Developer supplying apparatus
A developer receiving apparatus includes a receiving portion displacably provided and configured to receive developer supplied from a supply container. The receiving portion including a receiving port configured to receive the developer and a first engaging portion engageable with the supply container to displace the receiving portion toward the supply container so as to connect the receiving portion with the supply container in a mounting operation. A covering member is displaceably provided in the receiving apparatus and covers an upper part of the receiving port. The covering member takes a closing position closing the upper part of the receiving port when the supply container is not mounted, and includes a second engaging portion engageable with the receiving portion to displace the covering member to a retracted position retracted from the closing position to permit the receiving portion to connect with the supply container in the mounting operation.
1. A developer receiving apparatus for receiving a developer supplied from a developer supply container which is detachably mountable to said developer receiving apparatus, said developer receiving apparatus comprising:
a receiving portion displacably provided in said receiving apparatus and configured to receive the developer supplied from the supply container, said receiving portion including a receiving port configured to receive the developer and a first engaging portion engageable with the supply container to displace said receiving portion toward the supply container so as to connect said receiving portion with the supply container in a mounting operation of the supply container; and
a covering member displacably provided in said receiving apparatus and covering an upper part of the receiving port, said covering member taking a closing position closing the upper part of said receiving port when the supply container is not mounted, and said covering member including a second engaging portion engageable with said receiving portion to displace said covering member to a retracted position retracted from the closing position to permit said receiving portion to connect with the supply container in the mounting operation of the supply container.
2. An apparatus according to claim 1 , wherein said covering member is provided with a rotational shaft supporting said covering member rotatably between the closing position and the retracted position, and said second engaging portion rotates said covering member about said rotational shaft with a movement of said receiving portion.
3. An apparatus according to claim 2 , further comprising a portion-to-be-engaged provided in said receiving portion engaged with said second engaging portion and provided with an engaging projection projecting in a direction perpendicular to said rotational shaft.
4. An apparatus according to claim 1 , wherein said covering member includes a first shield portion provided rotatably about a first rotational axis and configured to cover part of the upper part of said receiving port, and a second shield portion provided rotatably about a second rotational axis and configured to cover a remaining part of the upper part of said receiving port.
5. An apparatus according to claim 4 , wherein said first shield portion and said second shield portion are rotatable in opposite directions so as to separate from each other in the mounting operation of the supply container.
6. An apparatus according to claim 1 , further comprising an urging portion for urging said covering member in a direction from the retracted position to the closing position.
