Claims

[Scope of utility model registration request]

In a copying machine's paper folding device that folds the leading edge of the paper to facilitate separation of the paper from the photosensitive drum, one of a pair of registration rollers that feeds the paper to the photosensitive drum in a timely manner is composed of a sponge-like elastic roller. On the other hand, a storage edge paper folding member is provided, which is normally retracted from the paper transport time, protrudes when the leading edge of the paper comes into contact with the registration roller and comes to rest, and hits the elastic roller from the top of the paper. A paper folding device for a copying machine that is characterized by uniform folding in the width direction.
