Description

情報入力装置Information input device
 本発明は、情報入力装置に関する。 The present invention relates to an information input device.
 ユーザの認証技術の1つとして、ユーザにパスワード入力を求め、あらかじめ登録したパスワードと照合してユーザの認証をおこなうことが広くおこなわれている。しかしながら、ユーザが記憶できる情報は、あまり多くはなく、金融機関などでは、4桁の数字がパスワードとして用いられている。簡単なパスワードは、個人情報から類推可能であったりして、必ずしも十分にセキュリティが確保されているとは言えない。 As one of user authentication technologies, it is widely performed to require a user to input a password and to authenticate the user by checking with a previously registered password. However, there is not much information that a user can memorize, and a 4-digit number is used as a password in financial institutions. Simple passwords can be inferred from personal information, and cannot be said to have sufficient security.
 そこで、個人を識別可能な生体情報を用いたユーザ認証が、パスワードを用いたユーザ認証に代わるものとして普及し始めている。たとえば、認証に利用可能とされる生体情報として、指紋、目の網膜や虹彩、顔、血管、DNA(Deoxyribo Nucleic Acid)などが知られている。 Therefore, user authentication using biometric information that can identify an individual is becoming popular as an alternative to user authentication using a password. For example, fingerprints, retinas and irises of eyes, faces, blood vessels, DNA (Deoxyribo Nucleic Acid), and the like are known as biometric information that can be used for authentication.
 ただし、生体情報を用いたユーザ認証は、未だパスワードを用いたユーザ認証に置き換わるものではなく、現在は、両者が併存する過渡的な状態にある。たとえば、銀行などの窓口は、暗証番号による認証をおこなうユーザ向けに、暗証番号(パスワード)の入力キーと、暗証番号の入力キーを外部から遮る遮蔽カバーを有する暗証番号入力装置を備える。また、銀行などの窓口は、たとえば、手のひらの静脈による認証をおこなうユーザ向けに、手のひらを撮像する非接触センサユニットと、手の手首を支持する前面ガイドを有する認証用撮像装置を備える。 However, user authentication using biometric information is not yet replaced by user authentication using a password, and is currently in a transitional state where both exist together. For example, a counter such as a bank includes a personal identification number input device having a personal identification number (password) input key and a shielding cover that shields the personal identification number input key from the outside for a user who authenticates with the personal identification number. In addition, a bank counter includes, for example, an authentication imaging device having a non-contact sensor unit that captures the palm and a front guide that supports the wrist of a user for a user who performs authentication using a palm vein.

The information input device 1 is required to be downsized in order to improve convenience in such a use environment. In addition, the information input device 1 may be placed on a counter table at the time of use, and may be put away at a predetermined storage position (for example, a locker, a drawer, a shelf, etc.) after use, and may be easily handled. It has been demanded.
 情報入力装置1は、暗証番号の入力と、手のひらの静脈パタンの入力と、磁気ストライプに記録された情報の入力と、IC(Integrated Circuit)カードに記録された情報の入力とをおこなうことができる。情報入力装置1は、着脱自在なガイド2を備える。情報入力装置1は、手のひらの静脈パタンの入力をおこなう場合にガイド2を装着し、手のひらの静脈パタンの入力をおこなわない場合にガイド2を取り外す。 The information input device 1 is capable of inputting a personal identification number, inputting a palm vein pattern, inputting information recorded on a magnetic stripe, and inputting information recorded on an IC (Integrated Circuit) card. . The information input device 1 includes a detachable guide 2. The information input device 1 attaches the guide 2 when inputting a palm vein pattern, and removes the guide 2 when not inputting a palm vein pattern.
 情報入力装置1は、大きな直方体状の箱体の一側に、小さな直方体状の箱体を合わせたような筺体10を有する。大小2つの直方体は、上面および底面の長手方向を奥行き方向とするとともに、上面および底面を略面一にして接続する。 The information input device 1 has a housing 10 in which a small rectangular parallelepiped box is combined with one side of a large rectangular parallelepiped box. The two large and small rectangular parallelepipeds are connected such that the longitudinal direction of the top surface and the bottom surface is the depth direction, and the top surface and the bottom surface are substantially flush.
 情報入力装置1は、筺体10の大きな箱体を形成する方に、静脈センサ4と、操作部11と、ICリーダライタ12を備える。情報入力装置1は、筺体10の小さな箱体を形成する方に、MS(Magnetic Stripe:磁気ストライプ)リーダ9を備える。 The information input device 1 includes a vein sensor 4, an operation unit 11, and an IC reader / writer 12 in the direction of forming a large box of the housing 10. The information input device 1 includes an MS (Magnetic Stripe) reader 9 on a side where a small box of the casing 10 is formed.
 静脈センサ4は、手のひらを撮像するイメージセンサ(たとえば、CMOS(Complementary Metal Oxide Semiconductor)センサ、CCD(Charge Coupled Device)センサなど)と、集光レンズと、被写体に照射して被写体との距離を測距するための複数の発光素子(LED:Light Emitting Diode)とを備える。 The vein sensor 4 is an image sensor for imaging the palm (for example, a CMOS (Complementary Metal Oxide Semiconductor) sensor, a CCD (Charge Coupled Device) sensor, etc.), a condensing lens, and a distance to the subject by irradiating the subject. It has a plurality of light emitting elements (LED: Light Emitting Diode) for distance.
 情報入力装置1は、筺体10の前面にICリーダライタ12にICカードを挿入する開口を備える。ICリーダライタ12は、ICカードが備えるICチップから所要の情報の読み出しをおこなったり、所要の情報の書き込みをおこなったりすることができる。たとえば、情報入力装置1は、ICリーダライタ12により照合用の生体情報(登録用テンプレート)をICチップに記録することができる。また、情報入力装置1は、ICリーダライタ12により照合用の生体情報をICチップから読み出すことができる。 The information input device 1 includes an opening for inserting an IC card into the IC reader / writer 12 on the front surface of the housing 10. The IC reader / writer 12 can read required information from an IC chip included in the IC card, and can write required information. For example, the information input apparatus 1 can record biometric information (registration template) for verification on the IC chip by the IC reader / writer 12. The information input device 1 can read biometric information for verification from the IC chip by the IC reader / writer 12.
 情報入力装置1は、ICカードを挿入する開口を正面にして筺体10の上面の手前側に、操作部11を備える。操作部11は、「0」から「9」までの数字キーと、訂正キーと、確定キーの合計12個の操作スイッチを4行3列に配置する。操作部11の奥手側には、表示部8を備える。表示部8は、4つのLEDからなり、操作部11で受け付けた暗証番号の入力桁数を表示する。 The information input device 1 includes an operation unit 11 on the front side of the upper surface of the housing 10 with an opening for inserting an IC card in front. The operation unit 11 arranges a total of 12 operation switches of “0” to “9”, a correction key, and a confirmation key in 4 rows and 3 columns. A display unit 8 is provided on the back side of the operation unit 11. The display unit 8 includes four LEDs, and displays the number of input digits of the password received by the operation unit 11.
 なお、表示部8は、LCD(Liquid Crystal Display:液晶ディスプレイ)などの表示装置であってもよい。また、表示部8がLCDである場合に、操作部11は、LCD上に設けられたタッチパネルなどであってもよい。 The display unit 8 may be a display device such as an LCD (Liquid Crystal Display). When the display unit 8 is an LCD, the operation unit 11 may be a touch panel provided on the LCD.
 情報入力装置1は、筺体10の上面に手首ガイド5を備える。手首ガイド5は、透明な樹脂製であり、前方起立壁13、側方起立壁7および手首支持部14を含んで構成される。 The information input device 1 includes a wrist guide 5 on the upper surface of the housing 10. The wrist guide 5 is made of a transparent resin and includes the front standing wall 13, the side standing wall 7, and the wrist support portion 14.
 手首ガイド5は、筺体10の上面であって、操作部11および表示部8の奥手側に、前方起立壁13を備える。前方起立壁13は、操作部11および表示部8と、静脈センサ4との間に設けられ、操作部11および表示部8と、静脈センサ4とを区画する。前方起立壁13は、所要の高さがあり、操作部11および表示部8を静脈センサ4の方向から観察できないようにする目隠しとして機能する。 The wrist guide 5 includes a front standing wall 13 on the upper surface of the housing 10 on the back side of the operation unit 11 and the display unit 8. The front standing wall 13 is provided between the operation unit 11, the display unit 8, and the vein sensor 4, and partitions the operation unit 11, the display unit 8, and the vein sensor 4. The front standing wall 13 has a required height and functions as a blindfold that prevents the operation unit 11 and the display unit 8 from being observed from the direction of the vein sensor 4.
 前方起立壁13は、静脈センサ4の方向から操作部11および表示部8を視認不能または視認困難に塗装されている。なお、前方起立壁13は、透過率の低い材質、屈折率の大きな形状、または遮蔽シールの貼付や凹凸加工などの表面処理によって、静脈センサ4の方向からの視認性を低下させるものであってもよい。 The front standing wall 13 is painted from the direction of the vein sensor 4 so that the operation unit 11 and the display unit 8 are not visible or difficult to view. Note that the front standing wall 13 is made of a material having a low transmittance, a shape having a large refractive index, or a surface treatment such as application of a shielding seal or uneven processing to reduce the visibility from the direction of the vein sensor 4. Also good.
 手首ガイド5は、静脈センサ4に翳される手の手首を支持する手首支持部14を、前方起立壁13の上端に備える。手首支持部14は、手首に合わせた曲面形状であり、手首の位置、傾きを規制して、手のひらを静脈センサ4の撮像範囲に的確に誘導する。また、手首支持部14は、前方起立壁13の上端から操作部11の方向に庇状にせり出す。これにより、手首支持部14は、静脈センサ4の方向の比較的高い視点から、操作部11および表示部8を目隠しする機能を有する。たとえば、手首ガイド5は、表示部8の直上に手首支持部14を備えることで、情報入力装置1の上方からの覗きこみに対しても表示部8を目隠しすることができる。これにより、金融機関の窓口で対面する係員が情報入力装置1の操作説明を身を乗り出しておこなうような場合であっても、顧客の入力内容や入力操作は、係員に対して目隠しされる。 The wrist guide 5 includes a wrist support portion 14 that supports the wrist of the hand that is crushed by the vein sensor 4 at the upper end of the front standing wall 13. The wrist support unit 14 has a curved surface shape that matches the wrist, and regulates the position and inclination of the wrist to accurately guide the palm to the imaging range of the vein sensor 4. Further, the wrist support portion 14 protrudes from the upper end of the front upright wall 13 in a hook shape in the direction of the operation portion 11. Thereby, the wrist support unit 14 has a function of blinding the operation unit 11 and the display unit 8 from a relatively high viewpoint in the direction of the vein sensor 4. For example, the wrist guide 5 includes the wrist support portion 14 immediately above the display portion 8, so that the display portion 8 can be blinded even when looking into the information input device 1 from above. As a result, even if a staff member who meets at the counter of the financial institution tries to explain the operation of the information input device 1, the customer's input contents and input operations are hidden from the staff member.
 このように、情報入力装置1は、手首支持部14が前方起立壁13の上端から操作部11の方向に庇状にせり出すことで、前方起立壁13の高さを抑制しながら操作部11および表示部8を目隠しする機能を向上している。 As described above, the information input device 1 is configured such that the wrist support portion 14 protrudes from the upper end of the front standing wall 13 in the shape of a hook in the direction of the operation portion 11, thereby suppressing the height of the front standing wall 13 and the operation portion 11 and The function of hiding the display unit 8 is improved.
 手首ガイド5は、前方起立壁13の両側に側方起立壁7を備える。側方起立壁7は、前方起立壁13と同様に透明な樹脂製であり、情報入力装置1の左右方向から操作部11および表示部8を視認不能または視認困難に塗装されている。したがって、前方起立壁13および側方起立壁7は、情報入力装置1の前方(手前側)および上方を開放したフード状の目隠しとなり、暗証番号の入力操作および入力内容を第三者が覗き見ることを防止する。 The wrist guide 5 includes side standing walls 7 on both sides of the front standing wall 13. The side upright wall 7 is made of a transparent resin like the front upright wall 13, and the operation unit 11 and the display unit 8 are painted from the left and right directions of the information input device 1 so that they cannot be seen or are difficult to see. Therefore, the front upright wall 13 and the side upright wall 7 serve as a hood-like blindfold with the front (front side) and the upper side of the information input device 1 opened, and a third party peeks at the password input operation and input contents. To prevent that.
 また、前方起立壁13および側方起立壁7は、一体成形により剛性が向上する。前方起立壁13と一体成形された側方起立壁7は、筺体10の上面から操作部11の方向に傾いて起立する前方起立壁13の倒れを防止する。これにより、情報入力装置1は、手首支持部14による手首支持の安定感を向上させている。 Further, the rigidity of the front upright wall 13 and the side upright wall 7 is improved by integral molding. The side upright wall 7 integrally formed with the front upright wall 13 prevents the front upright wall 13 rising from the upper surface of the housing 10 from being tilted in the direction of the operation unit 11. Thereby, the information input device 1 improves the sense of stability of wrist support by the wrist support portion 14.
 情報入力装置1は、筺体10の上面であって、手首支持部14の奥手側に指ガイド16を備える。指ガイド16は、矩形かつ板状であり、上端部で指を支持する。指ガイド16は、標準的な手のひら長(たとえば、110mm)だけ手首支持部14と離間して設けられる。 The information input device 1 includes a finger guide 16 on the upper surface of the housing 10 and on the back side of the wrist support portion 14. The finger guide 16 is rectangular and plate-shaped, and supports the finger at the upper end. The finger guide 16 is provided apart from the wrist support 14 by a standard palm length (for example, 110 mm).
 情報入力装置1は、筺体10の上面であって手首支持部14の奥手側に、静脈センサ4を備える。静脈センサ4は、筺体10の上面にある矩形状の開口から上方を臨む。静脈センサ4は、手首ガイド5と、筺体10の上面であって静脈センサ4の奥手側にある指ガイド16との間に設けられる。静脈センサ4は、筺体10の上面をセンシング(撮像)方向とし、手首ガイド5と指ガイド16に支持される手の手のひらの静脈像を撮像する。 The information input device 1 includes a vein sensor 4 on the upper surface of the housing 10 and on the back side of the wrist support portion 14. The vein sensor 4 faces upward from a rectangular opening on the upper surface of the housing 10. The vein sensor 4 is provided between the wrist guide 5 and a finger guide 16 on the back side of the vein sensor 4 on the upper surface of the housing 10. The vein sensor 4 sets the upper surface of the housing 10 in the sensing (imaging) direction and captures a vein image of the palm of the hand supported by the wrist guide 5 and the finger guide 16.
 すなわち、情報入力装置1は、操作部11と手首ガイド5、あるいは操作部11と手首ガイド5に加えて表示部8を含む操作入力領域29を備える。操作入力領域29は、手首ガイド5により操作部11、あるいは操作部11に加えて表示部8が操作者以外の第3者から目隠しされる。 That is, the information input device 1 includes an operation input area 29 including the display unit 8 in addition to the operation unit 11 and the wrist guide 5 or the operation unit 11 and the wrist guide 5. In the operation input area 29, the wrist guide 5 hides the operation unit 11 or the display unit 8 from the third party other than the operator in addition to the operation unit 11.
 また、情報入力装置1は、静脈センサ4と手首ガイド5、あるいは静脈センサ4と手首ガイド5に加えて指ガイド16を含む生体情報取得領域28を備える。生体情報取得領域28は、手首ガイド5により静脈センサ4がセンシング対象とする手を好適に支持する。 Further, the information input device 1 includes a biological information acquisition region 28 including a finger guide 16 in addition to the vein sensor 4 and the wrist guide 5 or the vein sensor 4 and the wrist guide 5. The biological information acquisition region 28 preferably supports the hand that the vein sensor 4 senses using the wrist guide 5.
 このように、情報入力装置1は、手首ガイド5を共有する形で操作入力領域29と生体情報取得領域28とを隣接して配置する。これにより、情報入力装置1は、小型化を実現し、狭いスペースでも設置を可能としている。 Thus, the information input device 1 arranges the operation input area 29 and the biological information acquisition area 28 adjacent to each other so as to share the wrist guide 5. As a result, the information input device 1 can be reduced in size and can be installed even in a narrow space.
 情報入力装置1は、コンピュータと接続する電源ケーブル6aおよび信号ケーブル6bと、筺体10の裏面側で接続する。電源ケーブル6aは、コンピュータと情報入力装置1とを、コンピュータから情報入力装置1に電源を供給可能に接続する。信号ケーブル6bは、コンピュータと情報入力装置1とを通信可能に接続する。電源ケーブル6aおよび信号ケーブル6bは、たとえば、USB(Universal Serial Bus:ユニバーサル・シリアル・バス)ケーブルとすることができる。 The information input device 1 is connected to the power cable 6a and the signal cable 6b connected to the computer on the back side of the housing 10. The power cable 6a connects the computer and the information input device 1 so that power can be supplied from the computer to the information input device 1. The signal cable 6b connects the computer and the information input device 1 so that they can communicate with each other. The power cable 6a and the signal cable 6b can be, for example, USB (Universal Serial Bus) cables.
 情報入力装置1は、筺体10の小さな箱体を形成する方に、MSリーダ9を備える。MSリーダ9は、上方にスリットを開放し、スリットの奥側から差込まれて手前側にスライド操作されたMSカードから情報を読み取る。スリットは、静脈センサ4の側方から操作部11の側方に至る長さを有し、筺体10の小さな箱体を長手方向に貫通する。情報入力装置1は、ガイド2を着脱自在とし、ガイド2を取り外した状態でのMSカードスライド操作を容易にしている。これにより、情報入力装置1は、MSカードスライド操作の操作者とガイド2との干渉を避けることができ、MSリーダ9を備えながらにして筺体10の小型化を可能にしている。 The information input device 1 includes an MS reader 9 on the side where a small box of the casing 10 is formed. The MS reader 9 opens the slit upward, and reads information from the MS card inserted from the back side of the slit and slid to the front side. The slit has a length from the side of the vein sensor 4 to the side of the operation unit 11 and penetrates a small box of the casing 10 in the longitudinal direction. The information input device 1 makes the guide 2 detachable and facilitates the MS card slide operation with the guide 2 removed. Thereby, the information input device 1 can avoid the interference between the operator of the MS card slide operation and the guide 2, and allows the housing 10 to be downsized while having the MS reader 9.
 ガイド2は、静脈センサ4が手のひらの静脈像を安定して取得可能なように、手を適切な姿勢に案内可能な形状をしている。ガイド2は、底面21を矩形として上方に向かって拡開した箱形(四角錐台)状であり、上方を開放した凹室22を有する。凹室22は、底面21の四辺から起立した前方壁19と、後方壁25と、2つの側方壁26、および底面21とから形成される。 The guide 2 has a shape capable of guiding the hand to an appropriate posture so that the vein sensor 4 can stably acquire a vein image of the palm. The guide 2 has a box shape (square pyramid) that is expanded upward with a bottom surface 21 as a rectangle, and has a concave chamber 22 that opens upward. The concave chamber 22 is formed by a front wall 19 erected from four sides of the bottom surface 21, a rear wall 25, two side walls 26, and the bottom surface 21.
 底面21は、中央部に窓部15を備え、前方壁19に沿ってスリット27を備える。窓部15は、ガイド2の装着時に静脈センサ4に対応する位置にあり、開口した領域内に静脈センサ4を内包する大きさを有する。 The bottom surface 21 includes a window portion 15 at the center and a slit 27 along the front wall 19. The window portion 15 is located at a position corresponding to the vein sensor 4 when the guide 2 is mounted, and has a size that encloses the vein sensor 4 in the opened region.
 スリット27は、ガイド2の装着時に指ガイド16に対応する位置にあり、指ガイド16を挿通可能な大きさと形状を有する。ガイド2は、指ガイド16をスリット27に挿通することにより、適正な装着がなされるように案内される。 The slit 27 is located at a position corresponding to the finger guide 16 when the guide 2 is mounted, and has a size and a shape through which the finger guide 16 can be inserted. The guide 2 is guided so as to be properly mounted by inserting the finger guide 16 through the slit 27.
 ガイド2は、開放端側となる4辺のうち3辺に鍔状の指支持部を備える。指支持部は、三指支持部17と、三指支持部17の両側に第1指/第5指支持部3を備える。三指支持部17は、静脈センサ4を挟んで手首ガイド5と対向する辺に位置し、第2指から第4指までの三指を支持する。第1指/第5指支持部3は、第1指または第5指のいずれか一方を支持する。三指支持部17は、底面21から起立する前方壁19の上端に位置する。第1指/第5指支持部3は、底面21から起立する側方壁26の上端に位置する。 The guide 2 includes a hook-shaped finger support portion on three sides of the four sides on the open end side. The finger support unit includes a three-finger support unit 17 and first and fifth finger support units 3 on both sides of the three-finger support unit 17. The three-finger support portion 17 is located on the side facing the wrist guide 5 with the vein sensor 4 interposed therebetween, and supports the three fingers from the second finger to the fourth finger. The first finger / fifth finger support unit 3 supports either the first finger or the fifth finger. The three-finger support portion 17 is located at the upper end of the front wall 19 that rises from the bottom surface 21. The first finger / fifth finger support 3 is located at the upper end of the side wall 26 that stands up from the bottom surface 21.
 三指支持部17と第1指/第5指支持部3は、所定の高さ(たとえば、5mm)の段差20を介して接続する。後方壁25の上端部とは、第1指/第5指支持部3は、所定の高さ(たとえば、5mm)の段差24を介して接続する。 The three-finger support part 17 and the first / fifth finger support part 3 are connected via a step 20 having a predetermined height (for example, 5 mm).

 ガイド2は、側面の奥手側下端に側方ガイド23を左右に一対備える。側方ガイド23は、舌状の起立壁であり、筺体10へのガイド2の装着時にガイド2の正位置への装着を案内する。また、ガイド2は、図示されない半球状の突起を底面21の裏面側に2つ備える。2つの半球状の突起は、筺体10の上面にある2つの位置決めガイド18とそれぞれ嵌合してガイド2を正位置に案内する。 The guide 2 is provided with a pair of side guides 23 on the left and right at the lower end on the back side. The side guide 23 is a tongue-like standing wall, and guides the mounting of the guide 2 to the normal position when the guide 2 is mounted on the housing 10. The guide 2 includes two hemispherical protrusions (not shown) on the back surface side of the bottom surface 21. The two hemispherical projections are respectively fitted with two positioning guides 18 on the upper surface of the housing 10 to guide the guide 2 to the normal position.
 このように、情報入力装置1は、筺体10にガイド2を装着することで、手首支持部14と、三指支持部17と、第1指/第5指支持部3とで手のひらを正位置に支持することができる。また、情報入力装置1は、ガイド2を不透過性の樹脂で形成することで、凹室22内への外乱光の侵入を制限し、手のひらの静脈像を好適に取得可能になる。 As described above, the information input device 1 attaches the guide 2 to the housing 10, so that the palm is placed in the normal position by the wrist support unit 14, the three-finger support unit 17, and the first / fifth finger support unit 3. Can be supported. In addition, the information input device 1 can suitably acquire a vein image of the palm by limiting the intrusion of disturbance light into the concave chamber 22 by forming the guide 2 with an impermeable resin.
 なお、情報入力装置1は、筺体10へのガイド2の装着を必須とせず、手首支持部14と、指ガイド16とで手のひらを支持することもできる。たとえば、外乱光の少ない環境下では、情報入力装置1は、筺体10へのガイド2の装着を省略して、手のひらの静脈像を簡便に取得することができる。 Note that the information input device 1 does not require the guide 2 to be attached to the housing 10, and can support the palm with the wrist support portion 14 and the finger guide 16. For example, in an environment with little disturbance light, the information input apparatus 1 can easily obtain a vein image of the palm by omitting the mounting of the guide 2 on the housing 10.
 次に、実施形態のガイド2が筺体10に装着されている状態、および情報入力装置1に手のひらが載置された時の様子について、図5から図7を用いて説明する。図5は、実施形態の情報入力装置の側面を示す図である。図6は、実施形態の情報入力装置における手のひらの静脈を撮像する時の様子を示す俯瞰図である。図7は、実施形態の情報入力装置における手のひらの静脈を撮像する時の様子を示す側面図である。なお、図5に図示する情報入力装置1は、ガイド2の着脱の理解を容易にするためガイド2を破線で表している。 Next, a state where the guide 2 of the embodiment is mounted on the housing 10 and a state when the palm is placed on the information input device 1 will be described with reference to FIGS. FIG. 5 is a diagram illustrating a side surface of the information input device according to the embodiment. FIG. 6 is a bird's-eye view showing a state when a palm vein is imaged in the information input device of the embodiment.
