Has been done.

Next, the processing operation in the control device 18 when the vehicle is going to pass through the inspection gate will be described with reference to the flowchart shown in FIG. Now, when a certain attendant tries to pass through the inspection gate and operates the door switch 7 of the facility entrance / exit 2B in step S1 of FIG. 6, step S1 is performed.
2, the electric motor 6 operates and the door 5B is operated in step S3.
Opens. Then, the employee can enter the inspection passage 3 in step S4, whereupon the electric motor 6 is activated again and the door 5B is closed in step S5. After that, when the attendant walks toward the door 5A, the belongings inspection means including various inspection devices arranged in the inspection passage 3 is activated to inspect the belongings.

First, in step S6, the metal detector 8 installed on the wall surface operates. This metal detector 8 has a detector 1
One transmitter coil and two receiver coils are arranged,
Since the voltage is induced by receiving high-frequency magnetic field lines from the transmitting coil at the receiving coil, when an iron article, which is a ferromagnetic material, approaches or passes in the vicinity, the magnetism at that location increases, causing induced voltage fluctuations. Can be detected.
When the control device 18 detects a metal object, the control device 18 gives a command to the alarm device 19 to sound an alarm to notify the alarm and check the belongings.

If there is no detection by the metal detector 8, the radio sensor 9 attached to the ceiling operates in step S7 in the inspection passage 3 to detect the presence or absence of a radio tag using microwaves. . A radio wave tag is attached to valuables or secrets in advance, and the radio wave sensor 9 detects that the attendant has this, and the control device 18 can sound an alarm device 19 to notify. .

Next, the attendance checker is managed by the attendance checker. In step S8, the weight is measured by the weight scale mat 10 installed on the floor in the inspection passage 3, and when the weight is equal to or greater than the preset value, the control device 18 causes the alarm device 19 to ring, The attendees are managed so that two people do not pass through the inspection passage 3 at the same time, and the luggage is checked.

In step S9, the photoelectric sensor 11 installed on the wall surface in the inspection passage 3 is used to inspect the attendants. Since the photoelectric sensor 11 is arranged as shown in FIG. 5, the photoelectric sensor 1 in row A and column 1 or row A and column 2 is used.
If 1 is sensitive and the photoelectric sensor in the A row 3 column or the A row 4 column is sensitive, and two non-consecutive points in the B row and C row are sensitive, etc., 2 or more people in the inspection passage 3 I can judge that I was there. In addition, the photoelectric sensors 11 in the rows B and C are 3
If you feel more than the points, you can judge that you are carrying a large baggage. Similarly, the photoelectric sensor 11 can also be used to check whether the attendant has an unnatural posture while standing sideways or biting while standing in the traveling direction. The detection timing of the photoelectric sensor 11 is read when the weight scale mat 10 is stable.

Further, in step S10, the attendants are identified by passing an ID card through the personal identification device 12 installed on the wall surface in the inspection passage 3 or by inputting the recitation number using the recitation number input device 13. If the user makes a mistake in the input operation, the return button switch 16 installed on the same wall can be operated to start over (step S12). Data such as weight is registered in advance in the personal identification device 12 for each individual. Therefore, by comparing the personal data obtained by supplementing the registered value with the variation value and the measurement result by the weight scale mat 10, It is possible to determine that someone else's card was used or that the wrong recitation number was used.

In any case, when the alarm device 19 sounds (step S11), the abnormality is displayed on the display panel 1.
4, the state of the inspection passage 3 can be monitored by the camera 15 from a distant place. Further, in the case where a worker who leaves and works in the inspection passage 3 is trapped due to an abnormality, it is possible to deal with it by contacting a guard or the like through the intercom 17 shown in FIG. When the inspection devices determine that there is no abnormality, the control device 18 operates the electric motor 6 to open the door 5A (step S1).
3) Allowing the attendants to pass through (step S14), and then closing the door 5A to prepare for the next attendant (step S16).

In this embodiment, I is used as the personal identification.
Although a personal identification device using a D card or a personal identification number has been illustrated, the same effect can be obtained by performing personal identification by fingerprint collation, voiceprint collation, handwriting collation, or the like.
