Document Type and Number:
Japanese Patent JP5771960
Kind Code:
B2
Abstract:
To rotate a transport motor and to stop a carriage motor at an ADF reading angle, a control unit outputs a first and a second signal to a first and a second D/A converter, and a power on/off signal to an A-phase driver circuit for the carriage motor. The D/A converters convert the signal to a first and a second voltage. A transport motor driver supplies power to the transport motor on the basis of the first voltage, and a carriage motor driver turns on and off power supply to the A-phase on the basis of the first voltage and the power on/off signal, and supplies power to a B-phase on the basis of the second voltage.
