Abstract: PURPOSE:To perform a backlash correction in accordance with various types of recording mediums by a method wherein when a recording medium is fed reverse, the thickness of the recording medium is detected, and a correction amount by a backlash correction means is changed in accordance with the detected thickness. CONSTITUTION:The thickness of recording paper 38 is judged on the basis of a digital signal transmitted from an A/D converter. In accordance with the detected thickness of the recording paper 38, a backlash correction amount is determined. When the thickness of the recording paper 38 is detected, the recording paper 38 is fed reverse by the specified length, thereafter being fed forward excessively by the length in accordance with the backlash correction amount. When the recording paper 38 is fed reverse, the backlash correction amount is found in accordance with the thickness of the recording paper 38.
