Abstract
A motor control device includes: a first motor that provides a driving force for rotating a roll on which a roll paper is wound to supply the roll paper from the roll; a second motor that provides a driving force for driving a transport driving roller which is provided on a downstream side than the roll along a supply direction of the roll paper and used for transporting the roll paper; a load measuring unit that measures a relationship between a load on the first motor and a driving speed of the first motor when the second motor is not driven and the first motor is driven; and a motor control unit that simultaneously drives the first and second motors at a certain timing, provides to the first motor an interpolation output based on the measurement result of the load measurement unit and a driving speed of the second motor during the control, and transports the roll paper to the downstream side by driving the second motor.
