Claims13
A sheet stacking apparatus, comprising:
- a first stacking portion on which a sheet is stacked;
- a second stacking portion on which a sheet is stacked, the second stacking portion being movable to a first position and a second position with respect to the first stacking portion;
- an extension stacking member on which a sheet is stacked, the extension stacking member being detachably attachable to the first stacking portion or the second stacking portion;
- and
- a restricting portion configured to restrict the extension stacking member which has been attached,
- wherein an area on which the sheet is configured to be stacked in a case that the second stacking portion is located at the second position and the extension stacking member is not attached is broader than an area on which the sheet is configured to be stacked in a case that the second stacking portion is located at the first position and the extension stacking member is not attached,
- wherein an area on which the sheet is configured to be stacked in a case that the extension stacking member is attached is broader than an area on which the sheet is configured to be stacked in a case that the extension stacking member is not attached,
- wherein the restricting portion allows the extension stacking member which has been attached to be detached from the first stacking portion or the second stacking portion and also allows the extension stacking member to be attached to the first stacking portion or the second stacking portion, when the second stacking portion is located at the first position, and
- wherein the restricting portion restricts the extension stacking member which has been attached so as not to be removed from the first stacking portion or the second stacking portion, when the second stacking portion is located at the second position.
