Binding mechanism cartridge, binding device body and sheet processing apparatus

A binding mechanism cartridge being storable in a storage portion of a binding device body instead of a staple cartridge, the staple cartridge being storable in the storage portion of the binding device body, the binding mechanism cartridge comprising:

• a body portion having an outer width set to a size corresponding to an inner width of the storage portion and being detachably held by the storage portion;
• a lateral slide mechanism unit provided on a front surface of the body portion and being slidable to the body portion in a lateral direction, the lateral slide mechanism unit comprising:
• a base portion protruding from a lower part of a front surface of the lateral slide mechanism unit and configured to support a bundle of sheets from a bottom surface of the bundle of sheets;
• and
• an upward-and-downward moving portion attached to the front surface of the lateral slide mechanism unit and positioned on an upper side of the base portion, the upward-and-downward moving portion being movable upward and downward along the front surface of the lateral slide mechanism unit, wherein the upward-and-downward moving portion moves close to or away from the bundle of sheets supported on the base portion by moving upward and downward, the upward-and-downward moving portion comprising:
• a binding portion provided on a lower end side of the upward-and-downward moving portion and configured to bind the bundle of sheets,
• wherein the binding portion is configured to bind the bundle of sheets by being in contact with the bundle of sheets according to a downward-movement of the upward-and-downward moving portion.
