    • A printer is provided to improve the conveying accuracy of a Y-bar, thus improving printed image quality. The printer includes the Y-bar that extends in a first direction above a flatbed on which a medium is mounted, holds an ink droplet ejecting head unit so that the head unit is movable in the first direction, and is held so as to be movable with respect to the flatbed in a second direction perpendicular to the first direction. The printer includes a drive mechanism that conveys the Y-bar in the second direction, a drive control device that carries out a drive control of the drive mechanism, and a measuring device that directly measures an amount of movement of the Y-bar with respect to the flatbed. The drive control device corrects controlled variables of the drive mechanism based on the amount of movement of the Y-bar measured by the measuring device.
    • 提供了一种打印机来提高Y-bar的传送精度,从而提高打印图像质量。 打印机包括Y形杆,其沿着安装有介质的平板上方的第一方向延伸,保持墨滴喷射头单元,使得头单元可沿第一方向移动,并被保持为可移动的 相对于平板在垂直于第一方向的第二方向上。 该打印机包括:沿第二方向传送Y形杆的驱动机构,执行驱动机构的驱动控制的驱动控制装置;以及直接测量Y型杆的移动量的测量装置, 到平房。 驱动控制装置基于由测量装置测量的Y形杆的移动量来校正驱动机构的受控变量。

    • A pen recorder has two movable bases adapted to be movable in directions along a platen, one of the bases being driven in directions along the platen. A plurality of pens are mounted in parallel on one of the bases, and a hammer is mounted on the other base for pressing any one of the pens toward the platen. The base which is not driven has a lock lever adapted to engage with a plurality of portions of the base which is driven. The base which is not driven further has an urging lever for driving the lock lever. The urging lever is slidably mounted on a pen changeover shaft rotated by a driving mechanism. The pen recorder further has a spring for urging the lock lever in the locking direction, as well as forcing the urging lever to abut against the lock lever in the unlocking direction. Also disclosed is a method of setting the initial position of the pen recorder. The method comprises the steps of: starting a pulse motor for pulling one of the bases under the state where the bases are connected through the lock mechanism, to move one of the bases to its dead point; making the pulse motor step out after the dead point is reached; canceling the locking to separate the bases from each other; moving the other base to its dead point; and making the pulse motor step out again after the other base reaches its dead point, thereby to set the initial positions of both the bases.
    • 笔式记录器具有两个可移动的基座,其适于沿着压板的方向移动,其中一个基座沿着压板的方向被驱动。 多个笔平行地安装在一个基座上,并且锤子安装在另一个基座上,用于将任何一个笔压向压板。 未被驱动的基座具有适于与被驱动的基座的多个部分接合的锁定杆。 未进一步驱动的基座具有用于驱动锁定杆的推压杆。 推动杆可滑动地安装在由驱动机构旋转的笔转换轴上。 笔式录音机还具有用于在锁定方向上推动锁定杆的弹簧,以及迫使推动杆在解锁方向上抵靠锁定杆。 还公开了一种设置笔式记录器的初始位置的方法。 该方法包括以下步骤:在通过锁定机构连接基座的状态下启动用于拉动其中一个基座的脉冲电机,将其中一个基座移动到其死点; 使脉冲电机在达到死点后退出; 取消锁定以将基座彼此分开; 将另一个基地移动到其死点; 并且在另一个基座达到其死点之后使脉冲电机再次出门,从而设定两个基座的初始位置。
