Description

  The present invention relates to an exit management system, and more particularly, to an exit management system for a management target (a gate provided in a building, a gate provided on a site, etc.), for example, a managed person living in a nursing facility that provides care for a large number of elderly people. The present invention relates to an exit management system for preventing a person (for example, an elderly person with dementia) from going out from an entrance / exit of a management area (for example, a building) and tricking a place outside the site.

 It is an aging society, and the social reality is that as people get older, they are taken care of by hospitals and nursing homes. In addition, the older people become, the higher the level of dementia. For example, in a care facility that cares for a large number of elderly people, a managed person (demented elderly person) may go out without knowing and make a fuss. Therefore, in nursing care facilities, etc., an operation button is provided in a place where the manager cannot operate, and when the administrator operates the operation button, an apparatus that opens an automatic door is employed. However, such an automatic door opening device based on the operation of the operation button requires a human burden in that the administrator must always be there.

Therefore, without burdening the administrator, nurses and managers of houses, hospitals, nursing homes, etc., including private housing and collective housing, can dedicate one or more managed persons within the site When managing not a room but a relatively large indoor space with a front door, the managed person goes out to protect the body and life of the managed person (for example, elderly people with dementia). It is desirable to prevent this.
By the way, in Patent Document 1, when an ID reader receives a radio wave transmitted from a non-contact card, and identification information (personal information or ID information) included in the radio wave matches information recorded in advance. The door lock is unlocked. Communication between non-contact cards (responders) and ID readers (interrogators) regardless of the type of IC card inserted or held in the IC reader or the type of call answering within the radio wave irradiation range. Prior art using technology is a well-known matter.

 However, in the communication system of a non-contact type card (duck: responder) and ID reader (interrogator), when the manager does not possess or wear the card, or the manager asks the manager “ In the case where the “duck: responder” is not provided, there is a risk that the mechanical lock or the operation button type electric thumb turn may be unlocked. Further, even when the electric lock control panel unlocks / opens the automatic door by so-called numeric keypad operation input (password code input), there is a possibility that the door is unlocked / opened similarly to the electric thumb turn.

 Therefore, not the interrogator and responder call method, but also the interrogator and responder call method, take the "face" of the person to be managed with the camera, and use the image information to enter / exit the room. A system for identifying a person can be considered (Patent Document 2, Patent Document 3, etc.).

 For example, Patent Document 2 discloses a face authentication apparatus A that extracts feature points of a person's “face” and views the feature points as identification information such as an ID. Referring to FIG. 1 of this Patent Document 2, an optical first camera 6 that captures a feature point of a human face that has passed through a condenser lens 3, a half mirror 4, and a first filter 4, and the condenser lens. 3. Face authentication apparatus A combined with optical system second camera 6 for photographing the contour of the face of a person who has passed through half mirror 4 and second filter 8, and authentication unit 7 of face authentication apparatus A includes: It is possible to authenticate (determine) the face of a person corresponding to the multiple templates by comparing the facial feature points acquired by the optical system first camera 6 with a large number of templates recorded in the storage unit in advance. It is described that it is possible (Claim 1, paragraph 0037). And it is described that the system control board G of the face authentication apparatus shown in FIG. 4 can also unlock the electric lock of the electric lock control board D if the authentication result of the face authentication apparatus A is OK. (Paragraph 0038).

 Therefore, the “face” of the management subject to be managed is taken with a digital camera, and the “feature point information” acquired in the image database related to the feature point of the “face” of the management person stored in the storage unit is matched to The lock control panel can prevent the automatic door from being unlocked and opened.

  Patent Document 3 combines the concept of Patent Document 1 (non-contact type authentication means using an IC card and an IC reader) with the concept of Patent Document 2 (face authentication means using one or more face images). An entry / exit management system is disclosed. The entrance / exit management system of Patent Document 3 is a so-called anti-passback system (invention of an apparatus having a function of rejecting exit if the fact of entering a room is not confirmed).

  However, in the face authentication devices of Patent Document 2 and Patent Document 3, the electric lock control panel provided directly or indirectly on the door can prevent the automatic door from being unlocked or opened. However, in the case of a lock that can be unlocked only mechanically, the thumb turn knob is operated, and in the case of an electric thumb turn device, the operation button is operated to input an unlock signal to the electric lock control panel. Depending on the locking / unlocking system, it may be unlocked. Further, when the electric lock can be unlocked not only electrically but also by mechanical operation, there is a problem similar to that of the mechanical lock.

 Therefore, the fact that the face authentication device has identified the person to be managed (for example, an elderly person with dementia) in a predetermined area near the inner wall surface of a gate (door) of a building, for example, is a specific one of mechanical means or electrical means. It is desired to prevent the lock from being unlocked quickly and reliably by the configuration.

Japanese Patent Laid-Open No. 3-228988 Japanese Patent No. 4981700 Japanese Patent No. 4460234

 The main problem of the present invention is that a managed person (for example, a demented elderly person, a child, etc.) residing in a private house, an apartment house, a care facility for nursing a large number of elderly people, a hospital, etc. responds (tag). Even if you don't own or wear it, you can quickly and reliably use a specific configuration of either mechanical means or electrical means, for example, to go outside from the entrance / exit of an exclusive part of the building. In addition, the lock is prevented from being unlocked (the advantage is that the storage process is fast and that the lock can be manufactured at low cost). In addition, for example, when a person is trapped in a predetermined area on the inner wall surface of a gate (door) of a building, or when he / she goes out from a site equipped with a gate, the image of the person to be managed is accurately and visually confirmed as a countermeasure against wrinkles. You can be sure of that. In addition, it is possible for people other than the supervised person to go in and out as usual, to restrict the go-out according to the convenience of the manager, to know the specific information of the supervised family, the history of the supervised person Other purposes, such as recording, become the main subject of the present invention when it becomes a component of the independent claims.

  The exit management system according to the present invention includes a human detection means for detecting a person to be managed in a predetermined area of a management area, and a “face” and a “figure” of the person to be managed by a camera based on a detection signal of the person detection means. It is determined whether or not only the pose information acquisition means for taking a picture, the pose information acquired by the pose information acquisition means, and the registration information previously recorded in the storage unit as identification information such as ID of the face and the figure The control unit that controls the prohibiting member that prohibits the operation of the operation portion of the gate lock unit when determining whether the determination unit and the form information and the registration information match or does not match It is characterized by having.

  Further, the exit management system of the present invention provides a human detection means for detecting a person to be managed in a predetermined area of the management area, and a camera's "face" and "appearance" based on the detection signal of the person detection means. It is determined whether or not only the pose information acquisition means taken by the camera, the pose information acquired by the pose information acquisition means, and the registration information previously recorded in the storage unit as identification information such as ID of the face and the figure If the determination means and the appearance information and the registration information match or do not match, even if the operation part of the gate lock means is operated, the operation part is operated. It has a control part which controls a prohibition member so that force may not be transmitted to a dead bolt.

  Furthermore, the exit management system of the present invention is configured to detect a person to be managed in a predetermined area of the management area, and to detect the “face” and “form” of the person to be managed based on a detection signal of the person detection means. Whether or not the pose information acquisition means to be taken by the camera, only the pose information acquired by the pose information acquisition means, and the registration information recorded in advance in the storage unit as identification information such as ID of the face and appearance If it is determined that the determination means for determining and the appearance information and the registration information match or do not match, the unlocking signal is generated even if the operation portion of the gate lock means is operated. It has a control part which controls a prohibition member so that it may not flow into a control part, and opens a switch circuit. In addition, when the present invention is a so-called business model patent, any one of the exit management system, the management terminal, and the higher-level server is connected to the family terminal via the Internet when the specific information of the managed person is acquired. It has a transmission means which transmits this specific information including a managed person's picture.

  The "gate lock means" here is an ordinary thumb-turn device that operates in the unlocking direction with the thumb-turn knob with a finger, an electric thumb-turn that is unlocked based on the operation of the operation button, an operation panel called a so-called numeric keypad An electric lock that is unlocked by a control signal of a so-called electric lock control panel based on an operation signal (input of a password) of a plurality of operation buttons is included.

  In addition, in the independent claims of claim 1, claim 5, and claim 7, the precondition that the prohibiting member is locked (locked) or unlocked (unlocked) at the initial stage is not limited. The mode of the prohibiting member may be any.

  Further, the concept of “management area” is as defined in the specification. The gate is preferably a building door.

  (A) According to the present invention, according to the configuration described in the independent claim, a dementia elderly person (managed person) who lives in a private house, a housing complex, a nursing facility for nursing a large number of elderly people, a hospital, etc. Even if the responder (tag) is not possessed or mounted, it is possible to reliably prevent the user from going outside from the entrance / exit of the management area. Further, since the authentication information is not combined with other authentication information other than the “appearance”, there are advantages such as a fast storage process and a low cost production. Of course, the person being managed can be confirmed accurately visually. It also has the advantage of being a decision material during the investigation.

  (B) The dependent claim of the present invention is that, particularly when the gate lock means of the exit management system is an electric thumb turn, the prohibition member is provided so that the electric thumb turn is quickly unlocked and the electric thumb turn is not unlocked. Can be controlled. Therefore, since the electric thumb turn can be used alone, or with an existing lock, or with a locking device such as an electric lock, a person other than the person to be managed can enter and exit as usual.

  (C) In particular, in the invention described in claim 11, since the cameras constituting the human detection means and the posture information acquisition means are physically integrated and provided on the upper side of the inner wall surface of the door, Wiring between them is not necessary, and “face” information can be taken from substantially the front.

  (D) In the invention described in claim 12, any one of the control unit, the management terminal, and the upper server transmits the specific information to the family terminal via the Internet when the specific information of the managed person is acquired. Therefore, a family member who has obtained a so-called business model patent and has acquired specific information including an image of the manager at the family terminal can cooperate with the manager's countermeasures to prevent wrinkles.

Perform various functions such as control.
In addition, the control unit (CPU) 3 includes a determination unit 3a, a timer 3b, a prohibiting member (locking unit) control unit 3c, and the like. The image storage unit 4 stores the identification information b of the manager H in advance.

  Then, the determination unit 3 a of the control unit (CPU) 3 makes a determination by matching the identification information b registered in the image storage unit 4 with the image information a acquired from the form information acquisition unit 20. When a determination result is output from the determination unit 3a of the control unit (CPU) 3, the timer 3b is started, and the prohibition member (locking unit) control unit 3c is connected to, for example, a gate (door) D of a building, for example. The provided prohibition member 41 is controlled with respect to the operation member 32.

In the embodiment, the control unit (CPU) 3 includes an operation portion (operation member) 32 for unlocking the lock state (locking) of the gate lock unit 31 provided on the door D based on the determination result of the determination unit 3a. By controlling the prohibiting member 41 provided on the door D so that the operating force is not transmitted to the dead bolt of the gate locking means 31, for example, the operating part is prohibited from rotating the operating part (operating member) 32. (Operation member) A mode in which the rotation operation of the operation member 32 is idled, an appropriate switching circuit of the gate lock means 31 is opened, and the like is adopted.
The appearance information acquisition means 20 takes a picture of the “face” and “appearance” (preferably both) of the person H to be managed by the camera 22, and registers the features of the image information a of the photograph and the ID in advance. The managed person is determined by comparing with certain identification information b. It is desirable to arrange such a form information acquisition means 20 in a common part of the building (not shown).

  Further, the determination result of the determination means 3a (preferably specific information including the image of the person to be managed) is output control section (transmission means) 5 of the exit control device (exit control section: main body) 1 in order to inform at least the family. Either the output control unit (transmission unit) of the management terminal 7 or the output control unit (transmission unit) of the higher-level server 9 transmits the specific information of the managed person H to the family terminal 10 via the Internet 8. desirable.

The “management area” in this specification refers to a place where a manager who does not have permission to pass is to be kept in a predetermined space of a building or site, for example, at the entrance of the place. Is provided with a gate (gate) that allows a person having a passage permission authority to pass therethrough while preventing the person to be managed from passing through the exclusive part.
Therefore, specific examples are listed as follows (a) to (d), and the gate of the exclusive part is not limited to these, but comprehensively determines the purpose of the invention, the management subject, the use of the building, etc. To be determined.

  (A) “Exclusive part in the case of a private house” means the internal space of the building (walls, objects, etc.) including the inner wall surface of the lock-entrance gate with reference to the lock-entrance gate used by the family when going out Including each room, living room, living room as a conversation space, toilet, bathroom, etc. Therefore, although there is no concept of “shared part in the case of a private house”, in accordance with “common part of condominium” and “shared part of nursing care facility”, the site including the outer wall of the entrance gate with the lock (Including walls, objects, etc.) Specifically, it refers to the inside of the cage and the site to the gate.

  (B) “Exclusive part in the case of condominium” means the scope of the exclusive part prescribed in Article 7, Article 7 of the Condominium Standard Management Regulations formulated by the Ministry of Land, Infrastructure, Transport and Tourism in January 2004. This refers to the interior space (including walls, objects, etc.) of the building including the inner wall surface of the entrance gate, which is the same as the specific example of the exclusive part in the case of a private house. Therefore, “community common area” means the range of the second common part in the separate table based on the same standard management regulations. Specifically, the entrance hall of the building, the hallway of the building, the elevator hall of the building, the common Toilets are included.

(C) In a nursing care facility that provides a service, the distinction between “exclusive part” and “shared part” is not clear, and there are various patterns depending on the operation mode of the facility.
When referring to a “living room” where the elderly living in the facility live as the “exclusive part of a nursing care facility”, it refers to the interior space of the room including the inner wall surface of the room gate, and many people when going out When referring to the interior space of the building including the inner wall of the entrance gate, based on the entrance gate to be used, not only each room but also each facility (functional training room, multipurpose hall, living room floor where newspapers and magazines can be read, Health management room, diagnostic room, bathroom, bathroom, conversation space, lobby lounge, etc.).

  In the case of the former, “the common part of the nursing care facility” means the managed site including the outer wall of the gate and other “facility” on the basis of the gate coming out of the room. In the latter case, otherwise The inside of the management target site including the outer wall surface of the entrance gate with the entrance gate as a reference.

  (D) When there is a site for the management object, it means the site. In this case, the gate locking means is provided on the gate or the like.

(2) First Embodiment A first embodiment will be described with reference to FIGS. First, FIG. 1 is a block diagram showing the overall configuration of the exit management system X of the present invention (including the establishment of business model patents). In the exit management system X of the first embodiment, the managed person H operates, for example, the operation part 32 of the gate lock means 31 provided on the inner wall surface of the door D from the exclusive part of the building in the unlocking direction. Basically, on the condition that the unlocking of the gate locking means 31 is prevented, the person detection provided in the exclusive part so as to detect the manager H in the predetermined area A of the exclusive part. Based on the detection signal of the means 21, the human detection means, the posture information acquisition means 20 for taking a picture of the “face” or “form” of the managed person with the camera 22, and the posture information acquired by the posture information acquisition means The exit control device 1 processes (image information). The exit control device 1 identifies the posture information (image information) a acquired by the posture information acquisition means, and the identification information b such as the face and the feature of the face such as an ID. Registered information previously recorded in the image storage unit 5 as When the determination means 3a for determining whether or not and the appearance information a and the registration information b match or do not match, the gate lock means 31 is determined. And a prohibiting member control section 3c for controlling the prohibiting member 41 that prohibits the operation of the operating portion 32.

(3) Configuration / Operation of Exit Control Device (Exit Control Unit: Main Body) 1 The exit control device (main body) 1 has an input control unit 2 as described in “Basic Concept of the Present Invention” in (1). A control unit (CPU) 3, an image storage unit 4, and an output control unit (transmission means) 5. Although not shown in particular, the exit control device (main body) 1 includes a power supply unit, alarm means, and the like. For supplementary explanation, the data buffer of the image storage unit 4 stores, for example, identification information b assigned to all the managers living in the care facility. The memory of the image storage unit 4 stores an ID code for identifying each of the exit control devices (main body) 1 when there are a plurality of the exit control devices (main body) 1. The output control unit 5 connects the control unit 3 and the management terminal 7 with a line. In the embodiment, the output control unit 5 is also connected to the Internet 8, which is a typical example of a communication network.

When the control unit 3 of the exit control device (main body) 1 fetches the posture information (image information) a from the posture information acquisition unit 20, the determination unit 3a determines that the posture information (image information) a is the identification information b. Then, it is determined whether or not the same information as the identification information is registered by referring to the data buffer (a number of templates (not shown)) in the image storage unit 4. In the embodiment, when it is determined that the same information is registered (recorded), the operation of the prohibiting member 41 is controlled.
In other words, if the determination unit 3a determines that the identification information b and the registration information a match (embodiment) or does not match, the prohibition member control unit 3c of the control unit 3 is determined. Prevents the operation of the operation portion (thumb-turn knob in the embodiment) 32 of the gate-locking means (in the embodiment, thumb-turn device) 31 so that the gate-locking means 31 provided on the door D is not unlocked. The prohibiting member 41 is controlled.

The prohibiting member 41 of the first embodiment locks the thumb turn knob 32 of the thumb turn 31. Then, the control unit (CPU) 3 of the exit control device (exit control unit: main body) 1 controls the prohibiting member 41 and simultaneously starts the timer 3b to count for a predetermined time, thereby maintaining the protection state of the prohibiting member 41. To do. On the other hand, the control part 3 cancels | releases the defense state of the prohibition member 41, and resets a timer after fixed time progress. At this time, preferably, this form information is sent to the management terminal 7 or the like via the transmission means 5.
By the way, the control unit 3 controls an alarm means (alarm sound generation unit) (not shown) to generate an alarm sound after sending the alarm information to the management terminal 7 after resetting or before the timer. .

  In the embodiment, not only the control unit (CPU) 3 of the exit control device 1 but also either the management terminal 7 or the higher-level server 9 receives the specific information of the managed person H via the Internet 8. Since the family terminal 10 has a transmission means for transmitting the specific information, a so-called business model patent is established, and the family and the like who have acquired the specific information at the family terminal 10 cooperate with an administrator's countermeasure for preventing wrinkles (FIG. 1). , See FIG.

(4) Content Diagram of Image Storage Unit and the like of Exit Control Device (Exit Control Unit: Main Body) 1 FIG. 3 is a block diagram of the exit management system including the content of the image storage unit and the like. In FIG. 3, reference numeral 20 denotes the above-described form information acquisition means (image input / output unit), 2 denotes an input control unit (appearance area extracting unit) of the exit control device (main body) 1, 2a denotes a face, a physique, clothes, and the like. 3 is a feature point extraction unit in the control unit, and 4 is an image storage for storing feature point information (image information) a obtained by the feature point extraction unit and pre-registered identification information b. , 3a is a determination means (collation) of the control unit, 7 is a management terminal (a terminal in the management room), 8 is a communication network, and 9 is an upper server (for example, a cloud).

  With reference to FIG. 3, functions of the posture information acquisition unit 20 and the control unit 3 will be additionally described. The appearance information acquisition means 20 includes the camera 22 and the appearance information transmission means 23 as described above. Since the control relationship is a so-called IC, for example, the exit management system of the exclusive part of the building uses the image input / output unit 20 built in the camera 22, in the embodiment, the outline information of “face” and “form”. Obtained by the face / form region extraction unit 2 (input control unit of the exit control device 1) to be acquired, the feature point extraction unit 3 that extracts feature points from the face / form region extraction unit 2, and the feature point extraction unit The determination means 3a for collating the information with the identification information b of the image storage unit 4 corresponding to the form database, and transmitting the determination result to the host server 9 via the management terminal 7 and / or the communication network 8 via the line Each of which has an output control unit 5 that performs the above-described operation.

  The face / form region extraction unit 2 extracts the “face” and “form” of the manager H who hesitates from the raw still image (embodiment) or video captured by the image input / output unit 20. The feature point extraction unit 3 that generates the extraction information 2a and is a function of the control unit, for example, features such as the position of the eyes and nose on the face part, height, physique, and clothes from the extracted information 2a of the appearance Point information (image information) a is generated and passed to the determination means 3a. The determination unit 3a compares (matches) the identification information b of the managed person H registered in the image storage unit 4 with the feature point information a. When the managed person H matches or does not match, it matches. Sends the specific information (“ID”, “face”, “form” of the managed person H) that can identify the managed person H to the output control unit 5 as determination information. Then, the output control unit 5 transmits the specific information including the image of the managed person directly to the family terminal 10 via the Internet 8 or via the management terminal 7.

(5) Contents of Image Storage Unit 4 FIG. 4 is a content diagram stored in the data buffer of the image storage unit 4. Although details are omitted, the data buffer of the image storage unit 4 includes identification information (face information, appearance information, etc.) b regarding the appearance. That is, a factor code related to the ID, name, gender, door, face information, figure information, and feature point information (feature amount) of a manager who may be hesitant is registered. The contents of the data buffer of the image storage unit 4 are simplified to a degree sufficient for the description of the embodiment, and the factor code or the derived code derived from the factor code is not limited to the above.

(6) Configuration of Gate Locking Unit 31 and Others FIGS. 4 to 8 are schematic explanatory views of the gate locking unit 31 and the prohibiting member 41 of the first embodiment. Referring now to FIG. 6, the gate lock means 31 is a manual thumb turn device, while the prohibiting member 41 is an actuator such as a drive motor or a solenoid. FIG. 6 shows a “solenoid” as an example of the prohibiting member 41 of the first embodiment, but a drive motor may of course be employed as appropriate. As is well known, when the solenoid 41 is energized or de-energized, the operating rod 42 extends. Therefore, in the embodiment, the distal end portion of the operating rod 42 of the solenoid 41 is formed in, for example, a bullet shape or a tapered shape, and on the other hand, the outer peripheral surface of the thumb turn shaft 33 facing the tapered distal end portion of the operating rod 42 is wedge-shaped or An engagement groove 34 such as a substantially V-shape or a substantially U-shape is formed. FIG. 6 shows that, for example, the operating rod 42 of the solenoid 41 extends when energized, and the tapered tip end portion 42 a engages with the engaging groove 34 of the thumb turn shaft 33. As a result, the outer end of the thumb turn shaft 33 is engaged. It is a schematic explanatory drawing which shows that the rotation of the operation part 32 integrally provided in the part was prevented. When the rotation of the operating portion 32 is prevented by the operation of the prohibiting member 41, naturally the non-circular or polygonal fitting portion 33a does not rotate, so that the cam (thumbturn dharma) 34 does not rotate in the unlocking direction. . Therefore, the deadbolt 36 shown in FIG. 6 does not move (still locked).

(7) Flowchart Showing Operation of Exit Control Device 1 FIG. 9 is a flowchart showing operation of the exit control device 1. Since the gate lock means 31 of the embodiment is a manual thumb turn device (usually a general mechanical lock), an administrator (not shown) operates the operation portion 32 of the thumb turn device in advance to lock the dead bolt. Of course, in the case of an electric thumb turn, the operation button is operated to lock the dead halt.

  The gate lock means may be in an “unlocked state” when 31 is an electric lock. In such a case, the exit management system locks the gate lock means (electric lock 31). At the same time, the prohibition member is controlled so that the gate lock means is not unlocked.

  Therefore, first, in step S10, the determination unit 3a of the control unit 3 of the exit control device (main body) 1 has acquired (received) the image information a of the manager H in the predetermined area A by the appearance information acquisition unit 20. Determine whether or not. In this determination, if it is determined that the image information a is not acquired, step 10 is repeated. If the image information a is acquired, the process proceeds to step S12, and whether the image information a matches the registered identification information b. Determine whether.

  In the embodiment, when the image information a matches the registered identification information b, the information does not match (for example, the image information held by all the family members and the image information of the parent of the identification card constituting the family). Is a design change example.

  If it is determined in the above determination that it is not already registered, the process proceeds to step S27 described later. On the other hand, if it is determined that it is already registered, the timer 3b is started in step S14. After the timer 3b is started, the prohibiting member 41 is operated in step S16.

  Since the gate locking means 31 of the embodiment is a manual (mechanical) thumb-turn device, the controller 3 of the exit control device (main body) 1 energizes or deenergizes a solenoid as an example of an actuator, 42 is extended. The tip of the solenoid actuating rod 42 is formed in, for example, a bullet shape or a tapered shape, so that, for example, a wedge shape or a substantially V-shaped, approximately formed in an appropriate location on the outer peripheral surface of the thumb turn shaft constituting the thumb turn device 31. The bullet-shaped tip is engaged with an engagement groove such as a U-shape, and the operation portion (thumbnail knob) 32 provided at the outer end of the thumb-turn shaft is prevented from rotating in the unlocking direction.

  Next, after the operation of the thumb turn device 31 is blocked by the prohibiting member 41, the process proceeds to step S18, where the output control unit 5 directly connects to the family terminal 10 via the Internet 8 or via the management terminal (terminal of the management room) 7. Then, the specific information including the image of the manager is transmitted. Thereafter, the timer is reset in step S20, and the process proceeds to step 22 to output an alarm signal.

  By the way, in step S16 of the above flow, when the prohibiting member 41 does not operate, the process proceeds to step S17, and when it is determined that the predetermined time has not elapsed, step S16 is repeated. When the unlocking signal is acquired from the locking means releasing means (not shown), or in the embodiment, on the condition that a certain time (for example, 2 minutes, 3 minutes, etc.) has passed, the prohibiting member 41 is set to the initial state in step S25. If the forbidden member 41 is in the initial state, the non-blocking state is maintained as it is. In step S27, information indicating that the person to be managed H has been separated from the predetermined area A on the inner wall surface of the door is output, and in step S28, the timer 3b is reset.

  As described above, in the first embodiment, the determination unit 3a of the control unit 3 determines whether the registration information matches or does not match when the image information a is acquired from the appearance information acquisition unit 20 instead of the ID information of the tag. The operation of the operation part (operation member including the operation shaft and power transmission means) for the gate lock means 31 is blocked, and the face image information indicating who is to be managed within a certain time from that point is obtained. It is possible to prevent the manager H, family, and the like from being informed by the transmitting means and preventing the manager H from going out of the exclusive part of the building, for example, so as to be hesitant.

  Therefore, a private residence, a housing complex, a care facility that cares for a large number of elderly people, a supervised person living in a hospital, etc. (eg, elderly people with dementia, children, etc.) possess and wear a responder (tag). Even if it is not, it is possible to quickly and reliably use a specific configuration of either mechanical means or electrical means to go out of the gate without permission from the gate provided at the entrance of the exclusive part of the building. The lock can be prevented from being unlocked.
