Latest Patents

Ichimura holds a patent for an "Optical writing head driving device." This invention involves a printer controller that sets compensation values to address positional deviations of LED array chips. The device utilizes a delay circuit section, which is controlled via a shift register and a latch circuit. The shift register sequentially acquires bitmap data from the printer controller and supplies it to an AND gate through the latch circuit. Upon receiving a strobe signal from the printer controller, the delay circuit section supplies the strobe signal to the AND gate after a preset delay time. The AND gate generates drive signals that correspond to the input bitmap data and the strobe signal, ensuring that the LED array chips emit light at the correct timings to form images without positional deviations. Notably, at least one of the LED array chips is unaligned with adjacent ones, and the preset compensation values are obtained through interpolation based on detected positional deviations.
