ABSTRACT:
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.
