Abstract

PURPOSE: To enable printing causing little noises without needing an ink ribbon, and to facilitate two color printing according to a line system by using hard felt, etc. to which ink is impregnated as a printing stylus for the impact dot printer.
CONSTITUTION: The printing stylus 3 is a rod with a circular section made of a material of the hard felt, etc. to which ink is impregnated, and held by means of a holder 4, and the holder 4 is mounted to a cantilever spring 9 consisting of a leaf spring of a magnetic substance at projections 4b. A rear end contacts with a stopper 7 in a printing unit 5 brought to a waiting condition through the excitation of a solenoid 10, and the ink of the stopper 7 consisting of felt, etc. to which ink is impregnated penetrates to the printing stylus 3 through a liquid flowing hole 4a at that time. When conduction to the solenoid 10 is interrupted by printing signals, the cantilever 9 inclines forward, a tip of the printing stylus 3 is impacted onto a form 2 on a platen 1 and printing is conducted. The two color printing is performed in two stage printing unit rows to which different ink is impregnated.
