摘要： A speed control portion of a motor driving device performs a deceleration control of decelerating a rotation speed of a driving motor based on a first pulse signal for the deceleration control that includes a plurality of pulses whose pulse width corresponds to each commanded speed to the driving motor. A pulse signal output portion generates the first pulse signal and a second pulse signal and outputs the second pulse signal to the speed control portion after outputting the first pulse signal to the speed control portion, wherein the pulse width of the first pulse signal changes by obeying a predetermined rule that corresponds to a deceleration tendency of the rotation speed during the deceleration control, and the second pulse signal does not obey the predetermined rule. When a determination processing portion determines that the second pulse signal is included in an input signal, the deceleration control is ended.

摘要： A conveying device which can determine whether an error occurred therein. When a transmission unit is in a transmission state, a sheet feed roller is driven by a DC motor to perform first driving for conveying a sheet up to a conveying roller. The occurrence of an error with respect to the sheet feed roller is determined based on information obtained from an encoder during the first driving. When the occurrence of an error is determined, second driving is performed. A conveyance error is determined based on a count value during the first driving and a count value during the second driving, which are both obtained from the encoder.
