  • Patent number: 10328595
    Abstract: A post-processing apparatus includes a storing unit in which plural recording media are stored for performing post-processing, and a pushing member that latches onto and pushes trailing ends of the recording media stored in the storing unit toward an ejection port. When the number of the recording media stacked on the storing unit is small, the pushing member latches onto and pushes the trailing ends of the recording media at a position different from a position at which the pushing member latches onto and pushes the trailing ends of the recording media when the number of the recording media stacked on the storing unit is large.
    Type: Grant

  • Patent number: 10274886
    Abstract: A post-processing apparatus includes a storing unit in which plural recording media are stored for performing post-processing and a transport member that transports a recording medium to the storing unit as a result of rotating while being in contact with a surface of the recording medium. The transport member includes a blade that comes into contact with a recording medium and a reinforcing portion that reinforces a strength of a portion of the blade that does not come into contact with the recording medium.

  • Publication number: 20150008641
    Abstract: Provided is a post-processing device including a first stacking member on which recording materials are stacked, an extension member that is connected to one end side of the first stacking member and that supports the recording material, and a second stacking member on which plural recording materials are stacked as a recording material bundle and which is placed so as to be movable in a direction intersecting a discharge direction of the recording material bundle, wherein the extension member is connected to the first stacking member so as to be non-rotatable in a direction approaching the second stacking member and be rotatable in a direction away from the second stacking member.
