摘要： PURPOSE:To feed a paper stably with a simple structure by rotating rollers by means of a pair of transmission gears with a one-way clutch and a motor to be controlled for regular and reverse rotations. CONSTITUTION:The first and the second roller 1 and 2 are respectively driven for rotation in desired directions by the use of a single motor 20 to be controlled for regular and reverse rotations. That is, the second roller 2 is alternately driven for rotation in the feeding directions of an ordinary paper or the reverse wise, and only reversely rotated when the paper is detected by a paper-detecting means, while the first roller 1 is driven for rotation constantly in the paperfeeding wise. A pair of transmission gears 26 and 27 are fitted on shafts on the side of the first roller 1 via a one-way clutch.

摘要： PURPOSE:To prevent blanks from superposed feed and permit intermittent paper supply by providing a drive shaft of controlling rollers with auxiliary rollers having diameter larger than that of said roller and small frictional force. CONSTITUTION:Auxiliary rollers 30 are rotatably provided respetively on both sides of controlling rollers 15 on a drive shaft 13, have diameter somewhat larger than that of the controlling roller 15 and surface with high coefficient of friction and are formed of material with high flexibility. Feed rollers 14 are rotated counterclockwise and the controlling rollers 1 repeat clockwise and counterclockwise rotation unless they receive output signals from a sheet detecting mechanism. Blanks 31 set to be superposed on a sheet receiving tray 25 fall up to the peripheral surface of the roller 14 and the lowermost blank 31a is fed by the roller 14 to be caught in the auxiliary rollers 30. Then, the rollers 30 slip on the drive shaft 13 to prevent the blank 31a from jumping up and the upper blanks are sent back by the roller 15 to be prevented from superposed feed.
