摘要： An on-demand type ink jet printer, and an ink droplet projecting device used in this printer are disclosed. This device operates in the following way: a piezo-electric element transmits the pressure generated by its vibration first to the pressure transmitting medium of a non-solid matter; through this medium, the pressure is transmitted to the passive vibrating means being in contact with the ink to be projected, and facing the orifice through which ink is projected, thereby vibrating this vibrating means, and by the pressure generated by the vibration, ink is projected through the orifice. With such a structure, the assembling work of this device is easy; uniform projection characteristics are achieved, and moreover, the problem of air suction with resultant projection failure is eliminated.

摘要： The thermal transfer printer of the present invention prevents slackening of recording paper by exerting a braking force upon a recording paper roll to give a back tension to the recording paper when one of the colors of an ink sheet coated with inks of a plurality of colors is thermal-transfer-printed. The recording paper is unwound from the roll thereof in the forward direction and by rotating the recording paper roll in the backward direction the recording paper is rewound. A roller for carrying the recording paper is stopped or braked at the downstream side of the platen when the recording paper is carried in the backward direction for the thermal transfer printing by the next color.
摘要翻译：本发明的热转印打印机通过在记录纸卷上施加制动力来防止记录纸的松弛，从而当涂覆有多种颜色的油墨的油墨纸的颜色之一为热转印。记录纸在向前的方向从其卷展开，并且通过使记录纸在向后的方向上旋转，记录纸被倒带。当记录纸被向后方移动以进行热转印打印时，用于携带记录纸的辊被停止或制动在压板的下游侧。

摘要： A thermal transfer recording apparatus, such as a thermal transfer printer, which winds up at constant speed an ink sheet having ink to be transferred while applying a constant tension to the ink sheet by a DC motor through a speed reduction mechanism, so that the respective rotation speed and torques, when a wind-up roll is of a minimum diameter or a maximum diameter, are computed from the feed speed and tension of the ink sheet to thereby obtain a desired gradient in a chart of the relationship between the torque and the rotation speed of the DC motor, the gradient deciding a reduction ratio of the deceleration mechanism and the driviing voltage of the DC motor being decided. Hence, even though the wind-up roll varies in an external form, variation in tension applied to the ink sheet and that in the feed speed can be restricted.
摘要翻译：一种热转印记录装置，例如热转印打印机，其通过减速机构通过直流电动机以一定速度卷起具有要转印的油墨的油墨片，同时通过直流电动机向油墨纸施加恒定的张力，使得各自根据油墨纸的进给速度和张力计算卷取辊是最小直径或最大直径时的转速和转矩，从而在转矩和转矩之间的关系的图表中获得期望的梯度决定直流电动机的转速，决定减速机构的减速比和直流电动机的上升电压的坡度。因此，即使卷取辊以外部形式变化，可以限制施加到油墨片的张力变化和进给速度的变化。
