Abstract
A sheet transport device includes a loading unit at which a sheet to be conveyed is loaded, a transport unit configured to impart to the sheet loaded at a sheet loading surface of the loading unit a transport force for transporting the sheet toward an alignment unit, and an adjustment unit configured to adjust the transport force. The adjustment unit includes a movable loading unit formed so that at least part of the sheet loading surface is configured to protrude toward the transport unit and a driving unit configured to displace the movable loading unit in a protruding direction and a retracting direction.
Claims14
A sheet transport device comprising:
- a loading unit at which a sheet to be conveyed is loaded;
- a transport unit configured to impart to the sheet loaded at a sheet loading surface of the loading unit a transport force for transporting the sheet toward an alignment unit;
- and
- an adjustment unit configured to adjust the transport force, wherein
- the adjustment unit includes
- a movable loading unit formed so that at least part of the sheet loading surface is configured to protrude toward the transport unit and
- a driving unit configured to displace the movable loading unit in a protruding direction and a retracting direction.
A method of controlling a sheet transport device, the sheet transport device including:
- a loading unit at which a sheet to be conveyed is loaded,
- a transport unit configured to impart to the sheet loaded at a sheet loading surface of the loading unit a transport force for transporting the sheet toward an alignment unit,
- an adjustment unit configured to adjust the transport force, and
- a loading number counting unit configured to count the number of the sheet loaded at the loading unit, the adjustment unit including:
- a movable loading unit formed so that at least part of the sheet loading surface is configured to protrude toward the transport unit and
- a driving unit configured to displace the movable loading unit in a protruding direction and a retracting direction, the method comprising:
- adjusting an amount of displacement of the movable loading unit based on the number of the loaded sheet.
A method of controlling a sheet transport device, the sheet transport device including:
- a loading unit at which a sheet to be conveyed is loaded,
- a transport unit configured to impart to the sheet loaded at a sheet loading surface of the loading unit a transport force for transporting the sheet toward an alignment unit,
- an adjustment unit configured to adjust the transport force, and
- a counting unit configured to count the cumulative number of the sheet transported by the transport unit, the adjustment unit including:
- a movable loading unit formed so that at least part of the sheet loading surface is configured to protrude toward the transport unit and
- a driving unit configured to displace the movable loading unit in a protruding direction and a retracting direction, the method comprising:
- adjusting an amount of displacement of the movable loading unit based on the cumulative number of the sheet.
