A stepping motor drive circuit includes a control-purpose controller, the control-purpose controller having: 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 configured 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 is configured to switch operations of stator coils provided in the stepping motor pursuant to the command information, to rotate the stepping motor to the rotating position included in the command information and to 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.
