Abstract
A sheet processing apparatus in an embodiment includes a processing unit, a tray, alignment members, and a supporting member. The processing unit processes regular size sheets. The regular size sheets can be placed on a first surface of the tray. The alignment members are capable of coming into contact with end portions in a first direction, in which a line of intersection of the first surface and a horizontal plane extends, further in an upward direction than a center of gravity of a largest regular size sheet present in an initial position where the regular size sheet entering the tray is placed first. The supporting member supports a lower end portion of the largest regular size sheet and extends from inner sides to outer sides of end portions of the largest regular size sheet in the first direction.
Claims20
A sheet processing apparatus, comprising:
- a processing component configured to process regular size sheets;
- a tray having a first surface on which the regular size sheets are placeable;
- alignment members configured to, if a direction in which a line of intersection of the first surface and a horizontal plane extends is represented as a first direction, a direction parallel to the first surface and perpendicular to the first direction is represented as a second direction, the regular size sheet having a largest length in the second direction among the regular size sheets placed on the tray is represented as a largest regular size sheet, and a position in the second direction where the regular size sheet entering the tray is placed first is represented as an initial position, come into contact with end portions in the first direction further in an upward direction than a center of gravity of the largest regular size sheet present in the initial position;
- and
- a supporting member configured to support a lower end portion of the largest regular size sheet, the supporting member extends from inner sides to outer sides of end portions of the largest regular size sheet in the first direction.
An image forming apparatus, comprising:
- an image forming component;
- and
- a sheet processing apparatus, comprising:
- a processing component configured to process regular size sheets;
- a tray having a first surface on which the regular size sheets are placeable;
- alignment members configured to, if a direction in which a line of intersection of the first surface and a horizontal plane extends is represented as a first direction, a direction parallel to the first surface and perpendicular to the first direction is represented as a second direction, the regular size sheet having a largest length in the second direction among the regular size sheets placed on the tray is represented as a largest regular size sheet, and a position in the second direction where the regular size sheet entering the tray is placed first is represented as an initial position, come into contact with end portions in the first direction further in an upward direction than a center of gravity of the largest regular size sheet present in the initial position;
- and
- a supporting member configured to support a lower end portion of the largest regular size sheet, the supporting member extends from inner sides to outer sides of end portions of the largest regular size sheet in the first direction.
A sheet processing method for processing regular size sheets, comprising:
- placing the regular size sheets on a first surface of a tray;
- if a direction in which a line of intersection of the first surface and a horizontal plane extends is represented as a first direction, a direction parallel to the first surface and perpendicular to the first direction is represented as a second direction, the regular size sheet having a largest length in the second direction among the regular size sheets placed on the tray is represented as a largest regular size sheet, and a position in the second direction where the regular size sheet entering the tray is placed first is represented as an initial position, bringing alignment members into contact with end portions in the first direction further in an upward direction than a center of gravity of the largest regular size sheet present in the initial position;
- and
- supporting a lower end portion of the largest regular size sheet with a supporting member, the supporting member extending from inner sides to outer sides of end portions of the largest regular size sheet in the first direction.
