Abstract
An image reading apparatus includes a reading unit, a feeding unit, a carriage holding the reading unit, a motor, a motor-side transmission gear, a feeding unit-side transmission gear, a carriage-side transmission gear, a switching gear which switches between a meshing state of meshing with the feeding unit-side transmission gear at a feeding unit-side position and a meshing state of meshing with the carriage-side transmission gear at a carriage-side position, a restraint member which applies a restraint force for restraining the switching of the switching gear, and a motor control unit which when switching the switching gear between the carriage-side position and the feeding unit-side position, executes a large torque control of controlling the motor to generate a switching torque which is larger than a moving reading torque to be generated by the motor at a time of document reading when executing a moving reading.
