〔産業上の利用分野〕
本発明は、電子写真方式のプリンタ及複写機のトナー及
廃トナーのカートリッジに関し、特にトナーと廃トナー
の各部分の体積比を可変にする収容方式に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a toner and waste toner cartridge for electrophotographic printers and copying machines, and particularly to a cartridge for making the volume ratio of each portion of toner and waste toner variable. Regarding the containment method.
従来、この種のトナー・カートリッジはトナー用と廃ト
ナー用とを別々にしていた。Conventionally, this type of toner cartridge has separate toner cartridges and waste toner cartridges.
トナーの消費に伴いトナー・タンク内のトナーが消費さ
れ、同時に廃トナー・タンク内へ廃トナーが回収される
ため、両タンクの空間を確保する大容積のトナー・カー
トリッジを使わざるを得なかった。従って、カートリッ
ジの寸法が大きくなり、装置原価カートリッジの原価を
押上げる欠点があった。As the toner is consumed, the toner in the toner tank is consumed and at the same time the waste toner is collected into the waste toner tank, so it was necessary to use a large-capacity toner cartridge to secure space for both tanks. . Therefore, the size of the cartridge becomes large, which has the drawback of increasing the cost of the device and the cost of the cartridge.
本発明は、トナー・タンクの空間の一部分を廃トナー・
タンクの空間と共用するために、両者間の隔壁を可動式
にする事により、小型でローコストなトナー・カートリ
ッジを提供するものである。The present invention allows a part of the space of the toner tank to be used as waste toner.
By making the partition wall between the two movable so as to share the tank space, a small and low-cost toner cartridge is provided.
すなわち、トナー・カートリッジに於いてトナーを収容

する。That is, in the toner cartridge, the partition wall between the toner accommodating part and the waste toner accommodating part is made movable, and means for feeding and discharging toner into the respective spaces are provided. It is characterized by providing Furthermore, the present invention is characterized in that a movable partition wall is provided in the toner tank or waste toner tank itself of the developing device and cleaner, regardless of whether or not there is a means for feeding and feeding the toner. Further, the present invention is characterized in that the toner box and waste toner box are used in a space enclosed within the photosensitive drum or the photosensitive sheet.
本発明の実施例について図面を参照して説明する。 Embodiments of the present invention will be described with reference to the drawings.
第１図を参照すると、らせんシャフト１が回転方向２に
回転する事により、廃トナー４を送入方向３へ搬送し、
トナー・カートリッジ５の中の廃トナー・タンク部６へ
送入する。一方、らせんシャフト７が回転方向８に回転
する事によりトナー９は送出方向１０へ搬出される。こ
のため、トナー・カートリッジ５内の隔壁１１は、トナ
ー・タンク１２内のトナー９の減少にともない降下方向
１３へ落込んでゆく。そこで、廃トナー４が廃トナー・
タンク部６へ継続的に送入される事が出来る。もちろん
この隔壁１１は柔軟かつ伸縮性を持つ材料より成る隔膜
で代用する事が出来る。Referring to FIG. 1, by rotating the helical shaft 1 in the rotational direction 2, the waste toner 4 is conveyed in the feeding direction 3,
The waste toner is sent to the waste toner tank section 6 in the toner cartridge 5. On the other hand, as the helical shaft 7 rotates in the rotational direction 8, the toner 9 is carried out in the delivery direction 10. Therefore, the partition wall 11 in the toner cartridge 5 falls in the downward direction 13 as the toner 9 in the toner tank 12 decreases. Therefore, the waste toner 4 is
It can be continuously fed into the tank section 6. Of course, this partition wall 11 can be replaced by a partition made of a flexible and stretchable material.
さらに、このトナー・カートリッジ５を現像器あるいは
クリーナーの一部と考えれば、退出部１４あるいは送入
部１５を省略し、代りに現像器あるいはクリーナーを設
ければ良い事は容易に推論出来る。Furthermore, if this toner cartridge 5 is considered as a part of a developing device or a cleaner, it can be easily deduced that the exit section 14 or the feeding section 15 can be omitted and a developing device or a cleaner can be provided instead.
つづいて、第２図を参照すると、本発明のもう１つの実
施例は、感光ドラム２１の中にトナー・カートリッジ２

段２５によりトナーが送出される。感光ドラム２１は、
回転方向２７の方向へ回りながら電極２９で帯電された
後、レーザー光２８で露光し現像器２６で現像されその
後で用紙に転写される。Continuing with reference to FIG. 2, another embodiment of the present invention includes a toner cartridge 2 in the photosensitive drum 21.
2, a partition wall 23 is arranged therein, and the upper side is the waste toner,
The bottom side also serves as a toner cartridge. Of course, the waste toner tank receives waste toner from the cleaner 25 by the inlet means 24, while the developer 26 is also delivered with toner by the outlet means 25. The photosensitive drum 21 is
After being charged by an electrode 29 while rotating in a rotational direction 27, it is exposed to a laser beam 28, developed by a developing device 26, and then transferred to paper.
本発明は、以上説明した様に、トナー・カートリッジ内
に可動隔壁を、設け、トナーの消費に伴い、廃トナーの
スペースが増大する構造を与える事により、トナー・カ
ートリッジの総体的な大きさを減らす事が出来る。As explained above, the present invention reduces the overall size of the toner cartridge by providing a movable partition inside the toner cartridge and providing a structure in which the space for waste toner increases as the toner is consumed. It can be reduced.
