SCISSORS, CUTTER MACHANISM INCORPORATING THE SCISSORS AND PRINTING APPARATUS INCORPORATING THE CUTTER MECHANISM

摘要

Scissors include a first cutting blade, a second cutting blade and a support shaft. The first cutting blade has a handle and is formed with a through hole. The second cutting blade has a handle and is formed with an insertion hole. The support shaft extends through the through hole of the first cutting blade and the insertion hole of the second cutting blade, for pivotally connecting the first cutting blade and the second cutting blade in a manner such that the first cutting blade and the second cutting blade can perform relative rotation about the support shaft with respect to each other to thereby perform a cutting operation. The second cutting blade has a spring nut portion formed in the form of a spring nut on an inner peripheral surface of the insertion hole. In another form of the invention, scissors include a pair of cutting blades each having a handle and arranged for relative rotation thereof with respect to each other to thereby perform a cutting operation, the pair of cutting blades each having a cutting edge and a cutting face parallel with the cutting edge, and a pivot member about which the pair of cutting blades perform the relative rotation. Each of the cutting blades has a bent portion along the cutting edge, the bent portion formed by bending a portion including the cutting face toward an opposed one of the cutting blades at a predetermined angle.
