摘要： PROBLEM TO BE SOLVED: To provide a printer capable of suppressing a deterioration in printing quality due to the vibration of a carrier.
SOLUTION: The printer controls of the movement of the carrier holding a printing head by controlling the rotation of a carrier motor, in this case the printer controls the rotation speed of the carrier motor by feedbacking the same such that the moving speed of the carrier becomes a predetermined targeted speed. The printer first moves the carrier at the same speed as a printing speed by printing command, executes maintenance operation for preventing the occlusion of the printing head (#23), and determines whether or not vibration occurs in the carrier in the maintenance operation (#24) when receiving the printing command (#21). The printer 1 changes the driving parameter of the carrier motor (#25) when the vibration occurs in the carrier (YES in #24) and controls the rotation speed of the carrier motor feedbacking the same using the changed driving parameter to execute the printing operation (#26).

摘要： PROBLEM TO BE SOLVED: To quickly drive a conveyance roller along with drive of a drive motor while avoiding inclination of a planet gear arranged in a drive force transmission path from the drive motor to the conveyance roller in a scanner device.
SOLUTION: The drive force transmission path is provided with a solar gear 31 driven by the drive motor, an arm 32 which is pivotally supported by the solar gear 31 and rotates and the planet gear 33 which is pivotally supported by the arm 32 so as to engage with the solar gear 31 and which engages with a transmission gear on the side of the conveyance roller when the drive motor is driven in a predetermined direction. At an axis part 33a of the planet gear 33, a coil spring 39 which energizes the planet gear 33 so as not to be inclined is wounded and rotation resistance is given to the planet gear 33. When the drive motor is temporarily drive and stopped in the direction opposite to the predetermined direction, the planet gear 33 stops a little away from the transmission gear and the time is reduced until the planet gear engages with the transmission gear when the drive motor is driven after that.

摘要： PROBLEM TO BE SOLVED: To discriminate the kind of an image read sensor in a scanner even when reference voltages of different kinds of image read sensors are in the level or the reference voltages have variance. SOLUTION: When reading a white reference adjustment sheet by an image sensor while turning on an LED array (S6), the CPU of the scanner decides the total number of output pixels, which is the number of photodetecting elements having output values larger than a predetermined gray scale (S7) and decides the kind of the image read sensor on the basis of the decision result (S8). Consequently, even when the reference voltages of the different kinds of image read sensor are in the same level or the reference voltages have the variance, the kind of the image read sensor can be discriminated. According to the discriminated kind of the image read sensor, an offset set value and a gain set value that AFE holds are changed and the image read operation is controlled using reference voltage data and start position data corresponding to the kind of the image read sensor (S9 to S12).

摘要翻译：要解决的问题：即使在不同种类的图像读取传感器的参考电压处于电平或参考电压有差异的情况下，也可以区分扫描仪中的图像读取传感器的种类。
解决方案：打开LED阵列时，通过图像传感器读取白色参考调整片（S6）时，扫描仪的CPU决定输出像素的总数，即输出值较大的受光元件的数量（S7），并且基于判定结果来决定图像读取传感器的种类（S8）。因此，即使不同种类的图像读取传感器的参考电压处于相同电平或参考电压具有差异，也可以区分图像读取传感器的种类。根据图像读取传感器的识别种类，改变AFE保持的偏移设定值和增益设定值，并且使用与图像读取传感器的种类相对应的参考电压数据和起始位置数据来控制图像读取操作 S9〜S12）。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To efficiently cool a heating element without causing a cost increase in a laser beam printer. SOLUTION: A cooling fan 33 for cooling a fixing roller 8 is disposed while keeping a predetermined gap 51 from a power supply circuit board 12. A first partition 19a and a second partition 19b are formed on the inner surface of a side cover member 19. Hot air near the heating elements 31 and 32 mounted on the power supply circuit board 12 is guided by the first partition 19a and the second partition 19b, sucked by the cooling fan 33 from the gap 51 and discharged to the outside of a cover member 14. Meanwhile, a duct member 34 is disposed between the fixing roller 8 and the cooling fan 33, and the hot air near the fixing roller 8 passes through the inner part of the duct member 34, is sucked by the cooling fan 33 and discharged to the outside of the side cover member 19.

摘要： PROBLEM TO BE SOLVED: To provide a printer which can maintain an optimum print quality at all time and enables a user to execute a desired print setting easily for comfortable use of the printer.
SOLUTION: The printer periodically cleans the nozzle of a print head to maintain an optimum print quality all the time. When the printer receives a print instruction from an external device (YES in #1), the printer automatically sets print setting to the most frequently used print setting (#2). When the printer receives an instruction from the external device for changing the print setting (YES in #3), the printer changes the print setting correspondingly (#4). When the printer receives an instruction from the external device for deciding the print setting (YES in #5), the printer executes operation for printing images on a sheet 2 based on the print setting already set (#6). Thus, when the printer receives a print instruction from the external device, the most frequently used print setting is automatically set, enabling a user to easily set the print setting desired with a reduced number of operation.
