DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate passing system implemented at an entrance of a library or the like.

[0002]

2. Description of the Related Art In libraries and the like, gates are provided at entrances and exits, for example, the number of visitors is counted at the entrance side, and illegal exiting of books is prevented at the exit side. As shown in FIG. 4, a passage 21 on the inlet side and a passage 22 on the outlet side are separately provided,
22 are equipped with flappers 23 and 24 that can be opened and closed manually, and a device for detecting unauthorized entry of books 25 on the inside of the passage 22 on the exit side.
The opening and closing of the flapper 24 on the exit side is controlled by the output of the unauthorized out-of-band detection device 25.

The flappers 23 and 24 are normally closed. To enter the building, the flapper 23 installed in the passage 21 on the entrance side is pushed by hand or upper body, and at this time the number of visitors Count.

When leaving, the flapper of the passage 22 on the exit side
Press 24 as you did when entering the library. At this time, the improper out-of-band detection device 25 reads the presence / absence of a signal from the tuttle tape attached to the book held by the exit person. This tuttle tape replaces the distinction between lending and returning books with a signal.For example, a signal attached to the tape affixed to the returned book is added to the tape, and the tape affixed to the book that has been borrowed is The signal is erased. If a signal is output from the tape of the book held by the person leaving the library and the lending procedure has not been performed by the unauthorized band detection device 25, the flapper 24 will Is closed to close the aisle and prevent exit.

[0005]

Conventionally, since the entrance and the exit are provided separately from each other, not only the installation space is required, but also a gate having a low probability of simultaneously using the entrance and the exit, such as a library. Then, the usage efficiency is not good.

Further, since the flapper provided at the gate is in a normally closed state, it must be pressed by hand or the like every time when going in and out, and it is troublesome. On the other hand, it is not always necessary to close the gate, so that users of facilities such as libraries can be given a closed impression, leading to a reduced image.

An object of the present invention is to eliminate the disadvantages of the prior art, reduce the space required for entrances and exits of facilities such as libraries, improve the use efficiency of gates, and give the entrance an open impression and facilitate entry. An object of the present invention is to provide a gate passing system that can surely prevent unauthorized exit at the exit.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention firstly provides a gate having a plurality of passages, which serve as an inlet and an outlet and which can pass in opposite directions, are arranged side by side. One flapper, whose end is rotatably mounted in the horizontal direction, is set to the storage position at a position separating adjacent passages, and is rotated from this storage position to select one of the adjacent passages on both sides. The flapper is provided as a common one in the two passages so as to be closed, and this flapper is separated from the fraudulent bandage detection device installed at the gate by a predetermined distance in the traveling direction, and the output of this fraudulent bandage detection device is rotated from the storage position as described above. Movement, so that one of two adjacent passages is selected and closed, secondly, the flapper is normally opened for passage in either direction, thirdly,
If there is a person who is passing the passage in the normally open direction,
The gist of the present invention is that even if there is a person who attempts to illegally pass through the same passage in the opposite direction at the same time, it is not closed.

According to the first aspect of the present invention, the passage provided at the entrance and exit serves as both the entrance and the exit, so that the installation space can be reduced, and the flapper can be used commonly for the two passages. Since the passage on the side of the person attempting to pass illegally is detected and selected and the side is closed, the use efficiency of the flapper is good.

[0010] In addition to this, the flapper is located in the gate in the advancing direction of the illegal out-of-band detection device, and even if the flapper is closed slowly for safety after the unauthorized out-of-book detection device detects the unauthorized removal of a book. When the exiting person arrives at the installation position of the flapper, the exiting member is disposed with a distance only for closing, so that the exiting person can be reliably prevented.

According to the second aspect of the present invention, in addition to the above-mentioned operation, for example, in a direction in which a passage is used as an entrance, the flapper is normally opened so that entrance to the library like a library can be performed. Facilities that do not need to be regulated not only do not needlessly operate the flapper, but also can easily enter because the entrance can be opened.

According to the third aspect of the present invention, in addition to the above-described operation, when the flapper is normally opened in a direction in which the passage is used as an entrance, a visitor passes through the passage. In this case, the flapper does not close even if an unauthorized person tries to pass through the same passage from the opposite direction, so that the safety of visitors can be ensured.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a gate passing system according to the present invention. A plurality of fraudulent band detection devices 1 for detecting fraudulent banding of books are installed on the building side of the entrance and exit as appropriate with a width that allows a person to pass through, and a plurality of passages 2 are formed.

The passage 2 serves both as an entrance and an exit, and has a width of, for example, 90 cm or more so that not only a healthy person can pass but also a wheelchair disabled person.

As in the prior art, the illegal out-of-band detecting device 1 detects the presence or absence of a signal from a tuttle tape attached to a book held by a person leaving the library, and is arranged on a partition member formed in a partition shape. Established. Tuttle tape replaces the distinction between lending and returning a book with a signal.For example, a signal attached to a tape attached to a returned book is a signal, and a tape attached to a book that has been borrowed is a signal. Is erased.

A pole 3 made of plastic is erected outside the hall of the fraudulent out-of-office detection device 1, and a hollow column 5 having a flapper 4 and an infrared beam hole 8 attached thereto at a predetermined distance from the pole 3 is provided. Fences 7 provided with reflection plates 6 at appropriate intervals are alternately arranged, and a plastic chain 9 is bridged between the pole 3 and the support 5 and the fences 7.

The flapper 4 is formed of a horizontally long vertical plate, and a forward / reverse rotation motor 10 is disposed inside the column 5 as a driving mechanism of the flapper 4, and the rotating shaft of the motor 10 is connected to the flapper 4 via a brake 11. Connect to the rotating shaft. As a result, the end of the flapper 4 is freely rotatable in the horizontal direction with respect to the support column, and the position separating the two adjacent passages 2 becomes the storage position. Can be selectively rotated so as to shut off. In addition, a position detecting device 12 for detecting the rotational position of the flapper 4 is attached to an appropriate position such as the end of the flapper 4 or the rotating shaft of the motor 10.

The infrared beam hole 8 and the reflection plate 6 are disposed at opposing positions, and a photoelectric sensor 13 for detecting the reflected light from the reflection plate 6 is disposed in the column 5, so that illegal out-of-bounds of the book is detected. A warning light 14, a sound or buzzer generator 15, and a counter 17 for counting the number of visitors are installed at appropriate places such as the upper part of the support 5 as alarms that are sometimes activated.

And a control device for controlling the operating member.
3, the detection signals from the unauthorized out-of-band detection device 1, the position detection device 12, and the photoelectric sensor 13 are introduced into the control device 16 as shown in the control block diagram of FIG.
The drive signal from the control device 16 was introduced to the motor 10 via the triac 18, and the operation signal from the control device 16 was introduced to the warning light 14, sound and buzzer generator 15 and the counter 17.

Next, the operation will be described. The flapper 4 is always located parallel to the passage 2 and is in a stored state, and the passage 2 is open. In addition, infrared rays are always emitted from the infrared beam hole 8 to the reflection plate 6.

When there is a person who uses the passage 2 as an entrance and enters the building, the infrared rays are cut off when passing between the infrared beam hole 8 and the reflecting plate 6.
The infrared rays reflected at the are cut off sequentially from the outside of the hall toward the inside of the hall. Therefore, the direction of the interruption and the direction of the interruption from the outside of the hall to the inside of the hall are detected by the photoelectric sensor 13, and the control device 16 determines that there is one occupant and outputs it to the counter 17 to count the number of occupants.

At this time, since the flapper 4 is open, the occupant may proceed along the passage 2 and enter the premises.

After entering the library, if you borrow a book and carry out the lending procedure, for example, the signal of the tuttle tape attached to the book will be erased. If it passes outside, no signal is input to the illegal out-of-band detection device 1 from the tuttle tape, so that the unauthorized out-of-band detection device 1 does not operate. Therefore, since the passage 2 is opened while the flapper 4 is also in the stored state, the flapper 4 can exit as it is.

When the exiting person passes through the passage 2, as in the case of entrance, the exiting person crosses the infrared ray emitted from the infrared beam hole 8 to the reflecting plate 6, and the reflection of the infrared ray is blocked. In this case, the reflection of infrared rays is sequentially interrupted in the direction opposite to the direction when entering the building.

If the user tries to illegally take out the book without performing the lending procedure, the signal on the tuttle tape attached to the book remains unerased. Is detected by the illegal out-of-band detection device 1 and the detection signal is transmitted to the control device 16.
Is input to

As a result, the output from the controller 16
10 rotates. In this case, the position detection device 12 detects that the flapper 4 is in the retracted position, and this position detection signal is input to the control device 16, while the detection signal detected by the unauthorized out-of-band detection device 1 Determines the path 2 in which the illegal exit is about to be performed.
From 16, a rotation drive signal is output to the drive circuit of the motor 10 in the direction of the passage 2 in which the illegal exit detected by the unauthorized exit detection device 1 is about to be performed.

As a result, the flapper 4 selects one of the two passages 2 adjacent to the flapper 4 and pivots toward the passage 2 to close the passage 2 and prevent retreat. At the same time, the warning light 14 and the sound or buzzer generator 15 are activated by the output from the control device 16 in the same manner, and the warning light 14 lights or blinks,
A buzzer is emitted from the generator 15, and a sound is issued to notify the illegal exit.

The flapper 4 is connected to two adjacent passages 2
However, since there are almost no cases where illegally exited persons pass through two passages 2 at the same time,
There is no inconvenience that unauthorized exit cannot be prevented. In the case where an illegal exit is to be performed in the passage 2 blocked by the above and the adjacent passage 2 defined by the flapper 4,
Similarly, the flapper 4 rotates in the direction of the passage 2 in a direction opposite to that in the above case, and prevents the flapper 4 from retreating.

Further, since the passage 2 serves both as an entrance and an exit, a person entering and leaving the building may pass through one passage 2 at the same time. In this case, there is an output from the improper out-of-office detection device 1 when the exiting person unfairly books the book, but when the detection signal indicating the presence of the intruder from the photoelectric sensor 13 is output at the same time, the control device 16 Not output to motor 10.

Thus, the flapper 4 is not closed by a person who leaves the book illegally, and entry of the person is not prevented. Also in this case, the warning light 14 and the sound or buzzer generator 15 operate.

Furthermore, even if it takes time to slowly rotate the flapper 4 and close it for safety, especially for a disabled person using a wheelchair, the flapper 4 and the unauthorized out-of-band detection device 1 can be connected to each other. Since it is installed at a predetermined distance, it takes time for the exit person to pass by the fraudulent out-of-band detection device 1 and reach the position of the flapper 4, and pass through the flapper 4 before closing. Can be prevented.

At this time, since the plastic chain 9 is stretched between the fraudulent out-of-band detecting device 1 and the flapper 4, it is possible to prevent the fraudulent withdrawal from between.

Further, the operating flapper 4 is, for example, 3K.
If the user collides with a strong force of
The brake 11 that controls the clutch automatically comes off to reduce the impact,
Ensuring user safety.

[0034]

As described above, according to the gate passage system of the present invention, the passage provided at the entrance and exit serves both as the entrance and the exit, so that the installation space can be reduced, and the flapper is shared for the two passages. As a matter of course, the passage on the side of a person who intends to pass illegally is detected and selected and the side is closed, so that the use efficiency of the flapper is good.

In addition to this, the flapper is located in the gate in the direction of passage with respect to the unauthorized passage detection device, and even if the flapper is slowly closed for safety after the unauthorized passage detection device detects the unauthorized removal of a book. When the exiting person arrives at the installation position of the flapper, the exiting person can be surely prevented from exiting by arranging the flapper so that it is closed only by a distance.

Also, for example, in the direction in which the passage is used as the entrance, the flapper is normally opened,
In a facility such as a library that does not need to regulate entry, not only does it not needlessly operate the flapper, but the entrance can be opened because the entrance is open, making it possible to realize an open library.

Further, for example, when the flapper is normally opened in the direction in which the passage is used as the entrance,
When a visitor is passing through the aisle, the flapper does not close even if an unauthorized person attempts to pass through the same passage from the opposite direction, so that the safety of the visitor can be ensured.
