Patent number: 8605418Abstract: A two-axis hinge unit is provided with a first rotating shaft that rotates so as to open in the vertical direction from a folded state with a first casing and a second casing overlapping and a second rotating shaft that rotates so as to open in the horizontal direction from a folded state with the first casing and the second casing overlapping, and is provided with a restriction member positioned between the first rotating shaft and the second rotating shaft that, when one of the rotating shafts is in a predetermined rotational position, is pressed by this one rotating shaft and engages with the other rotating shaft, thereby restricting rotation of that other rotating shaft.Type: GrantFiled: September 12, 2012Date of Patent: December 10, 2013Assignee: NEC CorporationInventors: Wakato Hayashi, Yuuichi Oota, Satoshi Tanaka, Hirokazu Nagae, Yusuke Yamamoto, Nobuyoshi Ooba, Tetsuo Ito, Noriyuki Iwama

Patent number: 7986985Abstract: A cellular phone device has an operation-unit casing, a sliding casing which is coupled to the operation-unit casing with the front face of the sliding casing facing the rear face of the operation-unit casing, and which slides with respect to the operation-unit casing in a direction parallel to the rear face of the operation-unit casing, and a direction input device provided on the rear face of the operation-unit casing. The sliding casing slides with respect to the operation-unit casing between a state where the direction input device is covered by the sliding casing and a state where a covering of the direction input device by the sliding casing is released.Type: GrantFiled: April 16, 2008Date of Patent: July 26, 2011Assignee: Casio Hitachi Mobile Communications Co., Ltd.Inventors: Hirokazu Niitsu, Masaki Uesugi, Yuuichi Oota, Motoyuki Tanaka
