Abstract:
1. A paper cutter, wherein to-be-cut paper placed on a base is press-held by a straight-rod-like paper holding member, which is supported on the base and is vertically movable; and the to-be-cut paper is cut with moving a cutting blade along the paper holding member; four-joint link array mechanisms are provided, each of the four-joint link array mechanisms comprising a first pivotal link swingably supported on a side of a final cutting position of the base, a second pivotal link swingably supported on a side of a cutting starting position of the base, and a connecting link rotatably supported between a free end of the first pivotal link and a free end of the second pivotal link and attached to the paper holding member along a face on a side opposite to a pressing face of the paper holding member; and the paper holding member is moved in a same direction with a moving direction of the cutting blade; the four-joint link array mechanisms include first and second four-joint link array mechanisms disposed in parallel along the paper holding member; the first and second 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; and in association with pivotal movements of the first and second pivotal links disposed to intersect with each other, the respective four-joint link array mechanisms move the respective connecting links in opposition to each other in a longitudinal direction.
