Abstract
An accordion folding mechanism folds a sheet fed from an image forming apparatus in an accordion shape by repeating a mountain fold and a valley fold in a direction perpendicular to a sheet conveying direction. A size setting unit sets a folding size of the mountain fold and the valley fold. A size adjusting unit compares a size of the sheet fed from the image forming apparatus with the folding size, and adjusts the folding size of a predetermined number of folds at a trailing end of the sheet.

A paper folding apparatus comprising:
- an accordion folding mechanism that folds a sheet fed from an image forming apparatus in an accordion shape by repeating a mountain fold and a valley fold in a direction perpendicular to a sheet conveying direction;
- a size setting unit that sets a folding size of the mountain fold and the valley fold;
- and
- a size adjusting unit that compares a size of the sheet fed from the image forming apparatus with the folding size, and adjusts the folding size of a predetermined number of folds at a trailing end of the sheet.

A paper folding apparatus comprising:
- an accordion folding mechanism that folds a sheet fed from an image forming apparatus in an accordion shape by repeating a mountain fold and a valley fold in a direction perpendicular to a sheet conveying direction;
- a mountain-fold/valley-fold setting unit that sets either one of the mountain fold and the valley fold for a first fold;
- a size setting unit that sets a folding size of the mountain fold and the valley fold;
- and
- a size adjusting unit that compares the sheet size with the folding size, calculates number of folds for folding the sheet size with the folding size and a folding width of a last fold, when the mountain fold is set by the mountain-fold/valley-fold setting unit and when the number of folds is an odd number, changes the odd number to an even number, when the valley fold is set by the mountain-fold/valley-fold setting unit and when the number of folds is an even number, changes the even number to an odd number, and adjusts the folding size of a predetermined number of folds at a trailing end of the sheet, so that a width of the last fold becomes equal to or larger than a predetermined minimum folding width and equal to or smaller than the folding size.
