When feeding a document, the stopper solenoid is activated to move to the position shown by the broken line. Then, the original 8 above the paper feed stopper 11
A weight 12 is arranged facing the base end 5b of the loading table 5, and the weight 12 is normally not operated and is located at the solid line position. When the feed roller 7 is in the position shown in FIG. Furthermore, a paper feed path 13 is provided from the downstream side of the separating section 9.degree. 10 to the transport belt 3, and a reversing roller 15 is provided near the paper feed path 13. Then, from the conveyor belt 3 to the reversing roller 1
a paper ejection path 1 extending along the outer periphery of the original document stacking table 5;

is transported tR between the platen 2 and the conveyor belt 3, and is placed at a predetermined position on the platen 2 by the conveyor belt 3 so that its rear end stops at the arrow A position. The stopping accuracy of the original g4S is determined by the belt motor 32 that drives the conveyor belt 3 when a predetermined time elapses after the paper feed sensor 22 detects the trailing edge of the document and the trailing edge reaches the arrow A position.
This is guaranteed by applying the brakes.

1 is arranged to detect the thickness of the document S to be conveyed,
Determine which documents are causing problems in conveyance. That is, the separating parts 9, 1
0 to the registration roller 21 with a normal thickness. When the tip abuts against the register 1 and the roller 21, a loop is formed near the tip. Then, the thickness sensor lever 29 is suppressed by the loop and rotates about the fulcrum 30, and is detected by the thickness sensor 31, and it is determined that the thickness of the document Sl is appropriate. In addition, the extremely thick original S2 is written with calligraphy, and the register I/roller 21
As shown in FIG. does not detect the thickness sensor lever 29. Therefore, it is determined that the loop is not formed because the document poses a problem in conveyance, and conveyance of the document is stopped.

When the document stack S is set on the document stacking table 5, the necessary mode (number of copies, magnification, density, etc.) is entered from the operation panel of the copying machine M, and the start key is turned on, the document stack S is fed. It is sent from the roller 7 to the separating section 9-10. Then, the document bundle S is separated one by one from the bottom in the separating sections 9 and 10, and is conveyed to the downstream section The line is corrected, the sheet is conveyed between the platen 2 and the conveyor belt 3, and further, when passing through the downstream section The end is detected and the sheet is properly placed at a predetermined position on the platen 2 by the conveyor belt 3, which stops when a predetermined time has elapsed since the detection.

The sheet is carried out along the reversing roller 15 along the sheet discharge path 16 and guided to the reversing path 19 by the flapper 20 displaced to the position shown by the chain line. Then, the original S guided to the reversing path 19 is
The front and back sides are reversed in the reversing path 19, and the skew is corrected by the registration rollers 21 disposed in the downstream part is detected and placed at a predetermined position on the platen 2, and the first side (the back side as an original) is exposed for the first time. At this time, the skew correction of the document S and the detection of the trailing edge of the document are performed by the same registration rollers 21 and paper feed sensor 22 as in the case of conveying the one-sided document described above. Then, the original S which has been exposed to light at a predetermined position on the platen 2 is carried out again from the platen 2 to the paper ejection path 16, further cured and conveyed by the reversing roller 15, guided to the reversing path 19, and reversed. The sheet is then subjected to a skew correction process at a downstream portion X of the reversing path 19 that is common to the sheet feeding path 13, and the trailing edge is detected by the sheet feeding sensor 22, and the sheet is placed at a predetermined position on the platen 2. be done. And the original IS is on the second side (the front side as a manuscript)
is exposed and discharged from above the platen 2 to the paper ejection path 16, passes through the downstream section 16b of the paper ejection path 16, and is ejected to the top of the document stack S- on the platen 2 by the paper ejection roller 17. Be it.

が回転することにより原稿搬送の安定性を向上する。As shown in FIG. 4, the reversing roller 15 is composed of a plurality of slightly wide wide roller portions 15a and a plurality of narrow rib-like rollers 15b. It is arranged to face the conveyance rollers 23 and 25, and its outer periphery is made of a friction material 37 such as rubber, which improves the document conveyance performance and also improves the stability of document conveyance by rotating the reversing roller 15 itself. improves.

る。Furthermore, if a document jam occurs on the reversing roller 15, the opening/closing cover 27 can be moved around the fulcrum 26. The document is then rotated to release the pressure of the upper reversing section transport roller 25, but if the document is completely wrapped around the reversing roller 15, it will be difficult to process. For this reason, the reversing roller 15 can be easily rotated.
Further, the rib-shaped rollers 15b are arranged in correspondence with each document size so as to be slightly off from the edge of the document of each size.
これにより反転ローラ１５に巻き付いたかたちの原稿の
ジャムは、操作者がリブ状ローラ１５ｂをつまんで回転

、該つまみ部材３９を回転して処理してもよい。As a result, a jam of a document wrapped around the reversing roller 15 can be disposed of by the operator pinching and rotating the rib-like roller 15b. Alternatively, a gripping member 39 may be fixed to the shaft of the reversing roller 15, and when a jam occurs, the gripping member 39 may be rotated to handle the jam.

ができる。Further, in the above embodiment, the paper feed sensor 22 is provided downstream of the registration roller 21, but if the registration roller 21 and the conveyor belt 3 are driven by different systems, variations will occur due to the speed difference between the two. As shown in FIG. It may be located on the side, in which case it can also serve as a side sensor.

The feeding path and the reversing layer tttts feeding path are merged to form a common path, and the common portion is provided with a placement position defining means for specifying the placement position of the document to be conveyed to a predetermined position. The number of parts can be reduced by using a single part. Therefore, the size and cost of the entire device can be reduced.

バラツキを解消することができる。In addition, since a placement position specifying means for specifying the placement position of the original to be conveyed to a predetermined position is provided in a common part where the document conveyance path and the reversing document conveyance path merge, the placement position determination means of the same member can be used. By defining the original from the original transport path and the original from the inverted original transport path, it is possible to eliminate variations in the accuracy of feeding the original to a predetermined position.
