Japanese Patent JP3356774

B2

PURPOSE:To obtain a small device at a low cost by mounting a movable guide which can move in accordance with the magnitude of a force generated when a page is turned over during a page turn-over action to vary a buckling length. CONSTITUTION:A page turn-over roller l rotates in a direction B. A frictional part la of the roller comes into contact with a page to be turned over, and the page begins rising. At this time, a mechanical boundary for deforming the page depends on the position of a movable guide 11. The position of the movable guide 11 depends on a pressing-up force Fl at a contact point 14 of a rising page 13a with the movable guide 11. When an initial load F2 acts on the movable guide 11 at the contact point 14 by a spring 12, a mechanical boundary is established at a tip end 11a of the movable guide 11 in the condition of F1
