Abstract
A paper cutting device, for cutting multiple sheets of paper stacked in layers on a table, comprises a paper retainer (2) descending from an upper side along a guide and a cutter (3) diagonally ascending from the lower side. A receiving part (18) is mounted on the lower surface of a paper retaining frame (20). The receiving part (18) is formed by joining a base plate (36) with a large elastic modulus such as a metal to a resin receiving plate (37). A slip prevention structure is installed on the junction surfaces of the base plate (36) and the receiving plate (37) to suppress the extension/retraction of the receiving part of the paper retainer so as to prevent wrinkles from occurring in the paper near a blade receiving surface when the paper is cut off.
