す再給紙手段とを有するものは、既に提案されている。In this type of copying apparatus, there is a paper feeding means that feeds sheets one by one to the stacked sheets 1, an image forming means including the stages of forming, developing and transferring an electrostatic latent image, and an image formed by this image forming means. A fixing means for the images on the sheets 1 to 1, which completes the copying, and a paper ejecting means for the sheets 1 to complete the copying, and a refeeding unit that receives the sheet that passes through the fixing means and sends this sheet again to the image forming means for double-sided copying. Those having means have already been proposed.

定着ローラ対１５に達する。In Figure 1, the paper feed section 1 that feeds sheets one by one is 3
There are three paper feed trays 2, 3 and 4, and each paper feed tray is adapted to store sheets 1 to 1 of different sizes in a stacked manner. Further, each paper carrier is provided with a pick-up roller 2 a p 3 a v 4 a for sending out the second-most sheet and a pair of separation rollers 2 b, 3 b, and 4 b, respectively. The lower roller of the pair of separation rollers rotates slowly in the opposite direction to the sheet feeding direction, thereby preventing double-sheet feeding that occurs accidentally due to the feeding row. The sheet 1 from each paper feed tray then reaches the paper feed path 5, passes through the pair of feed rollers 6, 7.8 arranged here, and reaches the buffer part 9, and the lateral position is corrected by the diagonal roller 1o. and reaches the register 1-roller pair 11. Next, the sheet 1- is transferred to the transfer device J in synchronization with the powder image formed on the photoreceptor drum 12.
The powder image on the photoreceptor drum 12 is transferred to this sheet, and then a separation bell]・1
4, the sheet 1- is separated from the photosensitive drum and reaches the fixing roller pair 15.

次の通りである。The device 29 for conveying the belt 1 comprises a belt 30 and rollers 31 cooperating therewith, and a third switching guide plate 32 is provided at the end of the conveyance. When this third switching guide plate is in the position shown by the solid line, the conveyor belt 1 to the device 29 is connected to the sea 1.
When the third switching guide 4) j32 is at the position shown by the broken line, the sheet is guided by the third switching guide 4) and stored on the intermediate □1-lay 34. A pair of rollers 35 for refeeding the paper are provided between the intermediate 1 and the lay 34.
are set up opposite each other. Reference numeral 36 denotes a presser for the sheets stacked on the intermediate tray 34, and this presser prevents the sheets that can be copied on one side from lifting up, thereby making it possible to efficiently refeed the sheets. Reference numeral 37 denotes a pair of delivery rollers for the seas 1 to 1 sent out by the pair of rollers 35.
(The operation mode regarding sheet path switching of the copying apparatus according to the present invention described above is as follows.
It is as follows.

When the 1,7I exchange guide plate 25 is at the broken line position, for example, a sheet to be copied on one side reaches the reversal guide section 21,
At this point, the main roller 19 and the post-reversal roller 20 are reversed.
and then reaches the paper discharge tray 28. At this time, the images of the discharged sheets 1 to 1-ray are facing downward,
Therefore, they are arranged in page order.
