摘要： A reading guide includes first and second reading directors oppositely positioned at terminating ends of the reading guide. A separation section having a predetermined separation length, on the longitudinal axis of the reading guide, separates the reading directors. Both directors have beveled end edges, the first director having an end edge width which is less than the end edge width of the second director. The beveled end edge of the first director is formed by a double taper, the angles of the two tapers with respect to the longitudinal axis being unequal. Similarly, the beveled end edge of the second director is formed by a double taper, the angles of these two tapers with respect to the longitudinal axis, however, are equal. In the separation region the reading guide has curved sides, which may be sections of a circular, ellipse, or any other curve, which extend the length of the separation region. Between these curved sides are first and second planar surfaces, which also extend the length of the separation region, one of these planar surfaces contains two groves into which the thumb or a finger may be selectively positioned when the reading guide is held in position for reading.
