摘要： A first determining section determines whether a recording medium is conveyed in a first direction. A setting section sets a first current value as a current initially outputted to a DC motor each time the first determining section determines that the recording medium is conveyed in the first direction. A first current outputting section outputs a current at the first current value, and subsequently outputs by steps a current gradually higher than the first current value motor until the first determining section again determines that the recording medium is conveyed in the first direction. A second determining section determines whether the recording medium is conveyed in a second direction opposite the first direction after the first current outputting section outputs a current at the first current value. A first updating section updates the first current value to a second current value higher than the first current value, when the second determining section determines that the recording medium is conveyed in the second direction.

摘要： A motor driving device, which drives a DC motor, includes a motor driving unit, a status determination unit, and an initial value renewal unit. The motor driving unit repeatedly performs a change-over, wherein the motor driving unit changes an amount of a current inputted into the DC motor to an initial value at a predetermined timing, and then gradually increases the amount of the current from the initial value, in order to slowly move a driving target, driven by rotational force of the DC motor, in a moving direction. The status determination unit determines whether or not the driving target is in a predetermined status. The initial value renewal unit changes the initial value when the status determination unit determines that the driving target is in the predetermined status.
