摘要： Disclosed is a printing plate, for an electrophotographic process, which comprises an electroconductive support and a photosensitive layer formed on the electroconductive support, in which the photosensitive layer is formed by incorporating (a) a trisazo pigment represented by the general formula (I) and (b) at least one member selected from perynone pigments and anthanthrone pigments as photoconductive substances and (c) at least one electron donor substance as a sensitizer in an alkali-soluble binder resin. This printing plate has a high sensitivity and a printing image having a high quality is formed on the printing plate without contamination of the non-image area due to the electrophotography, and prints having a high-quality image can be obtained by using this printing plate.

摘要： The thermal transfer printer of the present invention is provided with a cam follower mounted on a thermal transfer head in one body and an eccentric cam, which is controlled within a semicircle so as to be positioned at either a first position for releasing it from the cam follower to press the thermal transfer head to a platen or a second position for pressing it to release the thermal transfer head from the platen, as a construction for pressing the thermal transfer head to the platen and releasing the thermal transfer head from the platen, whereby the mechanism for pressing the thermal transfer head to the platen and releasing the thermal transfer head from the platen itself can be remarkably small-sized and is simple in action due to its remarkably small working quantity, the printer can be small-sized as a whole and improved in reliability of operation as well as durability. Furthermore, the thermal transfer printer can be stably carried out the subsequent controls after initial powering, since the positional relation between the thermal transfer head and the platen is controlled so as to be initially set to the predetermined relation without delay when it is initially powered.
摘要翻译：本发明的热转印打印机设置有安装在一体的热转印头上的凸轮随动件和偏心凸轮，所述偏心凸轮被控制在半圆内，以便被定位在第一位置以将其从凸轮释放随动件将热转印头压到压板或第二位置，用于将其压出以将热转印头从压板上释放，作为将热转印头压到压板上并将热转印头从压板释放的结构，由此将热转印头压到压板上并将热转印头从压板本身释放的机构可以显着地小型化，并且由于其非常小的加工量而具有简单的作用，因此打印机整体上可以小型化并提高了操作的可靠性以及耐用性。此外，由于热转印头和压板之间的位置关系在最初被供电时被初始设定为预定关系而没有延迟，所以热敏转印打印机可以稳定地执行初始供电之后的后续控制。

摘要： The present invention relates to a method and a circuit for enhancing a fine line in the direction perpendicular to the arraying direction of the printing elements (i.e., in the direction of moving the printing paper) of a line printer which prints by applying either thermal elements or wires giving dot impact, and in which, for example, supposing the successive 4 printing elements comprising A, B, C and D, when the printing element C prints black and all others do white, the printing element C prints black and the other print while, the printing element B is made to print black to enhance a fine line by printing with two printing elements, so that the total visibility of the fine line is improved.
