  • Patent number: 8746671
    Abstract: A sheet conveying system includes a sheet inserting apparatus that inserts a second recording medium between first recording media conveyed by a sheet conveying apparatus, and transmits a first time at which second recording media can be successively received hypothetically, and a second time indicating a difference between a conveying time from an accumulating unit of a second recording medium to a merging point at which a second recording medium is inserted and a conveying time from a sheet receiving surface of the sheet inserting apparatus to the merging point. The sheet conveying apparatus sets longer one of the received first time and second time as an insertion interval; and conveys first recording media such that an interval extended by an added value obtained by adding a conveying time corresponding to a length of second recording medium to the insertion interval is provided between the first recording media.
