Abstract

PURPOSE:To perform pressing and collection of ink simultaneously by one ink pump by using the ink pump prepared by arranging diaphragms having different pressing areas in a pressure chamber and an ink chamber and by fitting both diaphragms to a plunger through the intermediary of a retainer. CONSTITUTION:The pressure chamber 26 and the ink chamber 29 are provided in the ink pump and the diaphragms 32 and 33 different in pressing area are arranged in the respective chambers. Both diaphragms are fitted to the plunger 34 making reciprocating motion by the force of a magnet coil 36 and a spring 37 through the intermediary of the retainer 35. One ink pump is miniaturized by giving thereto functions of pressing and collection of ink and thereby the ink-circulating device can be miniaturized.
