  • Patent number: 9284139
    Abstract: A sheet feeding device includes an attracting mechanism and a changing mechanism. The attracting mechanism includes a lifting section and a maintaining section. The lifting section attracts a portion of a sheet material that is fed and lifts the portion of the sheet material. The maintaining section attracts an edge of the sheet material that is lifted by the lifting section and maintains an orientation of the edge of the sheet material. The changing mechanism changes at least one of an attraction force that is generated at the lifting section and an attraction force that is generated at the maintaining section.

  • Patent number: 7841590
    Abstract: An image forming apparatus includes: a first feeding unit and a second feeding unit. In the first feeding unit, a hand-feeding unit having a hand-feeding accommodating portion is mounted. The first feeding unit includes a first mounting portion into which a medium is conveyed from the hand-feeding accommodating portion. And a connection unit for consecutive installation is mounted to the first mounting portion in a state where the hand-feeding unit is removed from the first mounting portion. The connection unit includes an added conveyance path for consecutive installation. The second feeding unit includes a second mounting portion in which the hand-feeding unit is mounted and into which a medium is conveyed from the hand-feeding accommodating portion. And the second feeding unit is connected to the added conveyance path.

  • Patent number: 6335570
    Abstract: A semiconductor device capable of preventing diffusion of a particle of copper or the like which forms a conductive layer is provided without any increase in the number of manufacturing the steps. Further, a semiconductor device preventing diffusion of a particle forming a conductive layer into an insulating layer even when a width of the conductive layer is increased is provided. The semiconductor device includes: an insulating layer 2; a barrier layer 4; a conductive layer 5; a barrier layer 6 having an opening 11; an insulating layer 7 having a through hole 8 exposing a surface of conductive layer 5 and a part of a surface of barrier layer 6; a barrier layer 9 formed on a surface of said through hole 8 and insulating layer 7 which is in contact with an upper surface 6a of barrier layer 6; and a conductive layer 10 filling opening 11 and through hole 8.

  • Patent number: 6215189
    Abstract: A highly reliable semiconductor device having a contact hole with a sufficient area can be obtained. An interlevel insulating film is formed on a conductive region having a first width. A through hole which exposes the conductive region is formed at the interlevel insulating film. A coating film is formed on the interlevel insulating film. In the coating film, an opening having a second width larger than the first width is formed in a region located on the through hole. An interconnect line is formed in a region located on the opening. A conductor film for electrically connecting the conductive region and the interconnect line is generated within the through hole.
