ABSTRACT:
When the setting of sheet P is completed, a lift motor is actuated to raise the sheet P at Speed A×2. When a first light-blocking plate raised in association with the rise of the sheet P is detected by a PI sensor, the lift motor reduces its rotational speed to switch its lifting speed from high Speed A×2 to Speed A which is a half of the high speed. The Speed A does not cause the lift motor to overrun.
