Title: Paper feeding device
Inventor: HIRAOKA SHINICHIRO
IPC: B65H1/26
Filed: 1990-11-28
Abstract: PURPOSE:To perform the make-up feed of numerous sheets smoothly into a specified position without bringing the uppermost sheet into contact with a paper feed roller by covering the paper feeding direction upstream side of the paper feed roller lower part with a cover member at the time of lowering a hopper in the direction of being separated from the paper feed roller. CONSTITUTION:When a hopper 12 is pushed down at the time of refilling sheets, a separating claw 25 descends together with the hopper 12. At this time, a cover member 28 positioned on the upstream side of the paper feeding direction of a paper feed roller 16 is lowered into a specified position, so that the paper feeding direction upstream side in the lower part of the paper feed roller 16 is covered with this cover member 28. A large number of sheets are then inserted in the paper feeding direction so as to be positioned in a gap between the paper feed roller 16 and the hopper 12. At this time, the uppermost sheet is guided by the cover member 28 in such a way as not to come in contact with the paper feed roller 16, and thus the sheets are make-up fed into the specified position.

Abstract: PURPOSE:To stabilize carrying motion for recording charts by setting the carrying speed of a feeder which feeds and delivers the recording charts to the belt surface of an endless belt carrying means, to be faster than the carrying speed of the endless carrying means. CONSTITUTION:A recording chart which is fed by a feed section 303 so as to be delivered out of register rollers 415 and 416, is rested on a carrying belt 101 which has an insulating layer on the recording chart resting side, and has an inductive layer at the opposite side, just in front of a conductive roller 107 so as to be recorded by a record head section 305 while being closely adhered. In this case, if the speed of the carrying belt 101 is varied excessively, particularly when the speed of the carrying belt 101 is higher than the carrying speed of paired register rollers 415 and 416, slippage in color and the like are caused, the carrying speed of the carrying belt 101 is thereby set to be slow so that the difference in carrying speed between the belt and the paired register roller 415 and 416 is absorbed by the loop between guides 417 and 418. By this constitution, an image can thereby be printed satisfactorily.
