Abstract

A photographic developer container can be detachably mounted to a photographic developer receiving portion located within an image-forming apparatus. The photographic developer receiving portion includes a receiving opening, a binding portion, and an abutting portion. The photographic developer container includes a photographic developer discharge portion arranged with a discharge opening configured for discharging the photographic developer of the photographic developer container body; a photographic developer blocking portion arranged with a hole; and a lifting portion.

Claims (20)

1 . A photographic developer container, wherein the photographic developer container can be detachably mounted to a photographic developer receiving portion located within an image-forming apparatus; the photographic developer receiving portion comprises a receiving opening for receiving a photographic developer, a binding portion capable of integrally displacing with the photographic developer receiving portion, and an abutting portion that supports the binding portion, wherein

the photographic developer container comprises:

a photographic developer container body configured for containing the photographic developer and capable of rotating around a first rotation axis;

a photographic developer discharge portion arranged with a discharge opening configured for discharging the photographic developer of the photographic developer container body;

a photographic developer blocking portion arranged with a hole that can communicate with the discharge opening and configured to open and close the discharge opening along with a mounting and dismounting operation of the photographic developer container;

a displacement portion extending along a first direction of the photographic developer discharge portion;

a guiding portion extending along a second direction of the photographic developer discharge portion; and

a lifting portion capable of cooperating with the photographic developer receiving portion, such that the lifting portion moves a predetermined distance in the first direction, and the lifting portion rotates around itself at a predetermined angle, causing the receiving opening to fluidly communicate with the discharge opening.

2 . The photographic developer container according to claim 1 , further comprising a resetting portion, connected to the lifting portion and configured to enable resetting of the lifting portion along with the dismounting operation of the photographic developer container.

3 . The photographic developer container according to claim 1 , wherein the predetermined distance is equal to a distance of movement of the binding portion cooperating with the displacement portion through the lifting portion from a first state to a third state.

4 . The photographic developer container according to claim 1 , wherein the predetermined angle is equal to an offset angle of the binding portion cooperating with the guiding portion through the lifting portion from a first state to a third state.

5 . The photographic developer container according to claim 1 , wherein the photographic developer blocking portion is connected to the lifting portion, so that the lifting portion drives the photographic developer blocking portion to move, thereby causing the photographic developer blocking portion to move to a position where the hole and the receiving opening are communicated so that the discharge opening and the receiving opening are communicated.

6 . The photographic developer container according to claim 5 , wherein the lifting portion is connected with a snapping part, the snapping part is provided at a moving end of the lifting portion and extends in the second direction towards the discharge opening; and the photographic developer blocking portion further comprises a snapped part configured to cooperate with the snapping part, so that the lifting portion drives the photographic developer blocking portion to move in the first direction.

7 . The photographic developer container according to claim 6 , wherein the snapping part and the lifting portion are integrally molded.

8 . The photographic developer container according to claim 1 , wherein the photographic developer blocking portion is connected to the lifting portion, so that the photographic developer blocking portion drives the lifting portion to move, thus causing the photographic developer blocking portion to move to a position where the hole and the receiving opening are in a communicating state so that the discharge opening and the receiving opening are communicated.

9 . The photographic developer container according to claim 8 , wherein the lifting portion is connected with a pushing portion provided at a moving end of the lifting portion and extends in a third direction towards a horizontal plane of the discharge opening; and the photographic developer blocking portion further comprises a pushing member configured to cooperate with the pushing portion, so that the photographic developer blocking portion drives the lifting portion to move in the first direction.

10 . The photographic developer container according to claim 9 , wherein the pushing portion and the lifting portion are integrally molded.

11 . An image-forming apparatus, comprising

a photographic developer receiving portion and the photographic developer container according to claim 1 ; and

the photographic developer container is detachably mounted on the photographic developer receiving portion.
