Abstract

The present disclosure aims to provide a technique for making it easy to clear a jam in a printing apparatus having a stacking unit configured to sort a printing medium in a direction orthogonal to a printing medium conveyance direction. One embodiment of the present disclosure is a printing apparatus having a casing, a conveyance unit housed in the casing and configured to convey a printing medium, and a stacking unit which is attached to the casing and on which a printing medium conveyed by the conveyance unit is be stacked. The stacking unit has a first stacking part movable in a second direction intersecting with a first direction in which a printing medium is conveyed and a second stacking part movable in the first direction relative to the first stacking part, and the stacking unit is detachable from the casing by moving in the first direction.

First claim

What is claimed is:

1 . A printing apparatus comprising:
a casing; a conveyance unit housed in the casing and configured to convey a printing medium; and a stacking unit which is attached to the casing and on which a printing medium conveyed by the conveyance unit is to be stacked, wherein the stacking unit has a first stacking part movable in a second direction intersecting with a first direction in which a printing medium is conveyed and a second stacking part movable in the first direction relative to the first stacking part, and the stacking unit is detachable from the casing by moving in the first direction.

2 . The printing apparatus according to claim 1 , further comprising a control unit, wherein
the control unit moves the first stacking part in the second direction and moves the second stacking part in the first direction.

3 . The printing apparatus according to claim 2 , further comprising a detection unit configured to detect whether the stacking unit is attached to the casing or is detached from the casing.

4 . The printing apparatus according to claim 3 , further comprising an operation unit configured to be operated by a user, wherein
the operation unit has a display panel used to display information based on a result of detection by the detection unit and an operation button used to select or execute an item displayed on the display panel.

5 . The printing apparatus according to claim 4 , further comprising a determination unit configured to determine, in a case where a jam occurs, whether the stacking unit is detached based on the result of detection by the detection unit, wherein
in a case where the determination unit determines that the stacking unit is not detached, the control unit displays, on the display panel, a user interface prompting the user to detach the stacking unit.

6 . The printing apparatus according to claim 5 , wherein
in a case where the determination unit determines that the stacking unit is detached, the control unit displays, on the display panel, a user interface showing how to perform jam processing.

7 . The printing apparatus according to claim 6 , wherein
above the stacking unit, there is a conveyance path for a printing medium to be printed on both sides.

8 . The printing apparatus according to claim 7 , wherein
detaching the stacking unit from the casing exposes the conveyance path.

9 . The printing apparatus according to claim 8 , wherein
by moving the first stacking part in the second direction, the stacking unit is capable of sorting a printing medium at positions different in the second direction.

10 . The printing apparatus according to claim 9 , wherein
the stacking unit has a first drive train configured to transmit a drive force for moving the first stacking part in the second direction, the casing has a drive source and a second drive train, and with the stacking unit attached to the casing, the first drive train and the second drive train mesh with each other.

11 . The printing apparatus according to claim 10 , further comprising a press unit configured to determine a position of the stacking unit relative to the casing, wherein
with the stacking unit attached to the casing, the stacking unit receives a force from the press unit in a direction in which the first drive train is pressed against the second drive train.

12 . The printing apparatus according to claim 11 , wherein
a drive train meshing part where the first drive train and the second drive train mesh with each other is located at one side of the casing in terms of the second direction, and the press unit is located at an opposite side of the casing in terms of the second direction.

13 . The printing apparatus according to claim 12 , wherein
with the stacking unit attached to the casing, the stacking unit receives a force from the press unit in a direction opposite from the first direction.

14 . The printing apparatus according to claim 13 , further comprising a printing unit housed in the casing and configured to print an image on a printing medium conveyed by the conveyance unit.

15 . A printing apparatus comprising:
a casing; a conveyance unit housed in the casing and configured to convey a printing medium; and a stacking unit which is attached to the casing and on which a printing medium conveyed by the conveyance unit is to be stacked, wherein the stacking unit is movable in a second direction intersecting with a first direction in which a printing medium is conveyed, and a conveyance path in the conveyance unit is exposed in a case where the stacking unit is detached from the casing.

16 . A control method for controlling a printing apparatus having
a casing, a conveyance unit housed in the casing and configured to convey a printing medium, and a stacking unit on which a printing medium conveyed by the conveyance unit is to be stacked, the stacking unit having a first stacking part movable in a second direction intersecting with a first direction in which a printing medium is conveyed and a second stacking part movable in the first direction relative to the first stacking part, the stacking unit being detachable from the casing by moving in the first direction, the control method comprising: moving the first stacking part in the second direction and moving the second stacking part in the first direction.

17 . A non-transitory computer readable storage medium storing a program which causes a computer to execute a control method for controlling a printing apparatus having
a casing, a conveyance unit housed in the casing and configured to convey a printing medium, and a stacking unit on which a printing medium conveyed by the conveyance unit is to be stacked, the stacking unit having a first stacking part movable in a second direction intersecting with a first direction in which a printing medium is conveyed and a second stacking part movable in the first direction relative to the first stacking part, the stacking unit being detachable from the casing by moving in the first direction, the control method comprising: moving the first stacking part in the second direction and moving the second stacking part in the first direction.
