200949468 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種由二定位元件、一感光鼓及至少一處理元件組成之處 理匣，其中該感光鼓及處理元件係延伸設置於該二定位元件之間。更詳而 言之，該處理匣係用以經可拆卸之方式裝設於一成像裝置者。 【先前技術】 以下有關本發明背景之敘述係為協助闡明本發明，並非代表申請人承認 以下參照之先前技術於本申請優先權曰期之當時於任何地區為已公佈、已 揭露或屬常識之事實。 家用或商用列印系統之主要功能係將圖文印刷於如紙張等媒體，此等系 統主要包含兩大組件，亦即列印機與處理匣。一般而言，處理匣係組設於 列印機上，且整個列印系統之中所有最需頻繁維修替換的零件幾乎均包含 於其中。 此等零件通常包括墨水或碳粉、滾筒、刮片、螺旋錢、滾輪、傳動齒、 固定件等等。將此等常需替換之零件整合於處理匣中確實有助於提升損壞 零件更換作業之經濟性。 電子照相印刷系統為眾多零件的精密結合體，因此’其處理厘内的元件 必須精確定位，方能確保系統之正常運作。例如，處理匣中的顯影輥即必 須與感光鼓確實分離，以確保其間碳粉的均勻轉印；而處理匣中刮片與滾 筒的設置亦復如此。 通常，處理匣之結構係將各項零件組合後裝入一塑膠外殼中。而後處理 匣接收一旋向驅動力，使其内部需要轉動運作的各項零件，例如滾筒滾 200949468 輪等’產生轉動。為便於零件間旋向驅動力之傳遞，此等轉動運作的零件 * 通常係透過齒輪系相互連結。 對於使用磁性碳粉的非接觸式電子照相處理匣，其感光鼓與顯影輥間的 間隙控制對於列印系統整體效率及列印品質而言至為重要。然此一間隙精 確性極易因外在因素受到影響’包括非圓、非共心或感光鼓或顯影輥任一 者操作表面磨損等等。 為降低此等因素影響間隙精確性’習知處理匣之設計係於感光鼓或顯影 〇 輥之兩端各設有間隔件。因此，當感光鼓與顯影軺i相對靠合時，該間隔件 便可使其間之距離符合設定之標準，從而提供電子照相系統所需之精確顯 影間距。 在習用技術中，上述之靠合係可透過兩種方案家以實現。其一，處理匣 中包含兩部份彼此擺動結合的組件。其中一組件支撐感光鼓，而另一組件 支撐兩端設有轴環狀間隔件之顯影輥❶並透過彈簧將兩部份組件相對靠 合，使感光鼓藉由轴環狀間隔件與顯影輥分隔，從而於二圓周之間界定出 〇 顯影間距。美國專利第6,07〇,〇29號(Canon Kabushiki Kaisha)所揭示者即為 此類系統之範例。 第二種方法係以上下二部份組件構成處理£。下方組制時支律感光鼓 與顯影耗’而以-靠合系統將顯影耗向感光鼓靠攏。顯影親與第一種系統 同樣地在縱長兩端分別設有軸環狀間隔件，藉以將兩者之圓周以間隔關係 設置。 以上兩種以雙組件構紅纽皆具有以下問題：首先此等處理匡組合 之精碟度僅鱗賴彈簧力與軸環狀間隔件。再者，轴環狀間隔件易受系統 5 200949468 中碳粉之污染。此外，上述兩種方法皆須在處理匣中為電子照相零件提供 側向架設系統，尤其是感光鼓與顯影輥，藉以提供側向靠合力，俾使感光 鼓與顯影輥以間距相隔彼此靠合。此等側向支撐系統使得處理匣之長度必 須較感光鼓實際所需的處理寬度更長。所謂處理寬度即為處理匣可輸出之 最大影像寬度。此一寬度取決提供靜電潛像之感光鼓的寬度以及顯影輥用 以實現潛像顯影之碳粉供應寬度。 製造商為求降低原料成本，莫不以縮減列印機體積為目標；而消費者為 了空間與美觀的因素，亦同樣冀求體積輕巧的列印機產品。因此，若能研 發出有效縮減列印機體積之技術，實可造福於社會大眾。 有鑑於此，本發明之目的即在提供一種處理匣，其提供精確控制内部零 件間距之便利方法。 本發明之另一目的在於提供一種處理匣，其所占空間僅稍大於列印作業 實際所需之處理宽度。 【發明内容】 於本說明書中，除非另有說明，否則「包含」、「包括」等語皆應視為非 限疋性之涵義，亦即如同「包括，但不限於」之意。 根據本發明之第-種實魏念，本發明提供_種胁成像裝置之拆卸式 處理匣’該處理匣包含：

Field of the Invention The present invention relates to a processing cartridge composed of two positioning elements, a photosensitive drum and at least one processing element, wherein the photosensitive drum and the processing element are extended to the two positioning positions. Between components. More specifically, the process is used to detachably mount an image forming apparatus. [Prior Art] The following description of the background of the invention is provided to assist in clarifying the invention and is not to be construed as an admission, disclosure or common sense in any place at the time of the priority of the present application. fact. The main function of a home or business printing system is to print graphics on media such as paper. These systems mainly consist of two major components, namely the printer and the processing machine. In general, the processing system is set up on the printer, and almost all of the parts of the entire printing system that require the most frequent replacement are included. Such parts typically include ink or toner, rollers, blades, spiral money, rollers, drive teeth, fasteners, and the like. Integrating these often-replaced parts into the processing shovel does help to improve the economics of damaged part replacement operations. Electrophotographic printing systems are a sophisticated combination of many parts, so the components within their processing must be precisely positioned to ensure proper operation of the system. For example, the developing roller in the processing cartridge must be surely separated from the photosensitive drum to ensure uniform transfer of toner between them, and the setting of the blade and the roller in the processing of the crucible is also the same. Usually, the structure of the crucible is assembled into a plastic casing by combining the parts. The post-processing 匣 receives a rotational driving force so that the various parts that need to be rotated inside, such as the roller roll 200949468, etc., produce a rotation. In order to facilitate the transmission of the rotational driving force between the parts, the parts that are rotated and operated are usually connected to each other through the gear train. For the non-contact electrophotographic process using magnetic toner, the gap control between the photosensitive drum and the developing roller is important for the overall efficiency of the printing system and the print quality. However, the accuracy of this gap is highly susceptible to external factors, including non-circular, non-concentric or photosensitive drum or developing roller wear surface wear and the like. In order to reduce the influence of these factors on the accuracy of the gap, the conventional design is provided with spacers at both ends of the photosensitive drum or the developing roller. Therefore, when the photosensitive drum is in close contact with the developing cartridge i, the spacer can be made to meet the set standard by the distance therebetween, thereby providing the precise development pitch required for the electrophotographic system. In the conventional technology, the above-mentioned relying system can be realized by two schemes. First, the processing 包含 contains two components that are oscillated and coupled to each other. One of the components supports the photosensitive drum, and the other component supports the developing roller 设有 provided with the axially annular spacer at both ends and the two components are relatively opposed by the spring, so that the photosensitive drum is separated from the developing roller by the axial annular spacer Separated to define a 〇 development spacing between the two circumferences. The disclosures of U.S. Patent No. 6,07, and No. 29 (Canon Kabushiki Kaisha) are examples of such systems. The second method consists of the above two components. When the lower part is set, the photoreceptor drum and the developing power consumption are used, and the developing system is used to move the developing power toward the photosensitive drum. The development is similar to the first system. Similarly, axially spaced spacers are provided at both ends of the longitudinal direction, whereby the circumferences of the two are arranged in a spaced relationship. The above two types of two-component red button have the following problems: Firstly, the processing of the combination of the 碟 之 is only the spring force and the axial ring spacer. Furthermore, the axially-spaced spacers are susceptible to contamination by the toner in System 5 200949468. In addition, both of the above methods are required to provide a lateral erection system for the electrophotographic parts in the processing cymbal, in particular, the photosensitive drum and the developing roller, thereby providing a lateral abutting force, so that the photosensitive drum and the developing roller are spaced apart from each other by a distance. . These lateral support systems allow the length of the process to be longer than the actual processing width required for the drum. The processing width is the maximum image width that can be output after processing. This width depends on the width of the photosensitive drum which supplies the electrostatic latent image and the toner supply width which the developing roller uses to develop the latent image. In order to reduce the cost of raw materials, manufacturers do not aim to reduce the size of the printer; consumers are also eager for lightweight printers for space and aesthetics. Therefore, if we can develop a technology that effectively reduces the size of the printer, it can benefit the public. In view of this, it is an object of the present invention to provide a process that provides a convenient method of accurately controlling the spacing of internal parts. Another object of the present invention is to provide a processing cartridge that occupies only slightly more space than is actually required for the printing job. [Invention] In this specification, the words "including" and "including", unless otherwise stated, shall be construed as meaning of non-limiting, that is, as "including, but not limited to". According to the first embodiment of the present invention, the present invention provides a detachable process of the flank imaging device, which comprises: - a plurality of holes for the positioning member; at least - the support member includes a plurality of positioning portions so that Each of the aforementioned positioning elements is disposed in the hole-to-hole towel, and each of the positioning portions is provided with a plurality of holes; wherein the 'at least-branch will stably accommodate the thief-position tree--the hole and the second hole 200949468 hole And at least a portion of a rotating photosensitive drum is received in the hole of the positioning portion in the first hole, and at least a portion of the rotating developing roller is received in the hole of the positioning portion in the second hole, and the hole of the positioning portion is used for Limiting the lateral movement of the rotary photosensitive drum and the rotary developing roller during the processing operation. The support member is preferably a support plate, but may also be a set of connected or unconnected support collars. Each of the positioning elements is made of a hard material. Preferably, the hard material is a stamped metal sheet. The stamped metal sheet not only provides the necessary strength to handle the crucible, but also facilitates the handling of the photosensitive drum, developing pro or other processing elements with the desired degree of itching. In order to reduce the wear caused by the rotation of the photosensitive drum and the developing roller in the support member, the at least one support member is desirably made of a hard but flexible material. Each of the positioning members has a third hole for receiving the other positioning portion of the at least one support member, and wherein at least a portion of a charging roller is received in the hole of the positioning portion in the third hole. Preferably, the third hole is reduced in width by a predetermined distance from the first hole. © The at least one floor member includes an electrical contact for directing electrical power supplied thereto to the rotary photosensitive drum and/or the rotary developing roller and/or the charging roller. The pair of clamping elements form two side walls of at least one of the housing elements. The at least one housing component can be a toner cartridge or a toner recovery unit. Alternatively, the at least one housing element is coupled to the positioning element via screws, glue or other securing means. Preferably, the distance between the pair of positioning elements is at most about 1.15 times the processing width of the processing. More desirably, the distance between the pair of positioning elements is at most about U0 times the processing width of the processing cassette. 7 200949468 In order to reduce/unnecessary cost, the two ends of the photosensitive drum may be provided with a contrasting portion, and the portion of the photosensitive drum that is placed in the "Hay, etc." is the portion. A similar design can be obtained by charging the lighter. According to the present invention, the method of assembling the detachable processing device of the hiding device is provided, and the method comprises: inserting at least the supporting member into the positioning component Each of the at least one hole is provided; at least a portion of the rotating photosensitive drum is inserted into the first hole of the branch member of the first positioning member; at least one of the rotating developing rollers is Partially inserted into the second hole of the support member of the fourth position element; covering the two positioning elements on at least a portion of the rotary photosensitive drum and the rotary developing roller The portion of the rotating photosensitive drum is received in the first hole of the second positioning member (four) of the support member and the portion of the rotary developing light is received in the support inserted in the second positioning member a second hole in the piece; wherein the first hole and the second hole In the operation, the lateral movement of the rotary photosensitive drum and the rotary developing roller is restricted. [Embodiment] The treatment is performed according to the first embodiment of the present invention. The treatment m includes two divisions in the longitudinal direction thereof. The first end of the first positioning element 12 and the second positioning element are disposed under the sigh of the first positioning element 12 and the second positioning element 14 : the photosensitive drum 16 , the developing pro 18 , the friction _ (not shown) Further, the cleaning diagram is not shown, and the charging pro 20.
