JP 2011-38329 A Japanese Patent No. 4491442

  However, in the above-described conventional example, if the finger to be authenticated is strongly pressed against the root guide during imaging, the finger may become congested and the vein state may change.

  In particular, in the case of a baggage storage device having an unspecified number of users, there is a problem that the reliability of registration and verification for a registered template is low because the user cannot expect a high level of proficiency for vein authentication.

  The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide a luggage storage device that can improve operation reliability by increasing imaging accuracy. Another object of the present invention is to provide a finger vein authentication device that can be used in the luggage storage device.

  The finger vein authentication unit 3 captures the vein of the finger 4 to be authenticated and registers it as a template, and determines whether the authentication is correct or not by comparing the registered template with the image captured later. Although it is necessary to hold the finger 4 in a predetermined position, as described above, if the finger 4 is strongly applied to a guide or the like with priority given to holding the finger 4, the state of the vein may change. A certain amount of familiarity is required for accurate use of the vein authentication unit 3.

  In particular, the initial template registration operation needs to be cautious because it adversely affects the subsequent authentication operations. However, in luggage storage devices such as lockers and valuables storage boxes, an unspecified number of individuals who are not familiar with vein authentication. Since the registration operation by the user is performed, it is necessary to have a configuration with higher operational reliability than the case of the initial template registration for the ATM operation of the bank where the assistant who calls attention is used. There is.

The present invention has been made in view of the above points.
An appropriate number of luggage compartments 2 with lockable doors 1;
A finger vein authentication unit 3 that authenticates the authority to operate the door 1 of the luggage compartment 2;
The finger vein authentication unit 3 includes a fingertip support unit 5 that supports a fingertip on one side of the authentication range of the finger 4 to be authenticated, and supports a middle phalangeal joint portion 6 of the authentication target finger 4 on the opposite side. A finger joint joint support portion 7 is provided.

  In the present invention, by providing a metacarpophalangeal joint support part 7 for supporting the metacarpophalangeal joint part 6 at the base of the finger in addition to the fingertip support part 5, the finger 4 is connected to the fingertip support part 5 and the metacarpophalangeal joint. The joint support portion 7 is supported on both sides of the vein imaging region and is reliably held at a predetermined position.

  In addition, the metacarpophalangeal joint portion 6 is relatively less likely to cause blood congestion at the fingertips even if it is strongly compressed, and also belongs to the palm. Therefore, the imaging operation in this posture can be stabilized.

  In addition, when the appropriate part of the finger middle part is supported by the finger support part, the position of the finger 4 on the finger support part cannot be made constant, so the fingertip position is fixed in the butting shape. If the fingertip position is not constrained, the imaging position or the fingertip curving angle may not be constant. However, if the metacarpophalangeal joint 6 is constrained, Since the posture and position are generally determined, it is possible to achieve a highly reproducible holding posture.

Further, as described above, when the metacarpophalangeal joint portion 6 is supported, stable finger holding is possible.
The metacarpophalangeal joint support portion 7 is formed by an inclined surface that gradually increases toward the fingertip side,
The fingertip support portion 5 is arranged below the extended surface of the metacarpophalangeal joint support portion 7 and constitutes a luggage storage device that guides the imaging target finger 4 so as to guide the imaging target finger 4 into a convex curved shape during imaging. Since the target finger 4 can be held in a state in which the target finger 4 is guided in a curved shape having a substantially constant curvature and is released from the finger, stable image acquisition is possible.

In addition, the luggage storage device
The finger vein authentication unit 3 includes a finger vein authentication unit 8 in which a vein reading unit is incorporated in a case having the fingertip support unit 5 and a support block 9 forming a metacarpophalangeal joint support unit 7. It can be configured to be fixed to a support base 10 that supports four fingers other than four.

  The metacarpophalangeal joint support portion 7 can be formed integrally with the case of the finger vein authentication unit 8 provided with the imaging unit. However, when formed separately from the vein authentication device, it is relatively in contact with the fingertip. The metacarpophalangeal joint support portion 7 having a large area can be formed in a size that can be reliably supported.

Also,
The support base 10 is formed by an inclined surface that gradually decreases from the vicinity of the installation position of the metacarpophalangeal joint support portion 7 toward the front,
The operability is further improved by configuring a luggage storage device that leads to a slanted inclination posture in which the wrist is in the lowest position during imaging and the palm gradually increases as it goes to the finger 4 side.

Furthermore, the luggage storage device includes
A finger vein authentication unit 8 in which a vein reading unit is incorporated in a case provided with a fingertip support portion 5 at one end for supporting the fingertip of the finger 4 to be authenticated;
A finger vein authentication device having a support block 9 provided with a metacarpophalangeal joint support part 7 for supporting the metacarpophalangeal joint part 6 of the finger 4 to be authenticated on which the fingertip is supported by the fingertip support part 5 can be used.

  According to the present invention, it is possible to stably hold the finger to be authenticated at a predetermined position, so that the imaging accuracy is increased and the operation reliability can be increased.

  FIG. 1 shows an embodiment of the present invention configured as a rocker device for depositing valuables. The rocker device is formed by arranging a plurality of luggage storage chambers 2 in a housing 12. Each luggage storage chamber 2 is provided with a door 1 that is locked when not in use, and an operation unit 13 for unlocking the door 1 is disposed at the center of the housing 12.

  As shown in FIGS. 1B and 2, the operation unit 13 includes a display unit 14 for displaying operation instructions and the like, and a finger vein authentication unit 3 for authenticating the operation authority to the door 1. Become. The operation unit 13 is disposed at a position recessed from the outer peripheral wall of the housing 12 in order to prevent protrusion from the surface of the housing 12 and prevent disturbance light from entering the imaging unit described later or adversely affecting the appearance. .

  As shown in FIGS. 2 and 3, the finger vein authentication unit 3 fixes a finger vein authentication device 15 including a finger vein authentication unit 8 and a support block 9 to a support base 10 formed in the housing 12. It is formed. As the finger vein authentication unit 8, a well-known one in which an imaging means, a registration unit, and a verification unit (all not shown) are stored in a case. The imaging means determines a light source that irradiates near-infrared light or the like on the finger 4 to be authenticated, an imaging unit such as a CCD camera that captures a light-absorbed image of the irradiation light from the light source, a sharpness of an acquired image, In the case of imaging quality, it is configured to have an image management unit that performs patterning after cutting and the like, and the imaging system is a so-called transmission imaging system that irradiates the finger 4 to be authenticated from a surface other than the imaging region. Alternatively, a reflection type imaging method of irradiating the authentication site may be used.

  The registration unit stores the pattern data in a predetermined database so as to be searchable, and the collation unit searches the database for newly acquired pattern data, and enters an authentication establishment state when matching pattern data is searched. If no search is made, authentication is not established.

  In order to keep the position and state of the finger 4 to be authenticated relative to the photographing means constant and to improve the reproducibility of the shooting conditions, the case of the finger vein authentication unit 8 has a side edge of the finger 4 to be authenticated (in this example, the middle finger). And a planar U-shaped guide wall 16 surrounding the tip.

  The space between the inner walls of the guide wall 16 has an appropriate margin enough to absorb the individual difference in the thickness of the finger 4 and put the finger 4 to be authenticated, and the state in which the finger 4 to be authenticated is inserted Thus, the width is set so narrow that an excessive gap is generated between the finger 4 and the guide wall 16 and does not adversely affect photographing at the image pickup unit.

  Further, the distance between the outer walls of the guide walls 16 is such that the index finger and the ring finger adjacent to each other with the middle finger as the authentication target finger 4 placed between the guide walls 16 can easily fit the guide wall 16. Set to

  The tip of the guide wall 16 formed as described above is used as a finger abutting portion 16a, and further, a support base (finger tip support portion 5) that supports the fingertip in a state of abutting the tip against the finger abutting portion 16a from below. The fingertip detection sensor 17 is also arranged. In this example, an electrostatic sensor is used as the fingertip detection sensor 17.

  Further, the transparent cover 18 covering the photographing means is provided on the surface of the fingertip detection sensor 17 so that the finger 4 is not directly touched with the fingertip placed on the fingertip detection sensor 17 and the finger 4 extended to the open end side of the guide wall 16. And the support surface 16b formed at the open end of the guide wall 16 is disposed at a position lower than the plane to which the guide wall 16 belongs.

  As shown in FIG. 2, the finger vein authentication unit 8 is fixed to the support base 10 via a mounting bracket 10 a connected to the support base 10. As shown in FIG. 5, the fingertip detection sensor 17 of the finger vein authentication unit 8 is arranged at a slightly higher position with respect to the surface of the support base 10 in the fixed state to the support base 10, and the tip of the middle finger 4 Is placed on the fingertip detection sensor 17 and the remaining fingers are placed on the support base 10, only the middle finger 4 is guided to a raised middle and high posture.

  On the other hand, the support block 9 is arranged behind the finger vein authentication unit 8. As shown in FIG. 5A, the support block 9 is disposed at a position where the joint of the finger (the middle phalangeal joint 6) hits in a state where the fingertip is abutted against the finger abutting portion 16a.

  As shown in FIG. 3 (a), the tip of the middle finger is placed on the fingertip detection sensor 17 and the middle finger joint joint portion 6 is correctly placed on the support block 9. A guide illustration is given.

  As shown in FIGS. 3B and 5, the front end portion of the support base 10 is formed by an inclined surface whose height gradually decreases as it approaches the finger side, that is, the finger base. The surface of the block 9 is formed by an inclined surface having an inclination angle substantially coinciding with the inclined surface of the support base 10.

  Further, the support block 9 is set so that the surface to which the surface belongs is positioned higher than the fingertip detection sensor 17 of the finger vein authentication unit 8, and the metacarpophalangeal joint portion 6 is placed on the support block 9. When the fingertip is placed on the fingertip detection sensor 17, as shown in FIG. 5 (a), the middle finger is led into a slightly curved state that is convex upward, and the force is lost in combination with the above-described middle-high state. Guided to reading posture.

  Further, a capacitance sensor (finger detection sensor 11) is disposed at the center of the support block 9, and it can be detected that there is a finger on the support block 9.

  Therefore, in this embodiment, when the fingertip is placed on the fingertip detection sensor 17 in a state of being abutted against the finger abutting portion 16a and the metacarpophalangeal joint portion 6 is placed on the support block 9, the finger 4 to be authenticated is Since it is held on the image pickup means in a state where the eye is missing, a vein in a natural state can be imaged. In addition, when it is instructed to place the metacarpophalangeal joint portion 6 on the support block 9 that is inclined toward the front, it is pushed out as compared with the case where the metacarpophalangeal joint portion 6 is placed on the horizontal support block 9. Since resistance to movement in the direction is generated, it can be expected that variation in finger position is reduced from the mental effect of reducing the degree of freedom of the placement position on the support block 9.

  Furthermore, even when the user dislikes the instability and presses the metacarpophalangeal joint portion 6 onto the support block 9, congestion or the like is less likely to occur than when the intermediate portion of the fingertip is pressed. Therefore, it is possible to prevent a change in the state of the vein at the time of photographing, and it is possible to obtain a highly reproducible image.

  In the above description, the case where the finger vein authentication unit 3 is formed of the finger vein authentication unit 8 and the support block 9 has been shown. However, as shown in FIG. It is also possible to form the unit 8 integrally with the case.
