a color copy. The copying machine has a pattern display unit for graphically and schematically representing a paper feed cassette, a copying paper sheet, a convey path of the copying paper sheet, a platen roller, a thermal head, an ink ribbon, a discharging path of a color copied paper sheet and the like, thereby representing the actual operation of the copying machine, i.e., a position of the copying paper sheet, which thermally transferred colors have been transferred, thermally transferring colors are in the process of being transferred, and which colors are to be transferred to the copying sheet.
