Paper sheet handling device and coil forming device

A paper-sheet-handling apparatus that forms a spiral coil from a wire rod having a predetermined thickness and performs a binding processing on a bundle of paper-sheets by passing the spiral coil through the plural holes perforated on the bundle of paper-sheets, the apparatus comprising:

• a coil-forming mechanism that forms the spiral coil for binding the bundle of paper-sheets from the wire rod drawn out of a wire-rod-supplying part;
• and
• a binding mechanism that performs the binding processing on the bundle of paper-sheets by the spiral coil obtained from the coil-forming mechanism,
• wherein the coil-forming mechanism contains:
• a main body part that includes a wire rod insert port and a coil discharge port;
• a wire-rod-dispatching part that dispatches the wire rod to a predetermined direction, the wire-rod-dispatching part being attached to the main body part;
• a coil-forming part that includes plural species of the sections each like an arc of a circle for setting a diameter of the coil, is rotatably attached with respect to the main body part, is driven so as to select one section like an arc of a circle from the plural species of the sections each like an arc of a circle and forms the wire rod dispatched from the wire-rod-dispatching part into the spiral coil along the selected section like the arc of the circle;
• and
• a pitch-adjusting mechanism that adjusts a pitch of the spiral coil formed by the selected section like the arc of the circle and discharged from the coil-discharging port, the pitch-adjusting mechanism being mounted near the coil discharge port of the main body part,
• wherein in the coil-forming mechanism, the wire-rod-dispatching part dispatches the wire rod having the predetermined thickness from the wire rod insert port of the main body part to the selected section like the arc of the circle so that the wire rod comes into contact with the selected section like the arc of the circle;
• and
• the pitch-adjusting mechanism adjusts a pitch of the spiral coil dispatched by the wire-rod-dispatching part, the pitch-adjusting mechanism being mounted near the coil discharge port of the main body part;
• and
• wherein in the binding mechanism, the spiral coil adjusted in its pitch is received from the coil-forming mechanism to bind the bundle of paper-sheets.

A coil-forming device comprising:

• a main body part that includes a wire rod inserts port and a coil discharge port;
• a wire-rod-dispatching part that dispatches the wire rod to a predetermined direction, the wire-rod-dispatching part being attached to the main body part;
• a coil-forming part that includes plural sections each like an arc of a circle for setting a diameter of the coil and a selection mechanism that is set so as to select one section like an arc of a circle from the plural sections each like an arc of a circle and forms the wire rod dispatched from the wire-rod-dispatching part into the spiral coil along the selected section like the arc of the circle;
• and
• a pitch-adjusting mechanism that adjusts a pitch of the spiral coil formed by the selected section like the arc of the circle and discharged from the coil-discharging port, the pitch-adjusting mechanism being mounted near the coil discharge port of the main body part,
• wherein the wire-rod-dispatching part dispatches the wire rod having the predetermined thickness from the wire rod insert port with the wire rod coming into contact with the selected section like the arc of the circle.
