Abstract

A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

First claim

What is claimed is:

1. A printing apparatus comprising:
a first tank configured to contain liquid to be supplied to a printhead, the first tank including a first injection port through which the liquid is injected;
a second tank configured to contain liquid to be supplied to the printhead, the second tank including a second injection port through which the liquid is injected;
a first holder configured to hold a first cap for capping the first injection port; and
a second holder configured to hold a second cap for capping the second injection port,
wherein the second tank is provided adjacent to the first tank,
wherein the first holder has an opening through which the first cap is exposed from a front side of the printing apparatus, and
wherein the first holder includes a concave portion on a surface facing the second holder.

2. The printing apparatus according to claim 1 , wherein the concave portion faces a side surface of a bottle for injecting the liquid into the second tank through the second injection port, in a state where the first cap caps the first injection port and the second cap does not cap the second injection port.

3. The printing apparatus according to claim 2 , wherein the concave portion does not contact with the side surface of the bottle in a state where the first cap caps the first injection port and the second cap does not cap the second injection port.

4. The printing apparatus according to claim 2 , wherein the concave portion is curved along the side surface of the bottle.

5. The printing apparatus according to claim 1 , further comprising a holding portion configured to hold the first holder at a position where the first cap does not cap the first injection port.

6. The printing apparatus according to claim 5 , wherein the holding portion causes the first holder to elastically deform and ride onto the holding portion to hold the first holder at the position.

7. The printing apparatus according to claim 1 , the first holder is movable between a first position where the first cap caps the first injection port and a second position where the first cap does not cap the first injection port.

8. The printing apparatus according to claim 7 , wherein the first holder is rotatable between the first position and the second position.

9. The printing apparatus according to claim 1 , further comprising a conveyance roller configured to convey a print medium in a conveyance direction,
wherein the first tank and the second tank are arrayed in a direction crossing the conveyance direction.

10. The printing apparatus according to claim 1 , further comprising a conveyance roller configured to convey a print medium in a conveyance direction,
wherein the first tank and the second tank are provided downstream of the conveyance roller in the conveyance direction.

11. The printing apparatus according to claim 1 , wherein the first holder is color-coded in a color corresponding to a color of the liquid in the first tank.

12. The printing apparatus according to claim 1 , wherein the first tank includes a first chamber containing the liquid and a second chamber containing air.

13. The printing apparatus according to claim 1 , further comprising a tube configured to connect the first tank and the printhead.

14. The printing apparatus according to claim 1 , further comprising the print head.

15. The printing apparatus according to claim 1 , further comprising a carriage configured to carry the print head in a scanning direction.

16. A printing apparatus comprising:
a first tank configured to contain liquid to be supplied to a printhead, the first tank including a first injection port through which the liquid is injected;
a second tank configured to contain liquid to be supplied to the printhead, the second tank including a second injection port through which the liquid is injected;
a first holder configured to hold a first cap for capping the first injection port;
a second holder configured to hold a second cap for capping the second injection port, and
a holding portion configured to hold the first holder at a position where the first cap does not cap the first injection port,
wherein the second tank is provided adjacent to the first tank,
wherein the first holder includes a concave portion on a surface facing the second holder, and
wherein the holding portion causes the first holder to elastically deform and ride onto the holding portion to hold the first holder at the position.
