TERMINAL APPARATUS

摘要

A printing terminal apparatus for data transmission is adapted to transmit at the beginning of each message sent to a central computer, a code combination indicative of the terminal operator and to print characters corresponding to said code combination in a predetermined position on the paper at the printing terminal. The code combination is automatically generated at the start of the message by inserting a lock-key into a corresponding lock and by depressing a key associated with the inserted lock-key.
