・ ”−１２に排紙積載される。Even if a plurality of sheets stacked at this time collide with the forward rotation roller 5 and the reverse rotation roller 6, the upper stage side is blocked by the reverse rotation roller 6, and only the lowest sheet is conveyed. The sheet material sent to the conveyance roller 7 is sent to the photosensitive drum 1, and the image is transferred from the photosensitive drum 1 to the sheet material by the transfer distortion device 8. Further, the image is fixed on the sheet material by the sheet conveyor belt 9 to the fixing device 10, and the sheet is discharged by the sheet discharge roller 11.
・The ejected paper is loaded on “-12.”
次に第２図によって本発明の主要部を、￥５２男する。Next, FIG. 2 shows the main part of the present invention for 52 yen.
７−トを分離するための逆転ローラ６社軸１５に固定さ
れ軸１５の一端はコイルバネ軸継手１８により本体に支
持される回転駆動軸１７に接続されて回転される。7. A reversing roller for separating the parts is fixed to a shaft 15, and one end of the shaft 15 is connected to a rotary drive shaft 17 supported by the main body by a coil spring shaft joint 18 and rotated.
又軸１５には軸保持具２１が回転自在に取り付けられ、

ラ６は下方に押しっけられるようになっている。Further, a shaft holder 21 is rotatably attached to the shaft 15,
The other end of the shaft holder 21 is rotatably supported by a shaft 20 fixed to the device. The end of the shaft holder 21 is pulled upward by a coil spring 26. Therefore, the party of reversal-
La 6 can be pushed downward.

ラ６の上下位置を調整し正転ローラ５との適正ギャップ
を得る様になっている。Further, in order to adjust the gap t (Fig. 6) between the reverse rotation roller 6 and the normal rotation roller (5 in Fig. 1), an eccentric cam 22 is fixed near the center of a shaft 19 rotatably attached to the main body of the device. This rotation moves the shaft holder 21 up and down to adjust the vertical position of the reverse rotation roller 6 and to obtain an appropriate gap with the normal rotation roller 5.
なお軸１９の一端には偏心カム２２炬回転しやすくする
だめのツマ層２４が取り付けられている。A stop layer 24 is attached to one end of the shaft 19 to facilitate rotation of the eccentric cam 22.
７−ト先端をガイドするガイド板１４の中央に開口１４
１がありその開口１４ｔより逆転ローラ６が飛び出てい
る。7- An opening 14 is provided in the center of the guide plate 14 that guides the tip of the tip.
1, and the reversing roller 6 protrudes from the opening 14t.
ガイド板１４はガイド板１４の折り曲げ部１４２が軸１
５に嵌合し他端側は折り曲げ部１４３部で軸１９ニ嵌合
して取り付けられている。The bending portion 142 of the guide plate 14 is connected to the axis 1.
5, and the other end is fitted to the shaft 19 at the bent portion 143.
そこで逆転ローラ６のギャップ調整のためツマミ２４を
回転させることにより軸保持具２１を上下動させ、逆転
ローラ６は上下に移動し同時にガイド板１４も軸１５と
共に連動して動くものである。Therefore, in order to adjust the gap between the reversing rollers 6, the shaft holder 21 is moved up and down by rotating the knob 24, and the reversing rollers 6 are moved up and down, and at the same time, the guide plate 14 is also moved in conjunction with the shaft 15.
従って、第４図に示したようにガイド１４がらの逆転ロ
ー５乙の出張りｔＡは逆転ローラ６の位置にかかわらず
常に一定となる。Therefore, as shown in FIG. 4, the protrusion tA of the reversing roller 5B from the guide 14 is always constant regardless of the position of the reversing roller 6.
また、ガイド板１４と正転ローラ５との隙間Ｂはシート
材の厚味分であるのが理想であるが、隙間Ｂが大きくな
るに従って第４図の様に逆転ローラ６表面に突き当った
シート先端は曲がり、折れ等が発生しやすくなる。Ideally, the gap B between the guide plate 14 and the forward roller 5 should be equal to the thickness of the sheet material, but as the gap B becomes larger, it may hit the surface of the reverse roller 6 as shown in Figure 4. The leading edge of the sheet is prone to bending and folding.
通常の使用するシート厚は０ 、０５ｍｍ −０、６ｍ
ｍ程度でありそのため逆転ローラも少なくとも０．２５
ｍＷ程度の調整が必要である。Normally used sheet thickness is 0.05mm -0.6m
Therefore, the reversing roller is also at least 0.25 m.
Adjustment on the order of mW is required.
Ｂの量は厚手シートの厚味に調整するのが通常でおり、

ローラ６の出張り量をあわせることが出来（突出量を少
なくできる）安定した搬送が可能となる。The amount of B is usually adjusted to suit the thickness of the thick sheet.
For example, when setting Q and 3mm, in the conventional case where the guide plate is fixed, a thin sheet is used, and in the case of fC, B is one pair of A
Since the amount of B is adjusted so that it becomes large, the amount of B is too large and the tip of the sheet turns over and bends. However, when the guide plate 14 and the reversing roller 6 are linked, By setting the thickness (always constant) when conveying a 0.05mm sheet, you only need to adjust the B amount to the optimum value for that sheet by rotating the knob 24 (Fig. 2).Also, when conveying a 0.6rILrn thick sheet If the above Bji glass is about Q, 25
A good gap can be created and stable sheet feeding can be achieved by simply adjusting the width of the sheet to 0 mm.In particular, thin sheets are weak and tend to curl up at the tip, so adjust the protrusion of the reversing roller 6. (The amount of protrusion can be reduced) and stable conveyance is possible.
この様に逆転ローラ６とガイド板１４を連動きせること

なくなり、つまりｑに対して喝の方向に進入したシート
は折れはない。従ってシートの折れ等を生じにくくする
ためには半径ｒを大きくするか隙間であるＣの値を小さ
くしなければならないからである。By interlocking the reversing roller 6 and the guide plate 14 in this manner, the diameter of the separation roller can be reduced, and the apparatus can be made more compact. That is, as shown in FIG. 5, the smaller the illustrated angle θ of the roller 6, the less folding of the leading edge of the sheet occurs.In other words, the sheet that enters in the direction opposite to q will not be folded. Therefore, in order to make the sheet less likely to fold, the radius r must be increased or the value of the gap C must be decreased.
また、逆転ローラ乙の軸にガイド板１４を支持できるた
め両者の位置関係が精度よくなる。Further, since the guide plate 14 can be supported on the shaft of the reversing roller B, the positional relationship between the two can be accurately determined.

定した搬送ができるものである。As explained above, according to the structure of the present invention, the separation roller and the sheet guide member are movable in conjunction with each other, so that the amount of protrusion of the separation roller with respect to the sheet guide member can be kept constant, and the thickness of the sheet can be kept constant. Stable transportation is possible regardless of the length of the load.
