摘要： In an inkjet device that ejects ink on a medium with an inkjet head, data conversion software generates ejection data and timing control data from pattern data that describe patterns of ejection target pixels. A timing control board outputs a drive waveform generation trigger signal and a data transfer request signal to a drive waveform generator board and a memory board, respectively. The drive waveform generator board generates drive waveforms according to drive waveform generation trigger signal. The memory board transfers ejection data to the driver board according to the data transfer request signal. The driver board controls ink ejection of each nozzle based on the ejection data. Therefore, the inkjet device is capable of highly accurate positioning of ink ejection with almost no increase in the amount of data.

摘要： The invention aims at provision of an optical scanner in which an optics required for equalizing an optical magnification in a scanning range is produced with high accuracy, so that intervals among a plurality of scanning lines on a to-be-scanned surface are even in the scanning range. The scanning optics includes a refraction surface and a reflection surface whose sub-scanning-direction curvature radii vary continuously. The reflection surface is disposed on the to-be-scanned surface side of the refraction surface. The curvature radius of the reflection surface varies symmetrically with respect to the optical axis, and the curvature radius of the refraction surface varies asymmetrically with respect to the optical axis.

摘要： A developing unit includes a plurality of developing rolls over which a developer is conveyed and supplied onto an image carrier which is rotatably supported; and at least one pair of the developing rolls being adjacent to each other. In the pair of the developing rolls, one developing roll rotates in a direction opposite to a rotary direction of the image carrier, and the other developing roll rotates in the same direction of the rotary direction of the image carrier. A regulation member is interposed between the pair of the developing rolls. The regulation member regulates a conveyed amount of the developer. The regulation member is disposed to be opposed to a magnet which is provided within the two adjacent developing rolls. A polarity of the magnet in the pair of developing rolls opposed to each other is different from each other.
