Abstract

PURPOSE:To prevent the mischief or the like given by the third person with a simple constitution by transmitting the specific hidden codes differing with every terminal unit memorized to the center from the transmitting part via the circuit. CONSTITUTION:The specific hidden codes which differ every terminal unit memorized in memory unit 3 is transmitted to circuit A from network control unit 9 as well as to hybrid circuit 8 from transmitting circuit part 7 via switched contact C of switch circuit 6 to be collated at the center. In this case no output is transmitted to the display part of print part 5. Thus, the mischief or the like given by the third person can be prevented.
