【発明の属する技術分野】
本発明は、一般的なセキュリティー分野で本人を確認するために用いられる指紋入力装置に関する。より詳しくは、指紋読取り面に指先を接触する際の姿勢に無理が無く、例えば高齢者でも楽に指紋入力が行える指紋入力装置に関する。
【0002】
【従来の技術】
建物の出入口等におけるセキュリティーを確保するために、指紋入力装置が用いられることがある。該入力装置の設置場所を節約するために、該装置は壁面に取り付ける形式が一般的である。壁面取り付け型では、入力者は手を持ち上げて、呼び鈴を押すような姿勢(図8)で指先を指紋読取り面に当て、指紋の入力を行う。読取り面は図7に示すように、鉛直方向からおよそ5〜45度(図7の角度c)くらい傾けてあることが多い。このように角度を付けることによって、入力者は指紋読取り面を容易に視認でき、指を当てる部分がよく見えるので好都合であり、一見したところ問題無いように思える。ところが実際に指を当てて入力してみるとそうではない。
【0003】
壁面取り付け型では、入力の際には指先だけが指紋読取り面に接触した状態になるような構造が大部分であるが、この姿勢では短時間であっても指先を静止して保持するのはかなりの困難や苦しさが感じられる場合がある。読取りを確実に行うには、呼び鈴を押すときのように適当にポンと押したり、一瞬タッチすれば良いというわけにはいかず、1秒ないしそれ以上の間ほぼ一定の圧力で指先の腹を読取り面に押しつけたままで静止し、扉等が開錠されるまで待っていなければならないのが普通である。実際にやってみると、楽な作業・姿勢ではないことがわかる。
【0004】
特に高齢者にとっては手を持ち上げて手のひらをそらせ、指を立てるようにする姿勢(図8の姿勢。この姿勢を本明細書で呼び鈴姿勢とも称する。)は相当な困難を伴うことがある。指紋入力時に手を保持する介助者が必要なことすらある。人口の高齢化が進行し、国を挙げてバリアフリーを推進している中で、高齢者の利用しにくいセキュリティーシステムが普及していることは問題である。
【0005】
特許文献1には指紋入力装置において、大人と子供の別無く指を常に面に一定の角度で当てられる装置が記載されている。指紋の読取り面のあるセンサがばね等で保持されており、指の圧力に追従して読取り面の角度が変化し、自然な姿勢で入力できるとされている。しかし本装置の読取り面は指を上方に立てて当てることが想定されており、前記した呼び鈴姿勢の問題がある。
【0006】
特許文献2には指紋入力装置において、指の姿勢の自由度が格段に高く、しかも高い照合精度の装置が記載されている。読取り面の周囲に指を載せる位置を案内する回転可能なガイド部材があり、指を載せる方向に自由度があって姿勢が楽であり且つその方向を検知して、入力された指紋画像を回転補正するものである。しかし本装置も結局呼び鈴姿勢で入力を行なっている。
【0007】
特許文献3は指紋ではなく掌紋を読取る装置に関するが、目的は同じく本人確認である。掌紋を撮像するために手のひらを当てる台(本文献の図面の図2の符号13)は、おおよそ水平のようであり、特に手のひらをそらせたり、指先を高くするような姿勢で入力するのでは無いと思われる。但し本文献には入力時の姿勢に関する記載は無く、入力しやすい姿勢についての示唆も無い。

【発明が解決しようとする課題】
中高齢者にも負担の少ない、楽な姿勢で指先を指紋読取り面に安定して当てることができる指紋入力装置を提供する。また指先を当てる正しい位置が容易にわかり、正確に入力できる指紋入力装置を提供する。
【0010】
【課題を解決するための手段】
本発明の指紋入力装置では、指紋を読取る面が指紋の入力者の方向に高くなる勾配を有し、その勾配の角度が水平面に対して3〜50度(図1の角度a)であることを特徴とする。
【0011】
指先を読取り面に当てるために手を前に出すとき、手をそらせて指先を手首よりも高くして保持することは肉体に負担をかける。しかし指先が手首よりも少し低くなるような姿勢なら自然であり、中高齢者も容易にその姿勢を保持して指紋入力ができる。本発明の指紋入力装置はその自然な姿勢のままで入力ができるように読取り面の奥の方が低くなっている。図2は本発明の装置で指紋入力をしている時の姿勢の一例を示す図である。
【0012】
また本発明の指紋入力装置の別の形態においては、指先を指紋の読取り面に当てたときの指の方向と、入力者に正対する方向とのなす角度(図4の角度b)が、平面図でみたときに5〜45度であることを特徴とする。指紋入力をしようとする人は、読取り面を視認する必要があるので、該読取り面がよく見えるように装置に正対するのが普通である。つまり顔のまっすぐ前の方向、即ち体の中心の前方に装置の指紋読取り部があるように立つのが普通である。この姿勢で手を前に出して装置に指先を当てる場合、手を自然に前に出すならば指先はまっすぐ前方に向くのではなく、肩から手に向かう方向に少し内側に向く(図4)。
【0013】
ゆえに読取り面がまっすぐ前方の向きであると、手をひねるようにして指を当てる必要があり、肉体に負担をかける。指紋読取り面が前記の角度の範囲であれば、指紋入力装置の正面に立って手を前に出すときの自然な楽な姿勢で指先を指紋読取り面に当てることができる。
【0014】
また本発明の指紋入力装置の別の形態においては、指先を指紋の読取り面に当てた状態において、手のひら及び又は手首を支持する台座を指紋読取り面の入力者の側に設ける。図5は台座3を利用して指紋入力をする一例を示す。装置に指先だけを当てて手を浮かすような姿勢は不安定であり、その姿勢を保つことは肉体に負担をかける。また手を浮かしているとどうしても動いたりふるえたりしやすく、従って読取り中に指先も動いて指紋入力が不正確になりやすい。指紋入力エラーになると、やり直しで苦しい姿勢をさらに続けねばならない。図5に示すように手のひらや手首を支える台座や枕状のものを指紋読取り面の入力者側に設置することにより、指先を読取り面に安定して当てることができ、またその姿勢を容易に保持して静止することができる。
【0015】
【発明の実施の形態】
(1)本発明の指紋入力装置においては、指紋を読取る面が指紋の入力者の方向に高くなる勾配を有し、該勾配の角度(図1の角度a)が水平面に対して3〜50度である。指先を当てるときは読取り面を目で確認できる方が良い。前記勾配の角度が小さいと読取り面の視認性は優れるが、指先の先端をそれだけ持ち上げるので姿勢はやや苦しくなる。角度を大きくすると指先はより下がった状態になり、姿勢は楽になるが読取り面を目で確認しにくくなる。以上を考慮して、角度は前記の3〜50度が適当であり、より好ましくは10〜35度である。
【0016】
また読取り面の高さは手を体の前に出して自然に触れるくらいの高さとするのが好ましい。一般成人では床面から読取り面までの高さは70〜120cmが好ましく、より好ましくは80〜115cmである。この値はそれぞれの入力装置において主として入力する人の身長に合わせて読取り面の高さを適宜調節できるようにするのが良い。入力者の身長に合わせて高さを調節できるようにしても良いし、高さの異なる複数の読取り部を設けても良い。
【0017】
(2)前記の勾配を大きくすると手や指の姿勢は楽になるが、読取り面の視認性は低下する。そこで指紋を読取る面の近傍に鏡を設置し、該鏡により入力者が指紋の読取り面および自分の指先を視認することができるようにすることができる。鏡の近傍に照明等を設置しても良い。図3は該鏡(図3の2)を設置する一例を示す。図3の矢印は入力者の眼の位置する方向である。
【0018】
(3)指紋入力装置において指先を正しい位置に当てることは簡単なようでいて意外に難しい。入力者は当然自分の指先の爪の側を見ながら指の腹を読取り面に当てる。ここで指の腹の中央部(指紋の渦の付近)を指紋を読取る面の中央に当てるのが正しい当て方であるが、入力者は爪の中央が指の腹の中央に対応すると錯覚しやすい。実際は爪の根元付近が指紋の中央部にあたるので、入力者から見たときに爪の根元付近が読取り面の中央部に位置するように指を当てねばならない。爪の中央が読取り面の中央にあたれば良いと勘違いして指先を当てると、指先の腹の先端付近しか読取り面に当たらず、指紋の読取りがうまくいかないことがある。
【0019】
このようなトラブルを防ぐ一つの方法として、本発明では指紋を読取る面の内部より光線を照射し、指先腹部の中央を当てる箇所が読取り面上に該光線による光点として表示される方法を開示する。例えば読取り面の中央に赤い光点があれば、それが指の腹の中央に当たるように指先を当てるべきことは容易にわかる。
光点を表示するための光線は、イメージセンサ等による指紋読取り中に邪魔になるなら読取り中は消しても良い。「指紋の渦の中心が赤い光点に当たるように指を当ててください」と表示すればより確実に入力をしてもらえる。
【0020】
(4)指先を指紋を読取る面の正しい位置に当てることを支援する別の方法として、本発明では指紋を読取る面の内部より画像を照射し、該画像が読取り面上において指先および爪の標準的な位置を表す方法を開示する。指先や爪の絵が読取り面に表示されていれば、当てる位置を迷う可能性は小さい。読み取りに支障がなければ読取り面に指先や爪の正しい位置を示す絵や画像を描いておくこともできる。
【0021】
(5)また指紋入力装置の前に立って指紋を入力しようとする場合に、前記した指紋を読取る面が指紋の入力者の方向に高くなる勾配を有する本発明の装置であっても、従来の壁掛け型の入力装置(呼び鈴姿勢で入力する)であっても、指先を該入力装置に当てるために手を前に出す自然の姿勢では、指はまっすぐに前方を向くのではなく、肩から手先へと向かう方向に、わずかに内側を向く。指をまっすぐに前に向けようとすると手を外側にひねるようにしなければならない。
【0022】
ゆえに指紋の読取り面は、手を前に出したときに指が自然に向く方向に合わせるのが好ましい。図4に示すように、その角度(図4の角度b)は5〜50度の範囲が好ましく、より好ましくは15〜40度である。
【0023】
ところで図4の構成では右利きの人にとっては楽であるが、左利きの人には大変入力しにくい。そこで左右どちらの利き腕の人でも容易に入力できるように、例えば読取り面をプリズムとして、右左どちらの手の指を当てる場合でも本発明の好ましい角度で一つのイメージセンサで指紋の読み取りが行えるようにすることもできる。もちろん左右の手それぞれに専用の読取り面を設けても良い。
【0024】
(6)また手のひらや手首を支持する台座を読取り面の近傍に設け、該台座で手のひらや手首を支持しながら指先を読取り面に当てるようにすれば姿勢も楽であり、指先を安定して読取り面に当てることができる。台座等は清潔のために抗菌性の材料を用いても良い。また指紋入力者がいない間は、台座や読取り面等を紫外線等の殺菌ランプで照射して衛生的に保つことも好ましい。
【0025】
図5は台座3を利用して指紋入力を行なう様子の一例を示す。図6は台座の形状の一例であり、かまぼこ型の例である。他に円座型、球面型、円筒型、角を丸めた直方体型等でも良い。図6において、台座の奥行き4は40〜120mm、高さ5は7〜30mm、そして幅6は60〜150mmが好ましい。
【0026】
セキュリティーのために、指紋以外に特許文献3に記載のように掌紋等を入力することも行なわれるが、該装置の設計において以上記述した本発明の指紋入力装置と同様の配慮が有効であることは言うまでもない。
【0027】
また指紋入力装置における指紋パターンの採取方法には、読取り面を通してイメージセンサ等により光学的に採取する方法の他に、読取り面に2次元に配置された静電容量センサにより非光学的に採取する方法などもある。本発明は入力者が自ら手または指を入力装置に差し出して入力を行なうものであれば、指紋パターンの採取方法の種類を問わず適用可能であり、その効果を発揮する。
【0028】
【発明の効果】
本発明の指紋入力装置は、手や腕に無理な姿勢を強いたり、肉体的に負担をかける姿勢を強いたりせず、楽に指紋入力を行なうことができる。また指先を当てる位置が容易にわかるように表示されており、迅速かつ正確に指紋入力ができる。特に中高齢以上の方が指紋入力する場合に、入力時における肉体的な負担を減らすことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a fingerprint input device used to identify a person in a general security field. More specifically, the present invention relates to a fingerprint input device that can easily input a fingerprint even by an elderly person without any difficulty when the fingertip contacts the fingerprint reading surface.
[0002]
[Prior art]
Fingerprint input devices are sometimes used to secure security at entrances and exits of buildings. In order to save the installation space of the input device, the device is generally mounted on a wall. In the wall-mounted type, the input person lifts his / her hand and puts his / her fingertip on the fingerprint reading surface in a posture (FIG. 8) in which the doorbell is pressed to input a fingerprint. As shown in FIG. 7, the reading surface is often inclined by about 5 to 45 degrees (angle c in FIG. 7) from the vertical direction. By providing such an angle, the input person can easily visually recognize the fingerprint reading surface, and the part to which the finger is put can be seen clearly, which is convenient, and it seems that there is no problem at first glance. However, it is not the case when inputting by actually touching the finger.
[0003]
In most wall-mounted configurations, only the fingertip contacts the fingerprint reading surface during input, but in this position the fingertip remains stationary even for a short time. There can be considerable difficulty and suffering. In order to perform reading reliably, it is not always possible to just press the button or touch it momentarily as when pressing the doorbell, but read the belly of the fingertip with almost constant pressure for 1 second or more Normally, the user must stand still while pressing against the surface and wait until the door or the like is unlocked. When you actually try it, you can see that it is not easy work and posture.
[0004]
Particularly for an elderly person, a posture in which the hand is lifted, the palm is distorted, and the finger is raised (the posture in FIG. 8; this posture is also referred to as a doorbell posture in this specification) may be accompanied by considerable difficulty. Sometimes you need an assistant to hold your hand during fingerprint input. With the aging of the population and the promotion of barrier-free services throughout the country, it is a problem that security systems that are difficult for the elderly to use have become widespread.
[0005]
Patent Literature 1 discloses a fingerprint input device in which a finger is constantly applied to a surface at a constant angle without distinction between an adult and a child. A sensor having a fingerprint reading surface is held by a spring or the like, and the angle of the reading surface changes according to the pressure of the finger, so that the input can be performed in a natural posture. However, it is assumed that the reading surface of the apparatus is placed with the finger upright, and there is a problem with the above described doorbell posture.
[0006]
Patent Document 2 discloses a fingerprint input device in which the degree of freedom of the posture of a finger is remarkably high and the matching accuracy is high. A rotatable guide member is provided around the reading surface to guide the position on which the finger is to be placed. There is a degree of freedom in the direction in which the finger is to be placed, the posture is easy, and the direction is detected, and the input fingerprint image is rotated. It is to be corrected. However, this apparatus also performs input in the doorbell posture after all.
[0007]
Patent Literature 3 relates to a device for reading a palm print instead of a fingerprint, but the purpose is also for identification. The platform on which the palm is applied to image the palm print (reference numeral 13 in FIG. 2 in the drawing of the present document) is almost horizontal, and the input is not particularly performed in such a manner as to deflect the palm or raise the fingertip. I think that the. However, this document does not describe a posture at the time of input and does not suggest a posture that is easy to input.

[Problems to be solved by the invention]
Provided is a fingerprint input device capable of stably applying a fingertip to a fingerprint reading surface in an easy posture with little burden on middle-aged and elderly people. In addition, the present invention provides a fingerprint input device capable of easily recognizing a correct position to be touched by a fingertip and inputting the input accurately.
[0010]
[Means for Solving the Problems]
In the fingerprint input device of the present invention, the surface on which the fingerprint is read has a gradient that increases in the direction of the fingerprint input person, and the angle of the gradient is 3 to 50 degrees with respect to the horizontal plane (angle a in FIG. 1). It is characterized by.
[0011]
When putting the hand forward to put the fingertip on the reading surface, deflecting and holding the fingertip higher than the wrist places a burden on the body. However, if the posture is such that the fingertip is slightly lower than the wrist, it is natural that middle-aged and elderly people can easily hold the posture and input a fingerprint. In the fingerprint input device of the present invention, the depth of the reading surface is lower so that the input can be performed in the natural posture. FIG. 2 is a view showing an example of a posture when fingerprint input is performed by the device of the present invention.
[0012]
In another embodiment of the fingerprint input device of the present invention, the angle (angle b in FIG. 4) between the direction of the finger when the fingertip is applied to the fingerprint reading surface and the direction directly facing the input person is a plane. It is characterized in that it is 5 to 45 degrees when viewed in the figure. Since a person who intends to input a fingerprint needs to visually recognize the reading surface, it is common to face the device so that the reading surface can be clearly seen. That is, it is common for the fingerprint reader of the device to stand in a direction in front of the face, that is, in front of the center of the body. In this posture, when the hand is put forward and the fingertip is applied to the device, if the hand is naturally put forward, the fingertip does not face straight forward but slightly inward in the direction from the shoulder to the hand (FIG. 4). .
[0013]
Therefore, if the reading surface is directed straight forward, it is necessary to twist the hand and put a finger on the reading surface, which places a burden on the body. When the fingerprint reading surface is within the above-mentioned angle range, the fingertip can be applied to the fingerprint reading surface in a natural and easy posture when standing in front of the fingerprint input device and putting out the hand to the front.
[0014]
In another form of the fingerprint input device of the present invention, a pedestal supporting a palm and / or a wrist is provided on the fingerprint reading surface on the side of the input person when the fingertip is in contact with the fingerprint reading surface. FIG. 5 shows an example of inputting a fingerprint using the pedestal 3. The posture of lifting the hand with only the fingertip on the device is unstable, and maintaining the posture places a burden on the body. In addition, if the hand is lifted, it is easy to move or shake, so that the fingertip also moves during reading, and the fingerprint input tends to be inaccurate. If you get a fingerprint input error, you have to keep trying again. As shown in FIG. 5, a pedestal or a pillow supporting the palm or the wrist is provided on the input side of the fingerprint reading surface so that the fingertip can be stably applied to the reading surface and the posture can be easily adjusted. Can hold and stand still.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
(1) In the fingerprint input device of the present invention, the surface from which the fingerprint is read has a gradient that becomes higher in the direction of the fingerprint input person, and the angle of the gradient (the angle a in FIG. 1) is 3 to 50 with respect to the horizontal plane. Degrees. When touching the fingertip, it is better to be able to visually check the reading surface. When the angle of the gradient is small, the readability of the reading surface is excellent, but the posture becomes slightly difficult because the tip of the fingertip is lifted by that much. When the angle is increased, the fingertip becomes lower, and the posture becomes easier, but it becomes difficult to visually confirm the reading surface. In consideration of the above, the angle is suitably 3 to 50 degrees, and more preferably 10 to 35 degrees.
[0016]
Further, it is preferable that the height of the reading surface is set so that the hand can be put in front of the body and naturally touched. For general adults, the height from the floor surface to the reading surface is preferably 70 to 120 cm, and more preferably 80 to 115 cm. This value is preferably set so that the height of the reading surface can be appropriately adjusted according to the height of the person who mainly inputs the data in each input device. The height may be adjusted according to the height of the input person, or a plurality of reading units having different heights may be provided.
[0017]
(2) When the gradient is increased, the posture of the hand or the finger becomes easier, but the visibility of the reading surface decreases. Therefore, a mirror can be provided near the surface from which the fingerprint is read so that the input person can visually recognize the fingerprint reading surface and his / her fingertip. Lighting or the like may be installed near the mirror. FIG. 3 shows an example of installing the mirror (2 in FIG. 3). The arrow in FIG. 3 is the direction in which the eye of the input person is located.
[0018]
(3) It is easy and surprisingly difficult to put a fingertip on a correct position in a fingerprint input device. The input person naturally touches the finger pad to the reading surface while looking at the side of the fingertip of the fingertip. Here, it is the correct way to apply the center of the finger pad (near the vortex of the fingerprint) to the center of the fingerprint reading surface. However, the input person has the illusion that the center of the nail corresponds to the center of the finger pad. Cheap. Actually, since the vicinity of the base of the nail corresponds to the center of the fingerprint, the finger must be applied so that the vicinity of the base of the nail is positioned at the center of the reading surface when viewed from the input person. If a fingertip is applied while misunderstanding that the center of the nail should be in the center of the reading surface, only the vicinity of the tip of the belly of the fingertip hits the reading surface, and the fingerprint reading may not be performed well.
[0019]
As one method for preventing such troubles, the present invention discloses a method of irradiating a light beam from the inside of a surface for reading a fingerprint and displaying a portion where the center of a fingertip is applied as a light spot by the light beam on the reading surface. I do. For example, if there is a red light spot in the center of the reading surface, it is easy to see that the fingertip should be applied so that it hits the center of the finger pad.
The light beam for displaying the light spot may be turned off during reading if it interferes with fingerprint reading by an image sensor or the like. If you display "Please put your finger so that the center of the fingerprint vortex hits the red light spot", you can get the input more reliably.
[0020]
(4) As another method of assisting the user to place the fingertip on the correct position of the fingerprint reading surface, the present invention irradiates an image from the inside of the fingerprint reading surface, and the image is standardized on the reading surface. Disclose a method of representing a general position. If a picture of a fingertip or a nail is displayed on the reading surface, there is little possibility that the position to be touched is lost. If there is no problem in reading, a picture or image indicating the correct position of the fingertip or the nail can be drawn on the reading surface.
[0021]
(5) Even when the device of the present invention has a gradient in which the surface for reading the fingerprint is higher in the direction of the fingerprint input person when trying to input the fingerprint while standing in front of the fingerprint input device, Even in the case of a wall-mounted input device (input in a doorbell posture), in a natural posture where the fingertip is put forward in order to put the fingertip on the input device, the finger does not face straight forward but from the shoulder. Point slightly inward, in the direction of your hand. If you aim your finger straight forward, you must twist your hand outward.
[0022]
Therefore, it is preferable to set the fingerprint reading surface in the direction in which the finger naturally faces when the hand is put forward. As shown in FIG. 4, the angle (angle b in FIG. 4) is preferably in the range of 5 to 50 degrees, and more preferably 15 to 40 degrees.
[0023]
By the way, the configuration of FIG. 4 is easy for a right-handed person, but very difficult for a left-handed person to input. Therefore, for example, the reading surface is a prism so that the fingerprint can be read by a single image sensor at a preferable angle according to the present invention even when the right or left finger is put on the reading surface, for example, so that a person with the dominant arm can input easily. You can also. Of course, a dedicated reading surface may be provided for each of the left and right hands.
[0024]
(6) If a pedestal supporting the palm or the wrist is provided near the reading surface, and the palm is applied to the reading surface while the palm or the wrist is supported by the pedestal, the posture is easy and the fingertip is stably maintained. Can be applied to the reading surface. The base may be made of an antibacterial material for cleanliness. It is also preferable that the pedestal, the reading surface, and the like be illuminated with a sterilizing lamp such as ultraviolet light to maintain hygiene while there is no fingerprint input person.
[0025]
FIG. 5 shows an example of how fingerprint input is performed using the pedestal 3. FIG. 6 shows an example of the shape of the pedestal, which is an example of a kamaboko type. Besides, a circular seat type, a spherical type, a cylindrical type, a rectangular parallelepiped type with rounded corners and the like may be used. 6, the depth 4 of the pedestal is preferably 40 to 120 mm, the height 5 is preferably 7 to 30 mm, and the width 6 is preferably 60 to 150 mm.
