Patent ID: 7834739

Claim:
A baggage management gate comprising: a first reading device that reads personal information of a first person who passes through a passage to enter to a management region in which baggage is managed; a second reading device that reads personal information of a second person who passes through the passage to exit from the management region in which the baggage is managed; a detecting device that generates an alternating magnetic field in the passage and detects a variation in the alternating magnetic field when magnetization reversal occurs in a magnetic material due to a large Barkhausen effect in the alternating magnetic field; a determining unit that determines as to whether the first person is allowed to pass through the passage, based on information indicating the detection signal by the detecting device and information obtained from the first reading device, and the determining unit that determines as to whether the second person is allowed to pass through the passage, based on information indicating the detection signal by the detecting device and information obtained from the second reading device; a first opening and closing device for the first person, that opens or closes the passage based on a result as to the first person determined by the determining unit; a second opening and closing device for the second person, that opens or closes the passage based on a result as to the second person determined by the determining unit; and wherein in order away from the region in which the baggage is managed, (i) the first reading device, (ii) the second opening and closing device, (iii) the detecting device for both the first person and the second person, (iv) the first opening and closing device, and (v) the second reading device are arranged in an entrance direction from the passage to the management region in which the baggage is managed.
