PROBLEM TO BE SOLVED: To control a plurality of motors being driven rotationally at different drive timings using a small volume of data. SOLUTION: The motor controller comprises a circuit Pk outputting a reference pulse at a set reference pulse frequency in order to drive stepping motors Ma, Mb and Mc at a steady rotational speed, a circuit Pt outputting a rising pulse having a frequency varying such that the rotational speed of the stepping motors Ma, Mb and Mc increases at a set rate from the stopping state to the steady rotational speed at the time of rising (starting rotation of) the stepping motors Ma, Mb and Mc, and pulse switching circuits Sa, Sb and Sc receiving pulses from the reference pulse output circuit Pk and the rising pulse output circuit Pt and outputting one of the input pulses. |
