Patent 7161093 was granted and assigned to Inventec on January, 2007 by the United States Patent and Trademark Office.
An aligning gear for an electronic device including a circuit board having at least a first fixing section and a housing having at least a second fixing section is disclosed. The aligning gear includes a first limiting member and a second limiting member, both of which are installed on the housing. The first limiting member limits the circuit board to move along a first direction only, while the second limiting member limits the circuit board to move along a second direction perpendicular to the first direction, so as to make the first fixing section of the circuit board inosculate with the second fixing section of the housing along the first direction and the second direction respectively. Thereby, the circuit board is adjusted to a position where the circuit board is to be fixed to, so as to fix the circuit board on the housing and finish the subsequent fastening action.
