Claim Text:
1. A paper transport device comprising: a motor; a transport portion that transports paper by using a power generated by the motor; a determination portion that, during a period when the paper is transported in a transport direction, determines whether or not a state in which a load larger than or equal to a predetermined load is applied to the motor has continued during a predetermined period; and a motor control portion that, when a result of the determination indicates that the state in which a load larger than or equal to the predetermined load is applied to the motor has continued during the predetermined period, causes the motor to rotate in a direction reverse to a normal rotation direction that is a direction in which the motor rotates in order to cause the paper to be transported in the transport direction, until an amount of the rotation of the motor in the direction reverse to the normal rotation direction reaches a predetermined rotation amount, and then causes the motor to rotate in the normal rotation direction again, in a state of causing an amount of electric current input to the motor to be larger than an amount of electric current that has been caused to be input to the motor in order to cause the paper to be transported in the transport direction before an occurrence of the state in which a load larger than or equal to the predetermined load is applied to the motor.
