Patent ID: 8199487

Claim:
An apparatus comprising: a display portion having a display edge portion; a housing having a housing edge portion; a first mechanism configured to enable a first constrained relative motion between at least the display edge portion and the housing edge portion in at least a first direction to change a configuration of the apparatus from a first compact configuration, in which the display edge portion and housing edge portion have at least a partial overlap in a second direction, to a second less compact configuration in which the display edge portion and housing edge portion are offset in the first direction removing said at least partial overlap in the second direction; second mechanism configured to enable a second constrained relative motion between the display portion and the housing in at least the second direction different to the first direction to change the configuration of the apparatus from the second configuration to a third extended configuration in which the display edge portion and the housing edge portion are offset, compared to the second configuration, in at least the second direction, where the second mechanism is operable to enable the second constrained relative motion only after the display edge portion and the housing edge portion at least partially obtain the second less compact configuration.
