PURPOSE:To regulate the amount of aperture between an ink reservoir roller and blades by an operating board by providing an operating drive mechanism to independently drive each of split blades by driving the forward and backward regulating cam of the blade. CONSTITUTION:Split blades 32 are connected in such a way as to be independently operated with a blade regulating cam 58, a blade backward auxiliary cam 63, a motor 49 with a decelerator to drive these cams 58 and 63, and a manually operable shaft 51. The amount of apertures between the pot roller 27 and the peripheries of each split blade 32 is detected through a follow shaft 52 and a potentiometer 60 and displayed on a display meter. |
