Paper-reversing apparatus for use in providing two-sided copies

A paper-reversing device comprising:

• paper-feeding and sending roller means having a plurality of rollers that rotate while being kept in contact with one another, the plurality of rollers being provided with first and second paper-feeding-side positions through which sheets of paper are fed between the rollers and first and second paper-sending-side positions through which sheets of paper are sent out from between the rollers;
• paper-feeding guide section for guiding paper to the first paper-feeding-side position;
• paper-reversing guide section having a curved section on a paper-feeding and sending end side thereof, which is, an end on the side of the paper-feeding and sending roller means, and a shift section which is one part of the curved section that starts from a mid-point of the curved section and reaches the paper-feeding and sending end, the shift section being arranged so that it can move between (1) a paper-feeding position through which the paper, discharged from the first paper-sending-side position, is fed and (2) a paper-sending position through which the paper, discharged from the paper-feeding and sending end, is guided to the second paper-feeding-side position, and that corresponds to a position at which the curved section forms a straighter shape than a shape the curved section forms when it is positioned at the paper-feeding position;
• paper-guide driving means for moving the shift section towards the paper-feeding position as well as towards the paper-sending position;
• and
• paper-holding means for holding the paper that has been fed into the paper-reversing guide section.
