摘要： An ink-jet recording head includes a recording head and pressure damper assembly module including a recording head part at a lower position having nozzle holes on an under surface and an ink passage communicating with the nozzle holes, and a pressure damper part higher than the recording head part having an ink containing chamber inside. The ink-jet recording head further includes first flexible tube supplying ink in the ink containing chamber to the ink passage and connecting an ink discharge part communicating with the ink containing chamber and an ink supply part at one end side in the recording head part communicating with one end of the ink passage; and a second flexible tube connected with another end side in the recording head part and communicating with another end of the ink passage. At least the inside of the first flexible tube is filled with the ink.

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： 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。
