Abstract
Abstract A scanning system is disclosed in which a multiplicity of points arranged in matrix are scanned column by column in accordance with the commands issued from a central controller, which scanning system comprises a memory and a scanning controller for scanning in sequence a plurality of the scanning points designated by the central controller and storing the results of the scanning in the memory sequentially. The information stored in the memory is read out from time to time by the central controller as required.
