Abstract: A battery compartment for a device having a housing is provided. The battery compartment pivots around an axis that is generally parallel with a wall of housing. The battery compartment is generally an elongated wedge or sector shape with an elongated pivoting axis extending along the apex of the wedge. One planar side of the wedge becomes a portion of the wall of the housing as the battery compartment is pivoted about the elongated axis into a closed position. This planar side becomes a door into the housing that is opened or closed as the battery compartment is pivoted around its pivoting axis. As the battery compartment is pivoted around its pivoting axis, the battery compartment rotates out and away from the plane that previously encompassed the wall of the device so that access to the batteries may be had. The battery compartment encloses the batteries and segregates them from the other components in the housing.
