摘要： 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.

摘要： Between adjacent pinch rollers 22, an auxiliary roller 44 is provided coaxially with the pinch rollers 22. A large diameter portion 44a of the auxiliary roller 44 presses down a recording medium on a platen 12. Between the auxiliary roller 44 and an image formation zone 41, there is provided a downstream sheet-pressing member 46. The large diameter portion 46a of the downstream sheet-pressing member 46 also presses down the recording medium against the platen 12.
