Abstract
The utility model relates to a developing case for laser printer, which comprises a carbon powder chamber, an agitating rack, a powder feeding roller, a developing roller, a carbon powder layer thickness adjusting plate, and a photosensitive drum, which are all arranged on the developing case frame. The developing case is provided with positioning grooves at the front outer wall along the direction, along which the developing case inserts into the laser printer. The positioning groove is larger than the corresponding positioning block of the laser printer in width along the Y-axes of the photosensitive drum. An end wall of the positioning groove along the Y-axes of the photosensitive drum leans against the corresponding positioning block of the laser printer. The developing case is adapted to a plurality of types of laser printer having different positioning structures.
Description
Technical field
The utility model relates to the laser printer Delevoping cartridge, and this Delevoping cartridge is removably installed on the laser printer, is used for supply toner, and then the electrostatic latent image that photosensitive drums forms is converted to the visual image that is write down by developers such as carbon dusts.
Background technology
Known laser printer Delevoping cartridge mainly is made of developing cell and image-generating unit.Developing cell mainly comprises toner, puddle support, powder feeding roller, developer roll and carbon dust thickness adjusting plate, and these five parts all are arranged on the developing frame.Image-generating unit mainly comprises photosensitive drums and charging roller, and the two is installed on the cleaning framework.In developing cell, toner provides the storage space and the suitable carbon dust transfer passage of carbon dust; Puddle support evenly distributes the stand-by carbon dust of transporting to developer roll by the rotation of self; The carbon dust thickness adjusting plate provides carbon dust thickness adjusted function to developer roll; Developer roll is adjacent to photosensitive drums, makes carbon dust be adsorbed in electrostatic latent image zone on the photosensitive drums by opposite polarity charge effect.Charging roller periphery in the image-generating unit is pressed against the photosensitive drums periphery tightly, and provides charge function to photosensitive drums, makes the photosensitive drums photosensitive region carry the identical electric charge of charge polarity of polarity and carbon dust absorption.
Under Delevoping cartridge was packed the user mode of laser printer into, photosensitive drum surface was charged equably by charging roller.Laser scanner is launched the laser that contains image information to photosensitive drums, forms corresponding electrostatic latent image at photosensitive drum surface.Carbon dust from developer roll converts the electrostatic latent image on the photosensitive drums to visual image.Along with the rotation of photosensitive drums, replace to transfer roll at the visual image that photosensitive drum surface forms by carbon dust.Through the effect of transfer roll transfer voltage, visual image is transferred on the recording mediums such as paper, with after after warm-up mill and backer roll carry out heating and pressurizing to the visual image on the recording medium, with the visual image full solidification on recording medium.Finish a basic imaging operation like this.
Referring to Fig. 1, existing laser printer Delevoping cartridge 1 inserts on the front end outer wall of laser printer direction X along Delevoping cartridge 1 on its shell, is provided with locating slot 2.This locating slot 2 has several millimeters width along photosensitive drum shaft to y, radially has the degree of depth that is several times as much as its width along photosensitive drums, is used for cooperating with the locating piece 3 of laser printer.During assembling, X aims at locating piece 3 with locating slot 2 along the installation direction, and Delevoping cartridge 1 is inserted in the printer, makes Delevoping cartridge 1 enter the working position.According to different printer models, it can be positioned at Delevoping cartridge 1 along photosensitive drum shaft to varying cross-section on.Thus, the variation of printer model, the position of its locating piece 3 is all different, and then must have the Delevoping cartridge 1 of adaptation to adapt to it.Thus, the laser printer that primary structure is identical, only the difference owing to locating piece just may produce the corresponding with it Delevoping cartridge 1 of many moneys locating slot, thereby has reduced the versatility of Delevoping cartridge, and the user also can meet with the problem of buying inconvenience and cost increase owing to the specificity of Delevoping cartridge.The characteristics of locating piece require to assemble, maintenance job is very meticulous, otherwise the Delevoping cartridge of same model also can not be used for the laser printer corresponding with it because of the position mistake of locating piece, causes unnecessary loss.
The utility model content
The utility model purpose is to provide a kind of and laser printer to have laser printer Delevoping cartridge than the strong fix suitability.
Laser printer Delevoping cartridge of the present utility model, comprise all be arranged at being used on the Delevoping cartridge framework store carbon dust toner, be used to stir and carry carbon dust puddle support, be used for to developer roll carry carbon dust powder feeding roller, be used for carbon dust be converted to photosensitive drums developer roll, be used to regulate developer roll surface carbon powder layer thickness adjustable plate, be used for optical signalling is converted to the photosensitive drums of electrostatic latent image.The Delevoping cartridge framework inserts on the front end outer wall of laser printer direction X along Delevoping cartridge, is provided with locating slot.This locating slot along photosensitive drum shaft to the width of y corresponding locating piece much larger than laser printer.Locating slot along photosensitive drum shaft to the corresponding wall of end wall of y and the corresponding locating piece of laser printer mutually against.
Locating slot along photosensitive drum shaft to the middle body of y can be positioned at Delevoping cartridge along photosensitive drum shaft to the y middle part.
The utility model laser printer Delevoping cartridge utilizes a width to be not less than Delevoping cartridge along half breach of photosensitive drums axial length, replaces existing locating slot, its applicability is extended to the multiple printer of similar profile and function.So, can avoid the user when the buying Delevoping cartridge, to be difficult to buy the worry of specific items.In addition, the Delevoping cartridge after the improvement is the restriction of subject printer model not, and the Delevoping cartridge orientation problem that causes because of printer locating piece reason is solved, and helps raw-material intensive utilization, reduces production costs.
The drawing explanation
Fig. 1 has laser printer Delevoping cartridge structural representation now.
Fig. 2 and 3 the utility model laser printer Delevoping cartridge structural representations illustrate the locating piece matching relationship.
Embodiment
Referring to Fig. 2, the scheme that laser printer Delevoping cartridge 1 of the present utility model and this case background technology are described has identical primary structure, also comprise all be arranged at being used on the Delevoping cartridge framework store carbon dust toner, be used to stir and carry carbon dust puddle support, be used for to developer roll carry carbon dust powder feeding roller, be used for carbon dust be converted to photosensitive drums developer roll, be used to regulate developer roll surface carbon powder layer thickness adjustable plate, be used for optical signalling is converted to the photosensitive drums of electrostatic latent image.On the front end outer wall of the direction X of its insertion laser printer, be provided with locating slot 4 at Delevoping cartridge 1.This locating slot 4 along photosensitive drum shaft to the width of y corresponding locating piece 3 much larger than laser printer.Locating slot 4 along photosensitive drum shaft to the corresponding wall 31 of end wall 41 of y and the corresponding locating piece 3 of laser printer mutually against.Its along photosensitive drum shaft to the middle body of y approximately be positioned at Delevoping cartridge 1 along photosensitive drum shaft to the y middle part.Under the situation of locating piece 3 positions migrations, another end wall of locating slot 4 and the corresponding wall of corresponding locating piece 3 are mutually against (see figure 3) accordingly.
