PURPOSE: A device for preventing articles from being lost is provided to equip detectors in detection-targeted objects such as notebooks and bags and to equip controllers on users or detecting subjects, so as to previously prevent precious articles from being lost. CONSTITUTION: A first sensor(11) of a detector(1) senses a vibration of a detection-targeted article, and outputs an electrical signal. A first communicator(12) transceives data with a controller(2) through an antenna(ANT1). A first signal processor(13) processes the electrical signal and synthesizes the electrical signal with a preset inherent code, then transmits the synthesized signal to the controller. The first signal processor processes an alarm signal generated from the controller and outputs the alarm signal to a backside. A first alarming unit(14) displays an alarm with a vibration alarm, a light emitting alarm, and an alarming sound according to the alarm signal. The controller equipped in a detecting subject detects movements of the article, and compares presently-detected information with movement state information of the detector. If differences between the two information are bigger than a setup value, the controller drives a self alarming unit and transmits the alarm signal from the detector.
