Abstract:
1. A sheet-convey device, comprising: a sheet holder on which a first sheet having a first width is placeable at a predetermined setting position and on which a second sheet having a second width larger than the first width is placeable at the predetermined setting position; a sheet-convey member configured to convey a sheet placed on the sheet holder in a predetermined sheet-convey direction perpendicular to a widthwise direction of the sheet; a sheet-width recognizer configured to recognize a width of the sheet; wherein the sheet-width recognizer includes (a) a first sensor for sensing whether a part of the sheet is present or absent at a first position of the sheet holder and (b) a second sensor for sensing whether a part of the sheet is present or absent at a second position of the sheet holder; wherein the first position is set so as to be located on an inside of the first width in the widthwise direction in a state in which the first sheet is placed on the sheet holder, while the second position is set so as to be located on an outside of the first width in the widthwise direction in the state in which the first sheet is placed on the sheet holder and on an inside of the second width in the widthwise direction in the state in which the second sheet is placed on the sheet holder; and wherein the second position is set so as to be located on an upstream side of the first position in the sheet-convey direction.
