Description

The common treatment box

Technical field

The utility model relates to a kind of handle box that is removably installed in image forming apparatus such as Xerox, digital duplicating machine or laser printer.

Background technology

In image forming apparatus, for example Xerox, digital duplicating machine or laser printer etc. are provided with the handle box that is removably installed in it usually.This type of handle box generally constitutes by interconnecting the developing device and the drum assembly that become one structure, and developing device mainly comprises developer storehouse, donor rollers and developer roll etc., and the drum assembly mainly comprises photosensitive drums, charging roller and waste developer storehouse etc.Utilize exposing unit on photosensitive drums, to form electrostatic latent image in the electrofax mode, donor rollers is given developer roll with the developer feeding in the developer storehouse, developer roll further is laid in developer by the electrofax mode and is formed on electrostatic latent image on the photosensitive drums, thereby finishes development.After the developer in the handle box uses up, can fill new developer or the handle box that more renews to it.

There are at present A, B, four kinds of printers of C, D on the market with the different model under a series of, their basic structure and principle of work are substantially the same, just the handle box of each machine machine slipway location that falls is slightly different, thereby also having certain difference in shape with the corresponding handle box of each machine, its difference is mainly reflected on the guiding mechanism.

There is following deficiency in the structure of this series of processes box:

1, the handle box of each model can only be used on the printer of corresponding model, and can not be general on other a series of model printers;

2, this serial printer and handle box are because basic structure and principle of work are basic identical, and the workman causes easily in manufacture process and obscures;

3, because the handle box of each model can not be general, producer need make different production moulds at the difference parts of different model handle box, makes moulding mould development expense excessive, also will increase workloads such as storage, assembling;

4,, must carry out extra technical training, in order to avoid mistake is sold to dealer;

5, the handle box of each model is also very approximate in appearance, easily causes error in judgement visually concerning the user, can make a mistake when buying, and has bought not the handle box to model easily.

The utility model content

The purpose of this utility model is to provide a kind of handle box with universal architecture, can compatible use on the printer of aforementioned multiple model.

For achieving the above object, the utility model has adopted following technical scheme: a kind of common treatment box is provided, comprise developing cell and drum unit, the one side wall in the waste developer storehouse of described drum unit is provided with the guiding mechanism that can cooperate with the slideway in the printer, described guiding mechanism include can be in a chute mobile guide piece of elastic displacement.

Described guiding mechanism also comprises a spring board and a spring that fixedly installs, and this spring is arranged between described spring board and the described mobile guide piece.

The outside surface in described waste developer storehouse is looked for a projection being provided with two near the position of end walls, and these two can be found position and location after looking for a projection can make handle box be placed into image forming apparatus automatically.

Compared with prior art, the utility model common treatment box is because the resilient movement guiding mechanism of its waste developer storehouse one end can adapt to the position and the width variation of the interior machine slideway that falls of the image forming apparatus of multiple model, thereby can be applied to the printer of multiple model, strengthened the versatility of handle box, and simple in structure, convenient and practical.

Embodiment

Referring to Fig. 1 to Fig. 8, common treatment box 1 of the present utility model is formed by connecting by developing cell and drum unit, and its developing cell mainly comprises developer storehouse 2, gear protecting cover 4, developer roll protecting cover 5 and inner members such as unshowned puddle support, donor rollers and developer roll; Its drum unit then mainly comprises waste developer storehouse 3, drum protective cover 6, handle 7, photosensitive drums 8, drum shaft bearing plate 9.The one side wall 13 in waste developer storehouse 3 is provided with a guiding mechanism, this guiding mechanism comprise the chute 31 that is formed on this end wall 13, can the mobile guide piece 32 of chute 31 internal shifts, be fixedly installed on the spring board 33 on the end wall 13 and be arranged on spring board 33 and mobile guide piece 32 between spring 34.Drum shaft bearing plate 9 is just as the support plate of photosensitive drums 8, and its outer face is not provided with orienting lug, the function that has not had handle box 1 to lead in the machine chute 31 that falls.The outside surface in waste developer storehouse 3 is provided with two in the position near end walls and looks for a projection 35, and the inside in waste developer storehouse 3 forms a cavity that enlarges volume.

Fig. 9 and Figure 10 fall into the work synoptic diagram in a kind of printer 10 of series for handle box 1, Xa represents that handle box 1 falls into the direction in the printer 10, Xb represents that handle box 1 is from printer 10 interior directions of taking out, Ya represents that closing of printer 10 cover 12 directions of opening, and Yb represents that closing of printer 10 cover 12 directions of closing.

Its course of work is as follows:

1, along the Ya direction closing of printer 10 tops being covered 12 opens;

2, handle box 1 is put into printer 10 along the Xa direction, mobile guide piece 32 on 3 end walls of waste developer storehouse can be adjusted the position at any time according to the different slideways 11 that the different model machine had in the same series printer at this moment, and fall in the printer 10 with slideway 11 guiding, rouse protective cover 6 simultaneously and be opened;

3, mobile guide piece 32 is to realize adjusting the position at any time because of the different slideway 11 of each machine by the compression or the extension of spring 34 between mobile guide piece 32 and spring board 33 in chute 31;

4, mobile guide piece 32 also can be begun to fight the chip contact-making switch of printer 10 when leading in the slideway 11 of printer 10 and slipping into, and closely pushes down the chip contacts on the handle box 1;

5, shut closing of printer 10 along the Yb direction and cover 12;

6, cover in 12 shutting to close, on the waste developer storehouse 3 two look for a projection 35 can promote automatic capturing position in the printer 10 of handle box 1 in different model after covering 12 light pressure being subjected to closing, be that the driving head of printer 10 can be inserted in being driven in 81 of photosensitive drums 8 one ends on the handle box 1 smoothly, realize that printer 10 can drive photosensitive drums 8 and rotate in handle box 1;

Can drive the developing mechanism in the handle box 1 when 7, photosensitive drums 8 is rotated, thereby realize that handle box 1 develops and printer 10 is printed;

8, use up up to developer, need to change handle box 1, open to close along the Ya direction and cover 12;

9, handle box 1 from printer 10 when the Xb direction is taken out, the mobile guide and withdrawing from slideway 11 of the mobile guide piece 32 on the waste developer storehouse 3, also and then rollback of the chip contact-making switches in the printer 10 simultaneously;

When 10, taking out handle box 1, drum protective cover 6 resets with the photosensitive drums 8 in the protection handle box 1;

11, by the above sequence of steps new handle box 1 of packing in the printer 10.
