Abstract
Magnetographic copier having a movable carriage on which the process stations for recording, developing, transferring and cleaning are mounted. A ribbon of magnetic tape is threaded through the process stations and is held stationary during the image processing, so that the movement of the carriage causes the tape to pass all of the process stations. A CCD array scans segments of a fixed original document and then returns to a start of scan position where it is stepped. The carriage and CCD array are concurrently stepped a distance substantially equal to width of a segment prior to the next scan. The CCD array and carriage are connected by cable and move concurrently. The elements of the CCD array are connected in a one-to-one manner with elements of a magnetic recording head at the recording station. Start of scan is initiated by sensing accurately placed holes in the magnetic tape and width of scan is controlled by marks on a code strip which are detected by the CCD array elements to adjust the number of elements enabled.
