  • Patent number: 5508799
    Abstract: A method and apparatus for punching holes in a stack of sheets using a hole puncher. The method includes the steps of activating the hole puncher, determining whether the hole puncher has completely punched a hole in the stack of sheets, and repeating the activating step in response to the determining step until the hole punching is successful. The method also includes determining whether a reference number of unpunched sheets, which is not greater than a single punch capacity of the hole puncher, has been stacked. Upon determining that the reference number of sheets has been reached, the method includes discontinuing the stacking of further sheets and applying a punching operation to the reference number of sheets. The method also includes reinitiating the stacking operation if the number of sheets to be stacked is greater than the reference number of sheets. The invention also includes an apparatus for carrying out the noted method steps.

  • Patent number: 5186445
    Abstract: A sheet handling apparatus is provided adjacent to an image forming apparatus. The sheet handling apparatus staples sheets discharged from the image forming apparatus, and it includes a plurality of bins, a stapler, a discharge mechanism, and a stack tray. The sheets are stapled while they are nipped by the discharge mechanism. The bins store the sheets supplied from the image forming apparatus. The stapler staples the sheets stored in the bins. The discharge mechanism discharges the stapled sheets from the bins frontward with respect to the image forming apparatus, where an operator normally stands. The sheet storer is conveyable in both a vertical and a lateral direction. The stack tray is located alongside the front of the image forming apparatus, and stores the sheets discharged by the discharge mechanism.

  • Patent number: 5156390
    Abstract: An automatic document conveying device for an image processing machine in which a transparent plate, on which to place a document to be processed, is disposed on the upper surface of the housing. The automatic document conveying device includes a document table for holding documents to be processed, a document receiving tray for receiving documents after they have been processed, and means for feeding documents from the document table through the processing to the document receiving tray. A document delivery roller moves the document from the transparent plate, following processing of the document, along a document delivery passage. Document discharge rollers located at the downstream end of the document delivery passage move the document from that point to the document receiving tray. The document delivery rollers are driven at a higher speed than are the document discharge rollers.
