ABSTRACT:
A binding device for binding a stack of sheets with a bind member in which parallel legs extend perpendicularly from a straight portion, the binding device comprises: a driver plate which drives the straight portion of the bind member toward the legs; curved shaping guide grooves which are formed to respectively correspond to the legs; and a fulcrum member which is disposed in the vicinity of and inside one end of each of the shaping guide grooves, and which constitutes shaping fulcrums, the shaping fulcrums respectively engaging with side faces of the legs of the bind member which is driven out toward the one end of each of the shaping guide grooves, thereby bendingly shaping the legs, and, during a period after the bind member is driven out and before the legs are formed into ring-like shapes by the fulcrum member and the shaping guide grooves, the legs are passed through punched holes formed in an edge portion of each of sheets.
