PURPOSE:To enable blanks having different thicknesses to be securely supplied by providing vertically pivotably a paper supply roll bracket above a blank tray and rotatably a paper supply roll on this bracket while providing a weight movably. CONSTITUTION:A drive shaft 2 is rotatably supported above a blank tray 1 to support vertically pivotably a pair of paper supply brackets 3. Said drive shaft 2 is inserted into holes 4 provided in one ends of longitudinal plates 3b at both sides of said respective brackets 3 and a paper supply roll 5 is similarly rotatably inserted between the other ends. Also, lateral plates 3a of the respective brackets 3 are formed with guide grooves 10 in the logitudinal direction into which is fitted slidably a guide piece of a weight 11. And a down ward pivotal force of said each bracket 3 is adjusted by sliding this weight 11 along the guide groove 10 to adjust the contact pressure of the paper supply roll 5 against the blank. |
