Claims (1)

[Scope of utility model registration request] In a paper sheet binding device that binds paper sheets by wrapping a tape around the area other than the clamping part of the paper sheets that are clamped at the binding position, cutting the ends of the tape, and thermally bonding the paper sheets, the paper sheets that are clamped at the binding position are a tape winding means for wrapping the tape around the outer periphery of the paper sheet other than the clamping part; a clamp means for tightening the vicinity of the tape wrapping part of the paper sheet after the tape has been wound; and a tape tensioning means for applying tension to the tape. The clamping means has first and second clamp members that tighten the paper sheets by contacting both the front and back sides of the paper sheets to be bound, and each clamp member is attached to the tape-wrapped portion of the paper sheets. One clamp member has a pair of abutting edges located on both sides in the width direction, and one of the clamp members has a tape guide section that regulates both edges in the width direction in the tape winding direction and guides the tape to a certain position. A paper sheet binding device characterized in that the clamp member is advanced and moved to a position where it comes into contact with a tape wrapped around the paper sheets prior to movement when tightening the paper sheets.
