The file can be accessed from a number of remote points, with the information documents recorded on each file card scanned by a video camera, for video transmission of the required information to a display monitor at the remote point. The latter each have a keyboard for entering the code address of the required information used to select the correct card and to bring the area of this card containing the correct document in front of the video camera. The displacement of the selected card in at least two different directions is pref. controlled via stepping motors, e.g. under microprocessor control.
