摘要： A color scanner having two lines of CCD. One of the CCD line is used for scanning green image of a document, and another CCD line is used for scanning red and blue images of the document. In the CCD line for red and blue image scanning, red and blue filters are located alternatively on the pixel sensors in a lined shape. In order to obtain a pixel density corresponding to the red image and blue image as same as that to the green image, each of red and blue image signals is processed from two image signals. The color scanner is provided with a memory to store red and blue image signals so that those signals are processed with next-obtained red and blue image signals. The color scanner also includes a shift register to delay green image signals so that all of red, blue, and green image signals are carried out to a processor simultaneously.

摘要： An apparatus for forming images on at least one surface of a sheet includes a reader for reading image information on documents, a memory for storing image signals output by the reader, and an image forming unit for selectively forming one of: (i) two page toner images corresponding to the image signals of two pages of the documents separately on two image carrying members, and (ii) a single toner image on one of the two image carrying members. A jam detector detects a jammed sheet, and a delivery detector detects delivery of a copied sheet to outside the apparatus. Image signals are eliminated from memory in accordance with a progression of image formation. If the jam detector detects the occurrence of the jammed sheet, a control unit prohibits the memory from eliminating the image signals until the delivery detector detects a next sheet delivered from the apparatus, so that the selected image expected to be formed by the image forming unit on the jammed sheet may be properly formed on a following sheet based on the image signals retained in the memory. A selector is provided for selecting one of a both-surface copy mode and a single-surface copy mode, wherein the control unit controls the memory to store the image signals corresponding to two pages of the documents when the both-surface copy mode is selected and to store the image signals corresponding to the single page of the documents when the single-surface copy mode is selected.
