徴とされている。2. Description of the Related Art Generally, in a double-sided copying apparatus, a double-sided tray is used in order to provide a backside copy of a transfer sheet on which front side copying has been completed. FIG. 4 shows a conventional example of this type of double-sided copying machine known from Japanese Patent Laid-Open No. 58-68763. According to this, in the case of a normal single-sided copy, after the image formed on the photoconductor 1 is transferred from the cassette 2 to the transfer paper 4 fed by the paper feed roller 3 at the transfer portion 5, the conveyance belt 6 Then, the fixing device 7 and the discharge roller 8 are discharged and discharged onto the discharge tray 9. On the other hand, in the case of double-sided copying, the transfer paper 4 which has passed through the fixing device 7 and which has been surface-copied is guided by the switching claw 10 toward the double-sided tray 11 and stored on the double-sided tray 11 with the copy side facing up. The sheet is re-fed by the conveying roller 12, and the oblique feeding section 13
After that, the sheet is fed to the portion of the sheet feeding roller 3 and is re-fed to the transfer portion 5 by the sheet feeding roller 3 to perform back side copying. It is characterized in that the double-sided tray 11 is integrated with the paper discharge tray 9 protruding to the outside of the machine and arranged vertically.

ある。However, in the case of this method, the transfer paper 4 for back side copying is moved from the state where it is stored in the double-sided tray 11 to the conveying roller 1.
2. Since the sheet is fed to the transfer section 5 through a long re-feeding conveyance path including the diagonal feeding section 13 and the sheet feeding roller 3, it takes a long time to perform a fast copy during double-sided copy back surface processing. In particular, it is remarkable when making a single copy (one-to-one mode).
Further, since the paper discharge tray 9 and the double-sided tray 11 projecting out of the machine are integrated, these tray parts have a large thickness, and the jammed paper in the double-sided tray 11 and the oblique feeding portion 13 are formed. It is difficult to remove jammed paper.
Furthermore, the transfer paper 4 on the double-sided tray 11 cannot be directly fed by the conveying roller 12, and a dedicated re-feeding device that goes through the oblique feeding portion 13 is required, which complicates the process.
In addition, the copying mode is not limited to double-sided copying,
There is a case where it is desired to perform a composite copy (multiple copy) in which an image is transferred several times on the same surface of the transfer paper 4, but such a composite copy is difficult in the case of the conventional method shown in FIG.

ことができる。When the front side copy process is completed in this way, the process moves to the back side copy. First, the pressure lever 36r is raised by a command and the bottom plate 34r is pushed up, so that the uppermost paper of the transfer paper 31 stocked in the rear cassette portion 32r comes into pressure contact with the paper feed roller 35r. Then, by rotating the paper feed roller 35r, the transfer paper 31 is re-fed to the transfer unit 25 through the second paper feed conveyance path 39 and is used for back side copying. After that, when the double-sided copying is completed by fixing by the fixing device 27, the transfer paper 31 is discharged onto the paper discharge tray 29 through the paper discharge conveyance path 30 by switching the switching claw 43. During this backside copy process,
While the transfer paper 31 is stored in the rear cassette 32r, the transfer paper 25 is immediately transferred by the short second paper feed / transport path 39.
Since the paper is fed in, the time for the first copy can be shortened.

できる。By the way, in the one-sided copy mode (one-to-one copy mode) in the double-sided copy mode, the transfer paper 31 is also stored in the rear cassette section 32r from the beginning, and the second paper feed conveyance path 39 is transferred from the rear cassette section 32r. The transfer paper is fed to the transfer section 25 to make a front side copy.
As described above, after returning 1 to the rear cassette section 32r through the reversal return conveyance path 46, the sheet can be immediately re-fed through the second paper feed conveyance path 39 for back copy. That is, the rear cassette unit 32r can function as both a paper feed cassette and a double-sided tray. According to such a single-copy process, the transfer path of the transfer paper 31 becomes shorter, so that the copy time can be shortened.

にも応ずることができる。Next, the composite copy mode will be described. Basically, it is the same as in the double-sided copy mode, but the transfer sheet 31 fed from the front cassette section 32f and copied passes through the fixing device 27 and then enters the inversion path 41 by switching the switching claws 43 and 44. Without being turned, it is turned by the return conveyance path 47 and is conveyed by the conveyance roller 45 to the rear cassette portion 32r.
It is released and stored. That is, the copy surface is stored facing down. Then, in the second copy, the transfer sheet 31 is then fed from the cassette section 32r to the transfer section 25 through the second sheet feeding / conveying path 39, and the copied surface is provided for copying again, and the composite copy is made. Is done. After that, the sheet is discharged onto the sheet discharge tray 29 through the fixing device 27 and the sheet discharge conveyance path 30. In this way, it is possible to easily meet the request for the synthetic copy.

とにより対処することもできる。Next, the normal single-sided copy mode will be described.
In this case, as in the case described above, the transfer paper 31 housed in the front cassette 32f is fed to be used for copying, and the fixing device 2
Immediately after passing through 7, the discharge tray 2 is discharged by the discharge conveyance path 30.
9 may be discharged onto the sheet 9, but the transfer sheet 31 is also stored in the rear cassette section 32r.
Therefore, the transfer paper 31 may be fed to the transfer unit 25 and used for copying. That is, the cassette 32 can be used as a double-cassette type with the cassette parts 32f and 32r, and one cassette 32 can be used as a cassette having a double capacity. Alternatively, copying can be continued by the transfer paper 31 of 32r, and it is possible to support limitless. Further, when it is desired to make a copy onto the transfer paper 49 having a size larger than the transfer paper 31, as shown in FIG. 3, the cassette 50 having the same size as the cassette 32 and not divided into the front and rear cassette parts 32f and 32r is used. Instead of 32, a replacement set can be taken.
