    • The apparatus of the present invention is provided with a stain preventing element provided between a print drum and a hammer and adapted to shield alternate digits to be printed, said stain preventing element being shiftable in the transverse or advancing direction of print sheet. Said hammer is an intermediate hammer which is set to a predetermined initial position from an unsteady position upon the turning on of the power supply, and simultaneously necessary preparations such as paper feeding and ink application onto the print drum prior to the printing are performed. Also there is provided a stain preventing mechanism for multi-color printing, and the above-mentioned stain preventing member is provided with a means for preventing ink diffusion. Also the paper feed plunger etc. is structured similar to the said hammer thereby rendering the entire apparatus smaller and more compact.
    • 本发明的装置设置有防污染元件,其设置在打印鼓和锤之间并且适于屏蔽要打印的替代数字,所述防污染元件可在打印片材的横向或前进方向上移动。 所述锤是在电源接通时从不稳定位置设定到预定初始位置的中间锤,并且在打印之前同时执行诸如进纸和油墨施加到打印鼓上的必要准备。 另外,还提供了一种用于多色印刷的防污染机构,并且上述防污染部件设置有防止油墨扩散的装置。 此外,进给柱塞等也被构造成类似于所述锤,从而使整个装置更小更紧凑。
