Abstract
PURPOSE: To dissolve the troubles of dirty or blurred printing caused by the temperature changes by adopting heat-expansible material as a positioning means, where the position of a mask for preventing dirty printing is determined against a printing drum, in an impact printer using ink-roller.
CONSTITUTION: A mask 1 held between a printing drum 2 and recording paper 3 is fixed by a screw 11 on a frame 8 whose coefficient of linear expansion is large. At high temperature, dirty printing usually occured at this temperature, could be avoided by the fast that the step (s) between printing drum 2 and mask 1 becomes large owing to the extension of span length (l). Also, at low temperature, blurred printing usually occured at this temperature, could be avoided by the fact that the step (s) becomes small owing to the shrinkage of span length (l). Guiding pins 9, 10 are installed so as to prevent a bent of span caused by the temperature changes. Otherwise, plastic rings 12, 13 expandable by the temperature changes could be installed in alignment with the axis of printing drum 2.
