A PERFECTED ATRIL FOR READING, essentially characterized by the fact that along the screen-support are placed Solomonic columns on which there are coupled cylindrical ferrules equipped with radial retaining elements, between which is fixed a tape or thread that slides along with the bushes on the front face of the board or screen; both columns being related to each other by a sliding cable on pulleys in which the columns end; and being supported one of the columns on a pinion, free rotation in one direction, driven by a lever whose point of support is the axis of the column and whose subsequent extension slides on an arc in which an adjustable stop is set to will that determines the greater or lesser travel of the lever and therefore the vertical sliding of the tape or thread that indicates the lines to read or transcribe.
