A hand-portable electronic device 10 comprising: a first body part 11; a
second body part 12 rotatably connected to the first body part, the
second body part comprising a camera assembly 14 having an imaging axis
15 and an imaging window 16; and a slidable cover 13, the first and
second body parts being rotatable with respect to each other about a
rotation axis 17, the camera assembly being configured such that the
imaging axis is orthogonal to the rotation axis, the slidable cover being
adapted to slide between: i) a first position in which the first and
second body parts are unlocked and are thereby able to rotate relative to
one another; and ii) a second position in which the first and second body
parts are locked by engagement of the slidable cover therebetween,
relative rotation of the first and second body parts being thereby
prevented, and in which the slidable cover covers the imaging window.
