Description

本発明は、帳票、帳面、カード、パスポート、航空券等を読み取る読取装置であって、透明な読取面上への異物の侵入の可能性を低減させ、操作者が特に意識してゴミ除去を行なわなくても、通常の操作で異物の除去ができる読取装置に関し、より詳細には、パスポート、航空券、カード等の重要な帳票を読取面に存在する異物で損傷される可能性を低減する読取装置に関する。   The present invention is a reading device for reading a form, a book, a card, a passport, an airline ticket, etc., which reduces the possibility of entry of foreign matter on a transparent reading surface, and removes dust with special attention from the operator. The present invention relates to a reading apparatus that can remove foreign matter by a normal operation without performing it, and more specifically, reduces the possibility that important forms such as passports, air tickets, and cards are damaged by foreign matter existing on the reading surface. The present invention relates to a reading device.

帳票を光学的に読み取って画像データとする帳票読取装置（スキャナ装置）が広く知られている。また、一部の帳票読取装置は、パスポート等の帳票、カード等の重要な印刷物の記録媒体に書かれている文字を撮像してセンターコンピュータが有するデータベースと通信を行なって帳票に組み込まれたＩＣチップの情報と印刷情報とを照合して真贋を判断するのに用いられる。 A form reading device (scanner device) that optically reads a form to obtain image data is widely known. In addition, some form reading devices are ICs that are incorporated in forms by imaging characters such as passports and images printed on recording media of important printed materials such as cards and communicating with a database held by the center computer. It is used to verify authenticity by comparing chip information with print information.

このような帳票読取装置では、その読取面に手で置かれた帳票やカード、あるいは帳票自動送り装置により読取面に送られてきた帳票やカードを読取面に載置して撮像し、この撮像した画像に対して解析を行なう。   In such a form reading device, a form or card placed on the reading surface by hand, or a form or card sent to the reading surface by the automatic form feeder is placed on the reading surface and imaged. Analysis is performed on the obtained image.

特にパスポート、航空券等を読取る読取装置は、入出国のカウンター、航空会社のカウンター等で用いられるが、いずれの場合も処理速度が要求されるため、一般のドキュメント読取装置であるＯＣＲ装置、コピー装置等が有する読取面の蓋を有せず、読み取り対象を手で押さえて帳票を撮像する。   In particular, reading devices that read passports, airline tickets, etc. are used at immigration counters, airline counters, etc., but in any case processing speed is required, so OCR devices that are general document reading devices, copy An image of a form is picked up by holding a reading object by hand without having a reading surface cover of the apparatus or the like.

このような帳票の読取装置に関し、例えば特許文献１には、電気的には画像信号からゴミを除去する認識方法が開示されている。また特許文献２には、スタンド型光学読取装置においてカールした原稿でも帯電手段で原稿を吸い付け、画像のゆがみを除去する光学読取装置が開示されている。また特許文献３にはスタンド型の読取装置において原稿の２辺をＬ字状の部材で位置決めし、帳票を読み取る装置が開示されている。
特開平６−２００８８号公報 特開２０００−３４１４８０号公報 特開２００５−１２４６７号公報 With regard to such a form reading apparatus, for example, Patent Document 1 discloses a recognition method for electrically removing dust from an image signal. Further, Patent Document 2 discloses an optical reading device that removes distortion of an image by sucking the original with a charging unit even on a curled original in a stand type optical reading device. Patent Document 3 discloses an apparatus for reading a form by positioning two sides of a document with an L-shaped member in a stand-type reading apparatus.
JP-A-6-20088 JP 2000-341480 A JP 2005-12467 A

上記各特許文献では、スタンド型の読取装置では外乱光によって読み取り不良が発生する可能性がつきまとい、さらに帳票、帳票のページが浮いてしまうと、浮きを押さえるために押さえた手が撮像を邪魔してしまう。
また、帳票を伏せて載置し、透明面な読取面を通して装置内部から読み取る装置にあっては、読取面上に残留したホチキスの針等でパスポート、カードそのものが傷つく可能性がある。また、ホチキスの針、あるいは書類の切り取り代である余白部の紙片が異物として読取面上に残り、読み取るべき文字、図形、あるいは写真等の撮影を邪魔して読取不良が発生する可能性がある。 In each of the above-mentioned patent documents, there is a possibility that a reading failure may occur due to ambient light in a stand-type reading device, and when a form or a page of a form is lifted, the hand pressed to suppress the floating disturbs imaging. End up.
In addition, in a device in which a form is placed face down and read from the inside of the device through a transparent reading surface, the passport and the card itself may be damaged by staples remaining on the reading surface. In addition, staples or a piece of paper in the blank space that is a margin for cutting out the document may remain on the reading surface as a foreign substance, which may cause reading failure due to obstructing photographing of characters, figures, photographs, etc. to be read. .

光学読取装置で読み取った信号を処理して認識率を上げることは上記特許文献１に示されているが、たとえ読取精度が向上しても、重要書類であるパスポート等が、読取作業時にホチキスの針等で傷がつき、以降、そのカード等の使用に支障をきたすことに対しては無力である。   Although it is shown in the above-mentioned Patent Document 1 to increase the recognition rate by processing the signal read by the optical reading device, even if the reading accuracy is improved, the passport which is an important document is not stapled during the reading operation. It is incapable of scratching with a needle or the like, and thereafter hindering the use of the card or the like.

また、特許文献２、特許文献３に示すように帳票の隣接する２辺を、読取装置の位置決め部材３２、３３に押し当てて位置決めする場合においては、２辺を突き当てて位置決めするため、位置決めの速さは向上して操作性はよいが、位置決め部材３２、３３があるために図８の手前から帳票を滑らせて位置決め部材３２、３３に帳票を突き当てるという通常の位置決め動作を行なう際、位置決め部材３２、３３で形成するコーナにホチキスの針等の異物が掃き寄せれるため、相当量が溜まってしまうと帳票を傷つける原因となるばかりでなく、読取面へはみ出してきたホチキスの針等が画像取得時に写りこみ、誤認識の原因となってしまう。   In addition, as shown in Patent Document 2 and Patent Document 3, when two adjacent sides of a form are pressed against the positioning members 32 and 33 of the reading apparatus and positioned, the two sides are abutted and positioned. However, since the positioning members 32 and 33 are present, the normal positioning operation of sliding the form from the front of FIG. 8 and hitting the form against the positioning members 32 and 33 is performed. Further, since foreign matters such as staples are swept up at the corners formed by the positioning members 32 and 33, if a considerable amount is accumulated, not only will it cause damage to the form, but also staples that protrude from the reading surface, etc. Will be captured during image acquisition, causing false recognition.

特に特許文献２に示すものは静電気で原稿を固定するため異物の付着が原因となる読取不良が起こる可能性が高い。   In particular, since the document shown in Patent Document 2 fixes a document with static electricity, there is a high possibility that a reading failure will occur due to adhesion of foreign matter.

また、特許文献２、特許文献３に示すものは外光に帳票等をさらして読み取るため、カメラのフラッシュ等の不用意な外光が画像取得面にあたると、読取面の照度差で読取が正常に行なわれにくいという問題があった。   In addition, since the documents shown in Patent Document 2 and Patent Document 3 are read by exposing a form or the like to external light, if inadvertent external light such as a camera flash hits the image acquisition surface, the reading is normal due to the difference in illuminance on the reading surface. There was a problem that it was difficult to be performed.

さらに、帳票が撮像時に撮像面から浮いてしまうと、印刷した内容が変形し、読み取り不良の原因となる。この「浮き」を押さえるため、位置決め部材に帳票を押さえるための逆Ｌ断面形状の部位を設けた場合は、これらの異物の除去作業は時間がかかってしまい、総合的な操作性が低下してしまう。   Furthermore, if the form is lifted from the imaging surface during imaging, the printed content is deformed, causing a reading failure. In order to suppress this “floating”, if the positioning member is provided with a portion having an inverted L cross-sectional shape for pressing the form, it takes time to remove these foreign substances, and the overall operability is reduced. End up.

本発明は、上述のごとき実情に鑑みてなされたもので、通常の読取時の操作で、異物の除去を図り、パスポート、カード等を保護し、さらにカード等の装脱をも容易にして操作者の負担を減らすことができるようにした読取装置を提供することを目的とするものである。   The present invention has been made in view of the above-mentioned circumstances, and is designed to remove foreign matter, protect passports, cards, etc., and easily remove and remove cards, etc., during normal reading operations. It is an object of the present invention to provide a reading apparatus that can reduce the burden on the user.

上記課題を解決するために、本発明の第１の技術手段は、帳票およびカードである記録媒体を光で読み取る読取手段を有する読取装置において、前記記録媒体を載置する読取面を有し、前記記録媒体の位置を決める位置決め部材と前記位置決め部材に設けたへの外光を遮光し、前記読取面と連なる異物除去排出口を有することを特徴としたものである。   In order to solve the above problems, a first technical means of the present invention has a reading surface on which the recording medium is placed in a reading device having a reading means for reading a recording medium that is a form and a card with light, A positioning member for determining the position of the recording medium and a foreign matter removal / discharge port connected to the reading surface by shielding external light from being provided on the positioning member.

第２の技術手段は、帳票およびカードである記録媒体を光で読み取る読取手段を有する読取装置において、前記記録媒体を載置する読取面を有し、前記記録媒体の位置を決める位置決め部材と前記読取面において前記位置決め部材と対向する位置に滑らかな凸部材と
を有するものであることを特徴としたものである。 According to a second technical means, in a reading apparatus having a reading means for reading a recording medium such as a form and a card with light, the reading means has a reading surface on which the recording medium is placed, and a positioning member that determines the position of the recording medium; The reading surface has a smooth convex member at a position facing the positioning member.

本発明によれば、帳票、帳面、カード、パスポート、航空券等を読み取る際、操作者が特に意識してゴミ除去を行なわなくても、通常の読み取り対象物を載置する操作の際に読み取り対象自体が異物をコーナへ押しやり、排出トンネルから除去ができる。   According to the present invention, when reading a form, a form, a card, a passport, an air ticket, etc., it is read at the time of an operation for placing a normal reading object even if the operator does not remove dust with particular attention. The object itself pushes foreign objects to the corner and can be removed from the discharge tunnel.

また、ガード部が透明な読取面上への異物の侵入の可能性を低減させるとともに、カード等の読取面からの装脱の際、カードとガラス面との間に隙間を作って取り出しやすくするため、カード等を読取面、上部ケース上を引きずることがなくなり、重要な帳票等を、読取面に存在する異物で損傷される可能性を低減した読取装置を提供することができる。   In addition, the guard part reduces the possibility of entry of foreign matter onto the transparent reading surface and creates a gap between the card and the glass surface for easy removal when the card is removed from the reading surface. Therefore, it is possible to provide a reading apparatus in which the card or the like is not dragged on the reading surface and the upper case, and the possibility of damaging important forms and the like with foreign substances existing on the reading surface can be provided.

本発明の一実施形態である読取装置を図１に示す。また、読取時の操作を図２を用いて説明する。読取装置１の筐体は上部ケース１６、下部ケース１５、位置決め部材４および透明な読取面２で構成されている。位置決め部材４は図１、図７に示すように逆Ｌ字状の凹みの奥に当接面１７が設けてあり、帳票を位置決め部材に押し当てると逆Ｌの奥まで入り込んで当接面１７で停止するため、操作者が帳票から若干手を離しても載置面から浮くことがないように構成されている。操作者は図２に示すように読み取り対象であるカード２０を位置決め部材４のコーナ２４へ押し当てる。読取装置はコーナ２４へ対象物が来たことを検知して照明１２を照射してカメラ１１で撮影し、回路１４により撮影した画像を所定の信号に変換して外部装置へ送出する。   A reading apparatus according to an embodiment of the present invention is shown in FIG. An operation during reading will be described with reference to FIG. The housing of the reading device 1 is composed of an upper case 16, a lower case 15, a positioning member 4, and a transparent reading surface 2. As shown in FIGS. 1 and 7, the positioning member 4 is provided with a contact surface 17 at the back of the inverted L-shaped recess. When the form is pressed against the positioning member, the contact surface 17 enters the back of the reverse L and enters the contact surface 17. Therefore, even if the operator releases his hand slightly from the form, the operator does not float from the placement surface. The operator presses the card 20 to be read against the corner 24 of the positioning member 4 as shown in FIG. The reading device detects that an object has arrived at the corner 24, illuminates the illumination 12, takes a picture with the camera 11, converts the image taken by the circuit 14 into a predetermined signal, and sends it to an external device.

この際に、撮影の最中はインジケータ３を点灯して操作者に撮影中であることを示す。操作者はこのインジケータの点灯中はカード等を動かしてはいけないことを知ることができる。   At this time, the indicator 3 is lit during shooting to indicate to the operator that shooting is in progress. The operator can know that the card or the like should not be moved while this indicator is lit.

撮影が終了するとインジケータが消灯するので、操作者はカードを取り出す操作をするが、平面度の高いガラスで構成された読取面からカードを取り出す際、カードを軽く抑えて読取り面上をガード部１９まで移動させると図６に示すようにカード２０と上部ケース１６との間に隙間ができる。この隙間を用いてカードを取り出せばカードが取り出しやすいため、その結果としてカードを傷めることがない。仮にガード部１９がない場合、上部ケース１６の端部までカードを移動させて取り出すことになるが、ガラスでできた硬度の高い読取面２と異なり樹脂あるいは板金で構成された上部ケース１６上にはホチキスの針等の異物が滞留しやすく、その分カードが損傷する可能性も上がってしまう。さらに樹脂であるカードと樹脂である上部ケースが摺動することもカード記録面によっては好ましくないが、ガード部１９によりこれらのリスクを低減することができる。   Since the indicator is turned off when the photographing is completed, the operator performs an operation of taking out the card. However, when taking out the card from the reading surface made of glass with high flatness, the card is lightly held and the guard unit 19 is placed on the reading surface. As shown in FIG. 6, a gap is formed between the card 20 and the upper case 16. If the card is taken out using this gap, the card can be easily taken out. As a result, the card is not damaged. If the guard portion 19 is not provided, the card is moved to the end of the upper case 16 and taken out. However, unlike the high-hardness reading surface 2 made of glass, the card is placed on the upper case 16 made of resin or sheet metal. In this case, foreign matter such as staples are likely to stay, and the possibility of damage to the card increases accordingly. Further, sliding of the resin card and the resin upper case is not preferable depending on the card recording surface, but these risks can be reduced by the guard unit 19.

また帳票を読取位置に置くとき上部ケースの上面を滑らしてコーナ２４に定置する操作が取られる可能性があるが、上部ケース上にホチキスの針等の異物が存在していた場合、この定置させる動作でホチキスの針等の異物を読取面２上に引き込んでしまうことが考えられるが、ガード部１９が帳票を押し上げ、ホチキスの針等の異物と帳票の間に隙間ができるためホチキスの針等の異物が読取面２まで引きずり込まれることはない。   In addition, when the form is placed at the reading position, there is a possibility that the upper surface of the upper case is slid and placed on the corner 24. If foreign matter such as a staple is present on the upper case, the upper case is placed. It is conceivable that a foreign object such as a staple is pulled onto the reading surface 2 by the operation, but the guard unit 19 pushes up the form, and a gap is formed between the staple and the foreign substance and the form, so that the staple The foreign matter is not dragged to the reading surface 2.

次に図３、図４を用いて読取面２に載ってしまった異物を除去する過程を説明する。本読取装置１は帳票としてパスポート、航空券、入出国管理カードに記載された文字、また必要に応じてパスポート等の帳票や航空券に組み込まれたＩＣチップを読み、電気信号に変換する。特にパスポートにおいては査証、入国管理カード等を紛失しないようにホチキスでパスポートに留めることが頻繁に行なわれる。出国審査等ではこれらの帳票を取る際に、ホチキスの針等の異物がパスポートから取れ、机に散乱することもある。また、帳票によってはあらかじめホチキスで留められることを考慮して留め代を設け、ミシン目を入れているものもある。このような帳票の留め代部分も異物として机上に散乱することもしばしばある。 また、各国においては最近の旅行者増加のため、入国審査、出国審査にかかわる人は多忙を極めている。このような環境の下では、読取面に異物が入らないようにするのは不可能である。   Next, the process of removing the foreign matter that has been placed on the reading surface 2 will be described with reference to FIGS. The reading device 1 reads a passport, air ticket, characters written on an immigration card, and a passport or other IC chip incorporated in the air ticket as necessary, and converts it into an electrical signal. Especially in passports, it is often done to staple visa, immigration card, etc. in staples so as not to be lost. When taking these forms at immigration, foreign objects such as staples can be taken from the passport and scattered on the desk. Some forms have perforations in consideration of being stapled in advance and have perforations. Often, such a margin portion of the form is scattered as a foreign object on the desk. In addition, due to the recent increase in tourists in each country, people involved in immigration and departure screening are extremely busy. Under such circumstances, it is impossible to prevent foreign matter from entering the reading surface.

図３は操作者が読取装置を見た視点で描かれているが、異物が読取面２に入った際、図３において奥に位置決め部材４があるため操作者は読取位置の手前から帳票を読取面に押し当て、読取面２上を滑らして位置決め部材４に押し当てる。位置決め部材４には図６の断面図に示す逆Ｌ字型断面の奥の当接面１７が設けてあり、帳票を位置決め部材４に押し当てている間の帳票の浮きを防止している。   Although FIG. 3 is drawn from the viewpoint of the operator looking at the reading device, when a foreign object enters the reading surface 2, since the positioning member 4 is in the back in FIG. 3, the operator puts the form from before the reading position. Press against the reading surface, slide on the reading surface 2 and press against the positioning member 4. The positioning member 4 is provided with a contact surface 17 at the back of the inverted L-shaped cross section shown in the cross-sectional view of FIG. 6 to prevent the form from floating while the form is pressed against the positioning member 4.

また読取面２に上を帳票２１あるいはカード２０を位置決めするために滑らす過程において、帳票２１の紙面の端部、あるいはカード２０の角で読取面２の上の異物を位置決め部材４のコーナ２４に押しやる動作になる。このためコーナ２４に設けた排出トンネル８からホチキスの針等の異物は帳票の位置決めのたびに順次排出される。   Further, in the process of sliding the reading surface 2 to position the form 21 or the card 20, foreign matter on the reading surface 2 at the edge of the paper surface of the form 21 or the corner of the card 20 is applied to the corner 24 of the positioning member 4. It becomes pushing action. Therefore, foreign matters such as staples are sequentially discharged from the discharge tunnel 8 provided at the corner 24 every time the form is positioned.

また図４に示すように、排出トンネル８は上部に位置決め部材４の一部で形成された遮光部５を有する。本読取装置は装置断面を示した図６より明らかなように、透明な読取面２を透過して読み取り対象を照明し撮像を行なうため外光が内部に入り込むのを嫌う。当接面１７の上部にある逆Ｌ形状は外光を防ぐ「ひさし」の役も兼ねている。   As shown in FIG. 4, the discharge tunnel 8 has a light shielding portion 5 formed by a part of the positioning member 4 at the top. As is apparent from FIG. 6 showing the cross section of the reading apparatus, the reading apparatus illuminates the reading object through the transparent reading surface 2 and performs imaging so that external light does not enter the inside. The inverted L shape at the top of the contact surface 17 also serves as a “eave” that prevents external light.

ここで排出トンネル８を上部を開放した「溝」で形成してしまうと、撮像素子の捜査開始の点である位置決め部のコーナに外光が入り、誤動作の原因となりかねない。遮光部５はこのような誤動作を防止するために有効である。コーナ２４は、どのような大きさの帳票が来た場合でも必ず読み取り対象が存在するべき位置であるため、電気的な処理の開始する基本の位置となるため、上述のように読取動作時の誤動作の原因になり易いためである。   If the discharge tunnel 8 is formed with a “groove” that is open at the top, external light may enter the corner of the positioning portion, which is the starting point of the image sensor search, and may cause malfunction. The light shielding unit 5 is effective for preventing such malfunction. Since the corner 24 is a position where the reading target should be present regardless of the size of the form, it is a basic position where the electrical processing starts. This is because it tends to cause malfunction.

また位置決め部材４は上部ケースから容易に着脱できる構成とすることがのぞましい。異物の排出トンネルが詰まった場合、容易にその清掃を行なうためである。   Further, it is preferable that the positioning member 4 be configured to be easily detachable from the upper case. This is because when the foreign matter discharge tunnel is clogged, it is easily cleaned.

次に読取面の周に設けたガード部１９について説明する。ガード部は読取面への異物の進入を防ぐとともに、読取面２からの帳票、カードの取り出しを容易にする効果を有する。具体的には凸の高さが０．５ｍｍ程度でも読取面への異物進入の防止、カードの取り出しに効果があることが実験で確認されている。また凸形状は図５に示すように高さ０．５ｍｍの凸の場合には半径０．５ｍｍの半円形の形状が好適であるが、半円形に限らず、先端が滑らかな山状のものであってもよい。また凸の高さもこれに限られない。   Next, the guard unit 19 provided around the reading surface will be described. The guard portion has an effect of preventing foreign matter from entering the reading surface and facilitating taking out the form and card from the reading surface 2. Specifically, it has been confirmed through experiments that even if the height of the convex is about 0.5 mm, it is effective in preventing foreign matter from entering the reading surface and taking out the card. In addition, as shown in FIG. 5, the convex shape is preferably a semicircular shape having a radius of 0.5 mm in the case of a convex having a height of 0.5 mm. It may be. The height of the convex is not limited to this.

次に本出願に係る読取装置１の構成を図１、図６および図７を用いて説明する。読取装置の筐体は上部ケース１６と下部ケース１５とより形成されているまた上部ケース１６には帳票、カードを読み取り位置に定置するための位置決め部材４と光学的にひずみの少ないガラスで作られた読取面２、及び読取面２の周囲で位置決め部材４が存在しない部分にガード部１９が設けられている。位置決め部材４の内側は逆Ｌ形状になっており逆Ｌ形状の奥に帳票、カード等、読み取る媒体を突き当てる当接面１７が設けてある。   Next, the configuration of the reading apparatus 1 according to the present application will be described with reference to FIGS. 1, 6, and 7. FIG. The housing of the reading device is formed of an upper case 16 and a lower case 15. The upper case 16 is made of a positioning member 4 for placing a form or a card at a reading position and a glass having little optical distortion. A guard portion 19 is provided in the reading surface 2 and a portion where the positioning member 4 does not exist around the reading surface 2. The inner side of the positioning member 4 has an inverted L shape, and an abutting surface 17 for abutting a medium to be read, such as a form or a card, is provided behind the inverted L shape.

読取装置の内部は読み取り対象を照明するＬＥＤが取り付けられた照明基板１２が読取面２の直下でＣＭＯＳ撮像素子１１の撮像光路から外れた側面に設けられている。図６では照明基板１２は１つだけ示してあるが、白色光以外に特定の色の光、あるいは赤外光、紫外光が必要であれば複数の照明基板を設けてもよい。   Inside the reading device, an illumination board 12 to which an LED for illuminating a reading target is attached is provided on a side surface directly below the reading surface 2 and off the imaging optical path of the CMOS image sensor 11. Although only one illumination board 12 is shown in FIG. 6, a plurality of illumination boards may be provided if light of a specific color, infrared light, or ultraviolet light is necessary in addition to white light.

撮像素子１１は装置全体の高さを低くするためミラー１３により光路を９０度曲げている。またアンテナ基板１０には読み取るべき帳票のＩＣチップと通信を行なうアンテナであるループコイルが形成されて読取面２の周囲に設置されている。またこのアンテナ基板１０には帳票を検出するための光源となるＬＥＤ、インジケータの光源となるＬＥＤ等も敷設されている。   The image sensor 11 has its optical path bent 90 degrees by a mirror 13 in order to reduce the height of the entire apparatus. A loop coil, which is an antenna for communicating with the IC chip of the form to be read, is formed on the antenna substrate 10 and installed around the reading surface 2. The antenna substrate 10 is also provided with an LED serving as a light source for detecting a form, an LED serving as an indicator light source, and the like.

下部ケース１５の底部には制御基板１４が設けられており。撮像素子１１の信号を加工する処理部、読取装置２全体の制御を行う制御部が設けられている。制御部で加工した撮像信号はインターフェース部に設けられたコネクターを介して上位装置に送られる。
図６に示すように撮像素子１１はミラー１３により光路を曲げて水平位置に取り付けられており、装置の使い勝手から、一番奥に位置決め部材４を設け、読取面２を跨いで上部ケース平坦部があり、この平坦部の下に撮像素子１１を設ける構成とするのが好ましい。このためコーナ２４からの光の漏れは撮像素子へ向けての漏れ光となり、撮像への影響が大きい、位置決め部材に設けた遮光部５はこのような漏れ光を防止するのに有効である。 A control board 14 is provided at the bottom of the lower case 15. A processing unit that processes the signal of the image sensor 11 and a control unit that controls the entire reading device 2 are provided. The imaging signal processed by the control unit is sent to the host device via a connector provided in the interface unit.
As shown in FIG. 6, the image pickup device 11 is mounted in a horizontal position by bending the optical path by a mirror 13. For convenience of the apparatus, the positioning member 4 is provided at the innermost position, and the upper case flat portion straddles the reading surface 2. It is preferable that the image sensor 11 is provided below the flat portion. For this reason, the light leakage from the corner 24 becomes light leakage toward the image pickup device, and the light shielding portion 5 provided on the positioning member, which has a large influence on the image pickup, is effective in preventing such light leakage.

したがって、本発明の実施の形態によれば通帳、パスポート等の帳票あるいは航空券を光学的に読み取る際、ホチキスの針等の異物で損傷することがなく安全に作業することができる。   Therefore, according to the embodiment of the present invention, when optically reading a form such as a passbook or a passport or an air ticket, it can be safely operated without being damaged by a foreign object such as a staple.

以上説明したように、本発明は、損傷を嫌う重要な帳票、帳面、カード、パスポート、航空券等を読み取る読取装置であって、透明な読取面上への異物の侵入可能性低減と操作者が特に意識してゴミ除去を行なわなくても、通常操作で異物の除去ができる読取装置に有効である。   As described above, the present invention is a reading device that reads important forms, forms, cards, passports, air tickets, etc. that do not like damage, and reduces the possibility of foreign objects entering the transparent reading surface. However, the present invention is effective for a reading apparatus that can remove foreign matters by a normal operation without removing dust with particular awareness.
