Patent number: 7467794Abstract: A sheet conveyance release mechanism has a movable guide unit and a fixed guide unit adjacent to the movable guide unit. The mechanism has a horizontal conveyance guide unit for conveying a sheet in a substantially horizontal direction, and a vertical conveyance guide unit for conveying a sheet in a substantially vertical direction. A jam release lever moves the movable guide unit from a first position adjacent to the fixed guide unit in the horizontal direction to a second position below the fixed guide unit, and moves the vertical conveyance guide unit so as to separate from a guide surface.Type: GrantFiled: April 26, 2006Date of Patent: December 23, 2008Assignee: NISCA CorporationInventors: Ichitaro Kubota, Daisuke Kaneoya, Kunihide Suzuki

Patent number: 6837488Abstract: The document feeder apparatus is equipped with a sheet supply unit including a sheet supply member for supplying an original to a reading position; a transport unit including a transport member for receiving the original from the sheet supply member and transporting the original to the reading position; a discharge unit including a discharge member for discharging the original read at the reading position; and a flat plate shape support frame for supporting the respective units. The sheet supply unit and discharge unit are mounted on one of front and rear sides of the support frame, and the transport unit is mounted on the other of the front and rear sides of the support frame, so that each unit is unitized. Further, a sheet supply opening for guiding the original from the sheet supply unit to the transport unit is established on one side of the support frame, and an opening for guiding the original from the transport unit to the discharge unit is established on the other side of the support frame.Type: GrantFiled: June 6, 2002Date of Patent: January 4, 2005Assignee: Nisca CorporationInventors: Atsumi Kobayashi, Kunihide Suzuki, Yutaka Tanaka, Akiharu Higaki, Akihiko Tukui, Mizuho Shirakura

Patent number: 6810231Abstract: A sheet transfer apparatus transfers a sheet to a predetermined position. The apparatus includes a discharge tray; a support device for rotationally supporting the discharge tray; an interconnecting device that activates according to a rotation of the discharge tray; and a sheet regulating device engaging the interconnecting means to be movable between a regulating position for regulating a movement of the sheet and a retracted position for allowing the sheets on the discharge tray to move. A control device prevents the sheet regulating device from moving to the regulating position from the retracted position even though the discharge tray is rotated when a load greater than a predetermined value is applied to the sheet regulating device.Type: GrantFiled: March 27, 2003Date of Patent: October 26, 2004Assignee: Nisca CorporationInventors: Atsumi Kobayashi, Kunihide Suzuki, Yutaka Tanaka, Akiharu Higaki, Akihiko Tsukui, Mizuho Shirakura

Patent number: 6618575Abstract: An automatic document feeder of the invention has a conveying roller for conveying a document sheet to a document reading position on a platen facing a document image reading portion. The automatic document feeder contains a pickup guide for picking up the fore end of a document sheet scanned at the document reading position and a pressing piece for pressing a document sheet being conveyed against the pickup guide at a curved portion provided by the platen and the pickup guide. The pressing piece is fixed at an upstream side of the document reading position, extending from the fixed position across the document reading position and is made free at a downstream portion. Further, this document feeder is provided with a document sheet deflecting device for deflecting a document sheet toward a paper discharge stacker. The document deflecting device is a plate spring being capable of swaying within a specified range.Type: GrantFiled: March 22, 2001Date of Patent: September 9, 2003Assignees: Nisca Corporation, Toshiba TEC Kabushiki KaishaInventors: Norio Takida, Takao Imamura, Naoki Shoji, Seiji Iino, Mizuho Shirakura, Kunihide Suzuki, Ryuta Komatsu

Patent number: 6601842Abstract: A sheet transfer apparatus for an image reading apparatus includes a sheet supply tray for storing a sheet; a sheet supply device for drawing out the sheet on the sheet supply tray; a transfer device for receiving the sheet from the sheet supply means and placing the sheet at a predetermined position on a platen of an image reading apparatus for reading the image thereon; a discharge device for discharging the sheet on the platen after reading the image thereon; and a discharge tray for receiving the sheet discharged by the discharge device. A switchback device is disposed above the platen for reversing the sheet when necessary, and includes a switchback path for receiving the sheet to reverse the same. The switchback path includes a first opening portion for opening a first area near an inlet side, and a second opening portion for opening a second area away from the inlet side of the switchback path. The switchback path is easily accessible when the sheet is jammed.Type: GrantFiled: May 2, 2002Date of Patent: August 5, 2003Assignee: Nisca CorporationInventors: Atsumi Kobayashi, Kunihide Suzuki, Yutaka Tanaka, Akiharu Higaki, Akihiko Tsukui, Mizuho Shirakura
