The invention concerns a data entry system in which data read by an operator from a source information carrier is fed by signals from a keyboard by the operator into a data processing machine and in which operator instructions concerning the keying of the source data are produced by the data processing machine and are visually displayed to the operator on a visual display device. According to the invention the visual display device is located in juxtaposition with the source information carrier and the visually displayed operator instructions.
