ABSTRACT:
A hand-held, manually operated book index notch cutter is placed in the book to be notched. The notch cutter has a cylindrical cutting member (405) which moves parallel to and rotates around its axis. The axis of the cylinder is perpendicular to the book leaves being notched. The cutting member rotates and advances within a cutter guide (200), which is attached to a thin baseplate (100). The upper surface of the baseplate is a resilient platen (102) on which rests the stack of book leaves to be cut. These leaves are adjusted in fan and lateral angle with the help of a leaf guide (300), which is movable to allow a range of notch depths. The cutting member is attached to a knob (401) which is pressed and turned. Inside this cutting member-knob assembly is a spring-loaded ejector assembly (500). After a notch is cut, the ejector button (501) is pressed, capturing the paper cuttings and raising the cutting member to the ready position. Then the entire index notch cutter is removed from the book and placed over a wastebasket, and the ejector button is released, causing the paper cuttings to fall.
