Description
本發明與電子成像裝置有關,特別是指一種用於電子成像裝置之碳粉匣。The invention relates to an electronic imaging device, in particular to a toner cartridge for an electronic imaging device.
一般電子成像裝置如影印機或印表機等,皆設有一具有感光鼓的成像匣、以及一碳粉匣與該成像匣組接,該成像匣具有一入粉口,該碳粉匣係用以供應該成像匣於運轉時的碳粉,該碳粉匣具有一殼體、一出粉口設於該殼體且與該入粉口對接、一開關件可移動地設於該殼體、一泡棉設於該開關件、以及一彈性件設於該殼體與該開關件之間,該開關件可相對該殼體於一封閉位置及一開放位置之間移動,當該開關件位於該封閉位置時,該泡棉可輔助該開關件封閉該出粉口,當該開關件位於該開放位置時則未封閉該出粉口,該彈性件施予該開關件一往該封閉位置之作用力,然而,若是該碳粉匣組接於該成像匣時定位不正確,造成該出粉口與該入粉口二者之間的間隙過大,便容易產生碳粉外漏的問題。General electronic imaging devices, such as photocopiers or printers, etc., are all provided with an imaging cartridge with a photosensitive drum, and a toner cartridge is assembled with the imaging cartridge. The imaging cartridge has a powder inlet, and the toner cartridge is used To supply the toner of the imaging cartridge during operation, the toner cartridge has a housing, a powder outlet is arranged on the housing and docked with the powder inlet, a switch is movably arranged on the housing, A foam is arranged on the switch part, and an elastic part is arranged between the casing and the switch part, the switch part can move between a closed position and an open position relative to the casing, when the switch part is in the In the closed position, the foam can assist the switch to close the powder outlet. When the switch is in the open position, the powder outlet is not closed, and the elastic member gives the switch to the closed position. However, if the positioning of the toner cartridge is not correct when it is assembled with the imaging cartridge, the gap between the powder outlet and the powder inlet will be too large, and the problem of toner leakage will easily occur.
此外,該泡棉的厚度及該彈性件亦是另一個容易導致碳粉匣漏粉的潛在因素,若是該泡棉厚度過薄,則無法確實封閉該出粉口;而若該泡棉的厚度過厚,則導致該碳粉匣於組裝時該開關件不易被推動,使該開關件無法移至正確位置;又或者該彈性件可能因彈性疲乏而使該開關件復位不確實,而無法封閉該出粉口,上述狀況不僅造成使用上的浪費,亦會使整個裝置受碳粉的汙染。因此,如何使碳粉匣於組裝時能夠確實的定位,且於組裝前或拆卸後的各階段都不會漏粉,就成了本領域技術人員欲解決的技術問題。In addition, the thickness of the foam and the elastic member are also another potential factor that easily leads to powder leakage from the toner cartridge. If the thickness of the foam is too thin, the powder outlet cannot be closed; and if the thickness of the foam If it is too thick, the switch part will not be easily pushed when the toner cartridge is assembled, so that the switch part cannot be moved to the correct position; or the elastic part may not be reset properly due to elastic fatigue, and cannot be closed The powder outlet, the above-mentioned situation not only causes waste in use, but also makes the whole device polluted by carbon powder. Therefore, how to ensure that the toner cartridge can be accurately positioned during assembly, and how to prevent powder leakage at various stages before assembly or after disassembly, has become a technical problem to be solved by those skilled in the art.
本發明之一目的在於提供一種碳粉匣,與電子成像裝置之成像匣組接後可確實定位;本發明之另一目的在於提供一種碳粉匣,於組裝前或拆卸後都能確實封閉出粉口以避免漏粉。One object of the present invention is to provide a toner cartridge, which can be reliably positioned after being assembled with the imaging cartridge of an electronic imaging device; another object of the present invention is to provide a toner cartridge, which can be reliably sealed out before assembly or after disassembly Powder mouth to avoid powder leakage.
為了達成上述目的,本發明之碳粉匣用來與一電子成像裝置之成像匣組接,該成像匣具有一入粉口、以及一階部位於該入粉口旁,該碳粉匣包含有一殼體,該殼體具有一用來容置碳粉的內部空間、一出粉口連通該內部空間與外界、以及一限位勾設於該出粉口旁,當該碳粉匣與該成像匣組接時,該限位勾勾持於該階部,使該出粉口與該入粉口連通;藉此,該碳粉匣與該成像匣組接後可確實定位,且於組裝前或拆卸後都能確實封閉出粉口以避免漏粉的問題。In order to achieve the above object, the toner cartridge of the present invention is used to assemble with an imaging cartridge of an electronic imaging device, the imaging cartridge has a powder inlet, and a first step is positioned beside the powder inlet, the toner cartridge includes a The casing has an inner space for accommodating carbon powder, a powder outlet connecting the inner space with the outside world, and a limit hook set beside the powder outlet. When the toner cartridge is connected to the imaging When the cartridge is assembled, the limit hook is held on the step, so that the powder outlet and the powder inlet are connected; thereby, the toner cartridge and the imaging cartridge can be positioned accurately after being assembled, and before assembly Or after disassembly, the powder outlet can be sealed to avoid the problem of powder leakage.
以下藉由一較佳實施例配合圖式,詳細說明本發明的技術內容及特徵,如第1圖所示,係本發明一較佳實施例所提供之碳粉匣10設於一成像匣1的立體圖,該成像匣1係設於一電子成像裝置(圖未示)如影印機或印表機等,如第2A、2B圖所示,該成像匣1具有一主體2、一感光鼓3設於該主體2、一下滑片7可滑動地設於該主體2、以及一彈性件(圖未示)設於該主體2與該下滑片7之間,需要說明的是,本發明茲定義沿著平行該感光鼓2之軸向往該成像匣1接近的方向為組入方向D1(如第2A圖所示),反之則為拆卸方向D2(如第1圖所示)。該主體2之末端設有一抵頂部6,該主體2更具有一開口朝上的入粉口4(如圖6-8)、以及一階部5設於該入粉口4旁(如圖2A、圖5),碳粉可經由該入粉口4進到該主體2內部以供該感光鼓3成像,該階部5具有一朝下的階面5a,該下滑片7具有一穿孔8、以及一第一擋止部9位於該穿孔8旁,於本實施例中,該第一擋止部9係形成於該下滑片7的一端,該彈性件施予該下滑片7朝向D2方向的作用力,當該下滑片7受該彈性件作用而朝D2方向移動至一預定位置時可封閉該入粉口4,相對地,當該下滑片7克服該彈性件作用而朝D1方向移動至另一預定位置時該穿孔8與該入粉口4位置對應。
The technical contents and features of the present invention will be described in detail below by using a preferred embodiment in conjunction with the drawings. As shown in Figure 1, the
如第3圖所示,該碳粉匣10包含有一殼體20、一上滑片30、以及一密封件40。
As shown in FIG. 3 , the
請同時參閱第3、6圖,該殼體20具有一用來容置碳粉的內部空間21、一出粉口23連通該內部空間21與外界、一限位勾25設於該出粉口23旁、以及一導引部27設於該出粉口23旁,於本實施例中,該出粉口23位於該殼體20之一底側22,該限位勾25係一體地由該出粉口23旁向下延伸而出且末端具有一朝上的勾面26,該導引部27是一大致沿著水平方向延伸的凸柱。Please refer to Figures 3 and 6 at the same time, the
請同時參閱第4圖,該上滑片30設於該殼體20之底側22且能相對該殼體20於一封閉位置P1及一開放位置P2之間滑動,該上滑片30具有一開口31、一第二擋止部32位於該開口31旁、以及一彈性臂33位於該第二擋止部32後方,該彈性臂33具有一導槽34以及一末端35,該導槽34位於該彈性臂33側邊且可供該殼體20的導引部27伸入,該末端35能由一原始位置P3(如第6圖所示)向下移動至一卡接位置P4(如第8圖所示),該卡接位置P4位於該原始位置P3下方,其中,當該上滑片30位於該封閉位置P1時封閉該出粉口23,當該上滑片30位於該開放位置P2時,該開口31的位置對應於該殼體20之出粉口23,即該上滑片30未封閉該出粉口23。Please refer to Fig. 4 at the same time, the upper
該密封件40設於該上滑片30與該殼體20之間,該密封件40具有一穿孔42且其位置對應於該出粉口23,於本實施例中,該密封件40係一泡棉且固設於該殼體20上,該密封件40受該上滑片30壓抵而有些許變形,以提供較佳的密封效果。The sealing
當該碳粉匣10尚未與該成像匣1組接時,該碳粉匣10之該上滑片30位於該封閉位置P1,如第2、6圖所示,該開口31的位置未對應於該出粉口23,此時,該出粉口23被該上滑片30及該密封件40封閉,該成像匣1之下滑片7亦封閉該入粉口4;該碳粉匣10沿著該組入方向D1移動而與該成像匣1組接的過程中,該限位勾25與該階部5勾持,該勾面26貼抵於該階面5a,如第5、7圖所示,該第二擋止部32推抵於該第一擋止部9並克服該彈性件對於該下滑片7之作用力,使該下滑片7相對該主體2朝該組入方向D1滑動,直到該下滑片7受該主體2之擋止而不再滑動時,該下滑片7之穿孔8恰對應於該入粉口4,且該上滑片30的開口31位置對於於該下滑片7的穿孔8,如第7圖所示。When the
當該碳粉匣10繼續往該組入方向D1移動時,該第二擋止部32受該第一擋止部9的抵頂,使該上滑片30無法相對該下滑片7移動但可相對該殼體20由該封閉位置P1滑動至該開放位置P2,當該上滑片30位於該開放位置P2時,該開口31的位置對應於該出粉口23,使該出粉口23與該入粉口4連通,該殼體20中的碳粉即可進入該成像匣1中,在該上滑片30相對該殼體20滑動的過程中,該導槽34受該導引部27的導引而使該彈性臂33的末端35由該原始位置P3向下移動至該卡接位置P4,令該彈性臂33之末端35與該抵頂部6貼抵,如第1、8圖所示。When the
當該碳粉匣10中的碳粉用盡而使用者欲將該碳粉匣10沿著該拆卸方向D2取出時,由於該彈性臂33的末端35受該抵頂部6的擋止,如第8圖所示,使該上滑片30無法隨該殼體20移動,如此即可使該上滑片30相對該殼體20由該開放位置P2滑動至該封閉位置P1,即使該密封件40因厚度較大或稍有翹曲變形而使摩擦力增加,藉由本發明的結構亦能確實將該上滑片30移送至該封閉位置P1,可避免習知結構中彈性件無法確實將該開關件定位的問題。直到該彈性臂33受到該導引部27的導引而從該卡接位置P4向上回到該原始位置P3時,如第7圖所示,該上滑片30才能隨該殼體20一起脫離該成像匣1,隨後該下滑片7受該彈性件之作用力而復位,並再次封閉該入粉口4,如第6圖所示,即完成整個拆卸碳粉匣的程序。When the toner in the
由於該碳粉匣10之限位勾2 5勾持於該成像匣1之階部5,不僅可使該碳粉匣10準確地定位於該電子成像裝置中,更可使該碳粉匣10與該成像匣1緊密的結合,減小該出粉口23與該入粉口4之間的空隙,確保該碳粉匣10裝設於電子成像裝置時不會漏粉。而在拆卸該碳粉匣10時,該上滑片30可先確實封閉該出粉口23,之後該碳粉匣10才能由該電子成像裝置中取出,如此,不論是該碳粉匣10與該電子成像裝置組裝前、組裝後或是拆卸後,都確保不會有漏粉的問題,進而達成本發明的目的。Since the
需要說明的是,該成像匣1的結構並非本案重點,只要有一入粉口4能與該出粉口23對接、以及一階部5與該限位勾25互相勾持即可,其餘則可有其他變化,例如該下滑片7可省略不設;或者該成像匣1不具有抵頂部6。It should be noted that the structure of the
基於本發明之設計精神,該碳粉匣之結構亦可有其他變化,例如:該上滑片30或該密封件40可以其他可開閉該出粉口23的結構替代;或者導引部27與該導槽34的位置可互換,該彈性臂33與該導引部27亦可有其他設計變化,只要該彈性臂33可受該導引部27的作用而改變位置即可,舉凡此等可輕易思及的結構變化,均應為本發明申請專利範圍所涵蓋。Based on the design spirit of the present invention, the structure of the toner cartridge can also have other changes, for example: the
