Description

本願発明は、給紙トレイ上に積載された原稿を所定の位置に繰り出す給紙装置に係り、特に原稿を繰出手段に圧接させるため昇降自在な昇降トレイを備えた給紙装置に関するものである。   The present invention relates to a paper feeding device that feeds a document stacked on a paper feeding tray to a predetermined position, and more particularly to a paper feeding device including a lifting tray that can be raised and lowered to press the document against a feeding means.

画像読取装置や複写機等に備えられて原稿を所定の画像読取位置に搬送する給紙装置において、給紙トレイの下方に排紙トレイを配置し、給紙トレイ上に載置された原稿を画像読取位置を介して排紙トレイに搬送するための搬送パスをU字状に形成したものが知られている。この種の給紙装置では、排紙トレイから原稿を取り出したり、排紙部でジャムした原稿を取り除くことができるように、給紙トレイを上方に回動できるように構成してある。また、近年の給紙装置においては、給紙トレイの下方に設けられた排紙部にスタンパーやプリンターなどを取り付けて原稿にマークやメッセージを表示させるものがあり、このような装置ではスタンパーやプリンターのメンテナンスも必要であるため、給紙トレイの全体を上方に回動させて排紙部を完全に露出させることが望まれている。   In a paper feeding device that is provided in an image reading device, a copying machine, or the like and transports a document to a predetermined image reading position, a paper discharge tray is disposed below the paper feeding tray, and a document placed on the paper feeding tray is 2. Description of the Related Art There is a known U-shaped transport path for transporting to a paper discharge tray via an image reading position. In this type of paper feeding device, the paper feed tray can be rotated upward so that the original can be taken out from the paper discharge tray or the paper jammed in the paper discharge unit can be removed. In addition, in recent paper feeding apparatuses, there are some paper stamps and printers that are attached to a paper discharge unit provided below the paper feed tray to display marks and messages on the original. Therefore, it is desired to completely expose the paper discharge unit by rotating the entire paper feed tray upward.

一方、最近は大量の原稿を一度に取り扱える給紙装置が望まれており、その種の給紙装置としては、原稿の後端側を支持する給紙トレイと原稿の先端側を支持する昇降自在な昇降トレイとで構成された給紙トレイユニットを採用したものが知られている(特許文献1及び特許文献2参照)。昇降トレイは、その一端側が給紙トレイに回動自在に支持され、他端側がフリーの状態になっている。また、昇降トレイの背面側には昇降レバーとこの昇降レバーの駆動モータなどで構成される昇降手段が設けられており、駆動モータによって回動させた昇降レバーで昇降トレイの背面を押し上げて昇降トレイを上昇させる構成となっている。なお、駆動モータを逆回転させ昇降レバーを昇降トレイの背面から離れる方向に回動させることで、昇降トレイはその自重によって下降する。   On the other hand, recently, a paper feeding device that can handle a large amount of originals at once is desired. As such a paper feeding device, a paper feeding tray that supports the rear end side of the original and a freely movable up and down that supports the front end side of the original are provided. There is known one that employs a paper feed tray unit composed of a simple lifting tray (see Patent Document 1 and Patent Document 2). One end of the elevating tray is rotatably supported by the paper feed tray, and the other end is in a free state. Also, on the back side of the lift tray, a lift means composed of a lift lever and a drive motor for the lift lever is provided. The lift tray is pushed up by the lift lever rotated by the drive motor. It is the composition which raises. The lift tray is lowered by its own weight by rotating the drive motor in the reverse direction and rotating the lift lever away from the back surface of the lift tray.

しかしながら、上記のように昇降トレイを備えた給紙トレイユニットにあっては、前述のように、昇降トレイは給紙トレイに対して一端側のみが支持され、他端側がフリーの状態になっているために、給紙トレイユニットの全体を上方に回動させた場合、昇降トレイは給紙トレイに垂れ下がった状態で保持されることになる。そのために、給紙トレイユニットの回動時に昇降トレイが揺動して給紙トレイや他の部品などに当たって不快音を発生させたり、部品を傷付けるといった問題があった。
特開2003−118851号公報 特開2001−139162号公報
However, in the paper feed tray unit having the lift tray as described above, as described above, the lift tray is supported only on one end side with respect to the paper feed tray, and the other end side is in a free state. For this reason, when the entire paper feed tray unit is rotated upward, the lifting tray is held in a state of hanging from the paper feed tray. For this reason, there has been a problem that the lifting tray swings when the paper feed tray unit is rotated and hits the paper feed tray or other parts to generate unpleasant noise or damage the parts.
Japanese Patent Laid-Open No. 2003-118851 JP 2001-139162 A

本発明が解決しようとする問題点は、給紙トレイユニットの全体を上方に回動させた際に、昇降トレイの揺動によって不快音が発生したり部品が傷付くのを防止することである。   The problem to be solved by the present invention is to prevent an unpleasant noise or a component from being damaged by the swinging of the lifting tray when the entire sheet feeding tray unit is rotated upward. .

本発明に係る給紙装置は、原稿の一端側が載置される給紙トレイ及び原稿の他端側が載置され且つ前記給紙トレイに昇降自在に支持される昇降トレイからなる給紙トレイユニットと、前記給紙トレイユニット上の原稿を繰り出す繰出手段を有する搬送ユニットとを備え、前記給紙トレイユニットが前記搬送ユニットに対して回動可能に支持されてなる給紙装置において、前記給紙トレイユニットを原稿載置位置から上方に回動させた際に、給紙トレイに対して昇降トレイの動きを拘束する規制手段を設けたことを特徴とする。   A sheet feeding device according to the present invention includes a sheet feeding tray unit including a sheet feeding tray on which one end side of a document is placed, and a lifting tray on which the other end side of the document is placed and supported so as to be movable up and down on the sheet feeding tray. A feeding unit having a feeding unit for feeding out the original on the feeding tray unit, wherein the feeding tray unit is rotatably supported with respect to the feeding unit. When the unit is rotated upward from the document placement position, there is provided a restricting means for restricting the movement of the lifting tray with respect to the paper feed tray.

本発明に係る給紙装置によれば、給紙トレイユニットを原稿載置位置から上方に回動させた際には昇降トレイの揺動が規制手段によって拘束されるので、従来のような昇降トレイの揺動による不快音の発生や、昇降トレイと他の部品との衝突による傷つきを防止することができる。   According to the paper feeding device of the present invention, when the paper feeding tray unit is rotated upward from the document placement position, the swinging of the lifting tray is restrained by the restricting means. It is possible to prevent generation of unpleasant noise due to swinging of the head and damage due to collision between the lifting tray and other parts.

以下、添付図面に基づいて本発明に係る給紙装置の実施形態を詳細に説明する。図1は画像読取装置に搭載された本発明の給紙装置を示す断面図である。図1において、Aは画像読取装置Hの上部に搭載された給紙装置としての原稿送り装置であり、この原稿送り装置Aは、画像読取装置Hの上面に設けられた第1のコンタクトガラス1上を原稿が通過するように搬送する。   Hereinafter, embodiments of a sheet feeding device according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing a paper feeding device of the present invention mounted on an image reading device. In FIG. 1, A is a document feeding device as a paper feeding device mounted on the upper portion of the image reading device H. This document feeding device A is a first contact glass 1 provided on the upper surface of the image reading device H. The document is conveyed so that it passes through the top.

画像読取装置Hは、第1のコンタクトガラス1を介してランプ等の光源から発せられた光を原稿に照射し、その反射光を複数のミラーで反射させ、レンズを介してCCDなどの光電変換手段により光電変換して原稿画像を読み取る第1の読取ユニット3を備え、第1のコンタクトガラス1の上面に画像読取装置Hの第1の読取部5を構成している。また、画像読取装置Hは、前記第1のコンタクトガラス1の後方に第2のコンタクトガラス2を備えている。この第2のコンタクトガラス2は、原稿を載せ置くことのできる面積を備えており、原稿送り装置Aを上方に開けて第2のコンタクトガラス2上に本や雑誌等の厚い原稿を載せ置き、前記第1の読取ユニット3を副走査方向に移動させることによって、原稿画像を読み取ることができる。   The image reading apparatus H irradiates a document with light emitted from a light source such as a lamp through the first contact glass 1, reflects the reflected light with a plurality of mirrors, and performs photoelectric conversion such as a CCD through a lens. The first reading unit 3 that reads the original image by photoelectric conversion by means is provided, and the first reading unit 5 of the image reading apparatus H is configured on the upper surface of the first contact glass 1. Further, the image reading apparatus H includes a second contact glass 2 behind the first contact glass 1. The second contact glass 2 has an area on which a document can be placed. The document feeder A is opened upward to place a thick document such as a book or magazine on the second contact glass 2. The original image can be read by moving the first reading unit 3 in the sub-scanning direction.

原稿送り装置Aは、大量の原稿を一度に載置することのできる給紙トレイユニットTと、この給紙トレイユニットTの下方側に配置され、前記画像読取装置Hで原稿画像が読み取られた原稿を収納する排紙トレイ11と、前記第2のコンタクトガラス2を押圧するための押圧カバー12と、前記給紙トレイユニットTから排紙トレイ11に原稿を搬送するためのU字状の搬送パス13とを備えて構成されている。前記押圧カバー12は、例えばスポンジ等の多孔質部材と白色マイラー等のフィルム部材とによって構成されている。   The document feeder A is disposed on a lower side of the paper feed tray unit T on which a large amount of documents can be placed at one time, and a document image is read by the image reading device H. A paper discharge tray 11 for storing a document, a pressure cover 12 for pressing the second contact glass 2, and a U-shaped transport for transporting a document from the paper feed tray unit T to the paper discharge tray 11 And a path 13. The pressing cover 12 is composed of, for example, a porous member such as sponge and a film member such as white mylar.

また、この実施形態における原稿送り装置Aでは、前記U字状の搬送パス13の湾曲部に原稿の裏面画像を読み取る第2の読取ユニット4が設けられている。この第2の読取ユニット4は、前記第1の読取ユニット3と同様、搬送パス13の一部を形成するコンタクトガラス7を介してランプ等の光源から発せられる光を原稿に照射し、その反射光を複数のミラーで反射させてレンズを介してCCDなどの光電変換手段により光電変換して原稿画像を読み取るように構成されており、コンタクトガラス7の上面が画像読取装置Hの第2の読取部6として構成される。このように、上記の原稿送り装置Aでは、搬送パス13途中の第2の読取部6を通過する原稿の一方の片面の原稿画像を第2の読取ユニット4で読み取り、第1の読取部5を通過する原稿の他方の片面の原稿画像を第1の読取ユニット3で読み取るので、両面原稿の画像読取時間を大幅に短縮することができる。   Further, in the document feeder A in this embodiment, the second reading unit 4 that reads the back side image of the document is provided on the curved portion of the U-shaped conveyance path 13. Similar to the first reading unit 3, the second reading unit 4 irradiates a document with light emitted from a light source such as a lamp via a contact glass 7 that forms a part of the transport path 13, and reflects the reflected light. Light is reflected by a plurality of mirrors and photoelectrically converted by a photoelectric conversion means such as a CCD through a lens to read an original image. The upper surface of the contact glass 7 is the second reading of the image reading device H. The unit 6 is configured. As described above, in the above document feeder A, the document image on one side of the document passing through the second reading unit 6 in the middle of the conveyance path 13 is read by the second reading unit 4 and the first reading unit 5 is read. Since the first reading unit 3 reads the original image on the other side of the original passing through the document, the image reading time for the double-sided original can be greatly shortened.

前記U字状の搬送パス13は、給紙トレイユニットTから原稿を繰り出すための繰出ローラ21と、繰出ローラ21から繰り出された原稿を1枚ずつ分離して給送するための給紙ローラ22及び分離パッド23からなる分離手段と、給紙ローラ22から給紙された原稿の先端がそのニップ点に突き当たることによって原稿の先端を整合してスキューを除去し、その後に駆動して原稿を下流側に送るレジストローラ対24とを備える。また、搬送パス13は、前記レジストローラ対24からの原稿を前記第2の読取部6及び第1の読取部5に向けて送り出す送りローラ対25と、送りローラ対25からの原稿を第2の読取部6に供給する第1の読取ローラ対26と、第2の読取部6にて一方の片面が読み取られた原稿を第1の読取部5に供給する第2の読取ローラ対27とを備える。さらに、搬送パス13は、前記第2の読取部6と第1の読取部5とを通過した原稿を搬出する第3の読取ローラ対28と、第1の読取部5を通過して両面が読み取られた後の原稿を第3の読取ローラ対28から受けて排紙トレイ11に向けて搬送する第1排紙ローラ対29と、原稿を排紙トレイ11に排紙する第2排紙ローラ対30とを備えている。この実施形態では、上記の搬送パス13は複数の部材を組み込んだ搬送ユニットFとして構成されている。   The U-shaped transport path 13 includes a feeding roller 21 for feeding out the original from the paper feeding tray unit T, and a paper feeding roller 22 for separating and feeding the originals fed out from the feeding roller 21 one by one. And the separation means comprising the separation pad 23 and the leading edge of the document fed from the paper feed roller 22 abuts the nip point to align the leading edge of the document to remove the skew, and then drive the document downstream. And a registration roller pair 24 to be fed to the side. The conveyance path 13 also feeds a document from the registration roller pair 24 toward the second reading unit 6 and the first reading unit 5, and a document from the feeding roller pair 25 to the second. A first reading roller pair 26 to be supplied to the reading unit 6, and a second reading roller pair 27 to supply the first reading unit 5 with a document whose one surface is read by the second reading unit 6. Is provided. Further, the conveyance path 13 has a third reading roller pair 28 for carrying out the original document that has passed through the second reading unit 6 and the first reading unit 5, and both sides thereof passing through the first reading unit 5. A first paper discharge roller pair 29 that receives the read original from the third reading roller pair 28 and conveys the original toward the paper discharge tray 11, and a second paper discharge roller that discharges the original to the paper discharge tray 11. And a pair 30. In this embodiment, the conveyance path 13 is configured as a conveyance unit F incorporating a plurality of members.

次に、上記構成からなる原稿送り装置Aによる原稿搬送動作について説明する。先ず、給紙トレイユニットT上に原稿が載置されたことをエンプティセンサS1が検知し、さらに画像読取装置Hからの給紙指令信号によって、繰出ローラ21と給紙ローラ22とが駆動する。これによって、給紙トレイユニットTの上に載置された複数の原稿が順次繰り出され、分離パッド23によって1枚ずつ分離されたのち給送される。給送された原稿の先端をレジストセンサS2が検知すると、その検知した時点から原稿を所定量搬送することによって、レジストローラ対24のニップ部に原稿の先端が突き当たって整合され、スキューが取り除かれる。その後、レジストローラ対24、送りローラ対25及び各読取ローラ対26、27、28が駆動する。これによって、原稿はU字状の搬送パス13に沿ってその表裏が反転するように搬送され、第2の読取部6、第1の読取部5の順に通過する。この第2の読取部6を通過する時に原稿の一方の片面が読み取られ、第1の読取部5を通過する時に原稿の他方の片面が読み取られる。   Next, a document conveying operation by the document feeder A having the above configuration will be described. First, the empty sensor S1 detects that a document is placed on the paper feed tray unit T, and the feeding roller 21 and the paper feed roller 22 are driven by a paper feed command signal from the image reading device H. As a result, a plurality of documents placed on the sheet feed tray unit T are sequentially fed out, separated one by one by the separation pad 23, and then fed. When the registration sensor S2 detects the leading edge of the fed document, the document is transported by a predetermined amount from the point of detection, whereby the leading edge of the document abuts against the nip portion of the registration roller pair 24 to be aligned, and the skew is removed. . Thereafter, the registration roller pair 24, the feed roller pair 25, and the reading roller pairs 26, 27, and 28 are driven. As a result, the document is transported along the U-shaped transport path 13 so that the front and back thereof are reversed, and passes through the second reading unit 6 and the first reading unit 5 in this order. One side of the original is read when passing through the second reading unit 6, and the other side of the original is read when passing through the first reading unit 5.

原稿の先端が第1排紙ローラ対29に到達する前に、第1排紙ローラ対29と第2排紙ローラ対30とが駆動し、第2の読取部6と第1の読取部5とで両面が読み取られた原稿を排紙トレイ11上に排紙する。   Before the leading edge of the document reaches the first paper discharge roller pair 29, the first paper discharge roller pair 29 and the second paper discharge roller pair 30 are driven, and the second reading unit 6 and the first reading unit 5 are driven. Then, the document whose both sides are read is discharged onto the discharge tray 11.

なお、上述した原稿送り装置Aには、搬送パス13のレジストローラ対24と送りローラ対25との間の経路に重送検出センサGSが設けられている。この重送検出センサGSは、超音波を発振する発振部と超音波を受振する受振部とを経路を挟んで対向して配置されており、受振した超音波の振動レベルによって原稿の重送を検出する。また、搬送パス13の排紙トレイ11側の排紙部にはインプリンタ8が設けられている。このインプリンタ8は、第1排紙ローラ29と第2排紙ローラ30とによって排紙される原稿面に5文字程度の文字を印刷することができる。ここでは、原稿の重送などの搬送エラーや第1、第2の読取ユニット3、4による読取エラーが発生したことを報知する文字をエラーの発生した原稿に印刷するようになっている。   In the document feeder A described above, a double feed detection sensor GS is provided in the path between the registration roller pair 24 and the feed roller pair 25 in the transport path 13. This double feed detection sensor GS is arranged so that an oscillating unit that oscillates ultrasonic waves and a vibration receiving unit that receives ultrasonic waves are opposed to each other across a path, and performs double feeding of a document according to the vibration level of the received ultrasonic waves. To detect. Further, an imprinter 8 is provided in the paper discharge unit on the paper discharge tray 11 side of the transport path 13. The imprinter 8 can print about five characters on the document surface discharged by the first discharge roller 29 and the second discharge roller 30. Here, characters notifying that a transport error such as double feeding of documents and a reading error by the first and second reading units 3 and 4 have occurred are printed on the document in which the error has occurred.

次に、本発明における給紙トレイユニットTの構成及び作用について詳細に説明する。図2は給紙トレイユニットTの構成を説明するための斜視図、図3は給紙トレイユニットTの断面図である。   Next, the configuration and operation of the paper feed tray unit T in the present invention will be described in detail. FIG. 2 is a perspective view for explaining the configuration of the paper feed tray unit T, and FIG.

図2及び図3に示すように、本発明の給紙トレイユニットTは、原稿の後端側を支持する給紙トレイ41と、原稿の先端側を支持する昇降トレイ42とを備える。給紙トレイ41は、平板状の原稿載置部41aに、昇降トレイ42の底面側を覆うカバー部41bと給紙トレイユニットTを上方に回動するためのアーム部41cとが一体に形成されたものである。昇降トレイ42は、前記給紙トレイ41のカバー部41bの上方に配置された平板状の部材からなり、給紙トレイ41の原稿載置部41aと一連につながって原稿の先端側の載置面を形成する。また、昇降トレイ42の後端両側に設けた支持ピン42aが給紙トレイ41に回転可能に取り付けられている。そのため、昇降トレイ42は、図3に示されるような給紙トレイ41の原稿載置部41aと連続するフラット面を形成して原稿を載置するための載置位置と、図3に仮想線で示したように、支持ピン42aを支点して前方側が上昇して繰出ローラ21の周面に原稿の上面が接触する繰出位置との間を昇降する。   As shown in FIGS. 2 and 3, the paper feed tray unit T of the present invention includes a paper feed tray 41 that supports the rear end side of the original, and an elevating tray 42 that supports the front end side of the original. The paper feed tray 41 is integrally formed with a flat document placing portion 41 a and a cover portion 41 b that covers the bottom side of the elevating tray 42 and an arm portion 41 c for rotating the paper feed tray unit T upward. It is a thing. The elevating tray 42 is composed of a flat plate member disposed above the cover portion 41b of the paper feed tray 41, and is connected in series with the document placement portion 41a of the paper feed tray 41 to place the placement surface on the leading end side of the document. Form. Further, support pins 42 a provided on both sides of the rear end of the elevating tray 42 are rotatably attached to the paper feed tray 41. Therefore, the elevating tray 42 has a placement position for placing a document by forming a flat surface continuous with the document placement portion 41a of the sheet feed tray 41 as shown in FIG. As shown in FIG. 5, the support pin 42a is supported, and the front side is raised and moved up and down between the feeding position where the upper surface of the document contacts the peripheral surface of the feeding roller 21.

前記給紙トレイ41のカバー部41bは、昇降トレイ42の底面側を覆うことによって、後述する一対のサイド規制部材43の連動機構並びに昇降トレイ42を上昇させるための昇降レバー44が外部に露出しないようにしている。また、アーム部41cは、図2に示すようにその先端側に回動ピン41dを備え、この回動ピン41dがU字状の搬送パス13を構成する搬送ユニットFの側壁50に回動可能に取り付けられる。そのため、給紙トレイユニットTは、給紙トレイ41と昇降トレイ42とが一緒になって、回動ピン41dを支点として搬送ユニットFに対して上下方向に回動可能となる。給紙トレイユニットTを上方に回動させる場合としては、排紙トレイ11に排紙された原稿を取り出す場合やジャム原稿を取り除く場合などである。   The cover 41b of the paper feed tray 41 covers the bottom surface side of the lifting tray 42 so that the interlock mechanism of a pair of side regulating members 43 described later and the lifting lever 44 for raising the lifting tray 42 are not exposed to the outside. I am doing so. Further, as shown in FIG. 2, the arm portion 41 c is provided with a rotation pin 41 d at its distal end side, and this rotation pin 41 d can be rotated on the side wall 50 of the conveyance unit F constituting the U-shaped conveyance path 13. Attached to. Therefore, the paper feed tray unit T can be rotated in the vertical direction with respect to the transport unit F with the paper feed tray 41 and the lifting tray 42 together, with the rotation pin 41d as a fulcrum. Examples of the case where the paper feed tray unit T is rotated upward include a case where a document discharged to the paper discharge tray 11 is taken out and a case where a jammed document is removed.

また、上記昇降トレイ42には、原稿の幅方向の側端を規制する一対のサイド規制部材43が設けられている。このサイド規制部材43は原稿の幅方向の両側端を規制するために、幅方向にスライド移動自在に設けられており、一方のサイド規制部材のスライド移動に連動して他方のサイド規制部材がスライド移動するための連動機構が設けられている。なお、連動機構は図示しないが、ラックとピニオンを有する一般的な機構を採用している。   The elevating tray 42 is provided with a pair of side regulating members 43 that regulate the side edges of the document in the width direction. The side regulating member 43 is slidably movable in the width direction in order to regulate both side edges of the document in the width direction, and the other side regulating member slides in conjunction with the sliding movement of one side regulating member. An interlocking mechanism for moving is provided. Although the interlocking mechanism is not shown, a general mechanism having a rack and a pinion is adopted.

前記昇降トレイ42の昇降は搬送ユニットF側に設けられた昇降手段によって駆動される。この実施例において昇降手段は、昇降トレイ42の先端側の背面に当接する昇降レバー44と、この昇降レバー44を上下に回動する駆動軸45と、この駆動軸45に連結された駆動伝達手段としての複数のギヤ(図示せず)と、複数のギヤを介して駆動軸45を回転させる昇降モータ(図示せず)と、により構成されている。前記昇降レバー44は、図2に示したように、中央部に係合穴44aが開設された細長い平板部材であり、その先端部が昇降トレイ42の先端側の直下にまで延設して、昇降トレイ42の背面に当接する。   The raising / lowering of the raising / lowering tray 42 is driven by raising / lowering means provided on the transport unit F side. In this embodiment, the lifting / lowering means includes a lifting / lowering lever 44 that abuts on the rear surface on the front end side of the lifting / lowering tray 42, a drive shaft 45 that rotates the lifting / lowering lever 44 up and down, and a drive transmission means coupled to the drive shaft 45. As a plurality of gears (not shown), and a lifting motor (not shown) for rotating the drive shaft 45 via the plurality of gears. As shown in FIG. 2, the elevating lever 44 is an elongated flat plate member having an engagement hole 44a formed in the center, and its tip extends to the position just below the tip of the elevating tray 42, It abuts on the back surface of the lifting tray 42.

次に、昇降トレイ42の昇降動作について説明する。給紙トレイユニットTに載置された原稿をエンプティセンサS1が検出し、画像読取装置Hからの給紙指令信号によって昇降モータが正回転駆動を開始する。このモータの正回転駆動によって駆動軸45が回転し、下限位置にある昇降レバー44を上方に回動させる。この回動動作によって昇降レバー44の先端部が昇降トレイ42の背面に当接して昇降トレイ42を押し上げる。この動作に基づいて、昇降トレイ42は後端の支持ピン42aを回動支点として先端側が上昇する。なお、昇降モータは、昇降トレイ42に載置された原稿の最上面が繰出ローラ21に当接する繰出位置に達するまで昇降トレイ42が上昇した時に駆動を停止する。この状態で繰出ローラ21が駆動されて原稿が繰り出される。   Next, the raising / lowering operation | movement of the raising / lowering tray 42 is demonstrated. The empty sensor S1 detects the original placed on the paper feed tray unit T, and the lifting motor starts to rotate forward in response to a paper feed command signal from the image reading device H. The drive shaft 45 is rotated by the forward rotation of the motor, and the lifting lever 44 at the lower limit position is rotated upward. By this turning operation, the tip of the lift lever 44 comes into contact with the back surface of the lift tray 42 to push up the lift tray 42. Based on this operation, the elevating tray 42 rises at the front end side with the support pin 42a at the rear end as a pivot point. The elevating motor stops driving when the elevating tray 42 is raised until the uppermost surface of the document placed on the elevating tray 42 reaches a feeding position where it contacts the feeding roller 21. In this state, the feeding roller 21 is driven to feed the document.

その後、原稿が所定枚数繰り出される毎に昇降モータが駆動し、昇降レバー44によって昇降トレイ42が上昇して原稿の最上面が常時適正な繰出位置となるように制御される。そして、給紙トレイユニットT上に原稿が無くなったことをエンプティセンサS1で検出すると昇降モータが逆回転駆動を開始する。これによって、駆動軸45を介して昇降レバー44は下方に回動して下限位置まで移動する。この昇降レバー44の下方への回動に追従して昇降トレイ42は自重によって下方の載置位置まで下降する。なお、符号S4は原稿の最上面が繰り出し位置に到達したことを検出する繰出位置検出センサであり、符号S5は昇降レバー44が下限位置に移動したことを検出する下限位置センサである。なお、前記昇降レバー44に設けられた係合孔44aに、昇降トレイ42の背面に設けた突起(図示せず)を係合させることで、昇降レバー44の上昇時には給紙トレイユニットTの上方への回動を規制することができる。   Thereafter, the elevation motor is driven each time a predetermined number of documents are fed out, and the elevation tray 42 is raised by the elevation lever 44 so that the uppermost surface of the document is always at an appropriate feeding position. When the empty sensor S1 detects that there is no document on the paper feed tray unit T, the lift motor starts reverse rotation driving. As a result, the lifting lever 44 rotates downward via the drive shaft 45 and moves to the lower limit position. Following the downward rotation of the elevating lever 44, the elevating tray 42 is lowered to its lower placement position by its own weight. Reference numeral S4 is a feeding position detection sensor that detects that the uppermost surface of the document has reached the feeding position, and reference numeral S5 is a lower limit position sensor that detects that the elevating lever 44 has moved to the lower limit position. In addition, by engaging a protrusion (not shown) provided on the back surface of the lifting tray 42 with the engagement hole 44a provided in the lifting lever 44, the upper side of the paper feed tray unit T is raised when the lifting lever 44 is raised. Rotation to can be restricted.

本発明に係る原稿送り装置Aの特徴は、前記給紙トレイユニットTを上方に回動させた際に、給紙トレイ41に対する昇降トレイ42のガタ付きなどを防ぐ規制手段が設けられている点である。この実施形態における規制手段は、図4に示されるように、昇降トレイ42の先端側の背面に突出形成された係合部材としての係合突起60と、給紙トレイ41のカバー部41bに取り付けられた被係合部材としての規制部材61とを備える。この規制部材61は、給紙トレイユニットTを回動させた際に、前記係合突起60と係合して、昇降トレイ42の自由端側が揺動するのを防止するものである。なお、係合突起60の先端には鉤形のフック60aが形成され、また、この実施形態では係合突起60は昇降トレイ42と一体に樹脂成形されている。   The document feeder A according to the present invention is characterized in that there is provided a restricting means for preventing the lifting tray 42 from rattling with respect to the paper feed tray 41 when the paper feed tray unit T is rotated upward. It is. As shown in FIG. 4, the restricting means in this embodiment is attached to an engaging protrusion 60 as an engaging member that is formed to protrude from the rear surface on the front end side of the elevating tray 42 and a cover portion 41 b of the paper feed tray 41. And a regulating member 61 as the engaged member. The restricting member 61 engages with the engaging protrusion 60 when the paper feed tray unit T is rotated, and prevents the free end side of the elevating tray 42 from swinging. Note that a hook-shaped hook 60 a is formed at the tip of the engagement protrusion 60, and in this embodiment, the engagement protrusion 60 is resin-molded integrally with the lifting tray 42.

前記規制部材61は、図4及び図5に示すようなブロック状の樹脂成形品であり、カバー部41bの前端の片隅に設けられた凹所62に配置される。この実施形態において、規制部材61は、係合突起60と係合する係合凹部63と、この係合凹部63の後方に位置し規制部材61を係合突起60側に常時付勢する圧縮バネ64が収納される収納部65と、規制部材61を給紙トレイ41のカバー部41aに対して前後方向にスライド支持するスライド部66とを備える。前記係合凹部63は係合突起60が嵌り込む係合溝67と、この係合溝67の上方に位置し嵌り込んだ係合突起60の先端のフック60aと係合する係合上壁68とで構成される。また、前記スライド部66には前後方向に長孔69が形成されており、この長孔69内に配置した2個の段ビス70を給紙トレイ41のカバー部41bに取り付けることで、規制部材61をスライド可能に支持する。さらに、収納部61bに収納される圧縮バネ64は、前端が収納部63の前面壁71に当接し、後端がカバー部41aに設けられたリブ状の突出壁72に当接することで、収納部65内には圧縮された状態で収納される。即ち、図4(a)及び図5(a)に示されるように、給紙トレイユニットTが原稿を繰り出す位置にある時には、規制部材61のスライド部66の前面73を昇降レバー44を収納する外装用カバー74の縦壁面75が押圧することで圧縮バネ64が収納部65内で収縮された状態となり、規制部材61が凹所62内に押し戻された状態で収まる。このとき、係合突起60のフック60aは規制部材61における係合凹部62の係合上壁68とは離れた状態で係合溝67内に嵌り込む。一方、図4(b)及び図5(b)に示されるように、給紙トレイユニットTが上方に回動した時には、規制部材61のスライド部66の前面73が外装用カバー74の縦壁面75による押圧から解除され、圧縮バネ64の弾性力によって規制部材61が前方にスライドしてスライド部66の前面73が凹所62の前端76から突出する。このとき、係合突起60のフック60aは規制部材61における係合凹部62の係合上壁68に係合した状態となる。なお、この実施形態では上記外装用カバー74の縦壁面75を凹所62内に押し戻す規制部材61の押圧部材としているが、本発明の押圧部材はこれに限定されないものである。   The restriction member 61 is a block-shaped resin molded product as shown in FIGS. 4 and 5 and is disposed in a recess 62 provided at one corner of the front end of the cover portion 41b. In this embodiment, the restricting member 61 includes an engaging recess 63 that engages with the engaging protrusion 60, and a compression spring that is positioned behind the engaging recess 63 and constantly biases the restricting member 61 toward the engaging protrusion 60. 64, and a slide portion 66 that slide-supports the regulating member 61 with respect to the cover portion 41a of the paper feed tray 41 in the front-rear direction. The engagement recess 63 has an engagement groove 67 into which the engagement protrusion 60 is fitted, and an engagement upper wall 68 that engages with a hook 60 a at the tip of the engagement protrusion 60 that is positioned and fitted above the engagement groove 67. It consists of. In addition, a long hole 69 is formed in the slide portion 66 in the front-rear direction. By attaching two step screws 70 arranged in the long hole 69 to the cover portion 41 b of the paper feed tray 41, a regulating member 61 is slidably supported. Further, the compression spring 64 stored in the storage portion 61b has a front end that contacts the front wall 71 of the storage portion 63, and a rear end that contacts the rib-shaped protruding wall 72 provided in the cover portion 41a. The unit 65 is stored in a compressed state. That is, as shown in FIGS. 4A and 5A, when the paper feed tray unit T is in a position for feeding out the original, the elevation lever 44 is accommodated in the front surface 73 of the slide portion 66 of the regulating member 61. When the vertical wall surface 75 of the exterior cover 74 is pressed, the compression spring 64 is contracted in the storage portion 65 and the regulating member 61 is accommodated in the state where it is pushed back into the recess 62. At this time, the hook 60 a of the engagement protrusion 60 is fitted into the engagement groove 67 in a state of being separated from the engagement upper wall 68 of the engagement recess 62 in the restriction member 61. On the other hand, as shown in FIGS. 4B and 5B, when the paper feed tray unit T is rotated upward, the front surface 73 of the slide portion 66 of the regulating member 61 is the vertical wall surface of the exterior cover 74. The restriction member 61 is slid forward by the elastic force of the compression spring 64 and the front surface 73 of the slide portion 66 protrudes from the front end 76 of the recess 62. At this time, the hook 60 a of the engagement protrusion 60 is engaged with the engagement upper wall 68 of the engagement recess 62 in the restriction member 61. In this embodiment, the pressing member of the regulating member 61 that pushes the vertical wall surface 75 of the exterior cover 74 back into the recess 62 is used, but the pressing member of the present invention is not limited to this.

次に、上記構成からなる規制手段の作用を図4及び図6に基づいて説明する。図4(a)は、給紙トレイユニットTが原稿を載置する位置にある状態を示したものである。この状態において、規制部材61はスライド部66の前面73が搬送ユニットF側の外装用カバー74の縦壁面75に当接することで、昇降トレイ42の背面に突出形成された係合突起60から離れる方向に押圧される。この押圧作用によって、規制部材61が給紙トレイ41の凹所62内に収まり、係合突起60の先端のフック60aと規制部材61の係合凹部63に設けられた係合上壁68とは係合が解除された状態となる。その結果、昇降トレイ42は昇降レバー44による昇降動作が可能となる。   Next, the effect | action of the control means which consists of the said structure is demonstrated based on FIG.4 and FIG.6. FIG. 4A shows a state where the paper feed tray unit T is in a position for placing a document. In this state, the regulating member 61 moves away from the engaging protrusion 60 formed on the back surface of the elevating tray 42 when the front surface 73 of the slide portion 66 contacts the vertical wall surface 75 of the exterior cover 74 on the transport unit F side. Pressed in the direction. Due to this pressing action, the restricting member 61 is accommodated in the recess 62 of the paper feed tray 41, and the hook 60 a at the tip of the engaging protrusion 60 and the engaging upper wall 68 provided in the engaging recessed portion 63 of the restricting member 61 are The engagement is released. As a result, the lifting tray 42 can be lifted and lowered by the lifting lever 44.

図4(b)は給紙トレイユニットTが前記の載置位置から回動を開始した状態を示したものである。この場合にはスライド部66の前面73が外装用カバー74の縦壁面75から離れることでそれまでの押圧が解除され、圧縮バネ64の弾性力によって規制部材61がスライドし、スライド部66の前面73が凹所62の前端76から突出する。このように規制部材61が係合突起60側に近づくことで、係合突起60の先端フック60aが規制部材61の係合凹部63に設けられた係合上壁68に係合した状態となる。   FIG. 4B shows a state in which the paper feed tray unit T has started to rotate from the placement position. In this case, when the front surface 73 of the slide portion 66 is separated from the vertical wall surface 75 of the exterior cover 74, the previous pressing is released, and the regulating member 61 is slid by the elastic force of the compression spring 64, so that the front surface of the slide portion 66 is 73 protrudes from the front end 76 of the recess 62. Thus, when the regulating member 61 approaches the engaging projection 60 side, the tip hook 60 a of the engaging projection 60 is engaged with the engaging upper wall 68 provided in the engaging recess 63 of the regulating member 61. .

図6は給紙トレイユニットTを先の位置から垂直位置まで回動した時の状態を示すものである。給紙トレイユニットTを垂直位置まで回動させる間及び給紙トレイユニットTをほぼ垂直状態にした後も係合突起60と規制部材61との係合状態が保持される。そのために、昇降トレイ42の自由端である下端側の揺動が拘束されることになり、昇降トレイ42が給紙トレイ41に当って不快音を発するといったことがない。   FIG. 6 shows a state when the paper feed tray unit T is rotated from the previous position to the vertical position. While the paper feed tray unit T is rotated to the vertical position and after the paper feed tray unit T is brought into the substantially vertical state, the engagement state between the engagement protrusion 60 and the regulating member 61 is maintained. For this reason, the swinging of the lower end side, which is the free end of the elevating tray 42, is restricted, so that the elevating tray 42 does not hit the paper feed tray 41 and generate unpleasant noise.

そして再び、給紙トレイユニットTを図6の垂直位置から図4(a)に示すような載置位置に戻すと、規制部材61はスライド部66の前面73が外装用カバー74の縦壁面75に当接し、係合突起60とは離れる方向に押圧されてスライド移動する。これによって、係合突起60と規制部材61との係合が解除され、昇降トレイ42は再び昇降可能な状態となる。   Then, when the sheet feeding tray unit T is returned from the vertical position in FIG. 6 to the placement position as shown in FIG. 4A, the regulating member 61 has the front surface 73 of the slide portion 66 and the vertical wall surface 75 of the exterior cover 74. And is slid by being pushed away from the engagement protrusion 60. As a result, the engagement between the engaging protrusion 60 and the regulating member 61 is released, and the elevating tray 42 is in a state where it can be raised and lowered again.

なお、昇降トレイ42が上昇している時は係合突起60が規制部材61の上方に位置するため、係合突起60のフック60aと規制部材61の係合凹部63が上下方向で位置ズレを生じている。そのために、給紙トレイユニットTを回動させて外装用カバー74の押圧から規制部材61を開放して係合突起60側に突出させたとしても、係合突起60のフック60aが規制部材61の係合凹部63に嵌合しないおそれがある。そのため、このような状態で給紙トレイユニットTを回動すると昇降トレイ42は下端側の動きが拘束されない状態で給紙トレイユニットTと一緒に回動してガタ付きの原因となってしまう。   When the lifting tray 42 is raised, the engaging protrusion 60 is positioned above the restricting member 61. Therefore, the hook 60a of the engaging protrusion 60 and the engaging recess 63 of the restricting member 61 are displaced in the vertical direction. Has occurred. Therefore, even if the sheet feeding tray unit T is rotated to release the restricting member 61 from the pressing of the exterior cover 74 and protrude toward the engaging protrusion 60, the hook 60 a of the engaging protrusion 60 is not restricted by the restricting member 61. There is a possibility that it will not fit into the engaging recess 63. For this reason, when the paper feed tray unit T is rotated in such a state, the lifting tray 42 rotates together with the paper feed tray unit T in a state where the movement of the lower end side is not restrained, which causes a backlash.

本発明では上記のような事態を回避するために、前記規制部材61の係合凹部63を高さ方向、即ち昇降トレイの昇降する方向に複数段設け、昇降トレイ42が上昇している時に給紙トレイユニットTを回動した場合には係合突起60がいずれかの係合凹部63に係合するようにしてもよい。なお、前述したように、この実施形態では昇降トレイ42が上昇している時には、給紙トレイユニットT自体を回動できないように規制している。   In the present invention, in order to avoid the above situation, the engaging recess 63 of the regulating member 61 is provided in a plurality of stages in the height direction, that is, in the direction in which the lifting tray moves up and down, and is supplied when the lifting tray 42 is raised. When the paper tray unit T is rotated, the engagement protrusion 60 may be engaged with one of the engagement recesses 63. As described above, in this embodiment, when the elevating tray 42 is raised, the sheet feeding tray unit T itself is restricted so that it cannot be rotated.

上述した構成によれば、簡易な構造の規制手段でありながら、給紙トレイユニイトTが原稿を繰り出す位置にあるときには、昇降トレイ42の昇降動作を可能とし、給紙トレイユニイトTが回動した状態にあるときには昇降トレイ42の揺動を規制することができる。   According to the above-described configuration, the lifting tray 42 can be moved up and down when the sheet feeding tray unit T is in the position for feeding out the document, while the sheet feeding tray unit T is in a rotated state. In some cases, the swinging of the elevating tray 42 can be restricted.
