らないといった欠点があった。(Prior Art) A conventional copying machine capable of automatic double-sided copying transfers the transfer portion 4 of the photoreceptor 3 from a paper feed tray 2.2' set on one side of the machine body 1, as shown in FIG. A double-sided copy tray 6 is arranged at a suitable location in the lower part of the machine by branching the paper conveyance path that leads to the paper output tray 5 outside the machine. A conveyance path is provided, and during double-sided copying, a toner image is transferred to one side of the paper fed from the paper feed tray 2.2' by a transfer section of the photoreceptor 3;
After fixing this with a fixing device (not shown), the paper is stored in the double-sided copy tray 6, and then the paper is sent out again from the double-sided copy tray to the transfer section 4 of the photoreceptor 3 to be transferred to the remaining one side. The toner image is transferred and fixed, and the paper is ejected to a paper ejection tray 5 outside the machine. For this reason, the height of the machine body 1 is increased to accommodate the double-sided copy tray 6, and the machine is vertically thick. Since the K for inserting the paper was located in a very difficult place, when a problem occurred with the paper stored in the tray 6 and it became necessary to take out the troublesome paper, the task was very tedious. In addition, the double-sided copy tray 6 could only be used as a tray for storing paper that has been copied on one side during automatic double-sided copying, and as a tray for supplying copies of the remaining single-sided copy. In order to use it in this mode, a manual feed mechanism 7 as shown in FIG. 2 must be provided in addition to the normal paper feed tray 2.2'.

を目的としたものである。(Object of the Invention) The present invention has been made in order to eliminate the drawbacks of the conventional copying machine capable of automatic double-sided copying. It is easy to take out the paper stored in the tray, and there is no need to provide a special manual paper feed mechanism (in addition, the duplex copy tray, which was conventionally only used for duplex copying, can be used to load one sheet of paper in single-sided copy mode. The object of the present invention is to provide a copying machine capable of automatic double-sided copying that can be used as a paper feed tray.

The paper fed from the tray and subjected to single-sided copying at the photoconductor transfer section is stored in a double-sided copy tray located outside the main body of the machine, and then the paper is transferred from the tray to the photoconductor transfer section inside the machine. In addition to making copies on the remaining one side of the machine, the double-sided copy tray placed outside the machine is equipped with two conventional manual feed functions, and a special manual paper feed mechanism is provided, unlike conventional machines of this type. It was made out of necessity.

Out of the multiple sheets of paper that were successively copied during single-sided copying during double-sided copying, a problem occurred with the paper that corresponds to a certain page of the original, and the paper was ejected onto the tray 5. Removal from inside the duplex copy tray 6 (When the need arises, the duplex copy tray 6 is located outside the machine, so the operator can remove the paper outside the machine, and set the machine to single-sided copy mode. If desired, a manual feed mechanism 8 is provided in the double-sided copy tray 6 as shown in FIG. 4, and a plurality of sheets are set in the tray 6, thereby making it possible to feed the sheets continuously.
