Abstract
The invention relates to a processing box for an electronic imaging device, which comprises a powder storage, and the powder storage comprises a cavity which is used to store powdered carbon which can make images developing, a power-delivering roller which is used to deliver the powdered carbon, a powder-taking blade which can adjust the thinness of the powdered carbon and a developing roller, and the developing roller includes an inner layer metal steel shaft and an outer layer conductive rubber; the electronic imaging device can exert a developing bias voltage which is effected by AC and DC on the developing roller into the processing box. Due to adopting the developing roller as the developing device in the jumping developing way, the device can overcome the technique bias that the jumping developing way adopts the magnet roller as the developing device, thereby greatly reducing the preparing precision, difficulty and cost of the processing box of the electronic imaging device.
Description
Technical field
The present invention relates to a kind of handle box that is used for electronic imaging apparatus.
Background technology
Existing electronic imaging apparatus in laser printer, duplicating machine or facsimile recorder, for handle box provides two kinds of different visualization way, and provides two kinds of different development bias voltages and two kinds of different developing apparatuss corresponding to these two kinds of different visualization way.A kind of visualization way is the contact visualization way, is DC voltage corresponding to the development bias voltage of this visualization way, and developing apparatus is that a kind of internal layer is the metallic steel axle, outerly is the developer roll of conductive rubber; Another kind of visualization way is the great-jump-forward visualization way, development bias voltage corresponding to this visualization way is interchange, the coefficient voltage of direct current, because the development bias voltage is interchange, the coefficient voltage of direct current, therefore developing apparatus generally all uses the magnetic roller, also all be to use this magnetic roller in document that retrieves at present and actual the use, and magnetic roller manufacture difficulty is big, production, installation accuracy require high, increase production cost, and compatibility is bad thereby cause manufacturing accuracy height, the difficulty of handle box big, with high costs.
Summary of the invention
The invention provides a kind of handle box of electronic imaging apparatus, cause manufacturing accuracy height, technical matters that difficulty is big, with high costs because of using the magnetic roller as developing apparatus with the handle box that solves existing electronic imaging apparatus.
In order to solve above technical matters, the technical scheme that the present invention takes is:
A kind of handle box that is used for electronic imaging apparatus, described electronic imaging apparatus applies an alternating current and the coefficient development bias voltage of direct current to handle box, comprise a powder storehouse, described powder storehouse comprises cavity, powder feeding roller of carrying carbon dust that is used to store the carbon dust that makes image development and the powder delivery cutter of regulating carbon dust thickness, it is characterized in that: described powder storehouse also comprises developer roll, and described developer roll comprises inner layer metal steel axle and outer conductive rubber; Described development bias voltage is applied on the described developer roll.
Described developer roll also comprises distance piece, and described distance piece is arranged at the two ends of metallic steel axle.
The diameter of described distance piece is than developer roll diameter big 1%-10%.
Described developing roller surface roughness is the 0.8-1.5 micron, and resistivity is the 0.2-0.5 megaohm.
Described powder delivery cutter comprises alloy-steel plate, sheet metal, support, plastic tab; Described sheet metal is selected from a kind of in stainless steel substrates, copper sheet and the deposited film copper sheet.
After having adopted technique scheme, owing to adopt developer roll as developing apparatus in the great-jump-forward visualization way, overcome the great-jump-forward visualization way and generally adopted the technology prejudice of magnetic roller as developing apparatus, thereby greatly reduce handle box manufacturing accuracy, difficulty and the cost of electronic imaging apparatus, the handle box that has solved existing electronic imaging apparatus causes manufacturing accuracy height, technical matters that difficulty is big, with high costs because of using the magnetic roller as developing apparatus.In addition, because more effective extrusion friction takes place for developer roll and powder delivery cutter, make carbon dust charged more even, abundant; At last, because the developer roll surface is an elastomeric material, so skin hardness is less, and wear resistance is better, can cooperate with multiple powder delivery cutter, and is compatible good.

Embodiment
Shown in Fig. 1,5, a kind of handle box 1 that is used for electronic imaging apparatus, electronic imaging apparatus applies an alternating current and the coefficient development bias voltage of direct current to handle box, comprise: powder storehouse 2 and waste powder hopper, powder storehouse 2 comprises cavity, the powder feeding roller 12 of carrying carbon dust that is used to store the carbon dust that makes image development, powder delivery cutter 4 and the developer roll 3 of regulating carbon dust thickness, developer roll 3 comprises inner layer metal steel axle 6, outer conductive rubber 7 and distance piece 5 as shown in Figure 3; The development bias voltage is applied on the developer roll 3, distance piece 5 as shown in Figure 2, be annular plastics spare or the suitable annular element of other intensity, be removable installed in the two ends of metallic steel axle 6, the diameter of distance piece 5 is than developer roll diameter big 1%-10%, so that the conductive rubber 7 on the developer roll 3 does not contact with photosensitive drums, and the maintenance certain distance is a developing gap, the difference of the radius of the exradius of distance piece 5 and developer roll rubber 7 is developing gap, this developing gap is set at 0.2-0.3mm, the color density of print image can be regulated by developing gap, the surfaceness of developer roll 3 is the 0.8-1.5 micron, resistivity is the 0.2-0.5 megaohm, and powder delivery cutter 4 comprises alloy-steel plate 8 as shown in Figure 4, sheet metal 9, support 10 and plastic tab 11; Sheet metal is selected from a kind of in stainless steel substrates, copper sheet and the deposited film copper sheet, and alloy-steel plate 8 is fixed on the powder storehouse 2 by screw, and sheet metal 9, support 10 and plastic tab 11 can be fixed on the alloy-steel plate 8 by adopting modes such as laser electric welding machine.
