Patent number: 10384890Abstract: A paper feeding device of an embodiment includes a paper feed tray, a blower, and a flow regulating member. A paper bundle in which a plurality of sheets of paper are stacked can be placed on the paper feed tray. The blower is positioned next to the paper bundle placed on the paper feed tray. The blower can generate airflow. The flow regulating member is positioned above the paper bundle placed on the paper feed tray. The airflow from the blower causes the flow regulating member to generate a negative pressure between the flow regulating member and the uppermost sheet of paper of the paper bundle.Type: GrantFiled: March 5, 2018Date of Patent: August 20, 2019Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA TEC KABUSHIKI KAISHAInventors: Kei Matsuoka, Shinichi Tatsuta, Shunsuke Hattori, Takamitsu Sunaoshi, Yusuke Hashizume, Masakazu Iwamoto

Patent number: 8203767Abstract: An auto document feeding device causes an original document passing through an OUT path and an original document passing through an IN path to flow together with overlap a trailing edge of a preceding original document and a leading edge of a following original document. Before the original documents reach to a READ document glass, the auto document feeding device comprises a separating unit configured to separate an overlapping portion of the original documents. The auto document feeding device reduces a distance between the preceding original document and the following original document passing on the READ document glass to nearly 0 mm.Type: GrantFiled: November 2, 2009Date of Patent: June 19, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventors: Osamu Kitazawa, Masakazu Iwamoto, Seiji Iino, Akihito Tokutsu, Shinichi Miyakawa, Mitsunori Ishii

Patent number: 8199383Abstract: The lengths of an OUT path and an IN path are made longer than the length of a document of a main size in a traveling direction. The document of the main size stands by for conveyance in a direction of a READ document glass in a state where the entire document is contained in the OUT path or the IN path. The entrance speed of the document into the OUT path or the IN path is equal to the read speed of a scanner. The leading edge of a subsequent document is overlapped on the trailing edge of a preceding document, and the document is conveyed to the READ document glass.Type: GrantFiled: June 26, 2009Date of Patent: June 12, 2012Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventors: Akihito Tokutsu, Seiji Iino, Mitsunori Ishii, Masakazu Iwamoto, Shinichi Miyakawa, Osamu Kitazawa
