04 has a configuration in which the paper ejection roller 104 is rotated by the rotation of the paper feed row 2102, which is connected by a belt or the like (not shown). In this case, as 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 ejection roller 104 side. I will do it. If this high paper feed roller 102 and paper ejection rollers 104, 104 are not synchronized, the paper feed roller 102 and paper ejection roller 1
There was a drawback that the paper would sag between the 04 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.

イクラッチは以下の働きをする。Further, a one-way clutch (not shown) is provided between the paper feed roller 24 and the paper feed roller shaft 30, and the one-way clutch functions as follows.
（１）用紙を普通に給紙する時には給紙ローラ軸３０の
回転を給紙ローラ２４にそのまま伝達する。(1) When feeding paper normally, the rotation of the paper feed roller shaft 30 is directly transmitted to the paper feed roller 24.

ない。(2) When the drive of the motor 22 is stopped and printing is being performed on the printer side, paper is fed by the paper feed roller on the printer side, but at this time, the rear of the paper is in contact with the paper feed roller 24. Due to the friction between the paper and the paper feed roller U, the paper feed roller 22
4 performs forward rotation, but does not transmit this forward rotation to the paper feed roller shaft.
（３）用紙を排紙する時にはモータ２２を逆回転させ、
給紙ローラ軸３０も逆回転するがこの逆回転を給紙ロー
ラ２４には伝達しない。(3) When ejecting paper, rotate the motor 22 in the reverse direction,
Although the paper feed roller shaft 30 also rotates in reverse, this reverse rotation is not transmitted to the paper feed roller 24.

げられる（第５図ａ）。Next, the effect will be explained. At the time of paper feeding, the motor 22 rotates in the direction shown in FIG.
The paper ejection port 28 rotates in the E direction in the figure, and at the same time, due to the tension of the second belt 40, the paper ejection roller 8, relay plate 60,
The second belt 40 is pulled up in the direction H in FIG. 4 (FIG. 5a).
この時給紙ローラ軸３０もＣ方向に回動しておシワンウ
ェイクラッチ（図示せず）の働きでとの回動が給紙ロー
ラ２４に伝達される。At this time, the paper feed roller shaft 30 also rotates in the C direction, and the rotation is transmitted to the paper feed roller 24 by the action of a one-way clutch (not shown).

接点まで移送される。When the paper feed roller 124 rotates in the direction C in the figure, the stack of paper 4
The uppermost one of the four sheets is removed from the separation claw 48, and the paper is transported through the paper feed port 50 by the rotation of the paper feed roller 24 to the contact point between the paper feed row 252 and the second pinch roller 56 of the printer 20. Ru.

へ移送される。When the leading edge of the paper 14 contacts the contact point between 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), and the paper 14 is moved between the first pinch roller 254 and the paper. The paper passes between the feed row 252 and is printed by the printer 20 while being delivered to the paper output port 58.

転することはない。At this time, the motor 22 is stopped, but the paper feed roller 24 is in contact with the rear of the paper 14, and as the paper 14 is fed, the paper feed roller 24 is caused by friction with the paper 14 to
However, due to the action of a one-way clutch (not shown), even if the paper feed roller 24 rotates, the paper feed roller shaft 30 does not rotate.
即ち給紙ローラ２４は空回シを行う。That is, the paper feed roller 24 rotates idly.

2 is stopped. At this time, the motor 22 begins to rotate in the reverse direction in the direction B in the figure. This rotation causes the first belt 34, the first paper feed pulley 32, the paper feed cylinder 2f-ri 36, the second
This is transmitted to the paper ejection pulley 38 via the belt 40, and the paper ejection roller 8 rotates in the direction F in the figure. When the discharge roller 8 rotates in the direction F in the figure, the tension of the second bell 40 pulls the discharge roller 8, relay plate 60, and second belt 40 together in the direction G in FIG. . At this time, as shown in FIG. 5(b), a sheet of paper 14 is inserted between the upper surface 10 of the rib 2 and the circumferential surface 12 of the sheet ejecting roller 8, and the sheet ejecting roller 8 presses the sheet 14. While rotating, the paper 14 is fed. Paper 1
4 advances and when the trailing end of the paper 14 comes into contact with the paper ejection roller 8 (FIG. 5(C)), the paper ejection roller 8 slides toward the lower end G of the guide groove 16 due to its own weight and descends. The paper ejection roller shaft 6 is locked to the lower end of the guide groove 16 . As the paper ejection roller 8 descends, the trailing edge of the paper 14 is successfully ejected.

。即ち給紙ローラ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 ejected, the paper feed roller shaft 30 also rotates in the opposite direction, that is, in the D direction, but due to the action of the one-way clutch, the paper feed roller shaft 30 idles and the I2 paper feed roller 24 does not rotate. That is, the paper is not fed in the opposite direction by the paper feed roller 24.

はいうまでもない。Further, in this embodiment, the power from the motor is transmitted by a belt, but it goes without saying that gears or the like may also be used.
又実施例ではリゾを３対、排紙ローラを３個設ける構成
としたがその他の個数でも良いことは勿論である。Further, in the embodiment, three pairs of rollers and three paper ejection rollers are provided, but it goes without saying that other numbers may be used.

簡単にすることもできる。As described above in detail and concretely, according to the present invention, since the paper is held between the reso and the paper ejection roller, the number of parts can be reduced. Further, there is no need to synchronize the paper discharge roller and the paper feed roller as in the prior art, and the configuration of the apparatus can also be simplified.
