摘要： In a dot matrix line printer, a pair of pin tractors for feeding a print paper are operatively connected to a paper feed motor, and a tension roller mechanism disposed beneath a platen is operatively connected to a separately provided drive motor. To eliminate a paper slack which may occur when the feeding of the print paper is stopped after creating many blank lines, the drive motor is energized for a short period of time immediately before the paper feeding is ended. The tension roller mechanism which is made up of a plurality of rollers pulls the print paper in a direction opposite the paper feeding direction to thus prevent the print paper from slackening.
摘要翻译：在点阵线打印机中，用于馈送打印纸的一对销拖拉机可操作地连接到供纸马达，并且布置在压板下方的张紧辊机构可操作地连接到单独提供的驱动马达。为了消除在创建许多空白线后停止打印纸的供纸时可能发生的纸张松弛，驱动电机在进纸结束之前立即通电短时间。由多个辊构成的张紧辊机构沿与进纸方向相反的方向拉动打印纸，从而防止打印纸松弛。

摘要： When print mode of a printing device is switched to a print mode with a higher print speed, after the direction of shuttle movement is reversed, a time duration that driving current is applied to a reversing coil is increased, so that shuttle speed is increased to a target speed. A time duration that driving current is applied to a constant velocity coil is decreased accordingly. On the other hand, when the print mode is switched to a print mode with a lower print speed, the time duration that driving current is applied to the reversing coil is decreased, and the time duration that driving current is applied to the constant velocity coil is increased accordingly. In this way, the print modes of the printing device can be switched quickly without stopping printing operations, thereby enhancing throughput.
摘要翻译：当打印装置的打印模式被切换到具有更高打印速度的打印模式时，在梭子运动的方向反转之后，驱动电流施加到反转线圈的持续时间增加，使得梭子速度增加到目标速度。驱动电流施加到恒速线圈的持续时间相应地减小。另一方面，当打印模式切换到具有较低打印速度的打印模式时，驱动电流施加到反转线圈的持续时间减小，并且驱动电流施加到恒速线圈的持续时间相应增加。以这种方式，可以快速切换打印装置的打印模式而不停止打印操作，从而提高吞吐量。

摘要： A hammer bank mounted on direct drive bearings reciprocally moves along a shaft. Springs provided at each end of the shaft supplies repulsive force to the hammer bank. When sheet feed operations for a plurality of carriage returns are performed, the hammer bank is stopped at a predetermined position away from the springs. When the reciprocal movement of the hammer bank is restarted, the hammer bank is first moved to a reverse position where the repulsive force of the spring is in the maximum. Then, the hammer bank is accelerated by utilizing the repulsive force of the spring and restarts the reciprocal movement.
摘要翻译：安装在直接驱动轴承上的锤子组沿着轴往复移动。在轴的两端设置的弹簧向锤子组提供排斥力。当执行用于多个回车的纸张进给操作时，锤组在远离弹簧的预定位置处停止。当锤组的往复运动重新开始时，锤组首先被移动到弹簧的推斥力最大的倒档位置。然后，通过利用弹簧的排斥力来加速锤组，并重新启动往复运动。

摘要： A device includes a temperature control member and a linearly-contact member. The temperature control member has an outer peripheral surface to contact a conveyed substrate to which liquid is applied, and heats or cools the substrate. The linearly-contact member contacts the substrate and the temperature control member on an upstream side from a contact position between the substrate and the temperature control member in a conveyance direction of the substrate.

摘要： In a dot line printer that prints, for example, eight lines of dots with each single scan of a hammer bank, wherein the pins of hammers for printing the first dot line and the eighth dot line or for printing the second dot line and the seventh dot line are shifted from their respective home positions to compensate for an error causing impressions of dots to be made at an unequal pitch in a sheet feed direction as a result of consecutive forward and backward movements of the hammer bank.
