摘要： Plural sensors are arranged respectively for plural toner colors, and oscillate to generate and output detection signals with frequencies corresponding to toner densities using oscillator circuits. An analog switch selects one detection signal among the detection signals. A filter decreases amplitude of the selected detection signal. A first signal line transmits the detection signal with the decreased amplitude. A comparator compares the transmitted detection signal with a predetermined threshold value and outputs as the detection signal a signal of which a level is set as a high level or a low level in accordance with the comparison result, and thereby increases amplitude of the detection signal. A receiver-side IC receives the detection signal with the increased amplitude at a predetermined port, determines a frequency of the received detection signal, and determines the toner density on the basis of the determined frequency.

摘要： Data comprising a pulse signal is divided into predetermined data segments. The number of pulse-signal fluctuations in the data segment is counted. A transmitter transmits the unchanged data to a receiving portion in a case where the number of pulse-signal fluctuations does not exceed a predetermined number. On the other hand, in a case where the number of pulse-signal fluctuations exceeds the predetermined number, the pulse signal is converted so as to be unchanged at the fluctuation of the pulse signal but to be fluctuated when the pulse signal does not fluctuate. Then, the transmitter transmits the converted pulse signal to the receiving portion wherein only the converted pulse signal is converted to the original pulse signal.

摘要： An image processing device includes a modulation clock generator, a line synchronization signal generator, a line image sensor, and an image processor. The modulation clock generator is configured to generate the modulation clock by modulating a frequency of a reference clock at a predetermined modulation cycle. The line synchronization signal generator is configured to generate, on the basis of the modulation clock, a line synchronization signal whose line cycle varies from line to line. The line image sensor is configured to sequentially read an image of one line of a document at a timing corresponding to the line synchronization signal and to output image data. The image processor is configured to process the image data on the basis of the modulation clock.
