Abstract

A paper cutter comprising a pair of four-joint link array mechanisms disposed in parallel between a paper holding member and a base, wherein pivotal links adjacent between the respective four-joint link array mechanisms are disposed to intersect with each other and to be slanted in directions opposite each other; in association with pivotal movements of the pivotal links, connecting links move in opposition to each other in a longitudinal direction; a downward operation force of the paper holding member acts as a pulling force on the respective connecting links; vertical movement of the paper holding member is constantly maintained in a parallel state with respect to the base; and a substantially uniform pressing force is imparted in a longitudinal direction of the paper holding member in cooperation with the vertical movement of the paper holding member.
