| 主权项 | 1. A conveying device comprising: a conveyer unit conveying a sheet; a motor for driving the conveyer unit; an estimate device for estimating temperature of the motor based on a rotation amount and a stop period of the motor; and a determination device to determine whether to drive the motor either in a first mode in which the motor is continuously rotated or in a second mode in which the motor is intermittently rotated based on an estimation result of the estimate device. | ||
