STACK ROLLER AND MEDIUM STACKING APPARATUS HAVING THE SAME

摘要

PURPOSE: A stack roller and a medium-integrated device thereof are provided to stable transfer a medium by improving the strength of a stack sheet and bending the medium touching the stack sheet. CONSTITUTION: A stack roller includes a roller body (10) and a stack sheet (11). The roller body is inserted into a rotation shaft of a medium-integrated device. A plurality of stack sheets are placed on the roller body in a radial type. The stack sheets hit a rear end of a medium during the integration of the medium, touch a side of the medium during while the medium is passing, and hit the rear end of the medium during the entry of the medium. The stack sheets are placed near by the roller body in order to improve the strength of the medium by bending the medium. The stack sheets form a thick inside part (11a) and an outside part (11b) extended to the outside of the inside part.
