This makes it possible to improve the accuracy of authentication.

ADVANTAGE OF THE INVENTION According to this invention, the precision of the authentication using biometric information can be improved.

It is a figure which shows the structure of the door which concerns on embodiment. FIG. 10 is a diagram showing an example of an adjustment unit of a first mechanism that enables adjustment of the angle of the imaging device in an out-of-plane direction with respect to the installation surface; FIG. 10 is a diagram showing an example of an adjustment unit of a second mechanism that enables adjustment of the angle of the imaging device in an in-plane direction with respect to the installation surface; FIG. 10 is a diagram showing an example of an adjustment unit of a third mechanism that enables adjustment of the position of the imaging device along the installation surface; FIG. 10 is a diagram showing an example of a position indication unit that indicates the position of the imaging device; FIG. 4 is a diagram showing an example of a shutter section for covering an imaging device when the imaging device is not in use;

A door according to an embodiment is designed to authenticate a person who enters a room through the door or a person who exits the room through the door. A sensor is provided to detect the biometric information of the person entering and leaving the room from their finger. The biometric information detected by the sensor is compared with the registered biometric information of the user, and if the person entering and leaving the room is authenticated as the registered user, the lock can be unlocked and the door can be opened and closed. and This eliminates the need for a key for unlocking, thereby improving convenience for the user.

In order to improve the convenience of the user while ensuring the security of the door, it is necessary to reduce the false acceptance rate, in which a stranger is authenticated as the real person, and the false rejection rate, in which the real person cannot be authenticated as the real person, as close to 0 as possible. should be kept to a value. When the inventors of the present invention incorporated a sensor that detects a finger vein pattern as biometric information into a door handle and conducted an experiment to authenticate a person holding the handle, the false acceptance rate was 0%. The refusal rate was found to be relatively high. Approximately 70% of failed authentication cases are caused by misalignment of the finger and the sensor when gripping the handle, especially in the direction perpendicular to the longitudinal direction of the finger in the plane of the palm. , and misalignment in the direction perpendicular to the plane of the palm greatly affect the accuracy of authentication.

In order to solve such problems, the door of the present embodiment includes an adjustment section for adjusting the position or angle of the sensor with respect to the finger of the person entering or leaving the room when the person entering or leaving the room grips the operation section. By adjusting the position or angle of the sensor according to the finger of the person who enters and leaves the room, the adjustment unit can more accurately detect the biometric information of the person who enters and leaves the room, and can improve the accuracy of authentication.

In the present embodiment, an example will be described in which a captured image of a finger vein is taken as biometric information of a person entering and leaving a room, and the person entering and leaving the room is authenticated. Therefore, the sensor provided on the door of the present embodiment is an image pickup device for picking up an image of finger veins. In another example, biometric information for authenticating a person entering and leaving a room may be a fingerprint, a handprint, or any other biometric information that can authenticate an individual. .

FIG. 1 shows the configuration of a door 10 according to an embodiment. The door 10 is an example of a door body 12 that is openable and closable at an entrance of a building such as a house or an opening of a room entrance, and an operation part that a person who enters or leaves the room holds to open and close the door body 12. A handle 14, a lock part 16 for locking the door body 12, and an imaging device 20 for imaging the veins of the finger of the person who enters and leaves the room holding the handle 14 in order to authenticate the person entering and exiting the room holding the handle 14. , an authentication button 22 for requesting authentication by a person entering and leaving the room, and a control unit 40 for authenticating the person entering and leaving the room and unlocking the lock part 16 when the person entering and leaving the room is authenticated.

The imaging device 20 is installed on the back side of the handle 14 as seen from the person entering and leaving the room, and when the person entering and leaving the room grips the handle 14, images the veins of the index finger from the ventral side of the index finger. As a result, the imaging device 20 captures an image of the finger of the person entering and leaving the room, and the person entering and leaving the room can be authenticated without impairing the beauty of the door. The authentication button 22 is installed on the front side slightly above the imaging device 20 so that the person entering and leaving the room can press it with his or her thumb when holding the handle 14 .

When an entering/leaving person grips the handle 14 and presses the authentication button 22 with the thumb while the forefinger is in the field of view of the imaging device 20, the imaging device 20 takes an image of the vein of the forefinger and sends it to the control part 40.例文帳に追加The control unit 40 compares the imaged vein pattern of the person entering and leaving the room with the registered vein pattern of the user, and determines whether or not the vein pattern of the person entering and leaving the room matches the vein pattern of the user. . If it is determined that they match, the control unit 40 instructs the lock unit 16 to unlock. If it is determined that they do not match, the control unit 40 notifies the person entering and leaving the room that the authentication has failed by voice or display. A lock is provided so that the lock part 16 can be unlocked with a key when authentication fails in spite of being a valid user or when a user whose vein pattern has not yet been registered enters or leaves the room. A keyhole may be provided in the portion 16 .

Registration of the user's vein pattern may be performed by the control unit 40, or may be performed by a mobile terminal or the like used by the user. For example, when the authentication button 22 is operated in a predetermined manner, the control unit 40 executes a program for registering the user's vein pattern, once unlocks the lock unit 16 with a key, and so on. The user may be authenticated, the handle 14 may be gripped, the imaging device 20 may capture an image of the finger veins, and the captured image may be recorded in a memory or the like. Alternatively, an application executed on the mobile terminal may instruct the control unit 40 to capture an image of a finger vein using the imaging device 20 and register the captured image.

The controller 40 may be provided outside the door 10 . In this case, communication between the imaging device 20 of the door 10, the lock unit 16, and the like and the control unit 40 may be wired communication or wireless communication. A communication device that controls communication between the configuration of the door 10 and the controller 40 may be built into the door 10 .

In this embodiment, the following three mechanisms are proposed as mechanisms for adjusting the position or angle of the imaging device 20 . The first mechanism rotates the imaging device 20 in an out-of-plane direction with respect to the installation surface of the imaging device 20 . The second mechanism rotates the imaging device 20 in an in-plane direction with respect to the installation surface of the imaging device 20 . A third mechanism is to move the imaging device 20 along the installation surface of the imaging device 20 . Of these three mechanisms, only one mechanism may be provided, or any two or more mechanisms may be provided in combination.

[First mechanism: angle adjustment in the out-of-plane direction of the installation surface]
FIG. 2 shows an example of an adjustment unit of the first mechanism that enables adjustment of the angle of the imaging device 20 in an out-of-plane direction with respect to the installation surface. In the example shown in FIGS. 2(a) and 2(b), the imaging device 20 is integrated with a support base 21 for supporting the fingers of the person entering and leaving the room, and is attached to the handle 14 via a spring 30. Supported. When the finger of a person who enters and leaves the room is placed on the support base 21, the spring 30 expands and contracts due to the force pressing the finger against the support base 21, and the support base 21 is inclined so that the entire surface of the pad of the finger comes into contact with the support base 21.例文帳に追加For example, as shown in FIG. 2(a), when a person entering and leaving the room grips the handle 14 with their fingertips floating, the spring 30 on the first joint side is pushed by the finger and deforms so as to shrink. , the imaging device 20 is tilted according to the finger of the person entering and leaving the room. Also, as shown in FIG. 2(b), when the person entering and leaving the room grips the handle 14 with the first joint floating, the spring 30 on the fingertip side is pressed by the finger and deforms so as to shrink. , the imaging device 20 is tilted according to the finger of the person entering and leaving the room. As a result, the distance and angle between the imaging device 20 and the finger can be adjusted so that the veins of the finger of the person entering and leaving the room are within the field of view of the imaging device 20, and the distance and angle between the imaging device 20 and the finger can be adjusted. can be made the same at the time of registration and at the time of authentication, the accuracy of authentication can be improved.

In the example shown in FIG. 2C, the imaging device 20 and the lighting device 23 are provided on a support portion 31 supported by the handle 14 via frames 32 and 34 . A frame 32 is attached to the handle 14 . The frame 34 is rotatably provided around the shaft 33 and can be vertically rotated with respect to the frame 32 . The support portion 31 is rotatably provided around a shaft 35 and can be rotated in the left-right direction with respect to the frame 34 . When a person entering or leaving the room places his or her finger on the support portion 31, the support portion 31 can be turned vertically and horizontally, so that the imaging device 20 can be tilted according to the tilt of the finger. In this example, the imaging device 20 and the lighting device 23 are provided on the same support portion 31 so that they can rotate integrally, so that the imaging range of the imaging device 20 and the lighting range of the lighting device 23 can be interlocked. Since the imaging range of the imaging device 20 can be reliably illuminated, the accuracy of authentication can be improved.

The adjustment unit may be any mechanism capable of rotatably supporting the imaging device 20 in the out-of-plane direction with respect to the installation surface. For example, an elastic member such as sponge or rubber may be interposed between the imaging device 20 and the handle 14, and the imaging device 20 may be supported by the handle 14 via the elastic member, or may be electrically driven by a motor or the like. The imaging device 20 may be supported by the handle 14 by any member. In the latter case, the control unit 40 may detect the position or angle of the finger of the person entering or leaving the room, and drive the motor or the like so as to match the position or angle of the imaging device 20 with the position or angle of the finger of the person entering or leaving the room. .

[Second mechanism: angle adjustment in the in-plane direction of the installation surface]
FIG. 3 shows an example of an adjustment unit of the second mechanism that enables adjustment of the angle of the imaging device 20 in the in-plane direction with respect to the installation surface. 3A is a schematic cross-sectional view of the imaging device 20 and the adjustment unit, and FIGS. 3B and 3C are schematic plan views of the imaging device 20 and the adjustment unit. As shown in FIG. 3A, the imaging device 20 is integrated with a rotary support base 36 for supporting the fingers of the person entering and leaving the room, and is rotatably supported by the handle 14 via ball bearings 25. be done.

The rotary support table 36 has a guide surface 37 for placing a finger. When a person entering or leaving the room places his or her finger on the guide surface 37, the rotary support table 36 is moved so that the direction of the guide surface 37 matches the longitudinal direction of the finger. 36 is rotated in the in-plane direction, and the rotation stops when the finger is accommodated within the guide surface 37 . The guide surface 37 is preferably formed in a tapered shape such that the inner diameter becomes smaller from the near side to the far side, and may be formed in a U-shape or a V-shape, for example. As a result, the rotary support base 36 can be rotated in accordance with the longitudinal direction of the finger regardless of the thickness or shape of the finger of the person entering or leaving the room. The width of the guide surface 37 may be adjusted by a spring or the like according to the thickness and shape of the finger of the person entering and leaving the room. The end portion of the guide surface 37 on the side of the first joint of the finger may be inclined so as to become lower toward the end portion. As a result, the person entering and leaving the room can place his or her finger on the guide surface 37 with the first joint of the finger naturally bent. can be kept constant every time, the accuracy of authentication can be improved. When the handle 14 is installed on the right side of the door body 12, many people who enter and leave the room hold the handle 14 with their right hand. When installed on the left side of the main body 12, the left side of the guide surface 37 may be inclined. An inclination may be provided on both sides of the guide surface 37 .

The guide surface 37 of the rotary support base 36, which comes into contact with the fingers of the person entering and exiting the room, is preferably made of a smooth and smooth material such as polytetrafluoroethylene or polyacetal copolymer. As a result, it is possible to improve the usability of the person entering and leaving the room.

[Third mechanism: position adjustment along the installation surface]
FIG. 4 shows an example of the adjusting section of the third mechanism that allows the position of the imaging device 20 to be adjusted along the installation surface. An imaging device 20 provided with an adjustment section for the first or second mechanism or an adjustment section for the first and second mechanisms is slidably provided along rails 24 . As a result, even when the position at which the person entering and leaving the room grips the handle 14 differs depending on the height of the person entering and leaving the room, the position can be adjusted by moving the imaging device 20, and the accuracy of authentication can be improved. A plurality of imaging devices 20 may be provided, and in that case, the range of rails 24 in which each imaging device 20 can slide may be set. As will be described later, when a position indication unit for indicating the position of the imaging device 20 provided on the back surface of the handle 14 is provided on the front surface of the handle 14, the imaging device 20 and the position indication unit move in conjunction with each other. may be configured.

[Mechanism for indicating the position of the sensor]
FIG. 5 shows an example of a position indicator that indicates the position of the imaging device 20. As shown in FIG. As shown in FIG. 5(a), a groove 39 for placing the thumb when the person entering and exiting the room grips the handle 14, and a marker 38 for aligning the base of the thumb and index finger are provided on the front side of the handle 14. is provided. The groove 39 is provided so as to match the longitudinal shape of the thumb of the person entering and leaving the room when holding the handle 14 . The marker 38 is provided according to the shape of the base of the thumb and forefinger when the person entering and leaving the room grips the handle 14 . As shown in FIG. 5B, when the person entering and leaving the room aligns the thumb with the groove 39 and grips the handle 14 with the base of the thumb and forefinger aligned with the marker 38, the forefinger just aligns with the imaging device 20. . In this way, by providing the position indicating portion on the front side of the handle 14, even if the imaging device 20 is provided on the back side of the handle 14 and the position cannot be visually recognized by the person entering or leaving the room, the position of the imaging device 20 can be adjusted. Since the handle 14 can be grasped by the user, the accuracy of authentication can be improved.

In the example of FIG. 5, the marker 38 has a triangular shape that matches the shape of the base of the thumb and forefinger, but may be represented by curved lines or broken lines. A curve or straight line may be drawn around the handle 14 . In this case, the design, color, texture, shape, etc. of the upper and lower regions may be varied with the curved line or straight line as the boundary. As a result, it is possible to improve the design of the handle 14 and make it easier for the person entering and exiting the room to visually understand the position to be held. Concavities and convexities may be provided according to the shape of the marker, curve, or polygonal line. As a result, even when it is dark and it is difficult to visually recognize the position indicator, such as at the entrance door at night, the person entering and leaving the room is guided to grip the handle 14 at an appropriate position. Therefore, the accuracy of authentication can be improved.

The position indicating section can be combined with the adjustment section of any of the first to third mechanisms described above. As described above, when combined with the adjustment section of the third mechanism, it is preferable to make the position indication section movable along with the movement of the imaging device 20 .

[Anti-fouling shutter]
FIG. 6 shows an example of a shutter section for covering the imaging device 20 when the imaging device 20 is not used. 6A is a schematic perspective view of the configuration including the shutter section 52, and FIG. 6B is a sectional view of the configuration including the shutter section 52. FIG. As shown in FIG. 6A, the imaging device 20 is installed at the back of a cylindrical installation portion 50, and a front side of the installation portion 50 is provided so that the imaging device 20 and the outside world are separated from each other when the imaging device 20 is not in use. A shutter section 52 is provided for blocking.

A bottom portion 51 of the installation portion 50 is provided so as to be inclined toward the outside so that the depth side where the imaging device 20 is installed is high and the front side where the shutter portion 52 is installed is low. As a result, together with the fact that the installation portion 50 is formed in a cylindrical shape, even when the installation portion 50 is installed outdoors, moisture such as rainwater that has entered the interior of the installation portion 50 can be quickly removed. can be discharged.

The shutter part 52 may be pulled upward and opened. As a result, it is possible to reduce the situation where water accumulates in the portion that drives the shutter section 52 . The shutter section 52 may be installed tilted with respect to the vertical direction. As a result, it is possible to reduce the adhesion of moisture, dust, and the like to the shutter portion 52 . The atmospheric pressure may be adjusted so that the atmospheric pressure inside the shutter section 52 is higher than the atmospheric pressure outside. As a result, it is possible to reduce the intrusion of moisture, dust, etc. into the inside of the shutter section 52 .

The shutter part 52 may be opened only when it is detected that the person entering or leaving the room holds the handle 14 . The imaging device 20 may detect that the person entering or leaving the room has gripped the handle 14, or a human sensor 26 may be provided separately. In this case, the shutter section 52 uses infrared rays or infrared rays so that the finger of the person entering or leaving the room can be detected by the imaging device 20 or the human sensor 26 when the finger of the person entering or leaving the room approaches the outside of the shutter section 52 . It may be formed of a structure or material that transmits part or all of electromagnetic waves, such as radio waves, used by the imaging device 20 or the human sensor 26 to detect the fingers of people entering and leaving the room. The control unit 40 opens the shutter unit 52 when the imaging device 20 or the human sensor 26 detects the finger of the person entering or leaving the room. The control unit 40 does not need to open the shutter unit 52 when the position or angle of the finger of the person entering or leaving the room is deviated from the appropriate position or angle. After completing the authentication, the control unit 40 closes the shutter unit 52 . As a result, since the shutter portion 52 is opened only when necessary, it is possible to further reduce intrusion of moisture, dust, and the like.

The shutter part 52 may be formed of a structure or material that can block sunlight, especially the light of the setting sun. As a result, when the image capturing device 20 captures an image of the finger of a person who enters and leaves the room, it is possible to reduce the occurrence of halation due to the influence of sunlight and the veins of the finger not being captured properly.

The shutter section 52 can be combined with the adjusting section of any of the first to third mechanisms described above, and can also be combined with the position indicating section.

According to the above embodiment, it is possible to appropriately adjust the position or angle of the finger of the person entering or leaving the room and the position or angle of the sensor for detecting biometric information from the finger of the person entering or leaving the room. Therefore, the accuracy of authentication can be improved. In addition, since the authentication accuracy can be improved with a relatively inexpensive and simple configuration, high cost-effectiveness can be obtained. In addition, since it is possible to specify the person entering and leaving the room from the biometric information, it is possible to manage the time of entry and exit of the user, the state of being in the room, and the like. As a result, for example, parents can be notified that a child has returned home or gone out, and guardians, curators, and assistants can notify that a ward, curator, person in need of assistance, or a person requiring nursing care A person, a caregiver, etc. can be notified.
