Abstract

The present invention is to provide a weapon detector system that does not give an uncomfortable feeling to a general messenger passing through an entrance.

The weapon detector system of the present invention comprises:

a detecting gate 2, which is placed on the inside of an entrance 1;

a central processing unit 4 connected by wire with transmitter coils 3a and receiver coils 3b of the detecting gate 2; and

an image receiving device 6, a warning indication lamp 7 and a photographing device 8 that are wirelessly controlled by the central processing unit 4, in characterized that the detecting gate 2 comprises a pair of side panels 9a and 9b without an upper panel which is connected the side panels each other, wherein one of said side panels contains the transmitter coils 3a and the other side panel contains the receiver coils 3b, the side panel 9a containing the transmitter coils 3a and the side panel 9b containing the receiver coils 3b stands on both sides of the entrance to face each other, and the insulating material 11 is situated on a suitable position of a metallic frame 12 surrounding the entrance 1 for the sake of preventing a scattering and vortex phenomenon.

Claims

1. A weapon detector system that does not give an uncomfortable feeling to a general messenger passing through an entrance comprises:

a detecting gate 2 which is placed on the inside of an entrance 1;

a central processing unit 4 connected by wire with transmitter coils 3a and receiver coils 3b of the detecting gate 2; and

an image-receiving device 6, a warning indication lamp 7 and a photographing device 8 that are wirelessly controlled by the central processing unit 4, in characterized that

the detecting gate 2 comprises a pair of side panels 9a and 9b without an upper panel which is connected the side panels each other, wherein one of side panels contains the transmitter coils 3a and the other side panel contains the receiver coils 3b, the side panel 9a containing the transmitter coils 3a and the side panel 9b containing the receiver coils 3b stands on both sides of the passage facing each other.

2. A detector system according to claim 1, wherein an insulating material 11 is situated on a suitable position of a metallic frame 12 surrounding the entrance 1 for the sake of preventing a scattering and vortex phenomenon of an electromagnetic field caused by the metallic frame 12, when the entrance 1 is closed.

3. A detector system according to claim 1, wherein the insulating material 11 is situated on 4˜

8 places of the metallic frame 12 surrounding the entrance 1.
