  • Publication number: 20080112021
    Abstract: A copier includes an ADF that transports electronic paper and a paper medium to a read position. The ADF includes a medium type detector, a controller, a communication reader, and an optical reader. The medium type detector discriminates between electronic paper and a paper medium. The controller controls transport of electronic paper and a paper medium. The communication reader reads electronic data stored in the electronic paper at the read position. The optical reader optically reads an image on a paper medium at the read position to obtain electronic data.

  • Patent number: 7364039
    Abstract: In a packing member that packs an ink cartridge, the packing member is constituted as an adhesive label, a perforation is provided on a portion of the label, an ink cartridge is packed by adhering the label on the cartridge, and the ink cartridge is unpacked by peeling off a central portion of the label along the perforation. A back sheet (release coated paper) of the label is adhered on the ink cartridge in a state in which a portion of the back sheet is left. Thus, unpacking (peeling-off of the label) is facilitated, and adhesive is prevented from remaining.

  • Patent number: 7303275
    Abstract: An inkjet recording device, includes a recording head configured to discharge a liquid drop of recording liquid in a horizontal direction or in a vertically lower direction than the horizontal direction; and a conveying part configured to convey a recording medium so that a recording surface faces the recording head when the recording medium passes a liquid drop discharge area of the recording head. The recording medium is discharged, after the recording medium is conveyed in a curved state so that the recording surface where the liquid drop discharged from the recording head is adhered faces in a vertically lower direction than the horizontal direction, by the conveying part. The conveying part includes a surface moving member configured to make a moving surface of the surface moving member come in contact with an external circumferential surface of a curved part of the recording medium so as to give a conveying force to the recording medium by a friction force.
