Abstract
An antitheft system embodying the invention comprises an alarm unit 2 attached to a commodity for producing an alarm on receiving a detection signal or an alarm activating signal while stopping the alarm on receiving an alarm stopping signal, and a signal generator provided on a cashier's counter for producing alarm activating signals and alarm stopping signals alternately. When the commodity is handed by the customer to the clerk at the cashier's counter, with the alarm unit 2 attached to the commodity, the alarm unit 2 intermittently produces an alarm on receiving alarm activating signals and alarm stopping signals alternately, thereby enabling the clerk to reliably recognize that the alarm unit 2 is attached to the commodity. When the clerk thereafter removes the alarm unit 2 from the commodity, the production of alarm is forcibly ceased.
