摘要： A drive control system for controlling a drive motor in response to external command signals. The system comprises a first control arrangement for obtaining numerical values corresponding to amounts of successive intermittent operations of the drive motor responsive to respective external command signals, summing the obtained numerical values, and subtracting from a current sum of the numerical values a numerical value corresponding to a non-operation time period during which the drive motor is held at rest between the successive intermittent operations. The system further comprises a second control arrangement for inhibiting the operation of the drive motor responsive to the next command signal, for a length of time corresponding to the current sum after the drive motor has completed each of the intermittent operations, whereby the temperature of the drive motor is kept below an upper limit.

摘要： A paper feeding apparatus in a printer, wherein a sheet of paper placed on a rotary support member is fed by a predetermined distance through a corresponding angle of rotation of a drive motor which is energized by a drive circuit under control of a control device which applies a control signal to the drive circuit to give a predetermined angle of rotation to the drive motor and thereby effect a paper feeding cycle each time the control signal is applied. The control device includes control means for adapting the control signal so as to progressively increase the operating speed of the drive motor up to a predetermined level when the application of the control signal takes place more than a predetermined time interval after termination of the previous paper feeding cycle. When the application of the control signal takes place within the predetermined time interval, the control means adapts the control signal so as to cause the drive motor to operate at a constant speed equal to the predetermined level throughout the predetermined angle of rotation thereof.
