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： 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： 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 droplet ejecting apparatus includes a recording head including nozzles, liquid chambers communicating with the respective nozzles and storing ink, and actuators for applying pressure to the respective liquid chambers; and a print control unit configured to generate drive signals for driving the respective actuators to eject droplets from the nozzles. The drive signal includes a first contracting waveform component for ejecting a droplet and a second contracting waveform component for further contracting the liquid chamber after application of the first contracting waveform component but not ejecting a droplet. The second contracting waveform component is output at oscillation-damping timing at which a pressure wave generated by the first contracting waveform component is damped, in a condition where an environmental temperature is high, and is output at resonating timing at which resonance with the generated pressure wave occurs, in a condition where the environmental temperature is low.
