まりのリカバリー制御方法に係るものである。Detailed Description of the Invention (Technical Field) The present invention includes a circulating automatic document feeder that circulates a copy document placed on a document table and sends it to the exposure section of a copying machine a set number of times. A recycle mode in which one copy is made from each page and repeated for the set number of copies, and the front copy paper is stored in the intermediate tray, and then the paper is fed from the intermediate tray to make a copy on the back side and output to the output tray. The present invention relates to a method of controlling a copying machine having a duplex mode function, and particularly to a method of controlling recovery from a paper jam.

時間の増大を余儀なくされていた。(Prior Art) In the above-mentioned type of copying machine, conventionally, when a jam occurs while copying the back side by feeding paper from the intermediate tray, the paper is stored in the intermediate tray except for the paper that has been completely ejected to the output tray. All copies, including the original ones, are ejected from the machine and are considered useless copies. Therefore, the number of unnecessary copies and the ejection time from the machine are unavoidably increased.

こで本発明の具体例を以下に記述する（第２図参照）。In such a copying machine 100 and RDF 200, there is a one-sided/double-sided mode in which an image on one side of a copy original is formed on one sheet of copy paper, and an image on one side of two copies of an original is formed on both sides of one copy paper. One-sided mode to form two-sided mode, two-sided mode to form images on both sides of the copied original on two copy sheets, and two-sided mode to form images on both sides of the copied original on both sides of one sheet of copy paper. Two-sided mode, an automatic document feed mode (ADF mode) in which copies are made from each of multiple originals for the set number of copies, and a recycling mode in which one copy is made from each of multiple originals and this is repeated for the number of set copies. A combination of multiple operations is possible. Here, a specific example of the present invention will be described below (see FIG. 2).

The third sheet is being transported. FIG. 2(b) shows a state in which all the set copies have been stored in the intermediate tray 133 and the back side copying is about to start. Figure 2 (
In C), reverse side copying is started by paper feeding from the intermediate tray 133, the second sheet of the first set is completely ejected to the output tray 122, the third sheet of the first set, and the first sheet of the second set are ejected. During transportation,
The second and subsequent sheets of the second set are still in the intermediate tray.
今、第２図（Ｃ）の状態でジャム発生と仮定し、リカバ

１）排出完了しているＩｖＬ目の２枚目までは使用可で
ある。1) Up to the second IvL sheet that has been discharged can be used.
２）搬送パス上にある１Ｍ１目の３枚目、２組目の１枚
目は使用不可のため、機外に排出、する。2) The third sheet of the first set of 1M and the first sheet of the second set on the conveyance path cannot be used, so they are discharged outside the machine.
３）中間トレイの中にある２紐目の２枚目を機外に排出
する。3) Eject the second sheet of the second string in the intermediate tray to the outside of the machine.
４）上記する様に、１組目の３枚目〜２組目の２枚目を
使用不可として機外に排出するため、不足部数１組分を
表面リカバリーコピーして中間トレイに収納する。4) As described above, in order to discharge the third sheet of the first set to the second sheet of the second set as unusable and discharge them from the machine, the missing set of copies is subjected to surface recovery copying and stored in the intermediate tray.
５）以後、中間トレイからの給紙で２ＭＬ目の３枚目を
１組目の３枚目とみなして第３図で示す表の様な置き替
えにてコピー動作を続行する。5) Thereafter, the third sheet of the 2ML is fed from the intermediate tray and is regarded as the third sheet of the first set, and the copying operation is continued with replacement as shown in the table shown in FIG.

施させることになる。Note that in the present invention, it is assumed that there is one set or less of transfer paper on the conveyance path from the completion of paper feeding to the intermediate tray to the completion of ejection to the output tray, but in the case where the conveyance path is long and there are two or more sets of transfer paper. There is also. In this case, exactly the number of sheets that can be separated by the number of copies will be ejected from the machine, and two or more sets of glue recovery copies will be performed.

In a copying machine that has a recycling mode that repeats for the number of copies, and a duplex mode that copies the copy paper on the front side, stores it in the intermediate tray, feeds it from the intermediate tray, copies it on the back side, and outputs it to the output tray. If the machine is in duplex mode and a malfunction occurs due to paper jam etc. while copying the back side from the intermediate tray, the copy paper that has been fed from the intermediate tray and has not yet been ejected to the output tray and this copy paper. One set of copy paper including the number of sheets is ejected from the intermediate tray to the outside of the machine, and with this ejection, one set of missing back side copies is made a recovery copy, stored in the intermediate tray, and then back side copying is resumed.
