受容側の分離は、トナーの落下が停止している状態で行
なわれる。In electrostatic recording devices that use dry two-component and one-component toners, toner is a consumable agent, and new toner is supplied from the toner box to the developer tank from time to time, and toner remaining on the photosensitive drum after transfer is removed. is received from the cleaning device into a waste toner collection container. In each toner delivery section, toner is passed from the supply side opening to the receiving side by natural fall, as in the conventional Japanese Patent Application Laid-open No. 63-53582, and the toner is transferred to the receiving side from the supply side opening.
Separation on the receiving side is performed while the toner has stopped falling.

入する等の問題もあった。However, with the above-mentioned conventional technology, when the supply side and the receiving side are separated, toner tends to fall from the opening on the supply side and scatter around, and furthermore, the joint may be filled with toner due to incorrect operation. If this occurs, it is impossible to separate the two without causing toner contamination to the outside. Further, when toner is supplied to the developing device, there are problems such as foreign matter getting mixed in through the opening during separation.

機楕を提供することにある。The present invention is intended to solve these problems, and its purpose is to prevent toner from contaminating the outside even when the joint is full of toner.
Toner delivery section and connection valve M that can reliably separate the two
The goal is to provide a machine.

の蓋を兼ねる様にしたことを特徴とする。In the toner delivery section and connection/separation mechanism of the present invention, in the toner delivery section that can be separated into a toner supply side and a toner receiving side, a slide member that opens, closes, and separates the toner path of the connection section is made of two thin slide plates that are in close contact with each other. One side of the slide plate is held on the supply side and the other side is held on the reception side, and when the supply side and the reception side are separated, it also serves as a cover for each opening. Features.

外部へのトナー汚染が発生することがない。According to the above configuration of the present invention, when separating the supply side and the receiving side in the toner delivery section, first, the slide member consisting of two thin slide plates that are in close contact with each other,
It slides to separate the toner filling the toner path of the toner delivery section, and closes the toner path of the toner delivery section. Furthermore, when the supply side and the receiving side are separated, the two thin slide plates are held as lids for the supply side and the receiving side, respectively, so that the inside and outside of the toner path are not directly exposed.
Toner contamination to the outside does not occur.
以下、本発明の実施例を図面によって説明する。 Embodiments of the present invention will be described below with reference to the drawings.
トナーカートリッジから現像器へのトナーの受け渡しを
例に構成を説明し、側断面図にてその作用を説明する。The configuration will be explained using an example of transferring toner from a toner cartridge to a developing device, and its operation will be explained using a side sectional view.

に受け渡される。FIG. 1 is a perspective view when the toner cartridge 3, that is, the toner supply side, and the developing device 4, that is, the toner receiving side are connected and the slide member 10 is pulled out. At this time, the toner path in the connecting portion is open, and the new toner in the toner cartridge 3 is transferred to the developing device 4 by falling naturally.

る。In the figure, reference numeral 20 denotes a lock claw for connection with the toner cartridge 3 rotatably attached to the developing device 4 side, and a spring force is applied to the lock claw so as to hook the toner cartridge convex portion. The slide member 1o consists of a slide plate 11 on the supply side and a slide plate 12 on the receiving side.
When the developing device 4 and the developing device 4 are connected, they come into close contact with each other and slide together as one. Each of the slide plates 11 and 12 is made of a thin sheet metal with a thickness of about 0.8 mm, and both ends thereof are bent into two shapes, and are slidably held on the cartridge side and the developer side, respectively.

先端部は鋭角にするのが望ましい。When separating the supply side and the receiving side, first slide member 1
0 blocks the toner path of the toner delivery section. At this time, as shown in FIG. 2, the slide member 10 slides to separate the toner filling the toner path into the supply side and the receiving side.In order to reduce the resistance when separating the toner, It is desirable that the slide member be as thin as possible, and especially that the tip end be at an acute angle.

付着した面が外部に露出することがない。In fact, at the stage where the supply side and the receiving side are separated, the slide member 10 is in a state where the toner path is completely blocked, as shown in FIG. , and are separated to form a lid that closes the toner delivery path on each supply side and receiving side. Therefore, the toner does not fall or scatter during separation, and in principle, the surface to which the toner is attached is not exposed to the outside.

も適用できるのはもちろんのことである。As for the guide method of the slide plate, in addition to the present embodiment, a structure that utilizes rotation around one common axis during connection may also be considered. It goes without saying that the present invention can be applied not only to toner delivery between a toner cartridge and a developing device, but also to a waste toner collection section and the like.

を分離できるという効果を有する。As described above, according to the present invention, in the toner transfer section that can be separated into the toner supply side and the toner receiving side, the slide member that opens and closes the toner path at the connection section is made up of two thin slide plates that are in close contact with each other. , one side of the slide plate is
The supply side and the other are held on the receiving side, and when the supply side and the receiving side are separated, each serves as a lid, so that when the joint toner path is filled with toner 5. However, it has the effect of separating the filled toner into the supply side and the receiving side, and separating the two without causing toner contamination to the outside.
また原理的にトナー付着面が外部に露出することのない
、トナー受け渡し部の接続脱着機構を達成できるため、
操作者が手を汚すこともない。In addition, it is possible to achieve a connection/detachment mechanism for the toner transfer section that, in principle, does not expose the toner adhesion surface to the outside.
Operators do not have to get their hands dirty.
