A switcher transmits, to an extractor/signal determiner, a converted current signal generated by a current-voltage converter when a converted current signal determiner determines that the converted current signal is generated by transmission of a current signal over a communication line, in the meantime, performs a switch-over so as not to transmit, to the extractor/signal determiner, a converted voltage signal generated by a voltage sensor. In addition, the switcher transmits, to the extractor/signal determiner, the converted voltage signal when a converted voltage signal determiner determines that the converted voltage signal is generated by transmission of a voltage signal over a communication line, in the meantime, performs a switch-over so as not to transmit, to the extractor/signal determiner, the converted current signal generated by the current-voltage converter.

摘要:
A sampler samples a receive signal received via a dedicated communication line. A data transfer rate adjuster measures a data transfer rate based on a number of start bit samples contained in the receive signal. A bit determiner makes a bit determination regarding the receive signal at the data transfer rate measured by the data transfer rate adjuster, to thereby acquire serial data contained in the receive signal. A transmitter sends, via the dedicated communication line, a transmit signal containing serial data sent by an MPU. An MPU communicator outputs to the transmitter the serial data sent by the MPU, and outputs to the MPU the serial data acquired by the bit determiner. The data transfer rate adjuster adjusts, when the transmitter sends the transmit signal multiple times at different data transfer rates, the data transfer rate based on the receive status of respective response signals thereto.

摘要:
A power-line communication device in which a control signal is superimposed on a power line between a switching power supply and a unit to be controlled to which an output of the switching power supply is supplied, so that the control signal is transmitted to the unit. At the same time, a switching noise generated by the switching power supply is monitored and communication is started by using the switching noise, as a synchronizing signal. Subsequently, communication can be performed during the intervals between the switching noises so that erroneous signal detection is reduced.

Disclosed are a frequency modulation apparatus and a frequency modulation method for generating an image clock that is used for turning on/off a laser beam that scans an image bearing member, such as a photosensitive drum. The frequency modulation apparatus divides, into a plurality of segments for each pixel, a main scan line on an image bearing member, and calculates auxiliary clock periods based on a reference clock period and variable-magnification coefficients corresponding to the segments. Then, the frequency modulation apparatus generates image clocks for the respective segments based on an initial predesignated period value and the obtained auxiliary clock periods. Furthermore, the frequency modulation apparatus includes a detecting device for detecting a difference between a reference value stored in a memory and an actual laser irradiation location, and corrects a shift in the laser irradiation location in accordance with the detection results obtained by the detecting device.
