ABSTRACT:
In a sheet feeding apparatus for transmitting the rotation of the motor shaft of a motor to a sheet feeding shaft for feeding a sheet by an elastic transmission mechanism, a speed state amount of either or both of the motor shaft and sheet shaft is compared to a position deviation signal at the input side of the motor and the resulting deviation signal therebetween is applied to the motor as a motor control signal to control it, thereby improving the dynamic characteristics of the sheet feeding.
