Description
Technical field
The utility model relates to bulging assembly and the handle box of using in a kind of image processing system.
Background technology
Imaging device, or claim electrophotographic imaging forming apparatus, image processing system, be by electrophotographic image forming principle, on recording materials, to form the equipment of image.For example, electrophotographic copier, laser printer, electrophotographic printer (as laser printer and LED printer etc.), facsimile recorder and word processor etc.Imaging device generally includes the handle box being detachably arranged in imaging device main body.
Handle box conventionally can divide and is integrated handle box and split handle box, and wherein split handle box comprises bulging assembly and is detachably installed to the Delevoping cartridge on bulging assembly.
Be illustrated in figure 1 the diagrammatic cross-section of a kind of split handle box in prior art.Handle box 100 comprises bulging assembly 102 and Delevoping cartridge 101.Drum assembly 101 comprises: charger and photosensitive drums 104 etc.Delevoping cartridge 101 comprises: powder storehouse and be contained in the carbon dust in powder storehouse, developer roll 104, powder feeding roller 106, puddle support and powder outlet cutter etc.Puddle support stirs the carbon dust in powder storehouse toward powder feeding roller 106, powder feeding roller 106 is delivered to developer roll 104 by carbon dust, and the carbon dust on developer roll 104 is delivered to photosensitive drums 103 after powder outlet cutter.The carbon dust of photosensitive drums 103 is transferred at transfer roll 107 places that arrange corresponding thereto the paper 110 passing over.Photosensitive drums 103 clockwise rotates, conventionally paper 110 is easily counterclockwise carried toward photosensitive drums 103 after passing over, so very easily there is paperboard, the tip of paper 110 is easily led away the carbon dust of the electrostatic latent image on it when contacting with photosensitive drums 103 in addition, easily forms secret note on the paper after printing.In prior art, by be provided with guide piece 105 on Delevoping cartridge 101, it can prevent that paper 110 is toward counterclockwise carrying, and can make the tip of paper 110 and the mild contact preventing of photosensitive drums 103 make the paper after printing produce secret note.
The handle box of prior art has a problem, because it is split handle box, developer roll is to realize by compeling to push away device with fully contacting of photosensitive drums, namely Delevoping cartridge contacts by compeling to push away to realize with handle box, very high for the accuracy requirement of guide piece like this, it easily directly contacts to develop with photosensitive drums and prints, or and photosensitive drums between excessive not the having of distance prevent that paperboard and printing from having the effect of secret note.
Utility model content
The utility model provides a kind of bulging assembly and handle box, to solve in existing handle box because guide piece precision is controlled the bad shortcoming that paperboard occurs and print secret note.
Above-mentioned technical purpose of the present utility model is to adopt following technical scheme to be achieved:
A kind of bulging assembly, comprise: drum support, photosensitive drums and transfer roll, described photosensitive drums and described transfer roll are arranged on described bulging support, between described photosensitive drums and described transfer roll, form a crush zone, described bulging assembly also includes guide piece, and described guide piece closes on described photosensitive drums and substantially flushes with described crush zone.
Described guide piece is sheet or cylindric, and described guide piece is arranged on the described bulging support that closes on described photosensitive drums two ends.
The number of described guide piece is more than 1.
A handle box, comprises above-mentioned arbitrary described bulging assembly.
Also comprise Delevoping cartridge, described Delevoping cartridge is removably mounted to described bulging assembly, and described Delevoping cartridge comprises developer roll, from installation direction, sees that described guide piece is positioned at described developer roll below and intersects with described photosensitive drums.
With respect to prior art, bulging assembly and handle box that the utility model provides, solved guide piece precision bad control in prior art and can not solve paperboard and print the problem of secret note.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
