发明名称 Computer read-out book stand
摘要 A computer read-out book stand is disclosed. The stand has a rectangular base with a rectangular book support adjustably attached at the base's midpoint. The book support is angularly elevated by a set of elevators of graduated heights. A retaining means on the book support's distal end connects a selected elevator to the book support. L-shaped posts fastened to the book support, and parallel to its sides, receive the slotted ends of book spine holders so that the book remains in place, resting on the book support at the desired angle.
