摘要： An ink jet printer includes a distance adjust mechanism for adjusting in two steps a distance between a liquid nozzle-formed face of a print unit and the recording surface, and a unit having first and second cleaning members with different free end positions, lengths and/or thicknesses are arranged movable relative to the face and adapted to wipe a substance adhering to the face off of the face with a predetermined engagement condition. The substance is wiped off of the face by the first and second cleaning members having different engagement conditions when the face is a first distance from a recording surface, and is wiped off with the engagement condition of a wipe portion of the first cleaning member virtually equal to the engagement condition of a wipe portion of the second cleaning member associated with the first distance when the face is a second distance from the medium. Further, a height difference between the cleaning members is set almost equal to the distance the face is moved by the distance adjust mechanism.

摘要： When recording a gradation pixel by performing pseudo-halftone processing, the occurrence of unevenness in the density in the recorded image is suppressed. For that purpose, when recording a pseudo-halftone image using dot patterns, a dot-pattern table storing a plurality of different dot patterns is provided for each gradation value. One dot-pattern table is selected from N dot-pattern tables based on gradation-value information for each pixel. One dot pattern is selected from the selected dot-pattern table, based on position information indicated by the pixel, and recording is performed using the selected dot pattern. It is thereby possible to prevent the concentrated use of a particular nozzle of a recording head, and suppress the occurrence of unevenness in the density due to characteristics of the specific nozzle.

摘要： When highly redundant information that expresses five tones using 4 bits is transferred to a printer in terms of a unit data length in data transfer, efficiency is very poor. Hence, multi-valued data is quantized to 5-valued data, which is output as a 4-bit code that can express five values. 4-bit codes for three bits are combined to be converted into an 8-bit code. The 8-bit codes are packed into data of a 16-bit unit, and the packed data is transferred to the printer.

摘要： A printing method capable of printing a high-quality image at a high speed and low cost and a corresponding printing apparatus are disclosed. In this printing apparatus, a shading-corrected mask pattern for multipass printing control in consideration of the characteristics of each printing element of a printhead is generated. The size of the mask pattern in the conveyance direction of the printing medium is set to be an integer multiple of the conveyance amount of the printing medium per scanning of the printhead. Image data masked using the mask pattern is transferred to the printhead and printed. Alternatively, the conveyance-direction size of the mask pattern for masking print data in accordance with each pass printing of multipass printing is set to be equivalent to the number of nozzles of an ink-jet printhead having a plurality of nozzles arrayed in the conveyance direction of the printing medium, and the mask pattern is dividedly used for each pass printing. Any error of the position of a dot printed on the printing medium by an ink droplet discharged from each nozzle is detected in units of nozzles. Printing may be performed using a mask pattern generated such that a printing element with a small error is frequently used in accordance with the detection result, or performed such that the positions of print data are exchanged.

摘要： According to the invention, a power supply for an image sensing device is obtained from a printer to prevent consumption of the battery. When the image sensing device is connected to the printer, a power management unit checks if electric power can be supplied from the printer. When electric power can be supplied from the printer, the power management unit switches the power supply from the battery to a power supply receiving/supplying unit that receives electric power from the printer. In this case, if the remaining capacity on the battery is small, the battery is charged by electric power from the printer. Also, the luminance of a display unit is increased, or the operation frequency of a control unit is raised. On the other hand, when electric power cannot be supplied from the printer, the power management unit switches the power supply to the battery. In this case, the power management unit reduces consumption power by decreasing the luminance of the display unit or reducing the operation frequency of the control unit.

摘要翻译： 根据本发明，从打印机获得用于图像感测装置的电源，以防止电池消耗。 当图像感测装置连接到打印机时，电源管理单元检查是否可以从打印机提供电力。 当从打印机供电时，电源管理单元将电池的电源切换到从打印机接收电力的电源接收/供给单元。 在这种情况下，如果电池的剩余容量小，则通过来自打印机的电力对电池进行充电。 此外，显示单元的亮度增加，或控制单元的操作频率升高。 另一方面，当不能从打印机供电时，电源管理单元将电源切换到电池。 在这种情况下，电源管理单元通过降低显示单元的亮度或降低控制单元的操作频率来降低​​功耗。

摘要： In a system to which a plurality of devices are connected, each device has heretofore required a connector for an AC adapter and a connector for a signal line. Further, in order to arrange it so that the amount of power supplied to the overall system will not exceed a limit value, it has been required to adjust the amount of power during system use by turning the power source of each device on or off. According to the present invention, a signal line for data transfer and a power line for supply of power in a system connecting a plurality of devices are consolidated in a single cable to make it possible to connect both lines to one connector of each device. The power controller of a certain device acquires the properties of a plurality of devices connected to this device, decides the optimum power distribution and controls the power controllers of each of the other devices.
