<p>PURPOSE:To load a sheet in a desired position, by fitting suction-attracted sheets on a movable frame which is moved straight by a guide mechanism, and by using a crank mechanim to apply a driving force, so as to accurately attract the sheets one by one in a suctional manner. CONSTITUTION:When a start switch is turned on, a movable frame 28 is moved to a storage position in an automatic sheet loader 14. At that time, a moving bracket 62 is moved forth to bring a sheet guide pin 66 into contact with a guide pin 22 in a magazine 16, and swing arm is turned to move a suction member 88 forth to attract a sheet 18 by suctional negative pressure. After that, the swing arem is turned again so that the suction member 88 moves the sheet 18 toward the moving bracket 62. The sheet 18 on other sheets in the magazine 16 is thus pulled out from the guide pin 22 and engaged on the sheet guide pin 66. The movable frame 28 is then elevated to move the bracket 62 to a loading position to drive an operating lever to rotate a sheet winding drum 12 to a position in which the sheet 18 can be loaded thereon.</p> |
