PROBLEM TO BE SOLVED: To provide a motor rotation control means which can quickly and precisely control the rotational speed and the rotational phase of a scanner motor at a low cost, and imaging equipment provided with the motor rotation control means. SOLUTION: To a reference synchronization signal (REF signal) 150 and a speed objective value signal 139B, phase difference information obtained by clock count from a motor rotation synchronization signal (BDN signal) 113 is subjected to multiplication and division by integer power of 2, and fed back to the same control interface as the speed difference quantity by reducing the gain, thereby raising the scanner motor 147 quickly and controlling it precisely. |
