Abstract

<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of performing an attachment and removal operation of a second image support in a safe and sure manner, while preventing a user's misoperation, in an attachment and removal operation of a second image support. <P>SOLUTION: When a user takes out the second image support from inside a body frame 10, the user first holds knob parts 5 and 6 of the second image support and draws out the image support. When the support is drawn out to some extent, handles 2 and 3 are in the state that they are placed inside a cover 1. (The drawing shows the state that they are taken out from a cover storage part 4.) An interference part 9 faces upward in the drawing. When the handle 2 is kept stored inside the cover, the interference part 9 and the body frame 10 interfere with each other, preventing the second image support from being drawn out. When the user uplifts the handles 2 and 3 for holding them, the interference part 9 comes into the state that it lies getting away from the body, and the second image support can be drawn out from inside the body frame 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、複写機、ファクシミリ、プリンターに用いられる電子写真方式の画像形成装置における第２の像担持体の操作性に関する。   The present invention relates to operability of a second image carrier in an electrophotographic image forming apparatus used for a copying machine, a facsimile machine, and a printer.

従来、複写機等の電子写真方式の画像形成装置において、使用者が第２の像担持体を点検または交換する場合、脱着操作時に問題があった。すなわち、第２の像担持体を本体フレームから取り外す際、使用者が第２の像担持体の保持用の取手を確実に保持した後に取り外すことが必要であるが、この条件が機構上かならずしも保証されておらず、第２の像担持体が脱落する等の不具合が発生するおそれがあった。また、脱落防止用のストッパーが設置されている場合であっても、ストッパーが破損等した場合は、同様の問題が残る。
さらに、保持用の取手が第２の像担持体に格納される方式の場合は、脱着操作時の取手の
位置関係によっては、使用者の誤操作で、やはり第２の像担持体が脱落するおそれが残る等の問題があった。 Conventionally, in an electrophotographic image forming apparatus such as a copying machine, when a user checks or replaces the second image carrier, there has been a problem during the detaching operation. That is, when removing the second image carrier from the main body frame, it is necessary for the user to remove the second image carrier after securely holding the handle for holding the second image carrier, but this condition is not necessarily guaranteed for the mechanism. In this case, there is a possibility that a defect such as the second image carrier dropping off may occur. Even when a stopper for preventing dropout is installed, the same problem remains when the stopper is damaged.
Further, in the case where the holding handle is stored in the second image carrier, the second image carrier may be dropped due to an erroneous operation by the user depending on the positional relationship of the handle at the time of the detachment operation. There were problems such as remaining.

特許文献１には、電子写真方式の画像形成装置において、転写ローラ等を使用者が容易に交換可能とするための軸受部の機構についての開示がある。しかし、本発明の第２の像担持体の脱着方式はカートリッジ方式であり、構成が異なるものである。   Patent Document 1 discloses a mechanism of a bearing portion that enables a user to easily replace a transfer roller or the like in an electrophotographic image forming apparatus. However, the second image carrier attaching / detaching method of the present invention is a cartridge method, and the configuration is different.

第２の像担持体の画像形成装置本体からの脱着操作に際し、使用者の誤操作を防止し、安全確実に第２の像担持体の脱着操作ができる画像形成装置を提供することを課題とする。   It is an object of the present invention to provide an image forming apparatus capable of preventing a user's erroneous operation and safely and reliably detaching / attaching the second image carrier from the main body of the image forming apparatus. .

上記課題を解決するための手段として、本発明は以下の特徴を有している。
請求項１に記載の画像形成装置では、顕像を形成、担持する第１の像担持体と、前記第１の像担持体で形成されたトナー像を担持する第２の像担持体及び記録媒体へ第２の像担持体に形成されたトナー像を記録媒体へ転写させる記録媒体転写装置を有する装置であって、第２の像担持体は本体から脱着可能な構成をなしており、第２の像担持体を脱着する際には操作性を向上するための取手を有し、前記取手は第２の像担持体内部へ収納可能な摺動動作を行う画像形成装置において、前記画像形成装置は、使用者が第２の像担持体を本体から脱着する際には取手を第２の像担持体から取り出して使用者の保持が可能となり、第２の像担持体の取手を第２の像担持体より取り出さずに、第２の像担持体を本体から脱着する際には、取手の一部が本体と干渉して第２の像担持体が脱着不可能な構成であることを特徴とする。
請求項２に記載の画像形成装置では、さらに、前記画像形成装置は、第２の像担持体の取手を複数有し、各々の取手に本体との干渉部を有していることを特徴とする。
請求項３に記載の画像形成装置では、さらに、前記画像形成装置は、第２の像担持体の取手は使用者が保持していない状態では第２の像担持体へ常時収納状態であることを特徴とする。 As means for solving the above problems, the present invention has the following features.
The image forming apparatus according to claim 1, wherein a first image carrier that forms and carries a visible image, a second image carrier that carries a toner image formed by the first image carrier, and recording. An apparatus having a recording medium transfer device for transferring a toner image formed on a second image carrier to a medium to a recording medium, wherein the second image carrier is configured to be detachable from the main body. The image forming apparatus includes a handle for improving operability when the image bearing member is attached to and detached from the second image bearing member, and the handle performs a sliding operation that can be accommodated inside the second image bearing member. When the user removes the second image carrier from the main body, the apparatus can take out the handle from the second image carrier and hold the user, and the second image carrier can be held by the second image carrier. When removing the second image carrier from the main body without removing it from the image carrier, part of the handle is The second image bearing member interferes with the body, characterized in that it is an impossible desorption configuration.

以上説明したように、上記解決するための手段によって、本発明の画像形成装置では、使用者が第２の像担持体の取手を保持しないと脱着不可能であることから、使用者へ確実な保持を行わせることが可能であり、第２の像担持体の脱着時での落下防止等の不具合防止が可能である。
さらに、第２の像担持体の取手を複数有することで、1つの取手が機能不完全状態になっても他の取手にて機能を満足することが可能であるため、使用者の取手保持への信頼性向上が可能である。
さらに、第２の像担持体の取手を常時収納状態が可能な構成にすることで、第２の像担持体を本体へ搭載した後に取手を第２の像担持体内部へ収納するなどの操作を行う必要がないことから操作性の向上を図ることが可能である。 As described above, according to the means for solving the above problem, in the image forming apparatus of the present invention, since the user cannot detach it without holding the handle of the second image carrier, the user can be assured. It is possible to perform holding, and it is possible to prevent problems such as prevention of dropping when the second image carrier is detached.
Furthermore, by having a plurality of handles for the second image carrier, it is possible to satisfy the functions of other handles even if one handle is incompletely functioning. The reliability can be improved.
Further, by adopting a configuration in which the handle of the second image carrier can be stored at all times, an operation such as storing the handle inside the second image carrier after the second image carrier is mounted on the main body. Therefore, it is possible to improve operability.
