Description

シート搬送装置及び画像形成装置Sheet conveying apparatus and image forming apparatus
　本発明は、シート搬送装置及び画像形成装置に関する。 The present invention relates to a sheet conveying apparatus and an image forming apparatus.
　複写機、ファクス、スキャナー、プリンター、又は複合機のような画像形成装置には、シート搬送装置が搭載されている。画像形成装置は、画像読取部と画像形成部とを備える。画像読取部は、原稿に記録された読取画像を読み取る。画像形成部は、画像読取部が読み取った画像に基づいて、コピー用紙のようなシートに画像を形成する。シート搬送装置は、原稿を画像読取部に搬送するために用いられる。 An image forming apparatus such as a copying machine, a fax machine, a scanner, a printer, or a multifunction machine is equipped with a sheet conveying device. The image forming apparatus includes an image reading unit and an image forming unit. The image reading unit reads a read image recorded on a document. The image forming unit forms an image on a sheet such as a copy sheet based on the image read by the image reading unit. The sheet conveying device is used for conveying a document to an image reading unit.
　シート搬送装置は、画像形成装置本体に対して移動可能に取り付けられる。シート搬送装置は、原稿を搬送する搬送部と、搬送部から排出される原稿が積載される積載部とを有する。シート搬送装置と画像形成装置本体とは電線によって電気的に接続されている。電線を介して、シート搬送装置の動作に必要な電力と信号とが画像形成装置本体からシート搬送装置に供給される。 The sheet conveying device is movably attached to the image forming apparatus main body. The sheet conveying apparatus includes a conveying unit that conveys an original and a stacking unit on which an original discharged from the conveying unit is stacked. The sheet conveying device and the image forming apparatus main body are electrically connected by electric wires. Electric power and signals necessary for the operation of the sheet conveying apparatus are supplied from the image forming apparatus main body to the sheet conveying apparatus via the electric wires.
　シート搬送装置が画像形成装置本体に対して移動することで、画像形成装置本体のコンタクトガラスが露出する。シート搬送装置で搬送できない原稿は、コンタクトガラス上に載置される。シート搬送装置で搬送できない原稿は、例えばブック状の原稿である。コンタクトガラス上に載置された原稿に記録された読取画像は、スキャナーによって読み取られる。シート搬送装置には、原稿の移動を規制する突起が設けられている。突起は、シート搬送装置が画像形成装置本体に対して移動する際に、シート搬送装置に積載された原稿が落下することを抑制する。 When the sheet conveying device moves relative to the image forming apparatus main body, the contact glass of the image forming apparatus main body is exposed. A document that cannot be conveyed by the sheet conveying apparatus is placed on the contact glass. The document that cannot be transported by the sheet transport device is, for example, a book-shaped document. A read image recorded on a document placed on the contact glass is read by a scanner. The sheet conveying device is provided with a protrusion that restricts the movement of the document. The protrusions prevent the originals stacked on the sheet conveying apparatus from dropping when the sheet conveying apparatus moves relative to the image forming apparatus main body.
　また、コンタクトガラス上に載置される原稿の厚みによっては、シート搬送装置がコンタクトガラスから離間する場合がある。このため、シート搬送装置と画像形成装置本体とを接続する電線にストレスがかからないように、電線にたわみを持たせている。しかし、電線のたわんだ部分が露出していると、そのたわんだ部分が部屋の壁や他の機器に接触して電線が損傷、劣化する虞がある。そこで、特許文献１に開示の画像形成装置では、画像形成装置本体に凹部が設けられている。凹部の内部には、フックが設けられている。電線がフックに係止され、凹部の内部に収納される。 In addition, depending on the thickness of the document placed on the contact glass, the sheet conveying device may be separated from the contact glass. For this reason, the electric wires are bent so that no stress is applied to the electric wires connecting the sheet conveying apparatus and the image forming apparatus main body. However, if the bent portion of the electric wire is exposed, the bent portion may come into contact with the wall of the room or other equipment, and the electric wire may be damaged or deteriorated. Therefore, in the image forming apparatus disclosed in Patent Document 1, the image forming apparatus main body is provided with a recess. A hook is provided inside the recess. The electric wire is locked by the hook and is stored inside the recess.

　図１Ａに示す画像形成装置１は、例えば、複写機、ファクス、スキャナー、プリンター、又は複合機である。画像形成装置１は、コピー用紙のようなシートに画像を形成する。画像形成装置１は、画像形成装置本体２と、画像形成装置本体２に搭載されたシート搬送装置３とを備える。シート搬送装置３は、読取画像が記録されたシート（以下「原稿」と称する。）を搬送する。 The image forming apparatus 1 shown in FIG. 1A is, for example, a copying machine, a fax machine, a scanner, a printer, or a multifunction machine. The image forming apparatus 1 forms an image on a sheet such as a copy sheet. The image forming apparatus 1 includes an image forming apparatus main body 2 and a sheet conveying apparatus 3 mounted on the image forming apparatus main body 2. The sheet conveying device 3 conveys a sheet on which a read image is recorded (hereinafter referred to as “original”).
　シート搬送装置３は、画像形成装置本体２に移動可能に取り付けられている。シート搬送装置３は、原稿を搬送する搬送部３０と、搬送部３０から排出される原稿が積載される積載部４０とを有する。図１Ｂに示すように、シート搬送装置３は突起５０を有する。突起５０は、シート搬送装置３が移動する際に、積載部４０に積載された原稿の移動を規制する。 The sheet conveying device 3 is movably attached to the image forming apparatus main body 2. The sheet conveying apparatus 3 includes a conveying unit 30 that conveys a document, and a stacking unit 40 on which the document discharged from the conveying unit 30 is stacked. As illustrated in FIG. 1B, the sheet conveying device 3 has a protrusion 50. The protrusion 50 regulates the movement of the document stacked on the stacking unit 40 when the sheet conveying device 3 moves.
　シート搬送装置３は、一対のヒンジ４（一方のみ図示）を介して、画像形成装置本体２に対して回動可能に取り付けられている。シート搬送装置３は、原稿テーブル２０をさらに備える。原稿テーブル２０は、搬送部３０の入口から斜め上方に向けて突出している。原稿テーブル２０には、複数枚の原稿が積載可能である。 The sheet conveying device 3 is rotatably attached to the image forming apparatus main body 2 via a pair of hinges 4 (only one is shown). The sheet conveying device 3 further includes a document table 20. The document table 20 protrudes obliquely upward from the entrance of the conveyance unit 30. A plurality of documents can be stacked on the document table 20.
　搬送部３０は、図示しないが、搬送ローラーや排出ローラー等を有する。搬送部３０は、原稿テーブル２０上に積載された原稿を図１Ａの破線で示す搬送経路Ｐに沿って１枚ずつ搬送する。 The transport unit 30 includes a transport roller, a discharge roller, and the like, although not shown. The conveyance unit 30 conveys the originals stacked on the original table 20 one by one along a conveyance path P indicated by a broken line in FIG. 1A.
　積載部４０は、トレー４１とストッパー４２とを有する。原稿はトレー４１上に排出されて積載される。ストッパー４２は、トレー４１上に排出される原稿を停止させる。ストッパー４２は、トレー４１に対して原稿の排出方向に摺動可能に取り付けられている。したがって、原稿のサイズに合わせたストッパー４２の位置の調節が可能となる。 The loading unit 40 includes a tray 41 and a stopper 42. The document is discharged onto the tray 41 and stacked. The stopper 42 stops the document discharged on the tray 41. The stopper 42 is attached to the tray 41 so as to be slidable in the document discharge direction. Therefore, the position of the stopper 42 can be adjusted according to the size of the document.
　図２は、シート搬送装置３を上方に移動させた状態を示す斜視図である。図２に示されるように、シート搬送装置３は、原稿押さえ７０をさらに備える。原稿押さえ７０は、画像形成装置本体２上に載置された原稿を移動しないように押さえる。 FIG. 2 is a perspective view showing a state where the sheet conveying device 3 is moved upward. As shown in FIG. 2, the sheet conveying device 3 further includes a document presser 70. The document presser 70 presses the document placed on the image forming apparatus main body 2 so as not to move.
　画像形成装置本体２は、画像読取部５と、コンタクトガラス６と、スキャナー（図示せず）と、給紙部（図示せず）と、画像形成部（図示せず）と、定着部（図示せず）と、搬送機構（図示せず）と、操作表示部７とをさらに備える。 The image forming apparatus main body 2 includes an image reading unit 5, a contact glass 6, a scanner (not shown), a paper feeding unit (not shown), an image forming unit (not shown), and a fixing unit (see FIG. (Not shown), a transport mechanism (not shown), and an operation display unit 7 are further provided.
　画像読取部５は、シート搬送装置３によって搬送される原稿の読取画像を読み取る。コンタクトガラス６には、例えば、シート搬送装置３で搬送できない原稿が載置される。シート搬送装置３で搬送できない原稿は、例えばブック状の原稿である。スキャナーは、コンタクトガラス６上に載置された原稿の画像を読み取る。給紙部は、コピー用紙のようなシートを画像形成部に供給する。画像形成部は、画像読取部５又はスキャナーが読み取った画像に基づき、電子写真方式によって、シートにトナー画像を形成する。定着部は、トナー画像をシートに定着させる。搬送機構は、画像が形成されたシートを所定の箇所に排出する。操作表示部７は、表示器７１と、操作ボタン群７２とを含む。表示器７１は液晶パネル等によって構成される。表示器７１は、各種の情報を表示する。操作ボタン群７２は、ユーザーが各種の情報を入力するために用いられる。 The image reading unit 5 reads a read image of a document conveyed by the sheet conveying device 3. For example, a document that cannot be conveyed by the sheet conveying device 3 is placed on the contact glass 6. The document that cannot be transported by the sheet transport device 3 is, for example, a book-shaped document. The scanner reads an image of a document placed on the contact glass 6. The sheet feeding unit supplies a sheet such as a copy sheet to the image forming unit. The image forming unit forms a toner image on the sheet by an electrophotographic method based on the image read by the image reading unit 5 or the scanner.

　図３Ａ及び図３Ｂは、画像形成装置１の上部の側面図である。詳しくは、図３Ａは、シート搬送装置３が画像形成装置本体２の上面に当接した状態を示し、図３Ｂは、シート搬送装置３が画像形成装置本体２の上面から離間した状態を示す。図３Ａに示す状態からシート搬送装置３が一対のヒンジ４（図１Ｂ参照）を支点として、上方に回動すると、積載部４０に積載された原稿Ｍがシート搬送装置３から落下する恐れがある。しかし、本実施形態によれば、図３Ｂに示すように、原稿Ｍが突起５０に当接して原稿Ｍの移動が規制される。よって原稿Ｍのシート搬送装置３からの落下を防止することができる。 3A and 3B are side views of the upper part of the image forming apparatus 1. FIG. Specifically, FIG. 3A shows a state in which the sheet conveying apparatus 3 is in contact with the upper surface of the image forming apparatus main body 2, and FIG. 3B shows a state in which the sheet conveying apparatus 3 is separated from the upper surface of the image forming apparatus main body 2. If the sheet conveying device 3 rotates upward from the state shown in FIG. 3A with the pair of hinges 4 (see FIG. 1B) as fulcrums, the document M stacked on the stacking unit 40 may fall from the sheet conveying device 3. . However, according to the present embodiment, as shown in FIG. 3B, the document M is brought into contact with the protrusion 50 and the movement of the document M is restricted. Therefore, the document M can be prevented from dropping from the sheet conveying device 3.
　図４は、画像形成装置１の平面図である。図５は、図４のＶ－Ｖ線断面図であり、図６は、図４のＶＩ－ＶＩ線断面図である。図５に示すように、突起５０は中空状である。突起５０は、シート搬送装置３と画像形成装置本体２とを電気的に接続する電線Ｃを収納するように形成されている。 FIG. 4 is a plan view of the image forming apparatus 1. 5 is a cross-sectional view taken along the line VV in FIG. 4, and FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. As shown in FIG. 5, the protrusion 50 is hollow. The protrusion 50 is formed so as to accommodate an electric wire C that electrically connects the sheet conveying apparatus 3 and the image forming apparatus main body 2.
　突起５０の内部空間５０ａは、上方に向けて先細りとなるように形成されている。よって、突起５０は、電線Ｃの径方向の移動を規制する。したがって、シート搬送装置３の移動に伴う電線Ｃの位置の変化が抑制されるため、電波ノイズの発生を抑制することができる。また、本実施形態では、突起５０の外観が先細りである。したがって突起５０が小さく見えるため、外観上も好ましい。 The internal space 50a of the protrusion 50 is formed so as to taper upward. Therefore, the protrusion 50 restricts the movement of the electric wire C in the radial direction. Therefore, since the change of the position of the electric wire C accompanying the movement of the sheet conveying apparatus 3 is suppressed, the generation of radio noise can be suppressed. Further, in the present embodiment, the appearance of the protrusion 50 is tapered. Therefore, since the protrusion 50 looks small, it is preferable in terms of appearance.
　図６に示すように、突起５０の内部には電線保持具５１が設けられている。電線保持具５１は電線Ｃを長さ方向に摺動可能に保持する。電線Ｃの一部が上方に円弧状にたわんだ状態で電線Ｃが電線保持具５１に保持されている。電線保持具５１は、シート搬送装置３の移動に伴う電線Ｃの摺動を許容することができる。この構成により、電線Ｃに大きなストレスがかかることを抑制することができる。電線保持具５１を設けることで、電線Ｃの位置の変化が抑制されるため、電波ノイズの発生を抑制することができる。なお、電線保持具５１が無くても電波ノイズが許容範囲の場合には、電線保持具５１を省略してもよい。また、電線保持具５１はシート搬送装置３の筐体に一体的に形成可能である。電線保持具５１がシート搬送装置３に形成された場合、部品点数が増加しないため、シート搬送装置３の構造が複雑化しない。 As shown in FIG. 6, an electric wire holder 51 is provided inside the protrusion 50. The electric wire holder 51 holds the electric wire C so as to be slidable in the length direction. The electric wire C is held by the electric wire holder 51 in a state where a part of the electric wire C is bent upward in an arc shape. The electric wire holder 51 can allow the electric wire C to slide along with the movement of the sheet conveying device 3. With this configuration, it is possible to suppress a great stress from being applied to the electric wire C. Since the change in the position of the electric wire C is suppressed by providing the electric wire holder 51, the generation of radio noise can be suppressed. Note that the electric wire holder 51 may be omitted when the radio noise is within the allowable range even without the electric wire holder 51. Further, the electric wire holder 51 can be formed integrally with the housing of the sheet conveying apparatus 3. When the electric wire holder 51 is formed in the sheet conveying apparatus 3, the number of parts does not increase, and the structure of the sheet conveying apparatus 3 is not complicated.
　シート搬送装置３では、突起５０に電線Ｃのたわんだ部分が収納されるため、電線Ｃのたわんだ部分が部屋の壁や他の機器に接触することがない。したがって、電線Ｃの損傷、劣化を抑制できる。また、シート搬送装置３を画像形成装置本体２に対して移動する際に、電線Ｃがシート搬送装置３と画像形成装置本体２との間に挟み込まれることを抑制できる。 In the sheet conveying apparatus 3, since the bent portion of the electric wire C is accommodated in the protrusion 50, the bent portion of the electric wire C does not contact the wall of the room or other equipment. Therefore, damage and deterioration of the electric wire C can be suppressed. Further, when the sheet conveying apparatus 3 is moved with respect to the image forming apparatus main body 2, it is possible to suppress the electric wire C from being sandwiched between the sheet conveying apparatus 3 and the image forming apparatus main body 2.
　なお、本実施形態では、突起５０は中空となっており、突起５０の内部空間５０ａに電線Ｃが収容される。従って、本実施形態によれば、突起５０に電線Ｃを収納するようにしても、突起は、既存のシート搬送装置にも設けられているが、部品点数が増加することはなく、また、構造を複雑にすることなく、電線Ｃの損傷、劣化を抑制できる。 In this embodiment, the protrusion 50 is hollow, and the electric wire C is accommodated in the internal space 50 a of the protrusion 50. Therefore, according to the present embodiment, even if the electric wire C is accommodated in the protrusion 50, the protrusion is also provided in the existing sheet conveying device, but the number of parts does not increase, and the structure Can be prevented from being damaged and deteriorated.
　図７は、本発明の第２実施形態に係るシート搬送装置１３を備える画像形成装置１１の上部の斜視図である。本実施形態において、第１実施形態と対応する部位には同一の符号を使用し、重複する説明を省略する。本実施形態では、シート搬送装置１３が、画像形成装置本体２に対して昇降可能に取り付けられている。 FIG. 7 is a perspective view of the upper part of the image forming apparatus 11 including the sheet conveying apparatus 13 according to the second embodiment of the present invention. In this embodiment, the same code | symbol is used for the site | part corresponding to 1st Embodiment, and the overlapping description is abbreviate | omitted. In the present embodiment, the sheet conveying device 13 is attached to the image forming apparatus main body 2 so as to be movable up and down.
　図８Ａ及び図８Ｂは、図７に示される画像形成装置１１の上部の側面図である。詳しくは、図８Ａは、シート搬送装置１３が画像形成装置本体２の上面に当接した状態を示し、図８Ｂは、シート搬送装置１３が画像形成装置本体２の上面から離間した状態を示す。図８Ａに示される状態のとき、突起５０の内部に収納された電線Ｃには、図６に示される状態と同様にたわみが生じている。シート搬送装置１３が上昇するにつれて、突起５０の内部に収納された電線Ｃのたわみ量が漸減する。 8A and 8B are side views of the upper portion of the image forming apparatus 11 shown in FIG. Specifically, FIG. 8A shows a state where the sheet conveying device 13 is in contact with the upper surface of the image forming apparatus main body 2, and FIG. 8B shows a state where the sheet conveying device 13 is separated from the upper surface of the image forming apparatus main body 2. In the state shown in FIG. 8A, the electric wire C accommodated in the protrusion 50 is bent similarly to the state shown in FIG. As the sheet conveying device 13 rises, the amount of deflection of the electric wire C housed inside the protrusion 50 gradually decreases.
　図８Ｂに示すように、シート搬送装置１３は、下方に突出する一対のガイド軸６０（一方のみ図示）を有しており、当該ガイド軸６０を介してシート搬送装置１３が画像形成装置本体２に昇降自在に取り付けられている。 As shown in FIG. 8B, the sheet conveying device 13 has a pair of guide shafts 60 (only one is shown) protruding downward, and the sheet conveying device 13 is connected to the image forming apparatus main body 2 via the guide shafts 60. It is attached to the hoist freely.
　図９は、画像形成装置１１の平面図である。図１０は、図９のＸ－Ｘ線断面図であり、図１１は、図９のＸＩ－ＸＩ線断面図である。図１０及び図１１に示すように、図８Ａに示す状態からシート搬送装置１３が上昇することによって、突起５０の内部に収納されている電線Ｃのたわみ量は、減少する。一方、図８Ｂに示す状態からシート搬送装置１３が下降すると、突起５０の内部に収納されている電線Ｃのたわみ量が増加する。 FIG. 9 is a plan view of the image forming apparatus 11. 10 is a cross-sectional view taken along the line XX of FIG. 9, and FIG. 11 is a cross-sectional view taken along the line XI-XI of FIG. As shown in FIGS. 10 and 11, when the sheet conveying device 13 rises from the state shown in FIG. 8A, the deflection amount of the electric wire C housed in the protrusion 50 decreases. On the other hand, when the sheet conveying device 13 is lowered from the state shown in FIG. 8B, the amount of deflection of the electric wire C stored in the protrusion 50 increases.
　次に、図１２及び図１３を参照して、シート搬送装置が昇降する画像形成装置に本発明を適用した場合の有用性について説明する。図１２は、シート搬送装置が回動する画像形成装置のコンタクトガラス６上に原稿Ｍが載置された状態を示す斜視図であり、図１３は、図１２に示される画像形成装置の側面図である。 Next, with reference to FIG. 12 and FIG. 13, usefulness when the present invention is applied to an image forming apparatus in which the sheet conveying apparatus moves up and down will be described. 12 is a perspective view showing a state in which the document M is placed on the contact glass 6 of the image forming apparatus in which the sheet conveying device rotates, and FIG. 13 is a side view of the image forming apparatus shown in FIG. It is.
　図１２及び図１３に示される画像形成装置では、コンタクトガラス６上に載置される原稿Ｍの厚みが大きい程、コンタクトガラス６に対する原稿押さえ７０の傾斜角度αが大きくなる。即ち、シート搬送装置３の原稿押さえ７０が原稿Ｍに当接させられた場合、コンタクトガラス６上に載置される原稿Ｍの厚みが大きい程コンタクトガラス６に対する原稿押さえ７０の傾斜角度αが図１３に示すように大きくなる。その結果、原稿押さえ７０とコンタクトガラス６との距離が大きくなる。このため、スキャナーに外光が入射しやすくなり、コピー用紙のうち、原稿に対応する部分以外の部分が黒く印刷されるため、無駄なトナーが消費されてしまう。 In the image forming apparatus shown in FIGS. 12 and 13, the inclination angle α of the document holder 70 with respect to the contact glass 6 increases as the thickness of the document M placed on the contact glass 6 increases. That is, when the document retainer 70 of the sheet conveying device 3 is brought into contact with the document M, the inclination angle α of the document retainer 70 with respect to the contact glass 6 increases as the thickness of the document M placed on the contact glass 6 increases. As shown in FIG. As a result, the distance between the document holder 70 and the contact glass 6 is increased. For this reason, it becomes easy for external light to enter the scanner, and a portion of the copy paper other than the portion corresponding to the document is printed in black, so that useless toner is consumed.
　一方、シート搬送装置が昇降する画像形成装置では、図８Ｂに示すように、コンタクトガラス６上に載置された原稿Ｍの厚みが大きくても、図１２及び図１３に示される画像形成装置と比べて、原稿押さえ７０とコンタクトガラス６との距離を小さくできる。よって、スキャナーに外光が入射しにくい。したがって、無駄なトナーの消費を抑制することができる。 On the other hand, in the image forming apparatus in which the sheet conveying device moves up and down, as shown in FIG. 8B, even if the thickness of the document M placed on the contact glass 6 is large, the image forming apparatus shown in FIGS. In comparison, the distance between the document holder 70 and the contact glass 6 can be reduced. Therefore, it is difficult for external light to enter the scanner. Therefore, useless toner consumption can be suppressed.
　また、シート搬送装置３が昇降する画像形成装置では、シート搬送装置が回動する画像形成装置と比べて、電線Ｃ（図６参照）の移動距離が大きいため、電線Ｃのたわみ量が大きい。一般的な画像形成装置では、電線が露出しているため、電線のたわみ量が大きくなるほど、電線が部屋の壁や他の機器に接触して損傷、劣化しやすくなる。本発明では、電線Ｃが突起５０内に収納されているため、シート搬送装置が昇降する画像形成装置であっても、電線の損傷、劣化をより確実に抑制することができる。 Further, in the image forming apparatus in which the sheet conveying apparatus 3 is moved up and down, the movement distance of the electric wire C (see FIG. 6) is larger than that of the image forming apparatus in which the sheet conveying apparatus is rotated, so that the deflection amount of the electric wire C is large. In a general image forming apparatus, since the electric wire is exposed, the larger the amount of deflection of the electric wire, the easier it is for the electric wire to come into contact with the wall of the room or other equipment and to be damaged or deteriorated. In the present invention, since the electric wire C is housed in the protrusion 50, damage and deterioration of the electric wire can be more reliably suppressed even in the image forming apparatus in which the sheet conveying device moves up and down.
