Patent number: 8553297Abstract: 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.Type: GrantFiled: December 6, 2011Date of Patent: October 8, 2013Assignee: Seiko Epson CorporationInventor: Hideo Taki
