ABSTRACT A crime prevention display device is disclosed which. includes a casing (21) provided therein with a chuck mechanism (20) for gripping a wire (W) inserted therethrough, a crime prevention alarm circuit (3) connected to the casing and a load detection means (40, 66, 25) for detecting a variation in load applied from an exhibit to the device. The load detection means (40) detects that removal of the exhibit held on the display device causes the device to be unloaded, so that the crime prevention alarm circuit (3) generates an alarm, leading to warning of the abnormality. Also, the crime prevention alarm circuit (3) generates an alarm sound, which is then collected by a sound wave receiver, followed by inputting of the alarm sound to a centralized control equipment (13), so that it may positively exhibit a crime prevention alarm function without causing any malfunction.
