Patent number: 8493638Abstract: Disclosed are a scanner capable of adjusting the focus distance and an image forming apparatus having the same. The scanner may include a focus adjustment structure that comes into an interfering contact with a scanning unit as the scanning unit moves along a scanning path so as to cause a movement of the scanning unit in the direction perpendicular to the scanning path toward and away from the document to be scanned. With such configuration the focus adjustment can be realized using the scanning movement of the scanning unit along the scanning path.Type: GrantFiled: January 8, 2010Date of Patent: July 23, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Dong-Gyoo Lee

Publication number: 20060288533Abstract: A hinge structure is provided. The hinge structure uses a magnetic force and includes a shaft, provided at one side of a cover and rotatably supported by a body. At least one permanent magnet having a magnetic field perpendicular to the longitudinal direction of the shaft is fixed to the shaft. A shaft operation portion is provided in the cover for rotating the shaft by about 180 degrees and rotating between a first position and a second position by a user's operation. At least one electromagnet is arranged at a position corresponding to the permanent magnet of the body, thereby aiding the opening and closing of the cover and absorbing any impact using a magnetic force between the permanent magnet and the electromagnet.Type: ApplicationFiled: June 27, 2006Publication date: December 28, 2006Inventor: Dong-gyoo Lee
