Information recording system capable of protecting secrecy

摘要

A plurality of sheet hoppers and a plurality of output stackers are provided so that sheets of paper are selectively output from a specific sheet hopper. The printed sheet is output to a specific output stacker according to a type of document to be printed. The specific output stacker can be selected based on a control signal from a computer or a signal from a mark discrimination sensor, and the printed sheet of a confidential/secret document can be output to the specific output stacker even if a general document and a confidential/secret document are both printed by a single recording apparatus.
