Description
Technical field
The utility model relates to the laser printer developer reservoir, particularly disposing developer in it stirs and delivery mechanism, be used for splendid attire scheduled volume developer, and laying in developer in it is delivered to developer roll by the supply opening that is provided with on its wall developer reservoir.
Background technology
Electrophotographic image forming, laser printer for example, its use value shows as by containing the laser beam that predetermined information is arranged has predetermined potential with the scan mode irradiation photosensitive drums, form electrostatic latent image at photosensitive drum surface, and then the developer of this electrostatic latent image with predetermined carbon dust and so on developed, be transferred to the carbon dust image that is about to obtain on the recording medium such as paper through developing, afterwards again the image fixing of transfer printing acquisition, become the visual image that naked eyes can be observed, realize the conversion of image--signal--between the image.
Common laser printer is provided with in its casing or includes charging roller, photosensitive drums, laser scanning mechanism, developer roll, transfer roll and fixing roller etc.These component parts finally can form the different unit of integrated level according to manufacturer's purpose of design and technical thought separately.For example, consider factors such as task that each unit is born and technical life, charging roller, photosensitive drums etc. is prepared into an independently image forming process unit, also can claim photosensitive unit; Laser scanning mechanism, transfer roll and fixing roller then directly are installed in the laser printer respectively; Developer roll and powder feeding roller etc. are integrated into an independently developing apparatus, also claim developing cell or Delevoping cartridge.After photosensitive unit and developing cell are combined into a powder box that possesses image transitions ability and image developing ability simultaneously, standby in the printer of just can packing into.Perhaps, in view of holding the disposable operating characteristic of storing up carbon dust in the developing cell, and the developing apparatus concentrated area that comprises developer roll, powder feeding roller, powder-storage bin and waste powder hopper etc. is designed to a relatively independent replaceable member, make it with comprising the image forming process unit of charging roller, photosensitive drums or comprising that the laser printer of image forming process unit keeps dismountable movable connection method.Perhaps, further powder-storage bin and waste powder hopper are combined and be designed to individual member, certainly, also can be that powder-storage bin and waste powder hopper are designed to individual member respectively, make them keep dismountable movable connection method with the developing cell that comprises developer roll, powder feeding roller, for in time changing carbon dust, the durability that makes full use of parts such as developer roll, photosensitive drums facilitates.
In the course of the work, photosensitive drums charges to predetermined potential by charging roller, and response is formed corresponding to the electrostatic latent image for the treatment of print image on its cylindrical surface by the irradiation of laser scanning mechanism emitted laser bundle.
Store developer for example toner, ink powder or carbon dust within it in the container that the carbon dust tube is established, and utilize powder feeding roller and developer roll that carbon dust is sent to the corresponding region that photosensitive drums has electrostatic latent image, obtain the visual carbon dust image that naked eyes can be observed.
The carbon dust image that forms on the photosensitive drums is transferred on the paper of walking between the slit of photosensitive drums and transfer roll by transfer roll, utilizes fixing roller that the carbon dust image on the paper is given permanent photographic fixing at last.
For the split type developer reservoir that obtains because of the integrated level difference, it mainly utilizes the powder-storage bin of establishing in it to bear the storage task of carbon dust, and by puddle support and powder feeding screw carbon dust is transported to developer roll.This split type developer reservoir and the developing cell that comprises developer roll, powder feeding roller, and between the photosensitive unit at photosensitive drums place, generally take the separately mode of accumulating, then fit assembling during installation.The puddle support that is arranged in developer reservoir is made of the blade of back shaft and elastic material.Back shaft is bonding with usually adopting between the spring leaf, fusing mode is finished between the two fixing.This connected mode is not easy to change or repair when spring leaf is damaged, and bonding or welding mode all needs to use or be equipped with corresponding bonding agent, bonding apparatus or fusion apparatus simultaneously, causes the production cost to raise.
The utility model content
The utility model purpose is to provide a kind of laser printer developer reservoir.This developer reservoir needn't use complicated bonding or welding mode to come to provide between the two fixing to being arranged at its inner back shaft and spring leaf, thereby simplifies the back shaft of puddle support and the combination of spring leaf.
Laser printer developer reservoir according to the above-mentioned purpose design comprises box body and lid.Lid be fixed in box body uncovered on.Box body is provided with the developer feeding mouth of developer supplying turnover.Be provided with the puddle support that constitutes by back shaft and spring leaf in the box body.Puddle support rotatably is supported on two opposing sidewalls of box body by back shaft.The outer wall of back shaft is provided with the projection that laterally outwardly extends along back shaft.The position that projection is adjacent to the back shaft outer wall is provided with along the notch of back shaft sense of rotation indent.Spring leaf is provided with docking port corresponding to the position of projection.Docking port is being equal to or slightly greater than position in the same direction the radial dimension of projection corresponding to notch corresponding to the width on the back shaft sense of rotation.Spring leaf is nested on the position of projection corresponding to notch by its docking port.
Preferably, aforementioned laser printer developer reservoir, the outer wall of its back shaft are provided with the grab that laterally outwardly extends along back shaft.This grab is positioned on the back shaft sense of rotation with the relative position of notch.Spring leaf is inserted in the draw-in groove that is provided with on the grab back to an end of notch.
More preferably, aforementioned laser printer developer reservoir, the quantity of its projection is no less than two, and axially equidistantly distributing along back shaft.
Better, aforementioned laser printer developer reservoir, its docking port along the axial length of back shaft greater than docking port corresponding to the width on the back shaft sense of rotation.
Laser printer developer reservoir of the present utility model by the mode of notch and grab is set, cooperates the elasticity that blade possessed by elastic material on the puddle support back shaft, realized the activity butt joint between back shaft and the spring leaf.Under this docking mode, can realize stationary state preferably between back shaft and the spring leaf, wear out when spring leaf meets with simultaneously, when damaging, can change easily, repair, avoid causing scrapping whole puddle support because of blade damages.
