MARK SHEET COMMUNICATION SYSTEM

摘要

PURPOSE:To obtain a mark sheet communication system covering the recognition accuracy of a converting device which converts a pattern signal to a code signal by sending out the pattern signal of a mark sheet from a communication network to an information processer after the request signal of a network pattern signal is sent from the information processing device. CONSTITUTION:An information processer 2 executes the fetching process of a code signal received from a communication network 4 through a signal buffer 12 on the communication network side into a central processing unit 13. When the abnormal condition of the code signal is found out at the central processor unit 13, a pattern signal corresponding to the code signal received from the communication network 4 is outputted to a facsimile device 14 or a display device 15 and it is possible to cope with the abnormal code signal, for instance, by judging person's eyes. Thereby, a mark sheet communication system covering the recognition accuracy of PTCE 6 is realized.
