Abstract
An imaging device used in a laser printer comprises a developer storage room used for storing of the developer, and an agitation stand used to mix the developer stored in the developer storage room; wherein, the side walls on transversal ends of the storage room are translucidus walls which allow the passing through of detection light form the laser printer. The imaging device can accurately detect the residual amount of developer in the developer storage room, and is applicable for laser printer with same exterior and functions.
Description
Technical field
The utility model relates to the laser printer developing apparatus, and this developing apparatus is removably installed on the laser printer.
Background technology
Usually, common developing apparatus comprises the developer apotheca of depositing developer and the developing room that developer roll is set.Opening is formed on the zone between developer apotheca and the developing room, so that developer is input to developing room by this opening.The structure of common developing apparatus can detect the surplus of developer in the developer apotheca, in case developer level drops to the predetermined value of a lower limit, then notifies the user to change developing apparatus.
There is the whole bag of tricks to be used for detecting carbon dust amount residual in Delevoping cartridge now, wherein the patent No. is the Chinese patent of CN00106749.4, disclosed a kind of detection method that belongs to the light beam projection type, that is: a kind of developing apparatus, it has the developer apotheca, be provided with puddle support in the developer apotheca, the developer apotheca have a pair of can be by the light inlet window of light.If there is not developer between the light inlet window, the detection light that sends from laser printer directly passes through this light inlet window, and produces this developing apparatus is changed in indication with new developing apparatus signal; If have developer between two light inlet windows, then detect light and can not pass two light inlet windows.But because the transmittance of transparency window is than higher; when the developer exhaustion in the developing apparatus when a certain amount of; the detection light of laser printer is easier to pass this transparency window; lack and the rub-out signal of changing developing apparatus thereby produce developer, in fact in developing apparatus, also have the developer of 60g usually.Thereby increased user's printing cost, caused the waste of developer, contaminated environment.Secondly install light inlet window at the two ends of developer apotheca, can make the complex structure of developing apparatus, increase manufacturing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of developing apparatus, and this developing apparatus can accurately detect the surplus of developer in the developer apotheca, and this developing apparatus can be applicable to the laser printer with similar profile and function.
The purpose of this utility model realizes by following proposal.
Laser printer developing device of the present utility model comprises: a developer apotheca is used for storage of developer; One is arranged on the puddle support in the developer apotheca, is used to stir developer; Wherein, the sidewall of described developer apotheca lateral ends is transmissive wall, when the developer in the developer apotheca ran out of soon, the detection luminous energy of laser printer passed this transmissive wall, and produced this developing apparatus is changed in indication with new developing apparatus signal.
More concrete is, the transmissive wall of developer apotheca lateral ends, equal light-permeable, its applicability can be extended to the multiple printer of similar profile and function, so, can avoid the user when buying developing apparatus, to be difficult to buy the worry of specific items, help raw-material intensive utilization, reduce production costs.

Embodiment
Referring to Fig. 1, the utility model developing apparatus 1 is made up of cover 2 and housing 3.Referring to Fig. 3, housing 3 comprises developer apotheca 31 and the developing room 32 that is used for storage of developer.One puddle support 313 is arranged in the developer apotheca 31, is used to stir developer.One developer supply roller 321 and developer roll 322 can be rotatably set in the developing room 32.Between developer apotheca 31 and developing room 32, be provided with an open C, so that the developer in the developer apotheca 31 is input in the developing room 32 by open C.
Referring to Fig. 4 and Fig. 5, developer apotheca 31 lateral ends sidewalls are transmissive wall 311 and 312.Laser printer light emitting devices and light receiving device are positioned at the opposite side of the developing apparatus corresponding with transmissive wall 311 and transmissive wall 312.When being reduced to, the developer highest level face consumption in the developer apotheca 31 just allows when the detection light that light emitting devices sends passes through, detect light earlier by transmissive wall 311, enter in the developer apotheca 31, enter detection light in the developer apotheca 31 again from transmissive wall 312, arrive the light receiving device of laser printer, thereby produce this developing apparatus is changed in indication with new developing apparatus signal.
Developer plane in developer apotheca 31 is depleted to when just allowing detection light to pass through, amount of residual developer in the developer apotheca 31 is approximately 60g, if this moment, printer is directly pointed out needs to change developing apparatus, the user can think that the developer in the developer apotheca 31 uses up by mistake, and change developing apparatus 1, can cause the waste of developer like this, contaminated environment.Transmissive wall 311 of the present utility model and 312 is injection molded by the transparent black race of transparent ABS resin blending, wherein decay plays to the detection light of laser printer in black race, so can prolong the time that light arrives the light receiving device of detecting, postpone producing and indicate the signal of changing this developing apparatus with new developing apparatus, thereby improve the utilization factor of developer.
