Detailed Description

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the description, an orthogonal coordinate system including mutually orthogonal X, Y, and Z axes is used as appropriate.

First embodiment

Fig. 1 is a perspective view of a safety door 1 according to a first embodiment. The security gate 1 authenticates a person who enters and exits between a public space and a private space such as a commercial building and an office building, and restricts the entrance and exit of the person. The dedicated space is a store in a retail store where the commercial building is resident as a tenant, a reception desk of an enterprise where the office building is resident as a tenant, or the like. In addition, the public spaces are corridors, stairways, elevator cars, lobbies, etc. The safety door 1 is provided as a barrier (feng) or the like for separating a private space from a public space. In the following embodiments, the-Y side of the security gate 1 is a public space, and the + Y side is a private space.

The security gate 1 has 1 set of gate units 10A, 10B. The gate unit 10A has a side wall 10 parallel to the YZ plane, and a shutter 20 that rotates in an undulation (japanese: undulation) with respect to the side wall 10.

The side wall 10 defines a passage between the private space and the public space. The side wall 10 includes a metal frame 11, transparent plates 12 and 13 provided in the frame 11, a sensor 14 provided in the frame 11, a reader 15, and the like.

The frame 11 has: three parts, namely, a fixing part 11a which is fixed on the ground with the length direction as the Y-axis direction, a support column 11b which is arranged on the fixing part 11a and has the Z-axis direction as the length direction, and a guide 11c which is supported above the fixing part 11a by the support column 11b with the Y-axis direction as the length direction. The fixing portion 11a, the support column 11b, and the guide 11c constituting the frame 11 have hollow members therein, and the respective internal spaces communicate with each other.

The transparent plates 12 and 13 are rectangular plate-like members whose longitudinal direction is the Y-axis direction. The transparent plates 12 and 13 are made of acrylic, glass, or the like, and have light transmittance with respect to visible light. The transparent plates 12 and 13 are supported by the fixing portion 11a, the support column 11b, and the guide 11c constituting the frame 11 in a state parallel to the YZ plane.

the sensor 14 detects a person located in the vicinity of the door unit 10A, and outputs a signal corresponding to the result of the detection. The sensor 14 is provided at the-Y-side end of the guide 11 c.

The reader 15 reads a two-dimensional code such as a barcode provided on a pass or a card, or authentication information from an ID card, and outputs a signal indicating the read authentication information. The reading device 15 is provided at the-Y-side end of the guide 11c in a state where a scanner for reading the authentication information is exposed.

The baffle 20 is a square plate-like member. The shutter 20 is made of acrylic, glass, or the like, as with the transparent plates 12 and 13, and has transmissivity with respect to visible light. The flap 20 is supported by a drive mechanism 80 (see fig. 7) provided on the support column 11b of the frame 11 so as to be swingable up and down about the support column 11 b. The drive mechanism 80 includes a motor, a link mechanism that transmits power from the motor to the barrier 20, and the like.

fig. 2 is a front view of the baffle plate 20. As shown in fig. 2, a first display device 50 is provided on the barrier 20. Fig. 3 is a top view of the display device 50. As shown in fig. 3, the display device 50 displays an image of a predetermined figure or character by lighting a plurality of light emitting elements 60 arranged so as to display the figure or character. In the present embodiment, the light emitting element 60 is configured to display an image of an X-shaped pattern indicating no-pass.

Fig. 4 is a view showing a side surface of the display device 50 on the-X side. Fig. 5 is a view showing a side surface of the display device 50 on the-Z side. As shown in fig. 4 and 5, the display device 50 includes transparent films 51 and 52, a conductor layer 53, an intermediate resin 55, and a plurality of light-emitting elements 60.

The transparent films 51 and 52 are square shaped films. The transparent films 51 and 52 have a thickness of about 50 to 300 μm and have a transmittance to visible light. As the transparent films 51 and 52, polyethylene terephthalate (PET), polyethylene naphthalate (PEN), Polycarbonate (PC), polyethylene succinate (PES), ARTON (japanese: ア ー ト ン), acrylic resin, or the like can be used.

a conductor layer 53 is formed on the upper surface of the transparent film 51. The conductor layer 53 is formed of a transparent conductor such as a mesh pattern having light transmittance or ito (indium Tin oxide). As shown in fig. 3, the conductor layer 53 is formed of a plurality of conductor patterns 101 to 113 connected to the anode electrode or the cathode electrode of each light-emitting element 60. The plurality of conductor patterns 101 to 113 are shaped into rectangles having a longitudinal direction in the X-axis direction and are arranged at equal intervals in the Z-axis direction. The conductor patterns 101, 107, and 113 are guided to extend above the + X-side end of the transparent film 51. In the display device 50, as shown in fig. 5, the dimension of the transparent film 52 in the X axis direction is shorter than the dimension of the transparent film 51 in the X axis direction, and the + X side end of the conductor layer 53 formed on the transparent film 51 is exposed. Therefore, the conductor patterns 101, 107, and 113 are exposed above the-X-side end of the transparent film 51. Although the rectangular conductor patterns 101 to 113 are shown in fig. 3, the rectangular conductor patterns 101 to 113 may have shapes other than a rectangle according to the arrangement of the light emitting elements 60.

In the display device 50, dc power having a voltage of, for example, about 15V is supplied between the conductor pattern 107 and the conductor patterns 101 and 113 according to the type and number of the light emitting elements 60, the operating voltage, and the like.

A plurality of light emitting elements 60 are disposed on the upper surface of the conductor layer 53. The light emitting element 60 is a square LED having a side length of about 0.3mm, as shown in fig. 3. A cathode and an anode are formed on one surface (+ Y side surface) of the light-emitting element 60. The light emitting element 60 emits light on both the-Y side surface and the + Y side surface. The rated current of the light emitting element 60 is about 50 mA. When the light emitting element 60 is a transparent film LED having a large thermal resistance, the rated current is about 10 mA.

The light-emitting element 60 configured as described above is disposed across any two of the conductor patterns 101 to 113 constituting the conductor layer 53. The light emitting elements 60 arranged in the same one of the conductor patterns 101 to 113 are connected in parallel. The light emitting elements 60 arranged in different ones of the conductor patterns 101 to 107 are connected in series. Similarly, the light emitting elements 60 arranged in different ones of the conductor patterns 107 to 113 are connected in series.

As shown in fig. 4 and 5, the intermediate resin 55 is disposed between the transparent films 51 and 52. The resin layer 24 has transmissivity with respect to visible light. The intermediate resin 55 is a thermoplastic resin, such as a thermoplastic elastomer. As the elastomer used for the intermediate resin 55, an acrylic elastomer, an olefin elastomer, a styrene elastomer, an ester elastomer, a urethane elastomer, and the like are considered.

The display device 50 configured as described above is bonded to the barrier 20 with a transparent adhesive. The display device 50 is made of a transparent member except for the light emitting element 60 having one side of 0.3 mm. Therefore, the barrier 20 looks substantially transparent even if the display device 50 is bonded thereto.

As shown in fig. 5, in the display device 50, a flexible cable 70 is connected to the conductor layer 53 exposed from the + X side of the transparent film 52. The flexible cable 70 includes a flexible base substrate 71, a conductor layer 75 formed on the base substrate 71, and a protective layer 72 covering the conductor layer 75. As shown in fig. 5, the conductor layer 75 is composed of three conductor patterns 751, 752, 753. The conductor patterns 751, 752, 753 are connected to the conductor patterns 101, 107, 113, respectively. As shown in fig. 2, the flexible cable 70 is laid inside the frame 11. The display device 50 is connected to a control device 30 described later by a flexible cable 70.

Fig. 6 is a side view of the door unit 10A. As shown in fig. 6, a controller 30 is disposed on a fixing portion 11a of a frame 11 constituting a door unit 10A. Fig. 7 is a diagram showing a hardware configuration of control device 30. As shown in fig. 7, the control device 30 is a computer having an arithmetic processing circuit 30a, a main storage unit 30b, an auxiliary storage unit 30c, an interface 30d, a bus 30e connecting these units, and the like.

The main memory unit 30b is constituted by a ram (random Access memory) or the like, and is used as a work area of the arithmetic processing circuit 30 a. The auxiliary storage unit 30c is constituted by a rom (read Only memory), a hard disk, and the like, and stores a program executed by the arithmetic processing circuit 30a, a processing result by the arithmetic processing circuit 30a, and the like.

The interface 30d includes an analog interface, a digital interface, a LAN interface, or the like. The sensor 14, the reading device 15, the display device 50, and the drive mechanism 80 are connected to the control device 30 via the interface 30 d.

The arithmetic processing circuit 30a controls the display device 50 and the driving mechanism 80 based on the outputs of the sensor 14 and the reading device 15.

Returning to fig. 1, the door unit 10B also has a side wall 10 parallel to the YZ plane and a shutter 20 that swings with respect to the side wall 10, similarly to the door unit 10A. As shown in fig. 1, the door units 10A and 10B are installed on the floor in a state where the side walls 10 are parallel to each other and the positions of the shutters 20 in the Y-axis direction are aligned.

The sensor 14, the reading device 15, the display device 50, and the drive mechanism 80 of the door unit 10B are connected to the control device 30 of the door unit 10A. Accordingly, the components of the gate units 10A and 10B are controlled by the control device 30. The controller 30 controls the drive mechanisms 80 of the door units 10A and 10B to rotate the shutters 20 from the state shown in fig. 1 to the state shown in fig. 8, thereby opening the shutters 20. Further, the controller 30 controls the driving mechanism 80 to rotate each shutter 20 from the state shown in fig. 8 to the state shown in fig. 1, thereby closing the shutter 20.

next, the operation of the safety door 1 configured as described above will be described. As a precondition, the flap 20 is closed as shown in fig. 1.

When the security gate 1 is powered on and activated, the control device 30 receives signals from the sensor 14 and the reading device 15. The control device 30 drives the display device 50 provided at each barrier 20 of the door units 10A, 10B when a person approaches the security gate 1 based on the signal from the sensor 14. Specifically, the driving is performed by supplying dc power having a voltage corresponding to the type, number, operating voltage, and the like of the light emitting elements 60 between the conductor pattern 752 and the conductor patterns 751 and 753 of the flexible cable 70. As a result, the light emitting element 60 of the display device 50 emits light, and an X-shaped image is displayed on each shutter 20 of the gate units 10A and 10B, as shown in fig. 9. The X-shaped graphic image displayed on the display device 50 can be visually recognized from both the-Y side and the + Y side of the barrier 20.

In this state, the control device 30 extracts the authentication information when the signal from the reader 15 includes the authentication information uniquely assigned to the ID card held by the person who wants to pass. Then, the person is authenticated based on the authentication information, and whether or not the passage is permitted is determined.

When the person who wants to pass is authenticated and it is determined that the person is permitted to pass, the control device 30 stops the driving of the display device 50 and opens the flapper 20 for a predetermined time via the driving mechanism 80. Thereby, the image of the X-shaped pattern displayed on the shutter 20 disappears, and the shutter 20 is opened for a certain period of time. This allows a person who wants to pass through the security gate 1. When a certain time elapses after a person who wants to pass passes through the emergency gate 1 or the barrier 20 is opened, the control device 30 controls the driving mechanism 80 to close the barrier 20.

When the person who wants to pass is not authenticated and it is determined that the person is not permitted to pass, control device 30 continues driving display device 50. Thereby, the X-shaped image continues to be displayed on the barrier 20.

As described above, in the safety door 1 of the present embodiment, the display device 50 is provided on the shutter 20. Therefore, the display device can be made larger than the conventional display device provided with the guide 11c and the like in fig. 1, and the visibility can be greatly improved. As a result, the safety of the baffle 20 can be ensured.

The display device 50 is made of a transparent member except for the light emitting element 60 having a side of about 0.3 mm. Therefore, even if the baffle 20 or the like is transparent, the design is not impaired. Further, since the display device can be increased in size, images such as various characters and graphics can be displayed. Thus, the degree of freedom of design can be improved.

In the first embodiment, when the safety door 1 cannot be passed through, an X-shaped image is displayed on the barrier 20. The present invention is not limited to this, and a circular graphic image may be displayed when the image can pass through the security gate 1.

By providing the barrier 20 with a display device 50 that displays an X-shaped image and a second display device 50 (not shown) that is transparent and displays a circular image in a superimposed manner, the circular image can be displayed when the security gate 1 is allowed to pass through. A display device displaying an image of a figure can be obtained by changing the arrangement of the light emitting elements 60 shown in fig. 3 from X-shape to circular shape. Specifically, referring to fig. 10, when the control device 30 authenticates a person who wants to pass and determines that the person is permitted to pass, the control device stops driving of the display device 50 and drives the display device displaying the image of the pattern, thereby stopping display of the image of the X-shaped pattern displayed on the barrier 20 and displaying the image of the circular pattern on the barrier 20.

A display device displaying a circular image can be superimposed and bonded on the display device 50 provided on the barrier 20. Further, the display device 50 may be bonded to one surface of the baffle 20, and a display device for displaying a circular image may be bonded to the other surface of the baffle 20. Since both the display device 50 and the display device displaying a circular image are transparent, they can be freely designed according to the situation.

The light emitting elements 60 shown in fig. 3 are arranged along the outline of the arrow-shaped pattern, whereby a third display device 50 (not shown) for displaying an image of the arrow-shaped pattern can be configured. By providing the third display device 50 together with the display device 50 and the second display device 50 on the flap 20, it is possible to display an image of an arrow-shaped figure indicating the passing direction when the flap 20 of the security gate 1 is opened. Specifically, when determining that the passage of the person who wants to pass is permitted, the control device 30 controls the drive mechanism 80 to open the barrier 20 and drives the third display device 50, thereby displaying an image of an arrow-shaped figure indicating the passage direction on the barrier 20 as shown in fig. 11. The third display device 50 may be bonded to the bezel 20 so as to overlap the first display device 50 and the second display device 50 provided on the bezel 20, or may be directly bonded to the bezel 20.

In the first embodiment, the display device 50 including one module including the light emitting element 60 is described. The display device is not limited to this, and may be configured by display devices 501, 502, and 503 as in the fourth display device 50C shown in fig. 12, and the display devices 501, 502, and 503 may include light emitting elements 60R, 60G, and 60B that emit light in red, green, and blue, respectively. The display devices 501, 502, 503 are bonded by a transparent adhesive. In the display device 50C, by selectively driving the display devices 501, 502, and 503, it is possible to combine three colors of light of red, green, and blue to display an image, and it is possible to display an image of a character or the like in white or an intermediate color.

Second embodiment

Hereinafter, the display of the second embodiment will be described. In addition, a fifth display device 50D shown in fig. 13 is used in the security gate 1 of each embodiment described below.

In the first embodiment, the light emitting elements 60 of the display device 50 are arranged along the outline of an X-shaped pattern or the like as shown in fig. 3. The display device 50 may be replaced with a fifth display device 50D shown in fig. 13. In the display device 50D, a combination of three types of light-emitting elements 60R, 60G, and 60B, red, green, and blue (R, G, B), respectively, is arranged in a matrix.

As shown in fig. 14, the conductor layer 53 is formed of conductor patterns 140, 141, 142, 143, 144, and 145 in the vicinity of the group of light-emitting elements 60R, 60G, and 60B of the display device 50D. Anodes of the light emitting elements 60R, 60G, 60B are commonly connected to the conductor pattern 140. The cathode of light-emitting element 60R is connected to conductor pattern 141, the cathode of light-emitting element 60G is connected to conductor pattern 142, and the cathode of light-emitting element 60B is connected to conductor pattern 143. The conductor patterns 144 and 145 are used for wiring of the other light emitting elements 60R, 60G, and 60B. The light emitting elements 60R, 60G, and 60B can be individually turned on by supplying dc power of a positive voltage selectively to the conductor patterns 141 to 143. Thus, the control device 30 can display any of photographs, graphics, characters, and moving images and still images including combinations thereof on the display device 50D by using the color of any of red, green, and blue light, or a mixed color of two or more of the red, green, and blue light.

Fig. 15 and 16 are first and second views showing the display of the second embodiment. In the security gate 1, the control device 30 is set to allow passage of a person from the-Y side to the + Y side and passage of a person from the + Y side to the-Y side as shown in fig. 1 and the like. The control device 30 is set for authentication using the authentication information obtained from the reader device 15. That is, in this setting, as long as the authentication is performed, the passage of the person from the public space to the private space and the passage of the person from the private space to the public space are permitted. In this setting, any one of the display devices 50D attached to the barrier 20 does not display any information unless the sensor 14 of the security gate 1 detects an approaching person.

In such a setting, the sensor 14 detects a person approaching from the-Y side of the security gate 1, that is, a person who wants to pass in the direction from the public space to the private space. In this case, as shown in fig. 15, the control device 30 causes the display device 50D attached to the barrier 20 to display an image of a character "welome" that is favorable for accessing the dedicated space, for a person who approaches and completes authentication using the authentication information obtained from the reader device 15. The controller 30 controls the driving mechanism 80 to open the shutter 20 on which the image is displayed.

On the other hand, in such setting, the sensor 14 detects a person approaching from the + Y side of the security gate 1, that is, a person who wants to pass from the private space to the public space. In this case, as shown in fig. 16, control device 30 causes display device 50D attached to barrier 20 to display "thank you |" that fades away access to the private space, for a person who approaches and completes authentication using the authentication information obtained from reader 15! "of characters. Then, the controller 30 controls the driving mechanism 80 to open the shutter 20.

In each embodiment, the controller 30 closes the shutter 20 opened by the driving mechanism 80 after a predetermined time has elapsed. In each of the embodiments, when a predetermined condition such as that the sensor 14 does not detect any more person or that a predetermined time has elapsed since the passage of the person, the control device 30 returns the display to the display device 50D to the initial state.

Third embodiment

Hereinafter, the display of the third embodiment will be described. Fig. 17 is a diagram showing a display of the third embodiment.

In commercial facilities, the security gate 1 is sometimes required to have not only transparency but also an optical decorative effect. In this case, as shown in fig. 17, the controller 30 causes the display device 50D attached to the barrier 20 to display a pattern for decoration while the approach of a person is not detected. In this case, when it is detected that a person approaches and authentication of the approaching person is performed, the control device 30 changes the display of the display device 50D attached to the barrier 20 as shown in fig. 9, 10, 15, and 16. The controller 30 controls the driving mechanism 80 to open the shutter 20.

Fourth embodiment

Hereinafter, a display of the fourth embodiment will be described. Fig. 18, 19, 20, and 21 are first to fourth views showing a display of the fourth embodiment. Fig. 18 to 21 show a case where the shutter 20 is completely opened and overlaps the transparent plate 13.

The control device 30 is set to allow passage of a person only from the-Y side to the + Y side of the security gate 1, that is, passage of a person from the public space to the private space. Then, the control device 30 is set to execute authentication using the authentication information obtained from the reading device 15. In this setting, any one of the display devices 50D attached to the barrier 20 does not display any information unless it is detected that a person approaches the security gate 1.

In this setting, the sensor 14 detects the approach of a person from the-Y side of the security gate 1. Further, the approaching person is authenticated by the authentication information obtained from the reader 15. In this case, the controller 30 controls the driving device 80 to bring the barrier 20 from the closed state to the fully opened state, and displays an image on the display device 50D attached to the barrier 20 as shown in fig. 18 to 21. That is, the controller 30 displays images of ">" shape patterns indicating the passing direction permitted by the security gate 1 on the display device 50D attached to the barrier 20 at predetermined time intervals, for example, at 0.25 second intervals, in the number shown in fig. 18 to 21 and in the order shown in these figures. The controller 30 controls the driving mechanism 80 to open the shutter 20.

This display returns to the display shown in fig. 18 and repeats after the display shown in fig. 21 ends. That is, in this case, controller 30 causes display device 50D attached to barrier 20 and superimposed on transparent plate 13 supported by frame 11 to repeatedly display a moving image representing the movement of an image having one or more figures indicating the direction of passage of security gate 1.

Fifth embodiment

Hereinafter, a display of the fifth embodiment will be described. Fig. 22 is a diagram showing a display device 50D mounted on a transparent plate 13 supported by a frame 11 in the security door 1. Fig. 23, 24, and 25 are first to third views showing the display of the fifth embodiment.

Fig. 22 shows a display device 50D mounted on the transparent plate 13 as a display device. Fig. 23 to 25 show a display mode in which the shutter 20 is completely opened and is overlapped on the transparent plate 13.

As shown in fig. 22, a display device 50D may be mounted on the transparent plate 13 supported by the frame 11. The control device 30 is set to allow passage of a person only from the-Y side to the + Y side of the security gate 1, that is, passage of a person from the public space to the private space. The control device 30 is set to execute authentication using the authentication information obtained by the reader device 15. In this setting, any one of the display devices 50D attached to the barrier 20 does not display any information unless it is detected that a person approaches the security gate 1.

In this setting, the sensor 14 detects the approach of a person from the-Y side of the security gate 1. Further, the reader 15 reads information for authentication. When the approaching person is authenticated, the controller 30 controls the driving mechanism 80 to open the barrier 20, and three images of ">" shaped graphics indicating the direction in which the communication is permitted are displayed on the display device 50D attached to the barrier 20 as shown in fig. 23. In this case, as shown in fig. 24, the control device 30 displays an image of a ">" shaped figure indicating the direction of permission of the communication on the display device 50D attached to the transparent plate 13 with three horizontal shifts.

When the completely opened barrier 20 and the display device 50D attached to the transparent plate 13 are overlapped with each other, as shown in fig. 25, a person who wants to pass through the security gate 1 can see images of six figures. That is, when the barrier 20 and the transparent plate 13 overlap each other, images of graphics displayed on the display device 50D attached to the barrier 20 and the transparent plate 13 are also displayed so as to overlap each other.

Sixth embodiment

hereinafter, the display of the sixth embodiment will be described. Fig. 26 is a diagram showing a configuration of the barrier 20 in which the display device 50D and the prism-shaped frame 202 are sandwiched between two transparent plates 200. Fig. 27 is a diagram showing a display of the sixth embodiment.

As shown in fig. 26, the barrier 20 may be formed by two transparent plates 200, and the display device 50D may be sandwiched between the two transparent plates 200. The frame 202 shown in the display device 50D shown in fig. 26 has a prism-shaped cross section, and reflects light emitted by the light-emitting element 60 leaking in a direction horizontal to the transparent films 51 and 52, in a direction perpendicular to the transparent films 51 and 52. When the image of the figure shown in fig. 10 is displayed on the display device 50D of the barrier 20 shown in fig. 26, as shown in fig. 27, a person who wants to pass through the security gate 1 can see the image of the figure surrounded by the frame 202.

Seventh embodiment

Hereinafter, a display of the seventh embodiment will be described. Fig. 28 and 29 are first and second views showing the display of the seventh embodiment. As shown in fig. 28, the display devices 50D are attached to the two shutters 20 of the security gate 1 from both the + Y side and the-Y side, respectively. When there is no person passing through the security gate 1, the control device 30 displays an image of an upward arrow figure indicating the direction of travel of the person on the display device 50D attached from the + Y side of each of the two flaps 20. When there is no person passing through the security gate 1, the controller 30 displays an image of an upward arrow pattern indicating the direction of travel of the person at a position shifted from the display device 50D attached from the + Y side of each of the two flaps 20.

As shown in fig. 4 and 5, the light emitting element 60 of the display device 50D emits light to both surfaces of the display device 50D. On the other hand, the light emitted from the light emitting element 60 is also reflected by the surface of the baffle 20 and the display device 50D. Therefore, a person approaching security gate 1 can see both the light directly emitted from light emitting element 60 and the reflected light. As a result, as shown in fig. 29, the person who passes through the security gate 1 can be given the impression that the image displayed on the barrier 20 is stereoscopic and has a deep depth. Further, by changing or blinking the images displayed on the display devices 50D respectively attached to both sides of the barrier 20 in synchronization with the operation of the barrier 20, a more impressive display can be realized.

Eighth embodiment

Hereinafter, an application of the display device 50D to the automatic door 9 will be described as an eighth embodiment. Fig. 30 is a diagram showing the automatic door 9 to which the display device 50D is applied. As shown in fig. 30, the display device 50D is attached to a lower portion of a guard rail 92 that prevents a collision with a person or an object when the automatic door 9 is operated. In the automatic door 9, on the display device 50D, an image of a figure as shown in fig. 9 and 10 is displayed to a person passing through the automatic door 9. Further, by further providing the reading device 15 in the automatic door 9, it is possible to authenticate a person who wants to pass, and to permit or not permit the passage depending on whether or not the person is authenticated.

According to the embodiments described above, it is possible to maintain the high light transmittance of the barrier in the normal state and to perform effective display that is easy to understand for a person passing through the security gate or the automatic door as needed. Further, according to the embodiment, the transmittance of the display device is improved, so that the infrared sensor, the image recognition camera, and the like can be easily disposed on the security gate, and the design for the disposition can be easily performed. Therefore, according to the embodiment, the degree of freedom in design can be improved while ensuring design and safety.

Modifications of the first to eighth embodiments will be described below. In the flexible cable 70 in the frame 11 shown in fig. 13 and the like, when the shutter 20 rotates, there is a possibility that distortion and tension are generated. Such twisting and tension may cause disconnection of the wiring of the flexible cable 70. Such disconnection can be prevented by imparting a moderate deflection to the flexible cable 70 in the frame 11. Alternatively, when the shutter 20 is rotated only in one direction, such disconnection can be prevented by twisting the flexible cable 70 in advance in the direction opposite to the rotation.

Fig. 31 and 32 are first and second views showing modifications of the baffle 20 to the frame 11. As shown in fig. 31, a reinforcing plate 78 may be added to the portion where the bezel 20 is attached to the frame 11, the reinforcing plate hiding and reinforcing the connection portion between the flexible cable 70 and the display device 50D.

In addition, if it is possible to try to hide or the like so as not to be conspicuous in the bezel 20, the display device 50D may be screwed to the bezel 20. When the collision prevention mark is added, the screw-fastening portion between the bezel 20 and the display device 50D may be hidden by the collision prevention mark, or the collision prevention mark itself may be screwed and used for screw-fastening between the bezel 20 and the display device 50D.

If the light transmittance of the baffle 20 can be maintained or the baffle can be hidden inside the frame 11, a wiring material 76 connected to the display device 50D by a conductive paste may be used instead of the flexible cable 70 as shown in fig. 32. In this case, the connection portion between the display device 50D and the wiring member 76 is provided inside the frame 11 and hidden.

Fig. 33, 34, 35, and 36 are first to fourth views showing modifications of the display of the baffle 20 shown in fig. 9 and 10. In fig. 9, an example is shown in which X-shaped images are displayed on the barriers 20 of the security gate 1, but one X-shaped image may be displayed across both sides of the barrier 20 as shown in fig. 33. In addition, although fig. 10 illustrates a case where images of circular figures are displayed on the barriers 20 of the security gate 1, one image of a circular figure may be displayed across both sides of the barrier 20 as shown in fig. 34.

If the circular and X-shaped images shown in fig. 9 and 10 indicate permission and non-permission, the non-japanese speaker may not understand the images. Therefore, as shown in fig. 35 and 36, the permission and the non-permission of passage may be indicated to the person passing through the security gate 1 by displaying characters of "Unaccetable" or "OK" on the display device 50D attached to the barrier 20 instead of the images of the X-shape and the circular pattern.

Next, a modification of the display shown in fig. 28 and 29 will be described. Fig. 37 to 39 are first to third views showing the display of the shutter 20 and the transparent plate 13. In fig. 37 to 39, a display mode based on the barrier 20 and the transparent plate 13 is shown, not only on the barrier 20, but also on fig. 28 and 29.

As shown in fig. 37, when the barrier 20 is overlapped with the transparent plate 13 in a state where no display is performed, the control device 30 displays an image of a right arrow-shaped figure showing a direction in which a person passes on the display device 50 attached to the barrier 20. Further, as shown in fig. 38, the controller 30 displays an image of the same pattern as the pattern displayed on the barrier 20 on the display device 50D attached to the transparent plate 13 with a shift in position. When such display is performed, as shown in fig. 39, when the shutter 20 is completely opened and overlaps the transparent plate 13, the same effect as that of the image shown in fig. 29 is given to the image displayed thereon. The control device 30 may display an image of the same pattern as the pattern displayed on the barrier 20 on the display device 50D attached to the transparent plate 13 so as to overlap the pattern without shifting the position.

Fig. 40 is a view showing a modification of the display of the shutter 20 and the transparent plate 13 shown in fig. 37 to 39. Although fig. 37 to 39 illustrate the case where the image of the arrow-shaped figure is displayed on the barrier 20 and the transparent plate 13, the display contents on the barrier 20 and the transparent plate 13 are not limited to the image of the arrow-shaped figure, and may be, for example, a plurality of circular figures as shown in fig. 40.

In the security gate 1, transparent display devices 50, 50C, 50D including a light emitting element 60 are disposed in transparent portions such as the barrier 20 and the transparent plate 13, and still images and moving images representing various figures, characters, patterns, and the like are displayed. Therefore, according to the safety door 1 of the embodiment, the degree of freedom in design can be improved while ensuring design and safety.

In addition, although the double-opening safety door 1 having the two shutters 20 that open and close by rotation has been described above, the safety door 1 may be of a single-opening type having only one shutter 20. In addition, the safety door 1 may be a lateral sliding type having a barrier 20 sliding in a lateral direction. In addition, although the display of the display devices 50, 50C, and 50D in the embodiment is performed in the barrier 20 and the transparent plate 13, the display may be performed in other portions of the security door 1 such as the transparent plate 120 as long as the display devices 50, 50C, and 50D exhibit their characteristics.

In each of the embodiments and modifications, the number of light-emitting elements 60 and the color of light included in display devices 50, 50C, and 50D may be changed as appropriate according to the use of security door 1, and the like. The transparent plates 12 and 13 may have a rectangular shape, or may have a square shape, for example. The vertical and horizontal dimensions of the baffle 20 are arbitrary, and the shape of the baffle 20 may be, for example, a rectangle, instead of a square. The height-direction length of the baffle plate 20 may be determined in consideration of the height of a person.

The display device 50D may include light-emitting elements 60 arranged in a matrix and configured to emit only one of red, green, and blue light. Further, 3 display devices 50D for displaying images by using any one of red, green, and blue light may be mounted on the barrier 20 or the transparent plate 13 in a stacked manner. By using the barrier 20 or the transparent plate 13 to which the 3-piece display device 50D is attached in this manner, the controller 30 can display an image of red, green, blue, and a color synthesized from light of these colors on the barrier 20 or the transparent plate 13.

In addition, as the intermediate resin 55, a thermosetting resin may be used in addition to the thermoplastic resin. In order to cope with external impact, the display device 50 may be sandwiched between acrylic plates or the like and then bonded to the barrier 20 with a transparent adhesive. The display device 50 may be supported without being sandwiched between acrylic plates or the like. In addition, although fig. 10 illustrates the case where two display devices 50 are superimposed, the display devices 50 may be configured to display an image of a circular pattern and an image of an X-shaped pattern by switching them.

In fig. 30, the display device 50D is shown as being attached to the guard rail 92, but the display device 50D may be attached to a fixed portion of the door 90 in an automatic door, or may be attached to a sliding portion of the door 90 by performing a study of the purpose of power supply. The plurality of circular patterns shown in fig. 40 may be displayed by a set of 3-color light-emitting elements 60R, 60G, and 60B of red, green, and blue (R, G, B), or by a white light-emitting element 60.

According to the safety door of at least one embodiment described above, the degree of freedom in design can be improved while ensuring design and safety.

Although the embodiment of the present invention has been described, the embodiment is provided as an example, and is not intended to limit the scope of the present invention. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention.
