Description

本発明は、給紙部と排紙部と画像記録部とを備える画像記録装置に関し、特に、排紙部が給紙部の上方に配置されている画像記録装置及びそれに適用する給紙トレイに関するものである。   The present invention relates to an image recording apparatus including a paper feed unit, a paper discharge unit, and an image recording unit, and more particularly to an image recording device in which a paper discharge unit is disposed above a paper feed unit and a paper feed tray applied thereto. Is.
従来から、プリンタやファクシミリ等の画像記録装置においては、被記録媒体(用紙、カットシート等)を給送する給紙部と、この給紙部から給送された被記録媒体に画像を記録する画像記録部と、画像の記録された被記録媒体をユーザが取得できるように画像記録部を経た被記録媒体を排出する排紙部とを備えた構造が知られている。   2. Description of the Related Art Conventionally, in an image recording apparatus such as a printer or a facsimile, an image is recorded on a paper feeding unit that feeds a recording medium (paper, cut sheet, etc.) and a recording medium fed from the paper feeding unit. There is known a structure including an image recording unit and a paper discharge unit that discharges the recording medium that has passed through the image recording unit so that a user can acquire the recording medium on which an image is recorded.
例えば、特許文献1等には、給紙部に備えられる給紙トレイに、長さサイズの異なる被記録媒体を収容できるように、給紙方向上流側の端部に回動可能な補助トレイを付加し、給紙トレイの載置面積を拡張可能にする技術が記載されている。この特許文献1では、給紙トレイの給紙方向上流側の端部近傍に、凹状の収納部を形成し、拡張しないときには補助トレイはその収納部に収納されて、全体をコンパクトにすることができる。   For example, in Patent Document 1 or the like, an auxiliary tray that can be rotated at the end on the upstream side in the paper feeding direction is provided in the paper feeding tray provided in the paper feeding unit so that recording media having different length sizes can be accommodated. In addition, a technique is described in which the mounting area of the paper feed tray can be expanded. In Patent Document 1, a concave storage portion is formed in the vicinity of the upstream end of the paper feed direction in the paper feed tray, and when not expanded, the auxiliary tray is housed in the storage portion to make the whole compact. it can.
一方、特許文献2には、排紙部の排紙トレイに回動可能な補助トレイを付加し、排紙トレイの載置面積を拡張可能にする技術が記載されている。これにより、排紙方向にサイズの長い被記録媒体を排出する際には、排紙トレイの補助トレイを拡張し、排出された被記録媒体を排紙トレイと補助とトレイとで安定的に支持することができる。また、この特許文献2では、排紙部を給紙部の上方に配置し、且つ給紙部から排紙部へ略Uターン形状の搬送路を備える構造も記載されている。

On the other hand, Patent Document 2 describes a technique in which a rotatable auxiliary tray is added to a paper discharge tray of a paper discharge unit so that the placement area of the paper discharge tray can be expanded. As a result, when ejecting a long recording medium in the paper ejection direction, the auxiliary tray of the paper ejection tray is expanded and the ejected recording medium is stably supported by the paper ejection tray, the auxiliary, and the tray. can do. Further, this Patent Document 2 also describes a structure in which a paper discharge unit is disposed above the paper feed unit and a substantially U-turn shaped conveyance path is provided from the paper feed unit to the paper discharge unit.
JP-A-6-9066 (see FIG. 1) JP-A-10-167547 (see FIG. 1)
ところで、近年、画像記録装置では、特許文献2に記載されているような給紙部と排紙部とを上下に配置する構造において、給紙部と排紙部との上下の距離を近接させることで、装置全体の小型化、薄型化が図られている。そのため、給紙トレイ及び排紙トレイの構造において、できるだけ部品の簡略化や兼用化を図り、前述した装置全体の小型化や薄型化、さらにはコストダウンを進めたいという要望があった。   Incidentally, in recent years, in an image recording apparatus, in a structure in which a paper feed unit and a paper discharge unit are arranged up and down as described in Patent Document 2, the vertical distance between the paper feed unit and the paper discharge unit is made closer. As a result, the entire apparatus is reduced in size and thickness. Therefore, there has been a demand for simplifying and sharing parts as much as possible in the structure of the paper feed tray and the paper discharge tray, thereby reducing the overall size and thickness of the apparatus as described above, and further reducing the cost.
しかしながら、特許文献1では、補助トレイを収納できるように、給紙トレイに収容部が凹設されている。従って、補助トレイが開かれて収納部の凹状面が露出しているときには、給紙トレイに収容されている被記録媒体がその凹状面に落ち込むように撓む現象が生じる。被記録媒体が、撓んだままあるいは撓み癖がついたままであると、給紙手段で重送されたり、搬送途中で皺や紙ジャム(紙詰まり)を生じたりする給紙不良が発生し易いうえに、画像記録部にてインクジェット式の記録ヘッドが使用されている場合には、記録ヘッドと被記録媒体の記録面との距離が部分的に異なることになり、記録品質も悪化するという課題も有している。   However, in Patent Document 1, a storage portion is recessed in the paper feed tray so that the auxiliary tray can be stored. Therefore, when the auxiliary tray is opened and the concave surface of the storage portion is exposed, a phenomenon occurs in which the recording medium stored in the paper feed tray is bent so as to fall into the concave surface. If the recording medium remains bent or has a bent wrinkle, it is likely to cause a paper feed failure such as double feeding by the paper feeding means, or wrinkles or paper jams (paper jams) during transportation. In addition, when an ink jet recording head is used in the image recording unit, the distance between the recording head and the recording surface of the recording medium is partially different, and the recording quality is also deteriorated. Also have.
本発明は、上記課題を解消するものであり、給紙トレイ及び排紙トレイの構造の簡略化を図りながら、装置全体の薄型化を可能とし、さらに、被記録媒体の搬送不良等を改善できる画像記録装置及び給紙トレイの提供を目的とするものである。   The present invention solves the above-described problems, enables the overall thickness of the apparatus to be reduced while simplifying the structure of the paper feed tray and the paper discharge tray, and further improves the conveyance failure of the recording medium. The object is to provide an image recording apparatus and a paper feed tray.

請求項1に記載の発明によれば、排紙トレイを補助するための排紙補助トレイを、排紙トレイの下方に位置する給紙トレイに取り付け、排紙補助トレイの移動に必要な上下方向のスペースとして、排紙トレイと給紙トレイとの間の隙間を有効活用しているから、排紙トレイを補助して被記録媒体を安定的に支持する排紙補助トレイを、装置全体の薄型化を損なうことなく設けることができる。   According to the first aspect of the present invention, the paper discharge auxiliary tray for assisting the paper discharge tray is attached to the paper feed tray positioned below the paper discharge tray, and the vertical direction required for the movement of the paper discharge auxiliary tray Since the gap between the paper discharge tray and the paper feed tray is effectively utilized as the space for the paper discharge, the paper discharge auxiliary tray that supports the recording medium stably by supporting the paper discharge tray is thin in the overall device. It can be provided without impairing the process.
また、排紙補助トレイは、拡張位置と収納位置との間で移動可能に設けられているため、給紙トレイへの被記録媒体の補給等の妨げとならないように、不要なときには排紙補助トレイを収納することができる。   In addition, since the discharge auxiliary tray is movably provided between the extended position and the storage position, the discharge auxiliary tray is provided when it is unnecessary so as not to hinder the supply of the recording medium to the paper supply tray. Tray can be stored.
また、排紙補助トレイを収納するために給紙トレイに凹設された第1収納部には、被記録媒体の下方への撓みを規制する規制部が設けられているため、給紙トレイに収容されている被記録媒体に撓み癖等が付くことを防止でき、搬送不良や記録品質の悪化を招く心配もない。   In addition, the first storage portion that is recessed in the paper feed tray for storing the paper discharge auxiliary tray is provided with a restriction portion that restricts the downward deflection of the recording medium. It is possible to prevent the recording medium accommodated from being bent or the like, and there is no fear of causing poor conveyance or deterioration of recording quality.
請求項2に記載の発明によれば、第1収納部に規制部としての第1突条部を被記録媒体の支持に必要な高さ寸法に形成し、排紙補助トレイに長穴を形成したから、排紙補助トレイを収納した状態で第1突条部の高さ内に排紙補助トレイが配置され、高さをコンパクトにできる。   According to the second aspect of the present invention, the first protrusion as the restricting portion is formed in the first storage portion to a height required for supporting the recording medium, and the elongated hole is formed in the discharge auxiliary tray. Therefore, the discharge auxiliary tray is disposed within the height of the first protrusion while the discharge auxiliary tray is stored, and the height can be made compact.
また、規制部が突条に形成され、これを遊嵌するために排紙補助トレイに穿設される部位が長穴という細長い形状でよいから、その穿孔面積が小さくすみ、排紙補助トレイの剛性の低下を防ぐことができる。   In addition, since the restricting portion is formed on the ridge, and the portion formed in the discharge auxiliary tray for loosely fitting it may be an elongated shape such as a long hole, the perforation area is reduced, and the discharge auxiliary tray A decrease in rigidity can be prevented.
請求項3に記載の発明によれば、排紙補助トレイが排紙方向の下流側が上流側よりも高い傾斜状態で保持される、換言すると、排紙補助トレイは、拡張位置では、下方に位置する給紙トレイ側を基端部として、排紙方向の下流側が上方となるように斜めに突出するから、排紙トレイから排紙方向下流側にはみ出した被記録媒体は、排紙トレイと排紙補助トレイとに跨って堆積される。そして、このとき被記録媒体の排紙方向下流側端部は、排紙補助トレイの傾斜に沿って、排紙方向の下流側の方が上方に持ち上げられ状態となるため、安定的に堆積される。その結果、被記録媒体が排紙トレイでの堆積時に、垂れ下がって脱落することを防止できる。   According to the third aspect of the present invention, the discharge auxiliary tray is held in an inclined state in which the downstream side in the discharge direction is higher than the upstream side, in other words, the discharge auxiliary tray is positioned below in the extended position. The recording medium that protrudes obliquely so that the downstream side in the paper discharge direction is upward, with the paper feed tray side to be used as the base end, prevents the recording medium that protrudes from the paper discharge tray to the downstream side in the paper discharge direction. It is deposited across the paper auxiliary tray. At this time, the downstream end portion of the recording medium in the sheet discharge direction is stably deposited because the downstream side in the sheet discharge direction is lifted upward along the inclination of the sheet discharge auxiliary tray. The As a result, it is possible to prevent the recording medium from sagging and dropping when it is deposited on the paper discharge tray.
請求項4に記載の発明によれば、補助支持部材をスライドさせて伸ばすことで、給紙トレイは、長さサイズの長い被記録媒体にも対応してこれを載置することができる。また、排紙補助トレイは、補助支持部材をスライドして伸ばした状態で拡張することにより、排紙補助トレイと排紙トレイとに跨って支持できる被記録媒体の長さサイズをさらに長くすることができる。そのため、前記補助支持部材や排紙補助トレイを伸ばしていない状態では、見掛け上、装置全体が小型に構成されているが、実際に対応できる被記録媒体の長さサイズは大きく設定することができ、装置の汎用性が高められる。   According to the fourth aspect of the invention, the auxiliary support member is slid and extended, so that the paper feed tray can be placed on a recording medium having a long length. Further, the discharge auxiliary tray is extended in a state where the auxiliary support member is slid and extended, thereby further increasing the length size of the recording medium that can be supported across the discharge auxiliary tray and the discharge tray. Can do. Therefore, when the auxiliary support member and the paper discharge auxiliary tray are not extended, the entire apparatus is apparently small, but the length of the recording medium that can be actually handled can be set large. The versatility of the device is enhanced.
請求項5に記載の発明によれば、把持用開口部が設けられることで、補助支持部材をスライドして伸ばす際の作業をユーザが簡単に行うことができる。そして、この把持用開口部の内側部を排紙補助トレイの傾斜状態の保持に利用するから、前記傾斜状態を保持するための特別な構造の付加は不要となる。   According to the fifth aspect of the present invention, the gripping opening is provided, so that the user can easily perform the work when sliding and extending the auxiliary support member. Since the inside portion of the grip opening is used for maintaining the inclined state of the auxiliary discharge tray, it is not necessary to add a special structure for maintaining the inclined state.
請求項6に記載の発明によれば、補助支持部材に長手の第1突条部が一体的に形成されることで、第1突条部が補強用のリブとして機能するから、補助支持部材の剛性を高くすることができる。   According to the sixth aspect of the present invention, since the first long ridge portion is integrally formed with the auxiliary support member, the first ridge portion functions as a reinforcing rib. The rigidity of can be increased.
また、第1突条部を遊嵌するために排紙補助トレイに設けられる長穴を、排紙補助トレイの回動の支点(枢軸)よりも離れた位置に穿設できるから、排紙補助トレイの剛性の低下をさらに防止することができる。   In addition, a slot provided in the paper discharge auxiliary tray for loosely fitting the first protrusion can be drilled at a position away from the pivot point of the paper discharge auxiliary tray. A decrease in the rigidity of the tray can be further prevented.
請求項7に記載の発明によれば、被記録媒体は、略面一に形成された、給紙トレイの底板と第1突条部の上面とに当接して支持されるから、これらに支持されているときの平坦性が向上される。   According to the seventh aspect of the invention, the recording medium is supported by being in contact with the bottom plate of the paper feed tray and the upper surface of the first protrusion, which are formed substantially flush with each other. The flatness when being applied is improved.
請求項8に記載の発明によれば、補助支持部材の上面が給紙トレイの底板よりも低く設けられていても、第2突条部の上面の高さが給紙トレイの底板の上面の高さと略面一に形成され、被記録媒体はこれらに支持されるから、被記録媒体が補助支持部材側に沈み込んで撓むことを防止できる。   According to the eighth aspect of the present invention, even if the upper surface of the auxiliary support member is provided lower than the bottom plate of the paper feed tray, the height of the upper surface of the second protrusion is equal to the upper surface of the bottom plate of the paper feed tray. Since the recording medium is formed substantially flush with the height and supported by these, it is possible to prevent the recording medium from sinking into the auxiliary support member and bending.
請求項9に記載の発明によれば、第2突条部を長くすることで、被記録媒体の支持に対する安定性が高められる。前述したように長穴の穿設に起因する排紙補助トレイの剛性低下を防ぐために、第1突条部の長さの設定には限界があるため、第2突条部を長くすることで、より確実に被記録媒体の撓みを防止できるのである。   According to the ninth aspect of the present invention, the stability with respect to the support of the recording medium is enhanced by elongating the second protrusion. As described above, in order to prevent the rigidity of the paper discharge auxiliary tray from being lowered due to the drilling of the long hole, there is a limit in setting the length of the first ridge portion. Therefore, by increasing the length of the second ridge portion, Thus, it is possible to more reliably prevent the recording medium from being bent.
請求項10に記載の発明によれば、排紙トレイには、排紙方向の下流側端部、すなわち外方側の端部に切欠部が設けられているから、排紙トレイに覆われた給紙トレイに、外方側から手を入れて用紙を補給する動作が行い易くなる。   According to the invention described in claim 10, since the discharge tray is provided with the notch at the downstream end in the discharge direction, that is, the outer end, the discharge tray is covered with the discharge tray. The operation of replenishing paper by putting a hand into the paper feed tray from the outside becomes easy.
また、排出された被記録媒体が、例えば、はがきサイズ等の小さいサイズの場合、切欠部から給紙トレイ側に落ち込むことがあるが、第1突条部及び第2突条部の給紙方向の下流側(すなわち排紙方向の上流側)の端部は、その高さが給紙方向の下流側に向かって徐々に低くなるテーパ形状に形成されている、換言すれば、面取りされているから、切欠部から落ち込んだ被記録媒体が、第1突条部及び第2突条部の角にぶつかって引っ掛かることを防止できる。   Further, when the discharged recording medium is a small size such as a postcard size, for example, the recording medium may fall from the notch portion toward the paper feed tray, but the feeding direction of the first and second ridges The end of the downstream side (that is, the upstream side in the paper discharge direction) is formed in a tapered shape whose height gradually decreases toward the downstream side in the paper feeding direction, in other words, chamfered. Therefore, it is possible to prevent the recording medium that has fallen from the notch from colliding with and catching on the corners of the first protrusion and the second protrusion.
請求項11に記載の発明によれば、排紙トレイを補助するための排紙補助トレイを、排紙トレイの下方に位置する給紙トレイの底板に設け、排紙補助トレイの移動に必要な上下方向のスペースとして、排紙トレイと前記底板との間の隙間を有効活用しているから、排紙トレイを補助して被記録媒体を安定的に支持する排紙補助トレイを、装置全体の薄型化を損なうことなく設けることができる。   According to the eleventh aspect of the present invention, the discharge auxiliary tray for assisting the discharge tray is provided on the bottom plate of the paper feed tray located below the discharge tray, and is necessary for the movement of the discharge auxiliary tray. Since the gap between the paper discharge tray and the bottom plate is effectively utilized as the vertical space, a paper discharge auxiliary tray that supports the recording medium stably by supporting the paper discharge tray is provided for the entire apparatus. It can be provided without impairing thinning.
また、排紙補助トレイは、拡張位置と収納位置との間で移動可能に設けられているため、前記底板上への被記録媒体の補給等の妨げとならないように、不要なときには排紙補助トレイを収納することができる。   In addition, since the paper discharge auxiliary tray is movably provided between the extended position and the storage position, a paper discharge auxiliary tray is provided when it is unnecessary so as not to hinder the supply of the recording medium onto the bottom plate. Tray can be stored.
また、排紙補助トレイを収納するために前記底板に凹設された第1収納部には、被記録媒体の下方への撓みを規制する規制部が設けられているため、底板に載置されている被記録媒体に撓み癖等が付くことを防止でき、搬送不良や記録品質の悪化を招く心配もない。   In addition, the first storage portion recessed in the bottom plate for storing the paper discharge auxiliary tray is provided with a restricting portion for restricting the downward deflection of the recording medium, so that it is placed on the bottom plate. Therefore, it is possible to prevent the recording medium from being bent or wrinkled, and there is no fear of causing a conveyance failure or a deterioration in recording quality.

給紙カセット3の奥側(図2において右側)には、用紙分離用に傾斜分離板8が配置されている。この傾斜分離板8は、用紙Pの幅方向(Y軸方向)の中央側で突出し、用紙Pの幅方向の左右両端部側に行くに従って後退するように平面視で凸湾曲状に形成されており、且つ用紙Pの幅方向の中央部には、用紙Pの先端縁に当接して分離を促進するための鋸歯状の弾性分離パッド8a(図5〜図9参照)が設けられている。   On the back side (right side in FIG. 2) of the paper feed cassette 3, an inclined separation plate 8 is disposed for paper separation. The inclined separation plate 8 is formed in a convex curve shape in plan view so as to protrude at the center side in the width direction (Y-axis direction) of the paper P and to recede toward the left and right ends in the width direction of the paper P. In addition, a serrated elastic separation pad 8 a (see FIGS. 5 to 9) for abutting the leading edge of the paper P to promote separation is provided at the center in the width direction of the paper P.
また、ハウジング2側には、給紙手段6における給紙アーム6aの基端部が上下方向に回動可能に装着され、この給紙アーム6aの先端部に設けられた給紙ローラ6bには、給紙アーム6a内に設けられた歯車伝達機構6cにより、図示しない駆動源からの回転が伝えられる。そして、この給紙ローラ6bと傾斜分離板8の弾性分離パッド8aとにより、給紙カセット3に堆積された用紙Pを一枚ずつ分離搬送する。給紙方向(矢印A方向)に沿って進むように分離された用紙Pは、搬送経路として、横向きの略U字形状のパスを含む給送路9を介して、給紙カセット3より上側(高い位置)に設けられた記録部7に給送される。給送路9は、そのU字形状の外周側を構成する第1搬送路体60と、内周側を構成する第2搬送路体52との間隙に形成されている。   Further, on the housing 2 side, a base end portion of a paper feeding arm 6a in the paper feeding means 6 is mounted so as to be rotatable in the vertical direction, and a paper feeding roller 6b provided at a tip portion of the paper feeding arm 6a The rotation from a drive source (not shown) is transmitted by a gear transmission mechanism 6c provided in the paper feed arm 6a. The paper P accumulated in the paper feed cassette 3 is separated and conveyed one by one by the paper feed roller 6b and the elastic separation pad 8a of the inclined separation plate 8. The paper P separated so as to proceed in the paper feeding direction (arrow A direction) is located above the paper feeding cassette 3 via a feeding path 9 including a substantially U-shaped path in the horizontal direction as a conveyance path ( It is fed to the recording unit 7 provided at a high position. The feeding path 9 is formed in a gap between the first transport path body 60 that forms the U-shaped outer peripheral side and the second transport path body 52 that forms the inner peripheral side.
なお、この実施形態では、給紙部11から記録部7側へ用紙Pを分離搬送する給紙方向(矢印A方向)と、記録部7から搬送された用紙Pを後述する排紙部10から排出する排紙方向(矢印B方向)とは、逆向きに設定されている。そして、これら給紙方向(矢印A方向)及び排紙方向(矢印B方向)に直交する方向(Y軸方向)を幅方向と記載する。   In this embodiment, the paper feeding direction (arrow A direction) for separating and transporting the paper P from the paper feeding unit 11 to the recording unit 7 side, and the paper P transported from the recording unit 7 from the paper discharge unit 10 described later. The paper discharge direction (direction of arrow B) is set in the opposite direction. A direction (Y-axis direction) perpendicular to the paper feeding direction (arrow A direction) and the paper discharge direction (arrow B direction) is referred to as a width direction.
記録部7は、図2及び図3に示されるように、箱型のメインフレーム21とその左右一対の側板21aにて支持され、Y軸方向(主走査方向)に延びる横長の板状の第1および第2ガイド部材22,23との間に形成される。記録部7におけるインクジェット式の記録ヘッド4が搭載されたキャリッジ5は、排紙方向(矢印B方向)の上流側の第1ガイド部材22及び下流側の第2ガイド部材23に跨って摺動自在に支持されているため、Y軸方向に往復移動可能になっている。   As shown in FIGS. 2 and 3, the recording unit 7 is supported by a box-shaped main frame 21 and a pair of left and right side plates 21a, and extends in the Y-axis direction (main scanning direction). It is formed between the first and second guide members 22 and 23. The carriage 5 on which the ink jet recording head 4 is mounted in the recording unit 7 is slidable across the first guide member 22 on the upstream side and the second guide member 23 on the downstream side in the paper discharge direction (arrow B direction). Therefore, it can be reciprocated in the Y-axis direction.
キャリッジ5を往復移動させるために、排紙方向(矢印B方向)の下流側に配置された第2ガイド部材23の上面には、主走査方向(Y軸方向)に延びるようにタイミングベルト24が配置され、このタイミングベルト24を駆動するCR(キャリッジ)モータ(図示せず)は第2ガイド部材23の下面に固定されている。   In order to reciprocate the carriage 5, a timing belt 24 extends on the upper surface of the second guide member 23 disposed on the downstream side in the paper discharge direction (arrow B direction) so as to extend in the main scanning direction (Y-axis direction). A CR (carriage) motor (not shown) that is disposed and drives the timing belt 24 is fixed to the lower surface of the second guide member 23.
キャリッジ5における記録ヘッド4の下面と対峙するようにY軸方向に延びる扁平状のプラテン26は、前記両ガイド部材22,23の間にて、メインフレーム21に固定されている(図3参照)。   A flat platen 26 extending in the Y-axis direction so as to face the lower surface of the recording head 4 in the carriage 5 is fixed to the main frame 21 between the guide members 22 and 23 (see FIG. 3). .
プラテン26の排紙方向(矢印B方向)上流側には、図2に示すように、用紙Pを記録ヘッド4の下面に搬送するための搬送(レジスト)ローラとして、駆動ローラ50と、この駆動ローラ50に対向する下方にニップローラ51とが配置されている。また、プラテン26の排紙方向(矢印B方向)下流側には、記録部7を経た用紙Pを排紙方向(矢印B方向)に沿って排紙部10に搬送するように駆動される排紙ローラ28と、これに対向して排紙ローラ28側に付勢された拍車ローラ(図示せず)とが配置されている。   As shown in FIG. 2, on the upstream side of the sheet discharge direction (arrow B direction) of the platen 26, as shown in FIG. A nip roller 51 is disposed below the roller 50. Further, on the downstream side of the platen 26 in the paper discharge direction (arrow B direction), the paper P that has passed through the recording unit 7 is discharged so as to be conveyed to the paper discharge unit 10 along the paper discharge direction (arrow B direction). A paper roller 28 and a spur roller (not shown) urged toward the paper discharge roller 28 are disposed opposite to the paper roller 28.
記録部7にて記録された用紙Pがその記録面を上向きにして排出される排紙部10は、給紙部11の上方に配置され、排紙部10に連通する排紙口10aがハウジング2の前面の開口部2aと共通にして開口されている。そして、排紙部10から排紙方向(矢印B方向)に従って排紙された用紙Pは、開口部2aの内部側に位置する排紙トレイ10bに堆積収容される。また、排紙方向(矢印B方向)の下流側のガイド部材23の下面からハウジング2の前端の排紙口10aまでの間には、排紙トレイ10bの上方を覆うようにした合成樹脂製の仕切板(下カバー体)29が、ハウジング2と一体的に形成されている(図2参照)。   The paper discharge unit 10 on which the paper P recorded by the recording unit 7 is discharged with its recording surface facing upward is disposed above the paper supply unit 11, and a paper discharge port 10 a communicating with the paper discharge unit 10 is provided in the housing. 2 is opened in common with the front opening 2a. Then, the paper P discharged from the paper discharge unit 10 in the paper discharge direction (arrow B direction) is accumulated and accommodated in a paper discharge tray 10b located inside the opening 2a. Further, a synthetic resin made to cover the upper side of the paper discharge tray 10b is provided between the lower surface of the guide member 23 on the downstream side in the paper discharge direction (direction of arrow B) and the paper discharge port 10a at the front end of the housing 2. A partition plate (lower cover body) 29 is formed integrally with the housing 2 (see FIG. 2).
次に給紙カセット3について詳細に説明する。給紙カセット3には、図4〜図9に示すように、用紙Pを載置する底板31が備えられ、この底板31における給紙方向(矢印A方向)上流側には、給紙方向に沿う両側部に側板32、32が立設されている。そして、前述した排紙トレイ10bが、底板31に載置された用紙Pの給紙方向(矢印A方向)の上流側の一部を覆うように、両側板32、32に跨って着脱可能に取り付けられている。この排紙トレイ10bの排紙方向(矢印B方向)の下流側端部には、底板31上へ用紙Pを補給し易くするために、幅方向の中央部に、平面視略コ字状の切欠部43が形成されている。   Next, the paper feed cassette 3 will be described in detail. As shown in FIGS. 4 to 9, the paper feed cassette 3 is provided with a bottom plate 31 on which the paper P is placed. The upstream side of the bottom plate 31 in the paper feed direction (arrow A direction) is the paper feed direction. Side plates 32 and 32 are erected on both side portions. The paper discharge tray 10b described above is detachable across both side plates 32 and 32 so as to cover a part of the upstream side in the paper feeding direction (arrow A direction) of the paper P placed on the bottom plate 31. It is attached. At the downstream end of the paper discharge tray 10b in the paper discharge direction (arrow B direction), in order to make it easy to replenish the paper P onto the bottom plate 31, a central portion in the width direction is substantially U-shaped in plan view. A notch 43 is formed.
また、底板31における給紙方向(矢印A方向)下流側には、用紙Pを給紙カセット3の幅方向の中心に対して左右対称にセットするための用紙幅ガイド45が左右方向(幅方向)に伸縮するように移動可能に配置されている。   Further, on the downstream side of the sheet feeding direction (arrow A direction) in the bottom plate 31, a sheet width guide 45 for setting the sheet P symmetrically with respect to the center of the sheet cassette 3 in the width direction is provided in the left-right direction (width direction). ) Is movably arranged to expand and contract.
底板31の給紙方向(矢印A方向)の上流側端部における幅方向の中央部には、この上流側端部からさらに外方(排紙方向のさらに下流側)へスライド可能に、略板状の補助支持部材33が設けられ、この補助支持部材33に排紙補助トレイ35が取り付けられている。この排紙補助トレイ35は、排紙トレイ10bから外方へ突出した用紙Pにおける排紙方向(矢印B方向)下流側の端部を支持することができるようになっている(図2参照)。   At the center in the width direction at the upstream end of the sheet feeding direction (arrow A direction) of the bottom plate 31, it is slidable further outward (further downstream in the paper discharge direction) from this upstream end. The auxiliary support member 33 is provided, and the auxiliary discharge member 35 is attached to the auxiliary support member 33. The paper discharge auxiliary tray 35 can support the downstream end of the paper P protruding outward from the paper discharge tray 10b in the paper discharge direction (arrow B direction) (see FIG. 2). .
補助支持部材33には、その給紙方向(矢印A方向)の上流側端部近傍に、上面に開口を有する第1収納部34が凹設されている。排紙補助トレイ35は、第1収納部34に収納される収納位置(図4、図6(b)及び図7(b)参照)と、底板31の給紙方向(矢印A方向)上流側の端部よりも排紙方向(矢印B方向)に近づくように伸びる拡張位置(図1、図5、図6(a)及び図7(a)参照)との間で移動可能に設けられており、拡張位置にあるときに、前述したように、外方へ突出した用紙Pを支持することができる。   In the auxiliary support member 33, a first storage portion 34 having an opening on the upper surface is recessed in the vicinity of the upstream end portion in the paper feeding direction (arrow A direction). The discharge auxiliary tray 35 is stored in the first storage portion 34 (see FIGS. 4, 6B and 7B), and upstream of the sheet feeding direction (arrow A direction) of the bottom plate 31. It is provided so as to be movable between an extended position (see FIGS. 1, 5, 6A and 7A) extending so as to be closer to the paper discharge direction (arrow B direction) than the end of the sheet. Thus, when in the extended position, the paper P protruding outward can be supported as described above.
また、補助支持部材33には、これをスライド移動させる際にユーザが把持し易いように、第1収納部34よりもさらに給紙方向(矢印A方向)の上流側端部に、把持用開口部42が板面を貫通して形成されている。   Further, the auxiliary support member 33 has a grip opening at the upstream end in the paper feeding direction (arrow A direction) further than the first storage portion 34 so that the user can easily grip the auxiliary support member 33 when sliding it. The portion 42 is formed through the plate surface.
排紙補助トレイ35は、その拡張位置では、補助支持部材33の把持用開口部42の給紙方向(矢印A方向)の上流側の内側部に当接することで、排紙方向(矢印B方向)の下流側が上流側より高くなる傾斜状態が維持される(図6(a)及び図7(a)参照)。このとき、排紙補助トレイ10bの排紙方向(矢印B方向)の下流側端部は、排紙トレイ10bの高さと略同じ高さまで上方に突出している。この傾斜状態により、上方に位置する排紙トレイ10bから突出した用紙Pの端部を受け止め易くなっている。また、把持用開口部42の内側部が、排紙補助トレイ35の傾斜状態の保持に利用されるので、前記傾斜状態を保持するための特別な構造の付加が不要となる。なお、排紙補助トレイ35の枢軸38(図5、図7参照)から遠い側の端部には、排紙補助トレイ35を回動させる際に、これを摘み易くするために、回動用切欠部46が設けられている(図6(a)及び図6(b)参照)。   In the extended position, the discharge auxiliary tray 35 abuts on the upstream inner side in the paper feeding direction (arrow A direction) of the gripping opening 42 of the auxiliary support member 33, so that the paper discharge direction (arrow B direction). ) Is maintained in an inclined state in which the downstream side is higher than the upstream side (see FIGS. 6A and 7A). At this time, the downstream end portion of the discharge auxiliary tray 10b in the discharge direction (arrow B direction) protrudes upward to substantially the same height as the discharge tray 10b. This inclined state makes it easy to receive the end of the paper P protruding from the paper discharge tray 10b positioned above. Further, since the inner portion of the gripping opening 42 is used to hold the discharge auxiliary tray 35 in an inclined state, it is not necessary to add a special structure for holding the inclined state. Note that a rotation notch is provided at the end of the discharge auxiliary tray 35 far from the pivot 38 (see FIGS. 5 and 7) so that the discharge auxiliary tray 35 can be easily picked when the auxiliary discharge tray 35 is rotated. A portion 46 is provided (see FIGS. 6A and 6B).
また、この排紙補助トレイ35が拡張位置にあるときに、底板31に載置された用紙Pの第1収納部34での下方への撓みを規制する規制部が備えられており、ここでは、規制部として、第1収納部34の底面に、上方に向かって突出し且つ給紙方向(矢印A方向)に沿って延びる第1突条部36が設けられている(図5、図6(a)及び図8(a)参照)。この第1突条部36は、補助支持部材33における補強用のリブとしても機能し、補助支持部材33の剛性を高めることができる。第1突条部36は、第1収納部34の底面における給紙方向(矢印A方向)の下流側に、幅方向に並んで2つ(一対)設けられている。第1突条部36はこの数に限定するものではないが、用紙Pの撓みを規制して安定的に支持するためには、複数本であることが望ましい。   Further, there is provided a restricting portion that restricts downward bending of the paper P placed on the bottom plate 31 in the first storage portion 34 when the auxiliary discharge tray 35 is in the extended position. As a restricting portion, a first protrusion portion 36 is provided on the bottom surface of the first storage portion 34 so as to protrude upward and extend along the paper feeding direction (arrow A direction) (FIGS. 5 and 6). a) and FIG. 8 (a)). The first protrusions 36 also function as reinforcing ribs in the auxiliary support member 33, and can increase the rigidity of the auxiliary support member 33. Two (a pair) of first protrusions 36 are provided side by side in the width direction on the downstream side of the sheet feeding direction (arrow A direction) on the bottom surface of the first storage portion 34. The number of the first protrusions 36 is not limited to this number, but it is desirable that the number of the first protrusions 36 be plural in order to restrict the bending of the paper P and stably support it.
排紙補助トレイ35には、その収納位置にて第1突条部36を遊嵌可能な長穴37が穿設されており、排紙補助トレイ35が第1収納部34に収納されているときに、長穴37から第1突条部36の上端が僅かに突出するようになっている(図6(b)及び図7(b参照)。換言すれば、排紙補助トレイ35が折り畳まれた状態で、第1突条部36の高さ内に配置されることになるので、高さ方向の占有スペースをコンパクトにできる。また、第1突条部36を、前述したように、第1収納部34の底面における給紙方向(矢印A方向)の下流側に設けることにより、排紙補助トレイ35に穿設される長穴37を、回動の支点となる枢軸38から離隔でき、排紙補助トレイ35の剛性の低下を防止している。   The discharge auxiliary tray 35 is provided with a long hole 37 into which the first protrusion 36 can be loosely fitted at the storage position, and the discharge auxiliary tray 35 is stored in the first storage portion 34. Sometimes, the upper end of the first protrusion 36 slightly protrudes from the elongated hole 37 (see FIGS. 6B and 7B). In other words, the discharge assist tray 35 is folded. In this state, it is arranged within the height of the first protrusion 36, so that the occupied space in the height direction can be made compact. By providing the bottom side of the first storage portion 34 on the downstream side in the paper feeding direction (in the direction of arrow A), the long hole 37 formed in the paper discharge auxiliary tray 35 can be separated from the pivot 38 serving as a pivot point of rotation. The rigidity of the discharge auxiliary tray 35 is prevented from being lowered.
補助支持部材33は、平面視長方形状で、底板31には、補助支持部材33の給紙方向(矢印A方向)に沿った両側部をスライド可能に挟持するととも、補助支持部材33を収納できる第2収納部39が形成されている(図5、図6(a)及び図8(a)参照)。補助支持部材33の第2収納部39への取り付けは、補助支持部材33の上面を前記両側部まで面一の平坦面に形成し、そのまま両側部が第2収納部39の内側面に設けられたスライド溝40に嵌め込まれる構造としており、単純形状によるコストダウンを図っている。従って、この実施形態では、補助支持部材33の上面は底板31の上面よりもわずかに低くなっている。   The auxiliary support member 33 has a rectangular shape in plan view, and the bottom plate 31 can slidably hold both side portions along the paper feeding direction (arrow A direction) of the auxiliary support member 33 and can accommodate the auxiliary support member 33. The 2nd accommodating part 39 is formed (refer FIG.5, FIG.6 (a) and FIG.8 (a)). The auxiliary support member 33 is attached to the second storage portion 39 by forming the upper surface of the auxiliary support member 33 on a flat surface that is flush with the both side portions, and the both side portions are provided on the inner side surface of the second storage portion 39 as they are. The structure is fitted in the slide groove 40, and the cost is reduced by a simple shape. Therefore, in this embodiment, the upper surface of the auxiliary support member 33 is slightly lower than the upper surface of the bottom plate 31.
そして、この補助支持部材33における第1収納部34の領域よりも幅方向の外側には、上方に向かって突出し且つ給送方向に沿って延びる第2突条部41が設けられている。この第2突条部41の上面の高さは、第1突条部36の上面の高さ及び給紙カセット3の底板31の上面の高さと略面一に形成されている。なお、厳密には、図6(a)及び図7(a)に示すように、補助支持部材33が底板31に対して給紙方向(矢印A方向)に向かって僅かに下ってスライドするようにスライド溝40が設けられているため、補助支持部材33が引き出された状態では、第1突条部36の上面及び第2突条部41の給紙方向(矢印A方向)下流側の上面が、底板31の上面と略面一であり(図7(a)参照)、補助支持部材33が第2収納部39に収納された状態では、第2突条部41の給紙方向(矢印A方向)上流側の上面が底板31の上面と略面一となるように構成されている(図7(b)参照)。従って、補助支持部材33が第2収納部39に収納されているときでも、底板31上の用紙Pは、第2突条部41によって、補助支持部材33の上面側へ撓むことなく支持されている。   And the 2nd protrusion 41 which protrudes upwards and extends along a feed direction is provided in the outer side of the width direction rather than the area | region of the 1st accommodating part 34 in this auxiliary | assistant support member 33. As shown in FIG. The height of the upper surface of the second ridge 41 is substantially flush with the height of the upper surface of the first ridge 36 and the height of the upper surface of the bottom plate 31 of the sheet feeding cassette 3. Strictly speaking, as shown in FIGS. 6A and 7A, the auxiliary support member 33 slides slightly with respect to the bottom plate 31 in the paper feeding direction (arrow A direction). Since the slide groove 40 is provided, the upper surface of the first protrusion 36 and the upper surface of the second protrusion 41 on the downstream side in the paper feeding direction (arrow A direction) when the auxiliary support member 33 is pulled out. Is substantially flush with the upper surface of the bottom plate 31 (see FIG. 7A), and in a state where the auxiliary support member 33 is housed in the second housing portion 39, the feeding direction of the second protrusion 41 (arrow) (A direction) It is comprised so that the upper surface of an upstream side may become substantially flush with the upper surface of the baseplate 31 (refer FIG.7 (b)). Accordingly, even when the auxiliary support member 33 is stored in the second storage portion 39, the paper P on the bottom plate 31 is supported by the second protrusion 41 without being bent toward the upper surface side of the auxiliary support member 33. ing.
第2突条部41は第1突条部36より給紙方向(矢印A方向)の長さが長く、この実施形態では、第1突条部36を挟んで2本(一対)設けられているが、第2突条部41の本数もこれに限定するものではない。   The second protrusion 41 is longer in the paper feeding direction (arrow A direction) than the first protrusion 36, and in this embodiment, two (a pair) are provided with the first protrusion 36 in between. However, the number of the second protrusions 41 is not limited to this.
また、第1突条部36及び第2突条部41における少なくとも給紙方向(矢印A方向)の下流側の各端部は、平面視において排紙トレイ10bの切欠部43の内側に位置し、その高さが下流側に向かって徐々に低くなるテーパ形状、いわゆる面取り形状に形成されている。すなわち、第1突条部36にテーパ形状部36aを、第2突条部41にテーパ形状部41aをそれぞれ設けている(図5、図6(a)及び図7(a)参照)。これは、用紙Pが、例えば、ハガキサイズ等の比較的小さいサイズである場合に、その排紙方向(矢印B方向)の下流側端部が、切欠部43から下方に落ち込んでも、用紙Pが、第1突条部36や第2突条部41の給紙方向(矢印A方向)下流側の角に引っ掛からないように配慮したものである。   In addition, at least each downstream end of the first protrusion 36 and the second protrusion 41 in the sheet feeding direction (arrow A direction) is located inside the notch 43 of the sheet discharge tray 10b in plan view. The taper has a height that gradually decreases toward the downstream side, that is, a so-called chamfered shape. That is, the taper-shaped part 36a is provided in the 1st protrusion part 36, and the taper-shaped part 41a is each provided in the 2nd protrusion part 41 (refer FIG.5, FIG.6 (a) and FIG.7 (a)). For example, when the paper P is a relatively small size such as a postcard size, even if the downstream end in the paper discharge direction (arrow B direction) falls downward from the notch 43, the paper P The first protrusion 36 and the second protrusion 41 are designed so as not to get caught in the downstream corner of the sheet feeding direction (arrow A direction).
上記構成によると、給紙カセット3に、リーガルサイズ等の給紙方向(矢印A方向)の長さサイズが長い用紙Pを堆積収容する場合には、ユーザが給紙カセット3の把持用開口部42を把持して補助支持部材33を底板31の第2収納部39から引き出すとともに、補助支持部材33の回動用切欠部46に指を掛けて、第1収納部34から排紙補助トレイ35を回動開放し、排紙補助トレイ35を傾斜状態となる拡張位置に移動させる(図5、図6(a)及び図7(a)参照)。   According to the above configuration, when the sheet P having a long length in the sheet feeding direction (arrow A direction) such as the legal size is accumulated and accommodated in the sheet feeding cassette 3, the user opens the grip opening of the sheet feeding cassette 3. 42, the auxiliary support member 33 is pulled out from the second storage portion 39 of the bottom plate 31, and a finger is put on the turning notch portion 46 of the auxiliary support member 33, so that the discharge auxiliary tray 35 is removed from the first storage portion 34. The rotation is released, and the discharge assist tray 35 is moved to the extended position where it is inclined (see FIGS. 5, 6A and 7A).
そして、画像記録の指令に基づいて、給紙カセット3の底板31に載置された用紙Pが、1枚ずつ給紙方向(矢印A方向)に向かって分離され、略U字形状のパスを含む給送路9を介して記録部7に搬送される。そして、記録部7を経た用紙Pは、排紙方向(矢印B方向)に沿って、排紙部10から排出され、排紙トレイ10b上に堆積される。   Based on the image recording command, the sheets P placed on the bottom plate 31 of the sheet feeding cassette 3 are separated one by one in the sheet feeding direction (arrow A direction), and a substantially U-shaped path is passed. It is conveyed to the recording unit 7 through the feeding path 9 that includes it. Then, the paper P that has passed through the recording unit 7 is discharged from the paper discharge unit 10 along the paper discharge direction (arrow B direction) and is deposited on the paper discharge tray 10b.
この用紙Pは長さ寸法が長いために、用紙Pの後端(排紙方向上流側端部)が排紙ローラ28との当接から開放される時点で、その前端(排紙方向下流側端部)が排紙トレイ10bから突出する位置にまで搬送されている。このとき、排紙補助トレイ35が、排紙トレイ10bよりも下方に位置する給紙カセット3を基端側とし、先端側が排紙トレイ10bの高さと略同じ高さまで上方に突出しているから、排紙トレイ10bからはみ出した用紙Pの前端は、下方に垂れ下がることなく、排紙補助トレイ35に受け止められる(図1参照)。これにより、排紙部10から排出された用紙Pは、排紙トレイ10bと排紙補助トレイ35とに跨って支持され、排出されてきた用紙Pが順次、安定的に積層堆積され、排紙トレイ10bからの脱落で、堆積順序が乱れるという不都合を生じる心配はない。   Since the length of the paper P is long, when the rear end (upstream end of the paper discharge direction) of the paper P is released from contact with the paper discharge roller 28, the front end (downstream of the paper discharge direction). The end portion is conveyed to a position protruding from the paper discharge tray 10b. At this time, the paper discharge auxiliary tray 35 has the paper feed cassette 3 positioned below the paper discharge tray 10b as the base end side, and the front end side protrudes upward to substantially the same height as the paper discharge tray 10b. The front end of the paper P protruding from the paper discharge tray 10b is received by the paper discharge auxiliary tray 35 without hanging down (see FIG. 1). Thus, the paper P discharged from the paper discharge unit 10 is supported across the paper discharge tray 10b and the paper discharge auxiliary tray 35, and the discharged paper P is sequentially and stably stacked and deposited. There is no fear of dropping the tray 10b causing the inconvenience that the order of deposition is disturbed.
一方、給紙カセット3における第1収納部34では、排紙補助トレイ35が拡張位置にあるため、底板31に凹状面が露出し、また補助支持部材33の上面が底板31よりも低くなっている。しかしながら、第1突条部36及び第2突条部41が、底板31と略面一の高さに凸設されているから、図8(a)に示すように、用紙Pが支持され、用紙Pが第1収納部34の内側や補助支持部材33の上面に落ち込んで撓むことを防止できる。   On the other hand, in the first storage section 34 of the paper feed cassette 3, since the discharge auxiliary tray 35 is in the extended position, the concave surface is exposed on the bottom plate 31, and the upper surface of the auxiliary support member 33 is lower than the bottom plate 31. Yes. However, since the first protrusion 36 and the second protrusion 41 are provided so as to be substantially flush with the bottom plate 31, the paper P is supported as shown in FIG. It is possible to prevent the sheet P from falling and bending inside the first storage portion 34 or the upper surface of the auxiliary support member 33.
仮に、第1突条部36や第2突条部41が設けられていない場合には、図8(b)に示すように、用紙Pが第1収納部34の内部や補助支持部材33の上面に落ち込んで撓む。その結果、給紙カセット3に長時間収容されている用紙Pには撓み癖がつくので、給紙手段6が用紙Pを重送したり、搬送の途中で皺や紙ジャム(紙詰まり)を発生することが懸念される。また、撓み癖がついたまま記録部7に搬送されると、用紙Pの上面と記録ヘッド4との距離が部分的に異なり、特に本実施形態のように記録ヘッド4がインクジェット式の場合には、記録品質に大きな悪影響を与えることになる。   Temporarily, when the 1st protrusion part 36 and the 2nd protrusion part 41 are not provided, as shown in FIG.8 (b), the paper P is the inside of the 1st accommodating part 34, or the auxiliary | assistant support member 33. It falls on the top surface and bends. As a result, the paper P stored in the paper feed cassette 3 for a long time has a bending wrinkle, so that the paper feeding means 6 double feeds the paper P or causes paper jam or paper jam (paper jam) during the transportation. There are concerns about the occurrence. Further, when the sheet is conveyed to the recording unit 7 with a bending wrinkle, the distance between the upper surface of the paper P and the recording head 4 is partially different, particularly when the recording head 4 is an ink jet type as in this embodiment. This will have a large adverse effect on the recording quality.
また、給紙カセット3に、例えばA4サイズ、レターサイズ、はがきサイズ等の用紙Pを堆積収容する場合には、排紙補助トレイ35は第1収納部34に収納され、補助支持部材33は第2収納部39に収納される。なお、必要に応じて、排紙補助トレイ35を拡張位置にしたまま、補助支持部材33を第2収納部39に収納したり、排紙補助トレイ35を収納位置にしたまま、補助支持部材33を引き出したりしてもよく、これらは適宜組み合せて設定できる。   Further, when the paper cassette 3 stores, for example, A4 size, letter size, postcard size paper P, etc., the paper discharge auxiliary tray 35 is stored in the first storage portion 34, and the auxiliary support member 33 is the first support member 33. 2 is stored in the storage unit 39. If necessary, the auxiliary support member 33 is stored in the second storage portion 39 while the discharge auxiliary tray 35 is in the extended position, or the auxiliary support member 33 is set while the discharge auxiliary tray 35 is in the storage position. May be pulled out, and these can be set in combination as appropriate.
なお、上記実施形態では、排紙補助トレイ35が、給紙カセット3の補助支持部材33に設けられている形態について説明したが、図9に示すように、補助支持部材33が給紙カセット3に無い場合には、排紙補助トレイ35を給紙カセット3の底板31に、直接取り付けてもよい。なお、図9においては、上記実施形態の給紙カセット3と同一の構成部材には同一の番号が付されている。   In the embodiment described above, the discharge auxiliary tray 35 is provided on the auxiliary support member 33 of the paper feed cassette 3. However, as shown in FIG. 9, the auxiliary support member 33 is provided on the paper feed cassette 3. If not, the auxiliary discharge tray 35 may be directly attached to the bottom plate 31 of the paper feed cassette 3. In FIG. 9, the same reference numerals are given to the same components as those of the paper feed cassette 3 of the above embodiment.
また、上記実施形態では、排紙補助トレイ35の移動は、回動により行うように構成しているが、スライド移動するように構成してもよい。その場合には、長穴37の代わりに細長形状の切欠部が形成される。   Further, in the above embodiment, the discharge auxiliary tray 35 is moved by rotation, but may be configured to slide. In that case, an elongated cutout is formed instead of the elongated hole 37.
また、本発明は、上述したような給紙カセットが1段のみの構成に適用するだけでなく、上下に複数段の給紙カセットを備える画像記録装置において、排紙部に最も近い最上段の給紙カセットに適用してもよい。   In addition, the present invention is not only applied to a configuration in which the paper feed cassette described above is only one stage, but also in an image recording apparatus having a plurality of paper feed cassettes on the upper and lower sides, the uppermost stage closest to the paper discharge unit. You may apply to a paper feed cassette.
