INFORMATION DISPLAY SYSTEM

PURPOSE:To display information relating logically out of a large amount of information at high speed by providing an information call means which calls the information not stored in a display information storage means out of the information relating to displayed information from an information accumulation means and stores it in the display information storage means. CONSTITUTION:The information call means 6 is provided which calls and displays the information on a display means 4 when the information instructed by a display information instruction means 3 is stored in the display information storage means 5, and calls and displays it from the information accumulation means 2 when it is not stored, and also, calls the information not stored in the display information storage means 5 out of the information relating to the displayed information from the means 2 and stores it in the display information storage means 5. In such a way, the information relating to the displayed information is called from the information accumulation means 2 for the next processing and is stored in the display information storage means 5, and the display information storage means 5 is realized with semiconductor memory capable of performing a fast call. In such a way, it is possible to read out the information relating logically out of a large amount of information at high speed.
