PROBLEM TO BE SOLVED: To reduce uneven rotation of a pulse motor. SOLUTION: The intervals of pulse signals P0, P1, P2, P3, P4,... formed to meet rotational speed with a preset target are corrected using a prescribed correction table to obtain pulse signals P10, P11, P12, P13, P14,.... That is, the pulse signal P11 is corrected so as to shorten the interval of the pulse signal based on a correction amount which the prescribed correction table indicates, and the pulse signal P12 is corrected so as to extend the interval of the pulse signal based on a correction amount which the prescribed correction table indicates. |
