Electronic advertising and information writing system

摘要

Known electronic information systems output their information using a display screen. A print-out is available. Locational data must be described using "geometrical techniques", for example coordinates. The device is intended uncomplicatedly to write the desired information and to display the locational data in a graphical representation. The device, in various forms with electronic computer and programme, electronic printer, paper feeder, keyboard with display and output slot, writes, after a code has been input, an information item and the corresponding locational data as a symbol in a graphical representation. If this is located on the rear, then the symbol lies on the front exactly over the corresponding location. If the symbol is pierced, the hole on the rear constitutes the locational datum. The device is suitable as an information source and advertising medium for displays having specific locational data, especially in the field of tourist information and hotels.
