Abstract:
1. A sheet processing method for folding a sheet while holding the sheet between paired folding rollers, the method comprising the step of: providing a drive motor capable of making positive rotation and reverse rotation, and a lever rotated by a specified angle according to change of a rotation direction of the drive motor; when the sheet is inserted between the folding rollers, rotating the drive motor in a first direction so as to rotate the lever in one direction, and converting a rotation force of the drive motor into a low-speed rotation output in a single direction by a first gear train so as to transmit the output to the paired folding rollers, thus rotating the paired folding rollers at a low speed; and after the sheet is folded by the paired folding rollers, rotating the drive motor in a second direction so as to rotate the lever in the other direction, and converting the rotation force of the drive motor into a high-speed rotation output in a single direction by a second gear train so as to transmit the output to the paired folding rollers, thus rotating the paired folding rollers at a high speed.
