Abstract

PURPOSE:To make supply of developer free from unevenness of concentration possible by making uniform agitation of developer. CONSTITUTION:When a toner bottle rotation holder 2 is rotated together with a toner replenishing bottle 1 by driving of a driving gear 7, an eccentric circumference part 2A makes eccentric rotation and pushes a pair of coupling pieces 6, 6 selectively to the left and to the right, and reciprocates agitating blades 4 linearly in the direction of arrow mark (a). The linear movement is secured by sliding of a pin 5a in an oblong hole 3a. The developer in a tank 3 is agitated in the lateral direction by reciprocation of agitating blades 4. Thus, agitation can be made uniformly, and supply of the developer free from unevenness of concentration is made possible.

Description

【発明の詳細な説明】 （技術分野） 本発明は、湿式複写機等に適用される現像液の攪拌装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a developer stirring device applied to wet-type copying machines and the like.

補給しつつ、現像液タンク内の現像液を汲み上げて、感
光体の現像部へ供給する複写機では、現像液タンク内の
現像液を攪拌することが行なわれている。(Prior art) In a copying machine, the developer tank is replenished with toner replenishing solution from a toner supply bottle, and the developer in the developer tank is pumped up and supplied to the developing section of the photoreceptor. The liquid is stirred.

上記攪拌は、現像液タンク内に設けられる攪拌羽根によ

運動によって行なわれるようになっているため、回転遠
心力により現像液が局所的に澱む事態を生じ、現像液が
均一に攪拌されないという問題があった。The above-mentioned stirring is performed by a stirring blade installed in the developer tank, but conventionally, the stirring is performed by the rotational movement of the stirring blade, so that the developer locally stagnates due to rotational centrifugal force. There was a problem in that the developing solution was not uniformly stirred.

（目　　的） 本発明の目的は、現像液の攪拌を均一に行なえるように
した、現像液攪拌装置を提供することにある。(Objective) An object of the present invention is to provide a developer stirring device that can uniformly stir the developer.

対して所定量、偏心している。Two pins 5.5 are attached to the stirring blade 4, and the upper ends 5a of these pins are fitted into the long holes 3a of the tank 3. A pair of engagement pieces 6.6 are also integrally erected on the stirring blade 4, and engage with the circumferential portion 2A provided at the end of the toner bottle rotation holder 2 facing into the tank. It is designed to match. The two circumferential portions are eccentric by a predetermined amount with respect to the rotation center 0 of the toner bottle rotation holder 2, as shown in FIG.

トナーボトル回転ホルダー２には歯車部２Ｂが一体に形

往復運動させる。When the toner bottle rotating holder 2 and the toner supply bottle 1 are rotated together with the driving gear 7, the eccentric circumferential portion 2A shown in FIG. By selectively pushing it leftward and rightward, the stirring blade 4 is linearly reciprocated in the direction of arrow a in FIG.

なお、この直線的な動きは、ピン５ａが長孔３ａを活動
することによって保証される。Note that this linear movement is ensured by the pin 5a activating the elongated hole 3a.

むらのない現像液を供給することが可能となる。The reciprocating movement of the stirring blade 4 causes the developer in the tank 3 to be stirred in the lateral direction. In other words, the conventional rotary agitation type had the disadvantage that the rotating centrifugal force caused local stagnation in the developer and the agitation was not uniform; however, the reciprocating agitation method of the present invention has the disadvantage that this is not the case. These drawbacks are eliminated, stirring can be performed uniformly, and a developer with uniform density can be supplied.

なお、第１図の実施例では、トナー補給ボトルｌも同時

きる。In the embodiment shown in FIG. 1, the toner supply bottle l is also rotated at the same time, so that the liquid in the bottle can be stirred at the same time as the developer in the tank is stirred.

（効　　果） 以上、本発明によれば、従来例のものと比して。(effect) As described above, according to the present invention, compared to the conventional example.

現像液の攪拌を均一に行なうことができるので、濃度む
らのない現像液の供給が可能となる。Since the developer can be stirred uniformly, it is possible to supply the developer without uneven concentration.
