A sheet loading unit comprising: a sheet loading portion having a sheet loading face on which a sheet to be fed to a feeding destination is loaded; a pair of cursor members movable in a width direction of the sheet orthogonal to a sheet feeding direction on the sheet loading face to restrict a position in the width direction of the sheet; and guide grooves that are provided in the sheet loading face of the sheet loading portion and extend in the width direction to guide the cursor member to move in the width direction, wherein the cursor member includes a cursor base having a cursor plane extending substantially in parallel to the sheet loading face with a difference of step with respect to the sheet loading face, a cursor rising portion that rises relative to the cursor plane and is in contact with or in proximity to an edge of a sheet in a width direction thereof to restrict a position of the sheet in the width direction, and a connecting portion that extends from the sheet loading face side to a reverse side via the guide groove at a portion in the sheet feeding direction of an inside edge in the width direction of the cursor base, wherein the inside edge of the cursor base extends linearly in the sheet feeding direction, wherein the connecting portion has a face connecting portion which connects the sheet loading face with the cursor plane smoothly, characterized in that the face connecting portion includes an upper edge that extends horizontally inward in the width direction from the cursor plane and an inclined edge that extends from the upper edge up to the guide groove in an inclined state, wherein the upper edge and the inclined edge of the face connecting portion are structured with a pair of ribs spaced in the sheet feeding direction, and wherein in the pair of the ribs, a length of an upper edge of a rib on an upstream side in the sheet feeding direction is larger than a length of an upper edge of a rib on a downstream side in the sheet feeding direction. a sheet loading portion having a sheet loading face on which a sheet to be fed to a feeding destination is loaded; a pair of cursor members movable in a width direction of the sheet orthogonal to a sheet feeding direction on the sheet loading face to restrict a position in the width direction of the sheet; and guide grooves that are provided in the sheet loading face of the sheet loading portion and extend in the width direction to guide the cursor member to move in the width direction, wherein the cursor member includes a cursor base having a cursor plane extending substantially in parallel to the sheet loading face with a difference of step with respect to the sheet loading face, a cursor rising portion that rises relative to the cursor plane and is in contact with or in proximity to an edge of a sheet in a width direction thereof to restrict a position of the sheet in the width direction, and a connecting portion that extends from the sheet loading face side to a reverse side via the guide groove at a portion in the sheet feeding direction of an inside edge in the width direction of the cursor base, wherein the inside edge of the cursor base extends linearly in the sheet feeding direction, wherein the connecting portion has a face connecting portion which connects the sheet loading face with the cursor plane smoothly, characterized in that the face connecting portion includes an upper edge that extends horizontally inward in the width direction from the cursor plane and an inclined edge that extends from the upper edge up to the guide groove in an inclined state, wherein the upper edge and the inclined edge of the face connecting portion are structured with a pair of ribs spaced in the sheet feeding direction, and wherein in the pair of the ribs, a length of an upper edge of a rib on an upstream side in the sheet feeding direction is larger than a length of an upper edge of a rib on a downstream side in the sheet feeding direction.
