要である。A device that automatically feeds printer VcIL slips one by one is called a sheet feeder. Conventional sheet feeders are equipped with a mechanical clutch that rotates the big roller by attracting the magnet of the clutch and feeds only one sheet of paper to the rear of the platen.The power is generated by the pick roller that rotates the platen as it is. Although it has a mechanical clutch, the mechanical VC is complicated. Some also use motors for power, but the motors need to be controlled.

送り出し。The sheet feeder of the present invention uses a one-way clutch, Sumire Kaneuchi, and utilizes the forward and reverse rotation of the platen power as a drive source, thereby eliminating the need for conventional mechanical clutches.
It provides a simplification of the mechanically complicated VC41 movement system such as the motor. That is, in the present invention, when the platen rotates in reverse, the feed system on the sheet feeder side acts to feed the paper.

いる。The structure is such that paper is sucked into the platen when the grating rotates normally.

rc, rotation is transmitted to the shaft 9 only when it is turned counterclockwise, and the pickup roller 10 sends the paper all the way to the hopper 11.0 When the pulley 8 is turned clockwise, no power is transmitted to the shaft 9Vc. When completed, platen 1
When the hopper 1 is rotated in the direction a, the rotation is transmitted to the shaft 9, and the pickup roller 10 rotates.
One sheet of No. 1 is peeled off and fed to the rear of the platen until it is inserted into the platen, and when the sensor 12 recognizes that all the sheets have been inserted, the rotation of the platen is stopped. Next, by rotating the platen (2b), the paper is sent to the printing position.At this time, even though the rear of the paper is on the pickup roller 10, the one-way clutch 7 is press-fitted between the shaft 9 and the pulley 8. Pick up roller 1
Even if 0 is turned by pulling the paper, pulley 8
No power is transmitted to the The printed paper is sent to the stacker 14 by the ejection roller 13. By repeating one or more operations, the paper in the p-hopper 11 can be sent one by one to the stacker 14VC.
