ABSTRACT:
Conveyor rollers 1a, 1b which are driven by a rotary drive motor 9 are disposed in different locations in a direction in which a sheet is conveyed. The conveyor rollers 1a, 1b are arranged so as to be able to move in a direction intersecting the direction of conveyance by means of sheet shift means which are driven by shift motors 11a, 11b. Sheet sensors 13a, 13b are provided in the reference position for the side edge of the sheet. If the sheet sensor 13a (or 13b) does not detect the side edge of the sheet 2, the shift motors 11a, 11b are controlled in such a way that a conveyor roller 1a (or 1b) corresponding to the sheet sensor approaches the sheet side edge reference position. In contrast, if the sheet sensor detects the side edge of the sheet 2, the shift motors are controlled in such a way that the conveyor roller departs from the reference position.
