<p>PURPOSE:To set a pressing force of a paper feeding roller against a sheet corresponding to a movement resistance of the sheet forced out from a sheet feeding table. CONSTITUTION:A holder 53 is supported rotatably around a drive shaft 52, and held at a position where the roller surface of a sheet feeder roller 51 is protruded slightly from a sheet feeding table 1 by the exciting force of a torsional spring 55. The sheet feeder roller 51 is made in contact pressingly with the drive shaft 52 by magnetic force, and a rotating force counterclockwise is transmitted from the drive shaft 52. The drive shaft 52 acts a moment corresponding to the rotating resistance of the sheet feeder roller 51, and the moment excites the sheet feeder roller 51 upward.</p> |
