２ピンチローラである。Conventionally, in an automatic paper feeder (cut sheet feeder) mounted on a printer, the paper feeding operation is performed by driving the paper feeding roller by the motor of the automatic paper feeding apparatus, and the paper ejection operation is performed by the printer. It is performed by a discharge roller driven by rotation of the roller. That is, in FIG. 6, the paper feed roller 102 and the paper discharge roller 104 are connected by a belt or the like not shown, and the paper discharge roller 104 is rotated by the rotation of the paper feed roller 102. In this case, as the printing progresses, the paper is sent from the contact point between the first pinch roller 106 and the paper feed roller 102 to the paper discharge roller 104 side, but the paper discharge operation is performed while sandwiching the paper between the two paper discharge rollers 104, 104. Therefore, if the paper feed roller 102 and the paper discharge rollers 104 and 104 are not synchronized, there is a drawback that the paper sags between the paper feed roller 102 and the paper discharge rollers 104 and 104. In FIG. 6, 108 is a printer, 110 is an automatic paper feeder, 112 is a head, and 114 is a second pinch roller.

図ａ）。Next, the operation will be described. At the time of sheet feeding, the motor 22 rotates in the direction A in FIG. 4, but at this time, the sheet discharging roller 8 passes through the first belt 34, the sheet feeding first pulley 32, the sheet feeding second pulley 36, and the second belt 40. At the same time as rotating in the middle E direction, the second belt
By the tension of 40, the discharge roller 8, the relay plate 60, the second belt 40
Are united and pulled up in the direction H in FIG.
Figure a).

て、プリンタ20で印字されつつ排紙口58へ移送される。When the paper feed roller 124 rotates in the direction C in the figure, a bundle of sheets 44
One of the uppermost plates is separated from the separating claw 48, and this paper is transferred to the contact point between the paper feeding roller 52 of the printer 20 and the second pinch roller 56 through the paper feeding port 50 by the rotation of the paper feeding roller 24. When the leading edge of the paper 14 comes into contact with the contact points of the paper feed roller 52 and the second pinch roller 56, the drive of the motor 22 is stopped and the paper feed roller 52 is driven by a drive source (not shown),
Passes between the first pinch roller 54 and the paper feed roller 52, and is transferred to the paper discharge port 58 while being printed by the printer 20.

Although the paper feed roller shaft 30 rotates, the paper feed roller shaft 30 does not rotate even if the paper feed roller 24 rotates due to the action of a one-way clutch (not shown). That is, the paper feed roller 24 runs idle.

る。Next, when the trailing edge of the paper 14 reaches the contact point between the paper feed roller 52 and the first pinch roller 54, the drive of the paper feed roller 52 is stopped. At this time, the motor 22 starts to rotate in the reverse direction, and B in the figure
Begins to rotate in the direction. This rotation is transmitted to the paper discharge pulley 38 via the first belt 34, the first paper feed pulley 32, the second paper feed pulley 36, and the second belt 40, and the paper discharge roller 8 rotates in the F direction in the drawing. . When the discharge roller 8 rotates in the F direction in the figure, the second
Due to the tension of the belt 40, the paper discharge roller 8, the relay plate 60, and the second belt 40 are integrally pulled down in the G direction in FIG. At this time, as shown in FIG. 5 (b), the upper surface 10 of the rib 2 is
The paper 14 is inserted between the paper ejection roller 8 and the peripheral surface 12 of the paper ejection roller 8, and the paper ejection roller 8 rotates while pressing the paper ejection roller 8 to feed the paper 14. When the paper 14 is advanced and the rear end of the paper 14 comes into contact with the paper discharge roller 8 (FIG. 5 (c)), the paper discharge roller 8 slides in the lower end direction G of the guide groove 16 by its own weight and descends. The discharge roller shaft 6 is locked to the lower end of the groove 16. Due to the lowering of the paper discharge roller 8, the rear end of the paper 14 is successfully discharged.

紙ローラ24によって用紙の逆方向へ送りは行われない。While the paper 14 is being discharged, the paper feed roller shaft 30 also rotates in the opposite direction, that is, in the D direction.
30 is idle and the paper feed roller 24 is not rotated. That is, the paper is not fed in the reverse direction by the paper feed roller 24.
