A cutter apparatus includes a cutter roller with a cutter blade, and an anvil roller that receives the cutter blade. An annular protruding section is provided to an outer circumferential face of one of the cutter roller and the anvil roller, and comes into contact with the other roller. First and second motors drive the cutter roller and the anvil roller. A first motor control unit controls the first motor by position control or speed control. A second motor control unit controls the second motor. The anvil roller rotates to follow the cutter roller by a torque transmitted from the cutter roller via the annular protruding section, and a supplementary torque is imparted from the second motor to the anvil roller, based on a control by the second motor control unit, so as to assist a rotation of the anvil roller following the cutter roller.
