  • Patent number: 8896854
    Abstract: An image reading apparatus with a structure capable of reliably discharging a document, and a multi-functional machine having the same are disclosed. The image reading apparatus includes a document feed path having a document outlet, a reading unit which reads an image of a document fed through the document feed path, and a guide member which is disposed at the document outlet downstream of the reading unit to form a curl on the trailing end portion of the document. The curl formed on the document may make it possible for a subsequent document being discharged to push the curled document out of the document outlet.

  • Patent number: 7267501
    Abstract: An image forming apparatus includes an image forming unit that prints an image on a medium. A transport unit transports the medium in a first direction to supply the medium to the image forming unit, and in a second direction for printing. Media is stacked on a paper cassette. A medium supply and discharge unit picks up the medium from the paper cassette to supply the medium to the transport unit, and discharges the medium being transported in the second direction. The transport unit, the paper cassette, and the medium supply and discharge unit are located at the second direction of the image forming apparatus.
