Abstract

According to one embodiment, a sheet cassette includes a sheet placing portion. The sheet placing portion can rotate around a rotation shaft while placing a sheet of a placeable maximum size in a sheet placing area to be flat. The rotation shaft extends to be perpendicular to a discharge direction and a gravity direction of the sheet. The rotation shaft is disposed between a first end portion on a downstream side along the discharge direction in the sheet placing area and a second end portion on an upstream side positioned on a side opposite to the first end portion.

First claim

What is claimed is:

1 . A sheet cassette, comprising:
a sheet placing portion configured to rotate around a rotation shaft while a sheet of a placeable maximum size is placed in a sheet placing area that is flat, and wherein the rotation shaft extends perpendicularly to a discharge direction and a gravity direction of the sheet and is positioned between a first end portion on a downstream side along the discharge direction in the sheet placing area and a second end portion on an upstream side positioned on a side opposite to the first end portion.

2 . The sheet cassette according to claim 1 , further comprising:
side guides configured to be in contact with an end portion of the sheet in a direction parallel to a placing surface of the sheet placing area and perpendicular to the discharge direction, wherein the side guide is configured to rotate together with the sheet placing portion.

3 . The sheet cassette according to claim 1 , further comprising:
an end guide configured to be in contact with an end portion on an upstream side of the sheet along the discharge direction, wherein the end guide is configured to rotate together with the sheet placing portion.

4 . The sheet cassette according to claim 1 ,
wherein the sheet placing portion rotates by an input of external force so that the first end portion is disposed above the second end portion, a center of gravity of the sheet placing portion is on a downstream side in the discharge direction with respect to the rotation shaft, and the sheet placing portion rotates by gravity when the input of the external force is terminated.

5 . The sheet cassette according to claim 4 , further comprising:
a regulation member configured to regulate disposition of the first end portion below the second end portion, when the sheet placing portion rotates by gravity.

6 . The sheet cassette according to claim 5 , further comprising:
a cushioning member configured to alleviate an impact by the regulation of the regulation member.

7 . An image processing device, comprising:
an image forming component; and a sheet cassette, comprising:
a sheet placing portion configured to rotate around a rotation shaft while a sheet of a placeable maximum size is placed in a sheet placing area that is flat, and
wherein the rotation shaft extends perpendicularly to a discharge direction and a gravity direction of the sheet and is positioned between a first end portion on a downstream side along the discharge direction in the sheet placing area and a second end portion on an upstream side positioned on a side opposite to the first end portion.

8 . The image processing device according to claim 7 , further comprising:
a first cassette storage component configured not to store the sheet cassette; and a second cassette storage component formed below the first cassette storage component and configured to store the sheet cassette.

9 . The image processing device according to claim 8 , further comprising:
a third cassette storage component formed below the second cassette storage component and configured to not to store the sheet cassette.

10 . The image processing device according to claim 7 , further comprising:
side guides configured to be in contact with an end portion of the sheet in a direction parallel to a placing surface of the sheet placing area and perpendicular to the discharge direction, wherein the side guide is configured to rotate together with the sheet placing portion.

11 . The image processing device according to claim 7 , further comprising:
an end guide configured to be in contact with an end portion on an upstream side of the sheet along the discharge direction, wherein the end guide is configured to rotate together with the sheet placing portion.

12 . The image processing device according to claim 7 ,
wherein the sheet placing portion rotates by an input of external force so that the first end portion is disposed above the second end portion, a center of gravity of the sheet placing portion is on a downstream side in the discharge direction with respect to the rotation shaft, and the sheet placing portion rotates by gravity when the input of the external force is terminated.

13 . The image processing device according to claim 12 , further comprising:
a regulation member configured to regulate disposition of the first end portion below the second end portion, when the sheet placing portion rotates by gravity.

14 . The image processing device according to claim 13 , further comprising:
a cushioning member configured to alleviate an impact by the regulation of the regulation member.

15 . An image processing device, comprising:
an image forming component; a sheet cassette, comprising:
a sheet placing portion configured to rotate around a rotation shaft while a sheet of a placeable maximum size is placed in a sheet placing area that is flat, and
wherein the rotation shaft extends perpendicularly to a discharge direction and a gravity direction of the sheet and is positioned between a first end portion on a downstream side along the discharge direction in the sheet placing area and a second end portion on an upstream side positioned on a side opposite to the first end portion,
the sheet placing portion rotates by an input of external force so that the first end portion is disposed above the second end portion,
a center of gravity of the sheet placing portion is on a downstream side in the discharge direction with respect to the rotation shaft, and
the sheet placing portion rotates by gravity when the input of the external force is terminated; and
a cassette storage component configured to store the sheet cassette, wherein, when the sheet cassette is pulled out from the cassette storage component, the sheet placing portion rotates by gravity.

16 . The image processing device according to claim 15 , further comprising:
a regulation member configured to regulate disposition of the first end portion below the second end portion, when the sheet placing portion rotates by gravity.

17 . The image processing device according to claim 16 , further comprising:
a cushioning member configured to alleviate an impact by the regulation of the regulation member.

18 . The image processing device according to claim 15 , further comprising:
a first cassette storage component configured not to store the sheet cassette; and a second cassette storage component formed below the first cassette storage component and configured to store the sheet cassette.

19 . The image processing device according to claim 18 , further comprising:
a third cassette storage component formed below the second cassette storage component and configured to not to store the sheet cassette.

20 . The image processing device according to claim 15 , further comprising:
an end guide configured to be in contact with an end portion on an upstream side of the sheet along the discharge direction, wherein the end guide is configured to rotate together with the sheet placing portion.
