发明名称 RECORDING HEAD FOR MAGNETIC INK RECORDER
摘要 PURPOSE:To provide the titled apparatus in which a thick protrusion is obtained in the shape reducing magnetic concentration by providing a projected magnet and a magnetic member forming a slit opening facing each other near the tip of a recording needle made of a magnetic body through the recording needle. CONSTITUTION:A projected magnet 16 is arranged near the tip of a recording needle 14 made of a magnetic body and a slit G is formed between the magnet 16 and the recording needle facing the magnet 16 through the recording needle 14 while a magnetic member 17 forming a slit opening E is provided near the tip of the recording needle. This can strengthen the magnetic force of the tip of the recording needle and a magnetic ink at the slit opening thereby always ensuring a protrusion in the shape and the supply of the magnetic ink stably.
