摘要： A sheet supply apparatus according to the present invention has a pawl separator for separating sheets one by one by regulating the tip ends and upper surfaces of tip end portions of the sheets, which pawl separator can be retarded from a sheet regulating position when it is urged by the sheet with a predetermined force. With this arrangement, sheets having small resiliency such as plain sheets are separated one by one by successively riding over the pawl separator, and sheets having great resiliency such as post cards and envelopes urge the pawl separator to a retracted position to pass through the pawl separator and are separated one by one by of another separation.

摘要： A device for controlling the power supplied to windings of a stepping motor includes a pulse generator for splitting one step drive period of the motor into a plurality of sections, the number of sections and increasing or decreasing depending upon the drive frequency. The pulse generator, also sets the duty cycle of a pulse applied to the motor. The device also includes a stepping motor drive circuit for exciting each phase of the motor with a current determined by the duty cycle of pulse, and a duty changing device for changing the duty cycle for each of plural sections in one excitation phase of the stepping motor, wherein a current wave input into the motor can be maintained as a sinusoidal wave from low-speed rotation to high-speed rotation of the motor by changing the number of sections in excitation depending upon serial drive operations, thereby achieving motor control with less rotation inconsistencies and less noise.
