Abstract

A printing apparatus includes: a conveyance part configured to convey a print medium in a first direction; a print head configured to perform printing by ejecting liquid onto the print medium conveyed by the conveyance part; a first stacking part configured to stack the print medium, on which printing has been performed by the print head, at a first position and at a second position different from the first position in a second direction intersecting with the first direction; and a liquid storage part configured to contain the liquid to be supplied to the print head. The liquid storage part is arranged above the first stacking part.

First claim

What is claimed is:

1 . A printing apparatus comprising:
a conveyance part configured to convey a print medium in a first direction; a print head configured to perform printing by ejecting liquid onto the print medium conveyed by the conveyance part; a first stacking part configured to stack the print medium, on which printing has been performed by the print head, at a first position and at a second position different from the first position in a second direction intersecting with the first direction; and a liquid storage part configured to contain the liquid to be supplied to the print head, wherein the liquid storage part is arranged above the first stacking part.

2 . The printing apparatus according to claim 1 further comprising
a waste liquid reservoir part configured to contain liquid that is discharged during maintenance of the print head,
wherein the waste liquid reservoir part is arranged below the first stacking part.

3 . The printing apparatus according to claim 2 ,
wherein the first stacking part moves in the first direction from an accommodated position.

4 . The printing apparatus according to claim 3 ,
wherein, in a state where the first stacking part has moved in the first direction from the accommodated position, the liquid storage part is arranged on an opposite side of the waste liquid reservoir part with respect to the first stacking part, as viewed from the downstream side in the first direction.

5 . The printing apparatus according to claim 3 further comprising
a movement mechanism configured to move the first stacking part in the second direction.

6 . The printing apparatus according to claim 1 ,
wherein the first stacking part at least partially overlaps with the liquid storage part in a height direction.

7 . The printing apparatus according to claim 3 further comprising
a second stacking part configured to stack the print medium on which printing has been performed by the print head,
wherein the first stacking part moves in the first direction relative to the second stacking part.

8 . The printing apparatus according to claim 7 further comprising
a movement mechanism configured to move the second stacking part in the second direction,
wherein the movement mechanism moves the first stacking part together with the second stacking part.

9 . The printing apparatus according to claim 1 ,
wherein the first stacking part does not move in the second direction.

10 . The printing apparatus according to claim 3 ,
wherein the first stacking part is drawn out by a user.

11 . The printing apparatus according to claim 1 ,
wherein the liquid storage part includes
a liquid container configured to contain the liquid to be supplied to the print head,
a base part on which the liquid container is to be mounted in a removable manner, and
a liquid container detection part configured to detect that the liquid container is mounted on the base part.

12 . The printing apparatus according to claim 11 ,
wherein the print head is capable of ejecting a plurality of types of liquid, wherein the liquid storage part includes a plurality of the liquid containers corresponding to the plurality of types of liquid, and wherein the plurality of the liquid containers is mounted on the base part side by side along the second direction in a removable manner.

13 . The printing apparatus according to claim 1 further comprising:
an operation button configured to receive an operation for performing the printing; and
a display part configured to display operation information corresponding to the operation performed on the operation button,
wherein the display part is arranged above the first stacking part.

14 . The printing apparatus according to claim 13 ,
wherein the display part is arranged above the first stacking part, on a side of the liquid storage part along the second direction.

15 . The printing apparatus according to claim 13 ,
wherein the operation button is arranged at a periphery of the display part above the first stacking part.

16 . The printing apparatus according to claim 1 further comprising:
a drive source; and
a drive transmission part configured to transmit a driving force from the drive source to the first stacking part,
wherein the drive transmission part is arranged on a side of the first stacking part along the second direction.

17 . The printing apparatus according to claim 7 ,
wherein the first stacking part is supported by the second stacking part.

18 . The printing apparatus according to claim 1 ,
wherein the second direction horizontally intersects with the first direction.

19 . A printing apparatus comprising:
a conveyance part configured to convey a print medium in a first direction; a print head configured to perform printing by ejecting liquid onto the print medium conveyed by the conveyance part; a first stacking part configured to be movable in the first direction from an accommodated position, and to stack the print medium, on which printing has been performed by the print head, at a first position and at a second position different from the first position in a second direction intersecting with the first direction; and a liquid storage part configured to contain liquid to be supplied to the print head, wherein the liquid storage part is arranged so as to overlap with the first stacking part.

20 . A printing apparatus comprising:
a conveyance part configured to convey a print medium in a first direction; a print head configured to perform printing by ejecting liquid onto the print medium conveyed by the conveyance part; a first stacking part configured to be movable in the first direction from an accommodated position, and to stack the print medium, on which printing has been performed by the print head, at a first position and at a second position different from the first position in a second direction intersecting with the first direction; and a waste liquid reservoir part configured to contain liquid that is discharged during maintenance of the print head, wherein the waste liquid reservoir part is arranged so as to overlap with the first stacking part.
