Description

画像読取装置および画像形成装置Image reader and image forming device
　本発明は、画像読取装置および画像形成装置に関し、特に、画像データの切出しを行なうための技術に関する。 The present invention relates to an image reading device and an image forming device, and more particularly to a technique for cutting out image data.
　コンタクトガラス上に載置された原稿を読取センサーにて光学的に読み取って画像データを生成する画像読取装置が、例えば複合機等の画像形成装置に備えられている。読取センサーとしては、ＣＣＤ（Charge Coupled Device）イメージセンサー又はＣＩＳ（Contact Image Sensor）が用いられている。 An image reading device that optically reads a document placed on a contact glass with a reading sensor to generate image data is provided in an image forming device such as a multifunction device. As the reading sensor, a CCD (Charge Coupled Device) image sensor or a CIS (Contact Image Sensor) is used.
　特許文献１には、読み取った画像データから原稿を示す一部の画像データだけを自動的に切り出すオートクロップ機能を備える画像読取装置が開示されている。この画像読取装置では、オートクロップ機能により、読み取った画像データにおけるエッジ位置を特定することで原稿の四辺（端辺）が検出され、検出した四辺に囲われた領域が画像データから切り出す領域として決定され、原稿の画像データだけが自動的に切り出される。 Patent Document 1 discloses an image reading device having an auto crop function that automatically cuts out only a part of image data indicating a manuscript from the read image data. In this image reader, the auto crop function detects the four sides (edges) of the document by specifying the edge position in the scanned image data, and the area surrounded by the detected four sides is determined as the area to be cut out from the image data. And only the image data of the original is automatically cut out.
　また、特許文献２には、ユーザーのまぶしさを軽減するために、コンタクトガラスを覆う原稿カバー（プラテンカバー）の開閉を検知するスイッチからの開検出信号に基づいて、原稿の読み取り時に原稿カバーが原稿載置台に対して開放された状態であることをユーザーに通知する画像読取装置が開示されている。 Further, in Patent Document 2, in order to reduce the glare of the user, the document cover is provided when the document is read, based on the open detection signal from the switch that detects the opening / closing of the document cover (platen cover) covering the contact glass. An image reading device for notifying a user that the document mounting table is open is disclosed.

　オートクロップ機能を利用する場合には、原稿カバー（プラテンカバー）が原稿載置台に対して開放された状態（すなわち、原稿カバーの開状態）で原稿の読取りが実行されることがある。例えば、読取センサーとしてＣＣＤイメージセンサーが用いられている画像読取装置では、ＣＣＤイメージセンサーは、原稿カバーの開状態における外乱光の影響が小さいので、オートクロップ機能による画像の切り出しを概ね正常に行うことができる。しかしながら、読取センサーとしてＣＩＳが用いられている画像読取装置では、ＣＩＳは、原稿カバーの開状態における外乱光の影響を大きく受けるため、原稿エッジの検出・切り出しに失敗し、原稿の誤検知・未検知が発生する場合がある。すなわち、オートクロップ機能による画像の切り出しを正常に行うことができない場合がある。 When using the auto crop function, the document may be read with the document cover (platen cover) open to the document mounting table (that is, the document cover is open). For example, in an image reader in which a CCD image sensor is used as a reading sensor, the CCD image sensor is less affected by ambient light when the document cover is open, so the image should be cut out normally by the auto crop function. Can be done. However, in an image reading device in which CIS is used as a reading sensor, CIS is greatly affected by ambient light when the document cover is open, so that detection / cutting of the document edge fails, and the document is erroneously detected / not detected. Detection may occur. That is, it may not be possible to cut out an image normally by the auto crop function.
　特許文献２に開示される技術は、原稿カバーが開状態であることをユーザーに通知する技術に過ぎず、ＣＩＳが用いられている画像読取装置において、原稿カバーが開状態のときにオートクロップが実行された場合の上記した問題を解決することはできない。 The technique disclosed in Patent Document 2 is merely a technique for notifying the user that the document cover is in the open state, and in an image reading device using CIS, auto cropping is performed when the document cover is in the open state. The above problem cannot be solved if it is executed.
　本発明は、上記の問題を解決するためになされたものであり、ＣＩＳが用いられている画像読取装置において、原稿カバーが開状態である場合に、オートクロップ機能による原稿の誤検知・未検知を防止することを目的とする。 The present invention has been made to solve the above problems, and in an image reader using CIS, when the document cover is in the open state, the auto crop function falsely detects or does not detect the document. The purpose is to prevent.
　本発明の一局面に係る画像読取装置は、原稿が載置される原稿載置面を有する原稿載置台と、前記原稿載置面に対して開閉可能に設けられ、前記原稿載置面に対して閉状態である場合に前記原稿載置面に載置されている前記原稿を覆う原稿カバーと、前記原稿カバーの開状態又は閉状態を検出する開閉検出部と、光源と、読取センサーとを有し、前記原稿載置面に載置されている原稿に向かって、主走査方向に沿って光を前記光源から出射させ、前記光源と前記読取センサーとを副走査方向に移動させながら、前記原稿を走査し、当該原稿からの反射光を前記読取センサーにて受光して前記原稿の画像を読み取る画像読取部と、前記画像読取部が備える前記読取センサーの種別情報を予め記憶する記憶部と、前記画像読取部による読み取りで得られた画像データから、前記原稿毎に独立した個別画像を切り出す個別画像切抜部と、ユーザーにより操作される操作部と、報知部と、制御部と、を備え、前記制御部は、前記操作部に対して前記個別画像切抜部による前記個別画像の切り出し指示がされている場合に、前記開閉検出部によって前記原稿カバーの開状態が検出され、かつ、前記記憶部に予め記憶された前記種別情報がコンタクトイメージセンサーを示す情報であると判定すると、前記原稿カバーが開状態であることを前記報知部により報知させ、前記画像読取部による前記原稿の画像の読み取りの実行を中断し、前記制御部が、前記開閉検出部によって前記原稿カバーの閉状態が検出されたと判定したときは、前記画像読取部に前記原稿の画像を読み取らせ、前記個別画像切抜部は、前記画像読取部による当該読み取りで得られた画像データから前記個別画像の切り出しを実行する、ものである。 The image reading device according to one aspect of the present invention is provided with a document mounting table having a document mounting surface on which a document is placed, and a document mounting surface that can be opened and closed with respect to the document mounting surface. A document cover that covers the document placed on the document mounting surface when the document cover is closed, an open / close detection unit that detects the open or closed state of the document cover, a light source, and a reading sensor. The image is emitted from the light source along the main scanning direction toward the document placed on the document mounting surface, and the light source and the reading sensor are moved in the sub-scanning direction. An image reading unit that scans a document and receives the reflected light from the document by the reading sensor to read the image of the document, and a storage unit that stores the type information of the reading sensor included in the image reading unit in advance. It is provided with an individual image cutting unit that cuts out an individual image independent for each document from the image data obtained by reading by the image reading unit, an operation unit operated by the user, a notification unit, and a control unit. When the operation unit is instructed to cut out the individual image by the individual image cutting unit, the control unit detects the open state of the document cover by the open / close detection unit and stores the image. When it is determined that the type information stored in advance in the unit is information indicating the contact image sensor, the notification unit notifies that the document cover is in the open state, and the image reading unit reads the image of the document. When the control unit determines that the closed state of the document cover is detected by the open / close detection unit, the image reading unit is made to read the image of the document, and the individual image cutting unit is used. , The individual image is cut out from the image data obtained by the reading by the image reading unit.
　また、本発明における画像形成装置は、上記の画像読取装置と、前記画像読取装置が読み取った画像を用紙に印刷する画像形成部と、を備える。 Further, the image forming apparatus in the present invention includes the above-mentioned image reading device and an image forming unit that prints an image read by the image reading device on paper.
　この発明によれば、ＣＩＳが用いられている画像読取装置において、原稿カバーが開状態である場合に、オートクロップ機能による原稿の誤検知・未検知を防止することができる。 According to the present invention, in an image reading device using CIS, when the document cover is in the open state, it is possible to prevent erroneous detection / non-detection of the document by the auto crop function.

As shown in FIG. 8, the guidance screen 68 includes the message 681 "Please specify on / off of the auto crop function." The guidance screen 68 includes, as soft keys, a key 682 for designating the on of the auto crop function and a key 683 for designating the off. Here, it is assumed that the user wants to turn on the auto crop function and presses the key 682. Then, it is assumed that the user presses the key 684 indicating "Next". When the control unit 101 detects that the key 684 is pressed after pressing the key 682 via the touch panel 15A after displaying the guidance screen 68, the control unit 101 guides the display unit 16 to instruct the display unit 16 to start scanning the card document. The guidance screen 70 shown in 9 is displayed. The guidance screen 70 includes a message 72 and, as soft keys, a reading start key 74 for inputting an instruction to start scanning the card document by the image reading unit 11. After displaying the guidance screen 70, the control unit 101 waits until the reading start key 74 is pressed (NO in S11).
　ユーザーは、案内画面７０を確認した後、図１に示すように、原稿カバー３２を開放して、予め定められている読取領域６におけるプラテンガラス３１の角部に、運転免許証５の角部の１つが重なるように、運転免許証５を載置する。このとき、ユーザーは、運転免許証５を、一方の面としての表面が読取り面となるように読取領域６に載置する。読取領域６は、例えば、プラテンガラス３１の角部の１つを含むＡ５サイズの領域である。 After confirming the guidance screen 70, the user opens the document cover 32, and as shown in FIG. 1, the corner portion of the driver's license 5 is formed on the corner portion of the platen glass 31 in the predetermined reading area 6. Place the driver's license 5 so that one of them overlaps. At this time, the user places the driver's license 5 on the reading area 6 so that the surface as one surface is the reading surface. The reading area 6 is, for example, an A5 size area including one of the corners of the platen glass 31.
　運転免許証５の載置後、ユーザーは、原稿カバー３２を開状態にしたままで、読取開始キー７４を押下したものとする。制御部１０１は、タッチパネル１５Ａを介して読取開始キー７４の押下を検出すると、カード原稿の読取りを開始する指示を受け付けたと判定し（Ｓ１１にてＹＥＳ）、オートクロップ機能がオンであるかオフであるかを判定する（Ｓ１２）。ここでは、制御部１０１は、タッチパネル１５Ａを介して、図８に示す案内画面６８のキー６８２の押下を検出しているので、オートクロップ機能がオンであると判定する（Ｓ１２にてＹＥＳ）。続いて、制御部１０１は、開閉検出部３３から出力される検出信号に基づいて、原稿カバー３２が開状態であるか否かを判定する（Ｓ１３）。 After the driver's license 5 is placed, it is assumed that the user presses the scanning start key 74 with the document cover 32 open. When the control unit 101 detects that the reading start key 74 is pressed via the touch panel 15A, it determines that the instruction to start reading the card document has been accepted (YES in S11), and the auto crop function is on or off. It is determined whether or not there is (S12). Here, since the control unit 101 detects the pressing of the key 682 of the guidance screen 68 shown in FIG. 8 via the touch panel 15A, it is determined that the auto crop function is on (YES in S12). Subsequently, the control unit 101 determines whether or not the document cover 32 is in the open state based on the detection signal output from the open / close detection unit 33 (S13).
　ここでは、原稿カバー３２が開状態であるので、制御部１０１は、原稿カバー３２が開状態であると判定し（Ｓ１３にてＹＥＳ）、読取センサーがＣＩＳであるか否かを判定する（Ｓ１４）。ここでは、ＨＤＤ１９に記憶された読取センサーの種別情報が「ＣＩＳ」を示す情報であるため、制御部１０１は、ＣＩＳであると判定する（Ｓ１４にてＹＥＳ）。 Here, since the document cover 32 is in the open state, the control unit 101 determines that the document cover 32 is in the open state (YES in S13), and determines whether or not the reading sensor is CIS (S14). ). Here, since the type information of the reading sensor stored in the HDD 19 is the information indicating “CIS”, the control unit 101 determines that it is CIS (YES in S14).
　制御部１０１は、表示部１６に、図１０に示す警告画面９０の表示をさせる（Ｓ１５）。警告画面９０は、「原稿カバーが開放されています！原稿カバーを閉じて下さい。」というメッセージ９０１と、「原稿カバーを閉じた後、読取開始を指示して下さい。」というメッセージ９０２と、ソフトキーとして、画像読取部１１によるカード原稿の読取りを開始する指示を入力するための読取開始キー９０３とを含む。警告画面９０の表示後、制御部１０１は、予め定められた期間である指定時間（例えば１分）が経過したか否かを判定し（Ｓ１６）、経過していなければ（Ｓ１６にてＮＯ）、原稿カバー３２が閉状態であるか否かを判定する（Ｓ１７）。制御部１０１は、原稿カバー３２が閉状態であれば（Ｓ１７にてＹＥＳ）、読取開始キー９０３が押下されると、画像読取部１１に対し、プラテンガラス３１の原稿載置面３１Ａ全体を読取らせて、原稿載置面３１Ａの全体に対応する画像を示す第１画像データ８０を生成させる（Ｓ１８）。このとき生成される第１画像データ８０は、図１１に示すように、カード原稿の一方の面である、運転免許証５の表面の画像を含む画像データである。 The control unit 101 causes the display unit 16 to display the warning screen 90 shown in FIG. 10 (S15). The warning screen 90 includes the message 901 "The document cover is open! Please close the document cover.", The message 902 "Please instruct to start scanning after closing the document cover.", And the software. The key includes a reading start key 903 for inputting an instruction to start reading the card document by the image reading unit 11. After displaying the warning screen 90, the control unit 101 determines whether or not a predetermined time (for example, 1 minute) has elapsed (S16), and if not (NO in S16). , It is determined whether or not the document cover 32 is in the closed state (S17). If the document cover 32 is in the closed state (YES in S17), the control unit 101 reads the entire document mounting surface 31A of the platen glass 31 to the image reading unit 11 when the reading start key 903 is pressed. The first image data 80 showing the image corresponding to the entire document mounting surface 31A is generated (S18). As shown in FIG. 11, the first image data 80 generated at this time is image data including an image of the front surface of the driver's license 5, which is one side of the card document.
　図１１は、画像読取部１１による原稿の読取りによって生成された第１画像データの一例を示す。図１１に示すように、第１画像データ８０は、運転免許証５の表面に対応する原稿部分８２と、原稿部分８２以外の部分とを含む。 FIG. 11 shows an example of the first image data generated by reading the original by the image reading unit 11. As shown in FIG. 11, the first image data 80 includes a manuscript portion 82 corresponding to the surface of the driver's license 5 and a portion other than the manuscript portion 82.
　例えば、原稿カバー３２が開状態である場合に画像読取部１１による原稿の読取りが実行されると、コンタクトイメージセンサー３８が外乱光による影響を受けてしまうので、原稿部分８２のエッジ８２Ａが検出できないことがある。ここでは、原稿カバー３２が閉状態である場合に画像読取部１１による原稿の読取りが実行されているので、コンタクトイメージセンサー３８が外乱光による影響を受けることがなく、画像読取部１１は、プラテンガラス３１における原稿が載置されている部分からの反射光を取得するため、第１画像データ８０における原稿部分８２のエッジ８２Ａが検出できる。したがって、原稿カバー３２が閉状態である場合には、個別画像切抜部１０２は、以下に説明するように、第１画像データ８０から原稿部分に対応する画像を示す第２画像データ８３を切出すオートクロップ機能を実行するように設定されている。 For example, if the document cover 32 is in the open state and the image reading unit 11 reads the document, the contact image sensor 38 is affected by the ambient light, so that the edge 82A of the document portion 82 cannot be detected. Sometimes. Here, since the document is read by the image reading unit 11 when the document cover 32 is closed, the contact image sensor 38 is not affected by ambient light, and the image reading unit 11 is platen. Since the reflected light from the portion of the glass 31 on which the original is placed is acquired, the edge 82A of the original portion 82 in the first image data 80 can be detected. Therefore, when the document cover 32 is in the closed state, the individual image cutting unit 102 cuts out the second image data 83 showing the image corresponding to the document portion from the first image data 80 as described below. It is set to execute the auto crop function.
　第１画像データ８０の生成後、個別画像切抜部１０２は、既知のエッジ検出技術を用いて、第１画像データ８０から、原稿部分８２のエッジ８２Ａを検出し、エッジ８２Ａで囲まれる原稿部分８２に対応する画像を示す第２画像データ８３を切出す（Ｓ１９）。 After the generation of the first image data 80, the individual image cropping unit 102 detects the edge 82A of the document portion 82 from the first image data 80 by using a known edge detection technique, and the document portion 82 surrounded by the edge 82A. The second image data 83 showing the image corresponding to is cut out (S19).
　図１２は、第２画像データの一例を示す。図１２に示すように、第２画像データ８３は、運転免許証５の表面に対応する原稿部分８２に対応する画像を示す画像データである。 FIG. 12 shows an example of the second image data. As shown in FIG. 12, the second image data 83 is image data showing an image corresponding to the manuscript portion 82 corresponding to the surface of the driver's license 5.
　そして、制御部１０１は、切出された第２画像データ８３を、ＨＤＤ１９の予め定められたユーザー用記憶領域に記憶させる（Ｓ２０）。 Then, the control unit 101 stores the cut out second image data 83 in a predetermined user storage area of the HDD 19 (S20).
　一方、制御部１０１は、Ｓ１７において原稿カバー３２が開状態のままで（Ｓ１７にてＮＯ）、Ｓ１６において指定時間が経過と判定した場合（Ｓ１６にてＹＥＳ）、オートクロップ機能を禁止する（Ｓ２１）。すなわち、制御部１０１は、オートクロップ機能をオフに変更し、個別画像切抜部１０２による第１画像データ８０からの、個別画像（原稿部分８２）に対応する第２画像データ８３の切出しを禁止する。 On the other hand, when the document cover 32 remains open in S17 (NO in S17) and the specified time is determined to have elapsed in S16 (YES in S16), the control unit 101 prohibits the auto crop function (S21). ). That is, the control unit 101 changes the auto crop function to off, and prohibits the individual image cropping unit 102 from cutting out the second image data 83 corresponding to the individual image (manuscript portion 82) from the first image data 80. ..
　制御部１０１は、Ｓ２１のあと、図１３に示すように、予め定められた読取サイズでの原稿の画像の読み取りを行う旨の確認画面９１を表示部１６に表示させる。 After S21, the control unit 101 causes the display unit 16 to display a confirmation screen 91 to the effect that the image of the original is read with a predetermined reading size, as shown in FIG.
　図１３は、読取サイズの確認画面の一例を示す図である。図１３に示すように、確認画面９１は、「オートクロップ機能が禁止されました。読取サイズはＡ５サイズでいいでしょうか？」というメッセージ９１１と、ソフトキーとして、画像読取部１１によるカード原稿の読取りを開始する指示を入力するための読取開始キー９１２と、カード原稿の読取りの中止を指示するための中止キー９１３を含む。制御部１０１は、確認画面９１の表示後、読取サイズの指示の有無を判定する（Ｓ２２）。 FIG. 13 is a diagram showing an example of a reading size confirmation screen. As shown in FIG. 13, on the confirmation screen 91, the message 911 "The auto crop function is prohibited. Is the reading size A5 size?" And the card document by the image reading unit 11 as a soft key. It includes a scanning start key 912 for inputting an instruction to start scanning and a stop key 913 for instructing to stop reading the card document. After displaying the confirmation screen 91, the control unit 101 determines whether or not there is an instruction for the reading size (S22).
　制御部１０１は、確認画面９１の読取開始キー９１２が押下されると、読取サイズの指示ありと判定し（Ｓ２２にてＹＥＳ）、画像読取部１１に対し、プラテンガラス３１の原稿載置面３１Ａにおける図１に示す読取領域６（ここではＡ５サイズの領域）を読取らせて、原稿載置面３１ＡにおけるＡ５サイズの読取領域６に対応する画像を示す第３画像データ８５を生成させる（Ｓ２３）。このとき生成される第３画像データ８５は、図１４に示すように、カード原稿の一方の面である、運転免許証５の表面の画像を含むＡ５サイズの画像データである。 When the reading start key 912 of the confirmation screen 91 is pressed, the control unit 101 determines that there is an instruction for the reading size (YES in S22), and the document placing surface 31A of the platen glass 31 with respect to the image reading unit 11. The reading area 6 (here, the A5 size area) shown in FIG. 1 is read, and the third image data 85 showing the image corresponding to the A5 size reading area 6 on the document mounting surface 31A is generated (S23). ). As shown in FIG. 14, the third image data 85 generated at this time is A5 size image data including an image of the front surface of the driver's license 5, which is one side of the card document.
　そして、制御部１０１は、第３画像データ８５を、ＨＤＤ１９の予め定められたユーザー用記憶領域に記憶させる（Ｓ２０）。なお、第３画像データ８５は切出しされていない画像であるので、制御部１０１は、第３画像データ８５に、切出しされていない画像であること示す第１付帯情報を対応付けて記憶させてもよい。 Then, the control unit 101 stores the third image data 85 in a predetermined user storage area of the HDD 19 (S20). Since the third image data 85 is an uncut image, the control unit 101 may store the third image data 85 in association with the first incidental information indicating that the image is not cut out. good.
　なお、制御部１０１が、読取センサーがＣＩＳでないと判定したときは（Ｓ１４にてＮＯ）、図５に示す処理は終了する。 When the control unit 101 determines that the reading sensor is not CIS (NO in S14), the process shown in FIG. 5 ends.
　一方、図８に示す案内画面６８のキー６８３が押下されて、読取開始された場合（Ｓ１１にてＹＥＳ）、制御部１０１は、Ｓ１２において、オートクロップ機能がオフであると判定し（Ｓ１２にてＮＯ）、読取サイズを、デフォルト値である例えばＡ４サイズに設定する（Ｓ２４）。そして、制御部１０１は、画像読取部１１に対し、プラテンガラス３１の原稿載置面３１Ａにおける図１に示す読取領域６（ここではＡ４サイズの領域）を読取らせて、原稿載置面３１ＡにおけるＡ４サイズの読取領域６に対応する画像を示す第４画像データ８７を生成させる（Ｓ２５）。このとき生成される第４画像データ８７は、図１５に示すように、カード原稿の一方の面である、運転免許証５の表面の画像を含むＡ４サイズの画像データである。 On the other hand, when the key 683 of the guidance screen 68 shown in FIG. 8 is pressed and reading is started (YES in S11), the control unit 101 determines in S12 that the auto crop function is off (in S12). NO), the reading size is set to the default value, for example, A4 size (S24). Then, the control unit 101 causes the image reading unit 11 to read the reading area 6 (here, the A4 size area) shown in FIG. 1 on the document placing surface 31A of the platen glass 31, and causes the document placing surface 31A. The fourth image data 87 showing the image corresponding to the A4 size reading area 6 in the above is generated (S25). As shown in FIG. 15, the fourth image data 87 generated at this time is A4 size image data including an image of the front surface of the driver's license 5, which is one side of the card document.
　そして、制御部１０１は、第４画像データ８７を、ＨＤＤ１９の予め定められたユーザー用記憶領域に記憶させる（Ｓ２０）。なお、第４画像データ８７は切出しされていない画像であるので、制御部１０１は、第４画像データ８７に、第１付帯情報を対応付けて記憶させてもよいし、切出し不許可を示す第２付帯情報を対応付けて記憶させてもよい。 Then, the control unit 101 stores the fourth image data 87 in a predetermined user storage area of the HDD 19 (S20). Since the fourth image data 87 is an uncut image, the control unit 101 may store the fourth image data 87 in association with the first incidental information, and may indicate that the cutout is not permitted. 2 Ancillary information may be associated and stored.
　制御部１０１は、Ｓ２０のあと、又は、図１３に示す確認画面９１の中止キー９１３が押下された場合（Ｓ２２にてＮＯ）、本処理を終了する。 The control unit 101 ends this process after S20 or when the stop key 913 of the confirmation screen 91 shown in FIG. 13 is pressed (NO in S22).
　上記の第１実施形態によれば、制御部１０１は、操作部１５に対して個別画像切抜部１０２による個別画像（図１１に示す原稿部分８２）の切り出し指示がされている場合に、開閉検出部３３によって原稿カバー３２の開状態が検出され、かつ、ＨＤＤ１９に予め記憶された種別情報がコンタクトイメージセンサーを示す情報であると判定すると、原稿カバー３２が開状態であることを表示部１６により報知させ、画像読取部１１による原稿の画像の読み取りの実行を中断する。このため、ＣＩＳ（コンタクトイメージセンサー）が用いられている画像読取装置２において、原稿カバー３２が開状態である場合に、個別画像切抜部１０２による個別画像（図１１に示す原稿部分８２）の切り出しを行わないので、個別画像切抜部１０２による個別画像（原稿部分８２）の切り出しの失敗を防止でき、オートクロップ機能による原稿の誤検知・未検知の発生を防止できる。 According to the first embodiment described above, the control unit 101 detects opening / closing when the operation unit 15 is instructed to cut out an individual image (manuscript portion 82 shown in FIG. 11) by the individual image cutting unit 102. When the open state of the document cover 32 is detected by the unit 33 and it is determined that the type information stored in advance in the HDD 19 is information indicating the contact image sensor, the display unit 16 indicates that the document cover 32 is in the open state. The notification is given, and the execution of the image reading of the original by the image reading unit 11 is interrupted. Therefore, in the image reading device 2 using the CIS (contact image sensor), when the document cover 32 is in the open state, the individual image cutout portion 102 cuts out the individual image (the document portion 82 shown in FIG. 11). Therefore, it is possible to prevent the individual image cutting unit 102 from failing to cut out the individual image (original portion 82), and it is possible to prevent the occurrence of erroneous detection / undetection of the original by the auto crop function.
　また、制御部１０１は、表示部１６による報知後から予め定められた期間（指定期間）において開閉検出部３３によって原稿カバー３２の閉状態が検出されると、画像読取部１１による原稿の画像の読み取りを実行させ、個別画像切抜部１０２による個別画像（原稿部分８２）の切り出しを実行させる。このため、ＣＩＳが用いられている画像読取装置２において、報知後の予め定められた期間内に原稿カバー３２が閉状態になった場合には、直ちに、原稿の画像の読み取りが実行され、個別画像切抜部１０２による個別画像（原稿部分８２）の切り出しが実行されるので、オートクロップ機能による画像の切り出しを迅速に行うことができる。また、ＣＩＳが用いられている画像読取装置２において、原稿カバー３２が閉状態であるときに、個別画像切抜部１０２による個別画像の切り出しが実行されるので、オートクロップ機能による原稿の誤検知・未検知を低減させることができ、第２画像データ８３を取得できる。 Further, when the control unit 101 detects the closed state of the document cover 32 by the open / close detection unit 33 within a predetermined period (designated period) after the notification by the display unit 16, the image reading unit 11 captures the image of the document. Scanning is executed, and the individual image (original portion 82) is cut out by the individual image cutting unit 102. Therefore, in the image reading device 2 in which the CIS is used, when the document cover 32 is closed within a predetermined period after notification, the image of the document is immediately read and individually. Since the individual image (original portion 82) is cut out by the image cutting portion 102, the image can be cut out quickly by the auto crop function. Further, in the image reading device 2 in which CIS is used, when the document cover 32 is in the closed state, the individual image is cut out by the individual image cutting unit 102, so that the auto crop function erroneously detects the document. Undetected can be reduced and the second image data 83 can be acquired.
　また、制御部１０１は、報知後の予め定められた期間（指定期間）において原稿カバー３２が開状態のままであれば、個別画像切抜部１０２による個別画像の切り出しを禁止させる。このため、ＣＩＳが用いられている画像読取装置２において、原稿カバー３２が開状態である場合に、オートクロップ機能による原稿の誤検知・未検知を防止することができる。 Further, if the document cover 32 remains in the open state for a predetermined period (designated period) after the notification, the control unit 101 prohibits the individual image cutting unit 102 from cutting out the individual image. Therefore, in the image reading device 2 in which CIS is used, when the document cover 32 is in the open state, it is possible to prevent erroneous detection / non-detection of the document by the auto crop function.
　また、制御部１０１は、個別画像切抜部１０２による個別画像の切り出しを禁止させた後、予め定められた読取サイズでの原稿の画像の読み取りを行う旨の表示を表示部１６に表示させ、操作部１５に対して前記予め定められた読取サイズ（例えばＡ５サイズ）での原稿の画像の読み取り指示があると、画像読取部１１による前記予め定められた読取サイズ（例えばＡ５サイズ）での原稿の画像の読み取りを実行させる。このため、オートクロップ機能による画像の切り出しを実行させるのではなく、予め定められた読取サイズでの原稿の画像の読み取りを行うことができる。これにより、ユーザーが確認した読取サイズの第３画像データ８５を取得することができる。 Further, the control unit 101 prohibits the individual image cutting unit 102 from cutting out the individual image, and then causes the display unit 16 to display a display indicating that the original image is read at a predetermined scanning size, and operates the operation unit 101. When the unit 15 is instructed to read the image of the original in the predetermined reading size (for example, A5 size), the image reading unit 11 instructs the image reading unit 11 to read the original in the predetermined reading size (for example, A5 size). Make the image read. Therefore, instead of cutting out the image by the auto crop function, it is possible to read the image of the original with a predetermined scanning size. As a result, the third image data 85 of the reading size confirmed by the user can be acquired.
　ところで、上述した制御プログラムは、読取センサーとしてＣＣＤイメージセンサーが装備された画像読取装置のＨＤＤにもインストールが可能である。上述した制御プログラムがＨＤＤにインストールされ、読取センサーとしてＣＣＤイメージセンサーが装備された画像読取装置は、ＨＤＤには、読取センサーの種別情報として「ＣＣＤ」を示す情報を記憶する。当該画像読取装置は、画像読取部の読取センサーがＣＩＳではなくＣＣＤイメージセンサーであること以外、画像読取装置２と同様の構成を有するものとする。ＣＣＤイメージセンサーが装備された当該画像読取装置の制御部が、図５にフローチャートで示す処理を行う場合、Ｓ１４では、ＨＤＤに記憶された読取センサーの種別情報が「ＣＣＤ」を示す情報であるため、制御部は、ＣＣＤであると判定することになる（Ｓ１４にてＮＯ）。原稿カバーが開状態であったとしても、ＣＣＤイメージセンサーは、原稿カバーの開状態における外乱光の影響が小さい。このため、制御部は、オートクロップ機能による個別画像の切出しを実行させる。制御部は、画像読取部に対し、プラテンガラスの原稿載置面全体を読取らせて、原稿載置面の全体に対応する画像を示す第１画像データ８０を生成させる。そして、個別画像切抜部は、第１画像データから個別画像（原稿部分）を示す第２画像データを切出す。そして、制御部は、第２画像データを、ＨＤＤのユーザー用記憶領域に記憶させる。すなわち、上述した制御プログラムは、上述した制御プログラムは、読取センサーとしてＣＩＳが装備された画像読取装置にも、読取センサーとしてＣＣＤイメージセンサーが装備された画像読取装置にも、適用が可能である。 By the way, the above-mentioned control program can also be installed in the HDD of an image reading device equipped with a CCD image sensor as a reading sensor. The image reading device in which the above-mentioned control program is installed in the HDD and equipped with a CCD image sensor as a reading sensor stores information indicating "CCD" as the type information of the reading sensor in the HDD. The image reading device has the same configuration as the image reading device 2 except that the reading sensor of the image reading unit is a CCD image sensor instead of a CIS. When the control unit of the image reading device equipped with the CCD image sensor performs the process shown in the flowchart in FIG. 5, in S14, the type information of the reading sensor stored in the HDD is the information indicating "CCD". , The control unit will determine that it is a CCD (NO in S14). Even if the document cover is in the open state, the CCD image sensor is less affected by ambient light when the document cover is in the open state. Therefore, the control unit causes the individual image to be cut out by the auto crop function. The control unit causes the image reading unit to read the entire platen glass document mounting surface and generate first image data 80 showing an image corresponding to the entire document mounting surface. Then, the individual image cutting unit cuts out the second image data indicating the individual image (manuscript portion) from the first image data. Then, the control unit stores the second image data in the user storage area of the HDD. That is, the above-mentioned control program can be applied to both an image reading device equipped with a CIS as a reading sensor and an image reading device equipped with a CCD image sensor as a reading sensor.
　次に、第２実施形態に係る画像読取装置２を含む画像形成装置１について、図面を用いて説明する。図１６及び図１７はそれぞれ、第２実施形態のカード原稿スキャン処理を示すフローチャートである。 Next, the image forming apparatus 1 including the image reading apparatus 2 according to the second embodiment will be described with reference to the drawings. 16 and 17 are flowcharts showing the card document scanning process of the second embodiment, respectively.
　第１実施形態では、ＣＩＳが用いられている画像読取装置２において、オートクロップ機能がオンに設定され、原稿カバー３２が開状態である場合に、個別画像切抜部１０２による個別画像の切り出しを行わないとしている。これに対して、第２実施形態では、原稿カバー３２が開状態であっても、画像読取部１１による原稿の画像の読み取りを実行させ、画像読取部１１による読み取りで得られた第１画像データ８０における原稿部分８２のエッジ８２Ａが検出可能である場合には、個別画像（原稿部分８２）の切り出しを行う点が、第１実施形態とは異なる。 In the first embodiment, in the image reading device 2 in which CIS is used, when the auto crop function is set to on and the document cover 32 is in the open state, the individual image is cut out by the individual image cutting unit 102. It is said that it is not. On the other hand, in the second embodiment, even when the document cover 32 is in the open state, the image of the document is read by the image reading unit 11, and the first image data obtained by reading by the image reading unit 11 is executed. When the edge 82A of the document portion 82 in 80 can be detected, the individual image (manuscript portion 82) is cut out, which is different from the first embodiment.
　第２実施形態では、第１実施形態の図５に示す処理と比べて、図１６に示すＳ１７にてＮＯの場合にＳ３１に進む点、図１７に示すＳ３１～Ｓ３３の処理が追加されている点が、第１実施形態とは異なる。このため、図１７に示すＳ３１～Ｓ３３について詳細に説明する。 In the second embodiment, as compared with the process shown in FIG. 5 of the first embodiment, a point where the process proceeds to S31 in the case of NO in S17 shown in FIG. 16 and the processes of S31 to S33 shown in FIG. 17 are added. The point is different from the first embodiment. Therefore, S31 to S33 shown in FIG. 17 will be described in detail.
　制御部１０１は、図１６に示すＳ１７において、原稿カバー３２が開状態であれば（Ｓ１７にてＮＯ）、表示部１６に、図１８に示す警告画面９２を規定時間（例えば１０秒）表示させ、読取実行指示の有無を判定する（図１７に示すＳ３１）。 In S17 shown in FIG. 16, if the document cover 32 is in the open state (NO in S17), the control unit 101 causes the display unit 16 to display the warning screen 92 shown in FIG. 18 for a specified time (for example, 10 seconds). , It is determined whether or not there is a read execution instruction (S31 shown in FIG. 17).
　警告画面９２は、「原稿カバーが開放された状態では、読取失敗になるおそれがあります！」というメッセージ９２１と、「原稿カバーを閉じずに、読取開始を指示しますか？」というメッセージ９２２と、ソフトキーとして、画像読取部１１によるカード原稿の読取りを開始する指示を入力するための読取開始キー９２３とを含む。警告画面９２の表示後、制御部１０１は、読取開始キー９２３が押下されると、読取実行指示ありと判定し（Ｓ３１にてＹＥＳ）、画像読取部１１に対し、プラテンガラス３１の原稿載置面３１Ａ全体を読取らせて、原稿載置面３１Ａの全体に対応する画像を示す第１画像データ８０を生成させる（Ｓ３２）。このとき生成される第１画像データ８０は、図１１に示すように、カード原稿の一方の面である、運転免許証５の表面の画像を含む画像データである。 The warning screen 92 includes a message 921 "If the document cover is open, scanning may fail!" And a message 922 "Do you want to instruct to start scanning without closing the document cover?" The soft key includes a reading start key 923 for inputting an instruction to start reading the card document by the image reading unit 11. After the warning screen 92 is displayed, when the reading start key 923 is pressed, the control unit 101 determines that there is a reading execution instruction (YES in S31), and places the original on the platen glass 31 on the image reading unit 11. The entire surface 31A is read to generate first image data 80 showing an image corresponding to the entire surface on which the document is placed (S32). As shown in FIG. 11, the first image data 80 generated at this time is image data including an image of the front surface of the driver's license 5, which is one side of the card document.
　一方、Ｓ３１において、制御部１０１は、読取開始キー９２３が押下されなかった場合、読取実行指示なしと判定し（Ｓ３１にてＮＯ）、予め定められた期間である指定時間（例えば１分）が経過したか否かを判定し（Ｓ１６）、経過していなければ（Ｓ１６にてＮＯ）、原稿カバー３２が閉状態であるか否かを判定する（Ｓ１７）。 On the other hand, in S31, when the reading start key 923 is not pressed, the control unit 101 determines that there is no reading execution instruction (NO in S31), and the designated time (for example, 1 minute) which is a predetermined period is set. It is determined whether or not it has elapsed (S16), and if it has not elapsed (NO in S16), it is determined whether or not the document cover 32 is in the closed state (S17).
　Ｓ３３において、制御部１０１は、個別画像切抜部１０２が第１画像データ８０からエッジを検出し、検出されたエッジによって囲まれる略矩形の領域を抽出された場合、原稿の輪郭を抽出可能であると判定する（Ｓ３３にてＹＥＳ）。 In S33, the control unit 101 can extract the outline of the original when the individual image cropping unit 102 detects an edge from the first image data 80 and extracts a substantially rectangular area surrounded by the detected edge. (YES in S33).
　この場合、第１画像データ８０から、エッジ８２Ａで囲まれる略矩形の原稿部分８２を抽出可能であるので、制御部１０１は、第１画像データから原稿の輪郭を抽出可能であると判定し（Ｓ３３にてＹＥＳ）、上記略矩形の領域に基づいて、読取られた原稿のサイズを決定する。 In this case, since the substantially rectangular original portion 82 surrounded by the edge 82A can be extracted from the first image data 80, the control unit 101 determines that the outline of the original can be extracted from the first image data ( YES in S33), the size of the scanned document is determined based on the above-mentioned substantially rectangular area.
　具体的には、制御部１０１はまず、検出されたエッジによって囲まれる略矩形の領域を抽出し、抽出した領域の主走査方向Ｘの長さを示す情報と、副走査方向Ｙの長さを示す情報とを取得する。制御部１０１は次いで、ＨＤＤ１９に記憶されている図４に示すサイズ情報４０から、取得された主走査方向Ｘの長さ及び副走査方向Ｙの長さに最も近い短辺の長さ及び長辺の長さを有するサイズを抽出し、抽出したサイズを原稿のサイズとして決定する。 Specifically, the control unit 101 first extracts a substantially rectangular area surrounded by the detected edges, and obtains information indicating the length of the extracted area in the main scanning direction X and the length of the sub-scanning direction Y. Get the information to show. Next, the control unit 101 has a short side length and a long side closest to the length of the main scanning direction X and the length of the sub-scanning direction Y acquired from the size information 40 shown in FIG. 4 stored in the HDD 19. The size having the length of is extracted, and the extracted size is determined as the size of the original.
　この場合、制御部１０１はまず、エッジ８２Ａで囲まれる原稿部分８２を抽出し、原稿部分８２の主走査方向Ｘの長さを示す「５４ｍｍ」という値と、副走査方向Ｙの長さを示す「８５．６ｍｍ」という値とを取得する。制御部１０１は次いで、サイズ情報４０から、取得された主走査方向Ｘの長さ及び副走査方向Ｙの長さと同じ短辺の長さ及び長辺の長さを有する運転免許証のサイズを抽出し、抽出した運転免許証のサイズを原稿のサイズとして決定する。 In this case, the control unit 101 first extracts the document portion 82 surrounded by the edge 82A, and indicates a value of "54 mm" indicating the length of the document portion 82 in the main scanning direction X and the length of the sub-scanning direction Y. The value of "85.6 mm" is acquired. The control unit 101 then extracts from the size information 40 the size of the driver's license having the same short-side length and long-side length as the acquired length of the main scanning direction X and the length of the sub-scanning direction Y. Then, the size of the extracted driver's license is determined as the size of the manuscript.
　個別画像切抜部１０２は、第１画像データ８０から、エッジ８２Ａで囲まれる原稿部分８２に対応する第２画像データ８３を切出す。制御部１０１は、切出された第２画像データ８３を、ＨＤＤ１９のユーザー用記憶領域に記憶させる。 The individual image cutting unit 102 cuts out the second image data 83 corresponding to the document portion 82 surrounded by the edge 82A from the first image data 80. The control unit 101 stores the cut out second image data 83 in the user storage area of the HDD 19.
　一方、Ｓ３３において、制御部１０１は、個別画像切抜部１０２が上記略矩形の領域を抽出できなかった場合には、原稿の輪郭を抽出不可能であると判定し（Ｓ３３にてＮＯ）、オートクロップ機能を禁止する（Ｓ２１）。 On the other hand, in S33, when the individual image cropping unit 102 cannot extract the substantially rectangular area, the control unit 101 determines that the outline of the original cannot be extracted (NO in S33), and auto. The crop function is prohibited (S21).
　上記の第２実施形態によれば、制御部１０１は、原稿カバー３２が開状態であることを表示部１６により報知させた後、開閉検出部３３によって原稿カバー３２の閉状態が検出されておらず、かつ、予め定められた期間（指定期間）において操作部１５に対して個別画像切抜部１０２による個別画像（原稿部分８２）の切り出し実行指示があると、画像読取部１１による原稿の画像の読み取りを実行させ、（ｉ）画像読取部１１による読み取りで得られた画像データ（第１画像データ８０）から原稿の輪郭を抽出可能である場合に、個別画像切抜部１０２による個別画像（原稿部分８２）の切り出しを実行させる。このため、ＣＩＳが用いられている画像読取装置２において、原稿カバー３２が開状態のときであっても、第１画像データ８０から原稿の輪郭を抽出可能であれば、オートクロップ機能による画像の切り出しを正常に行うことができる。一方、制御部１０１は、（ｉｉ）画像読取部１１による読み取りで得られた画像データ（第１画像データ８０）から原稿の輪郭を抽出不可能である場合に、個別画像切抜部１０２による個別画像（原稿部分８２）の切り出しを実行させない。このため、ＣＩＳが用いられている画像読取装置２において、原稿カバー３２が開状態のときに、画像データ（第１画像データ８０）から原稿の輪郭を抽出不可能であれば、個別画像切抜部１０２による個別画像（原稿部分８２）の切り出しを実行させないので、オートクロップ機能による原稿の誤検知・未検知を防止することができる。 According to the second embodiment described above, the control unit 101 notifies the display unit 16 that the document cover 32 is in the open state, and then the open / close detection unit 33 detects the closed state of the document cover 32. However, if the operation unit 15 is instructed to cut out the individual image (original part 82) by the individual image cutting unit 102 during a predetermined period (designated period), the image reading unit 11 will instruct the image reading unit 11 to cut out the original image. When scanning is executed and (i) the outline of the original can be extracted from the image data (first image data 80) obtained by scanning by the image scanning unit 11, the individual image (original portion) by the individual image cutting unit 102 82) Cut out is executed. Therefore, in the image reading device 2 in which CIS is used, even when the document cover 32 is in the open state, if the outline of the document can be extracted from the first image data 80, the image by the auto crop function can be used. Cutting can be performed normally. On the other hand, when the outline of the original cannot be extracted from the image data (first image data 80) obtained by (ii) reading by the image reading unit 11, the control unit 101 has an individual image by the individual image cutting unit 102. The cutout of (manuscript portion 82) is not executed. Therefore, in the image reading device 2 in which CIS is used, if the outline of the document cannot be extracted from the image data (first image data 80) when the document cover 32 is in the open state, the individual image cutout portion. Since the individual image (original portion 82) is not cut out by 102, it is possible to prevent erroneous detection / non-detection of the original by the auto crop function.
