ABSTRACT:
Removal of a suitcase from the owner's hand causes a plug to be separated from a jack to supply power to an alarm circuit which provides audible and visible alarms. Alternatively, the alarm circuit is actuated by unauthorized movement of the suitcase from the position in which the user left it. For convenience, the suitcase includes a built in radio, an umbrella mounting and an external source of illumination.
