Description
Technical Field
The present invention relates to a developer supply container detachably mountable to a developer receiving apparatus, capable of being used with an electrophotographic image forming apparatus (e.g., a copying machine, a facsimile machine, a printer, or a complex machine having a plurality of functions of the copying machine, the facsimile machine, and a printer).
Background
An electrophotographic image forming apparatus generally has an image processing unit and a developing unit, and develops an electrostatic latent image formed on the image processing unit with a developer (toner) such as carbon powder supplied from the developing unit to form a visible image on a medium such as paper. In which the developer is required to be constantly replenished into the electrophotographic image forming apparatus as a consumable. A supply container having a container accommodating a certain amount of developer, which is detachably mounted to a developing unit in an electrophotographic image forming apparatus, is generally used to supply the developer to the developing unit.
Referring to fig. 1 and 2, fig. 1 and 2 are an exploded view and a sectional view of a developer supply container detachably mountable to a developer replenishing apparatus as disclosed in the prior art. The developer supply container 100 includes: a housing portion 110 for housing a developer; a feeding portion 120 for feeding the developer in the accommodating portion 110 along with rotation of the feeding portion 120; a discharge chamber 130 provided with a discharge port 131 for allowing the developer fed by the feeding portion 120 to be discharged; a pump section 140 for acting on at least the discharge chamber 130 and having a volume that changes with the reciprocating movement; a driving force receiving portion 111 for receiving a rotational force for rotating the housing portion 110 from the developer replenishing apparatus; a drive conversion portion 150 for converting the rotational force received by the driving force receiving portion 111 into a force for operating the pump portion 140.
Wherein the pump portion 140 is stretchable and this stretching is sufficient to change the internal pressure of the developer supply container 100 by utilizing the volume change. The driving conversion part 150 drives the pump part 140 to perform axial expansion and contraction, and drives the air pressure inside the developer supply container 100 to reciprocally change between positive and negative pressure. The developer flows out from the discharge port 131 and enters the developing unit by the positive pressure of the pump portion 140. When the pump 140 returns to its original state, the negative pressure drives the developer in the developer supply container 100, so that the developer in the developer supply container is kept in a fluffy state, and caking is avoided.
However, the pump part 140 has a volume that varies with the reciprocating movement to change the internal pressure of the developer supply container 100, and can only intermittently supply the developer to the discharge port 131, resulting in uneven supply of the developer, affecting the printing and copying quality of the image forming apparatus. Further, in the process of returning the pump portion 140 to the original state, the negative pressure may suck the developer back, and the supply of the developer may be not smooth. Further, after a plurality of operations of the reciprocating movement of the pump section 140, the telescopic performance of the pump section 140 may be lowered, and thus the supply of the developer may be uneven.
Also, the pump part 140 moves continuously in the axial direction of the supply container, and the junction thereof with the wall part of the discharge chamber 130 is also often loosened due to the presence of axial tension, resulting in leakage of the developer.

Meanwhile, the driving gear 214 rotates the auxiliary gear 262 'in association with the rotation of the housing cylinder 21, thereby driving the first worm gear 263' to rotate synchronously, and simultaneously driving the second worm gear 271 'to rotate synchronously, thereby driving the worm 27'. Since the peripheral surface of the worm 27 'has the groove portion 272' extending in the axial direction of the worm 27 'in a spiral shape, the groove portion 272' can keep the developer in the discharge chamber 233 in a fluffy state during the rotation of the worm 27 'to avoid caking, and the groove portion 272' drives the developer in the discharge chamber 233 to move toward the discharge port 234. Meanwhile, the cam 264 accompanies the rotation of the auxiliary gear 262' to drive the moving lever 29 to move up and down in the axial direction, specifically, when the protruding portion of the cam 264 is pressed against the front end surface 292 of the moving lever 29, the moving lever 29 moves down in the axial direction, the tip 291 of the moving lever 29 is inserted into the discharge port 234, and the tension spring is in a stretched state; when the wheel portion of the cam 264 is pressed against the front end surface 292 of the moving lever 29, the tension spring is reset from the stretched state, thereby driving the moving lever 29 to move upward in the axial direction. The moving lever 29 moves up and down in the axial direction with the rotation of the cam 264, so that the developer in the discharge chamber 233 is kept in a fluffy state, and the developer in the discharge chamber 233 is driven to move toward the discharge port 234, whereby the developer flows into the developer replenishing apparatus through the through hole 241 communicating with the discharge port 234, and the developer is continuously and uniformly supplied to the developer replenishing apparatus.
The developer supply container 2' of the present invention has a simple and practical structure, and effectively ensures that the developer is continuously and uniformly supplied to the developer replenishing apparatus. Further, the end 291 of the moving lever 29 is conically fitted to the discharge port 234, which is more advantageous for continuous and uniform supply of the developer. Meanwhile, the discharging cavity 233 is a closed cavity, so that leakage of the developer is effectively avoided, and good sealing performance is achieved.
The above embodiments are only preferred examples of the present invention and are not intended to limit the scope of the present invention, so that all equivalent changes or modifications made according to the construction, characteristics and principles of the present invention shall be included in the scope of the present invention.
