Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は電子写真装置の用紙スキュー補正装置に関する。 The present invention relates to a paper skew correction device for an electrophotographic apparatus.

【0002】[0002]

【従来の技術】[Prior art]

従来より複写機やレーザプリンタなどの電子写真装置においては、感光体に形 成されたトナー像を印刷用紙へ転写するに先立ち、印刷用紙の走行姿勢を補正し 、正しい向きで印刷用紙を転写位置へ送り込むようにしている。 In the past, in electrophotographic devices such as copiers and laser printers, the transfer position of the printing paper is adjusted in the correct direction by correcting the running posture of the printing paper before transferring the toner image formed on the photoconductor to the printing paper. I am sending it to.

【0003】 例えば、図4に示すように用紙搬送ベルト1上へ送り込まれた印刷用紙4は、 搬送ロール10へ送り込まれる前に一旦、ストッパ12に当接し、印刷用紙4の 先端位置が用紙搬送方向に対しほぼ直交する状態となるように補正された後、搬 送ロール10側へ搬送している。For example, as shown in FIG. 4, the printing paper 4 sent onto the paper carrying belt 1 once comes into contact with the stopper 12 before being sent to the carrying roll 10 so that the leading end position of the printing paper 4 is carried. After being corrected so as to be substantially orthogonal to the direction, it is conveyed to the conveying roll 10 side.

【0004】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来技術においては図4に示すようにストッパ12がベルト11側面部に一体 に設けられていたので、ストッパ12が印刷用紙4の当接によって摩耗した場合 、ベルト11全体を交換しなければならず保守性に欠けていた。 In the prior art, the stopper 12 is integrally provided on the side surface of the belt 11 as shown in FIG. 4, so that when the stopper 12 is worn by the contact of the printing paper 4, the entire belt 11 must be replaced. It lacked maintainability.

【0005】 本考案の目的は、ストッパ部材の交換を容易に行えるようにし、保守性に優れ た用紙スキュー補正装置を提供することにある。An object of the present invention is to provide a paper skew correction device that facilitates replacement of a stopper member and has excellent maintainability.

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的は、ベルト部材側面部にストッパ部材装着用の突起部を設けるととも に、ストッパ部材を前記突起部に対し着脱自在に設け、少なくとも印刷用紙が当 接する側のストッパ部材側面部には、ベルト部材とストッパ部材との係合部への 印刷用紙の侵入を防止する弾性片を設けることによって達成される。 The above object is to provide a protrusion for mounting a stopper member on the side surface of the belt member, and to dispose the stopper member detachably with respect to the protrusion, and at least on the side surface of the stopper member on the side where the printing paper contacts. This is achieved by providing an elastic piece that prevents the printing paper from entering the engaging portion between the belt member and the stopper member.

【0007】[0007]

【作用】[Action]

本考案によれば、保守性に優れた用紙スキュー補正装置を提供することが可能 となる。 According to the present invention, it is possible to provide a paper skew correction device having excellent maintainability.

【実施例】【Example】

以下、本考案の実施例を図面を用いて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

【0009】 図1において用紙搬送ベルト1は、駆動ローラ2および従動ローラ3に架け渡 されており、用紙搬送ベルト1上の印刷用紙4を矢印a方向へ搬送するように設 けられている。In FIG. 1, the paper transport belt 1 is stretched over a drive roller 2 and a driven roller 3, and is configured to transport the print paper 4 on the paper transport belt 1 in the direction of arrow a.

【0010】 用紙搬送ベルト1の下流側上方部に設けられた用紙スキュー補正装置5は、ベ ルト部材6と、ベルト部材6を支持する駆動ローラ7および従動ローラ8と、ベ ルト部材6に対し着脱自在に設けられたストッパ部材9から構成されている。The sheet skew correction device 5 provided on the downstream upper side of the sheet conveying belt 1 has a belt member 6, a driving roller 7 and a driven roller 8 that support the belt member 6, and a belt member 6. The stopper member 9 is detachably provided.

【0011】 用紙スキュー補正装置5は、用紙搬送ベルト1上面で搬送されてきた印刷用紙 4の先端を一旦ストッパ部材9に当接させてスキュー補正を行った後、ベルト部 材6を矢印b方向へ駆動させることによりストッパ部材9を用紙搬送路中から一 時的に取り除き、搬送ロール機構10側へ印刷用紙4を送り出すように制御され ている。The sheet skew correction device 5 temporarily skews the front end of the printing sheet 4 conveyed on the upper surface of the sheet conveying belt 1 to the stopper member 9 to correct the skew, and then moves the belt member 6 in the direction of arrow b. It is controlled so that the stopper member 9 is temporarily removed from the sheet conveying path by driving the sheet to the conveying roll mechanism 10 side.

【0012】 次にベルト部材6とストッパ部材9の関係を図2を用いて説明する。Next, the relationship between the belt member 6 and the stopper member 9 will be described with reference to FIG.

【0013】 ベルト部材6側面部には突起部6aが形成されており、突起部6a側面には後 に述べるストッパ部材9の位置決めとして機能する凹部6bが設けられている。A protrusion 6 a is formed on the side surface of the belt member 6, and a recess 6 b that functions as positioning of a stopper member 9 described later is provided on the side surface of the protrusion 6 a.

【0014】 一方、ストッパ部材9は、ベルト部材6に形成した突起部6aを挟み込むよう なU字形状に形成されており、ストッパ部材9内壁面には、突起部6aに設けた 凹部6bに係合する凸部9aが設けられている。On the other hand, the stopper member 9 is formed in a U shape so as to sandwich the protrusion 6 a formed on the belt member 6, and the inner wall surface of the stopper member 9 engages with the recess 6 b provided on the protrusion 6 a. A matching convex portion 9a is provided.

【0015】 また、ストッパ部材9の印刷用紙が当接する側の側面部には、厚さ0.2mm以 下程度に形成された弾性変形可能な弾性片9bが設けられており、図3に示すよ うにストッパ部材9をベルト部材6に装着した際に両者間に生じる隙間dへの印 刷用紙4の侵入を弾性片9bにより防ぐようにしている。Further, an elastically deformable elastic piece 9b having a thickness of about 0.2 mm or less is provided on the side surface of the stopper member 9 on the side where the printing paper comes into contact, as shown in FIG. Thus, when the stopper member 9 is attached to the belt member 6, the elastic piece 9b prevents the printing paper 4 from entering the gap d generated between the stopper member 9 and the belt member 6.

【0016】[0016]

【考案の効果】[Effect of device]

本考案によれば、ベルト部材に対しストッパ部材を着脱自在に設けたので、ス トッパ部材の交換を容易に行え、保守性に優れた用紙スキュー補正装置を提供す ることができる。 According to the present invention, since the stopper member is detachably attached to the belt member, it is possible to easily replace the stopper member and to provide a paper skew correction device having excellent maintainability.

【0017】 また、印刷用紙が当接する側のストッパ部材側面部には、ベルト部材とストッ パ部材との係合部への印刷用紙の侵入を防止する弾性片を設けたので、ストッパ 部材とベルト部材とを分割構造にしたことによる障害等をまねくことなく、安定 した印刷用紙の搬送を実現することができる。Since the elastic piece for preventing the printing paper from entering the engaging portion between the belt member and the stopper member is provided on the side surface portion of the stopper member on the side where the printing paper comes into contact, the stopper member and the belt. It is possible to realize stable conveyance of printing paper without causing obstacles and the like due to the divided structure of the members.
