Abstract
A medium transporting mechanism is used in a color image forming apparatus and a color image reading apparatus. The medium transporting mechanism includes a medium holding section and a rotary transporting section. The medium holding section holds a print-medium by clamping the leading end of the print-medium. The rotary transporting section supports the medium holding section thereon and rotates so that the medium holding section travels around a platen in such a manner that the print-medium slides on at least a part of the platen and the medium holding section travels in a loop-like path which is shorter than a maximum dimension of the print-medium in a direction of travel of the print-medium. A color image recording section is located to oppose the platen so that a print-medium passes between the color image recording section and the platen. The color image recording section prints images of yellow, magenta, cyan in sequence and in register on the print-medium. A monochrome image recording section such as an electrophotographic printer may be provided in addition to the color image recording apparatus. The electrophotographic printer prints a black image only. When printing a color image, the electrophotographic printer prints a black image at a high speed and the color image recording section prints images of other colors such as yellow, magenta, and cyan at a slow speed, thereby speeding up overall printing speed in color printing operation.
