Description
【０００１】[0001]
本考案は、画像形成装置の被覆部材を開閉する動作に伴い、駆動部と従動部と の連結・非連結が可能な画像形成装置に関するものである。 The present invention relates to an image forming apparatus capable of connecting / disconnecting a drive unit and a driven unit according to an operation of opening / closing a covering member of the image forming apparatus.
【０００２】[0002]
従来より、画像形成装置内で用紙ジャムが発生した場合、例えば、上下ユニッ トが開閉可能な画像形成装置においては、上ユニットを下ユニットに対して開放 して用紙の搬送路を開放し、ジャム用紙を取り除いていた。また、搬送路を開放 することなく、ジャム用紙を取り除く場合、例えば、定着部付近でジャムが発生 した場合、操作者が定着ローラを回転させてジャム用紙を排出していたが、定着 ローラのギヤが駆動部のギヤと噛合されていると、従動部である定着ローラを回 転させる際に、駆動部も一緒に回転させることになり、駆動部の負荷を受け、ジ ャム処理作業が難行する。そこで、ジャム発生時には、駆動部と従動部とのギヤ の噛合を解除し、駆動部と従動部との連結を解除した後、ジャム処理作業を行う 構成のものがあった。 Conventionally, when a paper jam occurs in the image forming apparatus, for example, in an image forming apparatus in which the upper and lower units can be opened and closed, the upper unit is opened with respect to the lower unit to open the paper conveyance path, and the jam occurs. I was removing the paper. Also, when removing jammed paper without opening the conveyance path, for example, when a jam occurs near the fixing unit, the operator rotated the fixing roller to eject the jammed paper. Is engaged with the gear of the drive unit, the drive unit is also rotated when the fixing roller, which is the driven unit, is rotated, and the load of the drive unit is received, making jam processing difficult. To go. Therefore, there is a configuration in which, when a jam occurs, the gear engagement between the drive unit and the driven unit is released, the connection between the drive unit and the driven unit is released, and then the jam processing operation is performed.
【０００３】 一方、画像形成装置の駆動中は、ギヤ同士の噛合精度が低いと、駆動時にギヤ の歯に無理な力が加わり、ギヤの歯が欠如したりギヤの変形を引き起こす恐れが あるため、ギヤ同士の噛合精度は高精度に組み付けなければならない。On the other hand, while the image forming apparatus is driven, if the meshing accuracy of the gears is low, an unreasonable force may be applied to the gear teeth during driving, which may cause the gear teeth to be missing or deform. , The meshing accuracy of gears must be assembled with high accuracy.
【０００４】 そこで、駆動時には、ギヤ同士を強く噛合しつつ、ジャム発生時には、前記ギ ヤ同士の噛合の解除をスムーズに行う構成にするために、特開平２−１２５１５ ２号公報のように、ギヤ同士の強い噛合を一端緩和させてからギヤの噛合を解除 するような複雑な構成が必要であった。Therefore, in order to have a structure in which the gears are strongly meshed at the time of driving and the meshing of the gears is smoothly released at the time of occurrence of a jam, as disclosed in Japanese Patent Laid-Open No. 2-125152, A complicated structure was required in which the strong meshing between the gears was once eased and then the meshing of the gears was released.
【０００５】[0005]
そこで、ジャム発生時には、駆動部と従動部の連結の解除が簡単に行え、かつ 、画像形成装置の駆動中は、駆動部と従動部が確実にしかも簡単に連結される機 構を得ることを目的とする。 Therefore, in the event of a jam, it is possible to easily release the connection between the drive unit and the driven unit, and to reliably and easily connect the drive unit and the driven unit while the image forming apparatus is being driven. To aim.
【０００６】[0006]
そこで、本考案では、駆動部と、前記駆動部の駆動軸に設けられた第１連結部 材と、前記第１連結部材の回転面に対し垂直な面で当接・離隔し、前記駆動部と 従動部とを連結・非連結する第２連結部材と、前記第２連結部材の当接・離隔す る方向に開閉可能な被覆部材とを備え、前記被覆部材の開動作に伴い、前記第２ 連結部材を前記第１連結部材から離隔させ、駆動部と従動部との連結を解除し、 前記被覆部材の閉動作に伴い、前記第２連結部材を前記第１連結部材に当接させ 、駆動部と従動部とを連結する構成にした。 Therefore, according to the present invention, the drive unit, the first connecting member provided on the drive shaft of the drive unit, and the drive unit are contacted and separated from each other in a plane perpendicular to the rotation surface of the first connecting member. A second connecting member for connecting / disconnecting the driven member and the driven portion; and a covering member that can be opened / closed in a direction of abutting / separating the second connecting member. 2 separating the connecting member from the first connecting member, releasing the connection between the drive unit and the driven unit, and bringing the second connecting member into contact with the first connecting member with the closing operation of the covering member; The drive unit and the driven unit are connected to each other.
【０００７】[0007]
被覆部材の開動作に伴い、第２連結部材を第１連結部材から離隔させ、駆動部 と従動部との連結を解除し、被覆部材の閉動作に伴い、第２連結部材を第１連結 部材に当接させ、駆動部と従動部とを連結する。 With the opening operation of the covering member, the second connecting member is separated from the first connecting member, the connection between the drive unit and the driven unit is released, and the closing operation of the covering member causes the second connecting member to move the first connecting member. The drive part and the driven part are connected to each other.

以下、本考案の画像形成装置について説明する。 The image forming apparatus of the present invention will be described below.
【０００９】 図１は、支点３０を中心としてＸ方向に開閉可能な画像形成装置の被覆部材で ある前側カバー１５を開けた状態を示す。定着・排紙ユニット２０内には、排紙 ローラ２２、定着ローラ２４及びジャム処理用の軸２が内設されており、軸２の 手前側（前側カバー１５側）には、つまみ１が設けられている。前側カバー１５ の内側には、前側カバー１５を閉じた時に、前記つまみ１と当接する位置に対応 して、押し当て板１６が設けられている。その他、画像形成装置内には、現像ユ ニット４０、図示しない感光体、転写部等、公知の画像形成要素が配備されてい る。尚、画像形成装置には、多数枚（例えば、２００枚）の転写紙が積層されて いる給紙カセット５０も装着されており、図示しない給紙ローラにより、給紙カ セット５０内の転写紙が１枚ずつ画像形成装置内に給紙される。FIG. 1 shows a state in which a front cover 15, which is a covering member of an image forming apparatus that can be opened and closed in the X direction around a fulcrum 30, is opened. In the fixing / paper discharging unit 20, a paper discharging roller 22, a fixing roller 24, and a jam processing shaft 2 are provided internally, and a knob 1 is provided on the front side of the shaft 2 (on the front cover 15 side). Has been. A pressing plate 16 is provided inside the front cover 15 at a position corresponding to the knob 1 when the front cover 15 is closed. In addition, in the image forming apparatus, known image forming elements such as a developing unit 40, a photoconductor (not shown), and a transfer unit are provided. The image forming apparatus is also equipped with a paper feed cassette 50 in which a large number (for example, 200) of transfer papers are stacked, and the transfer papers in the paper feed cassette 50 are fed by a paper feed roller not shown. Are fed one by one into the image forming apparatus.
【００１０】 次に、図１における破線Ａの断面図、即ち、定着・排紙ユニット２０の断面図 を図２及び図３に示す。ここで、図２は前側カバー１５を閉じた状態、図３は前 側カバー１５を開けた状態を示す図である。尚、図３中の破線Ｙは前側カバー１ ５を閉じたときの位置を示す。Next, FIG. 2 and FIG. 3 show a cross-sectional view of the broken line A in FIG. 1, that is, a cross-sectional view of the fixing / paper discharging unit 20. Here, FIG. 2 is a view showing the state in which the front cover 15 is closed, and FIG. 3 is a view showing the state in which the front cover 15 is opened. The broken line Y in FIG. 3 indicates the position when the front cover 15 is closed.
【００１１】 図２に示すように、画像形成装置の内部には、定着・排紙ユニット２０に内設 された従動部の定着ローラ２４及び排紙ローラ２２を駆動するための駆動モータ ３が設けられており、駆動モータ３の駆動軸４には、スプリング６の弾性力を受 ける駆動ローラ５が軸方向（矢印Ｂ、Ｂ’方向）に移動可能に設けられている。 前記駆動軸４の先端部には、ワッシャ７が軸設され、駆動ローラ５の矢印Ｂ’方 向（前側カバー１５方向）への移動を規制している。As shown in FIG. 2, inside the image forming apparatus, a drive motor 3 for driving the fixing roller 24 and the paper discharge roller 22 of the driven portion provided in the fixing / paper discharge unit 20 is provided. The drive shaft 4 of the drive motor 3 is provided with a drive roller 5 that receives the elastic force of a spring 6 so as to be movable in the axial direction (arrows B and B'directions). A washer 7 is axially provided at the tip of the drive shaft 4 to regulate the movement of the drive roller 5 in the direction of the arrow B '(direction of the front cover 15).
【００１２】 一方、駆動ローラ５と対向する位置には、ジャム処理用の軸２の一端に軸設さ れた従動ギヤ８が設けられており、駆動ローラ５と従動ギヤ８の各々の突起爪５ ａ、８ａが噛合すると、駆動部と従動部が連結する。従動ギヤ８は、定着ローラ ２４の定着ギヤ２３及び定着ギヤ２３を介して排紙ローラ２２の排紙ギヤ２１と 噛合しており、前記連結により、駆動モータ３の駆動力が、駆動ローラ５を介し て、従動ギヤ８、定着ギヤ２３、排紙ギヤ２１に伝達される構成である。尚、駆 動ローラ５及び従動ギヤ８の各々の爪５ａ、８ａの噛合については、後述する。On the other hand, a driven gear 8 axially provided at one end of the jam clearance shaft 2 is provided at a position facing the drive roller 5, and the projection claws of the drive roller 5 and the driven gear 8 are provided. When 5a and 8a mesh, the drive unit and the driven unit are connected. The driven gear 8 meshes with the fixing gear 23 of the fixing roller 24 and the discharging gear 21 of the discharging roller 22 via the fixing gear 23, and the driving force of the driving motor 3 causes the driving roller 5 to drive the driving roller 5 by the above-mentioned connection. It is configured to be transmitted to the driven gear 8, the fixing gear 23, and the paper discharge gear 21 via the through gear. The engagement of the claws 5a and 8a of the drive roller 5 and the driven gear 8 will be described later.
【００１３】 ジャム処理用の軸２は、定着・排紙ユニット２０に設けられた一対のすべり軸 受９ａ、９ｂを軸通している。前記軸２にはワッシャ１０が軸設され、すべり軸 受９ａとワッシャ１０の間にスプリング１１が挿入されている。図２に示すよう に、前側カバー１５を閉じた状態では、押し当て板１６がつまみ１を押圧し、軸 ２を矢印Ｄ方向（装置本体内方向）に付勢しており、スプリング１１は軸受９ａ とワッシャ１０の間で圧縮される。一方、図３に示すように、前側カバー１５が 開いた状態では、軸受９ａとワッシャ１０の間で圧縮されていたスプリング１１ の弾性力により軸２が矢印Ｄ’方向に飛び出す構成である。The jam clearance shaft 2 passes through a pair of slide bearings 9 a and 9 b provided in the fixing / paper discharging unit 20. A washer 10 is provided on the shaft 2, and a spring 11 is inserted between the slide bearing 9a and the washer 10. As shown in FIG. 2, when the front cover 15 is closed, the pressing plate 16 presses the knob 1 and urges the shaft 2 in the direction of arrow D (inward of the apparatus main body), and the spring 11 causes the bearing to move. Compressed between 9a and washer 10. On the other hand, as shown in FIG. 3, when the front cover 15 is open, the shaft 2 projects in the direction of the arrow D'due to the elastic force of the spring 11 compressed between the bearing 9a and the washer 10.
【００１４】 上述したつまみ１は、軸２に回動可能に取付けられており、さらに、軸２には 従動カラー１２も軸設されており、従動カラー１２とつまみ１の間に、一方向ば ねクラッチ１３が装着してある。ばねクラッチ１３は、つまみ１を矢印Ｃ方向に 回転すると、スプリングに負荷がかかり、スプリングの内径が縮まり、軸２に固 く巻付く。即ち、つまみ１の矢印Ｃ方向の駆動力は、ばねクラッチ１３を介して 軸２に伝達される。逆に、つまみ１を矢印Ｃ方向の逆方向に回転するか、若しく は、軸２自体が矢印Ｃ方向に回転すると、スプリングの内径が開き、スプリング と軸２の間に隙間が発生する。そして、つまみ１、若しくは、軸２が自由に回転 するようになり、駆動伝達が不可能になる。従って、ばねクラッチ１３により、 つまみ１の矢印Ｃ方向の回転の駆動力は従動ギヤ８に伝達されるが、駆動ローラ ５の矢印Ｃ方向の回転は、つまみ１に伝達されない。即ち、駆動ローラ５と従動 ギヤ８の連結時（駆動部と従動部の連結時）、駆動モータ３の駆動力は、駆動ロ ーラ５、従動ギヤ８を介して軸２に伝達されても、ばねクラッチ１３により前記 駆動力は吸収されてしまい、つまみ１を回転させず押し当て板１６を削る恐れは ない。尚、ばねクラッチ１３を設ける代わりに、前側カバー１５の押し当て板１ ６にベアリングを填め込む構成でも、同様の効果を得られる。The knob 1 described above is rotatably attached to the shaft 2, and a driven collar 12 is also axially installed on the shaft 2, and between the driven collar 12 and the knob 1 is a unidirectional blade. The clutch 13 is attached. When the knob 1 is rotated in the direction of arrow C, the spring clutch 13 applies a load to the spring, the inner diameter of the spring is reduced, and the spring clutch 13 is tightly wound around the shaft 2. That is, the driving force of the knob 1 in the direction of arrow C is transmitted to the shaft 2 via the spring clutch 13. On the contrary, when the knob 1 is rotated in the direction opposite to the arrow C direction, or when the shaft 2 itself is rotated in the arrow C direction, the inner diameter of the spring is opened and a gap is generated between the spring and the shaft 2. Then, the knob 1 or the shaft 2 is allowed to rotate freely, and drive transmission becomes impossible. Therefore, the driving force of the rotation of the knob 1 in the direction of arrow C is transmitted to the driven gear 8 by the spring clutch 13, but the rotation of the driving roller 5 in the direction of arrow C is not transmitted to the knob 1. That is, when the drive roller 5 and the driven gear 8 are connected (when the drive unit and the driven unit are connected), the driving force of the drive motor 3 is transmitted to the shaft 2 via the drive roller 5 and the driven gear 8. The spring clutch 13 absorbs the driving force, and there is no fear of scraping the pressing plate 16 without rotating the knob 1. In addition, instead of providing the spring clutch 13, the same effect can be obtained even if the bearing is fitted in the pressing plate 16 of the front cover 15.
【００１５】 次に、駆動ローラ５、従動ギヤ８の各々の爪５ａ、８ａについて説明する。 図４、図５に示すように、駆動ローラ５、従動ギヤ８の突起状の爪５ａ、８ａ は同形状であり、駆動時は、爪５ａ、８ａの各々の面５Ｍ、８Ｍ同士が当接し、 駆動の回転に伴って、駆動力を伝達する構成である。また、爪５ａ、８ａには、 斜面５Ｓ、８Ｓが設けられており、斜面５Ｓ、８Ｓ同士が当接した時はすべり合 う方向に力が作用する形状である。Next, the claws 5a and 8a of the drive roller 5 and the driven gear 8 will be described. As shown in FIGS. 4 and 5, the drive roller 5 and the protruding claws 5a and 8a of the driven gear 8 have the same shape, and when driving, the respective faces 5M and 8M of the claws 5a and 8a contact each other. The drive force is transmitted as the drive rotates. Further, the claws 5a and 8a are provided with slopes 5S and 8S, and when the slopes 5S and 8S come into contact with each other, a force acts in a sliding direction.
【００１６】 次に、上記のように構成された画像形成装置の動作を説明する。 まず、定着・排紙ユニット２０内でジャムが発生した場合、前側カバー１５を 図１に示すようにＸ方向に開ける。すると、図３に示すように、すべり軸受９ａ とワッシャ１０との間で圧縮されたスプリング１１の弾性力により、軸２が矢印 Ｄ’方向（前側カバー１５側）に移動する。この時、駆動ローラ５と従動ギヤ８ の爪５ａ、８ａの噛合が解除され、駆動ローラ５と従動ギヤ８が離隔する。即ち 、駆動ローラ５と従動ギヤ８との連結が解除される。しかし、前記連結が解除さ れても、従動部側の従動ギヤ８、定着ギヤ２３、排紙ギヤ２１は噛合されており 、つまみ１を矢印Ｃ方向に回転することにより、ばねクラッチ１３を介して軸２ が回転し、従動ギヤ８、定着ギヤ２３、排紙ギヤ２１の各々に駆動伝達がなされ 、定着ローラ２４、排紙ローラ２２を自在に回転させることができる。即ち、前 側カバー１５を開ける動作に伴い、駆動部と従動部の連結が解除され、つまみ１ を回転することにより、定着ローラや排紙ローラの従動部を自在に駆動させるこ とができる。Next, the operation of the image forming apparatus configured as described above will be described. First, when a jam occurs in the fixing / paper discharge unit 20, the front cover 15 is opened in the X direction as shown in FIG. Then, as shown in FIG. 3, the shaft 2 moves in the direction of arrow D '(on the side of the front cover 15) by the elastic force of the spring 11 compressed between the slide bearing 9a and the washer 10. At this time, the engagement between the drive roller 5 and the claws 5a, 8a of the driven gear 8 is released, and the drive roller 5 and the driven gear 8 are separated from each other. That is, the connection between the drive roller 5 and the driven gear 8 is released. However, even if the connection is released, the driven gear 8, the fixing gear 23, and the paper discharge gear 21 on the driven portion side are meshed with each other, and by rotating the knob 1 in the direction of arrow C, the spring clutch 13 is interposed. The shaft 2 rotates, and drive is transmitted to each of the driven gear 8, the fixing gear 23, and the paper discharge gear 21, and the fixing roller 24 and the paper discharge roller 22 can be freely rotated. That is, when the front cover 15 is opened, the driving part and the driven part are disconnected from each other, and the knob 1 is rotated to freely drive the driven parts of the fixing roller and the paper discharge roller.
【００１７】 一方、前側カバー１５を閉じる動作に伴い、図２に示すように、押し当て板１ ６がつまみ１を矢印Ｄ方向に押圧し、軸２を矢印Ｄ方向に移動する。すると、各 々の爪５ａ、８ａが衝突し、スプリング６が矢印Ｂ方向に圧縮され、駆動ローラ ５が矢印Ｂ方向に移動する。この時、爪の斜面５Ｓ、８Ｓ同士は当接し、衝突力 を回避する方向に力が作用している。そして、駆動モータ３が回転すると、駆動 ローラ５が回転し、爪の斜面５Ｓ、８Ｓですべりあい、爪同士の衝突力を回避す る方向に力が作用し、爪の衝突が解除される。そして、スプリング６の弾性力に より爪の面５Ｍ、８Ｍ同士が当接し、駆動力を伝達するように噛合する構成であ る。即ち、前側カバー１５を閉じる動作に伴い、駆動部と従動部が連結される。On the other hand, as the front cover 15 is closed, as shown in FIG. 2, the pressing plate 16 pushes the knob 1 in the direction of arrow D and moves the shaft 2 in the direction of arrow D. Then, the claws 5a and 8a collide with each other, the spring 6 is compressed in the arrow B direction, and the drive roller 5 moves in the arrow B direction. At this time, the inclined surfaces 5S and 8S of the claws are in contact with each other, and the force acts in the direction to avoid the collision force. Then, when the drive motor 3 rotates, the drive roller 5 rotates and slides on the slopes 5S and 8S of the claws, a force acts in a direction to avoid the collision force between the claws, and the claw collision is released. The elastic force of the spring 6 causes the claw surfaces 5M and 8M to come into contact with each other and mesh with each other so as to transmit the driving force. That is, with the operation of closing the front cover 15, the drive unit and the driven unit are connected.
【００１８】[0018]
上記の構成にしたことにより、被覆部材の開動作に伴って、駆動部と従動部の 連結が解除され、つまみを回転するだけで定着ローラや排紙ローラ等の従動部を 自在に駆動させることができるため、ジャム処理操作が簡単である。また、被覆 部材の閉動作に伴い、駆動部と従動部の連結がなされるため、前記連結動作が簡 単である。 With the above configuration, the driving unit and the driven unit are disconnected from each other when the covering member is opened, and the driven units such as the fixing roller and the discharge roller can be freely driven only by rotating the knob. Therefore, the jam handling operation is easy. Further, since the driving part and the driven part are connected together with the closing operation of the covering member, the connecting operation is simple.
