Description
本発明は、画像読取装置とこれを用いた画像形成装置に関する。 The present invention relates to an image reading apparatus and an image forming apparatus using the same.
ファクシミリ、複写機、スキャナなどの画像形成装置に用いる画像読取装置の画像読取部に原稿を給送させる自動原稿給送装置(ADF)においては、給紙部の上側搬送路を形成する給紙上ガイドと、給紙部の外装である給紙カバー、および給紙入口部の下側搬送路となる給紙入口下ガイドを備え、前記給紙カバーと給紙上ガイドは、開放して給紙部の搬送経路を露出することが可能である構成になっているものがほとんどである。これは、ジャム処理時やメンテナンス時における操作性を確保するためである。また、給紙部入口の下搬送面のさらに下側には、両面原稿を反転させて裏面を読取るための反転搬送路を持つ構成のものが多い。 In an automatic document feeder (ADF) that feeds a document to an image reading unit of an image reading apparatus used in an image forming apparatus such as a facsimile, a copying machine, or a scanner, an upper sheet feeding guide that forms an upper conveyance path of the sheet feeding unit A sheet feed cover that is an exterior of the sheet feed unit, and a sheet feed inlet lower guide that is a lower conveyance path of the sheet feed inlet unit, and the sheet feed cover and the sheet feed upper guide are opened to open the sheet feed unit. In most cases, the conveyance path can be exposed. This is to ensure operability during jam processing and maintenance. In many cases, a reversal conveyance path for reversing a double-sided document and reading the back surface is provided further below the lower conveyance surface of the sheet feeding unit entrance.
このような構成の装置においては、原稿積載部から給紙部に原稿が搬送される場合に対して、反転経路から給紙部に原稿が搬送される場合には、原稿先端は給紙上ガイドの搬送面に比較的高角度で入射したのちに、プルアウト従動ローラ対に受け渡される。ここでの原稿先端の受け渡しが滑らかでない場合、原稿先端がプルアウト従動ローラのニップに進入する前にローラの腹に当たり、衝撃音が大きくなる場合がある。 In the apparatus having such a configuration, when the document is conveyed from the document stacking unit to the sheet feeding unit, when the document is conveyed from the reversing path to the sheet feeding unit, the leading end of the document is positioned on the sheet feeding upper guide. After entering the transport surface at a relatively high angle, it is transferred to the pull-out driven roller pair. If the delivery of the leading edge of the document is not smooth, the leading edge of the document hits the antinode of the roller before entering the nip of the pull-out driven roller, and the impact sound may increase.

以下本発明を実施するための最良の形態を、図に示す実施例を参照して説明する。 The best mode for carrying out the present invention will be described below with reference to the embodiments shown in the drawings.
本発明は、ファクシミリ、複写機、スキャナなどの画像読取装置の画像読取部に原稿を給送させる自動原稿給送装置(ADF)に関するものである。本明細書では、代表例として、複写機に搭載されるシートスルー式ADFの場合を取り上げ、その基本的な構成、動作、作用、および本発明の実施例を説明する。 The present invention relates to an automatic document feeder (ADF) that feeds a document to an image reading unit of an image reading device such as a facsimile, a copying machine, or a scanner. In the present specification, as a representative example, the case of a sheet-through ADF mounted on a copying machine is taken up, and its basic configuration, operation, action, and embodiments of the present invention will be described.
基本的な構成、動作、作用を本実施例装置の断面図(図1)、ブロック図(図2)及びフローチャート(図3〜7)を基に説明する。 A basic configuration, operation, and action will be described based on a cross-sectional view (FIG. 1), a block diagram (FIG. 2), and flowcharts (FIGS. 3 to 7) of the apparatus of the present embodiment.
読取りを行う原稿束0をセットするのは、原稿テーブル1上で、原稿面を上向きの状態で、原稿先端をストップ爪2(セット時の状態は2点鎖線で示す)に突き当ててセットすると、原稿セットフィラー31が図1に示した破線の状態から実線の状態に角度を変え、原稿セットセンサ19により原稿セットが検知される。更に原稿束0の幅方向を図示しないサイドフェンスによって搬送方向と直行する方向の位置決めを行う。 The original bundle 0 to be read is set on the original table 1 with the original surface facing upward and the front end of the original abutting against the stop claw 2 (the state at the time of setting is indicated by a two-dot chain line). The document set filler 31 changes the angle from the broken line state shown in FIG. 1 to the solid line state, and the document set sensor 19 detects the document set. Further, the document bundle 0 is positioned in a direction perpendicular to the conveyance direction by a side fence (not shown).
図示しない本体操作部よりプリントキーが押下され、本体制御部からADF制御部に原稿給紙信号が送信されると、呼出しモータ101を正転駆動して爪ホームポジションセンサ34によりストップ爪2が下方向(図中の実線の状態)に退避させる(フロー図中のステップs1:以下、単にステップ1等という。)。続いて呼出しモータ101を逆転駆動してピックアップホームポジションセンサ33によりピックアップローラ3が原稿束0を上から押さえるように下降させる(ステップs2)。また、給紙原稿テーブル面に設けられた原稿長さ検知センサ20〜22により原稿の搬送方向長さの概略が判定され(少なくとも同一原稿サイズの縦か横かを判断可能なセンサ配置が必要)、後に示す原稿幅検知結果との組合せにより原稿サイズの概略判定が行われる(ステップ3)。 When a print key is pressed from a main body operation unit (not shown) and a document feed signal is transmitted from the main body control unit to the ADF control unit, the calling motor 101 is driven to rotate forward and the stop claw 2 is lowered by the claw home position sensor 34. Retreat in the direction (solid line state in the figure) (step s1: in the flowchart, hereinafter, simply referred to as step 1 etc.). Subsequently, the calling motor 101 is driven in the reverse direction, and the pickup home position sensor 33 lowers the pickup roller 3 so as to hold the document bundle 0 from above (step s2). Further, an outline of the length of the document in the conveyance direction is determined by the document length detection sensors 20 to 22 provided on the sheet feeding document table surface (at least a sensor arrangement that can determine whether the document size is vertical or horizontal is necessary). Then, a rough determination of the document size is performed by a combination with the document width detection result described later (step 3).
ピックアップローラ3は、給紙モータ102の正転により最上位の原稿を給紙口に搬送する方向に回転駆動し、原稿テーブル1上の数枚(理想的には1枚)の原稿を給紙ベルト5とリバースコロ4によって構成された原稿分離部へと給送する。給紙ベルト5は給紙モータ102の正転により給紙方向に駆動され、リバースコロ4は給紙と逆方向に回転駆動され最上位の原稿とその下の原稿を分離して、最上位の原稿のみを給紙できる構成となっている。給紙ベルト5とリバースコロ4との作用により1枚に分離された原稿は給紙ベルト5によって更に送られ、突き当てセンサ24によって先端が検知された時点から所定量原稿搬送して給紙モータ102の正転駆動を停止させる(ステップ4)。この時、前出の所定量を突き当てセンサ24からプルアウトローラ6までの距離よりも大きくすることで、プルアウトローラ6に一定の撓みを形成した状態で原稿が停止することになる。この時点で呼出しモータ101を逆転させることで、ピックアップローラ3を原稿上面から退避させ、原稿を給紙ベルト5の搬送力のみで送ることにより(ステップ5)、原稿先端がプルアウトローラ6及び従動ローラ7のニップに進入し、分離給送時に発生した原稿の曲がり(スキュー)を補正できる。 The pickup roller 3 is driven to rotate in the direction in which the uppermost document is conveyed to the sheet feeding port by the normal rotation of the sheet feeding motor 102, and feeds several (ideally one) documents on the document table 1. The paper is fed to an original separation unit constituted by a belt 5 and a reverse roller 4. The paper feed belt 5 is driven in the paper feed direction by the forward rotation of the paper feed motor 102, and the reverse roller 4 is driven to rotate in the reverse direction to the paper feed, separating the uppermost document and the original document below it, Only a document can be fed. The document separated into one sheet by the action of the sheet feeding belt 5 and the reverse roller 4 is further fed by the sheet feeding belt 5, and the document is fed by a predetermined amount from the time when the leading edge is detected by the abutting sensor 24 to feed the document. The forward rotation drive 102 is stopped (step 4). At this time, by making the above-mentioned predetermined amount larger than the distance from the abutting sensor 24 to the pull-out roller 6, the document is stopped in a state in which the pull-out roller 6 is formed with a certain amount of bending. At this time, the pick-up motor 101 is reversely rotated to retract the pickup roller 3 from the upper surface of the document, and the document is fed only by the conveying force of the paper feed belt 5 (step 5). 7 can enter the nip 7 and correct the bending (skew) of the document that occurs during separation feeding.
プルアウトローラ6は、前記スキュー補正機能を有すると共に、分離後にスキュー補正された原稿を読取入口ローラ8まで搬送するためのローラで、給紙モータ102の逆転により駆動される。またこの時(給紙モータ逆転時)、プルアウトローラ7は駆動されるが、図示しないワンウェイクラッチの作用によりピックアップローラ3と給紙ベルト5は駆動されていない。原稿幅センサ25は奥行き方向に複数個並べられ、プルアウトローラ6により搬送された原稿の搬送方向に直行する幅方向の情報を取得する。 The pull-out roller 6 has a skew correction function and is a roller for transporting the skew-corrected document to the reading entrance roller 8 after separation, and is driven by the reverse rotation of the paper feed motor 102. At this time (when the paper feed motor reverses), the pull-out roller 7 is driven, but the pickup roller 3 and the paper feed belt 5 are not driven by the action of a one-way clutch (not shown). A plurality of document width sensors 25 are arranged in the depth direction, and acquire information in the width direction orthogonal to the transport direction of the document transported by the pull-out roller 6.
そして、前述した原稿テーブル1上の原稿長さ検知センサ20〜22の検知結果から取得した長さ情報と、該幅情報との組合せにより本体制御部111に原稿テーブル1上に積載された原稿束0のサイズ情報を送信する。尚、原稿の搬送方向の正確な長さは原稿の先端後端を突き当てセンサ24で検知する間に搬送した距離をモータ駆動パルス数をカウントすることで算出する。プルアウトローラ6の駆動により読取入口ローラ8に原稿が搬送される際には、原稿搬送速度を高速に設定して原稿を読取り部へ送り込む処理時間の短縮が図られており、特に2枚目以降の原稿ではこの高速搬送により前原稿との紙間を短縮することで生産性を向上させることができる(ステップ6)。 Then, a bundle of documents stacked on the document table 1 in the main body control unit 111 by a combination of the length information acquired from the detection results of the document length detection sensors 20 to 22 on the document table 1 and the width information. Send zero size information. The exact length of the document in the conveyance direction is calculated by counting the number of motor driving pulses for the distance conveyed while the leading edge and the trailing edge of the document are detected by the abutment sensor 24. When the document is conveyed to the reading entrance roller 8 by driving the pull-out roller 6, the document conveying speed is set to a high speed and the processing time for feeding the document to the reading unit is shortened. In this document, productivity can be improved by shortening the paper gap with the previous document by this high-speed conveyance (step 6).
原稿先端が読取入口センサ26により検出されると、読取入口ローラ8に原稿先端が進入する前に減速を開始する。ここで、読取り入口センサ26から読取り入口ローラ8までの距離よりもYmmだけ搬送距離が長くなるように給紙モータ102を停止させると、停止している読取り入口ローラ8のニップ部に原稿先端が突き当り、一定の撓みを形成した状態で原稿が停止することになり、プルアウトローラ6による原稿搬送時に発生したスキューを補正する事ができる。原稿が読取り入口ローラ8のニップ部で一時停止(レジスト停止)すると、インターフェース手段107を介して本体制御部111にレジスト停止信号を送信する(ステップ7)。 When the leading edge of the document is detected by the reading entrance sensor 26, deceleration starts before the leading edge of the document enters the reading entrance roller 8. Here, when the paper feed motor 102 is stopped so that the conveyance distance is longer by Y mm than the distance from the reading entrance sensor 26 to the reading entrance roller 8, the leading edge of the document is placed at the nip portion of the stopped reading entrance roller 8. At the end, the document stops with a certain amount of deflection, and the skew generated when the document is conveyed by the pull-out roller 6 can be corrected. When the original is temporarily stopped (resist stop) at the nip portion of the reading entrance roller 8, a registration stop signal is transmitted to the main body control unit 111 via the interface means 107 (step 7).
続いて本体制御部111より読取り開始信号を受信すると、原稿読取り動作が開始する。読取りモータ103を正転駆動して読取入口ローラ8、読取出口ローラ10を読取り倍率に応じた搬送速度で駆動する(ステップ8)。原稿の先端をレジストセンサ27にて検知すると、読取りモータ103のパルスカウントを開始し、原稿先端が読取り部に到達するタイミングで本体制御部111に対して副走査方向有効画像領域を示すゲート信号を送出する(ステップ9)。このゲート信号は、通常は原稿後端が読取部を抜けるまで送出される(ステップ11)。読取部を通過した原稿は読取出口ローラ10及び排紙ローラ12により搬送され(A方向)、排紙トレイ14に排出される(ステップ12)。 Subsequently, when a reading start signal is received from the main body control unit 111, the document reading operation starts. The reading motor 103 is driven to rotate forward to drive the reading inlet roller 8 and the reading outlet roller 10 at a conveying speed corresponding to the reading magnification (step 8). When the leading edge of the original is detected by the registration sensor 27, the pulse count of the reading motor 103 is started, and a gate signal indicating an effective image area in the sub-scanning direction is sent to the main body controller 111 at the timing when the leading edge of the original reaches the reading portion. Send out (step 9). This gate signal is normally sent until the trailing edge of the document leaves the reading section (step 11). The document that has passed through the reading unit is conveyed by the reading exit roller 10 and the paper discharge roller 12 (direction A) and discharged to the paper discharge tray 14 (step 12).
両面原稿の場合は、表面読取時に読取部を抜けた原稿先端が排紙ローラ12に到達する前に反転ソレノイド105のONにより切替爪15が2点鎖線の位置に切り替わり、読取りモータ103にて駆動される排紙ローラ12及び下従動コロ13と、反転モータ104により駆動される反転ローラ16及び従動コロ17によりB方向に搬送される(ステップ13)。B方向に搬送された原稿の後端が排紙ローラ12を抜けると(読取り出口センサ29が原稿後端を検出してから所定パルス後)、反転ソレノイド105をOFFとして切替爪15は図中の実線の位置へ戻り、さらに所定パルス後反転モータ104の逆転駆動により反転ローラ16が逆転し、原稿はC方向にスイッチバックする。 In the case of a double-sided document, the switching claw 15 is switched to the position indicated by a two-dot chain line by turning on the reverse solenoid 105 before the leading edge of the document that has passed through the reading unit at the time of surface reading reaches the paper discharge roller 12 and is driven by the reading motor 103 The paper is conveyed in the B direction by the discharged paper roller 12 and the lower driven roller 13 and the reverse roller 16 and the driven roller 17 driven by the reverse motor 104 (step 13). When the trailing edge of the document conveyed in the B direction passes through the paper discharge roller 12 (after a predetermined pulse after the reading exit sensor 29 detects the trailing edge of the document), the reverse solenoid 105 is turned off and the switching claw 15 is turned on in the drawing. Returning to the position of the solid line, the reverse roller 16 is reversely rotated by the reverse rotation drive of the reverse motor 104 after a predetermined pulse, and the document is switched back in the C direction.
この時、読取りモータ103の駆動方向は同一方向、反転モータ104の駆動方向は逆方向となり、処理時間短縮のために反転モータ104及び読取りモータ103を高速駆動する。原稿がスイッチバックを始めると所定パルス後に給紙モータ102を逆転(プルアウトローラ6を駆動する方向に回転)高速駆動する(ステップ14)。 At this time, the driving direction of the reading motor 103 is the same direction and the driving direction of the reversing motor 104 is the reverse direction, and the reversing motor 104 and the reading motor 103 are driven at a high speed in order to shorten the processing time. When the document starts to switch back, the paper feed motor 102 is reversely rotated (rotated in the direction in which the pull-out roller 6 is driven) at a high speed after a predetermined pulse (step 14).
スイッチバックした原稿は、排紙ローラ12及び上従動コロ18により図中矢印C方向に搬送され、片面時と同様に、プルアウトローラ6、読取入口ローラ8を経て裏面読取りのために読取り入口ローラニップ部で一時停止する。裏面読取り時においても読取り入口ローラニップ部に原稿先端を突当ててスキュー補正を行うためには、原稿先端が読取入口ローラ8に達する前に読取りモータ103の駆動を停止している必要があるため、読取りモータ103は原稿先端が読取り入口センサ26によって検知された時点で駆動を停止する(ステップ16)。裏面読取りのためにレジスト停止した原稿は表面読取り時と同様に読取り開始信号を受信後指定された倍率に応じた搬送速度で原稿を読取り位置28へと搬送する。裏面の読取が完了すると再度ページ合わせのための同様の反転動作が行われ排紙ローラ13により排紙トレイ14に排出される。ページ合わせのための反転動作時は読取り倍率に応じた速度で搬送する必要は無いので、高速搬送のまま読取り位置を通過させ、原稿後端を読取り出口センサ29にて検知したら減速することにより原稿排出時の飛出し防止と処理時間短縮を図っている(ステップ15)。 The document that has been switched back is conveyed by the paper discharge roller 12 and the upper driven roller 18 in the direction of the arrow C in the drawing, and in the same way as on one side, it passes through the pull-out roller 6 and the reading inlet roller 8 to read the back surface. Pause at. In order to perform skew correction by abutting the leading end of the document against the reading entrance roller nip even when reading the back side, it is necessary to stop the driving of the reading motor 103 before the leading end of the document reaches the reading entrance roller 8. The reading motor 103 stops driving when the leading edge of the document is detected by the reading inlet sensor 26 (step 16). The document whose registration is stopped for reading the back side is conveyed to the reading position 28 at a conveyance speed corresponding to the designated magnification after receiving the reading start signal in the same manner as the front side reading. When the reading of the back surface is completed, the same reversing operation for page alignment is performed again, and the paper is discharged onto the paper discharge tray 14 by the paper discharge roller 13. During the reversing operation for page alignment, it is not necessary to convey at a speed corresponding to the reading magnification. Therefore, the document is allowed to pass through the reading position while being conveyed at high speed, and when the trailing edge of the document is detected by the reading exit sensor 29, the document is decelerated. It prevents jumping out during discharge and shortens the processing time (step 15).
以下では、前述の装置における本発明の実施例を説明する。図8は、比較のために示す、受け渡し形状を持たない従来の構成である。反転経路から給紙部に搬送されてくる原稿の先端が給紙上ガイド52に入射する際、原稿積載部から給紙部に搬送されてくる場合とは異なり比較的高角度に給紙上ガイド52に入射し、プルアウト従動ローラ7に受け渡される。 In the following, embodiments of the present invention in the above-described apparatus will be described. FIG. 8 shows a conventional configuration having no delivery shape shown for comparison. Unlike the case where the leading edge of the document conveyed from the reversing path to the sheet feeding unit enters the sheet feeding upper guide 52, unlike the case where the document is conveyed from the document stacking unit to the sheet feeding unit 52, Incident light is transferred to the pull-out driven roller 7.
図9は、受け渡し形状部53が給紙上ガイド52に一体成型で形成された例である。一体成型で形成された場合、部品点数は増加せず、構成は単純で済む。 FIG. 9 shows an example in which the delivery shape portion 53 is formed integrally with the paper feed upper guide 52. When formed by integral molding, the number of parts does not increase and the configuration is simple.
また図10の例は、受け渡し形状が給紙上ガイド52とは別部材で、かつ可撓性部材54で形成された一例である。受け渡し形状が給紙上ガイド52とは別部材の場合、新しく受け渡し形状を設けたり変更したりする場合、大物樹脂部品である給紙上ガイド52の改造はしなくて済む。 Further, the example of FIG. 10 is an example in which the delivery shape is a member different from the paper feed upper guide 52 and is formed of the flexible member 54. When the delivery shape is a different member from the paper feed guide 52, when a new delivery shape is provided or changed, it is not necessary to modify the paper feed guide 52, which is a large resin part.
図11は、受け渡し形状が給紙上ガイド52に一体成型で形成され、かつ受け渡し形状の幅がプルアウト従動ローラ7のコロ部の幅よりも大きい一例である。受け渡し形状の幅がプルアウト従動ローラ7のコロ部の幅よりも大きければ、受け渡しの作用は確実に得られる。 FIG. 11 shows an example in which the delivery shape is formed integrally with the paper feed upper guide 52 and the width of the delivery shape is larger than the width of the roller portion of the pull-out driven roller 7. If the width of the delivery shape is larger than the width of the roller portion of the pull-out driven roller 7, the delivery action can be reliably obtained.
図12は、受け渡し形状が給紙上ガイド52とは別部材の可撓性部材54で形成され、かつ受け渡し形状の幅がプルアウト従動ローラ7のコロ部の幅以下である一例である。受け渡しの作用としては、必ずしもコロ幅全体を受け渡す必要はなく、コロ幅の部分的な範囲を受け渡せばよく、コロ幅の中央付近とするのがバランスがよい。 FIG. 12 shows an example in which the delivery shape is formed of a flexible member 54 that is a separate member from the paper feed upper guide 52, and the width of the delivery shape is equal to or less than the width of the roller portion of the pull-out driven roller 7. As an effect of the transfer, it is not always necessary to transfer the entire roller width, it is sufficient to transfer a partial range of the roller width, and it is well balanced to be near the center of the roller width.
図13は、受け渡し形状が給紙上ガイド52とは別部材の可撓性部材54で形成され、可撓性部材54の給紙上ガイド52への取り付け手段は、搬送面の両面粘着テープ55と、搬送面とは別の面の両面粘着テープ55、さらに搬送面とは反対側の、給紙カバー51内部の固定ネジ56で取り付けられている。 In FIG. 13, the delivery shape is formed by a flexible member 54 that is a separate member from the paper feed upper guide 52, and the means for attaching the flexible member 54 to the paper feed upper guide 52 includes a double-sided adhesive tape 55 on the transport surface, It is attached with a double-sided adhesive tape 55 on a surface different from the transport surface, and a fixing screw 56 inside the paper feed cover 51 on the side opposite to the transport surface.
可撓性部材の紙搬送ガイド類への取り付け方法としては、平坦な可撓性部材を、平坦な紙搬送ガイドの搬送面に、両面粘着テープで取り付けるのが一般的である。しかしながらこの場合、経時で両面粘着テープの粘着力が弱まったり、また機械の構成によっては、図14に示すように、給紙カバー51と給紙上ガイド52は、ジャム処理時やメンテナンス時に開放することが可能であり、ユーザーが容易にアクセスできる部分であるので、ユーザーが触れたりして、可撓性部材の意図しない脱落が発生し、紙搬送経路をふさいでしまいジャムが発生する場合がある。 As a method for attaching the flexible member to the paper conveyance guides, it is common to attach a flat flexible member to the conveyance surface of the flat paper conveyance guide with a double-sided adhesive tape. However, in this case, the adhesive force of the double-sided adhesive tape weakens over time, and depending on the configuration of the machine, as shown in FIG. 14, the paper feed cover 51 and the paper feed upper guide 52 may be opened during jam processing or maintenance. Since this is a part that can be easily accessed by the user, there is a case where the user touches the flexible member to cause an unintentional dropout, which blocks the paper conveyance path and causes a jam.
これに関して、両面粘着テープによる取付個所を複数箇所設けたり、取付手段を、外すためにドライバーが必要なネジにしたり、さらに、両面粘着テープあるいはネジによる取付個所を、ユーザーが容易にアクセスできない個所にすることにより、可撓性部材の意図しない脱落が発生することを防止できる。 In this regard, multiple attachment points with double-sided adhesive tape are provided, screws that require a screwdriver to remove the attachment means, and attachment points with double-sided adhesive tape or screws can be easily accessed by the user. By doing so, it is possible to prevent unintentional dropping of the flexible member.
以上述べたように、本発明では、給紙上ガイドからプルアウト従動ローラに原稿を滑らかに受け渡す、受け渡し形状部を持つので、反転経路からの給紙部へ原稿が搬送されてくる際の衝撃音を緩和でき、受け渡し形状部を樹脂製の給紙上ガイドと一体成型で形成して部品点数を増やすことなく構成を単純化できる。 As described above, according to the present invention, since there is a transfer shape portion that smoothly transfers the document from the paper feed upper guide to the pull-out driven roller, the impact sound generated when the document is conveyed from the reverse path to the paper feed portion. The transfer shape portion can be formed by integral molding with the resin feed guide and the configuration can be simplified without increasing the number of parts.
また受け渡し形状部は、樹脂製給紙上ガイドと別部材で形成すれば、受け渡し形状部を変更する場合に大物樹脂部品である給紙上ガイドを改造する必要がない。受け渡し形状部を、樹脂製給紙上ガイドと別部材の可撓性部材で形成すれば、給紙カバー開放時に加圧が解除されるプルアウト従動ローラに、受け渡し部材を十分近くまで近づけることができる。受け渡し形状部を樹脂製給紙上ガイドと別部材の可撓性部材で形成すると、給紙カバー開放時に加圧が解除されるプルアウト従動ローラに、受け渡し部材を十分近くまで近づけることができる。 Further, if the delivery shape portion is formed of a separate member from the resin-made paper feed upper guide, it is not necessary to modify the paper feed upper guide, which is a large resin part, when changing the delivery shape portion. If the delivery shape portion is formed of a flexible member that is a separate member from the resin feed upper guide, the delivery member can be brought close enough to the pull-out driven roller whose pressure is released when the feed cover is opened. If the delivery shape portion is formed of a flexible member that is a separate member from the resin-made upper paper feed guide, the delivery member can be brought close enough to the pull-out driven roller whose pressure is released when the paper feed cover is opened.
さらに受け渡し形状部の幅を、プルアウト従動ローラのコロ部の幅よりも大きくすると、理論上の受け渡しの効果を確実に得ることができる。逆に、プルアウト従動ローラのコロ部の幅以下とすると、受け渡しの効果とコストのバランスが最適な状態を得ることができる。 Furthermore, if the width of the delivery shape portion is made larger than the width of the roller portion of the pull-out driven roller, the theoretical delivery effect can be reliably obtained. On the other hand, when the width is equal to or less than the width of the roller portion of the pull-out driven roller, an optimal state can be obtained in which the balance between the delivery effect and the cost is optimal.
また、受け渡し形状部を形成する可撓性部材の色を透明とすれば、可撓性部材の裏にゴミがたまった場合にすぐに気付いて清掃することができる。不透明であれば、逆に、可撓性部材の裏にゴミがたまった場合に美観を損ねることがない。 In addition, if the color of the flexible member forming the delivery shape portion is transparent, it can be immediately noticed and cleaned when dust accumulates on the back of the flexible member. On the contrary, if it is opaque, the aesthetic appearance will not be impaired if dust accumulates on the back of the flexible member.
なお、受け渡し形状を形成する可撓性部材の、給紙上ガイドへの取り付け手段は、ユーザーが容易にアクセスできない少なくとも1ヶ所以上の面で、両面粘着テープにて取り付けるようにすれば、ユーザーが誤って可撓性部材を容易に取り除いてしまうことはない。また受け渡し形状部を形成する可撓性部材の、給紙上ガイドへの取り付けを少なくとも1ヶ所以上の固定ネジで行えば、ユーザーが誤って可撓性部材を容易に取り除いてしまうことはない。 Note that if the flexible member that forms the delivery shape is attached to the paper feed guide with at least one surface that cannot be easily accessed by the user using double-sided adhesive tape, the user will be mistaken. Thus, the flexible member is not easily removed. Further, if the flexible member forming the delivery shape portion is attached to the paper feed guide with at least one fixing screw, the user will not easily remove the flexible member by mistake.

In addition, the flexible member that forms the delivery shape part can be attached to the paper feed guide with at least one surface that cannot be easily accessed by the user with fixing screws. The flexible member is not easily removed.
