Color image reproducing apparatus with sheet feeding device for recirculating a sheet on which dots of different colors are sequentially recorded

摘要

A trichromatic photosensor scans an image to be reproduced repeatedly to generate, for each elementary area scanned, signals indicative of the chromatic characteristics of this elementary area. The photosensor is connected to a trichromatic printer controlled by the signals produced by the photosensor for printing corresponding colored dots on the paper. During successive scanning operations, the photosensor is moved relative to the color image and the printer is moved relative to the paper. These relative movements are coordinated with each other so that the photosensor and the printer act simultaneously on corresponding regions of the color image and of the paper. In one embodiment the printer is stationary and is capable of printing in parallel the dots of one line. The paper circulates along a closed path to be sequentially printed according to the various color components. In another embodiment the printer is of the serial type. The printing carriage mounts also the photosensor and moves transversely the printer and the photosensor to repeatedly scan the printing line.
