Original Abstract Submitted
An image reading device includes a DC motor, a roller driven by the DC motor, a reading unit configured to read an image from a document conveyed by the roller, and a control unit configured to control driving of the DC motor. The control unit is configured to detect a power load value of the DC motor. The control unit is configured to determine that the power load value of the DC motor exceeds a first threshold value in a state in which the control unit controls the DC motor to convey the document at a first conveyance velocity, and then, control the DC motor to convey the document at a second conveyance velocity lower than the first conveyance velocity.
