    • A printing apparatus arranged to perform printing while a monochrome printing head and a color printing head are moved in a direction in which the two heads are moved, the printing apparatus being arranged to print a plurality of patterns in which the relative quantity of deviation of printing timings of the two heads is changed in a stepped manner to cause a user to select a pattern having the smallest quantity of deviation among the plural patterns. Then, the selected pattern is used as a central value when a plurality of patterns in which the relative quantity of deviation of the printing timings of the two heads is changed in a stepped manner are furthermore printed to cause the user to select a pattern having a smallest quantity of deviation from the plural patterns. The above-mentioned process is repeated as necessary. As a result, the operation which is performed by the user to adjust the printing position can simply and easily be performed. Control is performed in such a manner as to change color to be printed by the color printing head whenever an adjustment mode in which the relative quantity of deviation of the printing timing is adjusted is started.
    • 一种打印装置,其被设置为在单色打印头和彩色打印头沿着两个头移动的方向移动时执行打印,打印装置被布置成打印多个图案,其中打印的相对偏离量 以分阶段方式改变两个头的定时,使得用户选择多个图案中具有最小偏差量的图案。 然后,当打印两个头的打印定时的相对偏移量以阶梯方式改变的多个图案时,将所选择的图案用作中心值,以使用户选择具有 最小数量的偏离多个模式。 必要时重复上述过程。 结果,可以简单且容易地执行由用户执行的用于调整打印位置的操作。 只要开始调整打印定时的相对偏差量的调整模式,则以这样的方式进行控制,即,改变要由彩色打印头打印的颜色。

    • A printer which is compact, can accurately supply paper and has low noise characteristics. Additionally, the printer enables easy correction of paper jams and can be selectively operated in various modes according to the user's preference. The printer includes a paper feed roller (354) which is pivotable between a paper feed position and a non-feeding position, a drive force transmitting mechanism (355, 356, 358) for transmitting a drive force to the paper feed roller (354), a carriage (600) reciprocatively movable along the width of the paper fed by the paper feed roller (354), and an intermediate transmission mechanism (337) attached to the side of the carriage (600). Only when the carriage (600) is in a stand-by position, the intermediate transmission mechanism (337) couples with the drive force transmitting mechanism to transmit to the paper feed roller (354) a paper-feed directional rotating force so as to rotate the paper feed roller (354) to the paper feed position. The intermediate transmission mechanism is preferably an idler (337) rotatably mounted on the side of the carriage (600). The paper feed roller (354) is preferably driven through a planetary gear mechanism including a sun gear (358) provided on a drive shaft, a paper-feed roller holder (356) rotatably mounted on the drive shaft, and a planetary gear coaxially provided with the paper feed roller (354) supported with the paper-feed roller holder (356).
    • 一种紧凑的打印机,可以准确地提供纸张并具有低噪音特性。 此外,打印机能够容易地校正卡纸,并且可以根据用户的偏好以各种模式选择性地操作。 该打印机包括可在供纸位置和非供纸位置之间枢转的供纸辊(354),用于将驱动力传送到供纸辊(354)的驱动力传递机构(355,356,358) ,沿着由供纸辊(354)供给的纸张的宽度往复移动的托架(600)和附接到托架(600)侧的中间传动机构(337)。 只有当托架(600)处于待机位置时,中间传动机构337与驱动力传递机构耦合,以便向送纸辊354传送供纸定向旋转力以便旋转 供纸辊(354)到送纸位置。 中间传动机构优选为可旋转地安装在滑架(600)侧的惰轮(337)。 供纸辊(354)优选地通过包括设置在驱动轴上的太阳轮(358)和可旋转地安装在驱动轴上的送纸辊保持器(356)的行星齿轮机构驱动,以及同轴地设置的行星齿轮 供纸辊(354)由送纸辊保持架(356)支撑。
