Description
Technical field
The utility model relates to for example developer box of usefulness such as laser printer of electrophotographic image forming.
Background technology
The image developing apparatus of laser printer needs to be equipped with developer box or the cartridge that is used to store developer usually when work.This carbon dust and often be designed to change or through reclaim filling the form that can be repeatedly used behind the carbon dust, its relative configurations be can dismounting a plurality of assemblies.
In a kind of structure of existing developing apparatus, the cartridge outward appearance that is used to store carbon dust is rendered as the cylindrical drum form basically, and it is made of the guard shield that is used to store the inner core of carbon dust and be used for the cartridge location and have a certain protective role.Guard shield is placed on the cylindrical outer wall of inner core.On the cylindrical wall of inner core, offer the carbon dust supply port, in the inner chamber of inner core, be provided with the puddle support that is used to stir carbon dust.In the developing apparatus frame that is used to support cartridge, be formed with carbon dust supply orifice corresponding to inner core carbon dust supply port.This carbon dust supply orifice docks with inner core carbon dust supply port coupling, provides carbon dust to be entered the carbon dust transmission channel of developing room by inner core.Form developing room after the frame closure of developing apparatus.In this developing room, dispose the carbon dust donor rollers and the developer roll that adjoin each other.So, after carbon dust supply orifice and inner core carbon dust supply port coupling dock, the carbon dust of being imported by inner core carbon dust supply port transferred to developer roll by the carbon dust donor rollers.
In the developing room of above-mentioned developing apparatus, overhangingly on development chamber wall go out sheet component.Corresponding to the cylindrical surface of developer roll, this sheet component has along the axially extended linearity of developer roll edge.This linearity edge contacts with the developer roll cylindrical surface, and radially applies certain pressure along developer roll, is attached to carbon dust layer thickness on the developer roll cylindrical surface with adjusting.With respect to developer roll, photosensitive drums and inner core carbon dust supply port are opposite to the both sides of developer roll respectively, and the cylindrical drum face of photosensitive drums and the cylindrical surface of developer roll are in contact with one another.The image information of laser printer output by the cylindrical drum face of Laser Transmission to photosensitive drums, forms electrostatic latent image by corresponding laser scanning device.And then the electrostatic latent image supply carbon dust of developer roll on photosensitive drums drum face, latent electrostatic image developing is become visual image.Thereafter, the visual image rotation on the photosensitive drums drum face replaces to transfer position, by corresponding transfer roll visual image is transferred on the recording medium such as paper, forms the image information of clerking.
Has detent mechanism between the storage powder inner core of aforementioned cartridge and the guard shield.This detent mechanism will store up the powder inner core and guard shield is combined into a complete cartridge, allows storage powder inner core and the reciprocal rotation of guard shield in common axis of rotation is done the certain angle scope simultaneously.Corresponding to inner core carbon dust supply port, guard shield is provided with the On/Off device.This On/Off device is opening and the sponge seal that sets gradually along the guard shield circumferencial direction.In above-mentioned rotational angle range, the On/Off device on the guard shield cooperates the reciprocal rotating opening of guard shield or closes inner core carbon dust supply port, realizes flowing of carbon dust or flowing of blocking-up carbon dust.
In order to realize and the cooperating of laser printer developing device, the detent mechanism of mutual coupling need be set simultaneously on developing apparatus and above-mentioned cartridge usually.This detent mechanism is fixed in the appropriate location of developing apparatus with cartridge, and to realize the stable supply of carbon dust, it is locating convex block and the detent that is arranged at respectively on developing apparatus and the cartridge, perhaps detent and locating convex block.Generally speaking, be that locating convex block is set on cartridge.The visual different type of machines of locating convex block on the cartridge is disposed on storage powder inner core or the guard shield.When locating convex block was disposed on the guard shield, the cartridge in the developing apparatus of packing into was realized the carbon dust supply by the reciprocal rotation of its storage powder inner core.When locating convex block was disposed on the storage powder inner core, the cartridge in the developing apparatus of packing into was realized the carbon dust supply by the reciprocal rotation of its guard shield.For a kind of situation in back, because storage powder inner core need provide airtight function with respect to carbon dust, the material of therefore storing up the powder inner core adopts softer acrylic plastering relatively usually.Thus, with the integrally formed locating convex block of storage powder inner core, its each several part variable thickness, the intensity of inaccessible requirement, very easily be worn through in the cartridge position fixing process or be out of shape, the lighter causes carbon dust to leak, and pollutes printer and recording medium, weight person causes the cartridge location inaccurate, in use forms and back and forth rocks.
