Latest Patents

Asako 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 provides the strobe signal to the AND gate after a predetermined delay time. The AND gate generates drive signals that correspond to the input bitmap data and the strobe signal, which are then sent to the LED array chips. This technology ensures that the LEDs emit light at the correct timings, allowing for the formation of images without positional deviations. Notably, at least one of the LED array chips may be unaligned with adjacent chips, and compensation values are derived through interpolation based on detected positional deviations.
