Publication number: 20080174127Abstract: Disclosed herein is an opening and closing apparatus for mobile phones. The apparatus includes an electromagnet which is installed at a predetermined position in a main body, with a permanent magnet being provided in the electromagnet. A metal piece is installed at a predetermined position in a display body, which is foldably coupled to the main body, and generates attractive force between the metal piece and the permanent magnet of the electromagnet. The electromagnet generates magnetic force to offset the attractive force between the permanent magnet and the metal piece when external electricity is applied to the electromagnet. The apparatus also includes a coil spring which elastically biases the display body to open the display body when external electricity is applied to the electromagnet.Type: ApplicationFiled: January 22, 2008Publication date: July 24, 2008Applicant: SAMSUNG ELECTRO-MECHANICS CO., LTD.Inventors: Seong Geun Kim, Oh Soo Kwon
