A stepping motor drive circuit includes a control-purpose controller including a control-purpose position detecting unit; a rotation command information inputting unit arranged to receive command information on the rotating position of the stepping motor; a control-purpose deviation calculating unit arranged to calculate a positional deviation between the rotating position of the stepping motor detected by the control-purpose position detecting unit and the rotating position included in the command information; and an amplitude value setting unit. The amplitude value setting unit switches operations of stator coils of the stepping motor pursuant to the command information, rotate the stepping motor to the rotating position included in the command information, and increase or decrease an amplitude value of a drive current fed to the stator coils during stoppage of the stepping motor depending on the positional deviation calculated by the control-purpose deviation calculating unit.
