Patent number: 7577346Abstract: An image sensing module. A movable frame is disposed in and moves with respect to a fixed base. A support base is disposed in the movable frame and moves with respect to the fixed base. An image sensing unit is fixed to the support base. A first guiding mechanism combines the movable frame with the fixed base and moves with respect to the fixed base along a first direction, moving the support base with respect to the fixed base along the first direction. A first coil is disposed on the support base. A first magnet is disposed on the fixed base and opposes the first coil. A first Hall member is disposed on the support base and beside the first coil. When the first coil is energized by a voltage, a magnetic force is generated by the first coil and first magnet, moving the movable frame along the first direction.Type: GrantFiled: April 4, 2006Date of Patent: August 18, 2009Assignee: Asia Optical Co., Inc.Inventors: Jian-Chao Liao, Ching-Jung Tsai, Wen-Hung Hsieh

Patent number: 7493029Abstract: A camera module comprises a base, a lens joined to the base, a frame movably disposed on the base, an image detecting unit fixed to the frame and moving on the base via the frame, and a solenoid having a post moving between a first position and a second position. When the image detecting unit moves on the base via the frame, the post is in the first position and has no contact with the image detecting unit. When the image detecting unit moves on the base not via the frame, the post is in the second position and abuts the image detecting unit to position the image detecting unit.Type: GrantFiled: March 30, 2006Date of Patent: February 17, 2009Assignee: Asia Optical Co., Inc.Inventors: Jian-Chao Liao, Yao-Ching Huang

Patent number: 7315015Abstract: An image detecting module. The image detecting module comprises a base, a seat movably disposed on the base, an image detecting unit disposed on the seat, a first guide member by which the seat is joined to the base, moving relative to the base in a first direction, a first coil disposed on either the base or the seat, a first magnet disposed on either the base or the seat and opposite to the first coil, and a first Hall element disposed on either the base or the seat and adjacent to the first coil. A magnetic force is generated between the first coil and the first magnet by providing a voltage to the first coil, thereby moving the seat in the first direction along the first guide element.Type: GrantFiled: June 6, 2007Date of Patent: January 1, 2008Assignee: Asia Optical Co., Inc.Inventors: Wen-Hung Hsieh, Jian-Chao Liao, Ching-Jung Tsai
