ABSTRACT:
A recording apparatus includes a feed roller which feeds a paper sheet, a feed motor which drives the feed roller, and a loss-of-synchronism detecting unit which detects loss of synchronism of the feed motor. When loss of synchronism of the feed motor is detected by the loss-of-synchronism detecting unit, the rotational speed of the feed motor is reduced stepwise. Accordingly, it is not necessary to provide a high operational margin in the motor, and a recording apparatus, in which the motor and power supply costs are reduced, can be provided.
