<P>PROBLEM TO BE SOLVED: To solve such a problem that it is difficult to achieve a stable operation by suppressing speed variation for a specific control object. <P>SOLUTION: The printer includes a motor which drives the control object; and a control part which detects a speed of the control object, computes a first control amount to the motor on the basis of a difference between the detected speed and a target speed of the control object, and can carry out feedback control to drive the motor on the basis of the first control amount. The control part includes a second control amount determining part which obtains a speed variation amount of the specific control object in a predetermined period wherein the specific control object is operated by driving the motor through feedback control (S110) and which determines a second control amount to the motor on the basis of the speed variation amount (S120), and a specific control part which drives the motor on the basis of the first control amount and the determined second control amount in a specific section of the operation when the specific control object is operated by driving the motor through feedback control. <P>COPYRIGHT: (C)2011,JPO&INPIT |
