A reading machine is provided comprising a carriage for temporarily receiving and retaining a publication such as a book, magazine or printed sheet, which carriage is slidably inserted into tracks supported by the main body of the reading machine so as to allow horizontal movement of the carriage relative to the main body of the reading machine. A continuous belt is supported by roller bearings disposed about the main body of the reading such that the belt covers the carriage when the carriage is attached to the reading machine. The belt includes a horizontal member having an opening therein, said opening extending through the belt itself and being of substantially the same size of a line of text such that the opening and belt may be used to isolate individual lines of text. The machine includes control means that include means for manually or automatically controlling the vertical displacement of the belt and the horizontal member by means of an electric motor or by means of a knob or handle.
