A book binding device binding a bunch of sheets fed from a sheet aligning unit includes a sheet aligning plate aligning a section of the bunch of sheets fed from the sheet aligning unit; a gripper fixing the bunch of sheets aligned by the sheet aligning plate; an adhesive unit feeding an adhesive member to the section of the bunch of sheets to bind the bunch of sheets; and a milling unit milling the section of the bunch of sheets before the bunch of sheets is subjected to binding by the adhesive unit.
1. A book binding device binding a bunch of sheets fed from a sheet aligning unit, the book binding device comprising:
a sheet aligning plate aligning a section of the bunch of sheets fed from the sheet aligning unit;
a gripper fixing the bunch of sheets aligned by the sheet aligning plate;
an adhesive unit feeding an adhesive member to the section of the bunch of sheets to bind the bunch of sheets; and
a milling unit milling the section of the bunch of sheets before the bunch of sheets is subjected to binding by the adhesive unit,
wherein the milling unit includes:
a cutting tool cutting the section of the bunch of sheets;
a cutting tool moving rod moving the cutting tool along the section of the bunch of sheets;
a driving motor rotating the cutting tool; and
an earth powder tub under the cutting tool.
2. The book binding device as claimed in claim 1 , wherein the earth powder tub is provided with an earth powder suction fan.
