PURPOSE:To prevent the influence of a temp. change in a DC servomotor. CONSTITUTION:In a copying machine provided with a scanner for scanning an original, the DC servomotor for driving the scanner and a control means for controlling the DC servomotor and switching the servo loop gain corresponding to the velocity diagram of the scanner, a temp. detecting means 1 for detecting the temp. of the DC servomotor and the servo loop gain rearranging means 2 for rearranging a servo loop gain at the rise time of the DC servomotor corresponding to the detected temp. by the temp. detecting means 1, are provided. |
