ABSTRACT:
The present invention propose a driving apparatus for an image processing system. A DC motor with a feedback controlling system is utilized as the driving apparatus. With the design of the present invention, the accuracy of the position control can be increased and the prior art problem of missing steps and unequalled steps can be eliminated. The driving apparatus of the present invention includes a DC motor, a position detecting device, an error counter, a controlling circuit, and a driving circuit. The position detecting device is employed for detecting positions of the DC motor in order to generate feedback signals. The error counter is responsive to input signals and the feedback signals for generating error signals. The controlling circuit is responsive to the error signals for controlling the DC motor. The driving circuit is responsive to the controlling circuit for driving the DC motor.
