<p><P>PROBLEM TO BE SOLVED: To reduce costs by simplifying a mechanism of a sheet material feeding device. <P>SOLUTION: The sheet material feeding device 20 includes: a downstream roller 21; an upstream roller ; an endless dielectric belt 23 laid over the rollers and 22 and driven to circulate a rotating member 52 including a projection 52b driven to rotate and vibrating the endless dielectric belt 23 up and down by bringing the projection 52b into contact with the endless dielectric belt 23; and bottom plate raising and lowering arms 31 and 32 moving up and down a bottom plate 7 on which a sheet material bundle 6 is placed. The sheet material bundle 6 is raised, the endless dielectric belt 23 sucks an uppermost sheet material 6a, and the rotating member 52 rotates to vibrate the endless dielectric belt 23 to separate the second and succeeding sheet materials 6b from the endless dielectric belt 23, thereby preventing feeding while overlapping. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
