Abstract

PURPOSE:To deal with the diversification of transmitted information by detecting and indicating the amount of an enclosed paper for each envelope from which an encoded mark assigned to the enclosed paper is read and grouping enclosed papers and enclosing grouped papers in envelopes in the process of enclosing the paper and sealing the envelope. CONSTITUTION:An encoded mark label 99 for grouping is printed in advance on a continuous paper for forming each enclosed paper. The encoded mark label 99 is read by a mark sensor 8, and the grouping of enclosed papers, selection/enclosing of additional enclosed papers and delivery of plain enclosed paper are instructed. A grouping mechanism 25 has a random grouping function, a constant grouping function and a selection/sealing function for additionally enclosed papers. The random grouping function reads the encoded mark printed on enclosed papers in accordance with predecided rules and groups a random number of enclosed papers. In the meantime, the selection/sealing function for additionally enclosed papers supplies additional enclosed papers 101 to the enclosed paper 92 by reading an encoded mark on the enclosed paper 92. The grouped enclosed papers 92 and additionally enclosed papers 101 are supplied to an enclosed paper feeder mechanism.
