Patent number: 8572812Abstract: A foldable portable information terminal includes an upper unit having a display unit on its one side, a lower unit having operation keys on its one side, and a movable connecting mechanism connecting the upper unit and the lower unit allowing the upper unit to be opened, closed, and freely rotated with respect to a longitudinal direction of the lower unit. The displaying mode of the display unit whose direction varies depending on a position of the upper unit is changed depending on a positional relationship of the upper unit and the lower unit.Type: GrantFiled: October 21, 2008Date of Patent: November 5, 2013Assignee: NEC CorporationInventors: Masatomo Mizuta, Kazuo Ohtsuta, Kiyoshi Kohayakawa, Michio Nagai, Mika Fujii, Masaki Shimamura, Mitsuru Sendouda

Patent number: 8082633Abstract: A portable device includes an upper unit, a lower unit having an operation section on an operation surface, and a movable connecting mechanism which connects the upper unit and the lower unit. The movable connecting mechanism includes a rotating hinge including a rotation axis which is securely and rotatably provided to the lower unit and which protrudes from the operation surface in a direction substantially normal to the operation surface, a projection protruding outward from the rotation axis, and a stopping member provided at a location where the projection comes in contact with the stopping member due to rotation of the rotation axis. The stopping member is movable within a predetermined range of movement due to the projection coming in contact with the stopping member.Type: GrantFiled: October 8, 2010Date of Patent: December 27, 2011Assignee: NEC CorporationInventors: Masatomo Mizuta, Kazuo Ohtsuta, Kiyoshi Kohayakawa, Michio Nagai, Mika Fujii, Masaki Shimamura, Mitsuru Sendouda

Patent number: 7320153Abstract: A fold-type cellular phone has a top unit, a bottom unit and a hinge coupling together the top unit and the bottom unit while allowing the top unit to turn and swivel with respect to the bottom unit. The top unit is first unfolded from a first folded position to an attitude angle of 160 to 170 degrees, and swiveled by 180 degrees to be folded onto the bottom unit in a second folded position at an attitude angle of 180 degrees. The swivel movement of the top unit causes a cam assembly to turn the top unit from the attitude angle of 160-170 degrees to an attitude angle of 180 degrees in the second folded position, thereby allowing the top unit to assume a suitable attitude with respect to the bottom unit.Type: GrantFiled: June 15, 2006Date of Patent: January 22, 2008Assignee: NEC CorporationInventors: Yosuke Watanabe, Masatomo Mizuta, Mitsuru Sendouda

Patent number: 7158816Abstract: A foldable and portable mobile communication terminal is formed as a two-folded type in which a lower-side body unit and upper-side unit are coupled openably and closably by a two-shaft hinge mechanism. The two-shaft hinge mechanism includes a first hinge unit that allows the upper-side body unit to rotate with respect to the lower-side body unit up to the open state defining a predetermined talking position, and a second hinge unit that allows the first hinge unit to rotate in a direction different from the aforementioned rotational direction of the first hinge unit. The first and second hinge units are coupled so that the rotational center axes thereof orthogonally intersect each other.Type: GrantFiled: April 10, 2003Date of Patent: January 2, 2007Assignees: NEC Corporation, Mitsubishi Steel Mfg., Co., Ltd.Inventors: Masatomo Mizuta, Shinji Ikeuchi, Mitsuru Sendouda, Sakae Higano, Hitoshi Sato, Minoru Ohiraki
