  • Patent number: 9319561
    Abstract: A scanner unit includes, a CIS module having a light source unit, and a CIS which receives reflected light which is emitted in the light source unit; a carriage motor which is provided in the vicinity of the CIS module, and operates along with heat when reading out using the CIS module; a determination unit which determines whether or not dark period measurement data read out using the CIS module in a dark period is in a predetermined range of a reference dark period which is set corresponding to a temperature of the carriage motor; and a control unit which controls the carriage motor so as to limits an operation of the carriage motor in read processing, when the dark period measurement data is not in the range of the reference dark period.

  • Patent number: 8553297
    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.

  • Patent number: 6499820
    Abstract: An apparatus and a method of generating waveforms for driving an ink-jet print head. Waveform data for the overall head-driving waveforms per given unit are written in waveform buffers and then sequentially retrieved at a given timing for analog conversion to obtain an analog head-driving waveform signal. Various head-driving waveforms are thus programmably generated.
