Description

本発明は、指紋を画像として読み取る指紋読み取り手段を有する指紋照合ユニットの改良に関し、特に作業者の操作性、全体を小型軽量化した指紋照合ユニットに関する発明である。   The present invention relates to an improvement of a fingerprint collation unit having a fingerprint reading means for reading a fingerprint as an image, and particularly relates to a fingerprint collation unit in which the operability of an operator and the whole is reduced in size and weight.

一般的に本人確認を行う指紋検出センサは、本人がセンサ部分に指を押し当てる事が前提である為、本人から見やすい平面にセンサを配置している装置が多い（例えば特許文献１、２参照）。   In general, fingerprint detection sensors that perform identity verification are based on the premise that the person presses the finger against the sensor part, and thus there are many devices in which the sensor is arranged on a plane that is easy for the person to see (see, for example, Patent Documents 1 and 2). ).

特開２００３−７０７６９号公報（請求項１〜９）JP 2003-70769 A (Claims 1 to 9) 特開２００２−３７４３４６号公報（請求項１〜６）JP 2002-374346 A (Claims 1 to 6)

しかし、医療従事者が患者の確認を行う場合は、他人の指をセンサに当てる行為が、特許文献１、２に記載の装置では操作しづらい問題がある。例えば、麻酔下にあり、能動的に動くことができない患者を確認する場合、作業者は一方の手でセンサを持ち、もう一方の手で患者の指を持ち、それらを適当に接触させている状態でさらに検出を開始する命令を出す為のボタンを押さなければならないため、両手を使用し、且つ複雑な操作が必要となる。
また、患者側から指紋を検出している状態が見える事で作業者に指紋を検出されるという行為が、他人にプライバシーを預ける行為であると、不安を訴える事も考えられる。 However, when a medical staff checks a patient, there is a problem that the action of putting another person's finger on the sensor is difficult to operate in the devices described in Patent Documents 1 and 2. For example, when identifying a patient who is under anesthesia and cannot actively move, the operator holds the sensor in one hand and the patient's finger in the other hand, making them in proper contact Since a button for issuing a command to start further detection must be pressed in a state, both hands are used and a complicated operation is required.
In addition, it is conceivable that anxiety may be complained that the act of detecting the fingerprint by the worker by seeing the state of detecting the fingerprint from the patient side is an act of entrusting privacy to another person.

そこで本発明は以上の課題を解決するために鋭意検討を重ねた結果次の発明に到達した。

It is a use state figure which shows an example of a usage method.
The fingerprint verification unit 1 has a fingerprint reading unit 2 that attaches the upper housing 11 to the lower housing 21 via a joint 31 as illustrated in FIGS. 2 and 3 and reads a fingerprint image as illustrated in FIG. A conversion means 3 for converting a fingerprint image into fingerprint information, a fingerprint information storage means 4, a fingerprint information image collation means 5, and a communication means 10 with an external device, each of these means (the fingerprint reading means) 2, conversion means 3, storage means 4, collation means 5 and communication means 10) with external equipment are mounted on the upper housing 11 and / or the lower housing 21.
Furthermore, the fingerprint collation result notifying means 6 and the power supply unit 7 are mounted on the upper housing 11 and / or the lower housing 21.
Each of the means 2, 3, 4, 5, 6, 7, 10 may be attached to either the upper housing 11 and / or the lower housing 21 or may be attached separately. . In the form illustrated in FIGS. 2 and 3, the upper housing 11 is mainly movable, so that it is preferable that the upper housing 11 is mounted together.

For example, an optical fingerprint detection sensor or the like can be employed.
For example, the notification unit 6 displays a situation when a trouble occurs during reading of a fingerprint, and for example, a plurality of LED lamps can be employed. For example, the green lamp is lit when reading is successful, the red lamp is lit when reading is not successful, and the yellow lamp is lit when verification cannot be performed due to a device failure. The state can be notified. In addition, a method using a buzzer to notify the worker of the above condition with sound can be employed.
Any storage means 4 can be used as long as it can store fingerprint information. For example, a nonvolatile memory such as a flash ROM can be employed.

本発明の指紋照合ユニット１の形態は、図２及び図３に例示するように、上ハウジング１１を接合部３１を介して下ハウジング２１に装着し、指を上ハウジング１１と下ハウジング２１の間に挟み込む形態にしている。例えば医療行為を行う現場で患者から指紋を読み取る際に、自力で指紋読み取り手段２に指を押し当てられない状態の患者でも指を指紋読み取り手段２に対して読み取りやすい位置で押し当てることができるように、作業者が上下もしくは片方から上ハウジング１１と下ハウジング２１に外圧を加えることによって、間にある指を圧着できる形態をしている。
また、上ハウジングと下ハウジングで指を上下から圧着することにより指をセンサにあてる位置が固定され、毎回同じ条件で指紋情報を読み取ることができるため、登録時と照合時の指紋情報のばらつきが少なくなり、照合精度が向上する。
下ハウジング２１の中央部には、指を圧着しやすいように溝２２を形成している。溝２２は、上ハウジング１１に形成しても良いし、上ハウジング１１と下ハウジング２１の両方に形成しても良い。
接合部３１は、図２及び図３に例示するように形成される。すなわち、上ハウジング１１の下部端部に、軸（突起）３３を形成した***部３２を突設し、他方下ハウジング２１の上部端部に、軸受（溝）３５を形成した***部３４を突設し、前記軸３３を前記軸受３５に装着することにより、上ハウジング１１が回動できるように形成している。前記軸３３と前記軸受３５は着脱可能な形態に形成している。これにより上ハウジング１１と下ハウジング２１は簡単に分解でき、清掃も容易にできる。また上ハウジング１１に前記軸受３５を、下ハウジング２１に前記軸３３を形成しても良い。 As illustrated in FIGS. 2 and 3, the fingerprint verification unit 1 according to the present invention is configured such that the upper housing 11 is attached to the lower housing 21 via the joint portion 31, and the finger is placed between the upper housing 11 and the lower housing 21. The form is sandwiched between the two. For example, when a fingerprint is read from a patient at a site where medical practice is performed, even if the patient is in a state where the finger cannot be pressed against the fingerprint reading means 2 by himself, the finger can be pressed against the fingerprint reading means 2 at a position where it can be easily read. As described above, the operator can press the fingers between them by applying external pressure to the upper housing 11 and the lower housing 21 from the top or bottom or one side.
In addition, the position where the finger is applied to the sensor is fixed by crimping the finger from the top and bottom of the upper housing and the lower housing, and the fingerprint information can be read under the same conditions every time. The collation accuracy is improved.
A groove 22 is formed in the center of the lower housing 21 so that the finger can be easily crimped. The groove 22 may be formed in the upper housing 11 or may be formed in both the upper housing 11 and the lower housing 21.
The junction 31 is formed as illustrated in FIGS. 2 and 3. That is, a raised portion 32 having a shaft (protrusion) 33 is provided at the lower end portion of the upper housing 11, and a raised portion 34 having a bearing (groove) 35 is provided at the upper end portion of the lower housing 21. The upper housing 11 can be rotated by mounting the shaft 33 on the bearing 35. The shaft 33 and the bearing 35 are formed in a detachable form. Accordingly, the upper housing 11 and the lower housing 21 can be easily disassembled and can be easily cleaned. Further, the bearing 35 may be formed on the upper housing 11 and the shaft 33 may be formed on the lower housing 21.

さらに接合部３１は、図４及び図５に例示するように未使用時に上ハウジング１１と下ハウジング２１の間に指を自由に出し入れできる一定の間隔を保持する機構として保持部材３６を装着している。
保持部材３６は、作業者が上ハウジング１１及び／又は下ハウジング２１を閉じる力に対して反発するが、作業者が閉じる力に対して力が小さく、抵抗しきれずに上ハウジング１１及び下ハウジング２１は閉じることができる。しかし、作業者が力を加えなくなると反発する力によって上ハウジング１１及び下ハウジング２１を一定の間隔に戻すことができる。保持部材３６としてバネ、磁石、電気モーターなどを採用できる。
なお接合部３１の形態は、上ハウジング１１及び／又は下ハウジング２１が回動できる形態であれば図２及び図３に例示した形態以外でも、何でも採用することができる。
そのほかにも、上ハウジング１１及び／又は下ハウジング２１が上下動する形態を採用することができる。例えば、下ハウジングに垂直な軸を立て、上ハウジングが軸に沿って上下に摺動する機構を接合部３１としても良い。 Further, as illustrated in FIGS. 4 and 5, the joining portion 31 is provided with a holding member 36 as a mechanism for holding a certain distance between the upper housing 11 and the lower housing 21 so that fingers can be freely inserted and removed when not in use. Yes.
The holding member 36 is repelled by the force of the operator closing the upper housing 11 and / or the lower housing 21, but the force is small with respect to the force of the operator closing, and the upper housing 11 and the lower housing 21 are not fully resisted. Can be closed. However, the upper housing 11 and the lower housing 21 can be returned to a certain distance by a repulsive force when the operator stops applying force. As the holding member 36, a spring, a magnet, an electric motor, or the like can be used.
As long as the form of the joining part 31 can rotate the upper housing 11 and / or the lower housing 21, anything other than the form illustrated in FIGS. 2 and 3 can be adopted.
In addition, a form in which the upper housing 11 and / or the lower housing 21 moves up and down can be employed. For example, a mechanism in which an axis perpendicular to the lower housing is set up and the upper housing slides up and down along the axis may be used as the joint portion 31.

本発明の指紋照合ユニット１は、作業者が上ハウジング１１と下ハウジング２１で指を圧着したときに動作し、指紋の検出を行うことができるようにしている。
このために図４及び図５に例示するように下ハウジング２１に、スイッチ８と支持部材９を装着し、これら（スイッチ８と支持部材９）の上部に指紋読み取り手段２を配置している。指紋読み取り手段２は、上下動するように、支持部材９によって支えられている。支持部材９は、外力を受けて変形し、外力が除かれたときに元の形状に戻る性質を有するものであれば何でも良く、例えばバネ、ゴム等が採用される。
またスイッチ８と支持部材９は上ハウジング１１に装着し、上ハウジング１１の下部に、指紋読み取り手段２を配置しても良い。
支持部材９は、例えば図４及び図５に例示するように、非使用の状態では、指紋読み取り手段２を上に持ち上げており、指を挟んで上ハウジング１１及び／又は下ハウジング２１を閉めることにより、指紋読み取り手段２が指に押されて下（または上）に動くことによりスイッチ８が入り、指紋読み取り手段２を作動させ、指紋の検出を開始することができる。
本発明のスイッチ８と支持部材９は、これらの機能を備えたものであれば、図４及び図５に例示したもの以外でも何でも採用することができる。
また指を覆う形状をしていることは、患者に対して指紋を採取している行為に対する不安を抱かせないようにすることも目論んでいる。
本発明の指紋照合ユニット１は、小型軽量であり、通信手段１０を介してケーブルで接続または無線による通信で操作入力を行う携帯端末と共に携帯できる。通信手段１０は、例えば赤外線通信部材（ＩｒＤＡ）等を採用することができる。通信手段１０によって情報を送信あるいは受信する外部機器として例えば、記憶装置を内蔵しているパソコン、携帯型情報端末や、ハードディスクなどの情報記憶媒体などがある。 The fingerprint collation unit 1 of the present invention operates when an operator presses a finger between the upper housing 11 and the lower housing 21 so that the fingerprint can be detected.
For this purpose, as illustrated in FIGS. 4 and 5, the switch 8 and the support member 9 are mounted on the lower housing 21, and the fingerprint reading means 2 is arranged above these (the switch 8 and the support member 9). The fingerprint reading means 2 is supported by a support member 9 so as to move up and down. The support member 9 may be anything as long as it has a property of being deformed by an external force and returning to its original shape when the external force is removed. For example, a spring, rubber or the like is employed.
Further, the switch 8 and the support member 9 may be mounted on the upper housing 11, and the fingerprint reading unit 2 may be disposed below the upper housing 11.
For example, as illustrated in FIGS. 4 and 5, the support member 9 lifts the fingerprint reading means 2 upward when not in use, and closes the upper housing 11 and / or the lower housing 21 with the fingers sandwiched therebetween. Thus, the fingerprint reading means 2 is pushed by the finger and moved downward (or upward), so that the switch 8 is turned on, the fingerprint reading means 2 is activated, and the detection of the fingerprint can be started.
The switch 8 and the support member 9 of the present invention can adopt anything other than those illustrated in FIGS. 4 and 5 as long as they have these functions.
In addition, the shape covering the finger also aims to prevent the patient from being anxious about the act of collecting the fingerprint.
The fingerprint collation unit 1 of the present invention is small and light, and can be carried with a portable terminal that is connected via a communication means 10 with a cable or performs operation input by wireless communication. As the communication means 10, for example, an infrared communication member (IrDA) can be employed. Examples of external devices that transmit or receive information by the communication means 10 include a personal computer with a built-in storage device, a portable information terminal, and an information storage medium such as a hard disk.
