ABSTRACT:
The motor driving device includes a first function of supplying power to a motor so that the motor generates a driving force to drive a driven member, a second function of detecting a current flowing through the motor, a third function of performing a power supply control in order that a value of the current detected by the second function is maintained within a target range, a fourth function of performing a power supply operation in which the motor is supplied with power for a predetermined time period which is short enough to avoid the driven member from being driven by the motor, before the third function performs the power supply control, and a fifth function of making a judgment on a state of each of the first to third functions on the basis of the value of the current detected by the second function during the predetermined time period.
