Abstract
A sheet feeding apparatus includes a sheet containing unit and a sheet feeding device to feed sheets in the sheet containing unit. The sheet containing unit includes a main body to hold sheets, a drawer member capable of being drawn from the main body, a restricting member movable in a direction parallel to a sheet feeding direction, a first retaining member disposed at the main body, and a second retaining member disposed at the drawer member. The drawer member holds the sheets together with the main body when drawn from the main body. The restricting member restricts an upstream end position of the contained sheets. The first retaining member retains the restricting member at a first position. The second retaining member retains the restricting member at a second position.
Claims14
A sheet feeding apparatus comprising:
- a sheet stacking plate on which sheets are to be stacked;
- a cassette main body configured to support the sheet stacking plate;
- a regulating device disposed at the cassette main body to be movable in a first direction and movable in a second direction opposite to the first direction, and configured to regulate an end position of the sheets;
- a plurality of first engaged portions disposed at the cassette main body in a moving direction in which the regulating device is configured to move;
- and
- a plurality of second engaged portions disposed at the cassette main body in the moving direction of the regulating device, wherein the plurality of second engaged portions are arranged at positions separated from the plurality of first engaged portions with respect to a direction intersecting the moving direction of the regulating device,
- wherein the regulating device includes:
- a holding member,
- a lever disposed rotatably at the holding member and configured to be operated,
- a first elastic member,
- a first engaging portion configured to be urged by the first elastic member to engage with the plurality of first engaged portions,
- a second engaging portion movable in a vertical direction and configured to engage with the plurality of second engaged portions,
- a second elastic member configured to urge the second engaging portion downward, and
- an urging portion provided at the lever and configured to urge the second engaging portion upward against the second elastic member,
- wherein, as seen from an axial direction intersecting the moving direction of the regulating device in a state in which the second engaging portion engages with a second engaged portion, the urging portion is disposed between a first surface of the lever and a second surface of the lever opposite to first surface with respect to the moving direction, and the urging portion is disposed completely above the first elastic member, and
- wherein an upper end of the second elastic member is disposed above an upper end of the first elastic member.
An image forming apparatus comprising:
- an image formation unit configured to form an image on a sheet;
- a sheet stacking plate on which sheets are to be stacked;
- a cassette main body configured to support the sheet stacking plate;
- a regulating device disposed at the cassette main body to be movable in a first direction and movable in a second direction opposite to the first direction, and configured to regulate an end position of the sheets;
- a plurality of first engaged portions disposed at the cassette main body in a moving direction in which the regulating device is configured to move;
- and
- a plurality of second engaged portions disposed at the cassette main body in the moving direction of the regulating device, wherein the plurality of second engaged portions are arranged at positions separated from the plurality of first engaged portions with respect to a direction intersecting the moving direction of the regulating device,
- wherein the regulating device includes:
- a holding member,
- a lever disposed rotatably at the holding member and configured to be operated,
- a first elastic member,
- a first engaging portion configured to be urged by the first elastic member to engage with the plurality of first engaged portions,
- a second engaging portion movable in a vertical direction and configured to engage with the plurality of second engaged portions,
- a second elastic member configured to urge the second engaging portion downward, and
- an urging portion provided at the lever and configured to urge the second engaging portion upward against the second elastic member,
- wherein, as seen from an axial direction intersecting the moving direction of the regulating device in a state in which the second engaging portion engages with a second engaged portion, the urging portion is disposed between a first surface of the lever and a second surface of the lever opposite to first surface with respect to the moving direction, and the urging portion is disposed completely above the first elastic member, and
- wherein an upper end of the second elastic member is disposed above an upper end of the first elastic member.
A sheet feeding apparatus comprising:
- a sheet stacking plate on which sheets are to be stacked;
- a cassette main body configured to support the sheet stacking plate;
- a regulating device disposed at the cassette main body to be movable in a first direction and movable in a second direction opposite to the first direction, and configured to regulate an end position of the sheets;
- a plurality of first engaged portions disposed at the cassette main body in a moving direction in which the regulating device is configured to move;
- and
- a plurality of second engaged portions disposed at the cassette main body in the moving direction of the regulating device, wherein the plurality of second engaged portions are arranged at positions separated from the plurality of first engaged portions with respect to a direction intersecting the moving direction of the regulating device,
- wherein the regulating device includes:
- a holding member,
- a lever disposed rotatably at the holding member and configured to be operated,
- a first elastic member,
- a first engaging portion configured to be urged by the first elastic member to engage with the plurality of first engaged portions,
- a second engaging portion movable in a vertical direction and configured to engage with the plurality of second engaged portions,
- a second elastic member configured to urge the second engaging portion downward, and
- an urging portion provided at the lever and configured to urge the second engaging portion upward against the second elastic member,
- wherein, as seen from an axial direction intersecting the moving direction of the regulating device in a state in which the first engaging portion engages with a first engaged portion, the urging portion is disposed between a rotation range of the lever, and the urging portion is disposed completely above the first elastic member, and
- wherein an upper end of the second elastic member is disposed above an upper end of the first elastic member.
