ABSTRACT:
This invention relates to a motor drive device for a stepping motor used for equipment such as facsimile machine, a scanner and a printer. The motor drive device changes an excitation phase of the stepping motor in response to a motor drive instruction signal sent from a control circuit of the equipment. The motor drive device includes a register for receiving and storing data about delay times and excitation ratios sent from the control circuit of the equipment. The motor drive device changes the excitation phase of the stepping motor in accordance with the data stored in the register. The motor drive device can shorten equipment design period and reduce manufacturing cost. Further, the motor drive device can improve image reading resolution and image recording qualities.
