ABSTRACT:
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.
