Abstract

PURPOSE:To enable smooth movement of a wide variety of printing paper sheets by changing a feeding speed according to the thickness of the sheets. CONSTITUTION:When an instruction for feeding paper sheets is given, a sheet feeding control circuit 11 calculates the necessary number of steps and sets the first half thereof for an acceleration region and the second half thereof for a deceleration region. While the step number of the turning point of the regions is memorized, a step-advance pulse is given to a pulse motor driving circuit 17 to drive a pulse motor in a stepping manner and thereby to feed the printing paper sheets 7 at the sheet-feeding speed. Meanwhile, in a comparison circuit 14, time data sent thereto and limitation time data set in a speed limit setting circuit 13 by a sheet thickness signal indicating the thickness of the printing paper sheet 7 are compared with each other, and when they are coincident with each other, a coincidence signal is delivered to the sheet feeding control circuit 11.
