摘要： A PAGE TURNING DEVICE AND A MANUSCRIPT FOR USE THEREWITH WHICH COMPRISES A STAND FOR SUPPORTING THE MANUSCRIPT. SAID STAND CARRIES A LEVER WHICH IS PIVOTALLY MOVABLE FOR CYCLIC OPERATION EFFECTIVE TO TURN A PAGE 180* THE DISTAL END OF THE LEVER IS PROVIDED WITH A SLEEVE MEMBER THROUGH WHICH A SHAFT IS LONGITUDINALLY MOVABLE. MEANS ARE PROVIDED ON THE SLEEVE MEMBER TO RETAIN THE SHAFT IN POSITION AND IS MOMENTARILY RELEASED WHEN THE LEVER MEMBER IS PIVOTED TO TURN THE PAGE 180* TO ALLOW THE SHAFT TO DROP BY GRAVITY A SPACED DISTANCE AT WHICH POINT THE SHAFT IS REGRIPPED. A MAGNET IS PROVIDED AT THE

DISTAL END OF THE SHAFT WHICH FUNCTIONS TO HOLD A MAGNETICALLY ATTRACTABLE ELEMENT CONNECTED TO EACH SHEET OF THE MANUSCRIPT AT A LEVEL SPACED DOWNWARD FROM AND IN VERTICAL ALIGNMENT WITH A MAGNETICALLY ATTRACTABLE ELEMENT CONNECTING A PRECEDING SHEET. THE VERTICAL SPACING BETWEEN THE MAGNETICALLY ATTRACTABLE ELEMENTS ON ADJACENT SHEETS IS EQUAL TO THE INCREMENT THAT THE SHAFT IS LOWERED DURING EACH CYCLE.
