OUTPUT SYSTEM FOR TRANSACTION DATA

PURPOSE:To allow one terminal device to read the transaction data of another terminal device by providing the terminal device with a command means which requests to a controller the transaction data of the other terminal device. CONSTITUTION:When totalization data of, for example, an electric register 1b is read from an electronic register 1a, a totalization data request button 17a on a keyboard part 17 is pressed and an equipment number of the electronic register 1b is inputted; and a button identification part 9 identified the number to set an FF11, and a request signal generation part 10 sends a request signal for the corresponding to the equipment number, which is transmitted from a transmission part 18 to a terminal controller (T/C) 2 through a private line. When the reception part 22 of the T/C2 receives the request signal, it is identified by a receive signal identification part 24 to set an FF26 and also sent to a file control part 27, which reads the totalization data of the electronic register 1b out of a totalization file part 20 and transmits it from a transmission part 23, so that the data is received by the reception part 19 of the electronic register 1a through the line.
