Abstract

A sheet storage apparatus according to an embodiment of the present invention includes a receiving unit which receives a sheet that is discharged from a discharge port at a position below the discharge port, and a sheet butting unit which is provided in the vicinity of the receiving unit and receives a front end portion of the sheet. The sheet butting unit has a projection which is provided on at least one of an inner side surface and an inner upper surface of the sheet butting unit. The projection is configured to be capable of retaining a state of regulating vertically upward movement of the front end portion of the sheet being discharged from the discharge port.

First claim

What is claimed is:

1 . A sheet storage apparatus comprising:
a receiving unit configured to receive a sheet being discharged from a discharge port at a position below the discharge port; and a sheet butting unit provided in the vicinity of the receiving unit and configured to receive a front end portion of the sheet; wherein the sheet butting unit has a projection provided on at least one of an inner side surface and an inner upper surface of the sheet butting unit, and the projection is configured to be capable of retaining a state of regulating vertically upward movement of the front end portion of the sheet being discharged from the discharge port.

2 . The sheet storage apparatus according to claim 1 , wherein a plurality of the projections provided on the inner side surface are arranged in a vertical direction.

3 . The sheet storage apparatus according to claim 1 , wherein a plurality of the projections provided on the inner upper surface are arranged in a discharge direction of the sheet.

4 . The sheet storage apparatus according to claim 2 , wherein the plurality of the projections provided on the inner side surface are formed such that the projection located at a vertically upper part has a larger height.

5 . The sheet storage apparatus according to claim 3 , wherein the plurality of the projections provided on the inner upper surface have heights such that the projection among the arranged projections which is located on the most downstream side in the discharge direction of the sheet is formed higher than the rest of the projections.

6 . The sheet storage apparatus according to claim 1 , wherein the height of the projection is greater than a value obtained by multiplying a maximum thickness of the sheet to be possibly used by a maximum number of the sheets to be possibly used.

7 . A printing apparatus comprising:
a roll holder unit configured to rotatably hold a roll of sheets; a printing unit configured to perform printing on a sheet reeled out and conveyed from the roll held by the roll holder unit; a discharge port configured to discharge the sheet printed by the printing unit; and a sheet storage apparatus configured to receive the sheet discharged from the discharge port, the sheet storage apparatus comprising:
a receiving unit configured to receive the sheet being discharged from the discharge port at a position below the discharge port, and
a sheet butting unit provided in the vicinity of the receiving unit and configured to receive a front end portion of the sheet,
wherein the sheet butting unit has a projection provided on at least one of an inner side surface and an inner upper surface of the sheet butting unit, and
the projection is configured to be capable of retaining a state of regulating vertically upward movement of the front end portion of the sheet being discharged from the discharge port.
