    • In a carriage assembly of a printer employing a movable print head, bosses provided with respective bearing supporting holes, each inner circumferential surface of which has a predetermined radius of curvature, are formed at a side of a carriage, and bearing bushings, each of which has an outer circumferential surface having a different predetermined radius of curvature corresponding to that of the bearing supporting hole, are also formed so as to make a spherical pair with the bearing supporting hole. A shaft through-hole, through which a guiding rod is inserted slidably, is formed through each bearing bushing. The bearing bushing can rotate freely in the bearing supporting hole, and therefore, the axes of the carriage assembly and the guiding rod can be aligned automatically.
    • 在采用可移动打印头的打印机的托架组件中,在托架的一侧形成有各自的轴承支承孔的凸台,每个轴承支承孔的每个内圆周表面均具有预定的曲率半径, 具有与轴承支撑孔相对应的具有不同的预定曲率半径的外周面也形成为与轴承支撑孔成球形。 通过每个轴承衬套形成导向杆可滑动插入的轴通孔。 轴承衬套可以在轴承支撑孔中自由旋转,因此滑架组件和导杆的轴线可以自动对齐。

    • There is provided an apparatus and a method of detecting a home position of a carriage, achieving a less manufacturing cost. The apparatus includes a position detecting part to detect a position of a carriage driven by a motor; a first drive control part to control the motor so that the carriage is transferred toward a frame of a printer until being stopped, the frame being provided at a home position range side; a second drive control part to control the motor so that the carriage is transferred toward another frame of the printer until being stopped, the other frame being provided opposite to the frame provided at the home position range side; a third drive control part to control the motor so that the carriage is transferred to a predetermined position close to the home position range; and a selection control part to select one of the first, the second, and the third drive control parts and control the selected drive control part, thus detecting a home position of the carriage based on a result of the selective control and the output of the position detecting part.
    • 提供了一种检测托架的原位置的装置和方法,实现了较少的制造成本。 该装置包括:位置检测部,用于检测由马达驱动的托架的位置; 第一驱动控制部分,用于控制电动机,使得滑架朝向打印机的框架传送直到停止,框架设置在原始位置范围侧; 第二驱动控制部分,用于控制马达,使得滑架被转移到打印机的另一个框架直到停止,另一个框架设置在与设置在原始位置范围侧的框架相对; 第三驱动控制部分,用于控制电动机,使得滑架转移到靠近原位置范围的预定位置; 以及选择控制部件,用于选择第一,第二和第三驱动控制部件中的一个,并控制所选择的驱动控制部件,从而基于选择控制的结果检测托架的原始位置,并输出 位置检测部。
