<p>There is provided a recording material cutting device having a mechanism for cutting a recording material by the whole edge of a cutter blade so as to prolong the service life of the cutter blade, while allowing to simplify the structure of the device, to downsize the device, and to improve the straightness of the cut portion of the recording material. Upon starting the cutting, the cutting-in depth of the cutter blade 130 is the deepest, and the recording material 113 is cut by the near-root portion of the cutter blade 130. As the whole of the cutter unit 112 moves in the direction C while the seizing member 123 abuts onto the cammed surface of the cammed portion 132, the cutter holder 122 is gradually lifted up so that the cutting-in depth of the cutter blade 130 into the recording material 113 is gradually shallowed. Upon reaching the raised center of the cammed portion 132, the height of the cutter holder 122 becomes the maximum while the cutting-in depth of the cutter blade 130 becomes the minimum, so that the cutter blade 130 cuts the recording material 113 at the near-tip portion of the cutter blade 130. As the cutter unit 112 further travels to the right, the cutting-in amount of the cutter blade 130 becomes gradually deep again. <IMAGE></p> |
