  • Patent number: 6796559
    Abstract: In an automatic document feeder for use in an image forming device such as copy machine and facsimile machine: a document shunting path for temporarily shunting a document is provided at an upstream side of a document reading portion; in a different-size mixed mode where different sizes of documents are placed in a mixed manner, the leading edge and rear edge of the document are detected by a sensor during conveyance of the document in the direction toward the document reading portion, so that the length of the document is detected; thereafter the document is conveyed in the reverse direction so that the rear edge of the document is shunted into the document shunting path; and thereafter the document is again conveyed in the forward direction to conduct reading. Thus, it becomes unnecessary to provide a longer conveyance path for detecting the length of the documents, so that the size of the feeder itself can be reduced.

  • Patent number: 6283354
    Abstract: A sheet processing apparatus has a function of stapling sheets together, wherein the sheets are fed from an image forming apparatus one by one after images are formed on the sheets. The sheet processing apparatus includes a stapler to staple the sheets together, a sheet guide which guides the sheets along a sheet transporting path from the image forming apparatus to a position at which the sheets are stapled by the stapler, and a reference surface against which edges of the sheets are butted to stop movement of the sheets. The sheets are guided along the sheet transporting path by the sheet guide and the edges of the sheets are butted against the reference surface at a same position relative to a sheet conveying direction, irrespective of whether the sheet processing apparatus is in a stapling mode in which the stapler staples the sheets or a non-stapling mode in which the stapler does not staple the sheets, and irrespective of sizes of the sheets.
