Abstract
A portable electronic device includes first and second housing portions pivotal about corresponding pivot axes. A biasing member urges a first cam surface of the first housing portion into engagement with a second cam surface of the second housing portion. The biasing member also urges indexing members of the first and second housing portions into engagement to maintain synchronization of the housing portions during rotation, wherein the first and second housing portions are configured in a fixed angular orientation when the first cam surface is engaged with the second cam surface.
