Stapler

A binding device comprising:

• a plurality of staplers, each of the staplers including:
• a driver configured to drive a staple into a sheet, the staple having a crown and a pair of legs;
• a clincher configured to bend the legs driven into and penetrating the sheet;
• and
• a support portion configured to support the driver such that the driver is movable in a driving-in direction of the staple,
• wherein the support portion includes an attachment part,
• wherein the attachment part is configured to pivotably support the driver relative to the support portion such that the driver is rotatable about a rotational axis that is relative to the support portion, the rotational axis being perpendicular to the driving-in direction of the staple and, with the staple set in a driving-in position, perpendicular to an axial direction of the crown,
• wherein the attachment part of the support portion is configured to pivotably support a center position of the driver in the axial direction, and
• wherein the support portion further includes:
• a driver attachment portion as the attachment part, the driver attachment portion being configured to pivotably support the driver;
• and
• a driver shaft extending along the axial direction and configured to move the driver attachment portion in the driving-in direction;
• and a single operating component configured to operate the plurality of the staplers, wherein the driver shaft of the plurality of staplers is a single driver shaft passing through each of the driver attachment portions of the plurality of staplers.
