A copier control and record keeping method and system including one or more computer terminals (66) connected to and communicating with a central recorder (60), each terminal (66) having a data base capability and means for memory features for storage of information and sensing authorized access, means for counting the numbers of original and copies made, and means for accumulating data for transmission of the data to a recorder (60), such transmission being effected only when both completion of a cycle and the removal of a coded card from the terminal (66) receptacle have occurred. The apparatus includes means for monitoring and for acknowledging received messages, and a time-delay, keyed priority sensing system for recognizing and identifying each of the terminals (66) and for preventing transmission interference between the various terminals (66) all of which are connected to transmit information to the central recorder (60) on the same line (62). Additional features and capabilities of the apparatus include means for transmitting service requests to the central recorder (60), means for controlling automatically the maximum number of copies that can be made of each original, and means for entry of ancillary data such as the size of the original being copied, and data identifying the party or account to be billed for the copies made. |
