First, in the case of the recycle ADF mode, as shown in FIG. The documents are fed one by one, and the surface of the document is scanned and illuminated by scanning illumination means in the copying machine 11. Then, a known exposure process is performed using the original reflected light containing image information. Next, the original sheet S is sent to the downstream side by the transport unit 44, and the selective ejection means 2
The paper is discharged to the second tray 23 side by a pair of transport rollers 52, 0, 53 and 54. At this time, since the ejection direction switching member 55 is swung upward by the tension of the tension spring 57, the original sheets S are again stacked on the first tray 21 in the order in which they were initially stacked.

Next, in the case of the duplex mode in which the original sheet S is a double-sided original, as shown in FIG. Then, when the paper detection sensor 73 detects the leading edge of the original sheet S in the path forming member 51, the solenoid 60 is sucked, and the discharge direction switching member 55 swings downward. Therefore, the original sheet 1-S discharged from the contact glass 13 onto the second tray 23 is turned upside down by the reversing mechanism 25, and is loaded onto the first tray 21 upside down from the initial set state. , wait until the back side is copied. After copying the back side, it is stacked on the first tray 21 again (the reversing mechanism 2
5), or the switching claw 71 rotates upward and the document sheet is rotated).
S is discharged to the document discharge tray side of the copying machine 11.

On the other hand, if a jam or the like occurs on the copying machine 11 side and the recording operation fails, the controller I that received the command from the copying machine 11
- The solenoid 60 is sucked by the roller, and the ejection direction switching member 55 swings downward to an almost horizontal position, so that the original sheet S that has failed in copying (recording operation) is moved to the upper position as shown in FIG. 2 tray 23. Therefore, by rotating the guide plate 26 upward to completely open the top of the second tray 23, the document sheet S can be easily taken out, and by manually feeding it from the insertion lower 2, the jam etc. can be dealt with immediately. can.

In this way, in this embodiment, the second +-ray 23
Since the reversing mechanism 25 provided on the downstream side is connected to the first tray 21 as a document conveying means having a reversing function,
The second tray 23 has a very simple structure and also serves as a guide member for the reversing mechanism 25, making it possible to provide a small, low-cost, high-performance document conveying device. Further, since the ejection direction switching member 55 of the selective ejection means 24 is supported by the 21st tray 23 so as to be able to swing downwards, the conveyance path of the original sheet S can be simplified and the size can be further reduced. Can be done. Further, when a recording operation of the copying machine 11 fails, the second tray 23 can be opened and the original sheet 1-'S can be taken out very easily, and the re-feeding operation can be made much easier. In addition, since a notch 55a is formed in the ejection direction switching member 55, the document sheet S on the first tray 21 can also be easily taken out.

In this embodiment, the document sheet S is detected from the detection information (detection signals of the leading edge and trailing edge) of the paper detection sensor 73, etc.
It is also possible to use the first tray 21 and the second tray 23 differently and stack them for each size by having the controller know the size of the tray.

According to the present invention, the selective ejection means selectively ejects the original sheets 1 to either the first or second tray, and
Since the reversing mechanism 3 provided on the downstream side of the second tray is connected to the first tray as a means of conveying documents, the second tray has a very simple structure and also serves as a guide member for the reversing mechanism. It is possible to provide a small, low-cost, high-performance document transport device.
