Definitions

  • the invention relates to a document input device such as a scanner, copy machine, or fax, and it also relates to the automatic document feeder mounted to a document input device to convey documents or paper into the document input device.
  • this invention relates to document input devices that are small enough to be used on a desktop. More specifically, the invention relates to automatic document feeders that can accommodate multiple sized sheets.
  • the term "scanner” is used to mean "document input device,” thus encompassing any device that inputs paper or paper documents.
  • the scanner 100 comprises an input tray 101 for holding documents to be fed into the scanner for scanning and an output tray 102.
  • the input tray 101 includes a pair of edge guides 151 and 152 located on the edges of the input tray.
  • the guides 151 and 152 guide letter-sized documents through the scanner and prevent them from skewing when they pass from the input tray 101 through the scanner and to the output tray 102.
  • the scanner 100 is shown having a plurality of multiple-sized sheets 200 loaded in the input tray 101 for feeding into the scanner.

  • the letter-sized document 310 has been fed through the paper path and is resting in the output tray 102.
  • the letter-sized document has fed straight and has not become skewed during feeding due to the edge guides 151 and 152 which are located and sized such that the edges of the letter-sized document 310 abut the guides 151 and 151, prevented a skewed feed.
  • the receipt-sized sheet 311 is also shown exiting the sheet feeder 202.
  • the guides 151 and 152 are sized for the letter-sized document 310, there are no guides for the size of a receipt-sized sheet. As a result, the receipt-sized sheet 311 becomes skewed as it passes through the paper path. Similarly, the business card-sized sheet 312 also skews in the absence of suitable guides to keep it in place and fed straight through the sheet feeder 202.
