Abstract

An apparatus includes a container configured to store a liquid to be supplied to a discharge unit, a first cover portion capable of moving between a closing position where an inlet portion in the container is covered and an opening position, a second cover portion capable of moving between a closing position where the first cover portion is covered and an opening position where the first cover portion is exposed so as to be opened/closed, and a valve which opens/closes a passage communicating with an inside of the container. The valve closes the passage interworking with a movement of the first cover portion to the opening position, and opens the passage interworking with a movement of the second cover portion to the closing position.

Claims (34)

1. A printing apparatus comprising:

a container including a chamber configured to store ink to be supplied to a printhead configured to discharge the ink, and an inlet hole for injecting the ink into the chamber; and

a cap member including a seal portion configured to detachably seal the inlet hole by being inserted into the inlet hole, the cap member configured to be swingably supported with a shaft portion;

wherein the seal portion contacts an inner wall surface of the inlet hole in a state where the seal portion is inserted into the inlet hole,

wherein a plurality of grooves is formed in the seal portion and provided at equal intervals in a circumferential direction,

wherein the cap member is moved between an opening position to open the inlet hole and a closing position to close the inlet hole, and

wherein the plurality of grooves formed in the seal portion is exposed in a state where the cap member is in the opening position.

2. The printing apparatus according to claim 1 , wherein the plurality of grooves is formed so as to hold a seal liquid applied to the seal portion.

3. The printing apparatus according to claim 2 , wherein the seal liquid contains a hygroscopic component.

4. The printing apparatus according to claim 1 , further comprising a top cover configured to cover a top of the printing apparatus,

wherein a direction of rotation for opening the top cover is the same as a direction of rotation for opening the cap member.

5. The printing apparatus according to claim 1 , further comprising a tank cover configured to cover the container and the cap member.

6. The printing apparatus according to claim 5 , further comprising a second container including a second chamber configured to store ink to be supplied to the printhead,

wherein the tank cover is configured to cover the second container.

7. The printing apparatus according to claim 6 , further comprising a conveying roller configured to convey a print medium in a first direction,

wherein the container and the second container are arrayed in a second direction intersecting the first direction.

8. The printing apparatus according to claim 6 , further comprising a carriage configured to carry the print head in a second direction,

wherein the container and the second container are arrayed in the second direction.

9. The printing apparatus according to claim 1 , wherein a remaining amount of ink stored in the chamber is visible on a front of the printing apparatus.

10. The printing apparatus according to claim 1 , further comprising an operation unit configured to accept a user operation.

11. The printing apparatus according to claim 1 , further comprising a valve configured to open/close a passage from the chamber to the printhead.

12. The printing apparatus according to claim 1 , further comprising a tube for supplying the ink in the chamber to the printhead.

13. The printing apparatus according to claim 1 , wherein a bottle is inserted into the inlet hole for injecting the ink into the chamber.

14. The printing apparatus according to claim 1 , further comprising a recovery unit configured to recover the printhead.

15. The printing apparatus according to claim 1 , further comprising the printhead.

16. The printing apparatus according to claim 1 , wherein the inlet hole is cylindrical.

17. A printing apparatus comprising:

a container including a chamber configured to store ink to be supplied to a printhead configured to discharge the ink, and an inlet hole for injecting the ink into the chamber; and

a cap member including a seal portion configured to detachably seal the inlet hole by being inserted into the inlet hole, the cap member configured to be swingably supported with a shaft portion;

wherein the seal portion contacts an inner wall surface of the inlet hole in a state where the seal portion is inserted into the inlet hole,

wherein a plurality of grooves is formed in the seal portion and provided at equal intervals in a circumferential direction,

wherein a bottle is inserted into the inlet hole for injecting the ink into the chamber,

wherein the ink in the bottle is injected into the container via a tube portion standing in the inlet hole, and

wherein the seal portion is between the tube portion and the inner wall surface of the inlet hole in a state where the seal portion is inserted into the inlet hole.
