摘要： A chamber support plate of an inkjet head is formed as a member different from a housing. The chamber support plate is formed with a plurality of grooves at high density by a dicing saw or the like. Piezoelectric elements are inserted into the grooves and adhered to a chamber plate. The plurality of grooves define comb teeth portions, which support the chamber plate at positions between adjacent piezoelectric elements.

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 dot line printer provided with an ordinary dot density printing mode, a low dot density or draft printing mode and a high dot density printing mode. A hammer bank provided with a plurality of printing hammers is reciprocally movable in a shuttling direction for dot impressions when the hammer bank is moved through a printing region, and the moving direction of the hammer bank is reversed at a reversing region where a printing sheet is fed in a line to line direction. A shuttle cam is provided which is drivingly connected to the hammer bank. The shuttle cam has a cam profile capable of providing a cam lift characteristic approximately intermediate between a cam lift characteristics of the ordinary printing mode and that of the low dot density printing mode. A shuttling velocity of the hammer bank is changed in accordance with the selected printing mode and position of the hammer bank.

摘要： A dot line printer for carrying out printing on a print paper while shuttling a hammer bank back and forth in a direction to traverse the print paper. To lower the peak level of the current flowed in an electromagnetic coil provided in association with a print hammer and to reduce an electric power consumption, a predetermined number of print hammers are divided, for example, into four groups A, B, C and D. The print hammers belonging to group A are arranged at a constant interval wherein three print hammers belonging to groups B, C and D are interposed between adjacent two print hammers of group A and are disposed in positions displaced toward the leftside group A hammer from their home positions defined by equally spaced apart positions between the adjacent two print hammers of group A. Currents are adapted to flow in the coils of the print hammers belonging to different groups, e.g., A and B, in overlapped relation to each other, whereby the levels of the currents flowed therein are lowered due to magnetic interaction by the coils of another group.

摘要： A printing hammer assembly is provided having a plurality of hammer springs arrayed side by side at a predetermined pitch in a shuttling direction of a hammer bank. A front yoke is provided in front of the hammer springs, and a plurality of rectangular grooves are formed at an upper portion of the front yoke so as to receive therein corresponding rectangular plungers provided at the hammer springs. A gap is defined between a side wall of the groove and a side wall of the plunger. The gap is sufficiently large for tolerating inaccurate assembly of the hammer springs and the front yokes. Further, a subordinate front yoke is provided on the front yoke at a position of an array of the grooves.
