PURPOSE:To achieve a high precision sheet feed by providing a control means to control to output a frequency voltage to a power source means to make a frequency voltage to be applied to vibrators zero or make a sheet transfer impossible when a sheet transfer quantity information from a sheet transfer quantity detecting means reaches a predetermined transfer quantity. CONSTITUTION:When a sheet transfer quantity detecting means 8 detects that a sheet 13 reaches a predetermined transfer quantity, a controller CNT outputs a frequency voltage to a power source means to make a frequency voltage to be applied to vibrators 1-4 zero or make a sheet transfer impossible. The transfer of the sheet 13 by resilient bodies 5, 6 is stopped by this. At this time, a large braking force is given to the sheet 13 by the friction force of the resilient bodies 5, 6, thereby the sheet 13 is fed at a high precision. |
