  • Patent number: 10065829
    Abstract: A sheet post-processing device for, after sheets that are ejected from an image forming device are stored on a storage tray, transporting the sheets in a transport direction to a post-processing position and performing post processing at the post-processing position, including: an aligner configured to align sheets on the storage tray; and a transporter configured to transport to the post-processing position a stack of sheets aligned by the aligner. The transporter includes a first contact member and a second contact member, and transports the stack to the post-processing position by causing the first contact member and the second contact member to simultaneously move in the transport direction while causing the first contact member to be in contact with a rear end portion of the stack in the transport direction and the second contact member to be in contact with a leading end portion of the stack in the transport direction.

  • Patent number: 9609158
    Abstract: An image forming device having a printer unit, a post-processing unit, and an eject tray. The printer unit forms images on recording sheets, and the post-processing unit performs processing on a recoding sheet stack composed of one or more recording sheets output from the printer unit before the recording sheet stack is ejected onto the eject tray. The image forming device includes: a buffer unit that, while a first recording sheet resides in the post-processing unit for the post-processing, holds a second recording sheet therein, the second recording sheet output from the printer unit subsequent to the first recording sheet; and a reverse path that reverses recording sheets when the image forming device performs duplex printing. In a plan view of the image forming device taken along a vertical direction, the post-processing unit, the buffer unit, and the reverse path at least partially cover one another.
