Both side copying machine

A copying machine comprising:

• an original holder having a holding surface for simultaneously holding for exposure a first original for a first side copy and, adjacent thereto, a second original for a second side copy onto copy material;
• a photosensitive member;
• means for applying an electrostatic charge to said photosensitive member;
• an optical system for projecting images of the first and second originals onto said photosensitive member to form electrostatic latent images thereof;
• means for developing the electrostatic latent images to form respective developed images;
• means for transferring the developed images to a copy material;
• first feeding means for feeding a copy material toward and past the transferring means with a first end thereof constituting a leading end during movement thereof by said first feeding means, wherein the developed image corresponding to said first original is transferred onto a first side of a copy material;
• means for reversing the copy material fed by said first feeding means after the developed image is transferred onto a first side of the copy material, to move the copy material with its opposite end as a leading end;
• means for engaging the said opposite end of the copy material after it is reversed, to stop the copy material and to allow it to be stacked;
• and
• second feeding means for feeding the said stacked copy material to the transferring means with said opposite end thereof as the leading end wherein developed image corresponding to the second original is transferred onto the said second side of a copy material to receive the developed image corresponding to the original for the second copy.

A copying machine comprising:

• an automatic original feeder for successively transporting plural sheet originals and discharging them in a reversed state, and for then transporting them and discharging them in an original state;
• a photosensitive member;
• means for applying an electrostatic charge to said photosensitive member;
• an optical system for projecting images of said originals onto said photosensitive member to form electrostatic latent images thereof;
• means for developing the electrostatic latent images to form developed images;
• means for transferring the developed images to sheets of copy material;
• first feeding means for feeding copy sheets toward and past the transferring means with a first end of each said sheet constituting a leading end during movement thereof by said first feeding means for successively transferring said developed images onto successive copy sheets;
• means for reversing the copy sheets fed by said first feeding means after developed images are transferred onto first sides thereof, and to move the copy sheets with their opposite ends as leading ends;
• means for engaging the copy sheets conveyed from said reversing means and to stack the copy sheets;
• and
• second feeding means for feeding the said stacked copy sheet in the order corresponding to the originals which are fed after discharge by said automatic feeder in the reversed state.
