ことが必要である。When double-sided copying or double-sided printing is performed using a copying machine or printing machine, the paper that has been copied or printed on one side is turned over and re-feeded. To avoid inconveniences such as misalignment in the front, back, left, and right positions, the paper that has been single-sided copied or printed and is discharged one by one into the □ tray should be aligned with the leading edge and the reference side edge at the specified position. It is necessary to stack them on the tray in perfect alignment.

りジャムを生ずる等の欠点があった。Conventionally, for this purpose, a front abutment plate and a reference side wall are provided on the front edge and one side of the tray that receives the paper to be ejected, and the paper is ejected onto the tray. It is known that the paper is conveyed diagonally so that the front edge and reference side edges of the paper follow these reference surfaces and are aligned; however, in this case, the paper is skewed (paper direction is tilted with respect to the transport direction)
If the paper is ejected with the reference side edge shifted outward, the leading edge of the paper may hit the rear end of the reference side wall, causing the paper to rotate or jam.

ング等の手段により適当な値を得ることも可能である。The inclined roller 11 is provided near a corner of the front end of the double-sided tray 5 on the side where the reference side wall 10 is provided, and is inclined at an angle θ toward the reference side wall 10 with respect to the paper traveling direction. The inclined roller 11 is pivotally supported on the free end of the inclined roller arm] 3 which is rotatably supported around the drive shaft 12.
While the paper is being discharged to the double-sided tray 5, it is continuously driven to rotate in the direction of the arrow shown in FIG. The tilted roller arm 13 is in the raised position where the tip is flipped up, and the roller 1 at the tip is lifted up by its own weight.
1 is movable between a lowered position and a lowered position where it can follow the upper surface of the paper. Further, the inclined roller 11 is connected to the inclined roller arm 13.
At the lowered position, as shown in Fig. 1, the uppermost sheet 1 in the tray 5 rotates while being pressed against the upper surface of the uppermost sheet 1 with an appropriate pressing force due to its own weight, so that only the uppermost sheet 1 is moved in the paper ejection direction. The sheet 1 is conveyed in an oblique direction with an angle of 0, and the front edge of the sheet 1 hits the front abutment plate 9 and the side edge hits the reference side wall 10, and the sheet 1 is continuously fed in a perfect pattern, and then it slips and jams occur in the sheet. The feed force is set to such a level that it does not occur. This feeding force is caused by the frictional force between the circumferential surface of the roller 11 and the paper l, which is determined by the weight of the inclined roller 11 and the material of the inclined roller, and by making this frictional force larger than the frictional force between the sheets. Newly ejected sheets can be aligned without disturbing the stack of sheets that have already been aligned with the reference. According to the experimental results, sponge rubber was the most suitable material for the rollers 11. Note that the contact pressure between the rollers 11 and the paper 1 described above is determined not only by the weight of the rollers 11 described above, but also by means such as a spring.

用紙の上面を分離給送コロ７に押圧する。The above-mentioned lateral movement of the duplex tray 5, lifting and lowering of the tray pressurizing arm 6, and lifting and lowering of the inclined roller arm are performed by a half-rotation clutch that is controlled by selecting the duplex copying mode and turning on and off a solenoid according to a paper refeed command. The cam is sequentially controlled via a link mechanism as described below. That is, when the duplex mode is selected, the tray pressurizing arm 6 first descends to release the pressurization of the duplex tray 5.
The double-sided tray 5 is then laterally moved upwards in FIG. 3 by a distance 18aII, and then the inclined roller arm 13 is lowered. Also, when a command is given to refeed paper from the duplex tray,
First, the inclined roller arm 13 rises, then the double-sided tray 5 moves laterally by a distance of 11 aHg, the reference side wall 10 is held at a position that matches the paper passing reference, and then the pressure arm 6
rises, pushes up the double-sided tray 5, and presses the upper surface of the paper placed thereon against the separating and feeding roller 7.
