The high-speed copying apparatus as described above includes the document feeding apparatus, the image forming apparatus, a plurality of paper feed trays containing a large number of sheets, and a plurality of paper feed trays.
In order to obtain a copy speed of 70 sheets / minute or more, the plurality of sorters are internally fed with a plurality of originals or sheets as described above and maintain the copy speed. Such high-speed copying can be performed in a very short time even when processing a large number of originals and recording sheets, and has high utility value. However, as described above, in high-speed copying of 70 sheets / minute or more, the feeding and conveying speeds of originals and sheets are high, and defective feeding (hereinafter referred to as jam) is likely to occur. However, even if the above-mentioned sham occurs at one place in the feeding unit, the operation of the entire apparatus stops at the same time as the jam occurs. However, since a plurality of originals and sheets are always fed and conveyed in the machine as described above, the fact that a jam has occurred at a plurality of places is simultaneously displayed on the plurality of lamps or the like. In such a case, according to the display of the lamp, the operation of sequentially removing the original or the sheet from the inside of the machine is performed. In carrying out such an operation, a front mounting method has become mainstream in recent years so that the sheet can be easily mounted in the machine. Therefore, the sheet feeding tray and the sheet feeding cassette are pulled out in a direction perpendicular to the sheet feeding direction. It will be. By such an operation, the sheet is forcibly pulled out from the end surface of the jammed sheet during feeding, and the sheet is damaged by the pulling operation when pulling out the sheet feeding tray, which makes it difficult to remove the sheet. There is. In such a case, for example, there is also a method of smoothly removing the sheet by a separately provided sheet removing means, but conventionally, the jam location generated at a plurality of locations is merely displayed by the jam display lamp, and thus the plurality of locations can be used. It was extremely difficult to determine the means for removing the sheet at the jammed position in order without damaging it.

The present invention has been specifically devised to eliminate the above-mentioned drawbacks. As described above, when a plurality of jams occur in the apparatus, a recording paper which is jammed by a lamp or other message means is treated. The purpose is to display the priority order by the method so that the jam sheet can be removed smoothly.
